Taiwan turned shopping receipts into lottery tickets in 1951; 75 years later, people still keep every bill hoping to win millions | World News

For most people, a shopping receipt is something that quickly disappears into a wallet, pocket or bin. In Taiwan, however, that small strip of paper has a very different role. A routine purchase at a supermarket, café or clothing store can also become an entry into a nationwide lottery, where receipts carry the possibility of winning thousands of dollars. The idea appears simple, but behind it is a carefully designed tax system that uses consumer behaviour to improve compliance. By giving shoppers a personal reason to demand receipts, Taiwan created a way for ordinary purchases to become part of the government’s effort to track business activity and reduce hidden transactions.The Ministry of Finance states that uniform invoice prize numbers are drawn for each two-month invoice period. The rules specify that winning numbers are drawn on the 25th of every odd-numbered month (January, March, May, July, September and November), meaning six draws annually. According to the Ministry of Finance, Laws and Regulations Retrieving System, Taiwan has moved toward electronic invoices, including digital carriers and mobile services. Consumers can store invoices electronically and check winnings digitally.

How a simple shopping Taiwan receipt turned into a chance to win big

A visitor shopping in Taiwan may notice an unusual habit at the checkout counter. Unlike in many countries where receipts are quickly discarded, shoppers in Taiwan often keep them because every official invoice carries the possibility of winning a cash prize. In many countries, refusing a receipt is common.The identification number printed on Taiwan’s uniform invoices is not just a transaction record. It can also become a lottery entry, giving consumers a reason to keep receipts they might otherwise throw away.The system has existed for more than seven decades and is still active today. Taiwan’s Ministry of Finance holds six receipt lottery drawings every year, with consumers able to win prizes from small amounts to a top prize of NT$10 million. The system has existed for more than seven decades. It was introduced in 1951 as a way to address a problem faced by many governments: businesses failing to report their full sales and underpaying taxes.

The tax problem Taiwan solved by changing customer behaviour

The challenge with indirect taxes is that governments often rely on businesses to accurately record transactions. When sales happen without receipts, authorities have limited visibility into the real level of economic activity. A shop that does not declare a sale can reduce the amount of tax it owes. Monitoring every individual transaction would require enormous resources, making enforcement difficult.Taiwan’s approach changed the relationship between customers and businesses. Instead of relying only on government inspections, it gave consumers a reason to request proof of purchase.If customers want a chance at winning, they need the receipt. If they ask for the receipt, businesses are more likely to record the sale properly. A simple reward system created a financial incentive for shoppers to help ensure transactions entered official records.

Why tax evasion is difficult to solve

Tax evasion is not unique to Taiwan. Governments around the world have long struggled with the gap between actual economic activity and what is reported to tax authorities.Traditional methods usually involve audits, penalties and inspections. These tools can work, but they are expensive and often reach only a portion of businesses. Tax authorities may never know about transactions that are deliberately kept outside official records.Economists have studied tax compliance for decades, examining how enforcement, penalties, income levels and social expectations influence whether people and businesses follow tax rules.A recurring problem is the information imbalance between taxpayers and governments. Businesses generally know more about their own sales than tax authorities do. The receipt lottery attempts to reduce that gap by making consumers part of the reporting process.Instead of asking only, “How can the government catch hidden sales?” , the system asks a different question: “How can customers be encouraged to make hidden sales harder?”

How Taiwan took the receipt lottery into the digital age

Although the original system depended on paper receipts, Taiwan has gradually moved towards digital versions.Many shoppers no longer need to keep piles of receipts at home. They can connect purchases to a digital account, scan a barcode before payment or receive notifications through mobile services if their receipt number wins. This shift has helped reduce paper waste while keeping the basic idea unchanged. The reward remains the same: consumers have a reason to make sure transactions are officially recorded.For many residents, checking winning numbers has become a normal part of daily life. Some people receive only small prizes, while others continue hoping that a routine purchase will eventually bring a much larger reward.Receipts can also be donated to approved charities. In those cases, organisations can claim any prize money linked to donated entries.

The tax experiment that spread beyond Taiwan

Taiwan’s model attracted attention from other countries looking for ways to improve tax collection.As reported by the Australian Broadcasting Corporation (ABC), several governments introduced similar receipt lottery programmes, including Brazil, Portugal, the Czech Republic, Lithuania, Romania and Slovakia. Mainland China also experimented with lottery receipts in various regions after seeing Taiwan’s experience.China’s adoption of the idea was linked to concerns over unreported economic activity and difficulties in capturing accurate business transactions. Research into these programmes suggested that encouraging consumers to request official receipts could increase tax reporting.The approach does not eliminate tax evasion, but it offers a different method of enforcement. Rather than depending only on government surveillance, it uses incentives to change everyday behaviour.
