Frequently asked questions
How do I add sales tax?
Multiply price × rate and add it. 8% on $100 = $8, total $108 (or price × 1.08).
How do I remove sales tax?
Divide the total by 1 + rate. $108 ÷ 1.08 = $100 pre-tax; tax was $8.
Sales tax vs VAT?
Both are consumption taxes on price; VAT is collected in stages, sales tax once at final sale. The single-rate math is identical.
