• Specified taxpayers are large taxpayers under BIR and EOPT Act, e-commerce businesses, and CAS/CBA users.
• E‑invoice Philippines must be generated by the system in structured JSON format and sent to the BIR. 
• You get additional tax incentives like a setup cost deduction at 100% if you are a Micro and Small taxpayer and 50% as a Medium and Large taxpayer under the CREATE MORE Act.
• If you fail to meet E-invoicing laws, you will attract a penalty of ₱1,000 to ₱50,000 per offence. 

What is e Invoicing in Philippines?

E invoicing in Philippines is the process of raising, sending, and storing invoices in a structured electronic format using the BIR-registered software or systems. It is not the same as a scanned paper copy or a PDF saved from a Word file. e-Invoice Philippines is a compliant e-invoice generated by the system in a machine-readable format, typically JSON. Key documents covered under the EIS include sales invoices, official receipts, service billings, debit notes, and credit notes.

The specified businesses must integrate their accounting or billing systems with the Electronic Invoicing System (EIS) in the Philippines to send invoice data directly to the BIR, without manual work. 

Below laws govern Philippines e-invoicing mandates:

• e-Invoicing provisions are in the Sections 237 and 237-A of the National Internal Revenue Code (NIRC), as amended by the CREATE MORE Act.
• You can know the implementation rules primarily from the Revenue Regulations No. 11-2025 (dated 27th February 2025).
• 31st December 2026 is new e-Invoicing deadline as per the Revenue Regulations No. 26-2025 (dated 5th September 2025).

E-Invoicing Philippines Timeline (Mandatory Date 2026)

The Philippines e-invoicing is implemented in phases. Here is the timeline from pilot to the current mandatory deadline.

Who Needs to Comply with e-Invoicing in the Philippines?

RR No. 11-2025 divides covered taxpayers into two groups with different obligations and timelines.

Group 1 - Mandatory Deadline: 31st December 2026

The following taxpayers must issue structured e-invoices by 31st December 2026:

• E-commerce and internet businesses- Businesses selling digital goods, digital content, online services, digital financial services, online entertainment, or conducting social/platform commerce transactions (classified as Small, Medium, or Large Taxpayers)
• Large Taxpayers under the BIR's Large Taxpayers Service (LTS)
• Large Taxpayers classified under the Ease of Paying Taxes (EOPT) Act (RA 11976) and RR No. 8-2024, generally businesses with annual gross sales exceeding PHP 1 billion
• Businesses using Computerised Accounting Systems (CAS), Computerised Books of Accounts (CBA) with electronic invoicing, or other invoicing software capable of producing structured data

Important: If a business has a head office and branch offices, all locations must comply, not just the head office.

Group 2 - No Firm Deadline Yet (Pending BIR System Readiness)

The following taxpayers will be required to comply only after the BIR establishes a system capable of storing and processing the required data. A separate Revenue Regulation will set their deadline.

• Exporters of goods and services (under Sections 106 and 108 of the Tax Code)
• Registered Business Enterprises (RBEs) availing of tax incentives under Section 304(D)
• Point-of-Sale (POS) system users
• Other taxpayers as designated by the BIR Commissioner

e-Invoicing Requirements in Philippines

To issue a compliant e-invoice, businesses must meet the following requirements under RR No. 11-2025.

1. Use EIS-Compliant Software

Your invoicing system, whether an ERP, accounting platform, or standalone billing software, must generate structured invoice data and connect to the BIR EIS via API.

Note: The BIR does not accredit or certify software vendors. Any product marketed as 'BIR-accredited e-invoicing software' is a marketing claim, not an official BIR designation. Evaluate solutions against BIR's published technical specifications.

2. Obtain a Permit to Transmit (PTT)

Covered businesses must apply for EIS Certification and a Permit to Transmit (PTT) from the BIR before transmitting invoice data. Only mandated or notified taxpayers can apply.

3. Issue Invoices in Structured Format

Invoices must be in JSON format (the BIR's primary format). Alternatively, XML is also allowed but not for transmission. Plain PDFs, Word documents, and scanned paper copies do not qualify as e-invoices under RR 11-2025.

4. Include All Mandatory Fields

Every e-invoice must contain at least 20 mandatory data fields.

5. Transmit to BIR

Invoice data must be transmitted to the BIR EIS. Wave 2 will have a transmission timeline defined for 3 calendar days.

6. Maintain a Digital Archive

Businesses must keep a retrievable electronic archive of all issued invoices and transmission logs, accessible to the BIR during audits.

