FAQ

How this task behaves

  • 01

    Can the AI change the tax rates?

    No. The AI only reads the withholding status from the database; it cannot modify tax laws or rates.

  • 02

    Does the AI handle the actual tax filing?

    No. The AI only identifies if withholding is required. You must handle all filings and payments yourself.

  • 03

    What if the city isn't in the database?

    The AI will tell you it cannot find a record for that specific city and will suggest you check with a local professional.

  • 04

    Can I use this for state-level tax questions?

    No. The tool is designed for city-specific service tax withholding and does not provide state-wide data.

  • 05

    Does the AI remember my previous lookups?

    The AI can reference your current chat history, but it does not store your tax data in a permanent database.
