TaxJar
Automated sales tax calculations, reporting, and filing
About TaxJar
TaxJar automates the entire sales tax compliance lifecycle for e-commerce businesses and software companies: real-time rate calculations at checkout, multi-state nexus tracking, automated return preparation, and AutoFile for hands-free state filings. Its AI-driven economic nexus alerts notify businesses when they approach thresholds in new states — before they become liable. TaxJar integrates natively with Shopify, WooCommerce, Amazon, and most major e-commerce platforms. Acquired by Stripe in 2021, TaxJar benefits from deep Stripe integration and is embedded in Stripe Tax.
