Use this service to make a disclosure if you, your company or client haven't declared all income or gains.
Use the online form service if you’re:
- an individual

- an agent
You, your company or client will also need to:
- be eligible for a HM Revenue and Customs (HMRC) Campaign
- want to disclose income or gains that wholly or partly relate to an offshore issue as part of the Worldwide Disclosure Facility
You can also use the online form service if you don’t qualify for a current HMRC campaign, but haven’t declared the right amount of income or tax for one or more of the following:
- Income Tax
- Capital Gains Tax
- National Insurance contributions
- Corporation Tax
You’ll need to sign in to, or set up a Government Gateway account to use the service.
