FAQ

How the tax calculation behaves

  • 01

    Can the AI change my tax bracket?

    No. The AI only reads the parameters and performs math based on the data it retrieves.

  • 02

    Does the AI handle my actual tax filings?

    No. The AI calculates the amount due, but it cannot submit documents to government portals.

  • 03

    What happens if my revenue changes?

    You simply provide the new revenue number in your next prompt, and the AI recalculates everything.

  • 04

    Can the AI delete my previous tax records?

    No. This MCP only performs calculations and does not have the ability to delete or modify your external data.

  • 05

    Do I need to provide the tax rates myself?

    No. The AI uses the get_bracket_parameters tool to pull the correct rates automatically.
