Apologies of this has been asked before-I had a look through some posts but couldn’t see a relevant one. We have a property in London which has been rented out for a year (it was our primary residence for 6 years). We emigrated to Aus in August this year and have decided to sell and use the money to buy a property here. If it sells for market value less the improvements etc we won’t have any capital gains but my question is will we have to pay tax on the amount we transfer out here even though we haven't made a gain on it?
