If you are reading this, you likely already know that the days of financial privacy are over. Through the Common Reporting Standard (CRS), HM Revenue & Customs (HMRC) now receives automatic data from over 100 jurisdictions from Switzerland and Dubai to Spain and the British Virgin Islands. If you have an offshore account, property or crypto asset, HMRC likely already knows about it. The Disclosure Using the Worldwide Disclosure Facility (WDF) is your opportunity to fix historic mistakes before a full investigation begins.
However, the stakes have changed. Since the introduction of the Requirement to Correct (RTC) legislation, the penalties for getting this wrong can now reach 200 per cent of the tax owed.
Make a Disclosure Using the Worldwide Disclosure Facility
This guide explains exactly how to navigate the WDF process, how to calculate your penalties, and why receiving a Nudge Letter requires immediate, careful action.
If you have already received a letter from HMRC, the clock is ticking. Do not attempt to file this alone. Contact our Worldwide Disclosure Facility tax advisor immediately to protect your position.
What is the Worldwide Disclosure Facility (WDF)?
The Worldwide Disclosure Facility is a digital channel provided by HMRC that allows individuals, companies, and trustees to voluntarily disclose unpaid UK tax liabilities related to offshore matters. This includes:
- Rental income from overseas property.
- Interest or dividends from foreign bank accounts.
- Capital gains on the disposal of overseas assets (including crypto assets held on foreign exchanges).
Crucially, the WDF does not offer immunity from criminal prosecution. Unlike the Contractual Disclosure Facility (COP9), which is reserved for admitting tax fraud, the WDF is a civil settlement route. This makes it vital that you accurately classify your behaviour (e.g., as careless rather than deliberate) to avoid accidentally admitting to tax evasion.
The Nudge Letter: Why You Received It
Many clients come to us after receiving a letter from HMRC with the heading: Important: Your offshore assets, income or gains.
This is known as a Nudge Letter. It means HMRC’s Connect computer system has flagged a discrepancy between your UK tax return and the data they obtained from an overseas bank.
The letter often includes a Certificate of Tax Position. Warning: Treat this document with extreme caution.
- Do not simply tick a box and return it without professional advice.
- Making a false declaration on this certificate is a criminal offense.
- If you ignore the letter it is equally dangerous as it often prompts HMRC to open a formal civil or criminal investigation.
3 Step Disclosure Process
Step 1
Notification
First, you must notify HMRC of your intent to disclose via the Digital Disclosure Service (DDS).
You will need your National Insurance number & Unique Taxpayer Reference (UTR).
Once accepted. HMRC will issue you a Disclosure Reference Number DRN
Step 2
The 90 Day Calculation Period
This is the most critical phase. From the moment you receive your DRN, you have exactly 90 days to:
- Collate bank statements for all relevant years (sometimes up to 20 years).
- Calculate the tax owed for each year.
- Calculate the statutory interest.
- Self assess your penalty rate based on your behaviour.
Step 3
Submission & Payment
You submit the full disclosure report online.
Note: HMRC official condition is that payment must be made at the time of submission.
If you cannot pay the full lump sum immediately, you must propose a formal Time to Pay arrangement backed by evidence before you submit the disclosure.

WDF Penalty Rates 2025/26
The amount you pay depends entirely on Taxpayer Behaviour. HMRC places the burden on you to tell them how guilty you are.
| Behaviour Type | Description | Standard Penalty | Failure to Correct (FTC)* |
|---|---|---|---|
| Reasonable Excuse | Unforeseen event (e.g., serious illness). | 0% | 0% |
| Careless | You failed to take reasonable care. | 0% – 30% | N/A |
| Deliberate | You knew you owed tax but hid it. | 20% – 70% | Min 100% |
| Deliberate & Concealed | You took active steps to hide the money. | 30% – 100% | Max 200% |
Note: The Failure to Correct (FTC) penalties apply specifically to liabilities that existed before April 2017. These penalties are draconian and start at 100%.
How Many Years Back Can HMRC Go?
The Lookback Period determines how many years of tax you must pay.
- 4 Years: Genuine mistake despite reasonable care.
- 6 Years: Careless behaviour (the most common settlement ground).
- 12 Years: Offshore non-compliance (specific rule).
- 20 Years: Deliberate tax evasion.
Strategic Note: We frequently see clients assume they must disclose 20 years. By correctly applying the statute of limitations, we can often legally restrict the disclosure to just 6 years, removing older liabilities entirely.
Common Mistakes to Avoid
Filing a WDF disclosure yourself (DIY) is risky. Here are the most common errors we fix:
- Ignoring Foreign Tax Credits: If you paid tax on the income in the foreign country (e.g., US withholding tax), you can offset this against your UK bill. Many people miss this and pay tax twice.
- The Connected Error: If you have previously made an inaccurate disclosure, you are subject to higher penalties. Do not try to sneak a second disclosure through without referencing the first.
- Missing Assets: Forgetting a dormant account or a crypto wallet. If HMRC finds you omitted something from your disclosure, they view it as a criminal attempt to defraud.
