Simples Nacional vs Lucro Presumido vs Lucro Real Compared

Simples Nacional vs Lucro Presumido vs Lucro Real: Which Is Right for Your Business?

The right tax regime for your Brazilian SMB depends on three variables: your annual gross revenue, your profit margins, and your specific business activity. There is no universally best option — a service company with 40% margins and R$3M in revenue faces a completely different calculus than a distributor with 8% margins and R$15M in revenue. This guide provides the framework to make the right choice, with specific numbers and scenarios.

Choosing the wrong tax regime is one of the most expensive mistakes a Brazilian SMB can make. We have seen companies overpay by R$100,000-R$500,000 annually simply because they never revisited a decision made when the business was much smaller. Since regime changes can only happen in January, the cost of inaction compounds year after year. Learn more about our operational excellence services.

The Three Regimes at a Glance

Simples Nacional

What it is: A simplified, unified tax regime for micro and small businesses created by Complementary Law 123/2006. It consolidates up to eight federal, state, and municipal taxes into a single monthly payment (DAS).

Revenue limit: R$4.8 million annual gross revenue (R$400,000/month average).

Key advantage: Administrative simplicity. One payment, one due date (20th of the following month), reduced compliance burden.

Key disadvantage: At higher revenue ranges, effective rates can exceed Lucro Presumido, especially for service companies in Annexes III, IV, and V.

Lucro Presumido

What it is: A tax regime where the government presumes your profit margin based on your activity type, then taxes that presumed profit. You do not need to prove actual profit.

Revenue limit: R$78 million annual gross revenue.

Key advantage: Predictability. Your tax burden is a function of revenue, not actual profit, making it advantageous for high-margin businesses.

Key disadvantage: If your actual margins are lower than the presumed margins, you overpay. PIS/COFINS is cumulative (no credits), typically at 3.65% combined.

Lucro Real

What it is: The regime where you are taxed on your actual accounting profit, with full deductibility of legitimate business expenses.

Revenue limit: Mandatory for companies with revenue above R$78 million. Optional for any company.

Key advantage: You only pay tax on actual profit. Full PIS/COFINS non-cumulative credits (9.25% rate but with credits on inputs). Essential for low-margin businesses.

Key disadvantage: Highest compliance burden. Requires impeccable bookkeeping, SPED ECD/ECF compliance, and careful management of deductible vs. non-deductible expenses.

Effective Tax Rates by Revenue Range

This is where the decision gets concrete. Here are approximate effective tax rates for a service company (consulting, technology, professional services):

Service Company — Annex III (Effective Rates)

Annual Revenue	Simples Nacional	Lucro Presumido	Lucro Real (20% margin)
R$500,000	~6.0%	~13.3%	~16.0%
R$1,000,000	~8.2%	~13.3%	~16.0%
R$2,000,000	~11.5%	~13.3%	~16.0%
R$3,000,000	~14.0%	~13.3%	~16.0%
R$4,000,000	~16.0%	~13.3%	~16.0%

Crossover point: Around R$2.5M-R$3M for Annex III service companies, Lucro Presumido often becomes more tax-efficient than Simples Nacional.

Service Company — Annex V (Higher Rates, Factor R Dependent)

Companies in Annex V face higher Simples rates (starting at 15.5%) but can migrate to Annex III rates if their payroll-to-revenue ratio (Fator R) exceeds 28%. This means:

High payroll businesses (Fator R > 28%): Annex III rates apply — Simples remains competitive longer
Low payroll businesses (Fator R < 28%): Annex V rates apply — transition to Lucro Presumido is often advantageous at R$1.5M-R$2M

Commerce and Industry

For retail, wholesale, and manufacturing (Annexes I and II), Simples Nacional is generally competitive up to R$3.5M-R$4.5M because the starting rates are lower (4% for commerce, 4.5% for industry) and ICMS is included.

However, companies that purchase significant inputs should model Lucro Real carefully. The non-cumulative PIS/COFINS regime allows credit recovery on purchases, which can dramatically reduce the effective tax burden for businesses with high cost of goods.

When to Switch: Decision Framework

Trigger 1: Revenue Approaching R$4.8M

If your trailing 12-month revenue is approaching R$4.8M, you must plan for the transition. Exceeding the limit mid-year results in retroactive exclusion from Simples, with tax recalculation from January. This can create a significant unexpected tax liability.

Action: Begin modeling Lucro Presumido and Lucro Real scenarios in Q3, make your decision by October, and file the exclusion from Simples by December 31 (or it happens automatically when you exceed the limit).

