What Are an SA302 and a Tax Year Overview? (Explained for Mortgages)

If you’re self-employed and applying for a mortgage, lenders will usually ask for two key documents to verify your income:

  • SA302 (Tax Calculation)
  • Tax Year Overview

Although they sound similar, they serve different purposes.

What is an SA302?

An SA302, also known as a Tax Calculation, shows a breakdown of your income for a specific tax year. It includes:

For mortgage purposes, lenders use the SA302 to verify your declared income. This helps them assess how much you can borrow.

What is a Tax Year Overview?

A Tax Year Overview confirms that:

  • The tax return for that year has been submitted
  • The figures match HMRC’s records
  • Any tax owed has been paid (or is outstanding)

Lenders ask for this alongside your SA302 to ensure the information is accurate and officially recorded by HMRC.

Why Do Mortgage Lenders Require Both?

Mortgage lenders want to:

  • Verify your income is legitimate
  • Check consistency across multiple years
  • Ensure there are no unpaid tax issues
  • Confirm the figures submitted match HMRC records

In short, these documents help prove your income is stable, reliable and properly declared, this is essential for a self-employed mortgage application.

How Many Years of SA302s Do Lenders Typically Ask For?

Most lenders request:

  • The last 2 years of SA302s and Tax Year Overviews
  • Some may ask for 3 years
  • A small number of specialist lenders may consider just 1 year

The more consistent your income appears, the stronger your application tends to be.

If your income has increased significantly in the latest year, some lenders may use the most recent figure, but others may average the last two years instead. Because criteria varies, it’s important to check which lenders are most suitable before submitting documents.

Alternative Ways to Get These Documents – Use an Accountant

If you’re struggling to download your SA302 or Tax Year Overview directly from HMRC, if you use an accountant, they can usually:

  • Generate an SA302 directly from HMRC-recognised software
  • Provide an accountant’s tax calculation summary

Some lenders accept accountant-generated documents, while others prefer them downloaded directly from HMRC. It’s always worth checking first.

Common Errors & Red Flags to Avoid

Submitting the wrong version of these documents can delay your mortgage application. Here are the most common mistakes we see:

Mismatch Between SA302 & Tax Year Overview

The income figure on your SA302 must match the income shown on your Tax Year Overview for that same tax year. If they don’t match, lenders may:

  • Pause the application
  • Request clarification
  • Decline the case until resolved

Always double-check both documents align before sending them.

Printing or Downloading Incorrectly

Common issues include:

  • Missing pages
  • Cropped PDFs
  • Screenshots instead of full downloads
  • Poor quality scans

Lenders need full, clear documents, not partial screenshots.

Missing HMRC Branding or Reference

Some lenders require:

  • The HMRC logo
  • Unique tax reference (UTR)
  • Submission confirmation details

If these are missing, documents may be rejected.
