Mortgage interest relief

Landlords are not permitted to deduct all of their finance costs from their property income to arrive at their property profits.

They instead receive a basic rate relief from their income tax liability on rental profits for their finance costs.

Finance costs includes mortgage interest, interest on loans to buy furnishings and fees incurred when taking out or repaying mortgages or loans. No relief is available for capital repayments of a mortgage or loan.

Where the rental profits are low, or are covered by personal allowance, the relief may be reduced to zero, with the balance of finance costs carried forward to a later year.
