What Is an SA302 and How Do You Get One?

An SA302 is an official tax calculation produced by HM Revenue & Customs (HMRC). It summarises your income and tax position for a specific tax year and is generated once a Self Assessment tax return has been submitted.


SA302s are often required by mortgage lenders and other financial institutions as proof of income for self-employed individuals, company directors, and those with multiple income sources.


What Information Does an SA302 Show?


An SA302 provides a detailed breakdown of your income and tax calculation for the relevant tax year. This includes taxable income, allowances used, and the final tax liability. It shows HMRC’s calculation rather than simply what was submitted, which is why it is treated as reliable evidence by lenders.


A Tax Year Overview can be required to complete the SA302. The Tax Year Overview confirms whether the tax shown on the SA302 has been paid and must match the figures on the tax calculation.


Why Might You Need an SA302?


SA302s are typically required when applying for a mortgage or loan, particularly if you do not receive PAYE payslips. Lenders use them to assess income consistency and affordability, often requesting SA302s for the last two to three tax years.


Because lender requirements vary, it is always advisable to check exactly how many years are needed.

How to Obtain an SA302


If your tax return was filed online using your government gateway then SA302s can usually be downloaded directly from your HMRC online account. After signing in, navigate to the Self Assessment section, select the relevant tax year, and view or print your tax calculation.


If you submitted a paper tax return or no longer have access to your online account, HMRC can provide an SA302 by post, although this may take longer.


Alternatively, if your tax return was submitted using accounting software or through an accountant, the SA302 is unlikely to appear in your government gateway. Instead you should as your accountant who will be able to produce them from their system. Many lenders accept these versions provided they match the HMRC Tax Year Overview.


Summary


An SA302 is an essential document for many self-employed individuals and directors, providing official confirmation of income and tax calculations. When paired with a Tax Year Overview, it is widely accepted by lenders as proof of earnings. Ensuring these documents are accurate, up to date, and readily available can help avoid delays when applying for finance.
