Goods and Services Tax (GST)
Abbreviation: GST
Pronunciation: goods and SUR-vuh-siz taks (JEE-ES-TEE)
Also known as: Goods & Services Tax, GST
Definition
Goods and Services Tax (GST) is a broad consumption tax used in several jurisdictions and applied to many supplies of goods and services. In tax calculation and e-commerce compliance, it commonly covers taxable supply rules, registration thresholds, place-of-supply rules, rates, exemptions, invoicing, collection, and remittance. GST is jurisdiction-specific and should not be treated as a universal synonym for every sales tax or VAT system. Operationally, teams should determine the customer and supply location, apply the correct tax treatment, retain evidence, and keep tax calculations auditable.
