One Year of Accounts: Self-Employed Mortgage Evidence

One year of accounts can provide a useful record of a business’s first trading period. It does not answer every question a mortgage lender asks about income or establish that the available history meets every lender’s requirements.

The practical starting point is what “one year” means in your case: when trading began, the period the accounts cover and whether they are final. A clear timeline is more useful than assuming all short-history applications are treated alike.

One set of accounts can cover different periods

The following examples are fictional. They explain dates rather than eligibility or a lender’s accepted income calculation.

HMRC explains the tax-year dates and how to obtain tax calculations and overviews in its SA302 guidance. An SA302 and a tax year overview are separate records; the requested years and acceptable format should be confirmed for the case.

Published lender examples: why one year is not a universal rule

Policy examples checked 2 November 2026. These are limited illustrations of published criteria, not an exhaustive comparison, product recommendation or confirmation that either lender will accept an application. Check the full current policy and relevant product before relying on it.

Match each document to the question it answers

For example, a business’s £60,000 sales, £35,000 costs and £25,000 profit are three descriptions of the same trading period, not £120,000 to add together. Drawings or transfers to the owner need to be understood within the business structure; they do not automatically create additional profit. This arithmetic example does not specify which figure a lender will accept.

One year of accounts: Establish the actual trading period

Visual explanation: one year accounts

Record the date the business began trading and the start and end dates of the accounts. The date a company was incorporated is not necessarily the date its activity began.

A first set of accounts can cover more or less than twelve months. Do not describe a short period as a complete year simply because it is the first set prepared. The dates determine what the figures represent.

Separate accounts from personal tax years

Business accounts and personal tax records can describe different periods. A company may have a financial year end that differs from the personal tax year.

Put the relevant dates beside each document. A tax calculation, tax year overview and set of company accounts should not be expected to contain interchangeable figures merely because they relate to the same person.

Understand why lender policies differ

Lenders set their own trading-history and evidence requirements. Halifax publishes criteria allowing consideration after at least one full year in defined circumstances, with individual assessment. Nationwide’s published self-employment evidence requirements describe two years.

These examples illustrate different approaches rather than recommend either lender. Meeting a minimum-history condition does not establish that the income, property and rest of the application will be accepted.

Identify the income relevant to your structure

For a sole trader, turnover and profit are different figures. For a partnership, your share needs to be distinguished from the business total. A company director’s salary and dividends are different from company receipts.

An adviser needs to establish the lender’s assessment method. Do not add every amount across accounts and tax records: the same income can appear in more than one place.

Keep final results separate from drafts

A draft set of accounts, management information and a forecast describe different stages of information. Label each accurately and identify who prepared it.

An accountant’s forecast may explain expected activity, but it does not turn future receipts into completed earnings. Ask which documents the potential lender requires and whether the available final records meet those requirements.

Explain earlier work in context

Previous employment or work in the same occupation may help describe your experience. Keep the dates and nature of that work clear.

Earlier salary does not automatically become current self-employed income. It can provide background without being added to the new business profit as if both were ongoing at the same time. The lender’s method governs the relevant calculation.

Describe a change in business structure

If you previously traded as a sole trader and now operate through a company, distinguish the overall trading history from the age of the company. The records should show when each arrangement applied.

A structural change may be treated differently from a completely new activity, depending on lender criteria. It does not justify combining overlapping periods or assuming every lender will regard the history as continuous.

Bring recent trading up to date

The latest accounts end at a particular date. A lender may need further evidence about the period since, such as business statements or current financial information.

Explain material changes, including reduced work, a new business activity or an important contract ending. Current receipts can help describe trading, but they do not automatically increase the annual income used for affordability.

Example: twelve months followed by further trading

Imagine a designer has final accounts for twelve months and then trades for another four months before enquiring about a mortgage. They organise the completed accounts separately from the newer statements.

The completed period establishes historical results; the later records help explain what happened afterwards. Neither should be silently annualised or merged to create a figure unsupported by the lender’s calculation.

Prepare the requested evidence

Depending on the lender and arrangement, useful records may include:

• Finalised accounts with clear period dates.
• Requested tax calculations and matching overviews.
• Business and personal statements.
• Ownership and trading-start information.
• An explanation of changes since the accounts date.

HMRC provides guidance on obtaining tax calculations and overviews. An adviser can establish which years and document formats the lender accepts.

Keep the rest of the application in view

A short trading history is only one factor. Household spending, borrowing, the deposit source, the proposed property and other relevant circumstances remain part of the assessment.

There is no universal deposit percentage that overcomes income evidence requirements. Whether applying now or later fits your situation requires personal mortgage advice, rather than a fixed waiting rule in a general guide.

Frequently asked questions

Does one set of accounts always represent a full year of trading?

No. Opening accounting periods vary. Check the actual start and end dates and when the business began trading.

Will every lender consider an application with one year of accounts?

No. Trading-history and evidence policies differ. Any lender considering the case still assesses the wider application.

Can a forecast automatically be added to completed earnings?

No. Forecasts concern expected activity. The lender decides which evidenced income it accepts and how it calculates affordability.

Important information and Mortgage Bridge’s role

Mortgage Bridge provides general information and administrative support as a mortgage introducer. It does not provide mortgage or debt advice, assess eligibility, affordability or suitability, or recommend products. Mortgage advice comes from an adviser acting through an FCA-authorised and regulated network.

Mortgage Bridge has commercial relationships with receiving firms and receives a percentage of the adviser’s commission when an introduced case completes.

Your home may be repossessed if you do not keep up repayments on your mortgage.

Securing previously unsecured debts against a home increases the risk to the home. Lower monthly payments do not necessarily mean lower total costs. Longer repayment terms and fees can increase the total amount repaid.
