CGT on overseas property after returning to UK

My wife and I have been resident abroad for 14 years. We own one property which is our sole residence. We do not own property in the UK. We intend to sell our house abroad and purchase a property in the UK and return to take up residence there. It may be that we buy the property in the UK before we have succeeded in selling the property abroad. If that is the case, are we creating a CGT liability if we subsequently achieve a sale.

I want to know the answer as well, thx

Hi cpdkalkan1, 
If you are resident in the UK when you dispose of the overseas property, you may have a capital gains liability.  Have a look at the guidance on private residence relief, which cover the periods where the property is your main residence.  As this property is overseas, you would be required to report the disposal on a self assessment tax return, even if there is no UK tax to pay.  If you dispose of the property before returning to the UK, there is no UK tax liability or anything to report.
Thank you.
