Understanding American Sales Tax
The sales tax in America is a value added tax on most sales of goods and services. The percentage of the tax depends which state the transaction is being processed in, as each state can have a different local tax rate.
Some states participate in tax-free shopping, and some have sales tax holidays, so make sure you're aware of when these are if they apply to you.
If you’re a business or an organisation, you’ll need to be aware of federal state and local tax rates and requirements to file taxes correctly and pay on time.
Organisers are solely responsible for correctly charging, collecting, filing and paying their taxes each year.
