5 April 2027: End of the tax year

The 2026/27 tax year ends on 5 April 2027. Allowances that are not used by then are gone.

Who it applies to

Is this you?

Everyone, and especially company directors deciding on dividends and pension contributions, and anyone with ISA or capital gains allowances to use.

What has to happen

The detail

The personal allowance, the dividend allowance, the ISA allowance and the Capital Gains Tax annual exempt amount all run by tax year and do not carry forward. A dividend voted on 6 April falls into the next year's figures.

For a company, the timing of a bonus, a dividend or a pension contribution around 5 April can move tax from one year to another, which is worth a conversation in March rather than a discovery in January.

If you miss it

What it costs

Nothing is filed on this date, so nothing is late. The cost of missing it is an allowance unused.

What to do

Now

Have the salary, dividend and pension conversation in February or March. The salary and dividend calculator gives a first view.
