The short answer
Self-employed applicants can prepare for a Scottish mortgage by explaining how their business income is earned and by supplying consistent, complete evidence. Sole traders, partners and limited-company directors may be assessed differently, and no single approach to salary, dividends, net profit or retained profit applies everywhere. Accounts, tax documents, statements and current trading evidence help explain the picture.
What this guide covers
“Self-employed” is not one income type. A sole trader, a partner and a director who owns shares in a limited company can have different accounts, tax records and ways of drawing money. Lenders and intermediaries set their own criteria and may ask for different periods or documents. The points below are a preparation framework, not a promise that any lender will count a particular figure.
Sole traders
Prepare the accounts and profit information requested for the relevant completed periods; the accounting basis and treatment of expenses vary, so confirm the required format. A lender may look at one or more years, trends, the latest year and the reason for any change; the precise calculation varies. Do not assume that turnover, drawings, taxable income or net profit will be used in the same way by every lender.
Partnerships
Have the partnership accounts and the applicant’s share of profit available, alongside personal tax calculations and evidence of drawings where relevant. Explain the partnership agreement, ownership share, changes in partners and any unusual distributions. The treatment of a partner’s profit share, salary or drawings is policy-dependent, so ask what the assessing organisation needs before presenting one figure as “income”.
Limited-company directors
Prepare company accounts and personal records that show the relationship between the business and the individual. Evidence may include salary, dividends actually declared and received, shareholding, and the company’s current position. Some assessors may consider different elements or retained profit; others may not, or may require additional evidence. There is no universal rule that salary, dividends, net profit or retained profit will be accepted or combined in a particular way.
Evidence checklist
Ask in advance which format, period and accounting basis are required. Depending on circumstances, prepare:
- signed or submitted business accounts and, where requested, accountant details or notes;
- SA302 tax calculations (tax calculations) and HMRC tax-year overviews for the years requested;
- personal and business bank statements showing income, transfers, drawings, tax payments and regular commitments;
- payslips and dividend vouchers or declarations where relevant to a director;
- partnership agreement, shareholding information and explanations of changes in ownership;
- evidence of ongoing contracts, invoices, pipeline or trading where a recent change needs context;
- proof of tax paid or payment arrangements, with an explanation of any arrears rather than omission;
- photo ID, address history, deposit/source-of-funds evidence and details of credit commitments, where requested;
- a clear written explanation for gaps, one-off costs, large credits, falling profit or unusual transfers.
HMRC guidance accessed on 17 September 2026 says an SA302 can be obtained for the last four years after a Self Assessment return is sent, and a tax-year overview can be obtained for any year; check the current guidance before relying on that period. HMRC currently says you cannot print the documents until 72 hours after sending the return; check that the recipient accepts self-printed copies. Follow HMRC’s current instructions rather than an old broker checklist: Get your SA302 tax calculation.
Fluctuating or recently changed income
Record the dates and amounts of material changes: a new contract, lost contract, seasonality, parental leave, illness, a one-off expense, a change in drawings or a change in company remuneration. Reconcile accounts to tax records and statements. Include current management information only if it is genuine and can be evidenced. A strong recent month does not erase a longer trend, and a weaker year should not be hidden; ask how the complete history will be interpreted.
MoneyHelper’s mortgage affordability guidance explains that income and monthly outgoings inform how much someone may be able to borrow. It is consumer guidance, not a lender decision or guarantee. Affordability also depends on commitments, deposit, term and the assessing organisation’s process.
Preparation checklist
- Identify your structure, ownership percentage and how money reaches you.
- List completed accounting and tax years, with gaps and changes dated.
- Obtain the requested accounts, SA302s and tax-year overviews directly from the relevant records.
- Reconcile business and personal statements to declared income and explain transfers.
- Separate salary, dividends, drawings, profit and retained business funds; do not label one as another.
- Gather current trading evidence and explain seasonality or a changed contract.
- List debts, commitments, dependants, tax payments and any arrears accurately.
- Ask the intermediary or assessing organisation what it counts, what period it needs and what evidence format it accepts.
- Keep a dated document pack and send complete pages, not selected extracts.
- Recheck figures and dates before sharing; seek regulated advice for an individual assessment.
Hypothetical scenarios (not outcomes)
These examples are deliberately illustrative. They contain no approval, lender, rate, borrowing multiple or recommendation.
Scenario A — sole trader
Applicant and dates: “Aisha”, sole trader electrician; accounts to 31 March 2024 and 31 March 2025; Self Assessment returns filed 20 January 2025 and 18 January 2026. Declared net profit: £34,800 (2024) and £41,200 (2025). A large van repair cost £6,000 was paid in November 2025; January–August 2026 business-account credits total £58,400.
Questions/evidence to prepare: Which profit years and accounting treatment are requested? Obtain both accounts, SA302s and tax-year overviews; mark the repair invoice and payment; provide January–August 2026 business statements, invoices and contract evidence; explain seasonality and tax payments. Do not present the £58,400 credits as profit without reconciling expenses.
Scenario B — partnership
Applicant and dates: “Ben”, 50% partner in a design partnership; accounts to 30 June 2024 and 30 June 2025; personal tax returns filed 12 January 2025 and 10 January 2026. His profit share was £28,000 (2024) and £36,500 (2025); the partnership admitted a new partner on 1 July 2025. Personal drawings were £2,000 per month from July 2024 to June 2025.
Questions/evidence to prepare: Does the assessment require partnership profit share, drawings or another measure? Supply both partnership accounts, agreement and ownership change, Ben’s SA302s and tax-year overviews, and business/personal statements showing drawings. Explain why drawings differ from profit and provide current trading information through the latest available period.
Scenario C — limited-company director
Applicant and dates: “Cara”, 75% shareholder and director of a web studio; company year ends 31 December. Company accounts show net profit £62,000 (2024) and £74,000 (2025). Her salary was £12,000 each year; dividends declared and paid were £18,000 (2024) and £24,000 (2025). The company retained £30,000 at 31 December 2025; management accounts to 31 August 2026 show turnover £210,000 and net profit £39,000.
Questions/evidence to prepare: Which elements, if any, will be considered and what evidence supports them? Provide company accounts, personal SA302s/tax-year overviews, payslips, dividend vouchers/declarations, business and personal statements, shareholding records and current management accounts. Ask how retained profit and current trading will be treated; do not assume that company profit is personal income.
