I sold my holiday home in the US at the end of March 2019 and I am aware I need to declare this on my UK tax return as I am UK domiciled and resident.
I have used an accountant in the US who has advised that my US taxes won't be dealt with until next year however I would like to complete my UK tax return now.
Question is how do I know what US tax I can offset against the UK tax if this Won't be dealt with until next year. When I sold the property a percentage was withheld over there which I can claim back next year minus the tax I owe.
As I wont know the tax by the time I submit my UK tax return, do I simply have to pay full UK tax on the gain and amend my tax return once I have had the US tax position confirmed so that it can then be offset? The UK gain is approx £95k.
