GST vs sales tax vs VAT
Goods and services tax (GST) and value-added tax (VAT) are multi-stage consumption taxes with input-tax credits for registered businesses. Sales tax (common in the United States) is typically charged once at retail. This calculator focuses on single-rate GST/VAT math — verify exemptions and filing rules with your local revenue authority.
