If you are self-employed and applying for a mortgage, one of the first things a lender will ask for is your SA302. Understanding how to get SA302 for mortgage applications can save time and help avoid delays.
At Key Mortgage Advice, we regularly support clients who are part way through an application and need to provide income evidence quickly. Knowing what an SA302 is, how to download it and what lenders expect can make the process much smoother.
What Is An SA302 For A Mortgage?
An SA302 is a tax calculation document produced by HMRC after you submit your self assessment tax return. It shows your income for that tax year, along with the tax you owe.
Mortgage lenders use SA302s to confirm your income if you are self-employed. This includes sole traders, limited company directors and freelancers.
The SA302 gives lenders a clear view of what you have declared to HMRC. It is one of the main ways they assess affordability when you do not have payslips.
Why Lenders Ask For An SA302
Lenders need consistent and reliable proof of income before they approve a mortgage. For employed applicants, this comes from payslips and employer references. For self employed applicants, it comes from tax records.
SA302s are used alongside tax year overviews to confirm that the figures match what has been submitted and paid. Most lenders will ask for the last two years of SA302s, although some may request three years depending on your situation.
How Do I Get An SA302 For A Mortgage?
The quickest way to get your SA302 is through your HMRC online account.
If you already use the Government Gateway, you can download your documents straight away.
- Log in to your HMRC account using your Government Gateway details
- Go to your self assessment section
- Select the relevant tax year
- View your tax calculation
- Download the SA302 and save it as a PDF
You should also download your tax year overview for the same period, as lenders usually require both documents.
If you do not have access to your online account, you can request the documents from HMRC, although this may take longer.
Can An Accountant Provide An SA302?
Your accountant may be able to provide a tax calculation that looks similar to an SA302. Some lenders accept accountant produced documents, while others will only accept those from HMRC.
In most cases, lenders will still require the tax year overview from HMRC to match the figures.
To avoid delays, it is usually best to download both documents directly from your HMRC account.
How Many Years Of SA302 Are Needed For A Mortgage?
Most lenders ask for at least two years of SA302s and tax year overviews. This helps them assess whether your income is stable.
Some lenders may consider one year of accounts if other parts of your application are strong, such as a larger deposit or previous experience in the same line of work. This is not guaranteed and options may be more limited.
If your income varies from year to year, lenders may use an average or take a cautious approach depending on the trend.
How Long Does It Take To Get An SA302?
If your tax return has already been submitted and processed, you can usually download your SA302 instantly through your HMRC login.
If you need to request it from HMRC, it may take up to a couple of weeks.
Delays often happen when tax returns have not been submitted or when access to the online account has been lost. Preparing early can help avoid last minute issues.

What Supporting Documents Do You Need?
SA302s are only part of the application. Lenders will normally ask for additional documents to support your income.
This often includes tax year overviews, business accounts, bank statements and proof of identification. All documents need to match. If there are differences between your SA302 and your tax year overview, the lender may ask for clarification or delay the application.
What If Your SA302 Does Not Match Your Tax Overview?
A mismatch between documents is a common issue.
This can happen if payments have not been updated, returns have been amended or figures have been entered incorrectly. Lenders rely on these documents to confirm income, so any difference can slow down the process.
If this happens, it is important to speak to your accountant or check your HMRC records to resolve the issue before submitting your application.
Can You Get A Mortgage Without An SA302?
If you are fully self employed and complete a tax return, most lenders will expect SA302s as part of the application.
There are some exceptions, particularly for contractors who may be assessed on day rate income, but this depends on the lender and the structure of your work. In most cases, having your SA302s ready is essential for a smooth application.
Avoiding Delays In Your Mortgage Application
One of the most common reasons for delays is missing or incorrect paperwork.
Having your SA302s, tax year overviews and supporting documents ready before you apply can make a significant difference.
