Simples Nacional or Presumed Profit? See the comparison

Choose between Simples Nacional or Presumed Profit It is one of the most important tax decisions any company can make.

An inappropriate tax structure can increase the tax burden, compromise cash flow, and reduce the business’s competitiveness. On the other hand, a decision based on a comprehensive tax assessment can result in annual savings of tens or even hundreds of thousands of reais.

That decision became even more strategic in 2026. With the changes brought about by Tax reform and the start of the implementation of the Dual VAT (CBS and IBS), many companies have begun to reassess their tax structures.

In this comprehensive guide, you’ll learn about the main differences between Simples Nacional and Lucro Presumido, how taxation works under each system, what factors to consider before switching, and in which situations it’s worth changing tax systems.

What is Simples Nacional?

O Simples Nacional It is a tax system designed to simplify tax collection from micro and small businesses. Under this system, various federal, state, and municipal taxes are paid using a single payment form, known as DAS (Simples Nacional Collection Document).

Companies with annual gross revenue of up to R$ 4.8 million, provided they meet the other requirements set forth in the law.

Taxes typically included in the DAS include:

• IRPJ;
• CSLL;
• PIS;
• Cofins;
• IPI (when applicable);
• CPP (except for companies listed in Annex IV);
• ICMS;

The main advantage of Simples Nacional is precisely its operational simplicity. In addition to consolidating tax payments, the system reduces ancillary obligations compared to other tax systems.

However, simplicity does not necessarily mean a lower tax burden. This is one of the biggest misconceptions found in companies.

Many business owners remain in the Simples Nacional program for years without realizing that another tax regime could offer much greater savings.

How does the Simples Nacional tax system work?

Contrary to what many people think, the Simples Nacional There is no single tax rate. Taxation depends on several factors:

• Occupation;
• Tax Schedule;
• Total revenue for the past twelve months;
• R Factor (for certain activities).

Today, the system is divided into five schedules, each with its own revenue brackets and tax rates.

That's why two companies with the same revenue They may collect their taxes at completely different rates.

A technology company, for example, may be taxed under Annex III or Annex V, depending on the R Factor. A construction company, on the other hand, will be subject to Annex IV.

This complexity shows that Simples Nacional is no longer a “simple” system from a strategic standpoint.

Annex I – Trade

Annex II – Industry

Annex III – Services

Annex V – Services

That said, we need to clarify that considering the values in the "Deductible amount", The maximum effective Simples Nacional tax rate is 19.50% on monthly turnover.

What is Presumed Profit?

O Presumed Profit It is a tax system in which the law presumes a profit margin on the company's revenue to calculate part of its federal taxes.

Instead of calculating the actual profit earned, the law establishes presumptive percentages based on the type of economic activity.

These percentages serve as the basis for calculating:

• IRPJ;
• CSLL.

However, taxes such as:

• PIS;
• Cofins;
• ISS;
• ICMS (when applicable)

They continue to be calculated according to their own rules.

The Presumed Profit method is commonly used by service providers, medical clinics, consulting firms, holding companies, technology companies, and various medium-sized businesses.

Although it is more complex to administer than Simples Nacional, It also offers significant tax planning opportunities.

How does Presumed Profit taxation work?

One of the main differences lies precisely in how taxes are calculated. While under the Simples Nacional system virtually all taxes are paid on a single payment slip, under the Presumed Profit system each tax has its own method of calculation.

The main taxes are:

• IRPJ;
• CSLL;
• PIS;
• Cofins;
• ISS;
• ICMS (when applicable);
• Payroll tax.

This separation requires more robust accounting and tax controls. On the other hand, it allows for a tax planning much more flexible.

Depending on the company's structure, this flexibility can result in significant savings.

IRPJ

In Presumed Profit, we need to multiply one of the rates below by the 15% rate of IRPJto arrive at the percentage that will be applied to turnover to calculate the tax due.

Thus, a company that sells goods will pay 8% x 15% = 1.20% of IRPJ on turnover.

CSLL

In turn, to calculate the CSLLIn order to calculate the tax due, we need to multiply one of the rates below by the 9% rate, and only then arrive at the percentage that will be applied to the turnover to calculate the tax due.

Therefore, a company that sells goods will pay 12% x 9% = 1.08% of CSLL on turnover.

PIS and COFINS

In the case of PIS and COFINS, In this case, we should use the following calculation rates on turnover:

• PIS: 0.65% on turnover;
• COFINS: 3% on turnover.

ICMS and ISS

Finally, the ICMS and ISS are calculated based on the rates and what is determined by state legislation (in the case of ICMS) and municipal legislation (in the case of ISS).

Having made this comparison, the question remains: when should you migrate from Simples Nacional to Lucro Presumido? The answer is in the next article.

Comparison: Simples Nacional vs. Presumed Profit

In Simples Nacional, taxation is based on an effective tax rate calculated according to the company’s cumulative revenue over the past 12 months and the tax bracket to which the company belongs.

In Presumed Profit, each tax is calculated separately. The final percentage depends on the type of business activity, the municipality (ISS), the ICMS tax rate when applicable, and the payroll.

Here's a simplified comparison:

This table shows that the decision should not be based solely on operational convenience. Growing companies typically need to evaluate much broader factors.

In many cases, companies remain in the Simples tax regime simply because they have never filed a comprehensive tax assessment.

