Planning on selling an apartment in Northern Ireland

Hi,
I am from Northern Ireland I moved to Dublin 9 years ago. Three years ago I bought an apartment in Northern Ireland as my main residence, however the last two years I have been renting it out. I am now looking to sell the apartment, anybody have any idea about what CGT I would have to pay?

If you've been in Dublin for 9 years and paying tax as a resident here it'll be a bit difficult to claim the northern property as your principal residence. Here you have a year after moving out from your PPR before you have to pay cgt, but i'm not sure about in the north. The good news though is that cgt is 20% here instead of the 40% it is there. If you're a resident here with an investment property there you would qualify to pay the Irish revenue 20% cgt. Could be a big saving considering how much prices have gone up in three years in the north. Check out the U.K inland revenue for information for overseas landlords. Whether you are already registered as an overseas landlord or not could make a difference. Where have you been declaring the rental income? Here or in the north?
