1. What is BC Reverse Sales Tax Calculation?

The BC Reverse Sales Tax calculation determines the original price before tax was added, given the total amount paid and the tax rate. This is particularly useful for British Columbia's 12% combined sales tax (PST + GST).

2. How Does the Calculator Work?

The calculator uses the reverse tax formula:

Where:

• \( \text{Total Amount} \) — The final amount paid including tax (CAD)
• \( \text{Tax Rate} \) — The combined tax rate (0.12 for BC's 12%)

Explanation: The formula works backward from the total amount to find the original price before taxes were added.

3. Importance of Pre-tax Calculation

Details: Knowing the pre-tax amount is essential for accounting, expense reporting, budgeting, and understanding the true cost of goods and services before taxes.

4. Using the Calculator

Tips: Enter the total amount paid in CAD and the tax rate as a decimal (0.12 for 12%). The calculator will show the original price before tax.

5. Frequently Asked Questions (FAQ)

Q3: What if I only know the tax amount?
