See every featureRefundTaxBack audits refunded orders to estimate when sales tax may have been over-remitted after partial refunds. It compares expected refunded tax with actual refunded tax, groups positive gaps by jurisdiction and filing period, and exports order-level evidence for accountant review. The app is read-only, uses Shopify Billing, and labels recovery values as estimates.
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.
