Who it covers
Do you need to use the Worldwide Disclosure Facility?
If you are a UK taxpayer with undeclared income, gains or assets held overseas, the WDF is the route HMRC expects you to use to bring your affairs up to date.
You have undeclared foreign income
If you are a UK taxpayer receiving income from overseas sources, it usually needs declaring to HMRC. That includes:
Rental income from overseas property
Interest from foreign bank accounts
Dividends from overseas investments
Foreign employment income
Even where tax has already been paid overseas, the income still has to be reported in the UK.
You have undeclared foreign gains
Overseas capital gains are within the scope of UK tax too, and may need disclosing through the WDF. Common examples:
Selling an overseas property
Disposing of foreign shares or investments
Cryptocurrency held on offshore exchanges
Failing to declare these gains can lead to penalties if HMRC later identifies the omission.
You have received an HMRC nudge letter
Many people start the disclosure process after a nudge letter lands. HMRC sends these when it believes you may have undeclared offshore income or assets, encouraging you to review your affairs and disclose if necessary.
They are not an accusation, and they are not a formal enquiry — but they do mean you are already on HMRC’s radar, and the window to act on your own terms is open now rather than indefinitely.
Ignoring a nudge letter increases the risk of higher penalties if HMRC goes on to open a formal investigation.

I’m lucky I found Emma – she’s helped me get on top of my taxes and navigate a disclosure. She really knows her figures – even the HMRC even bowed to her knowledge and told us she was right and they were wrong.

I needed help with a fairly complex tax disclosure covering the previous 3–4 years, relating to properties in Prague that I jointly own. … Her knowledge and attention to detail gave me confidence that everything was being handled correctly.

I got into a bit of a mess especially when it comes to dealing with foreign earnings. Last year I discovered Global Tax Consulting to be the answer to this annual chore. Emma dealt with all issues speedily and effectively including rapport with the tax office.

FAQs
Questions we get every week about HMRC disclosures
Who can help me make a disclosure through HMRC’s Worldwide Disclosure Facility?
You can make a Worldwide Disclosure Facility disclosure yourself, or appoint a tax adviser to do it for you. An adviser notifies HMRC through the Digital Disclosure Service, you sign form COMP1a so HMRC can deal with them, and they then have 90 days to work out the tax, interest and penalty and submit the disclosure. Global Tax Consulting does this for people with undeclared foreign income or gains. Founder Emma McDermott ATT, formerly of Deloitte, prepares and submits every disclosure, for a fixed fee that typically ranges from £5,000 to £15,000. If HMRC has already opened an investigation or the behaviour was deliberate, you may also need a tax investigation specialist or solicitor.
What is the Worldwide Disclosure Facility?
HMRC's route for disclosing undeclared offshore income, gains, assets or accounts. You register through the Digital Disclosure Service, then have 90 days to submit a full disclosure and make an offer covering the tax, interest and penalties.
Does the WDF come with reduced penalties?
You can reduce penalties if you come forward on an unprompted basis and if you submit a quality disclosure with HMRC.
How far back does HMRC go on offshore matters?
Further than for domestic ones. Assessment windows for offshore income and gains extend to twelve years in many cases, and up to twenty where behaviour was deliberate. This is one of the main reasons offshore disclosures are worth getting right first time.
Will HMRC find out anyway?
Very probably. Over a hundred jurisdictions exchange financial account information with HMRC automatically each year, covering balances, interest, dividends and sale proceeds. The practical question is usually not whether HMRC learns about an account, but whether you got there first.
I have already paid tax abroad. Do I still need to disclose?
If you are UK tax resident, foreign income and gains generally need reporting here even where tax has been paid overseas. Double tax relief then credits what you have already paid — but the relief has to be claimed, and it cannot be claimed on income that was never declared.
What about cryptocurrency held on offshore exchanges?
Disposals of crypto can give rise to UK capital gains regardless of where the exchange is based, and exchanges are increasingly within international reporting frameworks. Undeclared crypto gains are squarely within scope.
Is this confidential?
Entirely. Conversations with us are confidential, and nothing is submitted to HMRC until you have seen the numbers and agreed the approach.
