These tax forms are crucial for individuals and businesses alike, ensuring compliance with HMRC regulations and providing the necessary documentation for tax calculations, payments, and refunds. This article provides a detailed overview of the 50 most commonly used tax forms in the UK, offering insights into their purposes, who should use them, and how they fit into the broader taxation system.


Tax Form IDs For Short


Why Understanding Tax Forms is Crucial

Whether you're self-employed, running a business, or simply an individual filing your annual tax return, understanding the correct tax forms is critical. Filling out the wrong form or missing a form can result in delays, fines, or even legal issues. HMRC offers a vast array of forms, each with its specific purpose, catering to different taxpayer categories such as individuals, sole traders, businesses, landlords, and more. The key to hassle-free tax compliance lies in knowing which forms apply to your situation and how to use them correctly.


The Role of Form IDs

Every tax form is identified by a unique code or ID, which makes it easier to track and reference the appropriate forms. These identifiers are often a combination of letters and numbers, providing a quick reference to what the form entails. For example, the "SA100" form is the main form used for filing a Self Assessment tax return. For businesses, "CT600" refers to the corporation tax return form. Understanding these IDs will help you streamline your filing process and avoid confusion.


Keeping Track of Deadlines

One of the main challenges UK taxpayers face is keeping up with deadlines for filing tax returns. Different forms have varying deadlines. For instance, Self Assessment returns (SA100) must be submitted online by 31 January following the end of the tax year, while paper returns are due by 31 October. Missing a deadline can result in penalties, so it’s vital to stay on top of your tax obligations.


Digital Tax Filing: Making Tax Digital (MTD)

The UK government has been rolling out its "Making Tax Digital" initiative, which aims to streamline tax reporting by requiring many taxpayers to submit their returns digitally. As of April 2024, MTD applies to VAT-registered businesses and will soon extend to other types of taxes. Forms such as the SA100 and VAT100 can now be submitted through HMRC’s digital platforms, reducing paperwork and increasing efficiency for both taxpayers and HMRC.

Navigating the UK Tax System

Navigating the UK's tax forms may seem overwhelming at first, but with a clear understanding of the key forms and their purposes, the process becomes more manageable. Whether you are an individual taxpayer, self-employed, or running a business, knowing which forms apply to your circumstances ensures compliance with HMRC and can help you avoid penalties. Keeping up with the latest tax regulations and filing deadlines is critical to staying on top of your tax obligations.


This comprehensive guide to the 50 most commonly used tax forms in the UK provides a solid foundation for understanding the tax landscape. By staying informed, you can confidently manage your tax affairs and ensure that your filings are accurate and timely.



Tax Form IDs For Short: What Should You Do If You Can’t Find the Right Tax Form for Your Situation?

Finding the right tax form can be a bit like searching for a needle in a haystack, especially if you're not a tax professional. If you’re trying to navigate the UK's maze of tax forms, it can be frustrating to know which one applies to your situation. Fear not, though! There’s a method to the madness, and by following a step-by-step process, you can find the right form—or better yet, make a smart decision about whether you should be handling this yourself at all.


Step 1: Assess Your Tax Situation

The first step is to clearly understand your specific tax situation. Are you self-employed? Do you own a business? Are you employed but need to claim certain deductions, or maybe you’ve just moved to the UK from abroad? Your situation dictates which tax forms you need. For example, if you’re a contractor, forms like the CIS300 might be relevant, but if you’re a landlord, you’ll be dealing with forms like the SA105.


Take a moment to write down the sources of your income, any investments you’ve made, and the kinds of deductions or credits you might be eligible for. If you’re unsure where to start, HMRC’s website provides general guidance on the types of taxes and situations they cover. This is crucial because knowing whether you need to submit a Self Assessment return or a VAT return will steer you in the right direction.


Step 2: Use HMRC’s Online Resources

Once you have a grasp of your tax situation, your next step is to dive into the HMRC online portal. This might sound intimidating, but HMRC has made significant strides in making tax filing user-friendly with its online tools. Head to the HMRC website and use their search function to look for forms based on the keywords relevant to your situation. For example, if you are self-employed and need to report income, searching for “Self Assessment forms” should lead you to the SA100 form.


HMRC also provides online guides that help identify what forms are needed for specific tax activities like VAT, corporation tax, or income tax. A key resource is the Tax Returns Library, which includes downloadable versions of almost every tax form you could need.


