The rule that changed how individual landlords are taxed on mortgage interest. What it does, who it affects, why some landlords pay more tax than their profit suggests, and the questions it raises.
Individual landlords used to deduct mortgage interest from rental income before working out their tax. Under what is usually called Section 24, that deduction was replaced by a tax credit at the basic rate of income tax, phased in over several years.
For basic-rate taxpayers the effect is often small. For higher-rate landlords it can be significant, because the relief they receive is now limited to the basic rate.
Because the interest is no longer deducted before income is calculated, a landlord's taxable income can look higher than their actual profit. That can push someone into a higher tax band, or affect things linked to income, such as child benefit.
