What is Sales Tax? Understanding Consumption Taxes

A Sales Tax is a consumption tax imposed by state, provincial, and local governments on the retail sale of goods and services. It is typically collected by the seller at the point of sale and subsequently remitted to the taxing authority.

Retail Sales Tax (US)

Single-stage tax levied only on the final end-consumer at the register. Wholesale and business inputs with resale certificates are generally exempt.

Value Added Tax (VAT)

Multi-stage tax assessed on the incremental value added at each step of the production and distribution chain (common across the EU and UK).

Goods & Services Tax (GST)

Unified destination-based consumption tax applied comprehensively across nationwide goods and services (used in Canada, Australia, India, and New Zealand).
