What Exactly Is a P45 Form and Why Does It Matter?
So, you’ve just left a job, or maybe you’re about to start a new one, and someone mentions a P45 form. Sounds like just another piece of paperwork, right? Well, not quite. A P45 is a critical document in the UK’s tax system, and whether you’re an employee or a business owner, understanding it can save you from tax headaches. Let’s break it down in a way that makes sense, with all the details you need to know for the 2024-2025 tax year.
The Basics: What Is a P45?
Let’s start at the beginning. A P45, officially called “Details of Employee Leaving Work,” is a form your employer gives you when you leave a job. It’s part of the Pay As You Earn (PAYE) system, which is how most UK workers pay income tax and National Insurance contributions (NICs). The form records how much you’ve earned and the tax you’ve paid during the tax year (6 April to 5 April) up to the point you left that job. It also includes your tax code, which tells employers how much tax to deduct from your salary. Think of it as a snapshot of your tax situation at the moment you walk out the door.
The P45 has four parts: Part 1 goes to HM Revenue and Customs (HMRC), Part 1A is for you to keep, and Parts 2 and 3 are handed to your new employer (or Jobcentre Plus if you’re claiming benefits). This setup ensures everyone—HMRC, you, and your new employer—has the info needed to keep your taxes on track. Without it, you might end up overpaying or underpaying tax, which is never fun.
Why It’s a Big Deal
Now, you might be wondering why this form is such a big deal. Here’s the thing: the P45 is like a tax passport for your next job. It tells your new employer your tax code and how much tax you’ve already paid, so they don’t accidentally slap you with an emergency tax code. Emergency tax codes, like 1257L W1 or M1, assume you’re earning the same amount every month, which can lead to overtaxing if you’ve only worked part of the year. For example, in the 2024-2025 tax year, the personal allowance is £12,570, meaning you don’t pay tax on income up to that amount. If your P45 is missing or incorrect, your new employer might not apply this allowance correctly, and you could lose out.
For business owners, issuing a P45 is a legal must-do when an employee leaves. Mess it up, and you could face HMRC penalties. Plus, it’s a chance to show you’re on top of your payroll game, which builds trust with your team.
What’s On a P45?
Right, let’s get into the nitty-gritty. A P45 isn’t just a random piece of paper—it’s packed with specific details. Here’s what you’ll find on it:
Your personal info: Name, address, National Insurance number.
Employer details: Their name, address, and PAYE reference number.
Employment dates: When you started and left the job.
Earnings and tax paid: Total taxable pay and tax deducted for the tax year so far.
Tax code: The code your employer used to calculate your tax (e.g., 1257L for the standard personal allowance).
Student loan info: If you’re repaying a student loan, it’ll show here.
Structure of a P45
Here’s a quick table to make sense of the 2024-2025 tax bands, which tie into how your P45 affects your tax calculations:
Tax Band | Income Range (2024-2025) | Tax Rate |
Personal Allowance | Up to £12,570 | 0% |
Basic Rate | £12,571 - £50,270 | 20% |
Higher Rate | £50,271 - £125,140 | 40% |
Additional Rate | Over £125,140 | 45% |
If your P45 shows you’ve already paid tax at the basic rate for £10,000 of your income, your new employer can pick up where your old one left off, ensuring you don’t get taxed twice on the same earnings.
When Do You Get a P45?
Here’s where it gets practical. Your employer is legally required to give you a P45 when you leave a job, whether you’re sacked, retire, or just move on to greener pastures. It should arrive with your final payslip or shortly after, either as a paper copy or electronically. If you don’t get one, don’t just shrug it off—ask your employer. They’re obligated to provide it, and HMRC doesn’t take kindly to employers who slack on this.
If you’re starting your first job or don’t have a P45 (maybe you lost it or your employer’s gone AWOL), your new employer will use a Starter Checklist instead. This form, available on GOV.UK, asks about your previous jobs, benefits, or student loans to figure out your tax code. It’s not as precise as a P45, so you might face emergency tax until HMRC sorts things out.
