The primary incentive is financial. HMRC’s penalty framework distinguishes between unprompted disclosures (where you come forward before HMRC contacts you) and prompted disclosures (where HMRC finds the problem first). For careless errors, unprompted disclosure can result in penalties as low as zero per cent of the additional tax. For deliberate errors, unprompted penalties start at 20 per cent compared with 35 per cent for prompted. On a significant underpayment, the difference between prompted and unprompted can be tens of thousands of pounds.
Beyond the financial saving, there is the predictability. When you disclose voluntarily, you control the process. You know what is being disclosed, when, and on what terms. When HMRC discovers the problem, you are reacting to their timeline, their information requests, and their assessment of the severity. Most clients who come to us for voluntary disclosure also report that the relief of resolving a long-standing problem is as valuable as the penalty reduction.
The most common disclosure scenarios we handle involve undeclared UK rental income from properties that were let without the income being included on a tax return, missed 60-day CGT returns on property disposals where the reporting obligation was not identified, overseas property income that was not declared under UK tax rules, historical errors that have accumulated over multiple tax years where the client knew something was wrong but did not know how to correct it, and income from Airbnb or short-term lets that was not declared because the client was unsure whether it needed to be. These situations are common. They are correctable. HMRC has specific disclosure facilities designed to handle them.
HMRC operates a dedicated disclosure facility for landlords with undeclared rental income called the Let Property Campaign. It offers a structured process and defined penalty terms for property-related disclosures. If your non-compliance relates to rental income, this is usually the most appropriate route. We prepare and submit Let Property Campaign disclosures regularly and can manage the entire process from initial assessment through to HMRC acceptance and payment.
We have a confidential initial conversation to understand your situation. This is without obligation. Nothing is disclosed to HMRC at this stage.
We review your affairs and identify every area of non-compliance. This must be thorough because a partial disclosure is worse than no disclosure -- if HMRC subsequently discovers additional issues you did not include, the entire disclosure is treated as prompted and the penalties increase.
We calculate the additional tax, interest, and estimated penalties for each year and each tax affected.
We prepare and submit the disclosure through the appropriate HMRC facility -- the Let Property Campaign, the Digital Disclosure Service, or a direct disclosure depending on the circumstances.
HMRC reviews the disclosure, accepts or queries it, and confirms the final settlement. We agree a payment schedule if the amount cannot be paid in full immediately.
