How to Make a Capital Gains Disclosure to HMRC in the UK?


Understanding Capital Gains Tax Disclosure

Capital Gains Tax (CGT) is a tax on the profit made when you sell, or 'dispose of', an asset that has increased in value. In the UK, it's important to understand the requirements for disclosing these gains to HM Revenue and Customs (HMRC) to ensure compliance and avoid penalties. This article will guide you through the process, specifically tailored for UK and non-UK taxpayers dealing with UK assets.


How to Make a Capital Gains Disclosure to HMRC in the UK

1. When to Report and Pay CGT

The rules for reporting and paying CGT in the UK vary based on the type of asset sold and your residency status.

  • For Residential Property (Post-April 2020): If you sold a UK residential property on or after 6 April 2020, you must report and pay any CGT due within 60 days of the sale if the completion date was on or after 27 October 2021. For sales between 6 April 2020 and 26 October 2021, the window was 30 days​.

  • For Other Assets: If your capital gain is not from a residential property sold after 6 April 2020, you can report it either in a Self Assessment tax return or using the 'real time' Capital Gains Tax Service​.


2. Preparing for CGT Disclosure

Before reporting your gains, it's essential to gather the necessary information:

  • Details Required: This includes the purchase and sale prices of the asset, dates of ownership, and other relevant details like costs related to buying, selling, or improving the asset. Tax reliefs, allowances, or exemptions you're entitled to claim should also be prepared​.

  • Non-UK Residents: If you're not a UK resident but have sold UK property or land on or after 6 April 2020, you must report all sales and disposals of UK property or land by the deadline, even if no tax is due​​​.


3. Reporting CGT: Online and Paper Forms

The method of reporting depends on various factors, including the type of asset and your ability to access online services.

  • Online Reporting: Use a Capital Gains Tax on UK property account to report and pay tax on UK property. You’ll need a Government Gateway user ID and password to set up or access your account​.

  • Paper Reporting: If you cannot report online, download and fill in a paper form or ask HMRC for a paper form if you can't access the internet​.


4. Special Cases

  • Jointly Owned Properties: Each co-owner must report their gain or loss individually. Special rules apply if you give a UK property to your spouse, civil partner, or to charity​.

  • Reporting on Behalf of Others: If you're reporting on behalf of someone else or an estate, you'll need proof of authority, like lasting power of attorney or proof of executorship in case of death​.

Understanding the basic requirements for CGT disclosure is crucial for compliance with UK tax laws. This includes knowing when and how to report, what details are needed, and the specific rules for different types of assets and residency statuses. In the next part, we will delve into the specifics of calculating CGT and understanding exemptions and reliefs.

Calculating Capital Gains and Understanding Exemptions


1. Calculating Capital Gains

Understanding how to calculate your capital gain or loss is crucial for accurate disclosure. The basic formula involves subtracting the purchase price of the asset from the sale price. However, several adjustments must be considered:

  • Inclusion of Associated Costs: Include costs associated with buying, selling, or improving the asset. These could be fees for legal services, estate agents, and costs of any improvements made to increase the value of the asset.

  • Date of Ownership and Disposal: The dates when you acquired and disposed of the asset are important, as they may affect the calculation of the gain or loss.

  • Property Specifics: For property sales, include the address and postcode, date of exchange of contracts, completion date, and property values at acquisition and disposal.


2. Exemptions and Reliefs

Several exemptions and reliefs can reduce the CGT liability:

  • Annual Exempt Amount: Each individual has a tax-free allowance for capital gains. If your total gains are below this threshold, you may not need to report them.

  • Private Residence Relief: If the property sold was your main home, you might be eligible for Private Residence Relief, which can significantly reduce or eliminate CGT.

  • Letting Relief: If you let out part of your home, Letting Relief could apply, potentially reducing the CGT due.

  • Gifts to Spouses or Civil Partners: Transfers between spouses or civil partners are usually exempt from CGT, but subsequent disposal by the receiving partner will consider the entire period of ownership.


3. Reporting for Non-UK Residents

For non-UK residents, the reporting requirements differ:

  • All UK Property Sales Must Be Reported: Regardless of whether there is a tax liability, all disposals of UK property or land must be reported.

  • Non-Resident CGT Return: If you sold UK property or land before 6 April 2020, a non-resident CGT return is required.


4. Special Reporting Cases

  • Joint Ownership: For jointly owned properties, each owner must report based on their share of the gain.

