• Let’s say you became self-employed in May 2020 and completed your first Self-Assessment return for the 2020/21 tax year.
  • Once you completed your return, HMRC calculated you owed £500 tax for the year, due by 31 January 2022. Your tax bill was under the £1,000 threshold, so you weren’t required to make payments on account for the following tax year.
  • During the following tax year (2021/22), you recorded higher profits and your bill for the 2021/22 tax year came to £2,000.
  • Because this is above the threshold, the payment on account process was triggered for the 2022/23 tax year.
  • Therefore, in addition to the £2,000 tax payment owed for the 2021/22 tax year, your tax bill also included your first payment on account for the 2022/23 tax year of £1,000 (half your 2021/22 tax bill).
  • So, you paid a total of £3,000 on 31 January 2023.
  • Your second payment on account of £1,000 for the 2022/23 tax year was made on 31 July 2023.
  • Now, in total, you have paid £2,000 towards your 2022/23 tax bill.
  • When you submit your Self-Assessment tax return for the 2022/23 year, and your tax bill comes to £1,800, for example, you’ll be owed a refund of £200 (the difference between the £2,000 you have paid on account and your actual tax bill).
  • In this case, your next payment on account for the following tax year, due 31 January 2024, would be £900 (half of your 2022/23 tax bill).

How to reduce payments on account

All business income can fluctuate from year to year.

If you know your tax bill is going to be lower than the previous year, say for example you have fewer clients or your tax relief has gone up, you can avoid overpaying tax by asking HMRC to reduce your payments on account.

You can choose to do this online or by post.

To do this online, sign into your online account. Select the option to view your latest Self-Assessment return, and then select ‘reduce payments on account’.

To apply by post, fill out the SA303 form on screen, print it, and send to the tax office.

Do think carefully before you reduce your payment on account because if it turns out you’ve underpaid, you’ll have to pay interest on the outstanding amount, which can increase your tax bill significantly.

Payment on account refunds

If you have paid too much tax, you’re entitled to claim a tax refund just like any other regular employee.

But as a Self-Assessment taxpayer, you claim a refund through the Self-Assessment process. This means any overpayments will be processed once you’ve submitted your next tax return.

Once HMRC has received your return, you’ll be told if you have overpaid.

You’ll be able to then choose how you want the money to be paid back to you, for example, by cheque or bank transfer. Alternatively, you can put it towards your next payment on account tax bill.

Final thoughts on payment on account

Now you understand how HMRC calculates payment on account, you should find it easier to anticipate your next tax bill.

For further support with this, ANY Accounting & Bookkeeping will be able to help you, if you have one.

But, as always, it’s best practice to submit your Self-Assessment tax return as soon as possible post tax year-end to give yourself enough breathing room to settle a balancing payment without incurring interest and late payment penalties.

Our expert accountants are on hand to help you – why not book in a free consultation with one of our team to discuss your situation? Our financial services are available nationwide, including: Accrington, Bamber Bridge, Buckshaw Village, Blackburn, Burnley, Chorley, Colne, Clitheroe, Darwen, Hurst Green, Lancaster, Lostock Hall, Longridge, Leyland, Penwortham, Preston, Skipton and the surrounding areas.

These are advance payments you make twice a year towards your Self-Assessment tax bill.
HMRC estimate how much tax you owe for the upcoming year based on your previous year’s tax bill. You pay this estimate over two instalment dates for the purpose of spreading out your tax payments throughout the year.

HMRC designed this process to help taxpayers stay on top of their payments as well as avoid paying tax in arrears.

You can calculate your upcoming payment on account by halving your previous year’s tax bill. Your actual tax bill won’t necessarily match the estimate, as business income generally fluctuates from year to year.

So, If your payments on account don’t cover your total tax bill for the year, you must make an additional ‘balancing payment’.

The two deadlines for paying your Self-Assessment tax are:

  • Midnight on 31 January (the same date your Self-Assessment tax return is due) for any tax you owe for the previous tax year (a balancing payment) and your first payment on account for the upcoming tax year.
  • Midnight 31 July for your second payment on account for the upcoming tax year.

As a Self-Assessment taxpayer, you’re required to make payments on account to HMRC unless you fall under one of the following two categories:

  1. Your last Self-Assessment tax bill was less than £1,000.
  2. 80% or more of your tax was deducted at source through PAYE.
