Prepare the right income evidence for your self-employed mortgage.
You may be asked for tax calculations, tax year overviews, business accounts and bank statements. The exact list depends on how you work, how long you have traded and the lender’s assessment.
Use this guide to understand what each record shows, spot gaps early and prepare for a conversation with Count Ready.
See the preparation checklistAsk about your income evidenceWhat proof of earnings might a lender ask for?
These records answer different questions. You may not need every item below, and one document does not automatically replace another. Ask for a case-specific list showing the required years, statement periods and acceptable formats.
Tax calculation: SA302 or software equivalent
This sets out the income reported through Self Assessment and the resulting tax calculation for a particular tax year. It is not a business bank statement or a record of company turnover.
If you filed through HMRC, use your online Self Assessment account. If your accountant used commercial software, ask for the calculation produced by that software.
HMRC tax year overview
This is a separate HMRC record of your tax position for the year. A lender may request it alongside the tax calculation, including where the calculation came from your accountant’s software.
Check that the tax years match. If the records appear inconsistent, ask your accountant or HMRC to explain the difference before submitting them.
Final business accounts
Accounts show business performance over an accounting period. The lender may need the full accounts, including the profit and loss account and balance sheet, rather than the abbreviated information available publicly.
Confirm whether the lender requires an accountant to prepare or certify them, and which professional qualifications it accepts.
Personal and business bank statements
Statements help a lender understand recent trading, income received, spending and commitments. Turnover entering a business account is not automatically personal income available for mortgage payments.
Provide the requested consecutive periods with all pages. Explain unusual credits, transfers, loans or seasonal changes honestly.
Accountant’s reference or certificate
A lender may request its own form confirming specified income figures, ownership and trading information. A general letter saying the business is doing well may not meet that requirement.
Check the form and accountant requirements before commissioning extra work. A projection is not the same as completed accounts.
Contracts and other supporting records
Depending on your work, these could include signed contracts, payslips, CIS payment and deduction statements or dividend records. They help explain the source and continuity of earnings.
Their role depends on the lender’s income assessment. An invoice or future contract alone does not establish an acceptable mortgage income.
For the current retrieval instructions, use HMRC’s guide to getting your tax calculation and tax year overview. Check the lender accepts the format you obtain.
For help reading the income entries, see our explained SA302 example.
Start with how your business pays you
A job title such as “freelancer” does not explain the whole position. Tell your adviser whether you trade personally, through a partnership or through a limited company, and whether an agency or umbrella company pays you.
Sole traders and freelancers
Prepare records that distinguish sales from business profit. Tax calculations, matching overviews and accounts may be relevant, with recent statements showing current trading. Explain any other income separately.
Partners and LLP members
The lender needs to understand your share of income, rather than treating the whole partnership’s turnover as yours. Gather personal tax records and be ready to evidence your profit share through accounts or an accountant’s confirmation.
Limited company directors
Identify salary, dividends and company profits separately. Depending on the lender, personal tax records, company accounts and ownership evidence may be needed. A payslip alone may not be sufficient where you own part of the business.
Some assessments can consider a share of company profit; others focus on salary and dividends. Read our director mortgage guide.
Contractors and CIS workers
Explain the contract arrangement, payment method and any gaps between assignments. Contract-based assessment may require current and previous contracts; PAYE or umbrella work may require payslips. CIS workers should have payment and deduction statements available.
Ask which route applies before assuming a day rate, gross CIS receipts or accounts will determine the income used.
For a joint application, organise evidence for each applicant separately. If you have both employment and self-employed earnings, identify both sources and explain any overlap. For broader eligibility questions, visit our self-employed mortgages page.
Check dates, trading history and changes in income
There is no single evidence period for every self-employed application. A lender may request several completed years, while some routes can consider a shorter history. The age of the latest accounts and what has happened since their year end can also matter.
If you have only one completed year, see our guide to mortgages with one year’s accounts. A larger deposit does not remove the need to meet the relevant trading and income criteria.