Step 3: Call HMRC Helpline

Sometimes, HMRC’s online resources are not enough to clarify things, and let’s be honest—tax jargon can get confusing. In cases where you’re still stumped, calling HMRC’s helpline can save you hours of stress. While phone lines might be busy (we’ve all been there), the agents are trained to guide you through the form-finding process. Whether it’s identifying a form or figuring out which parts of a form apply to your situation, HMRC support can point you in the right direction.


When calling, have your National Insurance number, UTR (Unique Taxpayer Reference), or VAT registration number handy. This helps the agents quickly pull up relevant information and guide you through the maze of forms.


Step 4: Opt for a Tax Accountant

Here’s the thing—when it comes to taxes, sometimes it’s better to hand the reins over to a professional. If you’re spending hours agonizing over which form to use, hiring a tax accountant can be a game-changer. The complexity of UK tax forms can trip up even seasoned taxpayers, especially when you start dealing with things like capital gains, foreign income, or multiple income streams. Tax accountants are like your GPS through the tax jungle—they know the fastest routes and all the shortcuts.


Opting for a tax accountant isn’t just about avoiding mistakes—it’s about saving time, stress, and potentially money. For instance, a good accountant will not only ensure you’re filing the right forms but also that you’re maximizing any tax reliefs or allowances you’re entitled to. Let’s say you’re a small business owner: hiring a tax accountant might help you discover deductions and credits you didn’t even know existed, like claiming capital allowances or R&D tax credits.


Moreover, if HMRC ever questions your filings, having a tax accountant means you have a professional who can communicate directly with HMRC on your behalf. No need to scramble and figure out forms like SA370 (appeal against a tax penalty)—your accountant has got it covered.


Step 5: Use Tax Software

If you feel confident enough to handle things yourself but need a bit of assistance, tax software can bridge the gap between DIY tax filing and hiring an accountant. Platforms like Xero, Sage, and QuickBooks make it easier to file taxes, especially if you’re self-employed or run a small business. These tools often integrate directly with HMRC’s systems, allowing you to submit forms such as VAT returns or Self Assessment directly through the software.


The advantage here is that tax software helps prevent mistakes by automating much of the process. The software will guide you to the correct forms based on the information you input, flag potential errors, and calculate tax liabilities. However, if your tax situation is complex (think multiple properties, international income, or trusts), a tax accountant might still be your best option.


Step 6: Look for Third-Party Guides and Blogs

Sometimes, HMRC’s official guidance can be a little too...official. Third-party guides, articles, and blogs written by tax professionals often provide simplified, real-world advice that’s easier to understand. A quick search for your tax situation might lead you to resources written by accountants, financial bloggers, or tax service websites, which explain the forms and filing process in plain English.


For example, if you’re searching for tax advice as a freelancer, you’ll find plenty of articles that guide you through which forms to use, like SA103S for simplified self-employment income reporting. These guides often include handy tips for avoiding common mistakes, like underreporting income or missing important deductions.


Step 7: Join Tax Forums or Communities

Another option is to tap into the collective wisdom of fellow taxpayers. Online forums like MoneySavingExpert or even Reddit's UKPersonalFinance can provide insights into what forms others in similar situations are using. Sometimes, the questions you have might already have been asked and answered by someone else, giving you a shortcut to the solution.


Forums can also be helpful when dealing with unusual situations—such as managing foreign rental income or claiming tax back on investment losses—where other people’s experiences might shed light on which forms to use.


Step 8: Review the Forms You Do Have

One often overlooked step is to review any forms you’ve already submitted. For example, your P60 might give you clues about the next form you need to fill in for other claims or deductions. If you’re moving from employment to self-employment, looking at past tax returns can help clarify your new requirements. Forms like the SA110 can also guide you through manual tax calculations, so you’re prepared for the following tax year.


Step 9: Check HMRC Deadlines and Penalties

Before you start filling out any forms, always double-check the deadlines associated with them. If you miss a deadline, you may face penalties that add stress (and cost) to the process. Forms like the SA100 for Self Assessment or VAT100 for VAT returns have strict deadlines, and filing late can result in automatic fines.


Having an accountant helps avoid these penalties since they’re always up to date with the latest HMRC deadlines, ensuring that nothing slips through the cracks.


Don’t Go It Alone!