  • Estates and Deceased Persons: In the case of deceased individuals, the estate’s executor must report the gain or loss. Special rules apply here, and professional advice may be beneficial.


Calculating capital gains accurately is a critical step in CGT disclosure. Understanding exemptions and reliefs can significantly affect the amount of tax owed. Additionally, special rules for non-UK residents and different types of ownership must be carefully considered. In the next part, we will explore the nuances of paying CGT, timelines for payment, and consequences of non-compliance.


Paying Capital Gains Tax, Timelines, and Non-Compliance Consequences


1. Paying Capital Gains Tax

Once you've calculated your capital gains and reported them to HMRC, the next step is paying any tax due. The process varies slightly depending on the method of reporting:

  • Online Reporting: After reporting your gains through the HMRC portal, you'll receive a 14-character payment reference number, starting with 'X', which you must use to make your payment within the specified deadline​.

  • Paying via 'Real Time' Capital Gains Tax Service: For gains reported through the real-time service, HMRC will send a letter or email with a payment reference number. Payment methods include the online tax payment service, online banking, or cheque​.

  • Payment Deadlines: It's critical to adhere to payment deadlines to avoid interest and penalties. For gains on property, the deadline is either 30 or 60 days post-sale, depending on the date of sale​​. For other gains, you must report by 31 December in the tax year after you made your gain and pay by 31 January of the following year​.


2. Reporting and Paying for Non-UK Residents

Non-UK residents have specific requirements:

  • Mandatory Reporting: All disposals of UK property or land must be reported, regardless of tax liability​.

  • Non-Resident Capital Gains Tax Return: For sales before 6 April 2020, a specific non-resident return is needed​.


3. Making Amendments

If you need to make changes to a reported gain or loss:

  • Online Amendments: You can use your HMRC account to view and change your previous returns​.

  • Paper Amendments: For changes to a return made for someone else, download and fill in a paper form​.

  • Time Restrictions on Amendments: Note that some restrictions apply to amending returns from previous tax years.

4. Consequences of Non-Compliance

Failing to report and pay CGT correctly can lead to significant consequences:

  • Interest and Penalties: Late reporting and payment can result in interest charges and penalties, increasing your overall tax liability.

  • HMRC Enquiries and Investigations: HMRC may conduct enquiries or investigations into your tax affairs if discrepancies or non-compliance are suspected.

Conclusion Successfully making a Capital Gains Disclosure to HMRC involves understanding the process of calculating, reporting, and paying your CGT. It's crucial to adhere to deadlines and ensure accuracy in your disclosure to avoid penalties and interest. For both UK and non-UK residents, compliance with these regulations is key to managing your tax obligations effectively. Whether dealing with property sales or other asset disposals, being informed and proactive in your tax affairs will ensure a smooth and compliant process.


How Does HMRC Find Out About Capital Gains in the UK?


HMRC, the UK's tax, payments, and customs authority, employs various methods and sources of information to identify capital gains made by taxpayers. Understanding how HMRC detects these gains is crucial for compliance and transparency in tax matters. This article explores the mechanisms HMRC uses to track capital gains, emphasizing the importance of accurate self-reporting and the consequences of non-disclosure.

Data from Financial Institutions and Asset Managers 

HMRC has access to extensive financial data from various sources. Banks, investment firms, and asset management companies are legally obliged to report certain information to HMRC. This includes details about significant transactions, such as the sale of shares or property, that could potentially result in a capital gain. HMRC's sophisticated data-matching systems can then cross-reference this information with individuals' tax records to identify discrepancies or unreported gains.

Land Registry and Property Transaction Records 

For property transactions, HMRC utilizes data from the Land Registry. Every property sale in the UK is recorded, including details of the seller, buyer, and transaction value. HMRC can compare this data against individuals' tax records to check if capital gains tax (CGT) has been reported on property sales. This is particularly relevant since the introduction of more stringent reporting requirements for property sales post-April 2020.

Information from Legal and Financial Advisors 

HMRC also receives information from solicitors, accountants, and financial advisors involved in significant transactions. These professionals have a duty to maintain transparency in their clients’ financial affairs, and certain transactions may be flagged to HMRC as part of regulatory compliance. This collaborative approach helps HMRC track large or unusual transactions that may result in a capital gain.

International Cooperation and Information Exchange 

In an increasingly globalized world, HMRC collaborates with international tax authorities to exchange financial information. This cooperation is facilitated through agreements like the Common Reporting Standard (CRS), which allows the sharing of information about assets and incomes across borders. Consequently, capital gains realized on foreign assets by UK residents are less likely to go unnoticed.

