What TaxJar is

TaxJar is sales tax software for calculating tax, registering for tax, and filing returns. It supports automated return filing and API access, and is listed for API use. Founded in 2013, TaxJar has paid plans starting at $39/mo, with a 30-day trial and no free plan. Starter costs $39 a month at the 200-orders-per-month tier and includes three data import integrations and two AutoFile credits per year. Professional costs $99 a month at the same order tier, with ten total integrations, 10,000 API calls per minute, and four AutoFile credits per year. Both plans list the same monthly order tier, while Professional provides larger integration, API-call, and AutoFile allowances. TaxJar suits organizations that need sales tax calculation, registration, and automated filing in an API-based workflow.
