What it is for
Shows the tax burden of each regime in the chosen base month, using your revenue, RBT12 and payroll. Helps decide the tax classification (an annual decision).
Para que esta tela existe
Compare Simples × Presumido × Lucro Real side by side with your real numbers (revenue, RBT12, payroll) — tax burden and % of revenue. — this is the role of the "Tax regime simulator" screen within the platform.
Rules
Reading the bases
The simulation uses your real figures, not typed-in values: the month's revenue, the RBT12 (gross revenue for the last 12 months) and the 12-month payroll appear right below the Simulate button, read from operations for the chosen base month. Choose the month, click Simulate and compare the three cards — Simples, Presumido and Lucro Real — each with the total, the burden over revenue and the calculation trail open. The lowest-burden card is highlighted, and Lucro Real is an estimate, as its own badge warns.
Lucro Real é estimativa
The Lucro Real shown here is conservative (PIS/COFINS without credits) and the real IR/CSLL falls on the actual profit. Use it as a starting point with your accountant.
Frequently asked questions
O que são a recomendação e o parecer do Tenkai
After the simulation, the screen can display two readings: the recommendation, an objective summary pointing to the regime with the lowest burden for the base month's numbers, and Tenkai's opinion, generated by AI when the feature is enabled for the company — it comments on the comparison in running text. Both are decision support, not a decision: changing tax regime has its own deadline and eligibility rules, and deserves your accountant's validation before any formal move.
