If you sell on Shopee, Lazada, TikTok Shop, or through your own Facebook page, you have probably seen a small deduction appear on your payouts and wondered what it is — or gotten a message from a platform asking for your "COR." The short answer to the question everyone is asking about BIR registration for online sellers Philippines: yes, in almost every case, you are legally required to register, and the marketplaces are now actively enforcing it.
This guide breaks down who needs to register, the thresholds that actually matter, what the 1% withholding tax is, and how to stay compliant without drowning in paperwork.
Do online sellers really need to register with the BIR?
Under Revenue Regulations No. 15-2024, anyone conducting business through a website, social media, or an e-marketplace is treated the same as a physical store owner. That means selling online is a taxable business activity — whether you ship from a warehouse or from your bedroom.
Here is the part that changed the game: since 15 July 2024, e-marketplace operators like Shopee and Lazada have been required to collect a 1% creditable withholding tax on remittances to their sellers. To keep selling on their platforms, they now ask you to submit your BIR Certificate of Registration (COR / Form 2303). No COR, and your account can be restricted, held, or delisted.
So the practical reality in 2026 is simple:
- Marketplace sellers (Shopee, Lazada, TikTok Shop): the platform will require your COR to keep your store active.
- Facebook / Instagram / Viber sellers: you are equally covered by the law, even though no platform is withholding on your behalf. The obligation is on you.
- Resellers, dropshippers, and "sideline" sellers: still a business in the eyes of the BIR, regardless of how small.
A common myth is that social sellers are exempt because "walang platform na naniningil." Not true. The registration duty comes from the law, not from whether a marketplace is deducting tax for you.
The two thresholds you must not confuse
Most of the confusion online sellers face comes from mixing up two completely different numbers. They do different things.
| Threshold | What it means | What it does |
|---|---|---|
| ₱250,000 taxable income/year | The income-tax-free bracket | You still register, but you may owe zero income tax if your taxable income stays at or below this |
| ₱500,000 annual gross remittances | Marketplace withholding trigger | Below this, Shopee/Lazada should not deduct the 1% withholding tax |
| ₱3,000,000 gross sales/year | The VAT threshold | Below this you can use the simpler 8% flat tax; above it you become VAT-registered |
The key takeaway: being below ₱250,000 or below ₱500,000 does not exempt you from registering. It only affects how much tax you pay or whether the platform withholds. Registration itself is required from day one of doing business.
The ₱500,000 marketplace exemption
If your cumulative gross remittances from a marketplace for the year have not exceeded ₱500,000, the 1% withholding tax should not apply to you. Many small sellers qualify — but you often need to be properly registered and have submitted your details for the platform to apply the exemption correctly. If you see the deduction and you are under the threshold, that is usually a registration or documentation gap on your end, not a bug.
What registration actually looks like
For a typical solo online seller (sole proprietor), the path is straightforward:
- DTI Business Name registration (for your store name).
- Barangay clearance and Mayor's Permit from your LGU.
- BIR Form 1901 to register as a self-employed individual, plus payment of the annual registration fee where applicable, and get your COR (Form 2303).
- Register your books and get authority to print / register your receipts (or an accredited e-receipt solution).
- Display your COR / registration badge — RR 15-2024 requires it to be visible on your online store, and under the newer RMC 038-2026 many sellers must post the government-issued registration seal badge on their marketplace profile or page.

How much tax will you actually pay?
For most online sellers earning purely business income and staying under the ₱3M VAT threshold, the 8% flat tax is the simplest option. You add up your gross sales, subtract the ₱250,000 exemption, and multiply the balance by 8%. This single rate covers both your income tax and the 3% percentage tax, so you skip the quarterly 2551Q filings entirely.
- Registration: BIR Form 1901.
- Quarterly income tax: BIR Form 1701Q.
- Annual income tax return: BIR Form 1701A (deadline 15 April 2026 for the 2025 year).
- The 1% marketplace withholding tax is creditable — it is not an extra tax. You deduct what Shopee or Lazada already withheld from what you owe at filing time.
If your taxable income for the year lands at or below ₱250,000, your income tax can be zero — but you are still expected to file the returns to prove it.
Getting your records in order — the real work
Registration is a one-time hurdle. The ongoing challenge is keeping clean records of every sale, especially when orders arrive across Shopee, Lazada, Messenger, Instagram, Viber, and WhatsApp all at once. When your sales are scattered across chat threads, reconciling them against your BIR filings becomes a monthly headache.
This is where centralising your order-taking helps you stay compliant almost by accident. If every enquiry and order flows through one place, you have a searchable record of what you sold and to whom. Tools like Remarketly pull Viber, Messenger, Instagram, and WhatsApp into a single inbox, and you can even set up a chatbot that takes orders and delivery details automatically so nothing slips through unrecorded. For payments, sending a proper GCash payment link or QR Ph right from the chat gives you a clean, timestamped trail that matches your books far better than screenshots of "sent na po."
Quick answers to the questions sellers ask most
- I only sell on Facebook, walang marketplace — kailangan pa rin? Yes. The law covers all online selling, not just marketplaces.
- Below ₱250k lang ang kita ko. You still register; you may just owe no income tax.
- The platform is deducting 1% but I'm under ₱500k. That usually points to a registration or documentation gap — fix your BIR details and submit your COR to the platform.
- Is the 1% an extra cost? No. It is creditable against your income tax when you file.
Registering with the BIR is no longer optional for serious online sellers — the marketplaces have made sure of that. The good news is that once you are registered and your orders flow through one organised system, staying compliant becomes routine rather than a scramble every April.