Common Pitfalls to Watch Out For
Be careful! The P45 process isn’t always smooth sailing. One common issue is errors on the form—like a wrong tax code or incorrect earnings. For instance, if your P45 says you earned £20,000 when you actually earned £15,000, your new employer might deduct too much tax. Always check the details and contact your old employer to fix any mistakes. If they’ve already sent Part 1 to HMRC, you’ll need to loop in HMRC to correct the record.
Another trap is losing your P45. You can’t get a replacement, but you can use a Starter Checklist to avoid emergency tax. And if you’re claiming Jobseeker’s Allowance, you’ll need Parts 2 and 3 to give to Jobcentre Plus, so keep them safe.
Real-Life Example: Sarah’s Tax Mix-Up
Picture this: Sarah, a 28-year-old graphic designer from Leeds, left her job at a small agency in January 2025. Her P45 showed she’d earned £18,000 and paid £1,200 in tax. She started a new job in February but forgot to hand over Parts 2 and 3. Her new employer put her on an emergency tax code, assuming she was earning £18,000 monthly, not annually. By March, she’d overpaid £400 in tax. After contacting HMRC and providing her P45, she got a refund, but it took weeks of hassle. Moral of the story? Hand over that P45 pronto, and double-check its details.
How a P45 Shapes Your Taxes and What to Do If Things Go Wrong
Now, let’s get into the meat of how a P45 actually affects your tax situation. It’s not just a piece of paper you hand over and forget about—it’s a key player in making sure you’re not overpaying or underpaying tax. Whether you’re hopping between jobs, claiming benefits, or running a business, the P45 can either be your best friend or a bit of a headache if you don’t handle it right. Let’s walk through the practical side, with some real-world tips for UK taxpayers and business owners in the 2024-2025 tax year.
How a P45 Affects Your New Job
So, you’ve landed a new gig—congrats! When you start, your new employer will ask for your P45 (specifically Parts 2 and 3). Why? Because it tells them your tax code and how much you’ve already earned and paid in tax this tax year. This is crucial for keeping your tax deductions on track. For example, if your P45 shows you’ve earned £8,000 and paid £600 in tax at your old job, your new employer can factor that in. They’ll use your remaining personal allowance (£12,570 for 2024-2025) and apply the correct tax rate to your new earnings.
Without a P45, your employer might put you on an emergency tax code, like 1257L W1 or M1. These codes assume you’re earning a full year’s salary in the months you’re working, which can lead to overtaxing. Say you start a job in October 2025 earning £2,000 a month. An emergency tax code might treat that as £24,000 annually, ignoring your earlier earnings or unused personal allowance. Result? You could lose hundreds in overpaid tax until HMRC adjusts it, which can take months.
Emergency Tax: The Sting and How to Fix It
Be careful! Emergency tax is one of the biggest traps linked to P45 issues. It often happens if you don’t give your new employer your P45 or if there’s a delay in HMRC processing it. In 2023-2024, HMRC reported that around 1.2 million workers were incorrectly taxed due to missing or late P45s, leading to an estimated £300 million in overpaid tax (source: HMRC Annual Report 2023-2024). If you’re hit with emergency tax, you’ll notice your payslip showing higher deductions than expected.
Here’s how to fix it:
Hand over your P45 ASAP: Give Parts 2 and 3 to your new employer immediately to update your tax code.
Check your payslip: Look for codes like W1 or M1, which signal emergency tax. If you see them, contact your employer or HMRC.
Contact HMRC: Use the Income Tax helpline (0300 200 3300) or check your Personal Tax Account on GOV.UK to update your details.
Claim a refund: If you’ve overpaid, HMRC will usually refund you automatically at the end of the tax year, but you can request it sooner via Form P50 if you’re not working.
P45 and Jobseeker’s Allowance
Now, if you’re not jumping straight into a new job and need to claim Jobseeker’s Allowance (JSA), your P45 is still important. You’ll need to give Parts 2 and 3 to Jobcentre Plus when you apply. Why? Because it shows your earnings and tax paid, which helps determine if you’re eligible for contribution-based JSA. For 2024-2025, JSA rates are £90.50 per week for those over 25, but your previous earnings (as shown on your P45) can affect whether you qualify and for how long (source: GOV.UK Jobseeker’s Allowance).