Public Records and Open Data 

HMRC also uses public records and open-source data to identify potential capital gains. This can include information from company registers, public announcements of business sales, and even social media posts that might indicate significant financial transactions. In today's digital age, the trail of online information can often lead to the discovery of unreported gains.

Connect System and Advanced Analytics 

At the heart of HMRC's investigative capabilities is the Connect system – a sophisticated analytical tool that processes vast amounts of data from diverse sources to detect non-compliance and tax evasion. Connect cross-references and analyzes data from government and public sources, identifying patterns and anomalies that suggest undeclared income or gains.

Self-Assessment and Reporting by Individuals 

Despite these mechanisms, the cornerstone of HMRC's approach to identifying capital gains is still the self-assessment tax return. Individuals and entities are expected to declare any capital gains as part of their annual tax filings. HMRC relies heavily on this self-reporting system, with its various detection methods serving as a backup to catch non-compliance.

Consequences of Non-Disclosure 

If HMRC discovers a capital gain that has not been reported, the consequences can be significant. This can include not only the payment of the tax owed but also potential penalties and interest charges. In serious cases, this could lead to prosecution and criminal charges for tax evasion.

Conclusion HMRC employs a multifaceted approach to identify capital gains, leveraging data from financial institutions, property records, legal and financial advisors, international partnerships, public records, and advanced analytics. While the UK relies on a self-assessment system, HMRC's robust detection mechanisms underscore the importance of accurate and timely reporting of capital gains. Compliance ensures fairness and contributes to the integrity of the UK's tax system.


What Can Be the Consequences if HMRC Find Outs About Non-Paid And Overdue Capital Gains Tax In The UK

What Can Be the Consequences if HMRC Find Outs About Non-Paid And Overdue Capital Gains Tax In The UK?

When HM Revenue and Customs (HMRC) in the UK discovers unpaid and overdue Capital Gains Tax (CGT), the consequences for the taxpayer can be significant and far-reaching. Understanding these consequences is vital for anyone involved in transactions that may result in capital gains. This article delves into the potential repercussions of non-compliance with CGT obligations, highlighting the importance of adhering to tax laws and regulations in the UK.


1. Interest on Late Payments

One of the immediate consequences of not paying CGT on time is the accrual of interest. HMRC charges interest on overdue tax from the date the payment was due until the date it is paid. This interest is calculated on a daily basis, which can substantially increase the total amount owed if the payment is delayed for a significant period.


2. Penalties for Late Disclosure

In addition to interest, taxpayers may face penalties for failing to report capital gains in a timely manner. HMRC imposes penalties based on the period of delay and the taxpayer’s behavior. These penalties are categorized as:

  • Failure to Notify: If you don’t report the capital gain on time, HMRC can impose a penalty. This penalty can be a percentage of the tax owed, depending on how late the disclosure and payment are.

  • Inaccuracy Penalty: If you submit an inaccurate return that understates your liability, HMRC can impose a penalty. The level of this penalty depends on whether HMRC believes the error was due to carelessness, deliberate understatement, or deliberate and concealed understatement.


3. Additional Consequences for Understated Returns

If HMRC finds that a taxpayer has deliberately understated their capital gains, the consequences become more severe. This can include:

  • Higher Penalties: Deliberate understatement of tax liabilities can result in higher penalties, which can be up to 100% of the unpaid tax for domestic matters and up to 200% for offshore-related matters.

  • Publication of Details: In cases of significant underpayment due to deliberate behavior, HMRC has the authority to publish the details of the defaulter. This ‘name and shame’ approach is intended as a deterrent and can have reputational consequences for the individual or business involved.


4. Consequences of Persistent Non-Compliance

For taxpayers who repeatedly fail to comply with their CGT obligations, HMRC can take more stringent actions, such as:

  • Surcharge on Additional Assessments: Additional surcharges can be levied on tax assessments made as a result of an HMRC enquiry into a taxpayer’s affairs.

  • Asset Seizure: In extreme cases, HMRC has the authority to seize assets to recover unpaid taxes.


5. Impact on Credit Rating

Unpaid taxes, including CGT, can affect an individual’s credit rating. This could have long-term implications for obtaining loans or mortgages, as financial institutions often review credit histories for indications of financial reliability.


6. Legal Proceedings and Prosecution

While HMRC usually resorts to penalties and fines as the first course of action, in cases of significant or fraudulent non-compliance, legal proceedings may be initiated. This could lead to prosecution, with potential outcomes including substantial fines or even imprisonment.


