How to register to BIR Online Registration and Update System (ORUS) for Corporations

What is ORUS?

Online Registration and Update System or ORUS is a web-based system of the Bureau of Internal Revenue (BIR) that provides an end-to-end process for registration of taxpayers and updating of their registration information.

We understand the importance of ensuring compliance with tax regulations while minimizing the hassle for you and your business. That's why we're here to guide you through the easy steps of registering with ORUS. Let's dive into this practical guide to BIR ORUS registration for corporations.

Key Requirements for Registration

To ensure a smooth registration process, corporations must prepare the following documents:

  1. BIR S1905 Form or the Registration Update Sheet - This form is essential for updating taxpayer information, including changes in business details, contact number and address.

  2. Special Power of Attorney (SPA) or Secretary's Certificate - This document authorizes the representative indicated in Form S1905 to act on behalf of the corporation in matters related to tax registration.

  3. Valid IDs - Both the individual named in S1905 Form and the Corporate Secretary must present valid identification cards. These IDs should clearly display the signatures of the respective individuals.

Step-by-step Guide to Registration for Corporations

Step 1. Secure and Fill-out the BIR S1905 Form. Before initiating the registration process on ORUS, corporations must fill-up the BIR Form S1905, which serves as the application for registration information update. This form will be available at your BIR Revenue District Office (RDO). You can also download it from the BIR website or through this link. Together with this form, corporations should also prepare for the SPA or Secretary’s Certificate and Valid IDs. 

Step 2. Submit the BIR S1905 Form together with the SPA or Secretary’s Certificate and Valid IDs to the designated BIR RDO where your company is registered. Once submitted and verified by the RDO, you will receive a copy of the form with a stamp that your records have been updated. You will also receive an email confirmation in your registered email address indicated in the form that your registration information has been successfully updated. 

Step 3. Complete your ORUS Registration. To begin your registration, proceed to the BIR ORUS website. Within the ORUS platform, the authorized representative must input the required information accurately, following the prompts provided. Remember that the email address you will have to input for ORUS registration should be the registered email address you entered in the BIR S1905 Form.

Step 4. ORUS Account Verification. After registration, you will receive a system-generated email in your registered email address. Take note, that you will only have 24 hours to verify your account. Failure to verify your account within the 24-hour period will result in unsuccessful registration and you will have to restart the registration process again.

Additionally, if the details you provided during registration don't match the records at the BIR, your registration won't go through. In this case, you'll need to visit your RDO to submit an updated S1905 form again.

Step 5. Congratulations! You’ve successfully registered in the BIR ORUS! Once your ORUS Account has been successfully registered and verified, a one-time password (OTP) shall be sent to your registered email address for every transaction done in the system.

The use of ORUS is expected to eliminate manual paperwork and physical visits to the BIR which will save you time and resources, enabling you to focus more on managing your business.
