How lenders assess self-employed income

  • Sole traders — usually 2 years of SA302s plus tax year overviews; lenders often average net profit.
  • Ltd company directors — most lenders use salary + dividends; some specialists use salary + retained profit.
  • Contractors — day-rate × 5 × 46–48 weeks for specialist contractor lenders.
  • CIS subcontractors — some lenders use gross CIS day-rate; others fall back to net profit on the SA302.

Document checklist

  • SA302 or tax calculation (latest 2 years).
  • Tax year overview from HMRC.
  • Certified business accounts (last 2 years).
  • Dividend vouchers if Ltd director.
  • 3 months business + personal bank statements.
  • ID and proof of address.
  • Proof of deposit.

Frequently asked questions

How many years of accounts do I need? +
Most high-street lenders want 2 years. A growing number accept 1 year if profits are strong and you have a good credit profile. Specialist lenders can go further on this.
Do Ltd directors use salary + dividends or retained profit? +
High-street lenders typically use salary + dividends. Some specialist lenders use salary + share of retained profit, which often boosts the borrowing figure.
I’m a contractor on day-rate — how is income calculated? +
Specialist contractor lenders use day-rate × 5 days × 46–48 weeks as gross annualised income, even if your accounts show lower drawings.
What documents will I need? +
SA302s + tax year overviews (sole traders), 2 years of certified accounts (Ltd), 3 months of business + personal bank statements, ID and proof of deposit.

Rate comparison with context

Compare Mortgage Rates is built around comparing mortgage costs beyond the headline rate. Product fees, term, loan-to-value and lender criteria can all change what is appropriate for a borrower.
