The ECF (Fiscal Accounting Bookkeeping) is one of the most important obligations for companies not under the Simples Nacional tax regime. It replaced the former DIPJ and is now a key tool used by the Brazilian Federal Revenue Service (Receita Federal) to monitor how companies calculate Corporate Income Tax (IRPJ) and Social Contribution on Net Profit (CSLL).

With the modernization of Brazil’s tax system, the ECF became part of the SPED (Public Digital Bookkeeping System), allowing for automated cross-checking of accounting, tax, and financial information. This makes proper and timely submission even more critical, as inconsistencies or delays can result in significant penalties.

The ECF for the 2024 calendar year must be submitted by July 31, 2025. Even if the deadline seems far off, early planning is essential to ensure everything is in order.

🧩 What’s the difference between ECD and ECF?

A common question among business owners — and even some professionals — is the difference between ECD and ECF. While both are submitted digitally and are part of SPED, their purposes are quite different.

The ECD (Digital Accounting Bookkeeping) focuses on a company’s accounting records, such as the General Ledger, Journal, and Financial Statements, serving as formal proof of its regular bookkeeping.

The ECF, on the other hand, is primarily used to show the Receita Federal how the company calculated its IRPJ and CSLL. It starts from the company’s accounting results and applies tax adjustments according to legislation to arrive at the taxable profit.

In simpler terms: ECD shows how a company records its transactions; ECF shows how it calculates and pays taxes on its profits.

🏢 Who must file the ECF?

Not all companies are required to file the ECF, so it’s important to know whether your company falls within the Federal Revenue’s requirements.

The following must submit the ECF:

• Companies taxed under the Actual Profit Method (Lucro Real) – mandatory;
• Companies taxed under the Presumed Profit or Arbitrary Profit regimes;
• Tax-exempt or immune entities, provided they are required to file the EFD-Contributions;
• Silent Partnerships (SCPs), as applicable.

Exempt from filing:

• Companies under the Simples Nacional regime, which follow separate tax rules;
• Inactive legal entities — those that carried out no operational or non-operational activity during the year;
• Public agencies, autarchies, and public foundations.

If you’re unsure about your company’s classification, it’s best to consult your accountant to avoid oversights.

⏳ Deadline and submission considerations

The ECF must be filed by July 31, 2025, which falls on a Thursday. As with other SPED obligations, submission is done through a validation software (PVA) provided by the Receita Federal.

However, the process of filling out and validating the ECF is not straightforward. It requires data reconciliation, especially with the ECD, and proper tax calculation. Therefore, companies are strongly advised not to leave this task to the last minute.

Aside from the risk of system instability close to the deadline, technical errors or omissions may prevent submission or lead to fines.

🚫 What happens if the ECF is not submitted?

Failing to submit the ECF — or submitting it with significant errors — can seriously affect a company’s financial health and tax compliance.

Major consequences include:

• Late filing fines, which may reach BRL 1,500.00 per month, depending on the company’s tax regime;
• A penalty of up to 0.25% of gross revenue, capped at 10% of net profit, in more serious cases;
• Inability to obtain negative debt certificates, affecting access to public bids or credit lines;
• Stricter audits, especially if discrepancies with other tax obligations are found.

For these reasons, submitting the ECF should be treated with the same priority as paying taxes and maintaining regular accounting.

📑 What’s new in 2025?

Although the ECF’s general structure doesn’t change drastically year over year, it’s important to monitor updates to the PVA layout, which are published by the Receita Federal and may require technical adjustments in your file generation.

Moreover, tax law changes — such as incentives, compensation rules, or new profit calculation guidelines — can directly impact how the ECF is completed. Companies involved in corporate reorganizations, spin-offs, or mergers must be especially attentive to the bookkeeping process.

That’s why reviewing the applicable tax legislation for the 2024 fiscal year is a key step in preparing for the 2025 submission.

✅ How to prepare in advance

The best way to avoid issues is to start preparing the ECF well in advance. Key actions include:

• Validating the ECD to ensure balances and entries are correct;
• Reviewing the fiscal adjustments for IRPJ and CSLL calculations;
• Updating and integrating the company’s chart of accounts with the Receita Federal’s reference structure;
• Checking the company and shareholder registration data;
• Using the ECF PVA tool to simulate and pre-validate the file.

Additionally, working with a qualified and up-to-date accounting professional is essential to ensure each stage is handled with technical accuracy.
