Frequently Asked Questions
How do I calculate the original price before tax?
Divide the total price by (1 + tax rate as decimal). Example: If you paid $108.75 with 8.75% tax, the pre-tax price = $108.75 ÷ 1.0875 = $100. The tax amount = $108.75 - $100 = $8.75.
Why would I need to find the price before tax?
Common reasons include: expense reporting for business reimbursements (company reimburses pre-tax amount), comparing prices across different tax jurisdictions, VAT reclaim for international business travel, and accounting journal entries.
