Revenue Memorandum Order (RMO): BIR Internal Directives
Updated June 13, 2026
On this page
Definition
A Revenue Memorandum Order (RMO) is an issuance of the Commissioner of Internal Revenue that sets policies, procedures and guidelines for BIR personnel on how to implement existing tax laws and regulations, such as audit procedures, processing rules and penalty schedules.
Revenue Memorandum Orders are the BIR's main tool for directing its own offices on procedures and the application of existing rules, without changing the law. They standardize how returns are processed, how audits are conducted and how penalties are compromised. They differ from Revenue Regulations, which the Secretary of Finance promulgates upon the Commissioner's recommendation to implement the Tax Code (NIRC Sec. 244), and from Revenue Memorandum Circulars, which publish and clarify rules for taxpayers. RMOs help ensure uniform application of tax laws across BIR offices, and tax practitioners read them to understand how examiners will handle a given issue.
Detailed explanation
What is a Revenue Memorandum Order?
A Revenue Memorandum Order (RMO) is an official issuance of the Bureau of Internal Revenue (BIR) that communicates internal policies, procedures and guidelines to BIR personnel on applying existing tax laws and regulations. RMOs are not legislation; they are administrative instruments used to keep the application of the National Internal Revenue Code (NIRC) consistent across BIR offices and revenue districts.
Legal Basis and Authority
The Commissioner of Internal Revenue has the power to interpret the Tax Code, subject to review by the Secretary of Finance (NIRC Sec. 4), and may delegate powers to subordinate officials under rules set by the Secretary (Sec. 7). RMOs are issued under these powers and bind BIR personnel. Revenue Regulations, by contrast, are promulgated by the Secretary of Finance upon the Commissioner's recommendation (Sec. 244).
Types and Content of RMOs
RMOs cover topics such as:
- Audit and examination procedures: Programs and steps examiners follow.
- Processing guidelines: Handling of registrations, applications, refund claims and certificates.
- Implementation directives: How BIR offices apply new laws and regulations, such as the TRAIN Law (RA 10963).
- Penalty schedules: For example, RMO 7-2015's schedule of compromise penalties.
- Organizational matters: Assignment of functions among BIR offices.
Distinction from Other BIR Issuances
The BIR issues several types of guidance documents. RMOs differ from Revenue Regulations (RRs), which are implementing rules promulgated by the Secretary of Finance (NIRC Sec. 244) and set things like withholding rates. RMOs are also distinct from Revenue Memorandum Circulars (RMCs), which publish and clarify rules for taxpayers, and from rulings, which answer specific taxpayer requests. Each has its own scope and weight.
Applicability to Taxpayers
RMOs are addressed to BIR personnel but are published on the BIR website, and taxpayers use them to understand how their returns, applications and audits will be handled. Under NIRC Sec. 246, a revocation, modification or reversal of BIR rules, rulings or circulars is not applied retroactively if it would prejudice taxpayers, except where the taxpayer misstated or omitted material facts, the facts later gathered are materially different, or the taxpayer acted in bad faith. RMOs do not override the NIRC or Revenue Regulations; if they conflict, the higher-order rule prevails.
Examples of RMOs
A frequently used example is RMO 7-2015, which sets the schedule of compromise penalties for non-fraud criminal violations of the Tax Code. RMOs are cited by number and year, for example "RMO No. 7-2015", and are archived on the BIR website.
How to Access and Use RMOs
Taxpayers and tax professionals can find RMOs on the BIR website (www.bir.gov.ph) and in tax reference databases. When responding to BIR notices, it helps to cite the applicable law, regulation and order. If an RMO is unclear in your situation, you may ask your Revenue District Office or request a ruling from the BIR.
Why it matters
RMOs show how BIR offices will actually apply the law, for example which documents an examiner asks for or how a compromise penalty is computed. Knowing the relevant RMO helps taxpayers prepare, respond to BIR notices and anticipate the BIR's position in an audit.
How it works
BIR Issues the RMO
The Commissioner issues a numbered and dated RMO addressing a procedure, policy or internal guideline, such as audit programs, processing of applications or penalty schedules. RMOs are posted on the BIR website.
Taxpayers Review and Apply
Taxpayers and tax professionals read RMOs that affect them to understand how BIR offices will handle a matter, such as what documents are required or how penalties are computed, and prepare accordingly.
BIR Personnel Enforce Consistently
BIR personnel follow RMOs when processing returns and applications, conducting audits and computing compromise penalties. This supports uniform treatment across revenue districts.
Taxpayer Reliance and Dispute Resolution
The Tax Code bars giving retroactive effect to a revoked or modified BIR rule, ruling or circular when this would prejudice taxpayers, unless the taxpayer misstated facts, the facts turn out different, or the taxpayer acted in bad faith (NIRC Sec. 246).
