When setting up your business in the Philippines, one of the mandatory steps is to secure your tax registration certificate from the Bureau of Internal Revenue (BIR). This certificate, known as the BIR Certificate of Registration (COR) or Form 2303, is your business’s proof of local tax compliance.
The COR officially recognizes you as a taxpayer in the Philippines. It provides a unique Tax Identification Number (TIN) for all tax-related transactions. Moreover, it also lists the specific taxes your business must pay, such as income tax, VAT, and withholding tax etc.
In this guide, we will walk you through the essentials of securing your BIR COR (Form 2303) to ensure your business is compliant from the very beginning.
Overview of the BIR Certificate of Registration (Form 2303)
The BIR COR officially recognizes your business as a taxpayer in the Philippines. Here’s what is on the BIR Certificate of Registration:
- Tax Identification Number (TIN): A unique ID for all tax-related transactions used for filing returns, issuing invoices, and more.
- RDO code: the Revenue District Office where you are registered
- Registered name and business address
- Line of business: your registered activity
- Tax types: The COR specifies which taxes your business must pay. This includes income tax, VAT, and withholding tax, allowing you to understand your tax obligations right from the start.
Be aware that your COR carries a filing schedule, and the BIR expects a return on every due date, even for periods when you earn nothing. If you don't file your returns on time, they can turn into what is referred to as "open case". That especially becomes a problem when you are making changes such as renewals, changes in business activity, or when filing for dissolution.
Who Needs to Register with the BIR?
For anyone planning to practice a profession or operate a business in the Philippines, BIR registration is mandatory. This includes:
- Domestic corporations and partnerships
- Foreign-owned entities like branch offices, ROHQs, or subsidiaries
- Professionals such as doctors, lawyers, and accountants
- Sole proprietors and online sellers
- Freelancers and independent contractors, licensed or not
- Mixed income earners (employed plus a business or practice on the side)
Obtaining your COR is an important part of operating your business. That is because you cannot legally issue receipts, apply for additional licenses and permits, or file your taxes without it.
Requirements to Obtain A BIR COR in the Philippines
Before applying for your BIR COR, you’ll need to gather several key documents such as the SEC company incorporation certificate, and identification documents of your authorized representatives. While specific requirements may vary slightly depending on your business structure, here’s what’s typically required for local corporations and partnerships:
- BIR Form 1903 (Application for Registration for Corporations/Partnerships).
- SEC Certificate of Registration.
- Articles of Incorporation and By-laws.
- Lease contract or proof of business address.
- Valid government-issued IDs of company officers or authorized representatives.
- Taxpayer Identification Number (TIN) for each incorporator/partner.
For foreign-owned corporations, you will also need:
- Proof of inward remittance or capital infusion (if applicable).
- Foreign Investment Certificate from relevant agencies (e.g., BOI, PEZA, SEC, depending on your setup).
- Passport and Alien Employment Permit (AEP) of foreign directors (if applicable).
- Board resolution designating authorized representatives.
Since RMC 57-2020, the mayor's permit is no longer a prerequisite for COR, and the BIR accepts registrations while it is still in process.
If you are a sole proprietor, freelancer, or a certified professional, the requirements for obtaining BIR COR are as follows:
- Accomplished BIR Form 1901
- Any government-issued ID showing your name, address, and birthdate
- DTI Certificate of Business Name, if you trade under a name other than your own
- PRC license, for licensed professionals
- Proof of address, such as a lease contract or proof of property ownership
Step-by-Step BIR COR Application Process
The tax registration process can be challenging if you try to handle it on your own, risking delays or rejections. Emerhub experts guide you through each step, ensuring all documentation is accurate to help secure timely approvals.
The following are the steps to secure a BIR Certificate of Registration:
1. Prepare the Required Documents
To apply for BIR COR, the first step is to prepare your essential documents as mentioned above. It is crucial to ensure that your business name, address, and other key details across all documents (SEC registration, proof of address) exactly match the information you submit to the BIR.
Our experts will handle the preparation and review all documents, ensuring accuracy and consistency with your business permits and planned activities.
2. Filing with the Correct BIR Revenue District Office (RDO)
Your application must be filed at the specific RDO that has jurisdiction over your business address. If you’re not physically in the Philippines, Emerhub acts as your authorized representative to ensure smooth coordination with the BIR on your behalf.