Illustrative document check
A director has company accounts ending 31 December 2025 and personal tax documents for 6 April 2025 to 5 April 2026. These cover different periods, so the figures may not line up directly.
The practical next step is to label both periods and ask the accountant to explain the salary, dividends and company income recorded in each. This example is about organising evidence, not a lender decision or borrowing estimate.
If profits have fallen or changed sharply, prepare a short explanation supported by records. Seasonal trading, a lost contract, a one-off expense or time away from work may need different evidence. Do not assume a lender will average the figures or ignore the lower year.
If you changed from sole trader to limited company, provide the dates and records from both arrangements. Tell your adviser about changes in ownership or activity too. Business continuity needs to be assessed; a new company registration does not tell the full story.
Missing a document? Explain what is available and why something is missing. Alternative evidence may be acceptable for a particular lender, but this is not a route to an unverified residential mortgage income.
Your income evidence preparation checklist
Use this as a starting point for your adviser’s document request. You can copy or print the list for your own records; it is not an application form.
- Describe your work: business structure, ownership, trading start date and any recent changes.
- List available periods: completed accounts years, tax years and the latest statement dates.
- Pair requested tax records: the calculation and overview for each relevant tax year.
- Keep full documents: complete accounts and consecutive statement pages in the format requested.
- Separate income sources: salary, dividends, profit share, contracts and any employment income.
- Explain differences: declining profits, unusual credits, gaps in work or mismatched periods.
- Confirm what is missing: ask your accountant or adviser before ordering replacement records or additional reports.
- Agree a secure handover: check the recipient and the requested upload method before sending financial documents.
Keep original files and use clear filenames with the applicant, document type and period. Do not edit figures, remove pages or conceal transactions. Ask about an accepted alternative if a document cannot be supplied.
You will also need to address identity, deposit source, expenditure and other commitments. This checklist focuses on income evidence and does not replace the complete application requirements.
How Count Ready can help you prepare
- Explain your plans. Tell us whether you are buying, moving home or remortgaging, how you work and how long you have traded.
- Review the evidence available. Your adviser can discuss the income sources and gaps that may affect the options considered.
- Check the relevant requirements. Before an application, confirm the lender’s current evidence criteria and any additional documents needed.
If another lender has declined an application or rejected documents, tell us the reason given and the stage reached. Further advice does not guarantee a different outcome, but the explanation can help establish what needs to be checked before another application.
Count Ready provides mortgage advice by phone and online. Fees will be agreed before chargeable work begins; see our Terms of Business. Your accountant remains the appropriate person to explain or correct tax and accounting records.

Questions about self-employed mortgage documents
Is a tax year overview the same as an SA302?
No. A tax calculation shows the income and tax calculation for a tax year. A tax year overview is a separate HMRC record of the tax position for that year. If a lender requests both, supplying one does not replace the other.
Can I use a tax calculation from my accountant?
A calculation produced using commercial tax software may be acceptable. Ask your adviser to check the lender’s document requirements and whether a matching HMRC tax year overview is needed. Do not substitute an informal income summary.
Do I need both accounts and tax calculations?
Not in every case. The evidence route depends on the lender, your business structure and the income being assessed. Confirm the required documents and periods before paying for additional accounting work.
Are business bank statements enough on their own?
Do not assume so. Bank credits can include transfers, loans and other receipts that are not earnings. Statements usually support the wider assessment; ask which additional income records the lender requires.
What if I have not filed my first tax return?
Explain when trading started and which final accounts or other records are available. A lender may have an alternative evidence route, but a missing tax return does not remove income verification or trading-history requirements. Do not submit estimated income as if it were verified.
Will a remortgage need new income evidence?
A remortgage to another lender will normally involve a fresh assessment. A product transfer with your existing lender can have different requirements, particularly if you are not borrowing more or changing the mortgage. Check the proposed transaction before gathering documents.
Should I upload financial documents with my first enquiry?
Start with a brief description of your business structure, trading history and mortgage plans. Do not put tax references, bank details or document copies into a general enquiry message. Ask your adviser how to provide requested evidence securely.
