Calculate my PIS/COFINS for 100,000 BRL revenue in the cumulative regime.

The `calculate_cumulative_tax` tool would return a PIS amount of 650.00 and COFINS of 3,000.00, totaling 3,650.00.

Compare regimes for 500,000 BRL revenue with 50,000 BRL in raw material costs.

Using `evaluate_regime_comparison`, the tool will analyze both regimes and suggest the one with the lowest net liability based on your input credits.

What is my tax liability if I have 200,000 BRL revenue and 20,000 BRL in energy costs?

By calling `calculate_non_cumulative_tax` with the provided input credits, you can see your net PIS and COFINS balance.

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