What Is the Digital Disclosure Service?
The Digital Disclosure Service (DDS) is HMRC's general-purpose online tool that allows individuals and businesses to voluntarily disclose tax they owe. Unlike the Worldwide Disclosure Facility, which is specifically for offshore matters, the DDS covers a broad range of domestic and international tax issues.
It is designed to be a simple, accessible way for taxpayers to come forward and regularise their tax affairs before HMRC discovers the issue independently.
Who Should Use the DDS?
The DDS is suitable for anyone who:
- Has undeclared income from any source — UK or overseas
- Has not registered for Self Assessment when they should have
- Has made errors on previous tax returns
- Has undeclared capital gains
- Owes tax from previous tax years that has not been paid
- Has been involved in a tax avoidance scheme they wish to exit
How Does the DDS Work?
The process follows a straightforward sequence:
- Step 1 — Notify HMRC: Tell HMRC you want to make a disclosure via the online service. You will need your National Insurance number or UTR
- Step 2 — Reference Number: You receive a disclosure reference number from HMRC
- Step 3 — Prepare Your Disclosure: Calculate the tax owed, including interest and any applicable penalties. HMRC allows 90 days from notification to submit
- Step 4 — Submit & Pay: File your disclosure and make payment
Benefits of Using the DDS
- Reduced penalties: Voluntary, unprompted disclosures generally attract lower penalties
- Avoid criminal investigation: Coming forward proactively significantly reduces the risk of criminal proceedings
- Quick resolution: The online process is efficient and avoids lengthy correspondence
- Peace of mind: Once settled, you can move forward knowing your tax affairs are in order
Penalties and Consequences
The penalty you pay depends on several factors:
- Whether the disclosure is unprompted or prompted by HMRC
- The behaviour involved — careless, deliberate, or deliberate and concealed
- The quality of your disclosure — its completeness, accuracy, and timeliness
In the best cases, penalties can be suspended or reduced to zero. In more serious cases, they can reach 100% of the tax due.
