FAQ

How this task behaves

  • 01

    Can the AI file my sales tax returns?

    No. The AI identifies nexus and summarizes your data, but it cannot submit tax filings to state authorities.

  • 02

    Does the AI change my TaxJar settings?

    No. The AI only reads data from TaxJar to perform its analysis. It cannot modify your account or settings.

  • 03

    How accurate are the nexus alerts?

    The AI is as accurate as the data provided in TaxJar. It uses the specific thresholds and sales numbers found in your account.

  • 04

    Can I use this with any AI client?

    Yes, as long as your client is MCP-compatible, like Claude, Cursor, or Windsurf.

  • 05

    Will the AI tell me exactly how much tax I owe?

    The AI identifies where you have nexus, but calculating the exact tax amount to pay is a task for a human or a dedicated tax filing tool.
