Do I need to do a digital disclosure?
Posted on 04 Aug 2025, by Jeremy Johnson

A digital disclosure is an online submission to notify HM Revenue & Customs (HMRC) about past under‑payments or errors in your tax affairs.
HMRC’s Digital Disclosure Service (DDS) is designed for individuals and businesses to bring their tax affairs up to date in a transparent way (read more about the DDS here).
If you’re asking, “do I need to do a digital disclosure?”, here are the scenarios to consider:
When a digital disclosure is suitable
A digital disclosure can be made when:
- You’ve discovered an unpaid tax liability from previous years.
- You’ve deliberately or unintentionally under‑declared income or gains.
- HMRC has sent you a nudge letter, suggesting you review your tax affairs.
The DDS can be used to disclosure undeclared income from self-employment, dividends, Capital Gains Tax and Corporation Tax.
HMRC has several specific disclosure facilities, notably:
- Let Property Campaign (LPC) – for undisclosed rental income
- Worldwide Disclosure Facility (WDF) – for undeclared offshore income, assets or gains
- Contractual Disclosure Facility or Code of Practice 9 (COP9) – for deliberate behaviour and tax fraud
If you need help, inTAX’s experts can guide you to the right disclosure route.
What is a voluntary disclosure?
Making a disclosure of your unpaid tax liabilities to HMRC before they write to you or before HMRC starts a tax investigation is called a ‘voluntary disclosure’.
It’s a proactive move and that will result in reduced penalties. You can make a voluntary disclosure via DDS, WDF or COP9 – your choice depends on the nature of the tax issue.
Advantages of digital disclosure
- Brings your tax affairs up to date, giving you peace of mind
- Lower penalties for voluntary disclosures
- Structured process with 90 day reporting window
- Often no or minimal questions asked by HMRC
- Specialists, like inTAX, can handle disclosures end to end, minimising stress

So, do I need to make a digital disclosure?
If your affairs involve complex matters – especially offshore income – or deliberate tax evasion, a different route like the Worldwide Disclosure Facility or Contractual Disclosure Facility might be more suitable. You should absolutely discuss your circumstances with a specialist!
However, if any of the following apply, a digital disclosure might be right for you:
- You’ve underpaid tax and want to get up to date
- You want to voluntarily disclose before HMRC contacts you
- You’ve received a letter from HMRC about your tax position
Before contacting HMRC, you should always reflect on your tax situation, errors, omissions or recent contact from HMRC.