If you’ve lost your P45, don’t panic. Jobcentre Plus can use other proof of earnings, like payslips or a letter from your employer, but it’ll slow things down. Always keep Part 1A (your copy) safe for reference.
Business Owners: Your Role in Issuing P45s
Right, let’s flip the script. If you’re a business owner, issuing P45s is your responsibility when an employee leaves. HMRC is strict about this—failing to provide a P45 can lead to fines of up to £3,000 per employee for incorrect PAYE records (source: HMRC Penalties for Employers). You’ll need to use payroll software or HMRC’s Basic PAYE Tools to generate the form, ensuring all details (earnings, tax code, NICs) are accurate. Double-check the figures, as errors can cause problems for your former employee’s next job or tax refund.
Here’s a quick table to help business owners understand key P45 responsibilities:
Task | Details | Source |
Issue P45 | Provide within 14 days of employee leaving | |
Submit to HMRC | Send Part 1 electronically via Real Time Information (RTI) | |
Correct Errors | Amend via payroll software and notify HMRC within 30 days | |
Penalties for Non-Compliance | Up to £3,000 per employee for inaccurate or missing P45s |
Case Study: Raj’s Overtaxing Nightmare
Consider this: Raj, a 35-year-old IT consultant from Birmingham, switched jobs in July 2024. His old employer sent his P45 late, and it listed an incorrect tax code (1185L instead of 1257L). His new employer applied an emergency tax code, deducting £800 more than needed over three months. Raj checked his payslip, spotted the issue, and contacted HMRC with his P45 and payslips. They updated his tax code, and he got a £750 refund in October 2024. Lesson? Always verify your P45 details and act fast if something’s off.
Step-by-Step Guide: What to Do with Your P45 When Starting a New Job
None of us loves dealing with paperwork, but handling your P45 right can save you money. Here’s a simple guide:
Check Your P45: When you get it, review Part 1A for errors in your name, earnings, tax paid, or tax code.
Keep Part 1A Safe: Store it with your tax records (physical or digital) for reference.
Hand Over Parts 2 and 3: Give these to your new employer on your first day or as soon as possible.
Monitor Your First Payslip: Look for your tax code and deductions. If it’s wrong (e.g., emergency code), contact your employer immediately.
Contact HMRC if Needed: Use your Personal Tax Account or call HMRC to fix issues like overtaxing.
Track Refunds: If you’ve overpaid tax, check your tax account or expect a refund at the tax year’s end (5 April 2025). when you leave a job, and keep it in a safe place for future reference.
Managing Your P45 for a Smooth Job Transition
How to Fill Form P45: A Question-by-Question Guide
Right, so you’re an employer in the UK, and one of your employees is leaving. Now you’ve got to tackle the P45 form, which can feel like a bit of a faff if you’re not sure what goes where. Don’t worry—this guide will walk you through every question on the P45, step by step, with sample answers based on the official form from HMRC (version 12/15, as provided). We’ll make it dead simple, using a fictional employee to show you exactly how to fill it out correctly for the 2024-2025 tax year. Whether you’re a small business owner or an HR manager, this will help you get it right and keep HMRC happy. Here is a sample P45, in PDF, for your study only. If you need to fill it out online, here is its sample.
Why Getting the P45 Right Matters
Before we dive in, let’s talk about why this form is a big deal. The P45 is a legal requirement under the Pay As You Earn (PAYE) system, and it ensures your employee’s tax records are accurate when they move to a new job or claim benefits. Mistakes—like wrong earnings or tax codes—can lead to overtaxing, underpaying tax, or even HMRC fines of up to £3,000 per employee for incorrect records (source: HMRC Penalties for Employers). So, let’s get it spot-on.
