Self-employed mortgages with one year of accounts

Yes, some lenders will offer a mortgage to self-employed applicants with one full year of accounts or one year of tax calculations. Most lenders still ask for two to three years of figures, according to MoneyHelper, How to apply for a mortgage, accessed 21 Oct 2026, so the choice is narrower and each lender sets its own conditions.

Lenders that accept one year usually want that year to be complete and filed with HMRC, so that a tax calculation and tax year overview exist for it. A partly completed first year is rarely enough on its own, because there is no filed figure to base the income on.

The wider rules on how lenders read self-employed income, documents and affordability are covered in the guide to self-employed mortgages. This page focuses on what changes when the trading history is short.

Continuity is the factor lenders weigh most when a trading history is short. An applicant who worked as an employed electrician for years and then started trading as a self-employed electrician is seen as lower risk than someone who started a business in an unrelated field, even with the same first-year profit.

Lenders may ask for evidence of the previous employment, such as P60s or a reference, alongside the first year's figures. A move from sole trader to limited company in the same trade is often treated as continuous trading, so the sole-trader years count towards the history.

Changes of business structure, partnership splits and moves between sectors are read case by case. A short written explanation of the change, supported by dated documents such as contracts or invoices, helps a manual underwriter understand why the history looks shorter than the experience behind it.

Applicants who have been self-employed for less than a full year, with no filed return yet, have the fewest options. A small number of lenders may consider projections or an accountant's forecast, but most will wait until the first year is filed and a tax calculation is available from HMRC.

HMRC tax calculations can be downloaded once a Self Assessment return has been filed, according to GOV.UK, Get your SA302 tax calculation, accessed 21 Oct 2026. A return filed earlier in the Self Assessment window produces an SA302 sooner than one filed close to the deadline.

Contractors are an exception. Lenders that assess contract rates may consider a first contract where the work matches a previous employed role, as explained on the page about mortgages for contractors.

With one year of figures, lenders generally use that single year's net profit, salary and dividends, or profit share as the income figure. There is no second year to average, so a strong first year is not reduced by a weaker earlier year, but it is also not supported by a trend.

Some lenders apply lower maximum loan-to-value limits or more cautious affordability to short trading histories, which can reduce the loan available compared with an applicant who has two or more years of the same income. These conditions vary by lender, change over time and are set out in each lender's published criteria for self-employed applicants.

Any early borrowing figure based on a single year's income is an estimate, because the lender's own affordability model and loan-to-value limits decide the final amount.

Credit history is read alongside the short trading record. A clean credit file helps offset the shorter history, while recent missed payments or defaults narrow the lender choice further, because both factors are treated as added risk by the same underwriting team.

The evidence that helps most is the filed tax calculation and tax year overview for the full year, business bank statements showing regular income, and proof of previous work in the same field. An accountant's reference or certificate can also help, and some lenders require one where accounts are short.

Where income has grown during the first year, recent management accounts or invoices can show the current level of trade, although most lenders will still base the offer on the filed figure. Evidence of upcoming contracts or repeat clients supports the case without replacing the filed year.

Brokers who handle short-history cases know which lenders accept one year and on what terms. Firms that work with self-employed clients are listed on the page for self-employed mortgage brokers.
