TaxJar
TaxJar is a cloud-based sales tax compliance platform for U.S. ecommerce businesses, including Amazon sellers, Shopify merchants, and multi-channel retailers. It automates sales tax calculations, nexus tracking, reporting, and filing, with a focus on helping online sellers stay compliant across U.S. state and local jurisdictions.
For Amazon sellers, TaxJar pulls in order data directly from Seller Central and other connected channels, then produces state-by-state reports that match how each jurisdiction expects sales tax to be filed. It fits into the workflow between Amazon payouts and state filings, and is best suited to U.S.-only sellers. International sellers that need VAT or GST support will need a separate solution.

Considerations
- Focuses on U.S. sales tax only and does not support VAT, GST, or other international tax regimes.
- AutoFile credits are limited on each plan, and filings beyond the included credits are billed per return.
- Sellers filing in many states should model AutoFile overage costs when comparing total cost of ownership.
- The Starter plan has lower order volume limits, so higher-volume multi-channel sellers may need to upgrade as they scale.
- Now owned by Stripe, so teams should verify current roadmap and integration coverage for their specific stack.
