Given the fact that nobody is going to find a tax inspector standing on their doorstep asking to see, tot up and count their receipts (which takes many hours), it is all thoroughly moot and totally ridiculous. Everyone will just declare an amount for their receipts that suits their tax return, as they have done for years, even if they have just one receipt for pita with gyros. Another typically Greek unworkable scheme. This country is run by a laughable bunch of utter loons.
