Self-employed and something on your credit file.

Why the combination is harder than either on its own

Lenders who are comfortable with self-employed income often want a spotless credit file in exchange, because they are already taking a view on the income. Lenders who are relaxed about adverse credit sometimes want straightforward employed payslips, for the same reason in reverse. Neither is being awkward — each is balancing one uncertainty against another.

The group that will look at both exists and is smaller, and finding it is most of the work. It is also why the order of approach matters even more here than usual: a decline from a lender that was never going to accept both is an expensive way to learn nothing.

How your income will be read

If you are a sole trader, lenders generally work from your SA302 tax calculations and tax year overviews, usually two years, sometimes three, occasionally one. If you run a limited company, most work from salary plus dividends — though some will consider retained profit, which can change the borrowing figure substantially for a director who leaves money in the business.

Whether they average the years or use the most recent one is the detail that matters most when your figures are rising. Same accounts, different lender, materially different answer.

What helps, specifically

• Up-to-date figures. Filed accounts or tax calculations for the most recent year, not last year's because this year's are with the accountant.
• An accountant who answers the phone. Lenders frequently ask for a reference or a projection, and a fortnight's delay there can lose a rate.
• Clean business banking. Underwriters read business statements as well as personal, and a regularly exceeded overdraft speaks louder than a good profit figure.
• An explanation for the adverse. Where it relates to a period the business struggled, that context genuinely helps with a lender that reads rather than scores — say, a bad year during a downturn that has since recovered.

What not to do

Do not let legitimate tax planning — pension contributions, capital spending, expenses — shrink your taxable profit in the year before you apply and then hope the lender does not notice. It is common and entirely legal, and it makes a mortgage application considerably harder, and it is one of the few things that cannot be fixed afterwards. If buying is on the horizon, mention it to your accountant before the year end, not after.
