What can I do if I don't think your rates or tax codes are correct?


You believe a rate or tax code in AvaTax is inaccurate; what are your options?


Avalara AvaTax


  • We have a team of research analysts who maintain the tax rates and tax codes provided by our service:
    • Taxability and tax rates of transactions processed by our service depend on the specific origin and destination address on the sale, the customer's taxable or specific exempt status, what was sold (based on line item tax codes), the tax date, and your unique company settings including nexus selections, company preferences, and tax rules, etc. that were in place at the time when the transaction was processed
    • Though a rate may appear to be incorrect on an individual sale, analysis of the transaction and service settings typically uncover a previously unconsidered component, explaining the tax calculation
  • To challenge a rate or code provided by our service where all settings were as expected, but the rate or taxability was unexpected, submit a case to Avalara Support with any supporting information. 
    • Include specific document codes and dates (where the rate information was incorrect) as examples
    • Include documentation from the jurisdiction which indicates the rate should be different
    • We analyze the transactions and rate in question to ensure we have all needed information, then escalate to our content team for review to verify the rate