The key takeaway here is: you don’t have to tackle the UK tax system by yourself. Yes, HMRC offers plenty of resources, but if you’re in over your head, opting for a tax accountant is often the best way forward. Whether you’re dealing with simple Self Assessment or complex corporate tax, a tax professional can guide you through the process, find the right forms, and save you from the stress of potential penalties.

Taxes are inevitable, but the confusion doesn’t have to be. Taking a proactive approach and enlisting the help of an accountant when needed ensures you stay compliant while making the most of any tax-saving opportunities available to you.



Tax Form IDs For Short: How Do You Check the Status of Your Submitted Tax Forms?

Checking the status of your submitted tax forms in the UK can seem like a daunting task, especially with all the jargon, portals, and timelines involved. However, HMRC has made significant strides in simplifying the process. Whether you’re eagerly awaiting confirmation of your Self Assessment submission or just want to make sure your VAT return has been processed, there’s a clear step-by-step way to keep track of everything.

So, here’s how you can check the status of your submitted tax forms in the UK, explained in an informal, easy-to-digest way.


Step 1: Log Into Your HMRC Online Account

The first step in checking the status of any submitted tax form is to log into your HMRC account. This is the gateway to all your tax records, so if you haven’t already set one up, you’re going to need to. Here’s what you need:


  • Government Gateway ID: When you registered with HMRC, you would have been given this ID. If you’ve forgotten it (don’t worry, we all do), there’s a simple recovery process. You’ll just need your National Insurance number and a few security questions to get back in.

  • Password: You’ll also need the password associated with your account. Again, HMRC has a password recovery option if you can’t remember.


Once you’re logged in, your dashboard will give you access to all the information related to your taxes, from Self Assessment to VAT, PAYE, and more.


Step 2: Navigate to “Your Tax Account”

After you’ve logged in, you’ll be taken to your main dashboard. Here, you should look for something labeled “Your tax account” or “Self Assessment” (if you’re an individual). If you’re managing business taxes, you’ll likely see “Business tax account” or “VAT”, depending on the type of tax form you’re dealing with.


Here’s an example: Let’s say you’ve submitted your SA100 Self Assessment form for the year. To check the status, navigate to the Self Assessment section of your account. Here, you’ll see a summary of your most recent submission, including whether it’s been processed, any outstanding payments, or additional documents needed.


Step 3: Look for the “View Submitted Returns” or “View Tax Returns” Option

Once you’re in the relevant section (like Self Assessment or VAT), look for an option that says something like “View Submitted Returns” or “View Tax Returns.” This is where HMRC lists all the returns you’ve filed. For Self Assessment, this will show details for each year’s return. If you’ve recently filed, this section will show the submission date and status—whether it’s been received, processed, or still pending.


For VAT or corporation tax submissions, this will also give you a record of the status of each return you’ve submitted, including whether there’s any outstanding action needed on your part.


Step 4: Check the Submission Confirmation Message

If you’re like me, you probably get a little nervous after clicking “submit” on something as important as a tax form. One of the first things HMRC does after you’ve submitted a form online is to generate a submission confirmation message. This message should pop up immediately on your screen after you file your return, and it will contain a unique submission reference number.


This is an important part of the process because it’s proof that HMRC has received your submission. Make sure to save or print this confirmation for your records.

What happens if you missed it? No worries! HMRC will also send you an email confirmation to the address linked to your account, so you can always find that in your inbox. Be sure to double-check your spam folder just in case.


Step 5: Look at Your Payment Status

While checking the status of your submitted tax forms, it’s also important to check whether you owe any payments or are due a refund. This section of your account will usually show up right next to your form submission status. It will tell you:


  • How much you owe (if anything)

  • The due date for any payments

  • Whether any payment has been processed


For example, if you’ve submitted a Self Assessment form and owe taxes, the system will show you how much you owe and the due date by which you need to pay to avoid penalties.


On the flip side, if you’re due a refund (say, if you overpaid on your PAYE), the status will show whether that refund has been processed and the expected payment date.


Step 6: Track Deadlines and Processing Times

Tax forms aren’t processed immediately after submission, so it’s important to keep an eye on HMRC’s processing times. For example, Self Assessment returns typically take around 72 hours to be processed. For VAT returns, processing might be faster or slower, depending on the time of year.


