Sales Tax Formulas
Add Sales Tax
Total = Amount × (1 + Tax Rate/100)
Tax = Amount × Tax Rate/100
Example: $100 × 1.08 = $108 (Tax $8)
Remove Sales Tax
Pre-Tax = Total ÷ (1 + Tax Rate/100)
Tax = Total - Pre-Tax
Example: $108 ÷ 1.08 = $100 (Tax $8)

Sales Tax Tips

- 💡Use automated tax software: For multi-state businesses, consider sales tax automation tools to reduce compliance risk.
- 💡Watch for tax holidays: Plan major purchases during sales tax holidays to save 5-10% on qualifying items.
- 💡Understand economic nexus: If you sell online, know the thresholds for each state where you have customers ($100,000-$500,000 in sales).
