BIR Certificate of Registration Guide: What is Form 2303 and Why Do You Need It?

Whether you’re a freelancer or a business owner, obtaining a BIR registration certificate is a must for you.

Also known as BIR Form 2303 and Certificate of Registration (COR), this type of document gives you the legal rights to operate your business in the Philippines. All professionals licensed by the Philippine Regulatory Commission, Non-Licensed Professionals like freelancers and people with digital careers, sole proprietors, partnerships, corporations and cooperatives should have this sheet of paper, and should take care of it.

It provides you with Tax Identification Number (TIN) for your business, if you are a partnership, corporation or a cooperative. If you are a professional or a sole proprietor, your personal TIN is the one indicated in the Certificate of Registration. It also states the types of taxes you will settle.

Here is a sample of a Certificate of Registration and its parts:

Sample Certificate of Registration

Many business owners are hesitant to register their ventures because the process can be expensive and time-consuming. But having a legitimate business is beneficial to your company and its growth.

Some people also think that once one registers, the BIR will know that they exist. But, in reality, once a Client withholds taxes and gives you a 2307 form or a Certificate of Creditable Tax Withheld at Source, BIR already expects you to pay taxes as a business. To know more about 2307 forms, check this link:

Helps build customer’s trust

Consumers tend to buy products from credible and trustworthy brands. And having a COR can help you gain your customer’s trust.

Say you’re running a coffee shop. When your business is registered, you are required to display the certificate and other forms in your establishment, such as the Mayor’s Permit, Sanitary Permit, Health Clearance, and Fire and Safety Inspection Certificate. These documents have the power to make your customers feel safe. They will be more confident to purchase your goods and recommend your establishment. This gives you the chance to attract more customers and gain more profit.

Gives you marketing advantage

When your business is legitimate, you’ll be more confident to market it, especially online. And in this digital age, being visible on the internet can give you a competitive advantage.

You can build your business website and set up marketing campaigns on different social media platforms without worrying about legal issues. This will boost your sales and give you the opportunity to recover the costs of your taxes.

Clients usually have a vendor accreditation process where they will require you to submit your COR (Form 2303) and other documents. Clients need these to be able to vet that you are a legit business and that they will be able to get an official receipt from you which they will need to log payment to you in their books. Remember that those who can issue official receipts catch the bigger clients!

Gives you a peace of mind

As an entrepreneur, there are several things in your mind. You think about your marketing strategy, your sales, and maintaining your business.

Securing a BIR registration certificate will give you one less thing to worry about. Remember, you can make your business invisible in the government’s records by not filing a Form 2303, but it doesn’t make you safe in the eyes of their inspectors.

Also, there are punishments for those who don’t register their businesses. When caught, you will have to pay a fine of P5,000 to P20,000 and serve 6 months to 2 years in prison.

Filing for a BIR Certificate of Registration can be time-consuming, but a business license is vital to your success. Besides, you have to know your obligations as an entrepreneur. Keep in mind that it’s wise to comply with the laws and regulations because it lets you focus on running and growing your business.

  1. Good evening Sir /Madam, pag ang bir form 2303 line of business is wholesaling anong meaning niya. At paano malaman ang meaning ng mga line items n hindi nka elaborate.

    Salamat po

    1. You have to pay a registration/renewal fee annually. BUT you don’t get a new COR/Form 2303. πŸ™‚ You just make sure you keep your receipt/payment record.

        1. Hi Sheryl, not exactly sure what you mean by census, pero kailangan na may TIN ang lahat ng employed. Kung fully employed naman (at hindi independent contractor), TIN lang ang kailangan. πŸ™‚

        2. ok lang po ba na after cor mag file for business permit without physical store like sa online lang na wholesale, nasa house lang ang bodega

          1. Hi Luanne! Since Mayor’s Permit is no longer a requirement to register a Sole Prop business with the BIR, yes you may do so. Though you need to register with your Local Government Unit as soon as you are done with your BIR registration so that you avoid paying penalties. Sharing with you these video playlist to know more about taxation and business registration as an online seller.

