HMRC Raises Late Payment Bills Interest Rates to 7.75% – Highest Since 2001: What You Need to Know

Following the increase in the Bank of England base rate to 5.25% on 3 August, the late payment and repayment interest rates will be adjusted accordingly for the main taxes and duties charged by HMRC. This comprehensive overview aims to provide taxpayers with a clear understanding of the financial changes that will impact them. 

Effective from 22 August 2023, the late payment interest rate will rise by 0.25% to 7.75%. This marks a notable shift, as it hasn’t reached such levels since August 2007, indicating a significant adjustment in the financial landscape. Additionally, the repayment interest rate will also increase from the current 4% to 4.25%, highlighting the evolving nature of tax regulations and their impact on financial transactions.

The Impact of Late Payment Interest On Your Taxes

The late payment interest is applicable to various tax bills, including income tax, National Insurance contributions, capital gain tax, corporation tax pay and file, stamp duty land tax, and stamp duty reserve tax. These interest rate adjustments will not only impact individual taxpayers but also shape the broader financial landscape. Furthermore, the corporation tax pay and file rate will increase to 7.75%, significantly affecting corporations and their tax obligations.

New Interest Rates for Underpaid and Overpaid Taxes

Regarding corporation tax self-assessment interest rates for underpaid quarterly instalment payments, the rate will rise to 6.25% from the previous 6%, emphasising the importance of fulfilling fiscal responsibilities in a timely manner. This policy change aims to encourage prompt payment and ensure accurate reporting.
Although the late payment interest rate now stands at 2.5% above the Bank of England base rate, HMRC remains committed to offering lower interest rates to taxpayers who have overpaid their taxes. This provides relief to those who comply with their tax obligations. With the rate increasing to 4.25% from 4%, taxpayers who have overpaid will experience a modest increase in their returns.

The Importance of Timely Payments

Furthermore, the interest paid on overpaid quarterly instalment payments and early payments of corporation tax that are not due by instalments will rise to 5% from the previous 4.75% starting from 14 August. This adjustment reflects the evolving economic landscape and emphasises the significance of accurate and timely payments.
These detailed changes in interest rates and their broader implications underscore the importance for taxpayers to stay informed and vigilant when managing their financial obligations. Adapting to these changes will ensure compliance while effectively navigating the intricacies of the tax system.
