TaxSync

TaxSync is a sales tax automation platform that calculates, files, and remits sales tax across all 50 US states and more than 13,000 tax jurisdictions. It provides real-time tax calculations, nexus monitoring and alerts, automated filing with audit protection, exemption certificate management, and connectors for ecommerce platforms such as Shopify and WooCommerce. A free tier supports nexus monitoring, while paid plans include filing rather than charging separately per state return. The Starter plan begins at $49 per month and covers up to five states and 2,000 orders. TaxSync is designed for growing ecommerce businesses, SaaS companies, and multi-channel sellers that want one system for calculation, compliance monitoring, filing, and remittance.
