FAQ

Questions PIS/COFINS Calculator owners ask.

  • 01

    How do I calculate taxes for the cumulative regime?

    Use the calculate_cumulative_tax capability by providing your total gross revenue. The capability applies a 0.65% rate for PIS and 3% for COFINS.

  • 02

    Can I include input credits in the calculation?

    Yes, when using calculate_non_cumulative_tax, you can provide a JSON array of input costs (like raw materials or energy) to calculate available tax credits.

  • 03

    How does the regime comparison capability work?

    The evaluate_regime_comparison capability calculates both taxation methods simultaneously and recommends the one that results in a lower total tax burden.
