On 6 February 2025, the Bank of England reduced the base rate from 4.75% to 4.5%. In response, HMRC has revised its interest rates for both late tax payments and repayments of overpaid tax.
New Effective Dates:
17 February 2025 – for quarterly instalment payments
25 February 2025 – for all other tax payments
How HMRC Interest Works:
HMRC interest rates are legally tied to the Bank of England base rate:
Late payment interest = Base rate + 2.5%
Repayment interest = Base rate − 1%, with a minimum floor of 0.5%
This structure ensures:
Prompt payment is incentivised by charging interest on overdue taxes.
Fair compensation is given to taxpayers when HMRC owes refunds.
Why This Matters to You?
If you have outstanding tax liabilities, your interest cost will now be slightly lower.
If HMRC owes you a repayment, the interest paid to you will also be reduced.
If you're paying tax in instalments (e.g. Corporation Tax), the new rates apply based on the above dates.
Planning Tip: Even with this rate reduction, late payment interest still adds up. Paying on time remains the most cost-effective option.
