How to Access Your SA302s and Tax Year Overviews (Without Losing Your Sanity)
If you’re self-employed, a company director, or have multiple income streams, there’s a strong chance you’ll be asked for SA302s and Tax Year Overviews as part of a UK mortgage application.
In theory, accessing these documents should be straightforward.
In reality, it’s one of the most common points where otherwise organised people lose time, patience, or momentum.
This guide explains how to get your SA302s and Tax Year Overviews, clearly and calmly — without unnecessary stress.
What are SA302s and Tax Year Overviews used for?
Lenders use these documents to verify income when standard payslips aren’t available.
- SA302 – shows the income you declared to HMRC for a specific tax year
- Tax Year Overview – confirms what HMRC has recorded as submitted and paid
Most mortgage lenders require both documents, for the same tax years, and they must match.
How to access your SA302s depends on how you file your tax return
This is where most confusion arises.
If you file your own Self Assessment online
You’ll need your HMRC Government Gateway login.
Steps:
- Log in to HMRC Self Assessment
- Select More details
- Choose Get your SA302
- Download the required tax years
- Return to Self Assessment and select Tax Year Overview
- Download the matching years
Save each document clearly labelled by tax year.
If your accountant files your tax return
You won’t be able to download SA302s yourself.
Instead, ask your accountant for:
- SA302s for the required years
- Matching Tax Year Overviews
- Or an Accountant’s Tax Calculation accepted by many lenders
This is routine for accountants — clarity on what’s needed avoids delays.
Common SA302 issues that delay mortgage applications
We regularly see applications slowed by:
- Downloading the wrong tax years
- Providing SA302s without Tax Year Overviews
- Outstanding tax showing on HMRC records
- Screenshots instead of official PDFs
These aren’t deal-breakers, but they’re easier to resolve before a mortgage application is submitted.
A quiet word of reassurance
For many people, this is the first time they’ve logged into HMRC systems in years — often while juggling a property purchase, work, and family life.
If you’re unsure which documents you’ll be asked for, or want to confirm everything is correct before a lender reviews it, that’s a sensible step to take early.
