Monthly Tax Declaration Deadline for Non-E-Filing Legal Entities: August 28

For legal entities that are not enrolled in the remote filing and payment system, the monthly tax declaration must be submitted no later than the 28th of each month.

📅 Key Deadline for August

In August, this deadline falls on Friday, August 28, which also coincides with the last day of the single business session. Affected companies must mark this date on their calendars to ensure timely compliance with their tax filing obligations.

🎯 Who Does This Apply To?

This requirement specifically targets legal entities that do not use the e-filing platform. Companies already registered for remote filing and payment are subject to the separate procedures and deadlines established for that digital system.

⚖️ Why Timely Submission Matters

Meeting this deadline is essential for businesses to:

• ✅ Avoid late filing penalties and interest charges
• ✅ Prevent administrative sanctions or compliance flags
• ✅ Maintain good standing with tax authorities

Staying on schedule ensures smooth financial operations and helps companies sidestep unnecessary legal or financial complications.

Note: This notice applies exclusively to non-adherent legal entities. E-filing users should refer to their platform-specific guidelines for submission windows and payment processing.
