Updated: The Settlement Opportunities helpline telephone number has been updated.

HM Revenue and Customs (HMRC) is inviting some participants in certain schemes to settle their tax liabilities by agreement, without the need for legal action. This settlement opportunity offers both the taxpayers and HMRC the best opportunity to resolve these disputes in a way which is cost-effective and consistent. Where people decline the settlement opportunity, HMRC will increase the pace of their investigations and move disputes quickly to legal action.
