1. What is the ECF and why is it mandatory?
The Tax Accounting Bookkeeping (ECF) is an ancillary obligation required by the Brazilian Federal Revenue Service, which replaced the Corporate Economic-Tax Information Return (DIPJ). Its main purpose is to allow the Brazilian Federal Revenue Service to cross-reference companies' tax and accounting data, ensuring greater transparency and tax oversight.
The ECF must be filed annually by all legal entities taxed under the Actual Profit (Lucro Real), Presumed Profit (Lucro Presumido), or Arbitrated Profit (Lucro Arbitrado) regimes, with some exceptions. Companies that fail to meet the obligation by the set deadline will be subject to severe fines and sanctions.
2. What are the main changes in the 2025 ECF?
The Brazilian Federal Revenue Service approved the ECF Layout 11, introducing a series of structural changes to the fiscal bookkeeping. See the main changes below:

Change of relationship type to "3" (with Part B Account and Accounting Account) for some M300 and M350 records. This requires companies to adjust the accounting classification of their operations.
New records and accounting accounts:

3. Deadlines and penalties for the 2025 ECF
The filing deadline for the 2025 ECF is the last business day of July 2025. Companies that fail to meet the obligation within the deadline will be subject to fines that vary according to the applicable tax regime:
- Actual Profit (Lucro Real): 0.25% of gross revenue per month of delay, capped at 10%
- Presumed Profit (Lucro Presumido): 0.02% of gross revenue per day of delay, capped at 10%
In addition to financial penalties, non-compliance with the ECF may result in tax restrictions and difficulties in obtaining clearance certificates (certidões negativas de débito), affecting the company's good standing with the tax authorities.
