Quick estimate: borrowing from your SA302 income
Indicative only, not a mortgage offer or advice. Many lenders average your last two years of SA302 income. Some use the latest year, and a few the lower of the two, especially if income is falling. The multiple itself depends on the whole application.
In detail
Without payslips, self-employed income is proved through HMRC and your accounts.
The core documents are your SA302, HMRC's tax calculation from your Self Assessment, and the matching tax year overview, which shows the tax was actually filed and paid. Lenders usually want the last two years and want the figures to reconcile across your accounts, SA302s and bank statements. They typically average the two years of income and apply a multiple of around 4.5.
If your income is rising, some lenders use the most recent year; if it is falling, a cautious lender may use the lower year. A minority accept one year of accounts. Our SA302 mortgage guide explains how to get the documents, and the director mortgage guide covers how company income is read.
