TaxDelta audits the sales tax you already collected. Standard scans your full order history, and the free plan checks your last 60 days. It flags tax over-refunded on partial refunds, exempt orders charged tax, tax below the state rate, and tax collected in states where you aren't registered. Each finding shows the order, amount, and severity. It also lists exempt and non-USD orders tax filing software often reports wrong. TaxDelta doesn't file returns or see what your filing software reports.

• Detects tax overpayment from partial refunds across all jurisdictions
• Flags undercollection when collected rates fall below state base rates
• Identifies tax collection in states where you're not registered
• Flags exempt orders that were charged tax or need a filing check
• Export findings as CSV for your accountant or tax advisor
