The Annual Tax Summary is a document provided by HMRC that shows details of the tax you pay and how this is used by government.

The Annual Tax Summary shows:

• your taxable income from all sources that HMRC knew about at the time that it was prepared;
• the rates used to calculate your Income Tax and National Insurance contributions; and
• a breakdown of how the UK government spends your taxes – this makes government spending more transparent.

HMRC makes it clear that the tax summaries are for information purposes only and neither taxpayers nor agents should take any action based on the contents of the summary. The summaries are available online via the Government Gateway.

Taxpayers cannot access an Annual Tax Summary if they have paid no income tax or if information is outstanding. The Annual Tax Summary might also be different from other HMRC tax calculations because a taxpayer's circumstances have changed, or sources of income were not included.
