The tax office will open the first week of December for payment of property taxes for the year 2016. For those who have INAPAM cards there is typically a 50% discount on the predial, with the discount applied from the first peso up to whatever limit of assessed value they may set: last year this was 1.2 million pesos, after that, they charged the full amount of the remaining tax. For those seeking to pay the best document to bring is your paid receipt from last year. In my case I'll also have to bring copies of a couple of pages of my escritura, too, because the property is titled, and taxed, to the bank with which I contracted the fideicomiso. Since the discount is personal, and no bank or other corporation can claim it, I must be ready to show my connection to the property, each time. I'll take my Permanent Resident card and a copy, my INAPAM card and a copy, and those pages from my fideicomiso I spoke of which show my name. If the staff tell you you're not eligible for an INAPAM discount, because the value of your property exceeds the exempt amount, ask to speak with the tax office attorney. He will have the authority to work out a pro rata discount for you. Payment can be made online for those who are not seeking the INAPAM discount. https://ingresos.cancun.gob.mx/ Use Internet Explorer to access this website.
