On 31 July 2024, second payments on account of 2023-24 Income Tax and Class 4 National Insurance liabilities fall due. This year, there’s potentially more to consider than usual.
Payments On Account (POAs)
POAs for 2023-24 are due for individuals within self-assessment unless:
- Income Tax and Class 4 National Insurance Contributions (NICs) due under self-assessment for 2022-23 was less than £1,000.
- More than 80% of the Income Tax and NI owed for 2022-23 was deducted at source.
The Payment dates for 2023-24 POAs are 31 January and 31 July 2024.
Reducing POAs
POAs are based on the previous year's tax liability. Where an individual’s 2023-24 Income Tax and NI liabilities are expected to be less than 2022-23, they can make a claim to reduce their 2023-24 POAs.
This reduction can made by filing the 2023-24 tax return by 31 July 2024, or by a separate application to HMRC by post or online.
Key points to remember this year
- It is important to pay on time: Interest is charged on late payments at 7.75%.
- This is the highest rate for nearly 17 years.
- Where a claim to reduce POAs is fraudulent or negligent, HMRC can Charge a penalty.
- The maximum penalty is the difference between the payment that should have been made and the amount paid.
- When estimating 2023-24 tax liabilities, do not forget to factor in the effect of Basis period reform.
- This may result in more income being taxable in 2023-24 than would otherwise have been the case.
