TaxJar

TaxJar automates US sales tax compliance for businesses selling across multiple states. It calculates the correct tax rate at the point of sale using real-time data across all 50 states and more than 11,000 jurisdictions, then keeps reports up to date so your firm or client can see exactly what is owed by state, county, and city.

The AutoFile service handles return preparation and submission on the correct deadline. TaxJar reports a 100 percent on-time filing rate and files millions of returns per year. Nexus Insights tracks economic nexus thresholds so firms advising multi-state sellers know when a new state registration is needed before the client crosses the line.

TaxJar works with Amazon, Shopify, WooCommerce, QuickBooks, and a range of other platforms via API. Accounting firms can connect client accounts to pull order data, review reports, and manage AutoFile credits across multiple clients from one login.

Pricing starts at $39 per month on the Starter plan, which covers up to 200 orders and includes 2 AutoFile credits per year. The Professional plan at $99 per month adds phone support, a Customer Success Manager, historical archive access, and 4 AutoFile credits. Annual billing saves 10 percent or more. A 30-day free trial with full Professional plan access and no credit card required is available. TaxJar covers US jurisdictions only.
