The mandate explained

The BIR e-invoicing mandate is here.
It's bigger than your IT team thinks.

Revenue Regulation 11-2025 is not a form update. It's a fundamental change to how Philippine businesses issue, sign, and report invoices and the deadline is December 31, 2026.

What you must comply with

Transmission model

Post-audit. Invoices delivered directly to buyers, no BIR clearance required.

Applicability

Large Taxpayers, e-commerce businesses, and any enterprise using ERP or accounting software. In scope regardless of sales volume.

Acceptable formats

JSONs only. PDFs and scanned invoices do not qualify. Digital signature required on every invoice.

Transactions covered

Sales invoices, official receipts, service billings, credit and debit notes. If any branch is in scope, all locations must comply.

Penalties & incentives

50–100% tax deduction on implementation costs for early adopters. Non-compliance: invoices invalidated, input tax deductions lost.

One platform

Every step of the mandate, handled.

The Philippines mandate has two tracks, two sets of BIR registrations, and a 3-day reporting window that never stops. ClearTax covers it all, connected directly to your ERP.

See the platform in action →
Step 01
CAS Registration Support
Before you can issue a single invoice, BIR requires an Acknowledgement Certificate. An incomplete submission restarts the clock. Our compliance consultants walk your team through the Compliance Dossier Report submission to your RDO, so nothing gets rejected.
Step 02
Structured Invoice Issuance
ClearTax pulls data from your ERP, transforms it into BIR-compliant JSON, applies the required JWS digital signature (RS256), and delivers the signed invoice directly to your buyer. No BIR clearance gate. No manual steps.
Step 03
EIS Onboarding & PTT Support
Your Permit to Transmit and EIS Certificate are issued to you, not your vendor. We manage the joint UAT with BIR and ensure your team is certified on time, so the 3-day clock never catches you unprepared.
Step 04
Automated ESRS Reporting
Once BIR infrastructure goes live, ClearTax automatically transmits the same invoice payload to BIR EIS within the 3-day window. Idempotent retries, cancellation and amendment payloads are handled by the platform, not your team.
Step 05
Reconciliation & Audit Readiness
ClearTax continuously reconciles your GL data against EIS-reported invoice data. AI surfaces mismatches, value gaps, and missing documents before BIR flags them, so audits stay routine reviews rather than board-level escalations.
Built for compliance

Engineered to last.

Every feature is designed around one goal: keeping you compliant automatically, no matter how BIR regulations evolve.

Regulatory Assurance

Our in-house team of tax experts tracks every BIR update, new fields, amended schemas, regulatory circulars, and deploys changes to the platform. Your ERP connector doesn't change. Your IT team doesn't get a ticket.

AI-Powered Failure Prevention

ClearTax detects duplicate invoices, abnormal values, timing gaps, and vendor anomalies before transmission. No auto-healing means failed invoices pile up and create penalty risk. Ours don't.

Smart Reconciliation Dashboard

A central MIS dashboard tracks every invoice, generated, pending, failed, with one-click filters and exportable reports. AI surfaces only the critical mismatches that need action.

Why ClearTax

Other vendors sell e-invoicing software. We deliver compliance assurance.

1 in 5 invoices fail in Malaysia due to poor validation. 30% of enterprises in KSA face data-structure rejections. The Philippines' mandate is no different, a failed invoice here isn't just an inconvenience. It's a penalty and a lost VAT deduction.

FAQs

Frequently asked questions

Everything you need to know about Philippines e-invoicing and ClearTax.

What is e‑invoicing in the Philippines?
E‑invoicing in the Philippines is the BIR‑mandated process of issuing invoices in structured JSON format and reporting them to the Electronic Invoicing System (EIS) at eis.bir.gov.ph. It is mandated to take effect from 31 December 2026 under RR No. 26‑2025 for large taxpayers, e‑commerce platforms, and ERP users.
What are the key features of ClearTax e‑invoicing software in the Philippines?

The mandate requires covered taxpayers to issue invoices and receipts as signed JSON files and transmit them to the BIR within three days. ClearTax offers a complete solution that removes the need for in‑house development by finance and IT teams.

