Which figure can a lender use?
Turnover, drawings and money in a business account are not interchangeable with mortgage income. Start with how you trade, identify the figures you can evidence, then consider affordability.
- Which business or payment structure applies to you?
- What do completed tax records, accounts or contracts show?
- How do debts, household costs and the proposed mortgage fit together?
This is a guide to the questions, not a lender affordability calculation.
How is self-employed income calculated for a mortgage?
A lender first decides which income measure its policy accepts for your circumstances. That might be a sole trader’s net profit, a partner’s attributable income, a director’s salary and dividends, or a method based on a qualifying contract. It then checks the supporting records and considers affordability, credit, commitments, the property and the mortgage sought. There is no calculation that all UK lenders apply to every self-employed applicant.
This guide explains the figures and questions. For the full application journey, see our self-employed mortgage advice page.
How does your business structure affect the income assessment?
The right starting figure depends on the legal arrangement and the way you are paid. “Self-employed” is useful shorthand, but it does not tell a lender whether to read a tax calculation, company accounts or a contract.
| How you work | Figure to discuss | Important distinction |
|---|---|---|
| Sole trader | Net trading profit shown in the relevant tax records. | Turnover is sales before allowable business costs. Drawings are transfers to you, not a second income stream. |
| Partner or LLP member | Your attributable profit share or remuneration, according to the arrangement. | Partnership turnover is not your personal income. An LLP salaried member may be paid differently from a profit-sharing member. |
| Limited company director | Often salary and dividends; some policies may consider an attributable share of company profit. | Retained company cash is not automatically personal income. Do not add dividends and the same underlying company profit twice. |
| Contractor or freelancer | Depends on whether you are paid through PAYE, an umbrella, sole trade or a company. A contract-based method may be available under some policies. | A day rate is not an automatic annual salary; work pattern, gaps, contract terms and evidence matter. |
| CIS subcontractor | Taxable trading profit or a CIS-specific method where a lender’s current policy permits it. | Gross voucher payments and the figure after CIS deductions need careful explanation; neither automatically becomes accepted mortgage income. |
These are starting points, not promises that a particular lender will use a figure. Shareholding thresholds, acceptable evidence and product rules vary. Ask an adviser to check current criteria before relying on a calculation.
A sole trader who transferred £50,000 from the business account has not created another £50,000 of earnings. The example is invented to show the distinction. It is not a tax computation, lender-approved income figure or borrowing estimate.
What if the last two years tell different stories?
Some lenders consider an average of completed years; others may use a more recent figure or apply a different approach. A fall can prompt questions about whether the business can sustain the proposed mortgage. A rise may need evidence that new work or improved profit is continuing. No applicant should assume the highest year will be used.
Explain why profit grew
Was it a new long-term client, a price change or a one-off project? Show the completed figure and the current position, while allowing the lender to decide how much weight to give the rise.
Explain why profit fell
Separate a lost contract or recurring costs from a documented exceptional expense. The lender may still rely on the lower figure. Our fluctuating-income guide helps you prepare the timeline.
If you only have one completed year, use the existing one-year accounts guide. That is a separate eligibility and evidence question; one year is not an automatic refusal or acceptance.
Does an income figure tell me how much I can borrow?
No. Once a lender has identified income it can use, it assesses the requested loan against the household’s commitments and its lending rules. Existing credit payments, dependants, regular spending, the mortgage term, deposit, interest-rate assumptions and property can all affect the answer. A joint applicant’s employed salary may be considered too, but each person’s evidence and commitments still need checking.
About Count Ready’s calculator: the existing mortgage affordability calculator asks for “Main Income Annual Gross”. It does not identify your business structure or decide which self-employed figure a lender would accept. Do not enter turnover as if it were salary, or treat its maximum result as an offer. If you are unsure which income to use, ask for advice before relying on a figure.
There is no universal borrowing multiple for self-employed applicants. A worked multiple can make arithmetic look certain while concealing the income and affordability decisions that come first.
What records help an adviser check your income?
Start with records you already have. The application-stage list depends on the lender, business structure and recent changes; do not assume every item below is required in every case.
Tax calculation and overview
An SA302 or equivalent tax calculation shows the income and tax calculation for a filed year. A tax year overview is a separate HMRC record. Check that the names, years and figures match. Our SA302 guide explains the difference.
Profit and company position
Accounts can explain completed trading periods, expenses and, for a company, salary, dividends or retained profits. An accountant may need to clarify a structure change or unusual item if the lender requests it.
Contracts and recent trading
Invoices, contracts, CIS statements or management information can help explain a recent change. They do not automatically replace completed tax or accounting evidence.
Income alongside commitments
Be ready to describe other employment income, regular debts and the mortgage purpose. On a joint application, keep each applicant’s income and documents separate.
See the self-employed proof-of-earnings checklist for a fuller document guide. HMRC explains how to obtain tax calculations and tax year overviews; availability after filing is time-sensitive and the lender must confirm what it accepts.
Prepare the facts, then ask the right question
This worksheet is a prompt for your own notes, not an upload form or a substitute for advice. You can describe the position in an initial enquiry without sending account numbers, tax references or document copies.
How are you paid?
Note whether you are a sole trader, partner, director, contractor, CIS worker or have mixed PAYE and business income. Record any recent change in structure.
Which years are complete?
List the tax or accounting years you can evidence and whether profit rose, fell or remained steady. Record the reason for a significant change.
What are you planning?
Say whether you are buying, moving or remortgaging; whether there is another applicant; and whether you need a decision soon or are preparing ahead.
Count Ready can use that outline to explain the advice process, likely evidence questions and case-specific next steps. The lender ultimately decides which income and mortgage it will accept. We explain fees before chargeable work; the published Terms of Business sets out the stages and conditions.
Self-employed mortgage income FAQs
Is turnover the income a mortgage lender uses?
Usually not for a sole trader: turnover is sales before business costs. A lender assesses the income measure permitted by its policy, supported by the relevant tax or accounting records. Ask an adviser which figure applies to your structure.
Do personal drawings count as extra income?
No. Drawings move money from a business to its owner; they do not create another stream of profit. The lender will look at the underlying evidenced income and its own policy.
Can a director use retained company profits?
Some lender policies may consider a relevant share of company profit, while others focus on salary and dividends. Ownership, accounts, sustainability and product rules matter. Retained cash cannot simply be added to salary and dividends as a universal formula.
Will a lender average two years of profit?
It may, but not every lender or product uses the same years or method. A rising or falling trend can change the assessment. The adviser needs the completed figures and the reason for any significant change.
Can I combine PAYE and self-employed income?
A lender may consider more than one evidenced income source, subject to its criteria and whether the work is sustainable. Keep payslips and business records distinct. The same principle applies when one joint applicant is employed and the other is self-employed.
Can I work out my maximum mortgage from a multiple?
A simple multiple is not a reliable lender decision. The lender must first decide which income it accepts, then assess affordability, credit, commitments, the property and product rules. A calculator result is only a starting estimate.
