The Worldwide Disclosure Facility is HMRC's working voluntary-disclosure route for offshore tax positions. For UK landlords with overseas rental property, foreign holiday lets, offshore-held UK property, or any other offshore income, gains or assets that have not been correctly declared, the WDF is the route. It carries a 90-day disclosure timeline, operates within the ordinary Schedule 24 FA 2007 and Schedule 41 FA 2008 penalty frameworks (with offshore Category 2 and 3 uplifts where applicable), and is overlaid by the Failure-to-Correct regime under Schedule 18 Finance Act 2017 for pre-30-September-2018 offshore non-compliance.
This page walks the WDF mechanic, the FtC overlay and its 200 per cent post-deadline penalty floor, the section 36A FA 2019 12-year discovery window that defines the years in scope for offshore innocent-error cases, the territory-categorisation framework under Schedule 24 paragraph 4A, the Schedule 21 FA 2015 asset-move uplift, and two worked landlord scenarios.
What WDF covers
The WDF is broader than the Let Property Campaign in scope. It covers any UK tax position connected to offshore income, gains or assets, including:
- Offshore rental income (residential or commercial).
- Foreign holiday let income.
- Capital gains on offshore property disposals.
- Income from offshore investments (interest, dividends, bond yields, fund distributions).
- Foreign-trust income and distributions.
- Offshore-held UK assets (where the holding structure has UK-tax consequences).
- Foreign employment and self-employment income with a UK-tax residual position.
The WDF is the default offshore-disclosure route for landlord-adjacent matters. The two cases where it is not the right route are: (i) deliberate fraud with criminal-prosecution exposure (use CoP9 / CDF); and (ii) UK-only matters with no offshore element (use the Let Property Campaign for UK rental or the Digital Disclosure Service for other UK matters).
The Failure-to-Correct overlay
Schedule 18 of the Finance Act 2017 introduced the Failure-to-Correct regime as a one-off statutory window for taxpayers to correct historic offshore tax non-compliance. The deadline was 30 September 2018. Post-deadline, offshore tax non-compliance that existed at 30 September 2018 attracts the FtC penalty framework:
- Base FtC penalty: 200 per cent of the tax involved (Schedule 18 paragraph 4).
- Reduction for full unprompted disclosure: down to 100 per cent.
- Reduction for full prompted disclosure: down to 150 per cent (depending on quality).
- Asset-based penalty: additional penalty under paragraph 7 in cases involving substantial assets, up to 10 per cent of the value of the offshore asset.
- Naming-and-shaming: HMRC publication of taxpayer details in serious cases under paragraph 11.
The FtC deadline was not extended. Commentary suggesting otherwise is wrong. Any offshore tax non-compliance that existed at 30 September 2018 and was not corrected by that date sits within the FtC framework regardless of how subsequent disclosure is made.
Critically: FtC applies to pre-existing offshore non-compliance. Offshore matters that arose after 30 September 2018 are within the ordinary Schedule 24 / Schedule 41 regime with paragraph 4A territory uplifts, not within FtC. The temporal cut-off is what each tax year's offshore position looked like as at 30 September 2018: under-declared as at that date, FtC applies; arose later, ordinary regime.
The section 36A FA 2019 12-year discovery window
Section 36A of TMA 1970, inserted by section 80 of the Finance Act 2019, gives HMRC up to 12 years from the end of the tax year to assess offshore income tax or capital gains tax. The section operates independently of behaviour: it applies to careless, deliberate and innocent-error offshore matters equally. For deliberate offshore matters, the longer 20-year window under section 36(1A) takes precedence. For careless, the 6-year section 36(1) was historically the limit, but in offshore cases the 12-year section 36A typically applies as the longer bracket. For innocent error, section 36A is the operative window.
The full four-bracket framework is covered in our discovery assessment time limits page. For WDF purposes, the practical effect is that the disclosure typically spans up to 12 years for innocent-error offshore matters and longer for behaviour-driven cases.