Examples
Compromise Penalties: RMO 7-2015
RMO 7-2015 contains the schedule of compromise penalties the BIR applies to non-fraud criminal violations of the Tax Code, such as late filing of certain returns. A business owner who receives a compromise penalty computation can compare it with the RMO's schedule. Under RR 6-2024, micro and small taxpayers get at least a 50% reduction for certain violations.
TRAIN Law Implementation: Regulations and Orders
When the TRAIN Law (RA 10963) took effect in 2018, the detailed rules came mainly through Revenue Regulations, such as RR 8-2018 on income tax and RR 11-2018 on withholding, while orders and circulars covered procedures. In 2018 the first taxed bracket was 20% of taxable income over ₱250,000; from 2023 it is 15%.
Estate Tax Rules: Regulation First
The flat 6% estate tax for deaths from January 1, 2018 comes from the TRAIN Law, implemented by RR 12-2018. For an estate whose net estate after deductions is ₱5,000,000, the tax is ₱300,000 (6%). An executor relies on the law and the regulation for the rate; RMOs govern how BIR offices process the return and the electronic Certificate Authorizing Registration.
Withholding Rates: Set by Regulation
Expanded withholding tax rates, such as 5% or 10% on professional fees paid to individuals, are set by Revenue Regulations (RR 11-2018), not by RMOs. An RMO may tell BIR offices how to check compliance with those rates during an audit.
Audit Procedures: Internal Guidelines
RMOs commonly set internal audit programs and processing guidelines, such as the steps examiners follow in reviewing a refund claim. A taxpayer filing a claim can use the applicable RMO to see what documents the examiner is directed to look for.
Common misconceptions
- Myth: RMOs are laws and override the NIRC.
- Fact: RMOs are administrative issuances. They cannot override the NIRC or Revenue Regulations; the power to interpret the Tax Code belongs to the Commissioner, subject to review by the Secretary of Finance (NIRC Sec. 4).
- Myth: RMOs are binding only on BIR personnel, so taxpayers can ignore them.
- Fact: RMOs direct BIR personnel, but they shape how your return, application or audit is handled. Taxpayers read them to prepare documents and anticipate the BIR's position.
- Myth: All BIR issuances are RMOs.
- Fact: The BIR issues several types of guidance: Revenue Regulations (implementing rules promulgated by the Secretary of Finance), RMOs (internal directives), Revenue Memorandum Circulars (announcements and clarifications), and rulings (answers to specific taxpayer requests). Each has a different scope and authority.
- Myth: RMOs are permanent and never change.
- Fact: RMOs are amended, superseded or revoked as laws and procedures change. Taxpayers should use the version in force for the period involved.
Questions people ask
Where can I find and read RMOs?
RMOs are posted on the official BIR website (www.bir.gov.ph) under Issuances, where you can browse by type and year. Tax reference databases also carry them.
If I follow BIR guidance and the BIR later changes its position, can I dispute an assessment?
Possibly. NIRC Sec. 246 bars retroactive application of a revoked or modified BIR rule, ruling or circular when it would prejudice taxpayers, except where the taxpayer misstated or omitted material facts, the facts later gathered are materially different, or the taxpayer acted in bad faith.
Are RMOs the same as Revenue Regulations?
No. Revenue Regulations (RRs) are promulgated by the Secretary of Finance, upon the Commissioner's recommendation, to enforce the Tax Code (NIRC Sec. 244). RMOs are issued by the Commissioner mainly to direct BIR personnel on procedures and policies. RRs carry greater legal weight.
Can an RMO override a Revenue Regulation or the NIRC?
No. RMOs are subordinate to the NIRC and Revenue Regulations. If an RMO conflicts with a higher-order rule, the NIRC or RR controls. A taxpayer who disagrees with an assessment based on the BIR's interpretation can protest it (NIRC Sec. 228).
How often are RMOs issued?
The BIR issues RMOs as needed, with no fixed schedule. Major tax law changes usually bring a series of regulations, orders and circulars over several months.
Do RMOs apply to all taxpayers or only certain groups?
RMOs are addressed to BIR personnel, but their procedures affect the taxpayers concerned. Some cover all taxpayers; others target specific industries, transactions or taxpayer groups. Read the RMO's scope section to see whom it covers.
What should I do if an RMO is unclear or seems to conflict with my situation?
Ask your Revenue District Office for clarification, or request a ruling from the BIR on your specific facts. If an assessment is issued that you disagree with, you may file a protest (NIRC Sec. 228).
In practice
- Tax professionals read the regulations and the RMOs that follow a new law to see both the rules and how BIR offices will apply them.
- Taxpayers cite the applicable regulations, rulings and orders in correspondence with the BIR, such as protest letters and ruling requests.
- RMOs often carry effective dates and transition rules, which matter during the first year of a new law.
- RMO 7-2015's schedule of compromise penalties is a common reference when the BIR computes penalties for non-fraud violations.
- Tax software and accounting systems are updated when new regulations and orders change filing procedures.
