How to Update Your BIR Registration When Your Business Information Changes in 2026

A business can remain the same taxpayer while its registration information changes. A new address, new contact details, additional business activity, changed trade name, transfer to another Revenue District Office (RDO), or other change can require the BIR registration record to be updated.

The important point is simple: do not treat your BIR registration record as a one-time filing that can be ignored after the Certificate of Registration is issued. The BIR provides registration-update mechanisms precisely because taxpayer information can change during the life of a business.

This 2026 guide explains what commonly needs to be updated, when ORUS can be used, when supporting documents may be required, and what to check before submitting a change.

Start with the question: does the information currently held by the BIR still accurately describe the taxpayer and the business?

Common situations include:

The BIR's current registration-update checklist specifically identifies several information updates that may be performed through ORUS, including contact information, contact person, civil status, residence address, transfer of registration record, additional line of business, new business name, new tax types/form types, and the 8% income-tax-rate option.¹

For many taxpayer registration updates, the BIR's Online Registration and Update System (ORUS) is the practical starting point.

The BIR describes ORUS as the online system that facilitates the end-to-end process of taxpayer registration and updating of information.

The current ORUS workflow for an existing taxpayer generally begins by logging in, selecting Update Information, then selecting Correction/Change/Update of Registration and proceeding to the relevant update function.²

This does not mean that every possible change can be completed in exactly the same way. The available transaction, validation requirements, supporting documents, and whether an RDO transaction is still necessary depend on the type of change and the taxpayer's circumstances.

If the taxpayer's contact details are outdated, they should not simply be left unchanged because the business itself has not moved.

Email addresses, mobile numbers, and contact-person details can affect how the taxpayer receives communications and completes BIR electronic transactions. Keeping these details current is therefore part of maintaining an accurate registration record.

An address change can be more significant than changing a phone number because it may affect the taxpayer's registration record and the RDO responsible for the taxpayer.

The BIR's registration-update materials expressly include change of residence address and transfer of registration record among updates available through ORUS.¹ Where the change involves a business establishment, branch, or other registration circumstance, additional documentary requirements may apply.

The BIR's registration rules treat place of registration and transfer of registration as specific registration matters rather than merely administrative profile changes.³

Before submitting an address change, check the actual business address, supporting local registration documents, branch information if applicable, and the RDO implications of the move.

A business may start with one activity and later add another. For example, a retail business may begin offering a separate service, or a professional practice may add another revenue-generating activity.

Do not assume that changing the description on a website, social-media page, invoice, or business permit automatically updates the BIR record.

The BIR's registration-update checklist expressly includes adding an additional line of business through ORUS, while other changes in registered activities or business names may require supporting documents depending on the transaction.¹

A change in the registered name or trade name is more than a cosmetic edit. The BIR may require evidence of the underlying change from the agency that issued the relevant primary registration or permit.

For example, the BIR's documentary requirements identify an amended SEC certificate, DTI certificate, or other applicable supporting document for certain changes in registered name, trade name, or registered activities.¹

This is why a business should coordinate the sequence of its registration changes instead of updating one government record while leaving the others inconsistent.

The BIR also provides a process for updating taxpayer classification through ORUS.

Revenue Memorandum Circular No. 113-2024 announced the availability of the Update of Taxpayer Classification functionality and described the ORUS route for taxpayers seeking to update their classification.⁴ The classification framework under the Ease of Paying Taxes Act uses annual gross sales thresholds for micro, small, medium, and large taxpayers.

The practical lesson is that taxpayer classification is not something a business should guess from its size or number of employees. Use the applicable BIR rules and current transaction guidance when determining the classification to request.

Yes—but the correct transaction channel matters.

The BIR's registration-update materials continue to identify BIR Form No. 1905 for certain registration information updates and documentary transactions.¹ At the same time, the BIR has moved a number of registration-update functions into ORUS.

That means “use Form 1905” is no longer a sufficient answer to every BIR registration-update question. The first step should be to identify the exact change and check whether the current ORUS workflow covers it, whether the transaction requires supporting documents, and whether an RDO submission remains necessary.

For taxpayers using electronic systems, this distinction can prevent unnecessary trips to an RDO while also avoiding the opposite mistake of assuming that every change is completely online.

The exact documentary requirements depend on the change. A useful preparation set is:

The BIR's documentary-requirements checklist emphasizes that processing commences only after complete documents are submitted and that incomplete requirements may be returned or not processed.¹

Do not begin with a generic “BIR update.” Write down the specific information that changed and when it changed.

If the change originated with DTI, SEC, an LGU, or another regulator, confirm that the supporting record is already correct or determine the proper sequence for the related updates.

Log in to ORUS and review the available Update Information and Correction/Change/Update of Registration functions.

Use the current BIR checklist for the exact transaction. Do not rely on an old checklist simply because the transaction has the same name.

Complete the ORUS transaction when available. If the transaction requires an RDO submission, appointment, supporting document, or another BIR process, follow that requirement instead of assuming the online workflow replaces it.

Keep the transaction confirmation, updated registration documents, and supporting records with the business's compliance files. The goal is not merely to submit an update; it is to make sure the registration record actually reflects the business after the change.

Updating only one agency. A change in business information can affect DTI or SEC records, LGU permits, BIR registration, and industry-specific licenses. Updating one record does not automatically update the others.

Using an outdated checklist. BIR registration processes have changed substantially with the EOPT reforms and the expansion of ORUS. Always verify the current transaction requirements before filing.²

Assuming every change is online. ORUS covers many updates, but the exact transaction and supporting requirements determine whether additional RDO action is needed.

Changing business activities without checking registration implications. Adding a new activity may affect tax types, permits, licenses, invoicing, and other compliance obligations.

Keeping an outdated email or contact number. Registration information should remain usable for taxpayer communications and electronic transactions.

A simple contact-information correction may be straightforward. More complicated situations can involve several records at once—for example, an address transfer combined with a new line of business, a registered-name change, additional branch activity, or a change that affects tax types.

In those cases, the useful question is not simply “How do I change my BIR record?” It is “What other registrations and permits must change at the same time, and in what order?”
