Key takeaways

• Obtain your SA302 form by logging into your HMRC online account at least 72 hours after submitting your Self Assessment return, as lenders widely accept it as official proof of self-employed income for mortgages, loans, and rental applications.
• Request both your SA302 and your tax year overview when applying for a mortgage or loan, as many UK lenders ask for both documents together, typically covering the last two to three years.
• Recognise the difference between an SA302 and a tax year overview: the SA302 gives a full breakdown of your income, allowances, and tax owed, while the tax year overview only shows a basic summary, making the SA302 the preferred document for lenders.
• Keep accurate, organised income records throughout the year so your Self Assessment return is correct, as your SA302 is generated directly from the figures you declare to HMRC.

What is an SA302 form?

An SA302 form is HMRC's official tax calculation that summarises your annual income and tax position. Self-employed individuals use it to get evidence of your earnings for the last four years when applying for mortgages, loans, or rental agreements.

The form includes:

• Total income: all earnings from self-employment, rental properties, and other sources
• Tax allowances: personal allowance and other deductions
• Tax calculations: amount owed or already paid to HMRC

After HMRC processes an online Self Assessment tax return, you can usually view and print your tax calculation from your HMRC online account. Many UK lenders accept this document as proof of your income, though requirements vary by lender.

Who needs an SA302 form?

Banks and lenders often ask self-employed individuals and business owners for SA302 forms to prove their income.

You might need an SA302 when:

• Mortgage applications: banks require proof of self-employed income, and many lenders accept SA302s to verify your earnings
• Business loan applications: lenders assess your income before approving funding
• Credit limit increases: banks check your ability to repay higher amounts
• Rental applications: landlords may ask to verify your income before signing a tenancy

Unlike PAYE employees who receive payslips, lenders commonly ask self-employed applicants for SA302s and tax year overviews. This became even more important after regulators effectively prohibited self-certification mortgages in 2014.

How to get my SA302 from HMRC

Getting your SA302 takes just a few minutes through your HMRC online account or commercial accounting software. You need to wait 72 hours after submitting your tax return before you can access the document, as HMRC systems allow you to print your documents only after this period. Once available, you can download tax calculations for up to four years.

What you need: your Unique Tax Reference (UTR) number and access to your HMRC online account.

Using HMRC online services

Follow these steps to download your SA302 from the HMRC portal:

1. Log in to your HMRC online account using your Government Gateway user ID and password
2. Navigate to 'Self Assessment' then 'More Self Assessment Details'
3. Select 'Get Your SA302 Tax Calculation' to save or print your document

Using commercial accounting software

If you file your Self Assessment through accounting software rather than HMRC's online services, you can still access your SA302. Your options are:

• Access HMRC directly: Log in to your HMRC online account to download the SA302, even if you filed through software
• Contact your software provider: Some providers offer guidance on accessing tax documents
• Request from HMRC: Call or write to HMRC if you need help accessing your online account

HMRC always generates the SA302, regardless of how you submit your tax return.

Contact HMRC if you need help

If you need help accessing your SA302 online, contact HMRC directly. You can:

• Call the Self Assessment helpline: 0300 200 3310 (Monday to Friday, 8 am to 6 pm)
• Request by post: Write to HMRC and ask them to send your SA302 and tax year overview

Allow extra time if you need documents posted, as this can take several weeks.

What does an SA302 look like?

An HMRC tax calculation shows how HMRC calculated your income and tax from your Self Assessment return. Lenders may review income, taxable income, and tax figures, but exact review criteria vary.

Declared earnings: your total annual income from:

• self-employment profits
• rental property income
• UK company dividends
• bank interest and savings
• some pension or benefit income where applicable

Taxable income: earnings above the £12,570 standard personal allowance. This is the amount of income you don't have to pay tax on, excluding Individual Savings Account (ISA) savings and certain benefits.

Tax calculation: shows how HMRC calculated your income tax and related liabilities for that return. The amount still payable may differ after accounting for payments made or penalties.

An SA302 example

Meet Sunita. She runs her own hairdressing business and owns a flat that she rents out. She wants to double the size of her hair salon and needs a loan from a bank.

After completing her Self Assessment Tax Return for the year, she can access an SA302 form which includes the following information:

• Her declared earnings total £28,000 (£21,000 from her salon and £7,000 from her flat)
• She gets the standard £12,570 personal allowance, representing the amount of income she doesn't have to pay tax on, which leaves a taxable income of £15,430 (£28,000 - £12,570 = £15,430)
• This income tax is charged at the basic rate of 20%, which covers taxable income from £12,571 to £50,270, equalling £3,086
• Her calculated income tax is £3,086, though her total Self Assessment bill may also include National Insurance contributions.

Once she has downloaded or printed her SA302 form, she can show it to the bank. Lenders assess affordability using income, outgoings, credit commitments, and their own underwriting criteria.

Is an SA302 the same as a tax overview?

No. An SA302 is a detailed tax calculation showing your income breakdown, allowances, and tax owed. A tax year overview is a shorter summary covering the period from 6 April to 5 April that only shows your total income and any outstanding amounts.

The SA302 form includes the following details:

• Provides complete tax calculation with income breakdown
• Shows tax allowances and deductions
• Is preferred by banks and lenders to verify income

The tax year overview includes:

• Provides basic summary of reported income
• Shows outstanding amounts only
• Offers less detail than SA302

Banks and lenders prefer SA302 forms because they give a full picture of your income, including detailed breakdowns. Many lenders request both documents together.
