Frequently asked questions
Do freelancers charge sales tax on services?
Usually not — most states tax goods, not services. But rules vary by state and service type, so check your state's guidance.
What is the difference between sales tax and VAT?
Sales tax is charged once at the final sale; VAT is collected at each stage of production. The US uses sales tax, most other countries use VAT/GST.
Where do I find my local sales tax rate?
Your state's department of revenue publishes current rates, often with a ZIP-code lookup tool.
