Exemptions

You do not have to register if any of the following apply:

• where no gain arises from a disposal because sales proceeds equal the acquisition cost

• the substantial shareholding exemption applies to a disposal

• the disposal is a grant of a lease for no premium

• the disposal has an appropriate connection to a CIV  and relief is provided under the terms of the relevant Double Taxation Treaty — HMRC is applying a concessionary treatment to these disposals which is subject to review

There is no need to register unless there’s a disposal of an interest in UK property or land. Holding an asset does not mean a non-resident company needs to register for Corporation TaxTax.
