How do lenders assess income for sole traders?

Most lenders use your net profit as declared on your Self Assessment tax return (SA302). They typically take an average of the last 2–3 years. If your income has grown year-on-year, some lenders will use just the most recent year's figure. We know which lenders take the most favourable approach for your specific income pattern.

What documents do I need as a sole trader?

You'll typically need: 2–3 years SA302 tax calculations and corresponding HMRC Tax Year Overviews, your last 3 months' personal bank statements, last 3 months' business bank statements, and proof of address/identity. Some lenders also ask for accountant-prepared accounts, but many will accept SA302s alone.

My income varies year to year — is this a problem?

It depends on the pattern. If income is growing consistently, lenders view this positively. If it has fallen recently, some lenders will use the lower figure, others the 2-year average. A significant one-off drop can raise questions that we'll help you explain clearly. We know which lenders take the most flexible view on fluctuating income.

Can I include my gross income rather than net profit?

No — lenders base their assessment on net profit, not turnover. If you have high business expenses (which reduce your net profit), this will affect your maximum borrowing. In some cases it's worth reviewing your expense claims with your accountant before applying, though this is ultimately a tax decision.

How long do I need to have been a sole trader?

Most mainstream lenders require 2–3 years of trading history. However, some specialist lenders will consider applications with 1 year of accounts, particularly if you have a strong income, a stable employment history in the same industry, or an accountant's projection. See our dedicated guide for 1-year self-employed mortgages.

Income Assessment

How Lenders Assess Sole Trader Income

As a sole trader, your borrowing capacity is based on your net profit — what's left after business expenses, as declared in your Self Assessment tax return. Lenders don't use your turnover or gross income.

Most lenders take an average of the last 2–3 years' net profit and apply their income multiple (typically 4–4.5×) to calculate maximum borrowing. However, the approach varies significantly between lenders — and choosing the right one can make a material difference to how much you can borrow.

Growing income? Some lenders use the most recent year only

Consistent income? 2-year average typically works well

Declining income? We'll find lenders that look at the full picture
