Secured loans for the self-employed: how to prove your income

What income is the lender trying to establish?

A lender needs to understand how much income you earn, whether the evidence supports it and whether it is likely to continue. It must verify income and assess affordability for the regulated mortgage borrowing covered here. Equity cannot replace those checks.²

Start by separating four figures:

1. Turnover, meaning the value of your business's sales over a period.
2. Business profit after relevant expenses.
3. Income attributable or paid to you personally.
4. Money available after tax, household spending and existing repayments.

These figures answer different questions. A high sales total can sit alongside expensive materials, wages or premises.

For example, suppose a sole trader has £90,000 of turnover and £35,000 of business expenses, leaving £55,000 before personal tax in this simplified example. £90,000 is not their personal earnings. Nor does the £55,000 establish how much mortgage borrowing they can afford.

Actual tax calculations can involve adjustments, so use your completed records rather than treating this example as a tax calculation. HMRC requires business income and expense records, with the applicable accounting method affecting how figures are recorded.³

How your business structure changes the evidence

Sole traders and partners

A lender may assess a sole trader using business profit, with personal tax documents and accounts supporting the figure. For a partnership, your own share of earnings matters.

The lender can also decide which period to use. Some assessments use an average; others consider the latest figures or take a cautious view where earnings have fallen. There is no calculation that every provider applies.⁴

Ask the broker to identify the income figure entered on your application. This is especially useful if your accountant's profit figure and the amount you regularly transfer into your personal account differ.

Limited company directors

Paying yourself through PAYE does not necessarily mean the lender will assess you like an employee with no ownership interest. The lender may look at your shareholding and the company's finances as well as your salary.

Depending on its criteria, a lender may use salary and dividends or consider an appropriate share of company profit. The treatment of retained profit varies.⁴ Do not assume that the entire company bank balance is available to support your personal borrowing.

Salary, dividends and directors' loans are different ways money can leave a company. Dividends must be supported by available profits, and money withdrawn outside salary, dividends or legitimate expense repayment may create a director's loan.⁵

Give the broker your ownership percentage and explain how you receive income. Ask your accountant to clarify unusual withdrawals rather than describing every transfer as earnings.

Contractors and freelancers

A contract, day rate or invoice can help explain your work, but it does not automatically establish an annual income the lender will accept.

Some mortgage lenders consider contract earnings; others assess the accounts and tax history.⁴ Ask what evidence is needed for gaps between contracts, renewals and the way your work is paid. Explain whether you operate personally, through a company or through an umbrella arrangement.

Which documents should you prepare?

Ask for a list tailored to the proposed lender before paying for new reports or certificates. The examples below show what different records can help establish. They are not a requirement to provide every document.⁶

You will also need to address the ordinary application checks, including identity, address, ownership and your existing mortgage. Have the latest mortgage statement and details of other borrowing ready.⁷

A lender may request more evidence if the documents cover different periods or raise unanswered questions.

How to get your SA302 and tax year overview

An SA302 is a tax calculation, not a copy of the complete Self Assessment return. HMRC says you can obtain calculations for the last four years after submitting your returns, and a tax year overview for any year.⁸

If you file through HMRC's online service, use your account to obtain the relevant documents. If your accountant uses commercial software, the tax calculation may need to come from that software, while the overview is available through HMRC.

Check that the mortgage provider accepts the format supplied. HMRC says documents cannot be printed until 72 hours after submitting the return.

Keep each calculation with the overview for the same tax year. Ask your accountant to explain any discrepancy before submission. Do not assume a screenshot showing a refund or payment replaces either document.

How many years of accounts do you need?

There is no universal minimum for every secured loan. The requirement depends on the lender, product, business history and evidence available.

For example, a current second charge lender's guidance uses different evidence routes involving tax calculations, corresponding overviews or an accountant's certificate. It also sets conditions around the age of documents and recent trading evidence.⁹

A shorter trading history can limit the available options. Ask the broker whether a lender will consider the history you actually have, including any relevant previous work.

If you recently moved from sole trader status to a limited company, explain the dates and whether the underlying business changed. Prepare records from both periods. Do not assume the old and new figures will automatically be combined.

What if income fluctuates or has recently fallen?

Explain the cause with evidence. A seasonal business, a period of illness and the loss of a major customer create different questions.

Prepare a short timeline showing the change, its effect and the documents that support your explanation. Separate work already completed from forecasts and hoped for contracts.

A strong earlier year does not cancel a weaker current position. Lender guidance can require an explanation of falling earnings and use the lower figure when assessing the case.⁹

For your own budget, look beyond the annual total. Ask whether quieter months leave enough money for the existing mortgage, proposed loan, tax and essential spending. A payment collected every month still needs funding when customers pay late.

If repayments depend on future sales that are not yet secured, reconsider the amount or timing before applying.

Can you apply without an accountant?

Not every acceptable evidence route requires a new accountant's certificate. Some lenders accept suitable tax calculations and other records, while particular cases require professionally verified figures.⁹

Ask which route is available before commissioning extra work. If a certificate is needed, establish whether the lender specifies a template, recognised qualifications or direct contact with the accountant.

You still need accurate evidence. The lender cannot simply accept an unsupported income declaration for the ordinary regulated mortgage described here.²

Where you prepare your own accounts, keep a clear route from business records to the figures supplied. If something needs correction, deal with it properly with HMRC or your accountant.

What else affects the decision?

Income is only part of the application. The lender will also assess the home, existing secured borrowing and your financial commitments.

Working for yourself does not remove the need to meet the lender's credit and property criteria. A particular income assessment may be acceptable while the requested amount is not. Avoid assuming that approval from one provider means another will reach the same result.

Before choosing a loan, compare the full cost, fees, repayment term and alternatives with an adviser. A further advance or remortgage may deserve consideration, alongside an unsecured loan or postponing the expense.¹

Ask for the personalised mortgage illustration and check the cash you receive against the total amount borrowed. Fees added to borrowing can attract interest. A longer term can reduce monthly payments while increasing the overall cost.¹⁰

A practical preparation checklist

Before your first detailed conversation:

1. Write down your business structure, ownership share and trading start date.
2. List each source of personal income separately.
3. Gather the latest completed accounts and relevant tax documents.
4. Check the requested statement periods and supply complete, readable files.
5. Prepare a factual explanation of changes in earnings or business structure.
6. Keep tax commitments and quieter trading periods in your household budget.
7. Ask what credit search will occur before a formal application.

Habitat Loans introduces customers to Loans Warehouse for mortgage advice and arranging services. Explain how your income is earned at the outset, so the broker can assess the available options using the right evidence.

The useful question is not simply how much your business makes. It is which income a lender can verify, and whether the resulting repayment remains manageable for your household.
