Understanding Value-Added Tax (VAT) and Goods & Services Tax (GST)
Consumption taxes are an essential revenue mechanism implemented by over 160 nations worldwide. Regardless of whether a jurisdiction calls the levy Value-Added Tax (VAT) (prevalent across the United Kingdom and European Union) or Goods and Services Tax (GST) (standard in Canada, Australia, New Zealand, Singapore, and India), the underlying economic structure operates similarly:
Unlike a traditional retail sales tax (which is collected only at the final point of sale to consumer), VAT and GST are assessed incrementally at each stage of production and distribution. Registered businesses claim "input tax credits" on taxes paid for materials, ensuring only the net value added is taxed.
Calculating Tax-Exclusive vs. Tax-Inclusive Prices
A frequent source of invoicing errors is confusing tax-exclusive (Net) pricing with tax-inclusive (Gross) pricing:
1. Adding Tax to a Net Price
When you quote a base price and need to charge applicable tax on top, multiply the net price by the tax percentage:
2. Extracting / Removing Tax from a Gross Price
If you receive an all-inclusive retail receipt (such as $120 with 20% VAT included), you cannot simply subtract 20% of $120 ($24), which would yield an incorrect net price of $96. Instead, you must reverse the formula:
Dividing $120 by 1.20 yields the true Net Price of $100.00, meaning the actual tax paid was $20.00.

Frequently Asked Questions
To extract tax from a tax-inclusive (gross) price: Net = Gross / (1 + Rate / 100). The tax portion is Gross - Net. For example, with 20% VAT on a $120 gross price: Net = $120 / 1.20 = $100, and Tax = $20.
Both VAT (Value-Added Tax) and GST (Goods and Services Tax) are multi-stage consumption taxes levied on the value added at each step of production and distribution. While practically similar in economic function, different countries use different statutory frameworks and terminology.
