Understand your Self Assessment tax bill
You’ll get a bill when you’ve filed your tax return. If you filed online you can view this:
- when you’ve finished filling in your return (but before you submit it) - in the section ‘View your calculation’
- in your final tax calculation - it can take up to 72 hours after you’ve submitted your return for this to be available in your account
HMRC will send your bill by post if you did a paper return.
You may need your tax calculation (known as a ‘SA302’), for example if you’re self-employed and applying for a mortgage.
This guide is also available in Welsh (Cymraeg).
Understanding your bill
Your bill includes the tax you owe for the last tax year. This is called a ‘balancing payment’ on your bill.
If this is more than £1,000, your bill will usually include an additional payment towards next year’s bill (known as a ‘payment on account’).
If you made payments on account last year
You’ll need to deduct any payments on account you made last year towards this year’s bill to work out what you owe.
Log in to your account and click ‘View statements’ to check the payments on account you made last year.
