如何使用
01常见问题
02When should I use Add Tax versus Remove Tax?
Use Add Tax when you have a pre-tax amount. Use Remove Tax when the amount already includes tax and you need the pre-tax value.
Does this know my local tax rate?
No. Enter the rate yourself because VAT and sales-tax rules vary by location, product type, and exemption.
Can I use this result as financial advice?
No. The result is an informational estimate based on the values you enter. Check the math, fees, taxes, and local rules before making financial decisions.
