Landlord 2027 Tax + MTD Impact Calculator

See what the April 2027 property tax rates do to your own rental numbers, and when Making Tax Digital starts for you. For individual landlords in England, Wales and Northern Ireland.

The calculator works out your income tax for 2026-27 and for 2027-28 on the same numbers: once at the rates already in law (22%, 42%, 47%) and once at the rates announced at Budget 2026 on 28 October 2026 (24%, 44%, 49%, not yet law). It applies the mortgage interest tax reducer, the new 2027-28 order for the personal allowance, and the £100,000 taper.

Up to 20 properties with your ownership share on each, a £1,000 property allowance what-if, carried-forward finance costs, and a Making Tax Digital check with your start date and first-year quarterly deadlines.

You get an Excel and Google Sheets workbook, an offline browser version that saves and prints, and a quick-start guide with a worked example.
