Understanding Sales Tax
Sales tax is a consumption tax imposed by state and local governments on the sale of goods and services. After the Supreme Court's 2018 decision in South Dakota v. Wayfair, states can require out-of-state sellers to collect sales tax based on economic nexus thresholds.
Most states have set their economic nexus threshold at $100,000 in sales or 200 transactions per year. If you exceed these thresholds in a state, you typically need to register for a sales tax permit and begin collecting tax from customers in that state.
Use our tools to calculate accurate tax rates, track your nexus obligations, and estimate your quarterly tax payments. Stay compliant and avoid penalties with our comprehensive sales tax resources.