HMRC usually updates your account once the form has been reviewed and accepted. If you’ve submitted your form and it still says “pending” or “in process,” don’t panic. Give it a few business days, especially during busy filing periods (like the end of January for Self Assessment returns).


Step 7: Dealing With Potential Errors

Sometimes, even after submitting your form, you might notice an error. Let’s say you accidentally input the wrong income figure or forgot to claim a deduction. In such cases, HMRC gives you a window to make amendments.


For Self Assessment returns, you can make changes up to 12 months after the filing deadline. Simply log back into your HMRC account, navigate to the “Self Assessment” section, and choose the option to amend your return. HMRC will then update the status once the amendment has been processed.


If you need to amend a VAT return, there’s a different process. You can make corrections directly on your next VAT return if the error is below £10,000. However, for larger errors, you’ll need to submit a separate VAT652 form.


Step 8: Contact HMRC If You’re Still Unsure

If you’ve followed the steps above and still can’t find the status of your form, it’s time to contact HMRC directly. This is especially important if you’re dealing with complex tax situations or suspect something has gone wrong with your submission.


HMRC’s helpline for Self Assessment is typically your best bet. Be prepared for long wait times, especially during busy periods. But once you’re through, they should be able to check your submission and give you a clear answer on the status. You might need to provide your submission reference number or National Insurance number, so have those ready.


If calling isn’t an option, you can also send an inquiry through HMRC’s online web chat or even send them a letter. Just be sure to include all the relevant details, including your reference number and the date of submission.


Step 9: Consider Using Tax Software

If all of this still feels a bit overwhelming, consider using tax software. Many of these tools integrate directly with HMRC’s systems, meaning you can track the status of your submissions right within the software. Programs like Xero, QuickBooks, and FreeAgent allow you to submit forms like VAT returns, Self Assessments, and corporation tax returns with the click of a button, and you can track the status through the software’s dashboard.


Tax software often provides additional features, such as automated reminders for deadlines and pending actions, which can be incredibly helpful if you’re juggling multiple tax responsibilities.


Checking the status of your submitted tax forms in the UK isn’t as tricky as it sounds once you know the steps. From logging into your HMRC account to reviewing submission confirmations and even dealing with amendments, the process is fairly straightforward. By staying organized and keeping track of your submissions, you can ensure that everything is processed smoothly—and avoid any nasty surprises from HMRC down the line.


If all else fails, don’t hesitate to call HMRC or enlist the help of a tax accountant or software to make sure you stay on top of your tax obligations.



Tax Form IDs For Short: How Can You Amend a Tax Form after Submission?

So, you've hit that "Submit" button on your tax form, and only later you realize there's a mistake. Maybe you forgot to include some income, or you accidentally claimed an expense that you’re not eligible for. No need to panic—luckily, in the UK, amending a tax form after submission is not only possible but quite straightforward, as long as you act within the right time frame. In this guide, I’ll break down the process of how you can amend a submitted tax form, using real-life examples to help clarify the steps.


Why You Might Need to Amend a Tax Form

Let’s start by discussing some common scenarios where you might need to amend a tax form. This could be because:


  • You entered the wrong amount of income or expenses.

  • You forgot to include certain income, like dividends or rental income.

  • You claimed tax relief that you’re not eligible for.

  • Your circumstances changed after you submitted the form, such as receiving a refund for a business expense.


The list goes on, but regardless of the reason, HMRC allows you to correct your mistakes for up to 12 months after the filing deadline for that tax year. The sooner you spot an error, the better. So, let’s dive into the steps for fixing it.


Step 1: Identify the Type of Tax Return You Submitted

The first step is figuring out exactly which tax form you need to amend. In most cases, the common tax returns you’ll be dealing with are:


  1. Self Assessment tax return (SA100)

  2. VAT return

  3. Corporation tax return (CT600)

  4. PAYE submissions


Each type of tax form has a different amendment process, so it’s essential to know which one you’re working with. For this example, let’s focus on the Self Assessment tax return (SA100), as this is the most common form individuals need to amend. However, I'll also touch on VAT and corporation tax.


Step 2: Log into Your HMRC Online Account

Once you've identified the form you need to amend, the next step is to head over to your HMRC online account. If you don’t have one yet, now’s the time to set it up! Most tax-related tasks can now be completed digitally, and the government has streamlined the process to make it user-friendly.


To log in, you’ll need your Government Gateway ID and password. If you’ve forgotten these, don’t worry—HMRC provides recovery options that allow you to retrieve your login details using your National Insurance number and some security questions.


