About
Value Added Tax (VAT) or Goods and Services Tax (GST) compliance is a daily task for freelancers and businesses operating internationally. A common friction point is extracting the tax component from a "Gross" total (e.g., a receipt that says $120 incl. tax). Standard calculators complicate this.
This tool simplifies the process with two modes: "Add Tax" (Net → Gross) and "Remove Tax" (Gross → Net). It features a comprehensive dropdown of global tax rates, allowing you to quickly switch contexts between UK VAT (20%), German VAT (19%), or Japanese Consumption Tax (10%) without manual lookup.
