A "tax-free weekend" is a designated period during which certain purchases are exempt from sales tax. These weekends typically occur before the start of the school year, allowing families to buy items like clothing, school supplies, and electronics without the added cost of tax. Each state may have different rules regarding what items qualify for the exemption. Many states in the United States, such as Texas and Florida, participate in tax-free weekends to help ease the financial burden on families. The specific dates and eligible items can vary, so it's important for shoppers to check their state's guidelines before making purchases.
