A tax stamp is a government-issued label or sticker that indicates that a specific tax has been paid on a product or service. These stamps are often used for items like tobacco, alcohol, and certain luxury goods, ensuring that the appropriate taxes are collected before the products are sold to consumers. Tax stamps serve as a form of revenue collection and help prevent tax evasion. They can also provide information about the product, such as its origin and authenticity. In some cases, tax stamps are required by law to be affixed to packaging, making them an important aspect of regulatory compliance in industries like tobacco and alcohol.
