Simples Nacional, Lucro Presumido or Lucro Real: How to Compare Tax Regimes
Understand the eligibility variables for Simples Nacional, Lucro Presumido, and Lucro Real in 2026. Analyze corporate restrictions, global revenue, and the impacts of the transition to IBS and CBS.
The choice between Simples Nacional, Lucro Presumido, or Lucro Real in November 2026 requires a technical analysis of annual gross revenue, corporate structure, and operating margins. This decision should not be based on sectoral generalizations, but rather on the current legal framework and cash flow projections considering the tax coexistence between the current system and the new dual VAT model (IBS and CBS). This publication is for informational purposes only and does not constitute individualized legal or accounting advice.
Eligibility Criteria and Restrictions of Simples Nacional
Simples Nacional is a simplified regime intended for Micro-Enterprises (ME) and Small Business Entities (EPP - Empresas de Pequeno Porte), but access is subject to strict criteria. According to Supplementary Law 123 (Lei Complementar 123), specifically in Article 3, §4, eligibility is prohibited for legal entities that have another legal entity as a partner or that participate in the capital of another company.
The analysis of the annual revenue limit must also consider global gross revenue. If a partner of an ME or EPP holds a stake exceeding 10% in another company that is not an optant of Simples Nacional, the sum of the gross revenues of both cannot exceed the legal limit established for the regime. Additionally, Article 17 of LC 123 details activities and situations, such as partners residing abroad or debts with public entities, that prevent the option. Compliance must be verified before any tax simulation, as non-compliance can generate retroactive exclusion from the regime.
Lucro Presumido: Presumption Margin and Limits
In the Lucro Presumido (Presumed Profit) regime, the calculation basis for IRPJ (Corporate Income Tax) and CSLL (Social Contribution on Net Profit) is determined by applying presumption percentages to the gross revenue, according to the activity performed. It is an option available for companies not obliged to Lucro Real and whose annual revenue did not exceed R$ 78 million in the previous calendar year.
A critical decision point in 2026 is the rigidity of the presumed base. Unlike Lucro Real, the presumed regime does not allow for the offsetting of tax losses. Thus, if the company's actual profit margin is lower than the margin presumed by legislation (which varies, for example, from 8% to 32% for IRPJ depending on the activity), the tax burden on income may be proportionally higher than in the net profit calculation regime. The tax effectiveness of this regime is conditional and depends on the stability of operating margins compared to the legal percentages.
Lucro Real: Mandatory Requirement and Calculation
Lucro Real (Actual Profit) is the general rule regime in which the tax is calculated on the accounting net profit, adjusted by additions and exclusions provided for in the tax legislation. According to Articles 13 and 14 of Law 9.718, this regime is mandatory for companies with revenue exceeding R$ 78 million in the previous calendar year. The mandatory requirement also extends to specific sectors, such as financial institutions and companies that earn profits and capital gains from abroad.
The 2026 tax transition introduces additional complexity: the utilization of accumulated PIS and Cofins credits is not transferred to the CBS (Contribution on Goods and Services) framework automatically or identically. Companies in Lucro Real operating with reduced margins may find in this regime a way to adjust the tax burden to financial reality, but this requires rigorous accounting compliance to avoid the disallowance of deductible expenses. For international operation scenarios, it is recommended to consult Lucro Real for importers: when to compare with Lucro Presumido.
Impacts of the Tax Reform: IBS and CBS in 2026
In 2026, CBS and IBS (Tax on Goods and Services) are in the testing and adaptation phase, with collection waivers conditioned on the applicable obligations and hypotheses. This phase should not be interpreted as full collection or automatically usable credit. Simples options for the regular IBS/CBS regime must respect their own calendar and the production of effects in 2027. The choice of Lucro Real or Presumido for IRPJ/CSLL must be evaluated separately from the consumption credit rules.
Decision Factors: Structure and Margin
When comparing regimes, the analysis should be divided into three pillars: legal (eligibility), financial (actual vs. presumed margin), and commercial (tax credits). A service provider company with few deductible costs may, in theory, have a lower burden in Presumido, but if its actual margin falls below the 32% IRPJ presumption, it may be useful to simulate Lucro Real, without concluding that migration is mandatory or economically superior based on that indicator alone.
The sum of global revenue in economic groups is one of the most common errors. LC 123 provides for distinct hypotheses of global revenue; common partners do not authorize an unrestricted consolidation of all direct and indirect holdings. Details on the calculation of limits for groups can be found in Related companies in Real, Presumido and Simples: limits and risks. The deadlines and acts of option vary according to the regime and the situation; there is no universal January deadline, especially for options with effects in 2027.

FAQ - Frequently Asked Questions
Is Lucro Real always better for those with low margins?
Not necessarily. Although it allows for taxation on actual profit, Lucro Real requires higher costs for accounting compliance and auditing. Viability depends on the balance between tax savings and the increase in administrative costs.
How does global gross revenue affect the Simples Nacional limit?
If a partner participates in more than one company, the sum of the revenues of all of them cannot exceed the annual ceiling of LC 123, provided that the stake is greater than 10% and one of them is not in Simples, or at any percentage if both are in Simples.
Will IBS and CBS replace PIS and Cofins immediately?
In 2026, the transition begins with reduced rates of IBS and CBS, coexisting with current taxes. The complete replacement is gradual and requires attention to the transition rules of LC 214/2025.
Conclusion and Next Steps
The definition of the tax regime in 2026 must be preceded by an eligibility audit and a simulation based on real business data. Changes in cost structure or the customer base can invalidate the previous year's choice. Periodic review of ancillary obligations and monitoring of Federal Revenue (Receita Federal) regulations are recommended. For specific support in the dual VAT transition, consult qualified professionals.
