# How to check your SA302

An SA302 is your official tax calculation document from HMRC. It shows how much tax and National Insurance you owe (or are due as a refund) based on your Self Assessment tax return for a specific tax year.

SA302 documents are commonly requested by mortgage lenders, loan providers, and landlords as proof of your income and tax affairs.

## What Information Is on an SA302?

Your SA302 tax calculation shows:

- All sources of income (employment, self-employment, benefits, etc.)
- Your personal allowance and any other allowances
- Taxable income after deductions
- Income tax and National Insurance contributions calculated
- Any tax already paid
- The final amount you owe or are due as a refund

## How to Access Your SA302

You can view and download your SA302 documents from your HMRC Personal Tax Account. Follow these steps:

### Step 1: Log In to Your Personal Tax Account

Go to [https://www.tax.service.gov.uk](https://www.tax.service.gov.uk) and sign in using your Government Gateway user ID and password.

If you don't have a Government Gateway account, you'll need to create one. You'll need your National Insurance number and information from a recent payslip, P60, passport, or credit reference file.

### Step 2: Select Self Assessment

Once logged in, look for the **Self Assessment** section on your account home page and select it.

### Step 3: Get Your SA302 Tax Calculation

Scroll down the Self Assessment page and look for the option **"Get your SA302 tax calculation"** or **"View your tax year overview"**.

### Step 4: Select the Tax Year

Choose which tax year you need the SA302 for. You can access calculations for any tax year where you've submitted a Self Assessment return.

### Step 5: View and Download

Your SA302 tax calculation will be displayed on screen. You can:

- **Print** the document directly
- **Save as PDF** using your browser's print function (select "Save as PDF" as the destination)
- **View on screen** for reference

## Understanding Your SA302

In the example above, the individual has three main income sources:

- **Employment:** £10,000
- **State benefits:** £1,000
- **Self-employment profit:** £5,000
- **Total income:** £16,000

After deducting the personal allowance (£11,850 in this example), the taxable income is £4,150. The SA302 then shows the income tax and National Insurance due on this amount.

**Note:** The personal allowance changes each tax year. For 2024/25, the personal allowance is £12,570 (for most people).

## Do You Need a Tax Year Overview Too?

Some mortgage lenders and financial institutions request both:

- **SA302:** Your tax calculation
- **Tax Year Overview:** A summary of your account showing payments made and liabilities

You can download your Tax Year Overview from the same area of your Personal Tax Account. Look for **"View your tax year overview"** or similar wording.

## When Do You Need Your SA302?

You'll commonly need your SA302 for:

- **Mortgage applications** - Lenders use it to verify your self-employed income
- **Rental applications** - Landlords may request it as proof of income
- **Loan applications** - Banks and finance companies verify your earnings
- **Visa applications** - Some visa categories require proof of UK income
- **Benefits applications** - Certain benefits require income verification
- **Your own records** - Good to keep for future reference

## How Many Years Do Lenders Usually Need?

Most mortgage lenders request SA302 documents for the most recent **2-3 tax years**. This helps them assess your income consistency.

Make sure you have submitted your tax returns for all the years they're requesting before applying for a mortgage.

## Troubleshooting

### I Can't See My SA302

If you can't find your SA302, it could be because:

- **You haven't submitted your tax return yet** - The SA302 is only generated after you submit your return
- **HMRC is still processing your return** - It can take a few days after submission for the SA302 to appear
- **You're logged into the wrong account** - Make sure you're using the correct Government Gateway ID
- **Technical issues** - Try logging out and back in, or use a different browser

### The Figures Look Wrong

If your SA302 shows figures that don't match what you expected:

- Check you're viewing the correct tax year
- Review your submitted tax return to see what was declared
- If there's an error, you may need to [amend your tax return](https://tax.malgrabooks.co.uk/knowledge-base/amending-your-tax-return)
- Contact HMRC if you believe there's a system error

### I Need SA302s for Years I Filed on Paper

If you filed paper tax returns in previous years, your SA302 calculations may not be available online. You'll need to:

- Call HMRC's Self Assessment helpline on 0300 200 3310
- Request copies of your SA302s for specific tax years
- Allow up to 15 working days for postal delivery

## Important Notes

- Your SA302 is an official HMRC document - don't alter or falsify it
- Keep copies of your SA302s for your records
- If you're self-employed, lenders typically want to see consistent or growing income
- Make sure your tax returns are submitted on time to avoid delays in accessing SA302s
- Some lenders may request additional documentation beyond the SA302
