Frequently Asked Questions
What is the difference between Sales Tax and VAT?
Sales Tax is collected only at the final sale to the consumer. VAT is collected at every stage of production and distribution. However, for the final consumer, the calculation method is often the same (percentage added to price).
How do I calculate tax backwards?
Use the "Remove Tax" mode. The formula is: Total Price ÷ (1 + Tax Rate). For example, if Total is $110 and Tax is 10%, Net = 110 ÷ 1.10 = $100.
Can I use this for GST?
Yes! GST (Goods and Services Tax) works exactly like VAT. Just enter your local GST rate (e.g., 10% for Australia, 5% for Canada) to calculate.
