This guide outlines the three-year window for selling your old home and explains how to apply for your money back.

General Refund Form: Apply for a refund of overpaid LTT. Errors can happen during the tax filing process. This official online form is designed for taxpayers who have submitted a return but later realised they have paid more tax than was legally required, allowing for a straightforward recovery process.

Unsuitable Dwellings: Refunds for derelict or unsuitable properties. Properties that are deemed structurally unsound or "unsuitable for use as a dwelling" may qualify for lower non-residential tax rates.