3. Attend the BIR Taxpayer Initial Briefing
If your assigned RDO requires attendance at a taxpayer briefing, we’ll assist with coordinating the process to ensure the requirements are met. This includes attending the briefing as your representative or advising you on the next step.
4. Claim the Certificate of Registration (Form 2303)
Upon approval, we’ll collect your COR (Form 2303) and secure any related documentation, including the Authority to Print (ATP) for official receipts or invoices and the Notice to Issue Receipts or Invoices (NIRI).
5. Post-Registration Compliance
After receiving your COR, maintaining compliance with BIR regulations is an ongoing responsibility. Emerhub can help you manage these crucial post-registration tasks:
- Registering and declaring your chosen Book of Accounts (manual, loose-leaf, or computerized). Each method has its registration process, which must be approved by the BIR.
- Work with BIR-accredited printers to secure your Authority to Print (ATP) for official receipts and invoices.
- Setting up your tax filing schedule based on your registered tax types
- Helping you maintain proper accounting records aligned with BIR requirements
A key aspect worth mentioning here is that if your registered name, address, or line of business change, you must file BIR Form 1905 to update it. Similarly a move to another district transfers the registration to the new RDO.
Leaving the certificate outdated causes problems with aspects such as your invoicing, business permits, and even audits. Therefore, treat updates as important part of running the business.
Common Mistakes to Avoid During BIR COR Registration
As a foreign business owner, getting the details right from the start can save you from significant delays and penalties. Here are some of the common pitfalls to watch out for:
- Invalid Virtual Office Address: Some BIR RDOs reject registrations with addresses that cannot support a physical inspection. Therefore, if you are using a virtual office service, ensure it's the one that meets SEC and BIR requirements. Emerhub offers a compliant virtual office solution if needed.
- Incomplete or Inconsistent Documents: Any discrepancies in address or business name between your SEC documents, lease agreements, and permits can cause delays. So, ensure all the details are correct and consistent across the documents.
- Skipping the Taxpayer Briefing: Some RDOs require an initial briefing before releasing the COR.
- Delaying Official Receipts Setup: Without official receipts or invoices, you can’t legally transact or claim certain business expenses.
- Unregistered Book of Accounts: Failure to register your books can lead to compliance issues during audits and may result in denied expense deductions.
Emerhub is here to assist you throughout the entire BIR COR registration process, helping you avoid these common mistakes and ensuring your business remains compliant.

Frequently asked questions
How long is the BIR COR valid for?
The BIR Certificate of Registration (COR) does not have an expiration date. However, businesses are required to pay an annual registration fee and comply with ongoing tax obligations to keep their registration active.
Can a foreigner directly apply for a COR?
Yes, foreigners can register a business and apply for a BIR COR in the Philippines, either as individuals or through a corporation. If the applicant is not physically present in the country, it is standard practice to appoint a local representative via a Special Power of Attorney (SPA) to process the application on their behalf. This is a common requirement for various government transactions involving foreign nationals.
Can I apply for a COR if I don’t have a Mayor’s Permit yet?
Yes. In practice, most BIR Revenue District Offices (RDOs) accept proof that you have applied for a Mayor’s Permit when registering a business and applying for a COR. However, requirements may vary by RDO, and some may insist on the actual Mayor’s Permit before processing the application.
What is the Notice to Issue Receipt/Invoice (NIRI)?
The NIRI is a notice released with your COR that tells customers your business is registered and must issue an invoice for every sale. Physical shops post it where customers can see it, and online sellers place it on their store page next to the COR. Tax mapping teams check for it during visits, and a missing notice draws a compromise penalty on the spot.
What does COR mean in BIR?
COR stands for Certificate of Registration, the document the BIR issues as proof that a business or professional is registered in the Philippine tax system. The official name is BIR Form 2303. Both terms refer to the same document.
Is the BIR COR the same as a business permit?
The COR is your national tax registration with the BIR. The business permit, often called the mayor's permit, is a separate local government requirement. A compliant business holds both, along with its SEC or DTI registration.
What happens if I operate without a COR?
Operating an unregistered business violates the tax code and carries fines that start at PHP 5,000 and can reach PHP 20,000, on top of the taxes and surcharges the BIR assesses once it finds you. Unregistered sellers increasingly get caught through platform reporting and third-party data. Registering late also means clearing every return you should have been filing all along, so registering before you start is the cheaper path.
