Loss made on sale of Polish property


Frequent Poster
Hi I sold 3 Polish properties in 2012 at a loss of approx. 180k euro.
Up until sale I had being making returns on my Irish tax form 11 for rents made on those properties.
However I never reported to revenue making a loss on the sale but I can prove it with documentation if required.
Things have turned around for my Irish properties and I am now wondering if I can use those losses to offset Capital Gains tax here in Ireland?
Also I am due to inherit money from an uncle in the USA so would I be able to offset against that?