• Unique document ID (linked to the transaction)
• Issue date and precise timestamp
• Seller's legal name, address, and BIR TIN
• Buyer's legal name, address, and BIR TIN
• Line items for goods/services description, quantity, and unit
• Taxable value, charges, discounts, and adjustments
• VAT rate (12% VATable, 0% Zero-Rated, or VAT-Exempt)
• Tax label: 'VATables Sale', 'Zero-Rated Sale', or 'VAT-Exempt Sale'
• Grand total (including taxes)

How Philippines e-Invoicing Works: Step-by-Step Process

Step 1: Register with the BIR EIS Portal

The business registers on the BIR EIS portal and applies for EIS Certification. Only taxpayers mandated or notified by the BIR can register. Once approved, the BIR grants a Permit to Transmit (PTT).

Step 2: Integrate Your Invoicing System

Link your ERP, accounting, or billing software to the BIR EIS using a system-to-system API. You must generate structured invoice data in JSON format that is as per the BIR's invoice schema format.

Step 3: Generate the e-Invoice

When you have a transaction, the system automatically generates a structured invoice with all mandatory fields. It replaces manual paper invoices or unstructured PDF.

Step 4: Transmit Data to the BIR EIS

The invoice data is transmitted via API to the BIR EIS. The BIR platform validates the data against the prescribed schema.

Step 5: Issue the Invoice to the Buyer

Once the e-invoice is generated and transmitted, it is issued to the buyer. Both the business and buyer can access the transaction digitally for reconciliation and audit purposes.

Step 6: Archive the Records

All e-invoices and transmission logs are stored in a digital archive. Electronic records replace paper copies, subject to BIR system readiness.

Philippines e-Invoicing Framework

The Philippines e-invoicing framework can be understood from the chart below:

Who is Exempted from e-Invoicing?

Under RR No. 11-2025, the following taxpayers are not currently required to issue structured e-invoices:

 Note: Micro Taxpayers who voluntarily adopt e-invoicing and electronic sales reporting can still claim the additional deduction on setup costs under the CREATE MORE Act.

e-Invoicing Compliance Guidelines

1. Confirm Applicability and Deadline

Verify if your business is classified as a large taxpayer, e-commerce business, CAS/CBA user, or exporter. Check whether you fall under Group 1 (31st December 2026) or Group 2 (TBD).

2. Audit Your Invoicing Infrastructure

Get a confirmation from your current ERP, billing, or accounting software provider if it can produce structured JSON invoice data and transmit it to the BIR EIS via API. Having an existing CAS accreditation does not mean EIS compliance, as they are separate systems.

3. Register with the BIR EIS

Apply for EIS Certification and a Permit to Transmit (PTT) through the BIR portal. Only mandated or notified taxpayers can apply. The BIR does not certify software vendors or evaluate solutions independently.

4. Integrate and Test Your System

Connect your invoicing software to the BIR EIS via API. Conduct end-to-end testing: invoice generation, data mapping, JSON schema validation, and transmission workflows. Resolve exceptions before the deadline.

5. Train Your Finance and IT Teams

Brief your finance, accounting, and IT staff for the new workflow.

6. Ensure All Offices Are Covered

If your business has branches, all offices must comply including the head office. Document branch readiness as part of your transition plan.

7. Maintain Clean Data Hygiene

Clean up your chart of accounts, buyer TIN records, invoice data fields, and transaction tagging before the deadline. Inaccurate master data will cause transmission failures.

Benefits of e-Invoicing for Philippine Businesses

Switching to e-invoicing offers concrete advantages, both financial and operational.

Additional Tax Deduction (CREATE MORE Act)

Businesses that adopt e-invoicing and electronic sales reporting (mandated or voluntarily) can claim an extra deduction from taxable income: 100% of setup costs for micro and small taxpayers, and 50% for medium and large taxpayers. It is on top of the standard deduction under Section 34(A)(1) of the Tax Code. The deduction can be claimed once within the taxable year the system is completed, or the final payment is made.

Reduced Manual Effort

Finance teams will start spending lesser time and lower manual efforts on billing, reconciliations and tax reporting since invoice generation and transmission all get automated.

Fewer Errors

There’ll be drastic fall in human errors because of structured and consistent invoice data formats, in the areas of VAT calculations, tax reporting, and record-keeping.

Real-Time Audit Readiness

Digital archives and transmission logs mean businesses are audit-ready at any time, reducing the risk of disputes and re-work.

Cost Savings

Eliminating printing, physical storage, and manual data entry reduces operational costs over time.

Faster Reconciliation

Automated invoice matching speeds up payment cycles and improves cash flow management.

Fraud Prevention

Traceable digital records make invoice manipulation and tax evasion harder to execute.

Exemption from Summary List of Sales (SLS)

Taxpayers using the EIS are exempt from filing the traditional Summary List of Sales, being one less periodic compliance obligation.
