Advance Payments


Advance Payments "Payments on Account" for the next tax year

These are advance payments towards your next tax bill (including Class 4 National Insurance if you’re self-employed). 

You have to make 2 payments on account every year unless:

Your last Self Assessment tax bill was less than £1,000.

You’ve already paid more than 80% of all the tax you owe, for example through your tax code or because your bank has already deducted interest on your savings or you are in the CIS scheme. 

Each payment is half your previous year’s tax bill.

Payments are due by midnight on 31 January and 31 July.

If you still have tax to pay after you’ve made your payments on account, you must make a ‘balancing payment’ by midnight on 31 January next year.
