Reverse Tax Questions

How do I calculate the pre-tax price from a total? ▾

Enter the total amount you already paid — the one that includes tax — and select your province or state. The calculator works backwards through the tax formula to show the original subtotal and the exact tax amount.

Why would I need to reverse-calculate sales tax? ▾

This is useful when a receipt or invoice only shows a total and you need the pre-tax cost — for expense reports, bookkeeping, or splitting a bill where tax needs to be backed out separately.

Is reverse tax calculation exact? ▾

Yes. The calculator works backwards through the same rounding rules used for the forward calculation, so the result matches what a forward calculation on that subtotal would have produced, to the cent.

Can I go the other direction, from subtotal to total? ▾

Yes — use the sales tax calculator, linked at the top of this page, to add GST, HST, QST, PST, or US sales tax to a subtotal.
