I invested €50,000 in an Irish property development in early 2007. The property company subsequently went into receivership, in 2010. All of its apparently reduced assets were sold, including an agricultural site, and all the money from the sale went to one of the banks, which had been the principal creditor. I, and a group of private individuals, lost all our investment. My question is probably naive: can I set any of my 50k loss against my income tax liability, and if so, for how many years after the loss? Thank you, folks.
