How to Get Your Previous Tax Returns From HMRC
Whether you’re applying for a mortgage, correcting an error, or just keeping your records straight, HMRC keeps a copy of everything you’ve filed online — you just need to know where to look, and how far back you can actually go.
This guide covers how to get your previous UK tax returns from HMRC: viewing them in your online account, getting an SA302 for mortgage applications, requesting older records, and what to do if you need to correct a return you’ve already filed.
Key Takeaways
- You can view and print your last 4 years of SA302 tax calculations directly from your HMRC online account.
- You can only print documents 72 hours after you’ve submitted that year’s Self Assessment return.
- An SA302, paired with your Tax Year Overview, is the standard evidence UK lenders ask for when you apply for a mortgage as self-employed.
- Returns older than 4 years need a written request to HMRC rather than online access.
- You can amend a filed return up to 31 January, 2 years after that return’s original due date — after that, you need to submit a written overpayment relief claim instead.
- HMRC generally expects you to keep your own records for at least 5 years after the Self Assessment deadline (6 years for limited companies).

Getting Your Return From Your HMRC Online Account
The fastest way to get a previous UK tax return is through your HMRC online account — log in with your Government Gateway details, go to Self Assessment, then select the relevant tax year to view or print.
- Sign in at gov.uk using your Government Gateway user ID and password.
- Go to “Self Assessment,” then “More details about your Self Assessment returns and payments.”
- Select the tax year you need, then view or print your tax calculation and return.
- If your accountant filed on your behalf, they can usually retrieve a copy faster from their own agent account or records.
SA302: What It Is and Why Lenders Ask for It
An SA302 is HMRC’s official tax calculation for a given tax year, showing your declared income, allowances and tax due — self-employed applicants use it, alongside a Tax Year Overview, as proof of income for mortgages and loans in place of a payslip.
- You can access SA302 tax calculations online for the last 4 tax years.
- Most lenders ask for 2–3 years’ worth, though this varies by lender and application type.
- The Tax Year Overview is a separate document confirming the tax actually charged and paid — lenders typically want both together, since the figures corroborate each other.
- If you use commercial filing software rather than HMRC’s own portal, you can usually still print an SA302 the same way through your account.
Getting Returns Older Than 4 Years
For tax returns older than the 4-year online access window, you’ll need to request a copy directly from HMRC in writing, or rely on your own or your accountant’s saved records if you have them.
- Call or write to HMRC directly to request older SA302s or return copies.
- If you used an accountant, check with them first — they may hold their own copies going back further than HMRC’s online window.
- Written requests generally take longer to process than the instant online access available for recent years.
Correcting or Amending a Previous Return
You can amend a Self Assessment return up to 31 January, 2 years after that return’s original filing deadline — beyond that window, corrections require a written overpayment relief claim to HMRC instead of a simple online amendment.
- Online amendments within the window are usually the fastest route to correct an error.
- Outside the window, you’ll need to follow HMRC’s overpayment relief claim process, which takes longer and requires a written submission.
- Keep your original return and supporting records to hand — accurately correcting a return is far harder without them.
Online Access vs Written Request: Compared
| Online (Last 4 Years) | Written Request (Older) | |
|---|---|---|
| Speed | Instant, once 72 hours have passed since filing | Slower — HMRC processes by post |
| What you get | SA302 tax calculation + Tax Year Overview | Copy of the original return or calculation |
| Access method | Government Gateway online account | Letter or phone request to HMRC |
| Best for | Mortgage applications, recent record checks | Historic disputes, long-past record requests |
Common Challenges
- Trying to print documents before the 72-hour window has passed
- Not realising the 4-year online limit before needing an older return urgently
- Confusing the SA302 with the Tax Year Overview when a lender asks for both
- Missing the amendment window and needing a more involved overpayment relief claim instead
- Losing access to an accountant’s records after switching providers, without requesting a handover first
Illustrative Examples
Illustrative Example — Mortgage Application: A self-employed applicant logs into their HMRC account, prints SA302s and Tax Year Overviews for the last 2 years, and submits both together as their lender requires.
