The bottom line

APIVerve or TaxJar?

TaxJar and APIVerve answer different questions.

Use APIVerve if

  • You need a rate for a quote, cart, invoice or internal tool
  • You want to try it free, with no nexus setup
  • You want EU VAT rates or MCP tools on the same key

Use TaxJar if

  • You have nexus in several states
  • You need returns filed and remitted for you
  • You rely on product tax codes and exemptions
Read the full verdict

TaxJar is a compliance product: it works out what you owe on each order from street addresses, shipping, product tax codes, nexus and exemptions, then files and remits the returns, and Stripe now owns it. If you have nexus in several states and need returns filed, that is what to pay for. APIVerve is a rate lookup.

Send a ZIP and get the combined rate, or send an amount and get the tax and the total, with the state, county, city and district split on paid plans. It starts free, has no nexus setup, works as an MCP tool, and EU VAT rates come on the same key. Rates are ZIP-level estimates and nothing gets filed for you, so it fits quotes, carts, invoices and internal tools better than end-to-end compliance.

TaxJar questions.

Common questions about switching from TaxJar to APIVerve.

Talk to us →
Is APIVerve a free TaxJar alternative?
To try rate lookups and simple tax calculation, yes. APIVerve's Free plan returns the combined sales tax rate for a ZIP or a state, and the tax amount and total for an order, each month at no cost; it is meant for evaluation, and production use starts on the $12.99/mo Hobby plan. TaxJar has no free plan; it offers a 30-day trial, and its API comes with the Professional plan at $99/mo. APIVerve does not file returns or track nexus, which TaxJar does.
Can I still sign up for TaxJar now that Stripe owns it?
Yes. Stripe acquired TaxJar in 2021, and TaxJar's pricing page still offers a 30-day trial and Starter and Professional plans. It also suggests Stripe Tax if you already take payments through Stripe, and its API docs point to Stripe Tax for calculations outside the US.
How much does the TaxJar API cost?
TaxJar's pricing page lists Starter at $39/mo with API access marked N/A, and Professional at $99/mo with API access, a developer sandbox and up to 10,000 calls a minute, both at 200 orders a month. Each rate lookup or calculation counts as a transaction toward the plan limit. APIVerve's Starter plan is $29.99/mo and covers the sales tax APIs along with the rest of the catalog.
Does APIVerve return state, county, city and district rates like TaxJar?
Yes, on paid plans. A ZIP lookup returns the combined rate plus its state, county, city and special district parts and the region name, and the calculator also returns each part's share of the tax in dollars. The Free plan returns the combined rate.
Is APIVerve as accurate as TaxJar or Avalara AvaTax?
It works at a different level. APIVerve rates are ZIP-level estimates, so an address near a city or district line can owe a slightly different rate. TaxJar can rate a full street address, which its docs call rooftop accuracy, and Avalara AvaTax covers tax rates and rules for 200+ countries and jurisdictions. If you need address-level accuracy, product taxability or filing, use one of them. If you need a rate by ZIP that is free to start, APIVerve covers it.
How do I switch from the TaxJar rates endpoint?
Replace GET /v2/rates/:zip with a call to APIVerve's Sales Tax Lookup with zip=, and read rate for the combined rate (TaxJar's combined_rate). On paid plans, stateRate, county, city and special map to state_rate, county_rate, city_rate and combined_district_rate. For order totals, call the Sales Tax Calculator with amount and zip.
