FAQ

Common questions

  • 01

    Can the AI file my taxes automatically?

    No. The AI only performs simulations and comparisons to help you decide which regime to use. You must handle the actual filing through your accountant or tax software.

  • 02

    Does the AI update itself when tax laws change?

    The AI uses the logic provided by the connector. It does not monitor real-time legislative changes in Brazil automatically.

  • 03

    What data do I need to provide?

    You need to provide your annual revenue and your profit margin to get an accurate comparison.

  • 04

    Can the AI change my tax regime in the government system?

    No. The AI has no access to government portals or official tax registration systems.

  • 05

    Can I use this for companies with very low revenue?

    Yes, though Simples Nacional is usually the default for smaller businesses, the AI will still run the math for all three to confirm.
