What you have just said has thrown me into a tizz trying to understand what you have said. Could you please give a bit more practical details. Say I want to claim rent/transport/medical expenses. Will doctors, car rental place and landlords all issue me an electronic receipt?
Not from Mexico, so it might be different for them, but one way how this works in some places is that the tax office gets all the electronic receipts from all the cash register/POS systems anyway, since that's how they monitor sales/vat/excise/etc taxes paid by the merchant and reduce the risks of "under the counter" sales where fake receipts are issued but taxes not paid on the sale.
So if the doctor's office punches in my legal ID number with the receipt (or if the ID gets added automatically from the billing system that a large hospital would have), then when the office sends all their receipt files to the tax office, the tax office will automatically add that electronic receipt to my tax deduction.
Yes. Not all spending can be deducted. But for the ones you do, you have the right to ask for the "electronic invoice" and the business has to give it to you.
When that happens they ask you for your TAX ID and then the business generates the invoice and your taxid and their taxid makes the tie. The Mexican IRS systems see all of this. So at the tax reporting moment, the system will have all that info.
It is pretty neat actually. However I think it is possible bc in Mexico people are not that concerned with privacy and all that.
