Rent a Room tax calculator (UK) - MVP guide

A Rent a Room search often aims to find eligibility and thresholds. This MVP page provides an estimator entry point for incremental Income Tax from profit, and links you to what you should verify on official guidance for Rent a Room rules.

Why this is a guide, not a full calculator

Rent a Room scenarios often depend on eligibility rules and thresholds. A correct calculator must apply those rules accurately. This MVP does not model the full Rent a Room scheme.

How to use this MVP anyway

If you want a rough baseline, estimate your net profit and use the rental estimator as a simplified incremental Income Tax estimate. Then verify whether Rent a Room relief changes the outcome using official guidance.

Best next step

Use this as a starting point, and follow GOV.UK/HMRC guidance for scheme specifics.
