What is my rate limit for the TaxJar API?
During peak seasons, you may experience increased traffic to your website, which may result in an increase in sales tax calculations/rate lookups or orders pushed into TaxJar.
- Customers on TaxJar Professional subscription plans have a rate limit of 10,000 API calls a minute which includes any call to our API.
If you’re exceeding this rate and encountering 429 errors, we recommend reviewing the following:
- Only make calculation requests in states/regions where you have nexus.
- Cache responses if the order details haven’t changed since the last calculation at checkout.
- Use our summarized rates endpoint as a fallback to ensure sales tax is collected.
If you believe your company may need a higher rate limit, please contact us at email@example.com about upgrading to increase your rate limits.