Territory categorisation under Schedule 24 paragraph 4A
Schedule 24 paragraph 4A read with TMA 1970 section 36A defines three territory categories for the purposes of penalty uplift on offshore matters:
- Category 1: territories with full information exchange with the UK. Most EU member states (via CRS plus DAC arrangements), the US (via FATCA reciprocity), Canada, Australia, New Zealand, Japan, and most major economies. Penalty maxima: 30 per cent / 70 per cent / 100 per cent (careless / deliberate-not-concealed / deliberate-and-concealed).
- Category 2: partial information exchange territories. Penalty maxima: 45 per cent / 105 per cent / 150 per cent.
- Category 3: no effective information exchange. Penalty maxima: 60 per cent / 140 per cent / 200 per cent.
For UK landlords with overseas rental property in EU countries (Spain, France, Italy, Portugal, Germany, Ireland) and other major economies, the position is almost always Category 1, and the standard 30 / 70 / 100 maxima apply. Category 2 and 3 cases are typically structured-offshore positions involving specific jurisdictions chosen for their information-exchange status.
The Schedule 21 FA 2015 asset-move penalty
Schedule 21 of the Finance Act 2015 imposes a 50 per cent uplift on the underlying Sch 24 or Sch 41 penalty where assets have been moved from a specified (Cat 2 or 3) territory to a non-specified territory with the main purpose of preventing or delaying HMRC discovery. The asset-move uplift stacks on top of the Sch 24 / Sch 41 offshore Cat 2 / 3 uplifts; it does not replace them. Effective from 26 March 2015.
For most landlord WDF disclosures, Schedule 21 is not in play (the underlying offshore matter is held in a Category 1 territory throughout). Where the offshore structure has involved deliberate inter-territory asset movements aimed at HMRC concealment, Schedule 21 stacks and the combined exposure rises materially.
CRS and the offshore data environment
The structural reason HMRC is identifying historic offshore positions at unprecedented rates is the Common Reporting Standard (CRS). The CRS is an OECD-led automatic information-exchange framework under which financial institutions in participating jurisdictions report account-holder financial information to their domestic tax authorities, who in turn exchange the data with other participating jurisdictions on an annual basis.
The UK joined CRS in 2017, with the first automatic exchanges in 2018. By 2026, the CRS data flow covers over 110 jurisdictions, including all EU member states, most major economies, and many offshore financial centres that previously offered limited information transparency. UK-resident taxpayers with overseas financial accounts, foreign-held property income, or other offshore assets are now substantially more visible to HMRC than they were pre-2017.
The CRS data feed, combined with the DAC7 platform-reporting framework (in force from 1 January 2024), means that HMRC's pre-enquiry discovery of offshore positions has moved from a slow administrative process to an algorithmic risk-scoring system. Landlords with historic undeclared offshore positions should treat early voluntary disclosure as a working-default response rather than as an optional step.
The Schedule 24 paragraph 4A territory categorisation in practice
For practical landlord cases, the territory categorisation under the Penalties for Errors and Failure to Notify (Categorisation of Territories) Order 2011 (as amended) determines whether the offshore uplift is 1x (Cat 1), 1.5x (Cat 2) or 2x (Cat 3). The current list of Cat 2 and Cat 3 territories is published by HMRC and changes periodically. Sessions and landlord-clients should verify the current categorisation at the point of disclosure.
For most landlord WDF disclosures involving rental property in EU member states or other major economies, the territory is Category 1 and the standard 30 / 70 / 100 maxima apply. Cat 2 and Cat 3 categorisations are typically triggered by jurisdictions with no comprehensive double-tax treaty with the UK, no CRS participation, or only partial information-sharing arrangements.
Critically: Spain, France, Italy, Portugal, Germany, Ireland, Netherlands, Belgium, Greece, Cyprus and Malta are all Category 1 for paragraph 4A purposes. UK-resident landlords with rental property in any of these jurisdictions are NOT within the Category 2 or 3 uplifts. The standard 30 / 70 / 100 maxima apply. Commentary suggesting "EU property attracts the offshore uplift" is wrong.

