SA302 Tax Calculations: What They Are and When You Need One
If you’re self-employed and applying for a mortgage or loan, the lenders will often ask for SA302 tax calculations. But what exactly is it, and how do you get one? Here’s everything you need to know.
What are SA302 Tax Calculations?
SA302 calculations are produced by HMRC. They show:
- Your total income for the year
- How much tax is due (or already paid)
- The breakdown of how your tax was calculated
And are based on the figures from your Self Assessment tax returns.
Why Do Lenders Ask for It?
When you apply for a mortgage or finance, lenders want proof of your income. An SA302 shows that:
- You’ve declared your income to HMRC
- Your figures match an official tax calculation
- You can realistically afford the repayments
Most lenders ask for at least two years’ worth of SA302s, sometimes three.
SA302 Tax Calculations vs Tax Year Overview (TYO)
Lenders usually don’t accept an SA302 alone. They’ll also want the Tax Year Overview to:
- Confirm HMRC has received the return
- Show that tax due has been paid (or is scheduled)
👉 In short, the SA302 shows the calculation, while the TYO confirms HMRC agrees with it.
How Do You Get an SA302?
You can get your SA302 by:
- Logging into your HMRC online account
- Going to “Self Assessment” → “View Your Tax Return”
- Selecting the tax year and downloading the SA302 PDF
If you use an accountant, they can provide the document directly from HMRC-approved software.
Common Mistakes
- Sending a tax return printout instead of an SA302
- Providing only one year when the lender asks for three
- Forgetting to include the matching TYO
These can all delay your application.

Getting the paperwork right can make the difference between a fast mortgage approval and weeks of delays. As your accountant, I can:
- Quickly provide the correct SA302 and TYO documents
- Make sure the figures match
- Save you time and stress when dealing with lenders