Step 3: Go to the “Self Assessment” Section (for SA100)

If you need to amend your Self Assessment tax return, after logging in, navigate to the Self Assessment section. Here, you’ll see an overview of your submitted tax returns for each year. Find the relevant year that you need to amend and click on it.

Let’s say you’ve submitted your 2022/2023 Self Assessment, but after filing, you realized you forgot to include some rental income. No biggie. Once you’re in the right tax year, there should be an option to “Amend return” or something similar. Click on that, and you’ll be able to correct the mistake.


Step 4: Make the Corrections

Once you’re in the amendment section, you’ll be able to correct any of the information you previously submitted. For example, let’s go back to our rental income scenario. If you forgot to include £3,000 in rental income, just enter the correct figure and save the changes.


You can also amend other areas of the return, such as expenses, tax reliefs, and any capital gains you may have forgotten to declare. Once you’ve made the changes, double-check everything to make sure the figures are correct. The last thing you want to do is submit an amended return with another mistake!


Step 5: Resubmit the Amended Form

After making all necessary changes, you’ll be prompted to resubmit the amended tax form. HMRC will process the amendment just like they did with your original submission. Depending on the correction, you might need to make an additional payment (if you owe more tax), or you could be due a refund.


HMRC will usually send you a confirmation of the changes by email, and you can always log back into your account to check the status of the amended return.


Example: Correcting a Self Assessment Return

Let’s use a more detailed example here. Imagine you’re self-employed and submitted your Self Assessment tax return on time. However, a month later, you remember you spent £500 on business supplies that you forgot to claim as an allowable expense.

Here’s how you would fix it:


  1. Log into your HMRC account.

  2. Go to the Self Assessment section and select the year you want to amend.

  3. Click “Amend return”.

  4. Navigate to the Expenses section.

  5. Enter the £500 you forgot to claim.

  6. Review your return, ensuring all other information is still correct.

  7. Submit the amended return.


Once submitted, HMRC will recalculate your tax bill based on the additional £500 deduction. If you overpaid taxes as a result of the error, HMRC will issue a refund, usually within a few weeks.


Amending VAT Returns

Amending a VAT return is slightly different. For small errors (less than £10,000), you can usually correct the mistake on your next VAT return. Here’s how:


  1. Identify the error on your VAT return (e.g., maybe you underreported sales by £1,000).

  2. On your next VAT return, adjust the sales figure to account for the previous mistake.

  3. Submit the return as usual, and HMRC will take care of the rest.


For errors over £10,000 or mistakes made over four years ago, you’ll need to use the VAT652 form to notify HMRC.


Amending Corporation Tax Returns (CT600)

For businesses that need to amend a corporation tax return (CT600), the process is similar to Self Assessment but typically involves more steps. You can amend a Corporation Tax return within 12 months of the filing deadline. Here’s a brief overview:


  1. Log into your company’s HMRC account.

  2. Navigate to the CT600 form for the year you wish to amend.

  3. Select “Amend Return” and make the necessary changes, such as correcting income or adjusting expenses.

  4. Resubmit the amended return, and HMRC will update your corporation tax bill.


Step 6: Keep a Record of Your Amendments

Finally, once you’ve successfully amended your tax form, make sure you keep a record of the changes. HMRC recommends keeping records for at least five years, so print or download your amended return and store it somewhere safe. This way, if HMRC ever asks for clarification on your changes, you have everything on hand.


What Happens Next?

Once HMRC processes your amended return, they will notify you of any additional tax owed or any refunds you’re due. Typically, you’ll receive this notification via email or letter within a few weeks.


If your amendment results in you owing more tax, you’ll be given a payment deadline (usually within 30 days) to settle the balance. On the flip side, if you’ve overpaid, HMRC will automatically issue a refund, which could either be credited to your bank account or used to offset any other outstanding tax liabilities.


Stay On Top of It!

Making a mistake on your tax return is a common occurrence, but the important thing is to stay proactive and fix the error as soon as possible. Whether it’s updating your Self Assessment return, correcting a VAT return, or amending a corporation tax submission, HMRC gives you the tools and time to make things right. So don’t panic—just log into your account, make the corrections, and resubmit.


And if in doubt, always consider reaching out to a tax professional to ensure everything is squared away correctly!



