A large UK company has made a late payment of fees owed to my company. They paid interest on the late paid amount, as they are required to do so under the contract, but they deducted tax from that interest. How do I deal with that tax in my accounts?
Your customer should not have deducted tax from the interest it paid, as both parties involved in the transaction are UK resident companies trading in the UK. Companies used to have to deduct income tax from annual amounts of interest paid, but that requirement was removed from 1 April 2001 where the recipient is a UK company. Ask your customer to pay you the amount of interest it has withheld as ‘tax’. We can provide a longer explanation of the legal position if you need it.
