How Does HMRC Voluntary Disclosure Work in the UK and Can It Reduce Penalties?
Approaching HMRC proactively using the voluntary disclosure route can be the difference between a manageable resolution and facing severe penalties or prosecution. Whether your issue involves self-assessment errors, unreported rental income, or oversights under schemes such as the Let Property Campaign, disclosing before HMRC makes an enquiry protects you from harsher sanctions.
The HMRC voluntary disclosure process allows individuals and businesses to come clean about tax irregularities, rectifying mistakes and reducing financial and legal risks. By making a full, timely, and honest disclosure, you can secure much lower penalties, avoid escalation, and move forward with confidence.

What Is HMRC Voluntary Disclosure in the UK and How Does It Work?
The HMRC Voluntary Disclosure Service (VDS) is a formal route for individuals or businesses to declare past tax errors or income that hasn’t previously been reported. This process is designed to encourage honesty, correcting oversights—whether innocent or deliberate—while reducing both penalties and the risk of a criminal investigation.
You can use HMRC voluntary disclosure whether you’re an employee who overlooked freelance earnings, a landlord who failed to report rental receipts, a director with an overdrawn director’s loan, or anyone with unreported VAT, offshore income, or cryptocurrency gains.
The process typically involves:
- Notifying HMRC of your intention to disclose, commonly via the Digital Disclosure Service.
- Providing a detailed breakdown of the errors and periods affected.
- Calculating and paying any tax liability, interest, and a potentially reduced penalty.
- Cooperating with HMRC queries until the matter is formally closed.
If you have questions about undeclared tax, our tax dispute solicitors can advise you with complete confidentiality.
Which Tax Errors and Undeclared Income Can Be Disclosed to HMRC?
Any tax error or irregularity, regardless of size or complexity, can be disclosed on a voluntary basis to HMRC. This includes:
- Omissions from freelance/consultancy or side jobs declared through self-assessment.
- Rental income not disclosed under the HMRC Let Property Campaign.
- Understated sales or misfiled returns for VAT or Corporation Tax.
- Undeclared profits from the sale of assets, such as stocks, property, or crypto assets (affecting Capital Gains Tax).
- Overdrawn or undeclared director’s loan accounts.
- Offshore bank interest or foreign property income.
A tax “error” covers both innocent mistakes as well as non-disclosure. HMRC welcomes honest disclosures of both understatements and misstatements.
What Counts as a Tax Irregularity Under UK Law?
Under Finance Act 2008, Schedule 24, a tax irregularity includes inaccuracies, omissions, failures to notify, or misstatements about your or your company’s tax liability. This applies whether the issue is a simple oversight or more complex non-disclosure.
If you are unsure whether your error qualifies, ask our specialist solicitors to review your circumstances and confirm your disclosure options.
Can I Use the Voluntary Disclosure Service for Historic Income and Past Years?
Yes, voluntary disclosure allows reporting of historic errors going back several years. The required period depends on the type of misstatement:
- 4 years for genuine mistakes
- 6 years for carelessness
- Up to 20 years for deliberate acts
What Are the Benefits of Making a Voluntary Disclosure to HMRC?
Making a voluntary disclosure offers several compelling benefits:
- Substantially reduced penalties compared to being “discovered” by HMRC.
- Lower risk of criminal investigation or prosecution.
- More control over the process—including negotiation, evidence, and timing.
- Resolution without workplace disruption, press attention, or damaging business audits.
- Opportunity to demonstrate honesty and mitigation.
If you are considering voluntary disclosure, reaching out to our experienced solicitors early maximises your chance of a smooth and discreet resolution.
Will Voluntary Disclosure Reduce My Penalties or Prevent Prosecution?
By coming forward before HMRC contacts you, you can almost always benefit from a reduced penalty—often by half or more. Criminal prosecution is extremely rare for voluntary, full, and honest disclosures unless the case involves large-scale or highly organised fraud.
How to Disclose Tax Errors Through HMRC Voluntary Disclosure
A structured, careful approach is crucial for a successful disclosure. The process involves:
- Notify HMRC: Request to disclose via the Digital Disclosure Service; you’ll receive a unique reference number within days.
- Collate Evidence: Gather all financial records and supporting documents covering each year or transaction affected.
- Calculate Liability: Work out your true tax liability, interest, and penalty—precision here maximises credibility.
- Prepare a Narrative: Clearly explain what went wrong and why, outlining all relevant details and periods.
- Submit Disclosure: Provide your calculations, evidence, and supporting documents via HMRC’s online portal.
- Offer and Pay: Propose to settle the full amount owing. If unable to pay in full, discuss an affordable payment plan.
- HMRC Review: Respond promptly to any HMRC questions or requests for further evidence.
- Case Closure: Once HMRC is satisfied, they will issue a formal settlement to confirm the matter is resolved.
To ensure nothing is missed in your submission, consider a review by our expert lawyers who can check your evidence and calculations before you approach HMRC.
What Documents and Evidence Do I Need to Prepare for HMRC?
To support your disclosure, gather:
- Bank statements for each affected year
- Detailed business accounts (if self-employed or a company director)
- Tenancy agreements, rental ledgers, and letting agent statements (for landlords)
- Payslips, dividend vouchers, or share sale receipts
- Proof of overseas income (like foreign bank or investment statements)
- Copies of submitted tax returns showing errors or omissions
What Penalties Can HMRC Apply and How Are They Reduced by Voluntary Disclosure?
