The Worldwide Disclosure Facility (WDF) is the route HMRC provides for taxpayers to correct an offshore tax position voluntarily. For crypto holders it is the mechanism that matters most: assets held on exchanges incorporated outside the UK, on offshore custodians, or in structures based overseas fall within its scope, and unprompted disclosure carries materially lower penalties than one made after HMRC opens an enquiry.
When crypto falls within the Worldwide Disclosure Facility
An offshore matter arises where income or gains arise outside the UK, where assets are situated or held outside the UK, or where activities are carried on outside the UK. Most crypto positions meet at least one of those tests. If your disposals were executed on an exchange incorporated abroad, or your holdings sat with a non-UK custodian, the offshore penalty regime applies and the WDF is the correct disclosure channel.
Purely domestic omissions are corrected through HMRC's Digital Disclosure Service instead. Part of our first assessment is establishing which route applies, because using the wrong one delays the correction and can affect the penalty outcome.
Why the penalty position is the whole game
Offshore penalties are charged at significantly higher rates than domestic ones, and they are geared to the behaviour behind the error and to the territory involved. The difference between a careless error disclosed unprompted and a deliberate one uncovered by HMRC is the difference between a manageable settlement and a life-changing one.
Disclosure also runs against the clock. HMRC receives exchange data through the Crypto-Asset Reporting Framework and existing international exchange-of-information agreements. Disclosing before HMRC contacts you preserves the unprompted reduction; disclosing afterwards does not.
What we do
- Reconstruct the full transaction history across every exchange, wallet and chain, including exchanges that no longer exist or no longer provide exports.
- Compute the correct UK position for each year: Section 104 pooling, the same-day and 30-day rules, income versus capital treatment for staking, mining, lending and airdrops.
- Establish the behaviour category and quantify the number of years that must be disclosed, which ranges from four to twenty depending on that assessment.
- Register the disclosure, prepare the report and supporting computations, and submit it within HMRC's deadline.
- Handle correspondence, penalty negotiation and any follow-up enquiry through to closure, and agree a payment arrangement if needed.
Who this is for
This service is built for holders with substantial undeclared positions, multi-year histories, or exposure across several jurisdictions. If you have a single year of modest gains and complete records, an amended return is usually the cheaper and faster fix, and we will tell you so at the first call rather than sell you a disclosure you do not need.
