If you're selling products or services online in the Philippines—whether through Shopee, Lazada, TikTok Shop, your own website, Facebook Marketplace, or Instagram—you likely need to handle BIR registration and proper invoicing. Many sellers start small and wonder when these rules kick in, how to issue valid receipts to customers, and what the new electronic invoicing requirements mean for everyday online businesses. This guide explains the current rules clearly so you can operate legally, avoid penalties, and keep your business running smoothly.

Why BIR Registration Matters for Online E-Commerce Sellers

Under Section 236 of the National Internal Revenue Code (NIRC) of 1997, as amended, every person engaged in trade or business must register with the Bureau of Internal Revenue (BIR) before starting operations or before filing any tax return or paying tax, whichever comes first. Online selling counts as business activity regardless of volume or platform. Revenue Memorandum Circular (RMC) No. 60-2020 specifically directed all online sellers and digital service providers to register, file returns, and pay taxes. Revenue Regulations (RR) No. 15-2024 added that you must register your online store name or platform presence as an additional business name tied to your head office or residence.

Registration gives you a Certificate of Registration (BIR Form 2303 or electronic COR) and lets you legally issue invoices and receipts. It also allows you to display the official BIR Registration Seal Badge on your website, online shop page, or social media store—now required under RMC No. 38-2026. This badge includes a verifiable QR code and signals to customers and platforms that you are a legitimate, registered seller. Non-registration exposes you to fines, surcharges, and possible business closure orders.

Step-by-Step Guide to Registering as an Online Seller

Most individual online sellers register as sole proprietors using BIR Form 1901. Corporations or partnerships use BIR Form 1903. You can register online for convenience or in person.

Determine your Revenue District Office (RDO) — Use the RDO covering your place of residence (for pure online sellers with no physical store) or principal place of business.
Prepare documents (scanned PDFs, total file size usually under limits for online portals):
- Accomplished BIR Form 1901 (or 1903).
- Valid government-issued ID showing your name, birthdate, and address (or separate proof of residence if the ID lacks an address).
- DTI Certificate of Registration if you use a business name.
- Final clear sample of your proposed invoice/receipt design plus BIR Form 1906 (if printing your own) or opt to buy BIR Printed Invoices (BPI) at the RDO.
- Special Power of Attorney and IDs of both parties (if someone else files for you).
Choose your registration method:
- Online Registration and Update System (ORUS) at orus.bir.gov.ph — Create an account, fill the form, upload documents, and pay the P30 documentary stamp tax (DST) online via partner banks. Print your electronic COR.
- New Business Registration (NewBizReg) Portal — Email scanned documents and the completed form to your RDO.
- Philippine Business Hub (business.gov.ph) — Integrated with DTI and other agencies for one-stop registration.
- In-person at your RDO’s New Business Registration Counter (follow single-window processing).
Complete the tax type questionnaire during registration — This determines your income tax, VAT or percentage tax, and withholding tax obligations.
Receive your COR and Notice to Issue Invoices (NII) — Display these visibly at any physical location and post the BIR Registration Seal Badge (free via ORUS or RDO) on all your online platforms, including marketplace seller pages. Use the correct Philippine Standard Industrial Classification (PSIC) or Philippine Standard Occupational Classification (PSOC) code, such as PSIC 47913 for “Retail sale via internet” or the appropriate code for content creation or services.
Register your books of accounts — Do this before your first quarterly or annual return deadline. Keep them for at least five years.

Under the Ease of Paying Taxes (EOPT) Act (Republic Act No. 11976), there is no longer an annual BIR registration fee of P500. Registration is generally processed within days if documents are complete, though follow up with your RDO if needed.

After registration, file BIR Form 1905 at the start of each year (or when changes occur) to update your tax types, including electing percentage tax if your gross sales stay below the VAT threshold.

Invoicing and Receipt Requirements

Section 237 of the NIRC requires you to issue a duly registered sales invoice or official receipt for every sale or transfer of goods or services worth P500 or more. For transactions below P500, issue one consolidated invoice or receipt at the end of the day for the aggregate amount. VAT-registered sellers must issue invoices for all amounts.

Your invoice or receipt must contain:

Your registered name, address, and TIN
Date of transaction
Description, quantity, and unit price of goods or services
Total amount and any VAT breakdown (if applicable)
Your BIR-registered invoice/receipt number and series

You have two main options while most small sellers remain exempt from mandatory electronic invoicing:

Apply for Authority to Print (ATP) your own custom invoices/receipts (submit sample with Form 1906).
Purchase BIR Printed Invoices (BPI) directly from your RDO’s New Business Registration Counter.

Many e-commerce platforms generate or allow you to upload compliant invoices through their seller centers. Always ensure the final document matches your BIR-registered series. Keep copies and supporting records (orders, payments, shipping) for audits.

