Wolfram Computation Meets Knowledge

Why am I being charged sales tax?

Wolfram Research charges tax where it is required to do so based on your location and various state laws. Your location is determined by the billing address you provide with your payment method. Customers who are not charged tax should remit use tax as required by their state law.

Sales tax rates vary from state to state and change over time. Please check with your state department of revenue for the most current sales tax rates.
