Reverse Sales Tax Calculator

Free reverse sales tax calculator for Canadian contractors. Enter a tax-included total and province to see the pre-tax amount and tax paid, separately. Unlike a basic GST/HST calculator, this one also handles PST, RST, and QST where they apply on top (BC, Saskatchewan, Manitoba, Quebec). Covers all 13 provinces and territories, no signup required. Built by StrikeHoney, field service management software for Canadian trade contractors.
