I bought my house in December of last year and as far as I was aware had paid all the taxes, now 5 months later I have a letter from the Hacienda saying that we have to pay another 10,440.00 euros, the reason being we paid 173,000 for the property and they say that they value it at 320,00 so me must pay tax an the value of the house and not the price that we paid for it. surely they must understand that in the current climate people are selling the properties cheaper as it is the only way they will sell. I can't see how we are liable for the tax?
