Step 2 — Your breakdown
We reverse the tax using the standard formula:
Enter a total and tax rate to see your breakdown.
Employees filing expense reports need pre-tax amounts by category. Resellers on eBay, Amazon, or flea markets need cost net of tax before markup.
Bookkeepers cleaning mixed receipts use reverse math when OCR only captured the grand total.
Removing tax after the fact is mathematically exact when you apply the same combined rate that was charged originally.
If you only know the state, local tax may still be missing—overstating pre-tax price and understating tax extracted.
You paid $108.25 including 8.25% sales tax and need the merchandise amount for bookkeeping.
Pre-tax: $100.00 | Tax: $8.25 | Total: $108.25
Reverse math is for splitting receipts and estimates—it does not replace filing obligations, nexus analysis, or professional tax advice. Confirm rates with your state revenue department or marketplace reports before remitting.
Mathematically yes — accuracy depends on using the correct rate that was applied at purchase.
Mathematically yes. Legally, you still owed the tax at purchase—this tool does not generate refunds.
