BIR Form S1905 is the Registration Update Sheet used to update taxpayer registration details and support account enrollment in the Online Registration and Update System (ORUS). The August 2022 form says to send it with applicable supporting documents to the Revenue District Office (RDO) where the taxpayer is registered; it allows email submission. For an individual filing without a representative, the sending email must match the taxpayer’s designated official email entered on the form.
What Form S1905 is for
The Bureau of Internal Revenue (BIR) titled its August 2022 form “Registration Update Sheet.” It is intended both “For Account Enrollment in Online Registration and Update System” and “For Updating of Records Required in Taxpayer Registration System.” Revenue Memorandum Circular (RMC) 122-2022, dated August 18, 2022 and issued August 22, 2022, directed taxpayers intending to use ORUS—and taxpayers then handling registration matters manually—to update registration information such as email and contact details using the sheet. Read RMC 122-2022.
ORUS is BIR’s online service for registration and information updates. S1905 is a registration-record update form, not a tax return. BIR’s description of ORUS is available on its ORUS page.
What information the sheet requests
Complete the fields relevant to the taxpayer and the update. The form asks for identifying, contact, and registration details, with additional information for individuals and for non-individual taxpayers using a representative.

| Section | Information requested |

The official email field is for the registered taxpayer’s own official address—not a representative’s or tax agent’s address. The form says BIR will use it for orders, notices, letters, and other communications. The declaration begins: “I declare, under the penalties of perjury, that this application has been made in good faith, verified by me and to the best of my knowledge and belief, is true and correct, pursuant to the provisions of the National Internal Revenue Code, as amended, and the regulations issued under authority thereof.” View the S1905 form.
How to complete and submit Form S1905
- Get the form and enter the details being updated. Use the BIR’s August 2022 S1905. Print the information to be updated, as the form instructs, and complete the applicable fields.
- Gather the supporting documents that apply. The form’s checklist names a government ID for the individual taxpayer or a birth certificate; a marriage certificate; and, when a representative transacts, an SPA or Board Resolution/Secretary’s Certificate, together with government IDs for the signatory and representative. Requirements can depend on the transaction, so confirm the current checklist with the registered RDO.
- Sign and date the declaration. The taxpayer or authorized signatory should complete the declaration required by the form.
- Send the completed sheet and scanned or photocopied supporting documents to the registered RDO. The form says email submission is available. An individual who is not filing through a representative must send the email from the same address entered as the taxpayer’s designated official email.
For taxpayers with branches, RMC 122-2022 says to update the head-office registration first, before updating branch records. It also directs employers to inform employees of the requirement. Check with the RDO for current transaction-specific instructions before submitting.

Email to the RDO or TRRA: which route applies?
BIR’s Taxpayer Registration-Related Application (TRRA) portal lists “Updating of Email Address using Application Sheet Form S1905” among its registration-related applications. The portal describes electronic submission of scanned PDF documents and email routing to the concerned RDO. RMC 120-2023 also says that applicants who need an email update for a Digital TIN ID application may submit S1905 by email to their RDO or through TRRA.
| Route | Documented use | What to keep in mind |
|---|---|---|
| Email to the registered RDO | The S1905 form says the sheet may be emailed to the RDO where the taxpayer is registered. | For an individual filing without a representative, send from the designated official email entered on the form. |
| TRRA portal | TRRA lists S1905 for updating an email address. RMC 120-2023 identifies email or TRRA submission for email updates needed in the Digital TIN ID process. | This supports the route for the listed email-update use and that specific Digital TIN ID context; it does not establish that TRRA is the route for every S1905 update. |
Check the live TRRA portal and the RDO’s current instructions for the transaction you are filing. Later BIR guidance confirms electronic routes in specific contexts, not a universal channel for every field or update. RMC 120-2023.
