How Making Tax Digital for Income Tax applies to rental income, the thresholds that matter, and what changes for your record-keeping.
MTD counts qualifying income as gross self-employment turnover plus gross rental income added together — not looked at separately. If you're a landlord with no self-employment income, it's simply your gross rents (before mortgage interest, letting agent fees, or any other expenses) that's tested against the threshold.
David rents out two buy-to-let flats generating £32,000 gross rent a year combined, and has no self-employment income. Because £32,000 is under the £50,000 threshold that applies from April 2026, he's not required to join yet — but once the threshold drops to £30,000 from April 2027 (based on his 2025/26 tax return figures), he'll be pulled in. Check exactly when with the MTD Income Threshold Checker, and see the tax impact with the Buy-to-Let Tax Calculator.
Each quarter you'll report rental income received and allowable expenses paid (mortgage interest relief works differently and is still handled via the Final Declaration, not the quarterly updates). This means genuinely digital, up-to-date records of rent received and expenses like repairs, insurance, letting agent fees, and service charges — not a shoebox of receipts sorted once a year.

Per landlord — all UK rental properties are treated as one property business for MTD purposes, so you submit one set of quarterly updates covering all of them, not one per property.
Each of you reports your own share of the gross rental income against your own individual MTD threshold, based on how the property income is split between you.
Furnished holiday lettings have historically had separate tax treatment; check current GOV.UK guidance for how they're being aligned with standard property income under MTD.
Yes — the quarterly updates report income and expenses, but mortgage interest relief (given as a basic-rate tax reduction) is still applied at the Final Declaration stage, not adjusted quarter by quarter.