For this guide, we’ll use the example of Emma Thompson, a barista at your Bristol cafe, who’s leaving on 15 November 2024 after earning £12,000 this tax year, with £800 in tax deducted. Her tax code is 1257L, and she’s not on a student loan plan. Ready? Let’s go through each question on the P45, using the fields from Part 1, as they’re the most detailed, and note where other parts differ.
Question 1: Employer PAYE Reference
What to Do: Enter your PAYE reference, which consists of an office number (3 digits) and a reference number (up to 10 characters). You’ll find this on your HMRC correspondence or payroll software.
Sample Answer: Office number: 123, Reference number: AB45678
Why It Matters: This identifies your business to HMRC, linking the P45 to your payroll records. Double-check it, as errors can mess up HMRC’s tracking.
Question 2: Employee’s National Insurance Number
What to Do: Fill in the employee’s National Insurance (NI) number, a unique identifier like AB123456C. You should have this from their onboarding documents or payslips.
Sample Answer: JM987654B
Why It Matters: The NI number ensures Emma’s tax and National Insurance contributions are recorded correctly. If you don’t have it, contact Emma or check HMRC’s records via your Real Time Information (RTI) system.
Question 3: Title and Surname or Family Name
What to Do: Enter the employee’s title (e.g., MR, MRS, MISS, MS, or other) and their surname or family name. Use capital letters, as instructed.
Sample Answer: Title: MS, Surname: THOMPSON
Why It Matters: This confirms the employee’s identity. Make sure it matches their official records to avoid confusion with HMRC or their new employer.
Question 4: Leaving Date
What to Do: Enter the date the employee stops working for you in the format DD MM YYYY. This should match the date on your final RTI submission for them.
Sample Answer: 15 11 2024
Why It Matters: The leaving date tells HMRC and the new employer when Emma’s employment ended, affecting her tax calculations. If she dies, enter the date of death instead.
Question 5: Student Loan Deductions
What to Do: Enter ‘Y’ if the employee is due to make student loan repayments; leave blank if not. Check their payroll records or ask them directly.
Sample Answer: (Blank)
Why It Matters: Since Emma isn’t repaying a student loan, you leave this blank. If ‘Y’ is entered incorrectly, it could trigger unwanted deductions at her next job.
Question 6: Tax Code at Leaving Date
What to Do: Enter the tax code used on the employee’s final payslip. If it’s a Week 1/Month 1 code (non-cumulative), mark an ‘X’ in the box below.
Sample Answer: Tax code: 1257L, Week 1/Month 1: (Blank)
Why It Matters: Emma’s 1257L code reflects the standard £12,570 personal allowance for 2024-2025. The Week 1/Month 1 box is blank because her code is cumulative, meaning her tax is calculated based on her total earnings for the year.
Question 7: Last Entries on Payroll Record/Deductions Working Sheet
What to Do: Complete this only if the tax code is cumulative (no ‘X’ in Question 6). Enter the week or month number of the last payroll entry, total pay to date, and total tax to date for the tax year (6 April 2024 to 5 April 2025). Leave blank if Week 1/Month 1 applies.
Sample Answer: Week number: 32, Month number: (Blank), Total pay to date: £12,000, Total tax to date: £800
Why It Matters: These figures show Emma’s earnings and tax paid up to 15 November 2024. They help her new employer continue her tax calculations correctly. If you use payroll software, these numbers come from your final RTI submission.
Question 8: This Employment Pay and Tax
What to Do: Fill this in only if the tax code is non-cumulative (Week 1/Month 1, with an ‘X’ in Question 6). Enter the total pay and tax for this employment. If the tax code is cumulative, leave blank, as the amounts are already in Question 7.
Sample Answer: (Blank)
Why It Matters: Since Emma’s tax code is cumulative, you skip this question. If it were non-cumulative, you’d enter her pay and tax just for this job, not the year’s total.
Question 9: Works Number/Payroll Number and Department or Branch
What to Do: Enter the employee’s works number, payroll number, or department/branch, if applicable. This is optional and depends on your company’s system.
Sample Answer: Payroll number: BT123, Department: Bristol Cafe
Why It Matters: This helps identify Emma within your payroll system, especially if you have multiple locations or large staff. It’s not mandatory, but it’s useful for clarity.
