SA302 evidence covers the last four tax years
That gives you a firm starting point for income proof instead of relying on screenshots, draft accounts or verbal estimates.

Get the paperwork, lender checks and adviser checks in the right order before you apply, so sole traders, partners, company directors and contractors can turn business income into a cleaner mortgage case.

HMRC Proof
SA302 evidence is available for the last 4 tax years
HMRC Timing
Tax documents cannot be printed until 72 hours after filing
Lender Reality
Published self-employed criteria still vary materially between lenders
Evidence First
What you can prove before a lender even reviews the case
The strongest self-employed applications usually start with clean, current evidence rather than with a broad affordability guess.
Tax year overviews still matter
Mortgage lenders often want the tax year overview alongside the SA302 so they can see the return and the related tax position together.
There is a built-in 72-hour delay after filing
If the latest return has only just gone in, do not promise documents immediately. Build the HMRC delay into your application timing.
Printed HMRC documents can work, but lender checks still matter
HMRC lets you print the tax calculation and tax year overview yourself. Before you apply, confirm that the lender or broker is happy with the exact document set you plan to use.
Published Examples
Why self-employed lending cannot be reduced to one generic rule
These examples show why a borrower should match the case to lender criteria rather than assume every lender will view the same income in the same way.
Nationwide: limited company directors
Published criteriaNationwide uses the lower of the most recent year's salary and dividends or the average of the last two years in several limited company director cases. Its published criteria also require the latest year end to be within the previous 18 months and do not accept drafts or projections.
Nationwide: sole traders and partnerships
Published criteriaFor sole traders and partners, Nationwide uses the lower of the most recent net profit figure or the average of the last two years. Its published evidence options include HMRC tax calculations with tax year overviews or an accountant's certificate.
Halifax: one full year can be considered
Published criteriaHalifax states that where the customer has been trading for less than 2 years but for at least one full year, the application can be considered. In those cases, accounts are its preferred evidence route.
The practical takeaway
A stronger self-employed mortgage case is not only about gathering documents. It is about matching your business structure and trading history to a lender that clearly recognises them in published criteria.
Case Shapes
What lenders are really trying to understand in a self-employed case
These are the distinctions that usually matter more than a headline statement like self-employed income.
Sole trader or partner
Expect the lender to focus on filed net profit or share of net profit rather than business turnover on its own.
Limited company director
Expect salary, dividends and the recency of the latest filed year end to matter more than broad company revenue headlines.
One full year of trading
Some lenders can consider this, but the range is narrower and the quality of the accounts becomes more important.
Freshly filed return
If the latest figures were only just submitted, the 72-hour HMRC printing delay can still slow a live application.
Preparation Plan
A stronger sequence for self-employed applicants
This order helps reduce avoidable underwriting delays, weak lender matches and last-minute document problems.
- 1
Pull the HMRC documents before you start comparing lenders
Start with the SA302s and tax year overviews you can evidence now, so the application is built on filed figures rather than on informal summaries or accountant emails.
- 2
Build in the HMRC printing delay
You cannot print the tax calculation until 72 hours after the return is sent. If the return has only just been filed, leave room for that delay before promising documents to a lender or broker.
- 3
Match the case to published criteria, not generic self-employed advice
Check how the lender treats your business structure before you apply. Sole trader profit, partnership income and director salary-plus-dividends do not all travel through underwriting in the same way.
- 4
Verify the adviser before you pay or share sensitive records
Check the firm, then the individual if needed, and agree the fee and service scope before you send accounts, tax records or company documents.
Trust and Safety
How to choose an adviser without adding avoidable risk
Checking the adviser matters just as much as checking the mortgage. Start with authorisation, then make the payment route clear before the case gets personal.
Use the FCA tools in the right order
- Use the FCA Firm Checker when you are buying a new mortgage service and want to confirm the firm is authorised for that activity.
- Use the Financial Services Register if you want the wider regulatory record or need to check an individual adviser rather than only the firm.
- Compare the contact details you were given with the FCA listing instead of relying on links in emails, messages or social profiles.
Agree the fee and service scope early
Before you share accounts or tax documents, ask how the adviser will be paid, whether any broker fee applies, and at what stage that cost becomes payable.

Frequently Asked Questions
What proof of income can I get from HMRC for a mortgage application?
You can get SA302 evidence for the last 4 tax years and a tax year overview for any year. Lenders often want both together when they review a self-employed case.
How quickly can I print my SA302 after filing a tax return?
You cannot print the tax calculation and tax year overview until 72 hours after you send the tax return, so that delay needs to be built into your preparation timing.
Do all lenders assess self-employed income in the same way?
No. Mainstream lenders publish different criteria. Nationwide uses lower-of-latest-year or two-year-average approaches in several self-employed cases, while Halifax can consider some borrowers with one full year of trading.
Can I get a mortgage with only one full year of trading?
Some lenders can consider it, but it is not universal. Halifax states that where a customer has been trading for less than 2 years but for at least one full year, the application can be considered, and accounts are its preferred evidence route in those cases.
How do I check whether a mortgage adviser or broker is genuine?
Use the FCA Firm Checker when you are buying a new mortgage service, then use the Financial Services Register if you need the wider regulatory record or want to check an individual adviser. Always compare the contact details you were given with the FCA listing.
