Get your Overlap Relief figure
When and how to include Overlap Relief in your 2023 to 2024 tax return if you have transition profit.
Before including Overlap Relief in your Self Assessment tax return, you should check to see if you are affected by Basis Period Reform.
You can use Overlap Relief in the 2023 to 2024 tax year if your accounting end date:
- does not align with the tax year (accounting dates between 31 March and 5 April align with the tax year)
- has been changed to align to the tax year, but you did not use any Overlap Relief due
- was changed during the 2023 to 2024 tax year, but does now align with the tax year
If you have stopped trading in the 2023 to 2024 tax year you can still include Overlap Relief in your return for that year.
Section 19 of how to calculate your taxable profits (Self Assessment helpsheet HS222) explains how to include Overlap Relief in your tax return.
How to work out your Overlap Relief figure
Your Overlap Relief figure may already be entered as Overlap Profit Carried Forward on a previous Self Assessment return form if it included :
- trading income on Self Employment (SA103)
- trading income on Partnership (SA104)
- both trading income on Self Employment and Partnership
If you do not know your Overlap Relief figure, and you cannot find it on your previous Self Assessment returns, HMRC may be able to help.
This service can only provide an Overlap Relief figure if this information has been provided in a previous tax return. If this information has not been provided the service may be able to provide historic profit figures to allow Overlap Relief to be recalculated.
Do not use this service if you are working as a trust, estate, or non-resident company that has trading income, contact HMRC to find out how to get your overlap relief figure.
