Worked example

How this date is determined
The UK personal tax year runs from 6 April to 5 April the following year — a historical quirk dating back to the switch from the Julian to the Gregorian calendar. The end date, 5 April, is a fixed statutory date with no weekend adjustment.
Because it is a fixed calendar date, the countdown targets the next 5 April. Many allowances and reliefs (such as the ISA allowance) reset at the tax year boundary, which is why this date matters for end-of-year tax planning.

Frequently asked questions
When does the UK tax year end?
The UK tax year ends on 5 April, and the next tax year begins on 6 April. This applies to income tax, capital gains and personal allowances such as the annual ISA subscription limit.
Why does the UK tax year end on 5 April?
It is a legacy of the 1752 change from the Julian to the Gregorian calendar and later adjustments, which shifted the old New Year (25 March) forward to 5 April. The date has stayed fixed ever since.
Is the tax year end the same as the Self Assessment deadline?
No. The tax year ends on 5 April; the Self Assessment filing and payment deadline for that year is the following 31 January. See the UK Self Assessment deadline countdown for that separate date.
What should I do before the tax year ends?
Common year-end tasks include using your ISA and pension allowances and reviewing capital gains, but the right actions depend on your circumstances. This page is informational only — speak to a qualified adviser.
