TaxDelta: Sales Tax Audit

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.
