Three tools dominate the US sales tax automation market: TaxJar (now owned by Stripe), Avalara (public enterprise player), and Stripe Tax (native to Stripe's payment stack). Each wins in a specific scenario. Here's a practical breakdown for sellers evaluating them in 2026.
TL;DR by business type
- Solo Shopify store under $500K revenue: TaxJar (starter plan, low lift).
- Shopify/WooCommerce store $500K-$5M, multi-channel: TaxJar (pro plan) or Avalara Returns (if you need filing automation).
- Enterprise retailer $10M+, complex exemptions: Avalara (customer-certificate automation, ERP integrations).
- SaaS on Stripe: Stripe Tax (zero-friction activation).
- Multi-country (US + EU VAT): Avalara or Quaderno.
Pricing comparison
| Tool | Starting price | Pricing model |
|---|---|---|
| TaxJar | $19/mo Starter | Tiered by transactions/mo |
| Avalara | ~$500/mo (SMB plan) | Custom quote, transactions + features |
| Stripe Tax | $0 upfront, 0.5% of taxable tx | Pay-as-you-go, Stripe-only |
Integrations
TaxJar: Shopify, WooCommerce, BigCommerce, Amazon, Walmart, Etsy, Square, Stripe, QuickBooks, NetSuite.
Avalara: 1,200+ pre-built connectors including every major ERP (NetSuite, SAP, Dynamics, Oracle), full Shopify/Magento coverage, exemption certificate management, and VAT.
Stripe Tax: Stripe only. If you're not using Stripe for payments, this isn't an option.
What about filing?
TaxJar and Avalara both file returns for you (AutoFile / Returns). Stripe Tax does NOT file — it only calculates and collects. You still need a separate filing solution or accountant.
Bottom line
Most Shopify + Amazon sellers under $10M annual revenue: TaxJar. Enterprise with ERP + exemption certificates: Avalara. Pure SaaS on Stripe: Stripe Tax plus an external filing partner (TaxValet is popular for this).
