Tax stamps are official labels or stickers that indicate the payment of taxes on certain goods or services. They are often used for items like cigarettes, alcohol, and fuel to ensure that the appropriate taxes have been paid before the products can be sold to consumers. These stamps help governments track and regulate the sale of taxable items. When a product with a tax stamp is purchased, the stamp serves as proof that the seller has complied with tax regulations. This system helps prevent tax evasion and ensures that revenue is collected for public services. Tax stamps can vary in design and color depending on the jurisdiction and type of tax.
