Rental Profit & Section 24 Calculator

Overview

If you let property in your own name, your rental profit is added to your other income and taxed at your highest rate. Mortgage interest is no longer deducted – you get a basic rate tax credit instead – so higher rate landlords pay tax on money that goes straight to the bank. This workbook shows the real figures.
