One of the most commonly used and valuable exemptions from Capital Gains Tax (CGT) is for the sale of a family home. Generally, there is no CGT on a property that has been used as your main family residence. However, an investment property that has never been used as your main home will not qualify. This relief is known as Private Residence Relief (PRR).

The rules change if you live abroad. Since April 2015, non-UK residents are subject to CGT on the sale of UK residential property. Only the portion of the gain made after 5 April 2015 is liable for tax. In certain situations, PRR may still apply if the property was the owner’s only or main residence.

If a UK non-resident sells UK residential property, they must submit a non-resident CGT (NRCGT) return and pay any CGT within 60 days of the sale. This return is required even if no CGT is due, or if there is a loss on the sale, and regardless of whether the taxpayer will report the sale on their self-assessment tax return.

There are penalties for not filing the NRCGT return on time or for failing to pay any tax owed by the deadline.
