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.
