Key Rule: Sales tax is computed after applying discounts to ensure consumers only pay tax on the net transactional amount.

A sales tax is a consumption tax levied by municipal, state, or federal governments on the sale of goods and services. Understanding pre-tax retail margins, trade discounts, and local tax rates enables consumers and small business owners to compute exact cash-register totals.

1. Step-by-Step Sales Tax Equations

\text{Net Price} = \text{Original Price} \times (1 - d) \quad \text{and} \quad \text{Final Total} = \text{Net Price} \times (1 + t)

Where $d$ is the discount rate (e.g., $0.15$ for 15% off) and $t$ is the combined state and local tax rate (e.g., $0.0825$ for 8.25%).

2. Reverse Sales Tax (Extracting Tax from Grand Total)

To find the pre-tax price when only the tax-inclusive final receipt is known:

\text{Pre-Tax Price} = \frac{\text{Total Receipt Amount}}{1 + \text{Tax Rate}}

Frequently Asked Questions (Sales Tax)

What is the difference between Sales Tax and VAT (Value Added Tax)?

Sales tax is collected once at the final retail point of sale to the end consumer. Value Added Tax (VAT) is collected incrementally at every stage of the manufacturing and distribution supply chain.

Are coupons taxed before or after the discount?

Store discounts and retailer coupons reduce the taxable price before calculating tax. However, manufacturer rebates often require paying tax on the full pre-rebate price in many US states.
