Worldwide Disclosure Facility Penalties: How Much Will I Pay and How to Reduce Them

Worried about penalties on undeclared overseas income? You are not alone. Penalties are the biggest fear for most people thinking about the Worldwide Disclosure Facility.

The good news: HMRC’s rules reward people who come forward early and are open. This guide explains how the figures are worked out.

How HMRC works out a penalty

Under the Worldwide Disclosure Facility, you calculate the penalty yourself as part of the disclosure. HMRC then checks it.

Four things decide the percentage:

1. Behaviour: did you take reasonable care, were you careless, or was it deliberate?
2. Prompted or unprompted: did you come forward before HMRC had reason to believe it would find out?
3. Territory category: which country the income came from and how much it shares information with the UK.
4. Quality of disclosure: how fully you tell, help and give HMRC access to records.

Behaviour: the starting point

The same error can lead to very different penalties depending on why it happened.

These are the standard rates for Category 1 territories. Offshore matters in other categories are higher, as explained below.

Most people with forgotten overseas savings or rent fall into the careless category. Getting this classification right is critical.

Offshore uplifts: why the country matters

For offshore income, HMRC sorts countries into categories based on how much tax information they share with the UK.

• Category 1: standard rates apply.
• Category 2: rates are increased by half (1.5 times).
• Category 3: rates are doubled, so the maximum can reach 200%.

That is why the same mistake can cost more if the money was held in a country with limited information exchange.

Other offshore penalties to know about

A few additional penalties can apply in more serious cases:

• Failure to correct: for offshore tax from before April 2017 that was not put right by 30 September 2018. The standard penalty is 200%, which can be reduced to no lower than 100%.
• Asset-based penalty: in some deliberate cases involving more than £25,000 of tax in a year, a penalty of up to 10% of the asset’s value.
• Offshore asset moves penalty: an extra 50% of the original penalty if assets were moved to avoid disclosure.

These do not apply to most everyday cases, but an adviser will check.

Late payment interest

Interest is not a penalty. It is charged because the tax was paid late.

HMRC’s late payment interest is currently set at the Bank of England base rate plus 4%, running from the original due date for each year. You include it in your disclosure.

Practical ways to reduce your penalty

• Act before HMRC contacts you. An unprompted disclosure has a much lower minimum.
• Disclose everything. Partial disclosures lose reductions and can damage trust.
• Explain the circumstances clearly. Show why the error was careless rather than deliberate, with evidence.
• Help HMRC fully. Provide organised records and accurate calculations.
• Meet the 90-day deadline. Late or incomplete submissions undermine the disclosure.

A simple worked example

This is an illustration only. Real figures depend on your facts.

Sarah moved to the UK and kept a savings account in her home country. She did not realise the interest was taxable here. A review shows £4,000 of extra UK tax across several years, after foreign tax credit relief.

• Behaviour: careless, because she did not check the rules.
• Disclosure: unprompted, because she came forward before any HMRC letter.
• Territory: Category 1.

With full help and clear records, the penalty could fall towards the bottom of the 0% to 30% range. At 10%, the penalty would be £400, plus late payment interest on the tax for each year.

If Sarah had waited for HMRC to write first, the minimum would rise to 15%. If the money had been in a Category 3 country, the rates would double.

The lesson is simple: timing and openness have more effect on the final bill than almost anything else.
