The Quebec Sales Tax (QST) is a provincial tax applied to most goods and services in Quebec. Here’s how to calculate it:

Current Quebec Sales Tax (QST) Rate:

• QST: 9.975% (as of 2025)
• GST (Federal Tax): 5%
• Combined Tax (QST + GST): 14.975%

How to Calculate QST:

1. Determine the pre-tax amount (e.g., $100).
2. Calculate QST:
   [
   \text{QST} = \text{Pre-tax amount} \times 0.09975
   ]
   Example: $100 × 9.975% = $9.98
3. Calculate GST (if applicable):
   [
   \text{GST} = \text{Pre-tax amount} \times 0.05
   ]
   Example: $100 × 5% = $5.00
4. Total with Taxes:
   [
   \text{Total} = \text{Pre-tax amount} + \text{QST} + \text{GST}
   ]
   Example: $100 + $9.98 + $5.00 = $114.98

Shortcut (Combined Tax):

If you want to calculate the total including both QST + GST (14.975%):
[
\text{Total} = \text{Pre-tax amount} \times 1.14975
]
Example: $100 × 1.14975 = $114.98

3. How to Calculate QST & GST Manually

Method 1: Separate Calculation (QST & GST)

1. Start with the pre-tax price (e.g., $100).
2. Calculate GST (5%):
   [
   \text{GST} = \$100 \times 0.05 = \$5.00
   ]
3. Calculate QST (9.975%):
   [
   \text{QST} = \$100 \times 0.09975 = \$9.98
   ]
4. Add them together:
   [
   \text{Total Tax} = \$5.00 + \$9.98 = \$14.98
   ]
5. Final Price:
   [
   \$100 + \$14.98 = \textbf{\$114.98}
   ]

Method 2: Combined Tax Calculation (14.975%)

For a faster calculation, multiply by 1.14975:
[
\text{Final Price} = \$100 \times 1.14975 = \textbf{\$114.98}
]