How Can You Amend a Tax Form After Submission?

So, you’ve gone through the hassle of filing your UK tax return, hit the submit button, and breathed a sigh of relief. But then, something happens: maybe you spot an error, realize you forgot to include a source of income, or perhaps even made an innocent mistake. What now? Well, the good news is that HMRC (Her Majesty's Revenue and Customs) understands these things happen, and they’ve got a pretty straightforward process for amending tax returns after submission.


In this guide, I’ll walk you through how to amend a tax return in the UK, step-by-step. Whether it's a Self Assessment tax return, VAT return, or even corporation tax, we've got you covered.


Step 1: Identify What You Need to Amend

The first step might sound obvious, but it’s crucial: you need to pinpoint exactly what needs changing. Is it your income? Maybe you forgot to include an additional freelance gig or rental income. Or perhaps it's an expense claim that’s incorrect—like you claimed for a business trip that didn’t actually happen, or you calculated the mileage wrong.

Take the time to go back through your submission and identify every mistake. If it's something small, like an underclaimed expense, it might be tempting to leave it. But remember, even small errors can lead to larger discrepancies later on, so it’s better to fix them sooner rather than later.


Step 2: Check the Deadline for Making Amendments

Here’s the catch: there’s a deadline for when you can amend your tax returns. For most types of UK tax returns, you can amend them up to 12 months after the filing deadline. For example, if you filed your 2022/2023 Self Assessment by the 31 January 2024 deadline, you have until 31 January 2025 to make any changes.


If you’re outside this 12-month window, you’ll need to contact HMRC directly to explain the situation, but more on that later.


Step 3: Log Into Your HMRC Online Account

Once you've identified what needs to change and you’re still within the amendment window, it's time to log into your HMRC online account. If you’ve submitted your return online, the easiest way to amend it is through your HMRC account.


  1. Go to the HMRC login page and enter your Government Gateway ID and password. If you’ve forgotten either, don’t panic; HMRC has a password recovery system.

  2. Once logged in, navigate to the relevant section—whether it’s Self Assessment or VAT returns.


For a Self Assessment amendment, go to the Self Assessment section, and you should see your tax return for the year you want to amend. There will be an option to "Amend Return."


Step 4: Make the Changes

Now comes the easy part—making the actual changes. Once you're in the amendment section of your tax return, you can correct or add information as needed.

For example, say you forgot to include £2,000 worth of freelance income on your Self Assessment. You can now enter that information under the additional income section. Or, perhaps you realized you miscalculated your business expenses. Simply update the expense totals in the relevant section of your return.


Be thorough here! It’s important to double-check everything before resubmitting, as this is your chance to fix any mistakes that might cost you later on.


Example: Fixing an Income Reporting Mistake

Let’s say you filed your Self Assessment but forgot to include £1,500 you earned through a side business in November 2022. Here’s how you’d fix it:


  1. Log in to your HMRC account.

  2. Go to your Self Assessment for the tax year 2022/2023.

  3. Click on "Amend return."

  4. Navigate to the section for self-employment income and add the missing £1,500.

  5. Check the rest of your return to make sure everything else is correct.

  6. Submit your amended return.


HMRC will process the amendment, and if it results in more tax due, they’ll send you an updated bill. Conversely, if it means you overpaid, they’ll arrange for a refund.


Step 5: Submit and Save a Copy

After making the changes, it’s time to submit the amended return. HMRC will process the amendment and, as with your original submission, you'll receive a confirmation email.


It’s a good idea to save or print the updated return for your records. HMRC suggests keeping your records for at least five years after the tax year ends, just in case they have any future questions.


Step 6: Dealing with VAT and Corporation Tax

If you're amending a VAT return or corporation tax return, the process is similar but has a few differences.


For VAT, if the error is small (less than £10,000), you can adjust it on your next VAT return. If it's larger than £10,000, you’ll need to submit a VAT652 form to HMRC, detailing the error and correcting it.


For corporation tax, you can amend the return within 12 months of the filing deadline. The process is similar to Self Assessment: log into your account, find the CT600 return you need to amend, and submit the changes.


What Happens Next?

Once HMRC receives your amended tax return, they’ll review the changes. If the amendment results in a different tax calculation, HMRC will issue an updated statement. You might find that you owe more tax, in which case HMRC will tell you how much you need to pay and when.


