What You'll Gain from This Guide

Capital Gains Tax on property is one of the highest-risk areas of UK tax compliance — not because it is complex, but because deadlines are strict and errors are unforgiving. This guide is designed to prevent those failures. It explains when a disposal triggers CGT, what counts as a disposal (including gifts and transfers), and why CGT is assessed at completion rather than exchange. You’ll learn how a property gain is calculated at a high level, which acquisition and disposal costs are allowable, and why confusing repairs with capital improvements is a common and costly mistake. The guide also covers the now-minimal annual exempt amount, higher CGT rates for residential property, and the mandatory 60-day reporting and payment rule that applies even if you file Self Assessment. Particular attention is given to jointly owned property, where each owner must report and pay separately. By following the CGT control framework in this guide, landlords gain confidence that disposals are identified early, gains are calculated correctly, and reporting is completed on time — reducing HMRC risk at a point where scrutiny is highest.

Part of the Property Tax Compliance Pack

This guide forms part of the Property Tax Compliance Pack, a structured collection of tools designed to help landlords meet property tax obligations confidently and without surprises. This guide focuses on Capital Gains Tax on personally held UK property. Other guides in the pack cover rental income tax, Section 24 mortgage interest restrictions, record-keeping discipline, and compliance triggers so property tax is managed as a connected system rather than isolated events. Each guide works independently, but together they provide a complete compliance framework for UK landlords.

Avoid Penalties When You Sell

Property CGT errors are expensive, visible, and often irreversible once deadlines pass. This guide gives you a clear framework to calculate gains properly, meet the 60-day rule, and report disposals with confidence.