            If you need further assistance just let us know. Thank you!

      1. Hi! I read your blog, and it is very helpful. I have a question tho. I transferred from one RDO to another. Do I need to obtain a new COR from the new RDO or not necessarily? Thank you!

  2. Hi Taxumo, I have office and workshop where my fabrication is being done. They are in different place but within the same RDO. My question is Do I still need to Register my my Workshop. We lines of business is equipment fabrication.

    1. Hi Carl, the safe answer is YES, get your office registered as the head office and your workshop as a branch. The reason is it makes sense for both to be registered because business is conducted in both venues. For the workshop, for example, the LGU will need to make sure the proper permits (fire, etc) are in place.

      Don’t worry – in such a case, tax compliance is normally “consolidated” naman under the head office so it doesn’t make tax compliance more difficult. πŸ™‚

  3. When registering yourself as a business, is there any additional requirement if your source of funds is from a different country? (i.e. online freelancer that provides administrative services to a business registered in the USA.

    1. Hi Kryss, nope! Process is completely the same. Some officers taking in your application are confused by what we do (internet ano?) so it’s possible that they might ask to see a contract. Otherwise, feel free to simplify what you do in “offline” terms — e.g. you do digital marketing (fb/seo/sem), just say you’re doing marketing consultancy. Doing some freelance seo writing, just say you’re a writer. πŸ™‚

    2. Hi sir,pag ma utang na pa sa bir at kumuha ng panibagong business pirmit,kailangan po b na bayaran munayong utang bago ma isyohanng bagong permit?

  4. hi taxumo! I am a real estate broker and a freelancer, I have my COR for real estate broker, now my freelance client Manila vendor is asking for a COR software development, BIR told me I can update my COR, but I guess I don’t need to update it because I am still into real estate, can I register for a 2nd business for freelancer? how about the OR? Do I need to use the same OR for both real estate and freelancer? Or I need to request for ATP to print another OR specifically for freelancer? Thank you for your answer

    1. First of all – love the hustle! Go go go!
      With respect to your COR, you can go about it in 2 ways. First, you can get a new COR. That COR is going to be a branch, so tax wise, everything’s consolidated under the main branch. In other words, not that much more complicated esp if you’re using Taxumo. πŸ˜‰ Second, you can also update your existing COR to include a new industry. For this option though, your mileage may vary a bit — some RDO officers are okay with this, while some will convince you to get a new one altogether. Important that you know that this is an option though so you can ask them about it when the discussion comes up. Good luck!

        1. I believe you’ll need a separate set of OR booklets for the branch. πŸ™‚ Likely though, di mo sya magagamit — ok lang yon. What’s important naman is that you report your income.

      1. My new business was a trading which lines are agricultural products raw logs,food processing like peanutbutter, atchara and soya beans taho and tokwa . My resources are from Cooperatives and NGO with livelihood programs I am applying for BIR Registration. Was it non vat or vat oriented?

  5. Good pm, Sir.

    For updates made in the certificate of registration, like adding a new line of business, the COR shows date updated: 12 23 2019, is it safe to conclude that said date are both the effectivity and issuance date?

    Thank you.

  9. Hello. In our BIR 2303, it states that among our registered activities is WITHHOLDING TAX – FINAL but I never filed any return for that because we do not have any final tax withheld or any transaction subject to that. My question is, is it okay not to file 0619F and 1601FQ or should I have filed zero returns for final withholding tax because it is among our registered acitivities?

  10. Hi Taxumo

    I already have an existing TIN number as an employee for a company, I’m also a health insurance agent on the side and they are requiring that I get a COR 2303, which BIR form should I use to register?

    Thank you.

  18. Hello, may I ask how can you market your professional services if you are registered in BIR as a professional? Can you use a “brand name” instead of your full name? Given that you are not registered as a sole prop with a trade name.

  19. We are a US based firm that will be contracting with an entity in the Philippines. We do not have nor will we be establishing an office in the Philippines. We have a TAX clearance already. Can you please confirm that the COR is only if you are establishing an office/address in the Philippines. All our work will be done remotely or through travel on-site.
