If your self assessment tax liability for a tax year is over £1,000, and less than 80% of your tax is collected at source (e.g. PAYE), you will be required to pay two payments on account towards the following tax year. Each payment on account is calculated at 50% of your tax liability. The first payment is due by 31st January – the same date the tax return and balancing payment are due. The second payment on account is due by 31st July.

If you think your tax liability will be less in the following tax year, you can apply to reduce your payments on account. However, interest and potentially penalties could be payable if you reduce the payments on account too much.

The easiest way to pay your personal tax is by using online banking to make a payment to HMRC. Use sort code: 08-32-10, account number: 12001039, account name: HMRC Cumbernauld. You’ll need to add a payment reference so that HMRC allocate the payment against your account. Your payment reference should be your 10-digit personal tax reference (UTR), followed by the letter K e.g. 0123456789K.

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).

Your personal tax return for the tax year ending 5th April (e.g. 2022) needs to be submitted to HMRC by the following 31st January (e.g. 2023). However, we need to receive the information to prepare your tax return by 31st October to guarantee it being prepared before the deadline.
