Tax year end 2025/26
Each tax year, you have allowances you can use to maximise the tax efficiency of your savings. The UK tax year runs from 6 April to 5 April the following year.
The value of your investments and the income from them may go down as well as up, and you could get back less than you invested.
What is tax year end?
In the UK, the tax year is a period of 12 months running from 6 April to 5 April.
Tax year end is a term to describe the end of the tax year, simple. The last day of the current tax year (2025/26) is 5 April 2026. That’s the last day you can use up your annual allowances before they reset on 6 April.
What are the annual allowances for the current tax year?
Most tax allowances and reliefs run from April to April each year and, apart from pensions, often can’t be carried over so if you don’t use them you lose them. Below we have listed some of the key allowances to be aware of.
