HMRC has published guidance on filing Self Assessment tax returns using the SA100 form for the tax year running from 6 April 2025 to 5 April 2026. The guidance covers how to report income, claim available tax reliefs, and request any tax repayment you may be entitled to. Self-employed individuals and others with income not covered by PAYE must use this process to meet their tax obligations.
