UK Landlord Tax Guide 2026/27

Why this one

Landlord taxation changed substantially between 2017 and 2025, and a great deal of the advice still circulating describes rules that no longer exist. This guide covers how rental profit is actually worked out now, why mortgage interest is not an expense any more, and the handful of decisions where getting it wrong costs thousands rather than tens of pounds. Every rule is worked through with real arithmetic, because the interaction between the bands and the interest reducer is where the money hides.
