All receipts in Taiwanese shops are similar to each other. Every receipt has its unique ID. For some people, this ID is a lucky number. Once in every two months, the the winner gets a prize through a lottery run by the government. Winners are announced on the website of the Ministry of Finance.
Why did the Taiwanese government turn receipt collection into the national game? The answer is very simple. This is how Taiwanese government ensures all businesses report their sales revenues to the state and thereby pay full tax. Why? Customers always demand their receipts in a bid to win the prize. This way, all purchased goods and services go through official billing procedure.
Some shops have even installed baskets for receipts collection.
Looking at this, I feel this “tax 2.0” practice has good chances to become the next big thing in fiscal policy of developing states.
