The acronym IRPJ refers to the Corporate Income Tax and is one of the taxes that are paid in the country. However, as the name itself says, this statement must be made by companies.

Companies must declare income tax of all sizes, including individual companies.

And in the midst of so many taxes, the businessman may feel confused. Thus, we will explain here a little more about the IRPJ.

IRPJ is calculated according to the type of taxable profit of the company.

What are the types of business taxation?

Basically, companies, depending on the type of taxable income, are classified into three types: Simple, Real Profit and Presumed Profit.


They are companies whose taxable profits are simple and, in this case, the tax is already discounted in the own tax guide (municipal, state and federal). Thus, it is not necessary to fill out extensive data guides for declaration.

The amount of tax due, in these cases, varies according to the company’s billing.

Presumed profit

Here are companies that have estimated taxable profit. These should consult a government table of percentage profit estimates – depending on the segment in which the establishment operates.

Also a tax rate on the profit of, generally, 15% is levied.

These data will serve as a tax rate for the calculation of IRPJ of these companies.

To facilitate understanding, let’s take an example:

One company had a quarterly turnover of R $ 15 thousand. According to the table, the presumed profit is 10% – the equivalent of R $ 1,500.

At a rate of 15%, the amount to be paid IRPJ tax will be R $ 225 quarterly.

But attention. If a company’s billing exceeds R $ 20,000, the tax due may add an additional 10% additional rate.

Real profit

It follows the same rule as the companies of the Assumed Profit category. Profit is taxed at a rate of 15%.

The amount obtained must be paid quarterly to the Internal Revenue Service.

I’m late with the IRPJ. How to proceed?

Now that you already know all about IRPJ, it is even more important to know that a company should never be liable for the late tax payment.

If you have not paid your company’s IRPJ, try to do so as soon as possible. Delaying company taxes entail interest and fine.

In addition, if any portions of the tax are in arrears, the company will be prevented from carrying out various transactions and may even have its activities closed – until the debts are settled.
