In the Philippine tax administration system, the Bureau of Internal Revenue (BIR) maintains jurisdictional authority over taxpayers through Revenue District Offices (RDOs). A common procedural question arises when a taxpayer undergoes a change of business address or residence—necessitating a transfer of registration to a new RDO—while simultaneously being subject to an ongoing audit under a valid Letter of Authority (LOA).

The General Rule: Continuity of Audit Jurisdiction

Under existing BIR regulations, including Revenue Regulations (RR) No. 7-2012 and subsequent circulars governing the transfer of registration, the transfer of an RDO does not automatically terminate or nullify a pending audit or investigation.

When a Letter of Authority is issued, it grants the specific revenue officers named therein the authority to examine the books of accounts and other accounting records of the taxpayer for a specific taxable period. This authority is attached to the taxpayer's liability for that period, rather than being strictly tethered to the geographic location of the RDO.

Procedural Mechanics of Transferring RDOs

When a taxpayer initiates a transfer of registration (using BIR Form No. 1905), the BIR follows a protocol to ensure that pending tax liabilities are not abandoned:

Notification: The taxpayer must file the application for transfer with the current RDO (the "old" RDO).
Clearance: The old RDO typically conducts an internal verification to determine if there are any outstanding "open" cases, including pending audits under an LOA.
Transfer of Records: If an audit is pending, the transfer process involves the formal turnover of the investigation records from the old RDO to the new RDO, or the continuation of the audit by the old RDO until the assessment process is concluded, depending on the stage of the audit.

Can the Transfer be Blocked?

While a taxpayer has the legal right to change their registration address, the BIR generally imposes a "hold" on the transfer of electronic records within the Integrated Tax System (ITS) if an active LOA exists.

Administrative Hold: The system often prevents the final transfer of the taxpayer's registration until the pending audit is settled, an assessment is issued, or the case is otherwise closed.
The "Transfer Pending Investigation" Rule: The BIR may allow the transfer of registration for current/future transactions but will legally require that the investigation for the period covered by the LOA be finalized by the original investigating office. This ensures that the revenue officers who commenced the audit can conclude their findings without jurisdictional disputes.

Legal Implications for the Taxpayer

For taxpayers in this situation, the following legal principles apply:

No Immunity: A change in RDO cannot be used as a procedural shield to evade, delay, or interrupt an ongoing tax audit. Any attempt to interpret a change of venue as a basis to invalidate an LOA is inconsistent with the BIR’s mandate to assess and collect taxes.
Continued Compliance: The taxpayer remains obligated to cooperate with the revenue officers assigned under the original LOA. Failure to present records to the original investigating team because of a change in RDO may be construed as a failure to comply with a lawful summons, potentially leading to administrative or criminal charges under the National Internal Revenue Code (NIRC).
Jurisdictional Continuity: Revenue officers who issued the LOA maintain the authority to finish the audit unless the Commissioner of Internal Revenue or the authorized official officially reassigns the case to the new RDO via a new Letter of Authority or a memorandum of reassignment.

Conclusion

In the Philippine context, the transfer of an RDO is a change in the administrative "home" of the taxpayer's registration, but it does not supersede the authority granted by an existing LOA. Taxpayers should anticipate that the BIR will require the finalization of any pending audit as a condition precedent to the successful completion of an RDO transfer, or they should expect the audit to follow them—or remain with the original investigators—until its final resolution.

It is strongly advised that taxpayers coordinate closely with the Collection and Audit Divisions of their current RDO before finalizing a transfer to avoid administrative delays or potential charges of non-compliance.
