A broad tax engine for businesses managing high-volume, multi-jurisdiction transactions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Avalara AvaTax is a cloud-based tax determination engine for businesses calculating taxes across sales and purchasing workflows. It supports sales and consumer use tax, VAT, communications tax, occupancy and lodging tax, and excise tax. The product is suited to organizations handling high transaction volumes across multiple jurisdictions, with web and API access for operational and system-based workflows.
Its feature set covers the core compliance workflow: real-time calculation, address validation, jurisdiction mapping, product taxability codes, custom transaction rules, nexus tracking, exemption certificate validation, reporting, and audit trails. The REST API supports tax calculation and address validation, while integrations connect AvaTax with platforms including Shopify, NetSuite, QuickBooks, Sage, Microsoft Dynamics 365, SAP, Adobe Commerce, BigCommerce, WooCommerce, Salesforce, Oracle, Stripe, and Zuora. That breadth makes it a strong fit for businesses coordinating tax logic across ecommerce, ERP, accounting, procurement, and point-of-sale systems.
According to the published plans, Core Compliance costs $79 per state per month or $799 per state per year and includes real-time calculation, Managed Returns filing and remittance, compliance support, business system integrations, nexus monitoring across all 50 states, and AvaTax Exemptions. Core Compliance + SST Services costs $69 per state per month or $699 per state per year, adding qualifying sellers’ no-cost calculation, filing, and remittance in up to 25 states, audit liaison support, and a single SST identification number. Custom adds multi-entity management, consolidated reporting, customized workflows, advanced compliance support, and dedicated support levels. AvaTax is a practical choice for complex, integrated tax operations; organizations seeking a free or simpler standalone tool should look elsewhere.
