The Declaration of Socioeconomic and Fiscal Information – DEFIS is an annual ancillary obligation required from companies that opt for Simples Nacional. Although it does not involve the direct collection of taxes, the correct submission of DEFIS is essential for the company’s tax compliance and for maintaining eligibility under this tax regime.

Failure to comply with this obligation can lead to significant restrictions and impacts on the business’s tax situation, which is why the DEFIS should be included in the annual planning of companies classified under Simples Nacional.

What is DEFIS?

DEFIS is a declaration through which the company reports economic, tax and corporate data related to the previous calendar year. DEFIS replaced the former Simples Nacional Annual Declaration (DASN) and works as a control instrument used by the Brazilian Federal Revenue Service to monitor the situation of companies opting for Simples Nacional.

The data provided allows for cross-referencing data with other ancillary obligations and tax systems, contributing to the monitoring and verification of tax compliance.

Who is required to submit the DEFIS?

All companies that opt for Simples Nacional shall submit DEFIS, including:

• Microenterprises (ME); and

• Small Businesses (SBP).

The requirement is independent of whether there was revenue during the period. Even companies without economic activity or temporarily inactive must submit the declaration even if the profit is zero.

What is the deadline for submitting the DEFIS?

The DEFIS must be submitted annually until the last day of March of the year following the period indicated. As a general rule, the tax return for a given calendar year must be submitted by March 31 of the following year. In specific cases, such as the extinction, incorporation, spin-off, or merger of the company, specific rules regarding the deadline may apply, according to current legislation.

What are the consequences of not submitting the DEFIS?

Failure to submit the declaration within the legal deadline or submitting it with incorrect information may result in penalties, jeopardizing the company’s fiscal situation. Among the main risks are:

• Notice of tax irregularity;

• Restrictions on access to certificates; and

• Difficulties in fulfilling other tax obligations.

For this reason, correct filing and timely submission are essential measures for the legal and fiscal security of the company.