HMRC’s penalty regime is set by Finance Act 2008, Schedule 24:
- Careless errors: Up to 30% of the underpaid tax.
- Deliberate but not concealed: 20% to 70%.
- Deliberate and concealed: 30% to 100%.
Disclosures made voluntarily and before HMRC contacts you are treated much more leniently:
| Behaviour | Standard Penalty | Unprompted Voluntary Disclosure |
|---|---|---|
| Careless | 0–30% | 0–15% |
| Deliberate, Not Concealed | 20–70% | 20–35% |
| Deliberate and Concealed | 30–100% | 30–50% |
Our tax lawyers can advise you precisely how to present your case to achieve the lowest possible penalty.
How Does HMRC Distinguish Between Careless Mistakes and Deliberate Evasion?
- Careless error: Accidentally omitting income or misunderstanding a rule—e.g. missing £2,500 in interest income due to poor records.
- Deliberate but not concealed: Knowingly underreporting, but not actively hiding—e.g. not declaring consulting fees of £10,000.
- Deliberate and concealed: Fabricating paperwork or hiding accounts—e.g. falsifying invoices to shift £30,000 in overseas proceeds.
What Happens After You Make a Voluntary Disclosure to HMRC?
Once your disclosure has been submitted, HMRC will review the documents:
- They typically acknowledge disclosure within a week.
- HMRC will check your figures against their data sources and may request clarification.
- If your offer matches HMRC’s findings and documentation is complete, they accept and issue a settlement.
- If more is owed or information is missing, HMRC can adjust your obligation and increase penalties.
Having expert representation can ensure a smooth process, limit HMRC queries, and help close your case efficiently.
What Is the Typical Timeline for a Disclosure, and What Should You Expect Next?
Most VDS disclosures are completed within 4–8 weeks. Complex cases (especially those involving multiple tax years or offshore transactions) may take longer. Delays in responding to HMRC requests slow down settlement and increase the risk of additional penalties or interest charges.
What Laws and Deadlines Apply to HMRC Voluntary Disclosure in the UK?
The main legislation includes:
- Finance Act 2008 (Schedules 24 & 41): Covers tax penalties for inaccuracies and failures to notify HMRC.
- Finance Act 2020: Addresses enforcement in cross-border and offshore cases.
- Income Tax (Earnings and Pensions) Act 2003: Governs PAYE and self-employment tax errors.
- HMRC Compliance Handbook: Sets out day-to-day HMRC procedures and deadlines.
Time limits depend on the level of intent:
- Innocent errors: Disclosures must generally cover the previous 4 years.
- Careless errors: Up to 6 years.
- Deliberate understatements: Up to 20 years.
What Do the Courts Say About HMRC Voluntary Disclosures and Penalties?
| Case | Facts | Outcome | Why It Matters |
|---|---|---|---|
| Seymour v HMRC [2012] UKFTT 287 (TC) | Omitted rental income declared before HMRC enquiry | Reduced penalty due to prompt disclosure | Courts reward early, full voluntary disclosure |
| Darby v HMRC [2016] UKFTT 455 (TC) | Accountant disclosed errors before formal HMRC investigation | No criminal penalty, lighter financial sanction | Early admission usually avoids prosecution |
| Nash v HMRC [2021] UKUT 16 (TCC) | Delayed disclosure after HMRC enquiry notice | Higher penalty, less mitigation | Waiting for HMRC to act leads to much harsher treatment and higher cost |
Risks of Ignoring Tax Errors: What Happens If You Do Not Disclose to HMRC?
Choosing not to disclose tax errors increases your risk of:
- A full-scale HMRC audit or criminal investigation.
- Penalties of up to 100% or more of the unpaid tax plus daily interest.
- Potential criminal prosecution in serious or repeated cases.
- Being named on HMRC’s public “deliberate tax defaulters” list, damaging personal and business reputation.

Frequently Asked Questions
Can I be prosecuted for tax evasion if I use the HMRC Voluntary Disclosure Service?
Prosecution is extremely unlikely where the disclosure is full, honest, and unprompted, except in grave cases involving fraud or substantial sums.
What information do I need to include in a voluntary disclosure to HMRC?
Disclose all types of income or errors, list every year and relevant financial figure, explain why the issue arose, and provide solid evidence. Our guide above explains each step.
How far back can HMRC look at my undeclared tax errors?
Depending on intent: 4 years for innocent errors, 6 years for carelessness, and up to 20 years for deliberate wrongdoing.
What if HMRC has already started an enquiry into my tax affairs?
You cannot use the VDS for the tax issue under formal investigation, but you should seek urgent advice from our lawyers on how to limit your liability.
Are company directors personally liable for errors disclosed voluntarily?
Ordinary mistakes are usually company liabilities, but directors are personally exposed if HMRC persuades a tribunal there was dishonesty or fraud.
Can I disclose income from overseas property or investments?
Yes. The VDS covers UK and worldwide income. Offshore errors may attract higher penalties and extra scrutiny.
How is a ‘reasonable excuse’ considered by HMRC in voluntary disclosures?
If you had a valid reason (serious illness, bereavement), HMRC may reduce or waive penalties—provided the error is corrected as soon as reasonable.
Does HMRC always accept my explanation or evidence?
No. They may request further information or dispute your figures if evidence is incomplete. Robust, clearly presented documentation helps prevent disputes.
How quickly can a tax solicitor respond if I’m worried about a tax irregularity?
Our tax lawyers can often give tailored, confidential guidance within 24 hours.