Question 10: Gender
What to Do: Mark an ‘X’ in the Male or Female box, based on the employee’s gender as recorded in your payroll.
Sample Answer: Female: X
Why It Matters: HMRC uses this for statistical purposes and to verify employee records. Ensure it matches Emma’s official details.
Question 11: Date of Birth
What to Do: Enter the employee’s date of birth in the format DD MM YYYY, as per their onboarding documents.
Sample Answer: 12 03 1990
Why It Matters: This confirms Emma’s identity and ensures HMRC’s records align. Errors here could cause issues with her National Insurance or pension.
Question 12: Employee’s Private Address (Part 1A Only)
What to Do: On Part 1A, enter the employee’s home address and postcode. This isn’t required on Parts 1, 2, or 3.
Sample Answer: 24 Elm Street, Bristol, BS1 2XY
Why It Matters: Emma keeps Part 1A, and this helps her verify her tax records or use it for a tax return. Ensure it’s accurate to avoid issues.
Question 13: Employer Name and Certification (Part 1A Only)
What to Do: Enter your business name and the date you’re issuing the P45. Certify that the details are correct.
Sample Answer: Employer name: Bristol Brew Ltd, Date: 15 11 2024
Why It Matters: This confirms the P45’s authenticity. Sign or electronically certify it to show HMRC you’ve completed it accurately.
Final Steps and Tips
Now, here’s the wrap-up. Once you’ve filled out the P45, ensure all parts (1, 1A, 2, and 3) are clear and identical. Send Part 1 to HMRC via your RTI submission, give Parts 1A, 2, and 3 to Emma, and remind her to keep Part 1A safe and give Parts 2 and 3 to her new employer. Use payroll software like Xero or HMRC’s Basic PAYE Tools to streamline this, and double-check all figures against your payroll records.
Quick Tips:
Accuracy is Key: Errors can lead to tax issues for Emma or penalties for you.
Submit RTI Promptly: Include the leaving date in your final RTI submission for Emma.
Keep Records: Store a copy of the P45 for at least 3 years, as HMRC may request it (source: GOV.UK Recordkeeping).
Case Study: Avoiding a P45 Mishap
Imagine you’re running Bristol Brew Ltd, and Emma’s P45 has an error—you listed her total pay as £15,000 instead of £12,000. Her new employer uses this, and she’s overtaxed £600. By catching this before submission, correcting it in your payroll software, and reissuing the P45, you save Emma a tax headache and avoid an HMRC query.
This guide should make filling out a P45 a breeze. If you’re still unsure, consider a tax accountant like Pro Tax Accountant (https://www.protaxaccountant.co.uk/) to handle it for you.
How You Can Get a P45 and Navigate Tricky Situations
Now, getting your hands on a P45 might seem straightforward, but life has a way of throwing curveballs. Maybe your employer’s dragging their feet, or you’ve lost the form, or you’re dealing with a messy job situation like redundancy or working multiple gigs. Don’t worry—we’re going to walk through exactly how to get a P45, what to do if it’s missing, and how to handle complex scenarios as a UK taxpayer or business owner in the 2024-2025 tax year. This part’s all about practical steps and real-world fixes to keep your tax situation on track.
How Do You Actually Get a P45?
Let’s start with the basics. When you leave a job—whether you quit, get laid off, or retire—your employer is legally required to give you a P45. This should happen automatically, either with your final payslip or within a few days of your last day. Most employers issue it as a paper document, but some send it electronically (check your email or employee portal). The key details—your earnings, tax paid, and tax code—are pulled from the employer’s payroll records, which they submit to HMRC via Real Time Information (RTI).
If you’re wondering about timing, HMRC guidance states employers should provide a P45 within 14 days of your departure (source: HMRC PAYE Manual). If you don’t get it, don’t just sit there—reach out to your employer’s HR or payroll team. A polite email or call usually does the trick, but we’ll cover what to do if they’re unresponsive later.
