Understanding GST / VAT addition and subtraction
Goods and Services Tax (GST) and Value Added Tax (VAT) are standard indirect consumption taxes. Adding tax multiplies the base price (Net) to determine the tax: Tax = Net × Rate / 100.
Removing tax from a total (Gross) uses the division index formula: Net = Gross / (1 + Rate / 100). Subtracting raw percentages directly is incorrect due to base changes.
