Paying tax outside self assessment

Simple assessment and real-time reporting for capital gains tax (CGT) are two ways for HMRC and taxpayers to sidestep self assessment for income and gains.

HMRC sent out a record number of simple assessments for 2023/24. We explain what they are and explore some of the problem areas. We also explain how the often overlooked real-time reporting for CGT works and look at current issues with CGT reporting more generally.