Conversely, if you overpaid because of the mistake, HMRC will process a refund, which they’ll send either to your bank account or via cheque. Refunds typically take a few weeks, but it can be faster if you’ve provided your bank details.


Step 7: What If You Missed the Amendment Deadline?

So, what if it’s been more than 12 months since the deadline, and you need to make a change? This happens more often than you’d think—maybe you didn’t realize the mistake until years later.


In this case, you can’t amend the return online, but you can still contact HMRC. Write to them explaining the situation, and they’ll guide you through the process. This might involve submitting what’s called an “overpayment relief claim”. It’s not as quick as amending the return yourself online, but HMRC will still process it and correct the error.


Example: Fixing a Corporation Tax Return Outside the Deadline

Say you’re the director of a small business, and a couple of years after filing your CT600, you realize that you claimed too much in R&D tax credits. Since it’s outside the 12-month window, you’ll need to contact HMRC in writing, explain the error, and wait for them to process your claim.


Step 8: Avoid Future Mistakes

Now that you've successfully amended your return, how can you avoid making the same mistake again next year? A good rule of thumb is to double-check everything before hitting that "submit" button.


Here are a few tips:

  • Keep organized records throughout the year. It’s much easier to file an accurate return if you have all your receipts, invoices, and income statements in order.

  • Use accounting software like QuickBooks or Xero, which helps keep track of your income and expenses and even integrates with HMRC’s systems.

  • If your tax affairs are complex, consider working with a tax accountant who can file the return on your behalf and catch any potential mistakes before submission.


Making a mistake on your tax return is no fun, but it's not the end of the world. The UK tax system is forgiving, and HMRC gives you plenty of time to fix errors. Whether you're amending a Self Assessment, VAT return, or corporation tax return, the process is straightforward, especially if you’re within the 12-month amendment window.

Take your time, follow the steps, and ensure your returns are accurate moving forward to avoid penalties and interest charges. If you ever feel stuck, don’t hesitate to consult a professional—tax accountants are lifesavers for a reason!



How Can You Submit A Self-Assessment Tax Return In The UK If You Are Living Abroad?

Living abroad can bring all sorts of perks—new experiences, cultures, and possibly even sunshine if you’ve escaped the British weather. But one thing that doesn’t go away when you pack up and move abroad is your UK tax responsibilities. If you’ve got income coming in from the UK while you’re living overseas, chances are you’ll need to submit a Self Assessment tax return.


The process is relatively straightforward but does come with a few extra steps and considerations. In this guide, I’ll break down how to submit a UK Self Assessment tax return from abroad, what forms to use, and provide some real-world examples to help you get it right.


Step 1: Check If You Need to Submit a Self Assessment Tax Return

Just because you’ve moved out of the UK doesn’t mean you automatically get a pass on filing a Self Assessment return. In fact, if you’re still earning income from the UK—whether that’s through renting out a property, receiving a UK pension, dividends from UK investments, or earning self-employment income—you’re still on HMRC’s radar.

Common reasons why expats need to file a Self Assessment tax return include:


  • Renting out a UK property

  • Earning UK dividends or interest

  • Self-employment income in the UK

  • Receiving a UK pension

  • Capital gains from selling UK property or assets


If any of these apply to you, then you’re probably going to need to submit a Self Assessment return. And don’t worry, even if you’re living abroad, the process of filing the return isn’t that different from doing it in the UK.


Step 2: Register for Self Assessment

If you haven’t already registered for Self Assessment, this is your first port of call. The process for registering is the same whether you’re in the UK or abroad, but here’s a quick refresher:


  1. Head to the HMRC website and register online for Self Assessment. You’ll need to provide your personal details, including your National Insurance number and details of any UK income you’re receiving.

  2. If you’re self-employed, you’ll also need to register as self-employed, which you can do at the same time.


Once registered, HMRC will send you a Unique Taxpayer Reference (UTR). This is a 10-digit code that you’ll need to use every time you file your Self Assessment.


Step 3: Be Aware of Non-Resident Tax Rules

If you’re a non-UK resident (i.e., you live abroad for most of the year), your tax obligations might be a little different from someone who lives full-time in the UK. The key factor is how many days you spend in the UK during the tax year. HMRC uses something called the Statutory Residence Test to determine your residency status.

Generally speaking:


  • If you spend 183 days or more in the UK during the tax year, you’re considered a UK resident for tax purposes.

