FAQ
What does a reverse tax calculator do?
It works backwards from a tax-inclusive total to calculate the pre-tax price and tax amount.
Can I enter my own tax rate?
Yes. Use the manual tax rate field when your invoice, state, province, or product category uses a different rate.
Is this a tax filing tool?
No. It is a calculation helper for price breakdowns and does not replace official tax guidance or accounting advice.