What If You Don’t Get a P45?
So, the question is: what happens if your P45 doesn’t show up? Maybe your employer’s gone bust, or they’re just disorganised. First, try contacting them directly—send an email or call, and keep a record of your request. If they’re unresponsive, you’ve got options:
Ask for a Statement of Earnings: Your employer can provide a letter or payslip summary with the same details as a P45 (earnings, tax paid, tax code). This isn’t an official P45, but your new employer or Jobcentre Plus can often use it.
Use a Starter Checklist: If you’re starting a new job without a P45, complete HMRC’s Starter Checklist (available on GOV.UK). This asks about your previous employment and helps your employer assign a temporary tax code. Be warned: this might lead to emergency tax until HMRC verifies your details.
Contact HMRC: If you’re stuck, call HMRC’s Income Tax helpline (0300 200 3300) or use your Personal Tax Account on GOV.UK. They can access your PAYE records and confirm your earnings and tax paid to your new employer.
Resolving P45 Issues
If your employer’s gone out of business, things get trickier. HMRC can sometimes retrieve your tax records, but you might need to provide payslips or bank statements as evidence. Always keep these for at least 22 months after the tax year ends, as HMRC advises (source: GOV.UK Recordkeeping).
Losing Your P45: What’s the Plan?
Be careful! Losing your P45 can cause a real headache, especially if you’re starting a new job or claiming benefits. Unfortunately, employers can’t issue a replacement P45—it’s a one-time document. But don’t panic. Here’s what you can do:
Check Part 1A: If you still have your personal copy (Part 1A), it has all the key details. Share those with your new employer or Jobcentre Plus.
Request Payroll Records: Ask your former employer for a summary of your earnings and tax paid. Most payroll systems can generate this easily.
Use HMRC’s Records: Log into your Personal Tax Account to view your employment history and tax details. You can download a “tax year overview” to share with your new employer.
Notify Your New Employer: Be upfront about the missing P45. They’ll likely use a Starter Checklist, but you can avoid emergency tax by providing as much info as possible (e.g., final payslip, tax code).
Complex Scenarios: Multiple Jobs, Redundancy, and More
Now, consider this: not every job situation is cut-and-dried. Let’s look at some trickier cases where getting or using a P45 can get complicated.
Multiple Jobs: If you’re working two jobs at once, you’ll only get a P45 from the job you leave. Your second job’s tax code might be BR (basic rate, 20%) or D0 (higher rate, 40%), as your personal allowance is usually applied to your main job. When you leave one job, the P45 helps HMRC reallocate your allowances. For 2024-2025, if your total income across jobs exceeds £50,270, you’ll hit the 40% tax band, so accurate P45 data is critical to avoid overtaxing (source: GOV.UK Income Tax Rates).
Redundancy Payments: If you’re made redundant, your P45 will include any taxable redundancy pay (over £30,000 is taxable). For example, if you receive £40,000 in redundancy pay, £10,000 is taxed at your normal rate. Check your P45 to ensure this is recorded correctly, as errors can mess up your tax code at your next job.
Temporary or Zero-Hours Contracts: If you’re on a zero-hours contract and stop getting shifts, you might not get a P45 unless you formally “leave.” Ask your employer to clarify your status and issue one if needed.
Here’s a table summarising key actions for tricky P45 situations:
Scenario | Action | Key Resource |
No P45 Issued | Contact employer; request statement of earnings | |
Lost P45 | Use Part 1A, payslips, or HMRC Personal Tax Account | |
Multiple Jobs | Provide P45 to new main employer; inform HMRC of all jobs | |
Redundancy | Check P45 for taxable redundancy pay; contact HMRC if incorrect |
Case Study: Ayesha’s Redundancy Woes
Picture this: Ayesha, a 42-year-old marketing manager from Manchester, was made redundant in November 2024. Her employer issued a P45 showing £35,000 in redundancy pay, but it incorrectly listed £5,000 as taxable instead of £0 (since it was under the £30,000 tax-free threshold). When Ayesha started a new job in January 2025, her new employer applied a tax code that assumed she’d earned more taxable income, costing her £1,000 in overpaid tax. She contacted HMRC with her redundancy agreement and P45, and they corrected her tax code, issuing a refund in March 2025. Lesson? Always double-check redundancy figures on your P45.
