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. SA302s and Tax Year Overviews are downloaded from your HMRC online account if you file your own Self Assessment, or requested from your accountant if they file on your behalf — most lenders need both documents, covering the same two to three tax years, with the figures on each matching.
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 both documents, clearly and calmly, without unnecessary stress.
What is an SA302?
An SA302 is HMRC’s summary of the income you declared on your Self Assessment tax return for a specific tax year. Lenders use it to verify income when standard payslips aren’t available — most commonly for self-employed applicants, sole traders, contractors, and company directors who pay themselves via dividends.
What is a Tax Year Overview?
A Tax Year Overview is HMRC’s confirmation of what you owed and paid for a given tax year, based on the return HMRC has on record. Lenders use it alongside the SA302 to cross-check that the declared income has actually been submitted and accepted by HMRC — not just self-reported.
Do lenders need both documents?
Yes. Most UK mortgage lenders require an SA302 and a matching Tax Year Overview for the same tax year, usually for the two or three most recent years. The figures on both documents need to correspond — a mismatch is one of the most common causes of delay.
How to get your SA302 if you file your own tax return
If you complete your own Self Assessment online, you can download both documents directly from your HMRC account:
- 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 so they’re easy to hand to your broker or lender.
How to get your SA302 if your accountant files for you
If an accountant submits your Self Assessment, you won’t be able to download the SA302 yourself — HMRC issues it to whoever files the return. Instead, ask your accountant for:
- SA302s for the required years
- Matching Tax Year Overviews
- Or an Accountant’s Tax Calculation, which many lenders accept as an alternative to the SA302
This is a routine request for accountants. Being specific about which tax years and which lender’s requirements avoids back-and-forth delays.
What commonly delays a mortgage application at this stage?
- Downloading the wrong tax years
- Providing SA302s without matching Tax Year Overviews
- Outstanding tax showing on HMRC’s records
- Submitting screenshots instead of official PDFs
None of these are deal-breakers, but they’re far easier to resolve before an application is submitted than after.
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. Specialist self-employed mortgage advice often makes the difference between an application being viable and not.
Frequently Asked Questions
What is an SA302 used for in a mortgage application?
Lenders use an SA302 to verify self-employed or director income when payslips aren’t available, checking it against your declared tax return figures.
Can I get an SA302 if my accountant files my tax return?
No, not directly. HMRC issues the SA302 to whoever submits the Self Assessment. You’ll need to request it from your accountant, along with a matching Tax Year Overview.
How many years of SA302s do lenders ask for?
Most lenders ask for two to three years’ worth, though this varies by lender and by how long you’ve been self-employed.
What’s the difference between an SA302 and a Tax Year Overview?
The SA302 shows the income you declared to HMRC. The Tax Year Overview confirms what HMRC has recorded as submitted and paid. Lenders need both because together they confirm the figures are genuine and accepted by HMRC.
Will a screenshot of my SA302 be accepted by a lender?
No. Lenders require the official PDF downloaded from HMRC (or issued by your accountant), not a screenshot.
