Late Payment of Tax Becomes Expensive

Following the Bank of England’s announcement on 2 February 2023 that the base rate will rise to 4%, HMRC’s interest rates are also increasing by 0.5%, to 6.5% for late payment interest.

The rates, which apply to the main taxes and duties administered by HMRC, track the base rate. The late payment rate is set at 2.5% above the base rate. The repayment rate is set at a ‘minimum floor’ of 0.5% until the base rate reaches 1.5%, it then increases with the base rate.

Those who have elected to pay inheritance tax by instalments may wish to reconsider the viability of their strategy given recent rises.
