Losses
What happens if I make a capital loss on the disposal of my foreign property?
If you are Irish resident or ordinarily resident and Irish domiciled you can set the loss against other capital gains, other than gains made on the disposal of Irish development land. If you have no capital gains in the year of disposal, you can carry the loss forward against future gains. You cannot set your capital loss against income such as employment, rental or investment income.
Sorry I was incorrect in my last post, I was thinking of foreign rental income losses, I copied the quotation from the revenue website on CGT but it took a bit of searching.
