Best MTD Software for Landlords: What Property Owners Actually Need

July 4, 2026 3 min read

Quick answer: The best MTD software for landlords tracks rental income and expenses property-by-property, correctly handles the mortgage interest tax credit, keeps a live tax estimate, and files quarterly property updates to HMRC.

Landlords face a particular challenge under Making Tax Digital: property income must be reported separately, and with multiple properties the admin multiplies fast. The right software makes this effortless; the wrong one makes it worse.

Why do landlords have unique MTD needs?

Unlike a sole trader with a single income stream, landlords must keep clean digital records of rent received and allowable expenses, and the residential mortgage interest restriction changes how finance costs are treated. Get the fundamentals right with MTD for landlords and tracking rental income and expenses.

What features should landlords look for in MTD software?

  • Automatic bank import so rent and costs are captured without manual entry.
  • Correct categorisation of allowable expenses ,repairs vs improvements is a classic trap. See landlord allowable expenses.
  • Multi-property handling if you have a portfolio. Read MTD for landlords with multiple properties.
  • Correct mortgage interest treatment ,residential finance costs give a basic-rate tax credit, not a full deduction.
  • A live tax estimate so finance costs and reliefs don’t catch you out at year end.

Are accidental landlords affected by MTD?

Yes ,often without realising it. If you inherited a property, or moved in with a partner and let out your old home, you may be in scope once your property income is combined with any other income. Our guide to MTD for accidental landlords explains who qualifies and what to do, and MTD landlords under the threshold covers smaller portfolios.
