UK sets claims process for treaty relief after interest withholding failures

Income Tax Act 2007 section 874 requires specified payers to deduct Income Tax when paying yearly interest arising in the UK, subject to statutory exceptions. A double-tax agreement may restrict the UK tax charge, but the new process applies only where the payer lacked an effective HMRC direction permitting reduced or nil deduction when the payment was made.^[1][4]

Treaty conditions still have to be met

The route is available where the overseas lender was beneficially entitled to the interest, resident in a treaty jurisdiction and satisfied the relevant treaty conditions, but the payer deducted nothing or too little. Whether a deduction occurred is a question of fact: a contractual gross-up clause does not itself show that tax was deducted. HMRC says contemporaneous payment records may be needed to distinguish a gross payment from net interest accompanied by a gross-up.^[2]

Payer and lender claims are different

Where no deduction was made, HMRC treats the payer as liable for the Income Tax charge and will consider the payer’s treaty-relief claim. The lender cannot claim repayment merely because it received the gross interest: it has suffered no deduction. If tax was actually deducted, the lender must use the existing repayment route instead.^[1][2][6]

Outside-return claim and evidence

The payer’s claim is made outside a return using HMRC’s new form. It must identify the payment, lender, treaty article and rate claimed, and include residence evidence, a beneficial-ownership declaration and confirmation of the deduction failure. Separate forms are required for each lender and loan, although one form may cover multiple payments under the same loan. A company’s declaration must be signed by an officer.^[1][3]

Four-year limit does not remove default consequences

Taxes Management Act 1970 section 43 gives a four-year limit after the end of the relevant assessment year. Repayment also requires documentary proof that the tax was paid. HMRC may enquire into the claim, charge late-payment interest and penalise inaccuracies. Groups should disclose failures promptly, preserve payment evidence and test treaty entitlement before claiming; the guidance does not make treaty relief automatic or remove the underlying withholding duty.^{[1][2][3][5][6]}
