Is sales tax added on top or included?
In the US and Canada, sales tax is added at checkout — the sticker price is usually pre-tax. In most other countries, the price already includes tax.
What's the highest US sales tax rate?
Combined state + local rates can exceed 10% in parts of Louisiana, Tennessee, and Illinois. State-only max is around 7.25% (California).
Do I charge sales tax on services?
Depends on the state. Most states tax goods but not services, though a growing number tax digital services and SaaS. Check your state's rules.
