HMRC have announced that the official rate of interest will remain at 2.25% for 2024/25, despite the Bank of England Base Rate currently standing at 5.25%. The official rate of interest is used to calculate the income tax charge on the benefit of employment related loans and the taxable benefit of some employment related living accommodation. These rates used to fluctuate in line with base rate, and changed several times a year, but in recent years HMRC has fixed the rate for the whole tax year making the calculation of the taxable benefit easier to compute.
For those employers including beneficial loans on form P11d for 2023/24 the official rate to be used is 2.25%. The charge applies where the amount of the loan exceeds £10,000.
