The paperwork problem
PAYE borrowers have it easy on the documentation side. A couple of payslips, a job letter, and the income question is answered. Self-employed borrowers usually need at least two years of financials and IR3s, plus supporting evidence that the trend is stable or improving.
That's not a barrier — it's just a longer list. Get it organised early and the process gets a lot smoother.
Why self-employed income looks messy
Good self-employed clients often show lower taxable income than a PAYE person on the same real income, because they're claiming legitimate expenses and using company structures that retain earnings. The bank's servicing calculator reads taxable income first, which understates capacity.
The other issue is variability. If one year was much bigger than the other, banks usually take a conservative view — sometimes the lower year, sometimes an average. Presenting the story properly matters.
How lenders actually read it
Lenders differ meaningfully on how they treat self-employed income. Some add back specific expenses (depreciation, one-off costs, interest that will disappear post-purchase). Some accept the higher of the last two years if the trend is up. Some require an accountant's letter certifying current run-rate.
An adviser who works across a panel of lenders knows which lender's approach fits your numbers best. Sending the same file to five banks won't give the same answer — and sending it to the wrong one first can leave a footprint that hurts subsequent applications.
What to prepare
Two years of financial statements (P&L and balance sheet). Two years of IR3s or company tax returns. Current-year interim figures if you're partway through a year. Bank statements for both personal and business accounts, usually the last three months. A clean explanation for any big movements year-on-year.
Talk to your accountant before you apply — sometimes a small adjustment to how the current year is being run improves how the numbers read to a lender.
Lender choice matters more than the rate
For self-employed borrowers, the rate you get is a smaller variable than whether you get approved at all, and at what loan size. A quarter-percent rate difference is trivial next to being able to buy a house that actually fits your family.
