Key takeaways

• Access your SA302 form through your HMRC online account by waiting 72 hours after submitting your Self Assessment tax return, then navigate to 'Self Assessment' → 'More Self Assessment Details' → 'Get Your SA302 Tax Calculation'.

• Prepare SA302 forms for mortgage and loan applications by gathering documents from the last two to three years, as banks and lenders typically require this timeframe to verify your self-employed income.

• Recognise that SA302 forms provide comprehensive income verification including total earnings, tax allowances, and tax calculations, making them more valuable to lenders than basic tax overviews which only show summary information.

• Maintain accurate financial records throughout the year using accounting software to ensure your SA302 forms reflect complete and organised income data that banks and lenders will trust during their assessment process.

What is an SA302 form?

An SA302 form is HMRC's official tax calculation that summarises your annual income and tax position.

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

You receive your SA302 automatically after submitting your Self Assessment tax return. Banks and lenders accept this document as official proof of your income.

Who needs an SA302 form?

need SA302 forms to prove their income to banks and lenders.

You'll need an SA302 when:

• Applying for mortgages: Banks require proof of self-employed income, and over 50 lenders accept SA302s for income verification
• Securing business loans: Lenders need proof of your income
• Increasing credit limits: Banks and lenders check your ability to repay
• Renting properties: Landlords may request income verification

Unlike PAYE employees who receive payslips, self-employed people use SA302 forms as their official proof of income. This became even more important after self-certification mortgages stopped in 2014.

How to get my SA302 from HMRC

Getting your SA302 takes just a few minutes through your HMRC online account. You can access up to four years of tax calculations. You need to wait 72 hours after you send your tax return before you can print the documents.

Step-by-step process:

1. Log in: Access your HMRC online account using your UTR (Unique Tax Reference) number
2. Navigate: Go to 'Self Assessment' → 'More Self Assessment Details'
3. Download: Select 'Get Your SA302 Tax Calculation' to save or print

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

What does an SA302 look like?

Your SA302 contains three key sections that banks and lenders review:

Declared earnings: Your total annual income from:

• Self-employment profits
• Rental property income
• UK company dividends
• Bank interest and savings
• Pensions and state benefits

Taxable income: Earnings above the £12,570 standard Personal Allowance, which is the amount of income you don't have to pay tax on (excludes ISA savings and certain benefits).

Tax you owe: The exact amount you need to pay HMRC based on current tax rates

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 £12,570 Personal Allowance 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% = £3,086
• Her calculated Income Tax owed is £3,086

Once she has downloaded or printed her SA302 form, she can show it to the bank. The bank will use it to check how much she can afford to borrow. This is often around four to five times your income.

Is an SA302 the same as a tax overview?

No, SA302 and tax overview are different documents with different purposes.

SA302 form:

• Complete tax calculation with income breakdown
• Shows tax allowances and deductions
• Preferred by banks and lenders

Tax overview:

• Basic summary of reported income
• Shows outstanding amounts only
• Less detailed than SA302

Banks and lenders prefer SA302 forms because they give a full picture of your income, not just a summary.

FAQs on SA302 forms

Here are answers to some common questions about SA302 forms.

Is SA302 proof of income?

Yes, an SA302 form is widely accepted as official proof of your earnings for a tax year. Lenders and mortgage providers use it to verify the income you've declared to HMRC, which helps them assess your ability to make repayments.

How long does it take to get SA302 from HMRC?

After you file your Self Assessment tax return online, you need to wait 72 hours before you can download your SA302. If you file by post, it will take longer for HMRC to process your return and make the calculation available.

Do banks and lenders accept SA302 forms?

Yes, most UK banks and mortgage lenders accept SA302 forms as proof of income for the self-employed. They often ask for this alongside a Tax Year Overview to confirm your earnings and that your tax is up to date.

Can I get SA302 for multiple tax years?

You can access and print SA302 tax calculations for up to the last four tax years directly from your HMRC online account. This is useful as many lenders require two or three years of income history.
