As of 2002, if you own only one property in Spain, you are allowed to file nonresident tax forms yourself. As of 2004, you are no longer fined if you don’t have a fiscal representative. However, the tax office does not send notifications of IBI tax to addresses outside Spain. If you don’t remember to pay your property tax every year, then when you eventually go to sell your house, you may find that the house has a large debt on it, if fines on unpaid taxes have built up. A fiscal representative serves as the contact person for the government, to ensure that the house remains free of debt.
