How to Get Your SA302 Tax Calculation Form and Overview Online

How to Get Your SA302 Tax Calculation Form and Overview Online.

Your SA302 is an official HMRC document that confirms your tax and income which you can download online.


You can get your SA302 form online or you can order it by phone. It is an official HMRC document confirming your tax and income.

So for that reason, you need to either log in to your HMRC online account or call them to get it.

When you apply for a loan or mortgage you need to prove your earnings.  And the more earnings you can show the more eligible and amount you can borrow.

An SA302 Tax Calculation Form acts as evidence from HMRC of your income for lenders.  So it backs up what you have put in your application form.

Depending on what you are applying for you may need to provide more than one SA302 Tax Calculation Form.  This is because one form only covers one self assessment tax return.

Your mortgage advisor or lender will advise you of what is needed as part of your application.

What is an SA302 Form

An SA302 is now commonly known as a Tax Calculation Form, although many people still refer to it by its old name. 

It is a summary form showing your total income and tax due for each tax year.

A tax year runs from 6 April to 5 April each year. And the information is taken from your self-assessment tax return.

The SA302 Tax Calculation acts as proof of income and is usually requested as part of mortgage applications.

In the past an SA302 or HMRC Tax Calculation & Tax Overview used to be issued by letter.  Over recent years HMRC have made this available online and luckily lenders have become happy to accept them. Speeding up the application process.

What is an SA302 Form

An SA302 form is an HMRC document that is now becoming known as a Tax Calculation Form.

It shows:

  • All your different forms of income declared on your self-assessment tax return form like rental income, self-employment income and dividends;
  • How tax on all your income was worked out.

One SA302 form covers one tax year.

A UK Tax year runs from 6 April to 5 April. So your SA302 form for 2018/2019 will summarise all your income and tax calculations for 6 April 2018 to 5 April 2019.

Why Do You Need to Get Your SA302 Form

Your SA302 form is commonly requested as part of lending or mortgage applications:

  • As evidence of your earnings declared in the application;
  • Verify affordability if you are self employed and run your own business;

Commonly you may be asked to get your Tax Overview as well as your Tax Calculation.

What Does an SA302 Look Like?

An SA302 is made up of two parts – your tax calculation and tax overview.


What is a Tax Overview Form?

A tax overview form is a summary, by tax year, of:

  • Total tax payable;
  • How much tax has been paid;
  • Unpaid tax, if any.

Here is what a Tax Overview Form looks like:


Example SA302 Tax Calculation and Tax Overview

Depending on where you download your SA302 Tax Calculation and Tax Overview, it may look slightly different.  Here are the three types of forms you should expect to see:

  1. Example SA302 Letter from HMRC HERE
  2. Example SA302 Online HMRC Tax Calculation HERE
  3. Example SA302 Online HMRC Tax Overview HERE

Each tax calculation and overview covers one tax year. So you may need to download more than one document.

How Can I Get My SA302 Form Online

You can get your SA302 from HMRC by going online, assuming you are up to date with filing your self-assessment tax return forms.

How to File Your Tax Return Online

Check with your lender or broker exactly what you need. But the two documents you are most likely to need are:

  • Tax Calculation – which is a summary of your total earnings and tax from your submitted tax return;
  • Tax Overview – which confirms that you have fully paid up your tax.

Each tax calculation and overview is for one tax year. So if your application requires evidence going back 3 years then you need 3 tax calculations and 3 tax overviews.