With ClearTax, businesses can:

  • Easily connect with more than 60 ERPs and billing solutions, including SAP, Oracle, and Microsoft Dynamics.
  • Convert invoice data into the required JSON format, apply the JWS signature, and validate each file before submission.
  • Submit invoices directly to the EIS via API, with built‑in confirmation, error handling, and resubmission features.
  • Store documents securely for 10 years in line with BIR requirements, with reconciliation and audit support included.
  • Access CAS registration support, Permit to Transmit, and BIR testing with guidance from experts in both regulation and technology.
  • Always stay compliant as ClearTax updates its platform in near real time to reflect changes in EIS rules and timelines. We have been a global e‑invoicing platform across more than 50 countries since 2017. You can use a single platform to go live for e‑invoicing across many countries.
Why do global enterprises choose ClearTax for the Philippines e‑invoicing?
ClearTax processes over 1 billion e‑invoices annually for 5,000+ enterprises across 50+ countries. One ERP integration covers the Philippines (EIS), Malaysia (MyInvois), Singapore (InvoiceNow), Saudi Arabia (ZATCA), India, UAE, and France, so enterprises scale compliance without rebuilding.
Which ERP and accounting systems does ClearTax integrate with?
ClearTax integrates with SAP (S/4HANA, ECC, Business One), Oracle (EBS, Fusion, NetSuite, JD Edwards), Microsoft Dynamics 365, Shopify, and 95+ custom ERPs via its rapid deployment thin connectors and integration agent. It ensures fast deployment and zero disruption. Connection methods include API, SFTP and bulk Excel ingestion for non‑API upload, with a 4x faster go‑live typically in weeks.
Does ClearTax support both Phase 1 and Phase 2 of the Philippines e‑invoicing mandate?
Yes. ClearTax supports the first mandatory group under RR No. 11‑2025 covering e‑commerce, LTS, Large Taxpayers under the EOPT Act, and CAS/CBA users to comply by 31 December 2026 (RR No. 26‑2025). It is also ready for the next wave: exporters, Registered Business Enterprises with tax incentives, and POS users, who will be onboarded once the BIR's Electronic Sales Reporting System (ESRS) goes live.
How does ClearTax automate invoice reporting to the BIR EIS?
ClearTax pulls invoice data from your ERP, converts it to BIR‑compliant JSON, applies the JWS digital signature, validates against 200+ EIS rules, and transmits to eis.bir.gov.ph in real time. The BIR acknowledgement is returned to the ERP and archived for the statutory 10‑year period.
How does ClearTax ensure the security of invoice and tax data?
ClearTax is SOC 2 Type II and ISO 27001:2022 certified, with AES 256‑bit encryption at rest, TLS in transit, role‑based access, audit logging, and local data residency in the Philippines. Customer data is never used to train AI models.
Is ClearTax accredited by the BIR for the Philippines e‑invoicing?
ClearTax generates BIR‑compliant electronic invoices aligned with RR No. 11‑2025 and the EIS technical specifications, including JSON formatting, JWS signing, and EIS transmission.
How many countries does ClearTax support for e‑invoicing compliance?
ClearTax supports e‑invoicing compliance in 50+ countries, including the Philippines, India, Malaysia, Singapore, Saudi Arabia, UAE, France, Belgium, Spain, Poland, Oman, Bahrain, Kuwait, Qatar, and the Peppol network.
Does ClearTax support e‑invoicing for companies operating across Southeast Asia?
Yes. ClearTax is live for the Philippines (BIR EIS), Malaysia (LHDN MyInvois), and Singapore (IRAS InvoiceNow / Peppol), with one integration covering all ASEAN markets. Adding a new country is a configuration change, not a re‑implementation.
Can ClearTax handle high invoice volumes for large enterprises?
Yes. The ClearTax platform handles 10,000 invoices per second, generates invoices in 200‑300 ms, and processes over 1 billion e‑invoices annually, proven at month‑end, fiscal year‑end, and flash‑sale peaks for the world's largest enterprises.
