Global Sales Tax & VAT Calculator
Enterprise-grade financial tool for calculating Sales Tax, VAT, and GST. Features a database of 100+ regions, reverse tax calculation, and multi-item receipt generation.
About
Precision in financial transactions is non-negotiable. This utility is engineered for merchants, accountants, and international buyers who require exact tax computations across varying jurisdictions. Unlike basic calculators that assume a single global rate, this tool integrates a comprehensive database of US State Sales Taxes, European VAT, and APAC GST rates.
Key capabilities include Forward Calculation (Net to Gross) for pricing strategy, and Reverse Calculation (Gross to Net) for extracting tax liabilities from total receipts. The Multi-Item Receipt Generator simulates a Point-of-Sale (POS) terminal, allowing the aggregation of taxable and non-taxable line items into a single audit-ready summary. Correctly applying rates such as the 20% UK VAT or the 7.25% California base rate prevents compliance errors and margin leakage.
Formulas
The tool processes values using standard accounting rounding (Banker's rounding usually, but standard half-up is used here for consumer consistency).
1. Net to Gross (Forward):
2. Gross to Net (Reverse):
Used when the price already includes tax (e.g., VAT-inclusive pricing).
3. Weighted Average Tax (Multi-Item):