7. Investigation Costs

Taxpayers under investigation for non-compliance may incur significant costs. This includes legal fees, accounting fees, and other costs associated with the investigation and defense process. These costs can be substantial, adding a financial burden on top of the tax owed, interest, and penalties.


8. Impact on Business Operations

For businesses, the discovery of unpaid CGT can have operational implications. It can trigger a more comprehensive audit of the business’s tax affairs, potentially disrupting normal business activities. The reputational damage from non-compliance can also affect business relationships and future opportunities.


The consequences of not paying overdue Capital Gains Tax in the UK can be extensive, ranging from financial penalties and interest to legal repercussions and reputational damage. It is crucial for taxpayers to be aware of their CGT obligations and to comply proactively. Timely disclosure and payment of taxes not only avoid these consequences but also ensure that taxpayers maintain a good standing with HMRC, safeguarding their financial and professional integrity.

Navigating the Capital Gains Disclosure Process for Trustees and Estates

Introduction to Capital Gains for Trustees and Estates Capital Gains Tax (CGT) implications for trustees and estates, particularly for those involving UK rental income, require careful navigation to ensure compliance with HMRC regulations. This section is designed to guide trustees, especially non-resident trustees, through the process of applying for UK rental income without tax deductions and the associated CGT disclosure obligations.


1. Application Process for Non-Resident Trustees


  • Online Service or Postal Form: Non-resident trustees can apply to receive UK rental income without tax deductions either through an online service or by using a postal form​​​.

  • Government Gateway ID: To apply online, trustees need a Government Gateway user ID and password. If they don’t have a user ID, they can create one during the application process​.

  • Postal Form Requirements: The postal form must be used by agents or those who cannot access the online service. It’s important to fill in the form completely before printing, as partially completed forms cannot be saved​​​.


2. Authorising an Agent

  • Form 64-8: Trustees can authorise an agent, such as an accountant or tax adviser, to handle their tax affairs by completing the 'Authorising your agent (64-8)' form​​​.

  • Scope of Authorisation: This form allows the agent to handle various tax-related tasks, including submitting tax returns, discussing tax matters, and updating HMRC with relevant information​.


3. Responsibilities and Limitations of Agents

  • Self Assessment Responsibilities: Trustees remain responsible for their own tax affairs, even when an agent is authorised. They must check the information provided by the agent before submission​.

  • Trusts and Corporation Tax: Authorisation for trusts allows the agent to access personal and financial information of the trust, but it does not provide access to the Trust Registration Service​​​.

4. Authorising a Friend, Relative, or Intermediary

  • Trusted Helper: Trustees can appoint a trusted helper, like a friend or family member, to manage their tax online. This helper can perform tasks like checking Income Tax amounts and updating personal tax accounts​.

  • Intermediaries: For trustees with special needs, such as illness or language barriers, an intermediary can be authorised to deal with HMRC. The intermediary can assist in communication and form-filling but won't have access to online tax accounts​.


5. Power of Attorney and Tax Affairs

  • Lasting Power of Attorney (LPA): Trustees can set up an LPA, allowing someone to make tax decisions on their behalf. The details of the LPA must be communicated to HMRC, along with a certified copy of the power of attorney document.

For trustees, especially those living outside the UK, understanding the process of applying for UK rental income without tax deductions is crucial. This involves choosing between online and postal applications, authorising agents or trusted helpers, and considering the option of setting up an LPA. The next part will explore the specifics of Self Assessment for trustees and estates, including deadlines, record-keeping requirements, and payment processes.


Understanding Your Capital Gains Disclosure Period

1. Determining the Disclosure Duration 

The number of years you need to disclose your income or gains to HMRC depends on when you first realized you should have informed them. Here's how to figure it out:

  • Voluntary Disclosure: If you're voluntarily disclosing, think about why you didn't inform HMRC earlier. Was it a simple mistake, carelessness, or a deliberate act? Or, was it related to offshore matters that are harder for HMRC to detect? Your payment will vary based on these factors.


2. If You Missed Notifying HMRC about Starting a Business

  • For Individuals and Partnerships: Inform HMRC by 5 October in your business’s second tax year. For example, if you owe tax for the year ending 5 April 2023, tell HMRC by 5 October 2023.

  • For Limited Companies: HMRC usually sends a CT41G form after registering with Companies House. If you don't receive this, still inform HMRC within 3 months of starting business activities. The best way is through HMRC’s online service.