Preparing for Electronic Invoicing (EIS)

The BIR is implementing the Electronic Invoicing and Electronic Sales Reporting System (EIS) under RR No. 11-2025, issued pursuant to the CREATE MORE Act (Republic Act No. 12066). Covered taxpayers must generate structured electronic invoices (typically in JSON format) using BIR-approved software or systems and transmit the data directly to the BIR’s centralized EIS for validation and reporting. You can still provide a customer-friendly PDF or visual invoice, but the underlying fiscal data must go electronically to the BIR.

Who must comply mandatorily? Large taxpayers, certain e-commerce and internet transaction businesses (including sale of physical or digital goods, operation of platforms, digital content creation for income, on-demand services, and similar online activities), exporters, and those using Computerized Accounting Systems (CAS). RR No. 26-2025 set the full compliance deadline at December 31, 2026, with some categories required earlier (phased rollout beginning around March 2026 for priority groups).

Micro taxpayers are exempt from the mandatory requirement. These are generally sellers with annual gross sales or receipts below P3 million (aligned with the EOPT classification and VAT threshold). They must continue issuing registered manual invoices or may use CAS/CRM/POS systems voluntarily. If you grow beyond micro status or your activities place you in a covered category, transition to an approved e-invoicing solution and obtain any required Permit to Transmit.

Voluntary early adoption of electronic invoicing and sales reporting qualifies micro and small taxpayers for an additional tax deduction of up to 100% of the setup costs (50% for medium and large). Monitor BIR announcements and check your classification with your RDO, as rules continue to roll out.

Common Pitfalls and Real-Life Scenarios

Many ordinary sellers face these issues:

Delaying registration until sales grow significantly — penalties and possible platform restrictions or closure risks apply from the start of business.
Using the wrong PSIC/PSOC code or failing to post the BIR Registration Seal Badge on all online platforms (including marketplace profiles) as required by RMC No. 38-2026.
Not issuing proper invoices or using unregistered series — this creates problems for buyers claiming input VAT and triggers BIR audits.
Underreporting sales across multiple platforms or confusing gross remittances with net income.
For platform sellers (Shopee, Lazada, etc.): Platforms may withhold a portion of your payouts. Submit a notarized Sworn Declaration of Gross Remittances to your RDO by the deadline (often mid-January) to properly document your sales and manage withholding.
Foreigners or non-residents: Additional rules apply. Retail trade activities have constitutional and statutory restrictions favoring Filipino citizens. Non-resident digital service providers face separate VAT obligations under related regulations. Proper setup (often through a Philippine entity) and apostilled documents are usually required. Seek specific guidance for cross-border situations.
Growing past P3 million in annual gross sales without updating to VAT registration and preparing for potential e-invoicing obligations.

Track your total sales across all channels monthly. If you also earn from content creation, affiliate marketing, or subscriptions, register those activities under the correct codes.

Frequently Asked Questions

Do I need to register with BIR if I only sell occasionally or part-time on Shopee?
Yes. Any income-generating online selling activity requires registration under Section 236 of the NIRC, regardless of how small or occasional. Start as soon as you treat it as a business.

What documents do I need to register as a sole proprietor online seller?
BIR Form 1901, valid government ID (with address or plus proof of residence), DTI certificate if using a business name, and invoice sample or BPI request. Use ORUS for the easiest process.

How do I display my BIR registration on my online shop or social media page?
Obtain the free BIR Registration Seal Badge (with QR code) through ORUS or your RDO after registration. Post it conspicuously on your website, marketplace seller page, and social store per RMC No. 38-2026. Register the correct PSIC code such as 47913 for internet retail.

When will electronic invoicing become mandatory for typical online sellers?
Micro taxpayers (generally under P3 million annual gross sales) are exempt from mandatory structured e-invoicing and can continue with registered manual invoices. Larger or covered e-commerce businesses must comply by December 31, 2026 (RR No. 26-2025), with some phases earlier. Check your classification with the BIR.

Can I still use printed or paper invoices in 2026?
Yes, if you qualify as a micro taxpayer. Larger covered taxpayers must shift to BIR-approved electronic systems that transmit structured data to the EIS while still providing customer-facing documents.

Do I need to register for VAT?
Only if your annual gross sales or receipts exceed P3 million. Below that threshold, you generally pay percentage tax (if applicable to your activity) or just income tax and remain a micro taxpayer for e-invoicing purposes.

How do platforms like Lazada or Shopee handle taxes on my sales?
They often withhold amounts for tax compliance and require proof of your BIR registration. Submit a notarized Sworn Declaration of Gross Remittances to your RDO to document your actual sales and adjust withholdings.

What happens if I don’t register or issue proper invoices?
You risk penalties, surcharges, interest, and possible business closure. Buyers may also refuse purchases or claim issues with warranties/taxes. Platforms may suspend accounts without valid registration.

Key Takeaways

Register promptly with the BIR using Form 1901 (most common for individuals) via ORUS or your RDO — it is mandatory for all online sellers under Section 236 of the NIRC.