What Should You Do If a New Employee Doesn't Have a P45?
If you find that you are recruiting a new non-P45 staff member, complete the new HMRC Retirement Checklist. If there is no P45, the checklist will help you gather all the information you need to set up an employee in your PAYE system, including items such as:
● Personal information
● Loan obligations (including student loans)
● citizen service number
This checklist can be filled out digitally or as a printable document. Employees only need to provide this information to their employer instead of submitting the form to HMRC.
What Else Do I Need To Do When Changing Jobs?
In addition to obtaining your P45, you'll have to do a few administrative tasks prior to you starting employment. The day you start work you'll be expected by your new employer to ask for these:
● Your bank details
● A valid proof of ID Most often, it is an official driving license or a passport
● Address Details
● Your National Insurance number - if you're not sure what it is, GOV.UK offers advice on how to find it
What About a P46?
The P46 form was issued to anyone who hadn't had a job before, or who didn't possess the P45. The P46 form has been no longer in use however and is now replaced by the starter Checklist form. The Starter Checklist includes questions about the other jobs or benefits you may have. It also helps your employer determine the correct tax code prior to the time your first paycheck is sent out. If you don't have these details, you could be placed on the emergency tax code.

P45 form is an important document that is required by law in the UK. Employers are required to provide a P45 form to employees who leave their job, and the form contains important information about the employee's earnings and tax payments.

Let’s face it—tax forms like the P45 aren’t exactly thrilling reading, and mistakes can cost you. A tax accountant doesn’t just crunch numbers; they act like a tax detective, spotting errors and fixing problems before they spiral. For employees, this might mean catching an incorrect tax code on your P45 that’s led to overtaxing. For business owners, it’s about ensuring your payroll complies with HMRC rules, avoiding penalties that can reach £3,000 per employee for errors (source: HMRC Penalties for Employers).
A good accountant, like those at Pro Tax Accountant, can:
Review Your P45: Check for errors in earnings, tax paid, or tax codes.
Liaise with HMRC: Sort out issues like emergency tax or incorrect records.
Advise on Refunds: Help you claim overpaid tax quickly, using forms like P50.
Support Businesses: Ensure P45s are issued correctly and RTI submissions are accurate.
Handle Complex Cases: Deal with redundancy payments, multiple jobs, or missing P45s.
Employees: Getting Your Taxes Back on Track
Picture this: you’ve started a new job, but your P45’s missing or wrong, and your payslip shows you’re being taxed way too much. A tax accountant can step in to fix it. They’ll review your P45 against payslips and HMRC records, then contact HMRC to update your tax code. For example, if you’re on an emergency tax code (like 1257L W1), they can expedite the process to get you back to the standard 1257L code, ensuring you’re taxed correctly on your £12,570 personal allowance for 2024-2025 (source: GOV.UK Income Tax Rates).
They can also help if you’ve overpaid tax. In 2023-2024, HMRC processed over 1 million tax refunds, with an average overpayment of £300 per person (source: HMRC Annual Report 2023-2024). An accountant can file a claim via your Personal Tax Account or Form P50, often getting your refund faster than you could on your own.
Business Owners: Staying HMRC-Compliant
Right, business owners, this one’s for you. Issuing a P45 isn’t just a tick-box exercise—it’s a legal requirement under the PAYE system. A tax accountant can ensure your payroll software (like Xero or QuickBooks) generates accurate P45s, with correct earnings, tax, and National Insurance contributions. They’ll also handle Real Time Information (RTI) submissions to HMRC, which must include P45 data for departing employees. Mess this up, and you could face a compliance check from HMRC, with fines starting at £100 for late RTI submissions (source: GOV.UK RTI Guidance).
