Taxation in Taiwan
First conceived in the 1950s, the Taiwan government created a uniform invoice system to encourage honest reporting of sales and prevent underpayment of taxes by businesspeople. To provide an incentive, the government launched a receipt lottery system. Each receipt is coded with an alphanumeric number, and every two months a lottery drawing is held with prizes ranging up to NT$10 million (approximately $335,000 USD as of February 2012) depending on how many numbers match. The lottery is governed by the Uniform Invoice Award Regulations.
