Self Assessment Return Check (UK)
A Self Assessment return is the tax return used to declare taxable income and gains to HMRC under the UK Self Assessment regime, together with the records that support the figures entered.
What is this?
A Self Assessment review usually looks at the return itself, working papers, income records, expense evidence, capital gains schedules, and any claims or elections made in the filing. The key issue is whether the figures, relief claims, and disclosures are supported by records that match the tax year and filing basis used.
Relevant law often includes the Taxes Management Act 1970, the applicable tax legislation for the income or gains involved, HMRC guidance, and the filing deadlines in force for the return.
Key legal requirements
- the taxpayer identity, UTR, tax year, filing basis, and deadlines must be correct
- all figures entered should be supported by records for income, gains, deductions, and reliefs claimed
- the return should treat each source correctly, including employment, property, trading, dividends, and capital gains where relevant
- any amendment, disclosure, or payment position should align with the return chronology and supporting documents
Why this matters
Errors in a return can trigger penalties, interest, HMRC enquiries, or the need for later amendment where the supporting records do not justify the tax position taken.
