If you're self-employed, lenders may require an SA302 and tax year overview as proof of earnings for mortgages or loans. These documents verify income declared on your self-assessment tax return and are easily accessible via HMRC. Learn how to obtain them.

The use of these forms has become more widespread since mortgage regulations began requiring self-employed individuals to provide verifiable evidence of income. The SA302 serves as proof of income for the last four years of self-assessment tax returns.

The SA302 document provides a detailed breakdown of the income reported on the taxpayer’s self-assessment tax return, including commercial versions of the tax return. Meanwhile, the tax year overview confirms the tax due based on the return submitted to HMRC, showing any payments made, and cross-referencing the Tax Calculation with HMRC’s records.

Self-assessment taxpayers can request an SA302 tax calculation through HMRC’s online service. After submitting an online tax return, it typically takes around 72 hours for the documents to become available for printing.

Most lenders will accept an SA302 printed directly from online accounts or from the commercial software used to submit tax returns. HMRC has been actively working with the Council of Mortgage Lenders and its members to expand the number of lenders willing to accept self-serve copies of these documents as valid proof of income.
