RMC No. 55-2026: Every tax return tells a story

Not judging a book by its cover is surely an overused piece of advice, but its wisdom endures. Readers will know that a book’s essence is not found on its cover. The details woven throughout its pages are what bring the story to life.

The same principle applies to tax compliance. It’s the supporting details that provide meaning and credibility to what is ultimately reported to the tax authorities.

In this context, Revenue Memorandum Circular (RMC) No. 55-2026 serves as a timely reminder that the supporting details, particularly the submission of alphalists, remain an integral part of the story.

OVERVIEW OF RMC NO. 55-2026
On May 26, the Bureau of Internal Revenue (BIR) issued RMC No. 55-2026, reiterating the obligation of the withholding agents to submit the Alphabetical List of Employees/Payees from Whom Taxes Were Withheld (alphalist) to the BIR on or before the following due dates:

10^th day of the following month

BIR Form 1600-PT

BIR Form 1600-VT

Last day of the month following the close of the taxable quarter

BIR Form 1601EQ

BIR Form 1601FQ

BIR Form 1603Q

Jan. 31 of the succeeding year

BIR Form 1604C

BIR Form 1604F

March 1 of the succeeding year

BIR Form 1604E

In summary, the due date for the submission of the alphalist falls on the same date as the filing deadline for the abovementioned tax returns.

DEFINITION OF WITHHOLDING AGENT
The Tax Code, as amended, defines “withholding agent” as any person or entity having control over payment of income and required to withhold tax.

Several issuances have likewise identified entities considered withholding agents, including Revenue Regulations (RR) No. 16-2023, as subsequently amended by RR No. 5-2025. Under these regulations, electronic marketplace operators and digital financial services providers are considered withholding agents and are required to withhold and remit to the BIR one-half percent (1/2%) of their gross remittances to sellers or merchants for goods or services transacted through their platform or facility.

MODES OF ALPHALIST SUBMISSION
Under RR No. 1-2014, as clarified by RMC No. 5-2014, withholding agents shall submit the alphalist:

•  As an attachment in the Electronic Filing and Payment System (eFPS);

• Through Electronic Submission (eSubmission) using the BIR’s website address at (esubmission@bir.gov.ph); or

• Through Electronic Mail (e-mail) submission at dedicated BIR e-mail addresses using the data entry module of the BIR.

Prior to submission, withholding agents are likewise required to validate the alphalist using the Alphalist Data Entry and Validation Module, which is available for download from the BIR website.

PENALTIES FOR NON-SUBMISSION
The alphalist forms an integral part of the withholding tax return, and as such, its submission constitutes a core obligation of the withholding agent. Non-compliance is not merely procedural, but it also carries measurable consequences.

Failure to submit the alphalist or to provide complete and accurate information, constitutes non-compliance and is subject to penalties under Revenue Memorandum Order (RMO) No. 7-2015. A penalty of P1,000 is imposed for each failure to file, submit, or supply the required information return, provided that the aggregate amount to be imposed during a calendar year does not exceed P25,000.

Moreover, under RMO No. 7-2015, the following violations are considered willful failure or neglect tantamount to fraud, and therefore cannot be compromised under the existing rules and regulations:

• Failure to submit the annual alphalist of payees for at least two consecutive years; or

• Non-submission in the format prescribed.

Taxpayers are reminded that the submission of incomplete, inaccurate, or erroneous lists may be deemed non-submission. Likewise, the submission of falsified information is regarded as an act of fraud, which cannot be settled through compromise penalties, and may expose taxpayers to more severe consequences.

The BIR may issue and enforce Subpoena Duces Tecum (SDT) requiring taxpayers to provide documents and records, and failure to comply with the SDT may result in criminal charges and penalties not less than P5,000 but not more than P10,000 and suffer imprisonment of not less than one year but not more than two years (Section 266 of the NIRC, as amended).

SUBMISSION OF OTHER ATTACHMENTS
While the following are not specifically covered by RMC No. 55‑2026, taxpayers are expected to ensure compliance with all related attachments required under recurring reporting requirements.

In particular, RR No. 16-2005, as amended, requires the submission of Summary Lists of Sales and Purchases (SLSP) as an attachment to the Quarterly VAT (BIR Form 2550Q). These must be submitted on or before the 25^th day following the close of the taxable quarter. However, taxpayers under the jurisdiction of the Large Taxpayer Services (LTS), and those enrolled under the eFPS have an extended deadline to submit the SLSP — on or before the 30^th day following the close of the taxable quarter.

In addition, RR No. 2-2006, as amended, requires the submission of the Summary Alphalist of Withholding Taxes (SAWT) as an attachment to the relevant tax returns in instances when the taxpayer claims tax credit supported by BIR Form 2307 in their income tax and VAT returns.

IMPORTANCE OF ALPHALISTS
Although the submission of alphalists is often viewed as an additional compliance requirement, their role in tax compliance remains significant. The alphalist provides a detailed breakdown of the taxes withheld and remitted, enabling BIR to perform data matching and cross checking to verify the accuracy of tax payments, especially during assessments. Given this, taxpayers should ensure that the information reported in their alphalists is complete, accurate, and properly reconciled with the taxes remitted, as any discrepancies may give rise to potential compliance issues.

The continuing emphasis on alphalist submissions reflects the BIR’s effort in information matching as part of its assessment process. As BIR increasingly leverages technology to validate transactions, the quality and consistency of taxpayer data have become just as important as the timely filing of the corresponding tax returns.

However, maintaining an alphalist is not without challenges. Taxpayers are required to consolidate information, reconcile discrepancies between books and returns, and ensure that information and other details are reported accurately. Along with this, missing or inaccurate information at the time of submission may expose taxpayers to penalties under RMO No. 7-2015. As the BIR continues to strengthen its data-matching capabilities, accurate alphalist records have become increasingly important.

These challenges are further compounded by system limitations. Taxpayers encounter delays, or, in some cases, the absence of e-mail validation confirmations following the alphalist submission. As these confirmations serve as proof of receipt by the BIR and are commonly requested during tax assessments, the lack of timely validation adds another layer of exposure to the taxpayer.

At its core, RMC No. 55-2026 is not merely about submission deadlines but rather serves as a timely reminder that both withholding agents and the BIR play important roles in this story telling. While taxpayers are expected to meet timely and accurate reporting, there is likewise a need for the BIR to enhance its systems and processes to support a more efficient compliance. Only when both sides fulfill their roles can the story unfold as intended: with clarity, completeness, and fewer unexpected plot twists along the way.
