I completed on my property 2 years ago and paid my wealth tax for the first time last year. A friend helped me complete the form 214 but having found this website I realise that I overpaid the Renta part. This was calculated @ 2% of the valor catastral instead of the 1.1%. When completing the form this year could I deduct the overpayment from this year’s payment or is it lost for ever? Great website.
