If you’re self-employed, a sole trader, or run a small business in the UK, chances are you’ve heard of the SA302 form. Whether you’re applying for a mortgage, a loan, or simply need to prove your earnings, this document is one of the most requested forms by financial institutions.
In this guide, we’ll explain everything you need to know about the SA302 form in 2025 – from what it is, how to obtain it, to who needs it and why.
Summary
“SA302 is a crucial HMRC document that certifies your declared income, often required for mortgages and loan applications.”
What Is an SA302?
The SA302 is an official tax calculation document provided by HM Revenue & Customs (HMRC). It summarises your total income and tax liabilities based on your Self Assessment tax return for a specific tax year. Essentially, it acts as HMRC’s formal validation of your income details for that year.
This document is most commonly required by mortgage lenders, banks, or loan providers to verify your self-employed income. It includes information such as:
- Total income earned
- Taxable income
- Income tax paid
- National Insurance contributions
It’s typically used alongside a Tax Year Overview to give lenders full confidence in the accuracy of your earnings.
Summary
“SA302 is HMRC’s summary of your Self Assessment, detailing income, tax paid, and is often needed to prove financial reliability.”
When Is the SA302 Required?
The SA302 is primarily needed when you must prove your income. This usually applies if you are:
- Applying for a mortgage
- Applying for a personal or business loan
- Looking to rent a property
- Proving income to a visa authority
- Submitting financial information to a government agency or institution
In 2025, with the growing number of self-employed workers in the UK, lenders have tightened their documentation requirements.
SA302 forms serve as a reliable proof of earnings for self-employed individuals, contractors, freelancers, and directors with non-PAYE income.
Summary
“SA302s are essential for mortgage, loan, or visa applications, especially if you’re self-employed or not paid via PAYE.”

What Information Does the SA302 Contain?
An SA302 provides a comprehensive breakdown of your tax affairs for a particular tax year. The document typically includes:
- Your name and UTR (Unique Taxpayer Reference)
- The tax year covered
- Total income from all sources (e.g., self-employment, dividends, rental income)
- Total taxable income
- Personal allowance used
- Income tax due and paid
- Class 2 and Class 4 National Insurance contributions (if applicable)
Lenders and brokers use this data to assess whether your reported income is sufficient and stable enough to justify lending.
Summary
“The SA302 outlines your income sources, tax paid, and NI contributions – all of which lenders use to assess loan eligibility.”
How to Get an SA302 in 2025?
1. If You Submitted Your Tax Return Online via HMRC:
You can download your SA302 from your HMRC online account:
- Go to HMRC Online Services
- Log in with your Government Gateway ID
- Navigate to ‘Self Assessment’
- Click ‘More Self Assessment details’
- Select ‘Tax Year’ and then click to view and print your SA302
You can also view your Tax Year Overview from the same section to verify the SA302.
Summary
“You can easily download your SA302 through HMRC’s online portal if you submitted your tax return online.”
2. If You Used Commercial Accounting Software:
Many accounting software solutions such as Xero, QuickBooks, or GoSimpleTax allow users to submit Self Assessment returns directly to HMRC. These platforms usually generate a downloadable SA302 equivalent after submission.
If you’re using such software, follow the provider’s instructions to retrieve your SA302 and Tax Year Overview. Some lenders accept printed versions from these software platforms, but you should confirm with your lender first.
Summary
“If you file via accounting software, you can often download your SA302 directly from the platform – just ensure your lender accepts it.”
3. If You Filed a Paper Tax Return:
If you submitted your Self Assessment by paper, HMRC will send the SA302 automatically by post after processing your return. This may take a few weeks. If you misplace it or never received it, you can request a replacement by contacting HMRC directly.
You’ll need to provide:
- Your National Insurance number
- Unique Taxpayer Reference (UTR)
HMRC Contact Info:
📞 0300 200 3310
🌐 Contact HMRC
Summary
“Paper filers will get their SA302 by post, but can request a new one from HMRC if lost – with UTR and NI number handy.”
SA302 vs Tax Year Overview – What’s the Difference?
Though often submitted together, the SA302 and Tax Year Overview serve different purposes:
- SA302: Shows how your tax was calculated from the figures you submitted.
- Tax Year Overview: Confirms the tax owed and paid, verifying that your SA302 is accurate and complete.
Most mortgage lenders in 2025 will request both documents to process your application.
Lenders that accept printed SA302s:
Refer to HMRC’s official list of mortgage providers accepting SA302s.
Summary
“While the SA302 shows income and tax calculations, the Tax Year Overview validates those numbers – both are often required by lenders.”
Do All Lenders Accept Printed SA302s?
Not always. While many major UK lenders now accept digitally printed SA302s, some still insist on originals sent directly from HMRC. Always check lender requirements before submitting your documents.
For example:
- NatWest: Requires 2 years of SA302s and Tax Year Overviews
- Barclays: Accepts printed copies from HMRC or approved software
- Halifax: Accepts online printouts with matching Tax Year Overview
Summary
“Some lenders accept printed SA302s, others want originals – always confirm with the lender to avoid delays.”
What if I Can’t Access My SA302?
If you’re unable to obtain your SA302 online or via your software, follow these steps:
- Call HMRC’s Self Assessment helpline: 0300 200 3310
- Provide your:
- Full name
- National Insurance number
- UTR
- Address
- Full name
- Request your SA302 and Tax Year Overview for specific tax years
Alternatively, speak to your accountant if they filed your returns. They may be able to generate the documents through their portal or software.
Summary
“If you can’t get your SA302, call HMRC or contact your accountant – they can help you retrieve the required documents.”
How Long Is an SA302 Valid?
An SA302 doesn’t technically expire, but lenders usually require the last 2 to 3 years’ worth of documents. For most applications, SA302s from the 2022/23, 2023/24, and 2024/25 tax years will be requested in 2025.
It’s advisable to always keep digital and printed copies safely stored for at least 6 years for accounting and legal purposes.
Summary
“SA302s don’t expire, but lenders prefer the latest 2–3 years’ worth – keep yours safe and updated.”
Can You Get an SA302 for Previous Tax Years?
Yes. HMRC allows you to download SA302 forms for up to the last 4 tax years, assuming you submitted your Self Assessment online. You can view and print these by logging into your HMRC online account.
If older than 4 years, you may need to request them by contacting HMRC directly or speak to your accountant.
Summary
“SA302s for the last four years are available online; older ones may require HMRC assistance.”
Final Thoughts: Why the SA302 Still Matters in 2025
Despite the shift towards digital tax reporting under Making Tax Digital (MTD), the SA302 remains a critical piece of documentation for anyone outside the traditional PAYE system. Whether you’re securing a mortgage, applying for credit, or proving income for legal purposes, it is often your only reliable proof of declared earnings.
Summary
“Even in a digital-first era, the SA302 is indispensable proof of income for the self-employed.”