  • If you spend fewer than 183 days in the UK, you might be considered a non-resident.


If you’re classified as a non-resident, you only pay tax on your UK income (such as income from UK properties or pensions), while your foreign income is usually exempt from UK tax.


Example: The Case of an Expat Landlord

Let’s say you’ve moved to Spain but still rent out a property in London. You’re earning rental income from this property and are considered a non-resident landlord. Even though you’re living in Spain, you still need to declare your UK rental income via a Self Assessment tax return.


You can also apply for the Non-Resident Landlord Scheme, which lets your tenant or letting agent pay your rent without deducting tax at source, meaning you’ll pay the tax directly through your Self Assessment.


Step 4: File Your Tax Return Online

Now that you’re registered and have your UTR, you can file your tax return online. Here’s how:


  1. Log into your HMRC account: Using your Government Gateway ID and password (you should have set these up when registering), log into your online account.

  2. Navigate to the Self Assessment section: From your dashboard, select the “Self Assessment” tab, where you’ll be able to see the tax year you need to file for.

  3. Fill in the details: The online form will guide you through each section, from personal details to income details. This is where you’ll declare all your UK income, such as rental income or UK pension payments.

  4. Pay attention to foreign tax credits: If you’re paying tax on the same income both in the UK and abroad (for example, if you’re earning UK income while living in Spain), you might be able to claim foreign tax credits to avoid being taxed twice on the same income. Use the HS302 form to claim Foreign Tax Credit Relief.

  5. Submit and pay: Once you’ve completed the form, double-check everything (you don’t want to be amending it later), and hit submit. You’ll receive a confirmation email once it’s been successfully submitted. You can also pay any outstanding tax online via your HMRC account.


Step 5: Don’t Forget the Deadlines

The deadlines for filing and paying your Self Assessment remain the same, whether you’re living in the UK or abroad:


  • Paper returns: Must be submitted by 31 October following the end of the tax year.

  • Online returns: Must be submitted by 31 January following the end of the tax year.

  • Payments: Any tax you owe must also be paid by 31 January (the same day as the online submission deadline).


Missing these deadlines could result in penalties, so make sure you mark these dates on your calendar or set up reminders!


Step 6: Dealing With Currency Conversion

One aspect of filing a tax return while living abroad is dealing with foreign currencies. If you’re earning income abroad but need to declare UK income, you’ll need to convert any foreign earnings into British pounds (GBP). HMRC requires you to use their official exchange rates, which are updated regularly on their website.


For example, if you’re earning rental income in Spain, you’ll need to convert it to GBP using HMRC’s monthly exchange rates. Be sure to use the correct rates for the period in which you earned the income.


Step 7: How to Pay UK Tax From Abroad

So, you’ve submitted your tax return, and HMRC has told you how much tax you owe. But how do you actually make the payment if you’re living abroad?

HMRC allows you to pay your tax online, and they accept a variety of payment methods, including:


  • Debit or credit card: You can pay directly through your online HMRC account.

  • Bank transfer: You can transfer money to HMRC’s bank account, but be aware of international transfer fees if you’re paying from a foreign account.

  • Direct debit: If you have a UK bank account, you can set up a direct debit payment to cover the amount you owe.


Example: Paying Tax From Abroad

Let’s say you’re an expat living in Australia, and you’ve just submitted your Self Assessment. You owe HMRC £3,000 in taxes. You can transfer the money from your Australian bank account, but keep in mind that your bank might charge a foreign transaction fee. To avoid this, some expats prefer to keep a UK bank account open specifically for handling things like tax payments.


Step 8: Keep Records

Finally, just because you’re living abroad doesn’t mean you’re exempt from keeping proper records. HMRC recommends keeping records for at least five years after the 31 January submission deadline. This includes documents like:


  • Payslips (for UK pensions or salary)

  • Bank statements

  • Rental income receipts

  • Details of expenses you’ve claimed


If HMRC ever questions your return, having these records handy will make the process much smoother.


Submitting a Self Assessment tax return while living abroad isn’t too different from filing within the UK, but there are some extra considerations to keep in mind. Whether it’s checking your residency status, converting foreign currency, or navigating the Non-Resident Landlord Scheme, staying organized and on top of deadlines will make the process much easier.


And, if in doubt, don’t hesitate to get professional tax advice—after all, the last thing you want while living your best life abroad is to deal with tax headaches!
