HMRC Worldwide Disclosure Facility

UK residents in receipt of foreign incomes and gains must either report and tax the incomes and gains or claim special tax status (currently FIG regime and historically remittance basis).

If you have forgotten to declare the foreign incomes and gains or claim special tax status, the Worldwide Disclosure Facility (WDF) offers a formal process to bring your affairs up to date with HMRC.

This guide provides a comprehensive overview of the WDF, explaining why it exists, how the process works, and how Global Tax Consulting can help you navigate this transition smoothly.

The Obligation to Report: A Critical Disclaimer

A common misconception among UK residents with international interests is that paying tax in a foreign country exempts them from UK reporting. It is important to note that just because your income was taxed overseas, this does not remove your reporting obligation to HMRC.

However, providing that you have already paid tax on that income in another jurisdiction, you may be able to take that tax paid into account by claiming a Foreign Tax Credit (FTC) which reduces your UK tax liability.

Nevertheless, the reporting requirement remains mandatory. Failure to disclose the income: even if no additional tax is eventually due: can still result in penalties for non-disclosure.

Why HMRC Will Eventually Find Out: The Common Reporting Standard (CRS)

In the current digital age, the "wait and see" approach to offshore tax is increasingly risky. This is due to the Common Reporting Standard (CRS), an international agreement signed by over 100 countries to automatically share financial data. Under this agreement, foreign banks, investment firms, and insurance companies report information about accounts held by non-residents to their local tax authorities, who then share it with HMRC.

The data shared through the CRS includes:

• Bank account balances and interest earned.
• Dividends and sales proceeds from financial assets.
• The identity of the account holder and their tax residency.
  ‍

HMRC now possesses one of the most sophisticated data-matching systems in the world. With respect to offshore assets, it is no longer a matter of "if" HMRC will find out about your undeclared foreign income, but "when."

Receiving a "nudge letter" from HMRC: which suggests they already have information about your overseas interests: significantly reduces your ability to mitigate penalties.

What is the Worldwide Disclosure Facility (WDF)?

The Worldwide Disclosure Facility is the specific mechanism established by HMRC to allow individuals and businesses to bring their tax affairs up to date regarding undeclared foreign income and gains. It is part of the Digital Disclosure Service (DDS) and is specifically designed for "offshore" issues.

An offshore issue includes:

• Income arising from a source outside the UK.
• Assets situated or held outside the UK.
• Activities carried out wholly or mainly outside the UK.
• Funds or assets transferred outside the UK.

Using the WDF allows you to disclose any unpaid tax liabilities from previous years in a structured, transparent manner.

The 5-Step Process: How the WDF Works

The WDF follows a strict, time-bound procedure. If you intend to use this facility, you must be prepared to act quickly once the process begins.

1. Make a Notification

The first step is to notify HMRC that you intend to make a disclosure. This is done through the Digital Disclosure Service. Once you have notified HMRC, they will issue you a Disclosure Reference Number (DRN). You can make a notification to HMRC that you intend to make a disclosure here.

2. Gather Records and Complete Calculations

Once you have notified HMRC, you have a 90-day window to submit the full disclosure. During this period, you must gather all relevant financial records from previous years. This includes bank statements, property sale documents, and dividend vouchers. You must then calculate the exact amount of tax owed, plus interest (calculated from the date the tax was originally due) and the appropriate penalties.

3. Prepare the Disclosure

After completing the calculations, you must prepare the formal disclosure. This involves detailing the nature of the income, the years it relates to, and an explanation of why the income was not declared at the time. This "narrative" is a critical part of the process, as it helps HMRC understand your "behaviour": a key factor in determining penalty levels.

4. Pay What You Owe

At the time of submitting the disclosure, you are expected to pay the full amount of tax, interest, and penalties you have calculated. Providing that you cannot pay the full amount immediately, you must approach HMRC to discuss a payment plan before the 90-day deadline expires. Payment is typically made via bank transfer using your Payment Reference Number.

5. Wait for the Seal of Approval

After submission, HMRC will review your disclosure. They may ask follow-up questions or request documentation to verify your calculations. Once they are satisfied that the disclosure is complete and accurate, they will issue a formal acceptance letter. This provides the "seal of approval" that your tax affairs are now up to date, giving you peace of mind and protection from further investigation regarding those specific years.

Penalties and Mitigation: Understanding "Behaviour"

The level of penalties applied through the WDF is not fixed. Instead, they depend on three primary factors: the type of income, the jurisdiction where the income was sourced, and your "behaviour" as a taxpayer. HMRC categorises behaviour into three main levels:
‍

• Reasonable Care: You made a mistake despite trying your best to follow the rules. In some cases, penalties can be 0%.
• Careless: You failed to take reasonable care to get your tax right, but it wasn't a deliberate choice to hide income. Penalties here are higher but can be significantly reduced if the disclosure is voluntary.
• Deliberate: You knew you should have declared the income but chose not to. These carry the highest penalties and, in extreme cases, can lead to criminal prosecution if not disclosed voluntarily.

Furthermore, the "territory" of the income matters. Countries are grouped into three categories (Category 1, 2, and 3) based on how much information they share with the UK. Income from Category 3 countries (those with the least transparency) naturally attracts higher penalties.

The Benefits of Coming Forward Voluntarily

It is always better to approach HMRC before they approach you. There are three primary benefits to making a voluntary disclosure via the WDF:
‍

1. Reduced Penalties: Unprompted disclosures attract much lower penalty percentages than those initiated after an HMRC investigation has begun.
2. Removal of Investigation Threat: By providing a full and honest disclosure, you effectively close the door on a deep-dive tax investigation, which can be intrusive, time-consuming, and significantly more expensive.
3. Stress Reduction: Many expats live with the background anxiety of "the letter from HMRC." Completing the WDF process removes this weight and ensures that your UK residency remains on a firm legal and financial footing.
