When applying for a mortgage, “self-employed” is not treated as a single category by lenders.
Sole traders, limited company directors and contractors can all fall under the self-employed umbrella, but the way their income is assessed can differ significantly.
Understanding how lenders typically view each structure helps clarify why documentation requirements vary and why income calculations are not always the same.
This guide explains how mortgage lenders commonly assess income for different types of self-employed applicants.
What Does “Self-Employed” Mean to a Mortgage Lender?
In mortgage terms, an applicant is generally considered self-employed if they:
- Own 20–25% or more of a business, or
- Are not paid solely through PAYE as an employee
This can include:
- Sole traders
- Limited company directors
- Partners in a partnership
- Contractors operating through a limited company
Although these groups are all classed as self-employed, lenders assess their income differently depending on how it is structured and declared.
Sole Traders: How Income Is Typically Assessed
Sole traders are taxed on the profit of their business. Their income is declared through Self Assessment and evidenced using HMRC documentation.
Lenders typically request:
- SA302s
- Tax Year Overviews
For sole traders, lenders usually assess income using the net profit figure shown on the SA302. This represents profit after allowable business expenses.
Where more than one year is required, lenders often compare income across tax years to assess consistency and trends. You can read more about this in our guide on how mortgage lenders average self-employed income (and when they don’t).
Because sole traders are personally responsible for business profits, the net profit figure is generally treated as personal income for affordability purposes.
Limited Company Directors: Salary, Dividends and Company Profit
Limited company directors are taxed differently from sole traders. Their business is a separate legal entity, and income is often structured through:
- Director’s salary (via PAYE)
- Dividends
- Retained company profits
On personal tax documents, income usually appears as:
- Employment income (salary)
- Dividends received
Many lenders assess limited company directors using:
Salary + dividends
These figures are shown on the director’s SA302 and reflect income that has been drawn personally.
However, some lenders may also consider:
- Salary + share of company net profit (after corporation tax)
- Salary + share of company profit before tax
Where company profit is included in the assessment, lenders typically require full company accounts in addition to personal tax documents.
Because income can be structured in different ways, two directors with similar businesses may show different personal income figures on their tax returns.
Contractors: How Income May Be Viewed Differently
Contractor applications can be assessed differently depending on how income is structured and whether taxable income shown on a tax calculation reflects actual earnings.
Contractors can include:
- Contractors operating through a limited company
- Contractors working via an umbrella company
- Fixed-term contract workers paid via PAYE
In some cases, lenders may assess a contractor using their contract rate, rather than relying solely on income shown on an SA302.
Where contract income is used, lenders will typically review:
- The daily or weekly rate
- The number of days contracted to work each week
- The length of the current contract
- Whether the contract is likely to be renewed
Some lenders calculate contractor income by using a formula such as:
Daily rate × days per week × 46–52 weeks per year
This approach is commonly used where the lender’s criteria allows income to be based on the contract value rather than taxable income alone.
Documentation requirements vary between lenders, but contractor applications often involve providing contract evidence in addition to (or instead of) tax documentation.
Why Income Assessment Differs by Structure
The key reason mortgage income rules differ between sole traders, limited company directors and contractors is how income is declared and taxed.
- Sole traders are taxed on business profit.
- Limited companies pay corporation tax, and directors are taxed separately on salary and dividends.
- Contractors may be paid through contracts, PAYE or dividends depending on their structure.
Because lenders rely on declared, taxable income, the format in which income appears on HMRC documents directly affects how it is assessed.

How Many Years of Income Are Usually Required?
Most lenders request at least two years of income evidence for self-employed applicants, although requirements vary.
When multiple years are requested, lenders typically compare figures to assess consistency. In some cases, income may be averaged across years; in others, the most recent year may be used.
Understanding Self-Employed Mortgage Criteria
Although sole traders, limited company directors and contractors are all classed as self-employed, mortgage income rules are not identical across these groups.
Income structure, tax treatment and documentation all influence how lenders assess affordability.

Frequently Asked Questions
How is self-employed income assessed for a UK mortgage?
Self-employed income is assessed by averaging the last two years of net profit (sole traders) or salary plus dividends (limited company directors). Some specialist lenders use the latest year if higher, particularly where income has grown. Contractors are usually assessed on day rate multiplied by 46 weeks, treated as employed income.
How many years of accounts do you need for a self-employed mortgage?
Most high street lenders require two years of full accounts and matching SA302s. Specialist lenders including Kensington, The Mortgage Lender, Aldermore, and Halifax accept one year of accounts for established traders, often at slightly higher rates. Two years is still preferred by most underwriters.
Can limited company directors use retained profit for mortgage affordability?
Yes, with specialist lenders. Halifax, Clydesdale, Kensington, and Saffron Building Society will use net profit retained inside the company in addition to drawn salary plus dividends. This typically increases the qualifying income figure significantly compared with the SA302 amount alone, which only shows what you have personally drawn.
What is an SA302 and why do mortgage lenders need it?
An SA302 is HMRC’s official summary of your declared income for a tax year. Lenders require SA302s alongside Tax Year Overviews to verify the income figure on your application matches what was declared to HMRC. Most lenders ask for the latest two years.
Do mortgage lenders accept self-employed income from a new business?
Some specialist lenders accept self-employed applications with one year of trading where the borrower has previously worked in the same field as employed. Halifax and Aldermore are common choices for these cases. Less than 12 months’ trading is usually only accepted by specialist contract-based lenders or against substantial personal assets.
How much can a self-employed person borrow on a mortgage?
Self-employed borrowers can typically access 4.5x to 5.5x assessed income with high street lenders. Specialist lenders extend to 6x for higher earners or qualifying professionals. Affordability is calculated on the same income basis as employed applicants but lenders will check for declining trends or unusually variable years.
Does the timing of my tax return affect mortgage affordability?
Yes, materially. Once a new tax year ends in April, lenders typically prefer to use the latest year’s income from January onwards once HMRC has processed the return. Submitting the new tax return early can unlock higher affordability if your income has grown. Delaying past January means lenders may still treat the prior year as the base figure.
Can I get a mortgage with one year of self-employed accounts?
Yes, with specialist lenders. Aldermore, Kensington, The Mortgage Lender, and Halifax will lend against one year of full accounts where the borrower has a clear track record in the same field beforehand. Rates are typically 0.2 to 0.5 percent above standard self-employed products.