Illustrative Example — Correcting an Error: A sole trader spots a missed expense from 18 months ago, still within the amendment window, and corrects it online rather than needing a written claim.
Illustrative Example — Older Record Request: A landlord needs a tax return from 6 years ago for a legal matter and writes to HMRC directly, since it falls outside the 4-year online access window.
Common Mistakes to Avoid
| Mistake | Why It Happens | Consequence | How to Avoid It |
|---|---|---|---|
| Trying to print immediately after filing | Not knowing about the 72-hour delay | Frustration, wasted time close to a lender deadline | Allow at least 72 hours after filing before requesting documents |
| Only downloading the SA302, not the Tax Year Overview | Assuming one document is enough | Lender rejects an incomplete submission | Download both documents together for the relevant years |
| Leaving old record requests too late | Not anticipating a future need for older records | Delays during a time-sensitive application | Keep your own saved copies each year, beyond HMRC’s 4-year window |
| Missing the amendment deadline | Not tracking the 2-year window from the filing deadline | A slower, more involved overpayment relief claim required | Correct errors as soon as you spot them, well within the window |
| Losing accountant-held records after switching | Not requesting a handover when changing accountants | Gaps in your own record history | Ask your outgoing accountant for copies of all filed records before switching |
Editor’s Insights
- The 4-year SA302 window catches people out most often around mortgage applications — check your access early, not the week you need it.
- If you use an accountant, they often retrieve documents faster than the standalone HMRC portal process, especially for straightforward Self Assessment filers.
- Keeping your own digital archive of returns and calculations each year removes reliance on HMRC’s access window entirely.
- The overpayment relief claim process for older corrections is considerably slower than an in-window amendment — timing genuinely matters here.
- A Tax Year Overview and an SA302 look similar but serve different purposes — always check exactly what a lender or third party is asking for.
Which Route Do You Need? Decision Framework
- Do you need a return from the last 4 tax years? Use your HMRC online account — it’s instant once 72 hours have passed since filing.
- Is it older than 4 years? You’ll need to request it in writing from HMRC directly.
- Do you need to correct an error? Check whether you’re still within the 2-year amendment window from the original deadline.
- Did an accountant file for you? Ask them first — they may retrieve records faster than starting from HMRC’s own portal.
Checklist: Getting Your Previous Tax Return
- ☐ Confirm which tax year you need and whether it falls within the 4-year online window
- ☐ Log into your HMRC online account with your Government Gateway details
- ☐ Download both the SA302 and Tax Year Overview if applying for a mortgage
- ☐ Contact HMRC in writing for anything older than 4 years
- ☐ Check the amendment deadline before attempting to correct an old return
- ☐ Save your own copies each year going forward, rather than relying solely on HMRC’s window
Frequently Asked Questions
How do I get a copy of my previous tax return in the UK?
Log into your HMRC online account and view or print it under Self Assessment — this works for the last 4 tax years; older returns need a written request to HMRC.
What is an SA302 and how far back can I get one?
An SA302 is HMRC’s official tax calculation for a given year, available online for the last 4 years — commonly used as proof of income for mortgage applications.
How long does HMRC keep my tax return records?
Online access covers the last 4 years directly; you’re separately required to keep your own records for at least 5 years after the Self Assessment deadline (6 years for limited companies).
Can I amend a tax return from 3 years ago?
Only within the amendment window, which runs to 31 January, 2 years after that return’s original filing deadline. Beyond that, you’ll need to submit a written overpayment relief claim.
What’s the difference between an SA302 and a Tax Year Overview?
The SA302 shows a full breakdown of your income, allowances and tax calculation; the Tax Year Overview confirms the tax actually charged and paid — lenders typically want both together.
Can my accountant get my previous tax returns for me?
Yes — if they filed on your behalf, they can often retrieve copies from their own records or agent account faster than the standalone HMRC portal process.