Trigger 2: Effective Rate Comparison

Run this analysis annually:

Calculate your actual Simples Nacional rate (total DAS paid / gross revenue)
Model your Lucro Presumido burden (IRPJ + CSLL on presumed profit + PIS/COFINS at 3.65% + ISS/ICMS separately + CPP at 20% of payroll)
Model your Lucro Real burden (IRPJ + CSLL on actual profit + PIS/COFINS at 9.25% with credits + ISS/ICMS + CPP)
Compare all three, including the additional compliance cost of each regime

Trigger 3: Low Fator R (Service Companies)

If you are in Annex V and your Fator R has dropped below 28% (common as revenue grows faster than headcount), your effective Simples rate may be 18-20%. At these rates, Lucro Presumido is almost certainly cheaper.

Trigger 4: High Input Costs

If your COGS or input costs represent more than 40-50% of revenue, Lucro Real with non-cumulative PIS/COFINS credits deserves serious modeling. A distributor with 60% COGS effectively pays PIS/COFINS on 40% of revenue (the value added), not 100%.

Transition Planning: A Practical Checklist

Switching tax regimes is not just a tax decision — it impacts your entire operation. Here is what to prepare:

Financial Preparation

Model the new regime for at least 3 months of actual data before committing
Build the additional compliance cost into your budget (Lucro Real typically adds R$2,000-R$8,000/month in accounting fees)
Adjust cash flow forecasts for new tax payment timing (quarterly IRPJ/CSLL vs. monthly DAS)
Review pricing to ensure margins remain viable under the new tax structure

Operational Preparation

Ensure your ERP/accounting system supports the new regime
Train your finance team on new reporting requirements
For Lucro Real: implement rigorous expense documentation (every deduction must be substantiated)
For non-Simples regimes: set up separate ISS/ICMS compliance processes

Compliance Preparation

Confirm your accounting firm has expertise in the target regime
Understand SPED obligations (ECD, ECF for Lucro Real; EFD-Contribuicoes for both Presumido and Real)
Review employee benefits structure (CPP moves from DAS to separate calculation)
File the regime change with the Receita Federal by January 31 (but ideally by December 31 of the prior year)

Real-World Scenarios

Scenario 1: IT Consulting Firm, R$3.5M Revenue, 35% Net Margin

Simples (Annex V, Fator R = 22%): ~18% effective rate = R$630,000 in taxes
Lucro Presumido: ~13.3% effective rate = R$465,500 in taxes
Savings from switching: R$164,500/year

This firm should have switched to Lucro Presumido at least a year ago. The additional accounting cost of R$3,000-R$5,000/month is trivially offset by the savings.

Scenario 2: E-commerce Distributor, R$12M Revenue, 6% Net Margin

Lucro Presumido (8% presumed margin for commerce): Pays tax on R$960,000 presumed profit even though actual profit is R$720,000
Lucro Real: Pays tax on R$720,000 actual profit, plus recovers PIS/COFINS credits on R$9M in purchases
Savings from Lucro Real: R$80,000-R$150,000/year depending on creditable inputs

For low-margin, high-volume businesses, Lucro Real is almost always the right answer.

Scenario 3: Marketing Agency, R$2M Revenue, 30% Net Margin, Fator R = 35%

Simples (Annex III, due to high Fator R): ~11.5% effective rate = R$230,000
Lucro Presumido: ~16% effective rate = R$320,000
Recommendation: Stay on Simples. The high Fator R keeps rates in Annex III, and the simplicity benefit is worth the marginal difference.

Common Mistakes to Avoid

Staying on Simples out of inertia: “We have always been on Simples” is not a financial strategy. Review annually.
Ignoring payroll impacts: When you leave Simples, CPP (20% employer contribution) becomes a separate line item. Factor this into your comparison.
Underestimating Lucro Real compliance: The tax savings are real, but so are the compliance costs. Budget R$3,000-R$10,000/month in additional accounting fees and invest in documentation processes.
Forgetting about ISS/ICMS: Under Simples, these are included in the DAS. Under other regimes, they are separate obligations with their own rates, due dates, and compliance requirements.
Not planning the transition timeline: Changes happen in January. If you realize in March that you should have switched, you wait until next January. Start planning in Q3.

The Strategic Perspective

Tax regime optimization is a component of your broader financial strategy. The best regime today may not be the best regime in two years as your business grows. Build an annual tax review into your financial calendar, ideally in September-October, so you have time to model scenarios and implement changes before the January deadline.

For companies in the R$2M-R$50M range, the difference between the right and wrong regime is typically 2-5% of revenue. On R$10M in revenue, that is R$200,000-R$500,000 — enough to fund a key hire, a marketing campaign, or a technology investment.
