Self-employed income evidence
One year of accounts, but no SA302?
First find out why the tax calculation is missing. You may be able to retrieve it, obtain the calculation produced by your accountant’s software, or need a different evidence route that the proposed lender expressly accepts. One year’s accounts and a missing SA302 are two separate checks.
Can you apply without an SA302?
Possibly, but there is no general rule that accounts, bank statements or invoices can replace a requested tax calculation.
Some UK lenders consider applicants with one completed year of self-employment. Each lender also sets its own rules for verifying the income it will use. The first useful question is whether a tax calculation exists but has not been retrieved, or whether no completed Self Assessment return has produced one yet. If the proposed lender requires a particular record, supporting documents do not automatically remove that requirement.
Why do you not have an SA302?
Choose the situation closest to yours. This is a document-finding guide, not a lender eligibility decision.
You filed through HMRC online
Check your online Self Assessment account for the relevant tax calculation and tax year overview. HMRC explains where to find them and when they become available after filing. Check that the year matches the records the lender has requested.
Your accountant used commercial software
Ask your accountant for the tax calculation produced by that software; it may be called a tax computation. The matching tax year overview can be obtained through your HMRC online account. Confirm that the lender accepts the format before submitting it.
Your first return has not been filed
You cannot retrieve a tax calculation for a return that has not been submitted. Ask your accountant when an accurate return can be filed and what completed business records are available now. An adviser can check whether any lender has a suitable evidence route; do not assume a forecast or bank statements will suffice.
The figures or dates do not match
Check whether the accounts year and tax year cover different periods, a return was amended, or income changed after the year end. Ask your accountant or HMRC to explain or correct the records as appropriate. Tell the adviser about the discrepancy before an application.
Use HMRC’s current instructions for obtaining a tax calculation and tax year overview. HMRC says you should check that the mortgage provider accepts documents you print yourself.
Does your one year of accounts cover a full trading year?
A first set of accounts, a filed tax return and twelve months of trading may refer to different periods. For example, a sole trader who started in October could have a tax return to the following April covering only part of their first trading year. A completed business year later on does not automatically mean the lender will treat that earlier tax return as twelve months of income.
Write down the trading start date, accounting year end, tax year covered and any recent change in income. If you moved from sole trader to limited company, note when and why the structure changed. These dates help an adviser identify the relevant criteria without assuming the answer from a document label.

What should you prepare before seeking advice?
- Describe the gap. Say whether the calculation has not been downloaded, was produced in software, has not yet been created, or contains a discrepancy.
- List the periods. Note your business start date, completed accounts period and the tax year of any submitted return.
- Identify your income route. Say whether you are a sole trader, partner, limited company director, contractor or CIS worker. Salary, dividends, business profit and contract income may be assessed differently.
- Keep supporting records ready. Accounts, statements, contracts or CIS records may help explain current trading where requested. Their role depends on the lender; none is a universal substitute for a required calculation.
- State your mortgage purpose. Buying, moving and remortgaging can have different timing pressures. If another lender declined or rejected evidence, share its stated reason if known.
There is no need to send tax references, bank details or document copies with your initial enquiry. Ask your adviser for a secure way to provide records after they have identified what is needed.

Questions when the tax calculation is missing
Is an HMRC tax year overview the same as an SA302?
No. They are separate records. Ask for the tax calculation or accepted software equivalent and the matching overview if the lender requests both.
Can my accountant provide the calculation?
If your return was filed with commercial software, ask your accountant for the calculation produced by that software. Confirm the lender’s accepted format and any requirement for a matching HMRC overview.
Are business bank statements enough without an SA302?
Not automatically. Statements may help show current trading, but whether they form part of an acceptable income-evidence route depends on the lender and your circumstances.
What if I have not filed my first tax return?
Be clear about the trading period already completed and ask your accountant when an accurate return can be filed. An adviser can check current lender policy, but a first year’s accounts do not by themselves guarantee a route without a tax calculation.
Does a larger deposit solve a missing-document problem?
No. A deposit can affect the mortgage products available, but it does not replace the income verification the lender requires.
