For disposals occurring in the tax year 2023/24, by what date must the claim for reinvestment relief be made?

To determine the correct date for making a claim for reinvestment relief for disposals occurring in the tax year 2023/24, it is essential to understand the timeline related to tax claims in the UK.

Reinvestment relief is a relief available under the Capital Gains Tax framework that allows taxpayers to defer capital gains tax when they reinvest the proceeds from the disposal of an asset into a qualifying replacement asset. For disposals made in the tax year 2023/24, the statutory deadline for submitting claims aligns with the requirement to submit self-assessment tax returns for that year.

In general, tax returns for a given year must be submitted by January 31 of the year following the end of the tax year. Thus, for the tax year 2023/24, which ends on April 5, 2024, the deadline for submitting the related self-assessment tax return is January 31, 2025. However, if a taxpayer wishes to claim relief at that time, they have an extended period to make claims relating to reinvestment relief—typically up to four years from the end of the tax year in which the disposal occurred.

This means that claims can be made until January 31, 2029,
