SA302 tax calculation or P800
If you file Self Assessment, HMRC’s SA302 tax calculation and tax year overview serve as proof of income. Employees taxed through PAYE may receive a P800 if they paid too much or too little.
How long to keep it: At least 22 months after the end of the tax year, 5 years after the filing deadline if you are self-employed.
The IRS does not send an assessment in normal cases: your filed return is accepted as is. Lenders ask for a tax return transcript, available free from your IRS online account. Notices only arrive if something changes.
How long to keep it: Generally 3 years, longer in some situations (up to 7).
