Inherited an asset?
There’s no CGT when you inherit — inheritance tax rules apply instead. CGT only enters when you later sell, measured from the value at the date of death. Knowing this changes what many families decide to do.

On the profit — the gain — when you dispose of certain assets such as second properties, shares or business assets, not on the full sale price. Your main home is usually exempt through private residence relief.
Not on inheriting — that falls under inheritance tax rules. CGT applies only if you later sell, and the gain is measured from the asset's value at the date of death.
Use the annual exempt amount, time disposals across tax years, transfer assets between spouses before selling and claim every relief available. Planning before the sale matters most.
Yes — non-residents are within UK CGT on disposals of UK property and must report them to HMRC under special deadlines. We handle the calculation and the reporting.
