Non Resi Company selling UK residential property - straight line basis

We are a non resi company selling a UK residential property and wish to use the straight line election. Do I calculate the gain as normal, including indexation allowance from the date of purchase many years ago to Dec 2017, then time apportion that total gain?

Hi Jack

We do not answer capital gains queries on this forum however the more detailed guidance for a non-resident UK selling a UK residential property is here:
Work out your tax if you're a non-resident selling UK property or land - GOV.UK (www.gov.uk)
CG73788 - Non-Resident Capital Gains Tax (NRCGT) – Disposals on or after 6 April 2015 to 5 April 2019: Individuals: Special rules, and computation: Election for 'straight-line time apportionment' basis of computation

Thanks
