When do I need to pay my tax?

The balance of personal tax owed to HMRC for the year ended 5th April (e.g. 2022) is due by the following 31st January (e.g. 2023). The balance payable will be your tax liability, minus any payments on account already paid. However, you may also need to pay two payments on account towards the next tax year. If so, these are due by by 31st January (e.g. 2023) and 31st July (e.g. 2023).
