Updated July 19, 2026Reviewed against BIR RR 11-2025 (Feb 27, 2025) & RR 26-2025 (Oct 16, 2025) as of July 19, 2026

The BIR e-invoicing deadline: December 31, 2026

The headline date is December 31, 2026. That is when covered taxpayers must be issuing structured electronic invoices under the BIR e-invoicing mandate. It was set by RR 26-2025, which extended the original window in RR 11-2025 — here is the full timeline and what each date actually means.

Key Takeaways

  • Deadline: December 31, 2026 to comply with the electronic-invoice issuance requirement.
  • RR 11-2025 (Feb 27, 2025) set the framework and a one-year compliance window; RR 26-2025 (Oct 16, 2025) extended it to December 31, 2026.
  • The deadline is for issuing structured invoices — real-time transmission to the EIS is a separate, later step.
  • RR 26-2025 did not change who is covered — only the date. Start the changeover months ahead, not on the deadline.

When is the BIR e-invoicing deadline?

December 31, 2026. Under RR 11-2025, covered taxpayers originally had one year from the regulation's effectivity to comply with electronic-invoice issuance. RR 26-2025 (October 16, 2025) extended that compliance deadline to December 31, 2026, giving covered taxpayers more time to reconfigure their systems for the transition.

What exactly must be done by December 31, 2026?

Covered taxpayers must be issuing structured electronic invoices — machine-readable data from a registered system, not paper or static PDFs. Real-time transmission to the EIS is not required by this date; it phases in once the BIR's receiving system is established under a separate regulation.

Confirm whether you are in a covered group in the EIS compliance guide and the micro-taxpayer exemption. Missing the date carries consequences — see BIR e-invoicing penalties.

How much lead time does an agency need?

More than most expect. Moving client billing onto a system that issues structured invoices, mapping VAT/EWT and the admin fee, and registering the system with the BIR as a CAS all take time — CAS registration alone is a documentary process. Plan the changeover months before December 31, 2026.

The step-by-step path is on how to become EIS-ready.

Frequently asked questions

December 31, 2026. RR 11-2025 (issued February 27, 2025) originally gave covered taxpayers one year to comply; RR 26-2025 (issued October 16, 2025) extended the compliance deadline to December 31, 2026 without changing which taxpayers are covered.

Yes. RR 26-2025 extended the deadline to December 31, 2026 from the earlier one-year compliance window set by RR 11-2025, in recognition of the system reconfiguration covered taxpayers need for the transition.

No. The December 31, 2026 deadline is for issuing structured electronic invoices. Real-time transmission through the Electronic Sales Reporting System begins once the BIR establishes the system to receive the data, under a separate Revenue Regulation.

Well before year-end 2026. Moving client billing to a system that issues structured invoices, and registering it with the BIR as a CAS, takes lead time — plan the changeover months ahead of December 31, 2026, not on it.

General information, not legal or tax advice. Confirm the December 31, 2026 deadline against the Bureau of Internal Revenue (bir.gov.ph) and the text of RR 11-2025 and RR 26-2025.

Beat the December 31, 2026 deadline.

NexusWorkforce issues EIS-ready, CAS-registrable invoices from the DTR that runs your payroll — so the changeover is a setup, not a migration. Start well before year-end 2026.
