ECD 2026: deadline, mandatory requirements, and how to ensure efficient delivery

Understand the current rules and what to consider in order to submit your bookkeeping securely and with peace of mind

Digital Accounting Bookkeeping (ECD) is one of the main ancillary obligations of the tax calendar.

As established by RFB Regulatory Instruction No. 2003/2021, which defines the rules related to ECD, the following points regarding this requirement should be highlighted:

ECD 2026 deadline

The ECD must be sent annually to the Public Digital Bookkeeping System (Sped) by the last business day of June of the year following the calculation period. Thus, for the base year 2025, it must be sent by June 30 of this year.

Who is required to submit the ECD 2026 

What comprises the ECD

The ECD brings together, in digital form, the main accounting books, such as:

• Journal and its auxiliary books;
• Ledger and its auxiliary books;
• Daily balance sheets, including balance sheets and entry forms that support the accounting records.

It is worth emphasizing that these files must be digitally signed by the Legal Representative and the Accountant, using a digital certificate issued by an entity accredited by ICP-Brasil.

Relationship between ECD and ECF 2026

It is essential to pay attention to the cross-referencing of information between the ECD and the Tax Accounting Bookkeeping (ECF). This is because the data sent in the ECD is later used to fill out the ECF. In other words, reconciliation between the two is vital for compliance.

How to ensure efficient delivery

To transmit the ECD with greater peace of mind and reduce risks, it is advisable to seek specialized support. Among the advantages are:

1. Continuous updating

As layouts and bookkeeping versions undergo frequent changes, a specialized partner monitors these changes and ensures greater accuracy in preparation.

2. Personalized support

Service tailored to the company's reality and the particularities of the business contributes to a more assertive fulfillment of the obligation.

3. Integrated solutions

Having joint accounting and tax support provides a complete overview of the process, avoiding discrepancies.

4. Technology for prior validation

The ECD must be submitted without inconsistencies, errors, or missing information. Therefore, the use of automated and reliable accounting systems that perform analyses prior to transmission is essential to ensure data integrity.