The WDF three-step process
Step 1: Notify
The landlord submits the gov.uk WDF notification via the disclosure service. HMRC acknowledges and issues a Disclosure Reference Number, typically within 14 days. Notification carries no penalty consequence.
Step 2: Disclose
Within 90 days of HMRC acknowledgment (extendable to 180 days for complex cases by request), the landlord submits the full disclosure: year-by-year tax computation, interest from due dates to disclosure date, penalty calculation within the applicable framework (Sch 24 or Sch 41, with paragraph 4A territory uplifts, with FtC overlay where applicable, with Sch 21 stacking where applicable).
Step 3: Pay
Full liability on disclosure, or HMRC time-to-pay arrangement requested. Time-to-pay is more commonly granted for WDF cases than for LPC cases because the absolute sums in dispute are typically larger.
Worked scenario 1: Spanish holiday let, 11 years, post-FtC, unprompted
Background. A higher-rate landlord owns a Spanish holiday let bought in 2013 (2013/14 tax year), let consistently since. Gross income approximately €18,000 per year, sterling-equivalent £15,000. UK net rental profit after allowable expenses approximately £10,000 per year. Spanish income tax paid annually (eligible for foreign tax credit). UK self-assessment never declared the income on the basis "Spanish tax authority deals with Spanish income" (genuine misunderstanding).
Realisation. April 2026. The landlord engages an accountant for unrelated planning. The accountant identifies the WDF route.
Framework analysis. Spain is Category 1 (CRS + comprehensive DTA). Section 36A 12-year offshore window applies: years 2014/15 through 2025/26 are within reach (2013/14 was 12 years ago by 2025/26 year-end). Behaviour: non-deliberate (genuine misunderstanding). FtC applies to 2014/15 through 2017/18 (pre-30-September-2018 non-compliance); post-2018 years (2018/19 onwards) operate under ordinary Sch 41.
Calculation. Total tax loss: £10,000 × 40% × 11 years = £44,000 (gross, before foreign tax credit). After Spanish-paid tax credit (estimated £15,000), net UK tax loss approximately £29,000.
Penalty by year band:
- Years 2014/15 through 2017/18 (pre-FtC, FtC applies): 100 per cent unprompted-full-disclosure floor on the £10,500 of tax loss for these years = £10,500.
- Years 2018/19 through 2024/25 (post-FtC, ordinary Sch 41): non-deliberate unprompted within 12 months of section 7 only on the 2024/25 year (£18,500 of remaining tax across these 7 years). Earlier years outside the 12-month window, 10 per cent floor: approximately £1,500 of penalty across 6 of the 7 years (£15,500 at 10 per cent = £1,550). 2024/25 within 12 months, 0 per cent floor: £0 penalty.
Total penalty approximately £12,000. Interest approximately £4,500.
Outcome. Total settlement: £29,000 net tax + £4,500 interest + £12,000 penalty = £45,500.
Worked scenario 2: deliberate Category 3 offshore concealment, 10 years
Background. A higher-rate landlord holds rental property in a Category 3 jurisdiction (no effective information exchange with the UK) through an opaque corporate structure. The income has been deliberately omitted from UK returns for 10 years. The landlord has used false invoices to extract approximately £200,000 of funds from the structure.
Route choice. CoP9 / CDF is the right route, not WDF. The deliberate-fraud pattern with active concealment puts the case in CoP9 territory. WDF does not provide criminal-prosecution immunity; CoP9 does.
This scenario is included to illustrate the route-choice boundary. Where the deliberate-and-concealed pattern exists, WDF is procedurally available but practically wrong because of the criminal-prosecution risk. The combined Sch 24 + Sch 21 exposure on a 10-year Cat 3 deliberate-concealed case can reach 250 per cent of tax (200 per cent Sch 24 Cat 3 + 50 per cent Sch 21 asset-move uplift on the underlying Sch 24 penalty), with no criminal immunity. CoP9 / CDF caps the criminal risk at the cost of slightly different (and typically slightly lower) penalty mechanics.
