The deadlines for paying your tax bill are usually:
- 31 January - for any tax you owe for the previous tax year (known as a balancing payment) and your first payment on account
- 31 July for your second payment on account
Make sure you pay HM Revenue and Customs (HMRC) by the deadline. You’ll be charged interest and may have to pay a penalty if your payment is late.
The time you need to allow depends on how you pay.
