Lucro Real (Actual Profit) is Brazil’s most detailed tax regime. Taxes are calculated on the company’s real accounting profit, adjusted by additions and exclusions defined in tax law. It demands rigorous bookkeeping but can result in significantly lower taxes for companies with thin profit margins or high deductible expenses.

How Lucro Real Works

Unlike Lucro Presumido, which assumes a fixed profit margin, Lucro Real uses your company’s actual financial results. The accounting profit from your income statement is adjusted through the LALUR (Livro de Apuração do Lucro Real) to arrive at the taxable base.

Basic formula: Accounting Profit + Additions - Exclusions = Taxable Profit (Lucro Real)

Additions (Increase Taxable Base)

Expenses recorded in accounting that are not deductible for tax purposes:

• Fines for tax infractions
• Donations above legal limits
• Provisions not yet realized
• Non-operational losses above certain thresholds

Exclusions (Decrease Taxable Base)

Items that reduce the taxable base:

• Tax-exempt revenues
• Prior-year losses (limited to 30% of current profit)
• Specific investment incentives

When Lucro Real Is Mandatory

Certain companies have no choice — they must use Lucro Real:

• Annual gross revenue exceeding R$ 78 million
• Financial institutions (banks, insurance companies, credit cooperatives)
• Companies with profits from abroad
• Factoring companies
• Companies receiving specific tax incentives that require Lucro Real
• Companies with suspended or reduced tax payments based on monthly estimates

Tax Rates

Tax	Rate	Base
IRPJ	15%	Adjusted taxable profit
IRPJ surcharge	10%	Profit exceeding R$ 20,000/month
CSLL	9%	Adjusted taxable profit
PIS	1.65%	Revenue (non-cumulative, with credits)
COFINS	7.6%	Revenue (non-cumulative, with credits)

Non-Cumulative PIS/COFINS

A critical difference from Lucro Presumido: under Lucro Real, PIS and COFINS rates are higher (1.65% and 7.6% vs. 0.65% and 3%), but companies can claim credits on inputs, raw materials, depreciation, rent, and other costs. For companies with significant input costs, the net tax burden can be lower.

Calculation Periods

Companies under Lucro Real can choose between two calculation methods:

Quarterly Calculation

• Profit calculated every quarter (March, June, September, December)
• IRPJ and CSLL paid based on quarterly results
• Simpler administration but less flexible

Annual Calculation with Monthly Estimates

• Final profit determined at year-end
• Monthly advance payments based on estimated profit or revenue-based presumption
• Allows adjustments and can reduce cash flow impact
• Requires LALUR balancete (balance sheet) for suspension or reduction

The LALUR

The LALUR (Livro de Apuração do Lucro Real) is the mandatory book where all adjustments to accounting profit are recorded. It has two parts:

• Part A: Records additions, exclusions, and compensations for each period
• Part B: Controls values that will affect future periods (accumulated losses, deferred items)

Since 2014, the LALUR is filed digitally through the ECF (Escrituração Contábil Fiscal) within the SPED system.

When Lucro Real Saves Money

Scenario	Why Lucro Real wins
Low profit margins (under 8-12%)	Taxes on actual profit are lower than presumed rates
High input costs	PIS/COFINS credits reduce effective tax rate
Operating losses	Losses can offset future profits (up to 30%)
Heavy depreciation	Asset depreciation reduces taxable base
Startup phase with losses	No tax due when there is no profit

When to Avoid Lucro Real

• Your actual margins are higher than Lucro Presumido’s presumption rates
• Your accounting structure cannot support the bookkeeping requirements
• Your PIS/COFINS credits are minimal (making non-cumulative rates more expensive)

Accounting Requirements

Lucro Real demands complete and meticulous accounting:

• Monthly trial balances (balancetes)
• Full income statements and balance sheets
• LALUR maintenance
• Digital bookkeeping via SPED (ECD and ECF)
• Proper documentation for all deductions claimed

This significantly increases accounting costs compared to Simples Nacional or Lucro Presumido. Budget an additional R$ 500–2,000/month in accounting fees for Lucro Real compliance.

SedeFiscal’s Role

Your fiscal address does not determine your tax regime, but having a properly documented address from SedeFiscal ensures smooth compliance across all SPED filings. Companies under Lucro Real should work closely with a specialized accountant — SedeFiscal can connect you with accounting partners experienced in this regime.