Time-to-pay arrangements for substantial WDF settlements
WDF settlements often run materially larger than LPC settlements because of the FtC overlay and the longer 12-year window. Five-figure penalties on five-figure tax exposures are routine; six-figure penalties on six-figure tax exposures occur on substantial offshore positions. HMRC's time-to-pay arrangements are correspondingly more important.
The arrangements are requested as part of the disclosure submission. HMRC reviews the landlord's financial position (income, assets, liquidity) and agrees a payment schedule. Typical arrangements run 12 to 24 months for ordinary cases and up to 60 months for larger cases. Interest accrues on the outstanding balance at HMRC's published rate. The arrangement does not displace the disclosure or alter the penalty position; it simply spreads the payment.
For landlords with limited liquidity, the time-to-pay arrangement is the difference between voluntary disclosure being financially viable and being practically blocked. Property Tax Partners has worked with landlord clients on WDF settlements where the agreed time-to-pay schedule extended over 4 years; HMRC is generally receptive to credible payment proposals where the disclosure itself is robust.
Voluntary disclosure timing and prosecution discretion
Unlike the CoP9 / Contractual Disclosure Facility, WDF does not provide criminal-prosecution immunity. HMRC retains its full prosecution discretion throughout. In practice, prosecution following a voluntary WDF disclosure is rare; HMRC's published policy is to deal with voluntary disclosures civilly where the underlying behaviour is not at the deliberate-fraud-with-concealment end of the spectrum.
The boundary cases are: (i) deliberate-and-concealed conduct where the disclosure is materially incomplete or inaccurate; (ii) substantial sums of tax loss with active concealment evidence; (iii) cases involving multiple connected taxpayers or facilitators. Where these features are present, the right route is CoP9 / CDF (taxpayer-initiated) rather than WDF, because the criminal-immunity component is genuinely material.
For ordinary offshore landlord cases (innocent error, careless, or deliberate-not-concealed positions on Category 1 territories), WDF is the right route and the prosecution risk is in practice low. The disclosure is treated as a civil tax matter, the penalty is negotiated within the Sch 24 / Sch 41 framework with the FtC overlay, and the case closes without criminal-investigation engagement.
How WDF sits alongside the broader disclosure architecture
WDF is one of four HMRC voluntary-disclosure routes:
- Let Property Campaign: UK residential rental. See our LPC page.
- Worldwide Disclosure Facility: offshore income, gains, assets. This page.
- Digital Disclosure Service: UK non-rental matters.
- CoP9 / CDF: deliberate fraud with criminal-immunity protection. See our CoP9 page.
The penalty framework under Schedule 24 FA 2007 and Schedule 41 FA 2008 sits underneath all four routes. WDF adds the offshore territory uplift, the Sch 21 asset-move stacking where applicable, and the FtC overlay for pre-2018 matters. The section 36A 12-year discovery window defines the years in scope for innocent-error offshore disclosures.
One final practical point on WDF positioning. The route is genuinely a voluntary one. HMRC does not require landlords with offshore positions to use WDF; the alternative is to wait for HMRC enquiry. The voluntary-disclosure framing is the structural reason WDF delivers better penalty outcomes than HMRC-opened enquiry: the disclosure-mitigation floors are accessible, the time-to-pay arrangements are typically more generous, and the substantive engagement is on a co-operative rather than adversarial basis. Where the offshore position is genuinely undeclared and the landlord has the means to disclose, the WDF route should be the default rather than a fallback.
If you are a UK landlord with offshore rental property, foreign holiday lets, or any other offshore tax position that has not been correctly declared, the WDF is almost certainly the right route. The form at the foot of the page is the route to a structured first-pass assessment of the years involved, the territory categorisation, the FtC overlay scope, and the appropriate penalty-band positioning.