Over the years, revenue grows, the operational structure changes, the customer base evolves, and the tax regime ceases to be the most efficient. Even so, no review is conducted.

The result is often a higher tax burden than necessary. It is precisely at this point that a Technical analysis starts to make a difference.

Simples Nacional or Presumed Profit: A Comparison by Business Type

So far, it has become clear that there is no single tax system that is universally better. The choice depends on the characteristics of the company.

With that in mind, let's analyze how this decision impacts different segments and what criteria a CFO you should consider before choosing between Simples Nacional and Presumed Profit.

Technology Companies: Is Simples Nacional Still the Best Option?

Startups, software companies, systems development firms, IT consulting firms, SaaS solution providers, and cybersecurity companies They usually start out under the Simples Nacional system because of its simplicity and, in many cases, the reduced tax burden.

However, as these companies grow, the landscape changes.

Imagine a software company that had annual revenue of R$ 800 mil and, after winning new contracts, began generating annual revenue of R$ 4 milhões.

In addition to the increase in the effective tax rate under the Simples Nacional system, other factors now directly influence the decision, such as:

• Payroll growth;
• Composition of the customer base;
• Contracts with large companies;
• The need to use tax credits;
• Expansion into other states;
• Corporate planning.

It is common for technology companies to serve large corporate clients. In such cases, tax considerations no longer affect only the service provider but also have an impact on the client.

With the gradual implementation of the Tax reform, this analysis has become even more relevant.

Companies under the Presumed Profit regime may offer greater tax efficiency in B2B transactions, especially when their customers value the use of credits.

However, this does not mean that every technology company should make the switch. It simply means that the decision is no longer based solely on the tax burden on revenue.

Today, commercial competitiveness is also part of the equation.

Consulting and specialized services firms

Business consulting firms, engineering firms, design firms, marketing agencies, financial advisory firms, and various service providers face a similar situation.

When starting a business, staying in the Simples Nacional program is usually a natural choice.

However, as the business matures, there are some signs that indicate it is worth reviewing the framework:

• Rapid revenue growth;
• Increase in average transaction value;
• Predominance of corporate clients;
• National expansion;
• The need for stronger financial governance.

In Presumed Profit, the company can forecast its tax burden with greater stability, making financial planning and the preparation of the annual budget easier.

For CFOs, this predictability represents a significant advantage.

Commerce and Industry

Although Simples Nacional While it remains highly competitive for many commercial companies, the analysis should also take into account factors such as:

• Gross margin;
• Tax substitution;
• State tax benefits;
• Purchase volume;
• Supply chain.

Industrial companies face an even more complex landscape. In addition to federal taxation, factors such as the ICMS, regional incentives, tax credits, and supply chain planning come into play.

In many cases, remaining in the Simples Nacional program means forgoing credit recovery mechanisms that could reduce the tax cost of the transaction.

However, once again, there is no ready-made answer. There is a need to expert analysis.

When Is It Worth Switching from Simples Nacional to Presumed Profit?

The transition between systems should not occur simply because the company has grown. It should be the result of a technical study. In the CLM Controller, certain factors often set off alarm bells:

Revenue growth: Companies approaching the R$ limit of 4.8 million typically need to begin this assessment even before reaching the cap.

Waiting for the mandatory reclassification may prevent proper planning. In addition, the company misses the opportunity to compare scenarios in advance.

Primarily B2B customers: When virtually all revenue comes from other companies, the choice of tax regime can directly affect business competitiveness.

Depending on the clients' profile, a structure that allows for the most effective use of tax credits can provide an advantage in negotiations.

This aspect has become even more important with the gradual implementation of the Tax reform.

Planning for Investment Attraction: Startups and scale-ups looking to raise funds often invest in professionalizing their financial controls.

Although the tax system is not, on its own, a determining factor in an investment round, it does influence:

• Accounting organization;
• Financial predictability;
• Transparency of the financial statements;
• Quality of management information.

These factors boost the confidence of investors and financial institutions.

How to migrate from Simples Nacional to Lucro Presumido?

When the strategic decision to change regime has been made, a new doubt arises: how to migrate from Simples Nacional to Lucro Presumido safely, without compromising the company's financial and fiscal health?

See below for a complete step-by-step guide to making the move safely:

1. Carry out a detailed tax analysis

The first step is to understand whether the switch really makes sense for your company. That's why it's essential to compare the effective tax burden of Simples Nacional with that of Lucro Presumidoconsidering:

• Monthly and annual turnover
• Operation profit margin
• Type of activity
• Incidence of taxes such as ICMS or ISS
• Whether or not tax credits can be used

Realistic simulations based on actual company data are indispensable. With this in mind, specialized accountants can use advanced tools and spreadsheets to calculate the monthly and annual tax in both regimes, enabling a technically based decision.

2. Request removal from Simples Nacional

Having confirmed that migrating to Presumed Profit is advantageous, it's time to formalize the withdrawal from Simples Nacional. This process must be done:

• Through the Simples Nacional portal, accessing with the company's digital certificate
• Until the last working day of January of the calendar year in which you wish to adopt the new regime
• With the knowledge that, once done, the disqualification is irreversible for that year

• The company may need to configure different CFOPs (Tax Codes for Transactions and Services)

5. Establish a routine for continuous accounting monitoring

Unlike Simples, where monthly calculation is relatively simple, Lucro Presumido requires greater control over ancillary obligations, such as:

• EFD Contributions (PIS and COFINS Sped)
