What are HMRC’s Late Payment Interest Rate Changes?
Introduction
Managing tax liabilities effectively is crucial to avoid unnecessary penalties and interest charges. The UK tax landscape is constantly evolving, with HMRC adjusting interest rates on underpaid and overpaid taxes in line with changes in the Bank of England’s base rate.
Following the Bank of England’s recent base rate reduction to 4.5% on 6 February 2025, HMRC has announced corresponding adjustments to its late payment and repayment interest rates. These changes, effective from 17 February 2025, impact both individuals and businesses managing tax payments.
In this blog post, we will break down the new late payment interest rates, discuss the impact on businesses and taxpayers, and provide actionable strategies to stay compliant and minimise tax liabilities.
New HMRC Interest Rates from February 2025
As of 17 February 2025, the revised interest rates for corporation tax and other HMRC taxes are:
Corporation Tax (Quarterly Payments)
- Late payment interest rate: 5.5%
- Interest on overpaid tax: 4.25%
Other HMRC Taxes (Effective from 25 February 2025)
- Late payment interest rate: 7%
- Interest on overpaid tax: 3.5%
These rates apply to various taxes, including Income Tax, VAT, Capital Gains Tax, Inheritance Tax, and National Insurance Contributions.
Why Do HMRC Late Payment Interest Rates Matter?
HMRC’s late payment interest rates penalise taxpayers who miss deadlines. With the current high interest rates, delaying payments could result in significant financial burdens.
- Business owners with overdue corporation tax or VAT payments will now face a 7% charge on outstanding balances.
- Self-employed individuals and landlords failing to settle tax liabilities will also see increased penalties.
- Conversely, overpaid tax refunds now earn interest at 3.5%, slightly improving cash flow for businesses receiving tax rebates.
Example:
If a business owes £50,000 in overdue corporation tax and fails to pay for 30 days:
- At the new 7% interest rate, the business incurs an additional £287 in interest.
- If delayed for three months, the interest could exceed £850.
Strategies to Minimise Tax Penalties & Interest
Given these changes, proactive tax planning is crucial. Here’s how Merranti Accounting can help:
1. Stay Ahead of Payment Deadlines
Avoid penalties by paying your tax on time. Our accounting team can assist with: Tax return filing – ensuring all liabilities are calculated accurately and submitted before deadlines.
Payment reminders – automated alerts to prevent missing due dates.
Real-time financial tracking – so you always know your tax liabilities.
Key Dates to Remember in 2025
- 31 January 2025 – Self-Assessment Tax Return & first payment on account due.
- 3 March 2025 – 5% late payment penalty for outstanding 2023/24 tax.
- 31 July 2025 – Second Self-Assessment payment on account due.
2. Use HMRC’s Online Calculator
To estimate late payment interest, use HMRC’s online interest calculator. This helps determine potential penalties and strategise accordingly.
3. Explore Time to Pay Arrangements
If cash flow is tight, HMRC offers a Time to Pay (TTP) arrangement, allowing businesses and individuals to spread payments over time.
Merranti Accounting can negotiate with HMRC on your behalf to secure flexible payment terms.
4. Plan Tax Payments Proactively
The high late payment rates highlight the importance of tax forecasting and budgeting. Our tax planning services ensure: ✔ Corporation tax and VAT estimates are accurate.
Cash flow forecasts help allocate funds for tax liabilities.
Deductions and reliefs are maximised to reduce overall tax obligations.
5. Leverage Overpayments for Cash Flow
Since HMRC pays 3.5% interest on overpaid taxes, businesses with strong cash flow could make advance payments and earn interest rather than holding cash in low-interest bank accounts.
