HMRC has announced a reduction in the interest rates applied to overdue tax payments following a recent decrease in the Bank of England’s base rate. The Bank of England recently lowered its base rate from 4% to 3.75%, benefiting millions of borrowers and also impacting individuals with outstanding tax obligations to HMRC.
For self-assessment taxpayers, HMRC typically levies an 8% interest rate on late tax payments, but this rate will be reduced to 7.75% starting from January 9, 2026. Late payment interest is currently calculated as the base rate plus 4%, while the repayment interest paid by HMRC for overpaid taxes or refunds is being adjusted to 3.5%.
Repayment interest is determined as the base rate minus 1%, with a minimum limit of 0.5%. These adjustments are in response to the Bank of England’s base rate reduction and are set to take effect soon.
As the self-assessment tax return deadline approaches on January 31, it is crucial to file tax returns promptly to avoid penalties. Failure to file online by this deadline incurs an immediate £100 fine, which can escalate to daily fines of £10, up to a maximum of £900, for delays beyond three months. Subsequently, penalties increase to 5% of the tax owed or £300, whichever is greater, after six months and then again after 12 months.
Late interest charges commence from January 31 for any outstanding tax amounts, with additional penalties of 5% of the unpaid tax imposed after 30 days, and repeated at six months and 12 months. Individuals struggling to settle tax bills under £30,000 may qualify for a payment plan, known as “Time to Pay,” with HMRC.
Certain individuals, such as the self-employed, those with additional income sources, landlords, or high earners claiming Child Benefit, may need to submit a self-assessment tax return. It is essential to fulfill tax obligations promptly to avoid penalties and interest charges.
