Sales Tax
A government-imposed tax on the sale of goods and services, collected by the seller.
Definition
Sales tax is a consumption tax imposed by state and local governments on the sale of goods and certain services. As a seller, you're responsible for collecting the appropriate tax amount from customers and remitting it to tax authorities. Sales tax rates and rules vary significantly by jurisdiction—some states have no sales tax, while others have rates exceeding 10%.
Proper sales tax collection requires knowing: which products/services are taxable, what rate applies based on the buyer's location (destination-based) or your location (origin-based), and any exemptions that might apply. This complexity increases for businesses selling across multiple jurisdictions.
Why It Matters
Sales tax compliance is a legal obligation with serious consequences for errors. Under-collecting means you owe the difference from your own pocket. Over-collecting creates customer complaints and potential legal issues. Non-compliance can result in audits, penalties, and interest charges.
For invoicing, properly calculating and displaying sales tax builds customer trust and ensures compliance. Most modern invoicing systems can automatically calculate sales tax based on location, but you're ultimately responsible for accuracy.
