Payments on account are a type of advance payment that you might need to make towards your Self Assessment tax bill. In this article we explain who might need to make payments on account, and what they are.

Starting with Self Assessment

What is a payment on account?

Do I need to make payments on account?

What is a balancing payment?

How do I make payments on account?

Can I reduce my payments on account?

What if I can’t afford to make payments on account?

When you’re self-employed, the tax and National Insurance that you owe isn’t automatically deducted from your pay like it is with PAYE. Instead, you need to tell HMRC about what you’ve earned by filling out a Self Assessment tax return so they can calculate how much you owe.

When do I need to submit my tax return?

You can submit your return once the tax year that you’re reporting on has ended (tax years run from 6th April one year until 5th April the next). The deadline to submit your return depends on whether you submit online or using a paper form:

When should I pay my Self Assessment tax bill?

The final deadline to pay the full amount that you owe through Self Assessment is 31st January, following the end of the tax year that it relates to.

For example, if you need to submit a return for 2022/23 tax year (6th April 2022 – 5th April 2023) you’ll need to submit your tax return and pay the full amount you owe by 31st January 2024.

If your tax bill is more than £1,000 though, you might need to make payments on account (which, if you’re not expecting it, can be an unpleasant surprise).

Essentially, payments on account are advance payments that you make twice a year towards the following year’s tax bill. It means that as well as paying the bill for 2022/23, you’ll need to pay half of your expected tax bill for the 2023/24 tax year by 31st January 2024. The second half of your expected bill is due by 31st July 2024.

How do I know what next year’s expected tax bill is?

HMRC work on the assumption that next year’s bill will be exactly the same as this year’s. So, if your tax bill this year is £3,000, your first payment on account will be £1,500. It’ll get easier, but the first payment is a bit of a killer if you’re paying tax before you’ve even earned the income.

Not everyone does! You’ll need to make payments on account if:

For example

Gemma’s Self Assessment tax bill for 2022/23 is £5,000. She needs to pay this in full by 31st January 2024. Because her tax bill is more than £1,000, Gemma will also need to make payments on account towards her bill for 2023/24.

The first payment on account is 50% of what she owes for 2022/23 (50% of £5,000 is £2,500). So, before the payment deadline on 31st January 2024 she’ll need to pay:

  • £5,000 for 2022/23
  • £2,500 as a payment on account for 2023/24

Gemma will need to make the second payment on account for 2023/24 by midnight on 31st July 2024.

You’ll also see the phrase ‘balancing payment’. These are payments that you might need to make if your predicted earnings don’t match your actual earnings.

Payments on account are made on the basis of predicted earnings, and simply assume that next year’s income will be the same as this year’s. In reality your earnings are likely to fluctuate, so if your payments on account don’t cover the tax owed on your actual earnings, you’ll need to top them up with a balancing payment.

For example

Using Gemma as an example again, she made two payments on account totalling £5,000 towards the 2023/24 tax year.

When she actually submits her tax return for that year the bill comes to £5,500, so before the payment deadline on 31st January 2025 Gemma will need to pay:

  • A balancing payment of £500 for her 2023/24 tax bill
  • The first payment on account towards 2024/25, which will be £2,750 (half of £5,500)

You can make payments on account in the same way that you normally pay your Self Assessment tax bill. There are several methods available, such as through online banking, over the phone, or even by setting up a Direct Debit.

If you sign into your Personal Tax Account you can see how much you’ve already paid, and what’s left to pay.

Being self-employed can be unpredictable. Some years you do very well and make plenty of profit, whereas other years you earn substantially less. If you’re aware that your tax bill will be lower in the coming year than it was for the last one, you can ask HMRC to reduce your payments on account.

Be careful here though: don’t be tempted to cut your payments on account by too much. If you end up earning more than you thought, resulting in an underpayment, HMRC can charge you penalties and interest. For this reason, it may be better to overpay your tax and ask HMRC for a refund later.

If you do want to reduce your payments on account, you’ll be given the option to do this when you go online to complete your Self Assessment. Just select “Reduce Payments on Account”. Alternatively, you can download, print, and send an SA303 form to your tax office.

Will I ever not need to make two payments on account?

You don’t need to make two payments on account in the year if:

We strongly recommend putting money away throughout the year to cover your tax bill. Unfortunately, it’s not unusual for people to be caught out by payments on account the first time they encounter them.

After all, if you’ve never heard of them, suddenly learning that you’ll now need to pay half of next year’s tax bill when you pay this year’s bill can be a horrible shock. If you’re having genuine problems paying, you might be able to make a Time to Pay agreement with HMRC.