Accountants can also train your payroll team to spot common errors, like incorrect tax codes or misreported redundancy payments. For small businesses, outsourcing payroll to a firm like Pro Tax Accountant can be a game-changer, freeing you up to focus on growth while they keep HMRC happy.
Case Study: Liam’s P45 Predicament
So, let’s talk about Liam, a 39-year-old cafe owner from Bristol with a side hustle as a freelance graphic designer. In October 2024, Liam hired a part-time barista, Priya, who worked for three months before leaving for a full-time role elsewhere. Liam, new to running a business, used basic payroll software but forgot to issue Priya’s P45. Meanwhile, Priya started her new job and was hit with an emergency tax code (1257L M1), costing her £450 in overpaid tax because her new employer didn’t have her P45. Frustrated, Priya contacted Liam, who realised he’d also missed an RTI submission to HMRC, putting him at risk of a £200 fine.
Enter Pro Tax Accountant. Liam reached out to them in November 2024, desperate to fix the mess. Their team, led by a senior accountant, took the following steps:
Reviewed Payroll Records: They checked Liam’s payroll data, confirming Priya’s earnings (£6,000) and tax paid (£400) for the tax year.
Generated a Correct P45: Using Liam’s payroll software, they created an accurate P45 for Priya, including her 1257L tax code and correct National Insurance contributions.
Submitted RTI to HMRC: They filed a late RTI submission, explaining the delay to HMRC to avoid penalties.
Supported Priya: They contacted Priya’s new employer, providing the P45 and explaining her tax situation. They also helped Priya claim a £450 refund via her Personal Tax Account, processed by HMRC in December 2024.
Trained Liam: To prevent future issues, Pro Tax Accountant gave Liam a one-hour training session on PAYE compliance, including how to issue P45s and submit RTI on time.
By January 2025, Priya’s tax code was corrected, her refund was in her bank account,
and Liam’s business was back in HMRC’s good books. Pro Tax Accountant also set Liam up with a monthly payroll service to handle future employee departures, saving him hours of admin work.
Here’s a table summarising the key actions Pro Tax Accountant took for Liam and Priya:
Issue | Action Taken | Outcome |
Missing P45 | Generated accurate P45 from payroll records | Priya’s new employer updated her tax code |
Late RTI Submission | Filed RTI with explanatory note to HMRC | Avoided £200 fine for Liam’s business |
Priya’s Overpaid Tax | Assisted with refund claim via Personal Tax Account | £450 refunded to Priya in December 2024 |
Liam’s Payroll Knowledge | Provided training on PAYE and P45 processes | Liam now compliant with HMRC requirements |

Summary of All the Most Important Points
A P45 form, officially “Details of Employee Leaving Work,” records your earnings, tax paid, and tax code when you leave a UK job, ensuring accurate tax calculations for your next employer or benefits claim.
The P45 has four parts: Part 1 goes to HMRC, Part 1A is for you, and Parts 2 and 3 are for your new employer or Jobcentre Plus to prevent tax errors.
Without a P45, you risk emergency tax (e.g., 1257L W1/M1), which can overtax your income, as seen in 2023-2024 when 1.2 million UK workers overpaid £300 million in tax.
Employers must issue a P45 within 14 days of an employee leaving, and failure to do so can lead to HMRC fines of up to £3,000 per employee.
Always check your P45 for errors in earnings, tax paid, or tax code, as mistakes can lead to overtaxing or issues with your new job or benefits.
If you lose your P45, use Part 1A, payslips, or HMRC’s Personal Tax Account to provide details to your new employer and avoid emergency tax.
For multiple jobs, a P45 from the job you leave helps HMRC reallocate your £12,570 personal allowance (2024-2025) to avoid overtaxing at higher rates like 40%.
Redundancy payments over £30,000 are taxable, and your P45 must accurately reflect this to prevent tax code errors at your next job.
If your employer doesn’t issue a P45, contact them for a statement of earnings or use HMRC’s Starter Checklist to start a new job, though this may trigger temporary emergency tax.
For businesses, accurate P45 issuance and RTI submissions to HMRC are critical to avoid penalties and ensure former employees’ tax records are correct.