  • Missed Self Assessment Registration: If you didn't register for Self Assessment by the deadline, you might owe HMRC for up to 20 years.


3. If You Took Reasonable Care

  • Four-Year Window: If you were careful but still underpaid, you need to pay for a maximum of 4 years. Ensure your current and future tax affairs are accurate and report the previous year's affairs by the deadline. Then, complete the disclosure form for the 3 years before this.


4. If You Were Careless

  • Six-Year Window: For carelessness, you owe HMRC for up to 6 years. Ensure your tax affairs are accurate for the current and future years and report the previous year's affairs. Fill in the disclosure form for the 5 years before this.


5. If You Deliberately Misled HMRC

  • Twenty-Year Window: If you knowingly underpaid tax, you owe for up to 20 years. This applies if you intentionally didn't disclose income or submitted incorrect tax returns.


6. Offshore Matters

  • Offshore Matters Timeline: The timeframe for offshore-related inaccuracies depends on the nature of the income. For cases involving reasonable care, the window is 12 years from the end of the relevant period, starting from the 2015-2016 tax year. For careless behavior, it starts from the 2013-2014 tax year.


7. Inheritance Tax

  • Inheritance Tax Disclosure: If you haven't submitted an Inheritance Tax return and paid the tax, you need to settle what you owe for the past 20 years. If you deliberately avoided paying Inheritance Tax, there’s no time limit; you must pay back all the owed tax.


Getting Your Disclosure Ready for HMRC: A Step-by-Step Guide

Hey folks! Today, I'm here to help you understand how to prepare your disclosure for HMRC. Whether you're an individual or a business, this can be a bit tricky, so let's break it down into simpler steps.


1. Start Early and Get Organized

  • 90-Day Window: You have 90 days from when HMRC acknowledges your notification to make your disclosure. But hey, why wait? Start gathering your info and records as soon as you can.

  • Focus on Unreported Income: You only need to include income in your disclosure that you haven’t already declared to HMRC. No need to worry about the income where tax has already been paid.


2. Calculating Your Tax Owed

  • Do the Math: Work out the additional liabilities for each year you got it wrong. Remember to factor in any PAYE income or other income you've already told HMRC about.

  • Consider Your Income Tax Rates: The amount of Income Tax you owe depends on your earnings above your Personal Allowance (the amount you can earn tax-free each year).

  • Payments on Account: If you make these, include them in your calculations.

  • Using Tools: HMRC has tools to help you figure out interest and penalties for up to 20 years. You’ll need to calculate each year's tax liability before using these tools.


3. Special Situations

  • Tax Credits: If you or your partner are getting tax credits, still make a disclosure and tick the relevant box. HMRC will adjust your tax credits accordingly.

  • Companies and Organizations: You need to figure out the Corporation Tax on any undeclared income. This might also mean updating your records with Companies House.


4. Incomplete Records? No Problem!

  • Estimations: If your records aren't complete, estimate your undisclosed income and gains. Just be ready to explain your estimates to HMRC.

  • Bank Statements: These are important. If you can't get them, use recent statements as a guide and explain why you couldn’t obtain the older ones.

  • Record-Keeping: Start keeping proper business records now. Not doing so could result in a penalty of up to £3,000.


5. What Income to Include in Your Disclosure

  • Exclude Current and Last Year’s Income: Income from the current tax year or the year before should be handled differently. For current year income, you’ll need to register for Self Assessment (or Corporation Tax for companies) and report this income on your next tax return.

  • Tax Returns for Prior Years: Usually, you need to file tax returns by 31 October for paper returns and 31 January for online returns. If you’ve missed including some income, you can amend last year’s tax return within 12 months of the filing date.

  • Company Tax Returns: These should be filed within 12 months from the end of your accounting period. If you have outstanding returns, file them for the past 4 years and include earlier income in your disclosure.

So, there you have it – your straightforward guide to preparing your disclosure for HMRC. Remember, getting professional advice can be really helpful, especially if things seem complex. And don’t forget, keeping good records moving forward is key to avoiding these issues in the future. Stay informed and stay on top of your taxes!

10. Making a Disclosure for Someone Who’s Passed Away

  • Dealing with Deceased's Taxes: If you’re managing taxes for someone who’s died, you can make a disclosure on their behalf using HMRC’s digital service. Just make sure to indicate that you’re acting for them.


11. Your Rights and HMRC's Expectations
