In Philippine local government law, the transmittal letter serves as the formal vehicle by which the local chief executive—usually the municipal mayor—submits a supplemental budget proposal to the Sangguniang Bayan for legislative approval. This document is not merely administrative correspondence; it is a statutorily required act that triggers the sanggunian’s authority to enact a supplemental appropriation ordinance. Failure to observe the prescribed form, content, and timing may render the entire supplemental budget process defective, exposing the local government unit (LGU) to audit disallowances, delayed implementation of urgent projects, or even administrative sanctions.

Legal Framework Governing Supplemental Budgets and Their Transmittal

The primary statute is Republic Act No. 7160, otherwise known as the Local Government Code of 1991 (LGC). Section 321 explicitly authorizes supplemental budgets when:

(a) there is a new source of revenue or savings realized during the year;
(b) there are unforeseen expenditures arising from natural calamities, public emergencies, or other contingencies; or
(c) there is a realignment of funds within the same expense class pursuant to existing budgetary rules.

Section 322 requires that any supplemental appropriation be enacted through an ordinance passed by the Sangguniang Bayan. The process begins with the executive’s submission of the proposed supplemental appropriation, accompanied by supporting documents, via a formal transmittal letter.

Department of Budget and Management (DBM) Circulars (particularly those implementing the Local Government Code and the annual General Appropriations Act) and the Government Accounting Manual further prescribe that the transmittal must include:

A certified copy of the proposed Supplemental Appropriation Ordinance;
The Supplemental Budget Document (using the prescribed DBM LGU Budget Forms);
A Statement of New Income/Savings or Certification of Unforeseen Events;
A Financial Plan showing sources and uses; and
A certification from the Local Treasurer and the Budget Officer attesting to the availability of funds.

The transmittal letter itself is the cover document that legally binds the package and invokes the sanggunian’s legislative jurisdiction.

Essential Elements of a Valid Transmittal Letter

A transmittal letter for a supplemental budget must strictly adhere to the following mandatory components to be legally sufficient:

Official Letterhead
Use the LGU’s official letterhead containing the seal of the Republic of the Philippines, the name of the municipality, the mayor’s name and title, and complete office address. The letterhead must comply with Republic Act No. 8491 (Flag and Heraldic Code) as to design and color.
Date and Place
Indicate the exact date of issuance (month, day, year) and the place of issuance (e.g., “Municipal Hall, [Municipality], [Province]”). This date is material because it starts the 30-day period within which the Sangguniang Bayan must act (LGC, Sec. 323).
Complete Address of the Recipient
Address the letter to:
“The Honorable Members
Sangguniang Bayan
[Municipality], [Province]”
or to the Vice-Mayor/Presiding Officer by name and title when required by local rules.
Salutation
The standard formal salutation is:
“Honorable Members:”
or, when the Vice-Mayor is specifically addressed:
“Honorable [Vice-Mayor’s Full Name],
Vice-Mayor and Presiding Officer
Sangguniang Bayan
[Municipality]”
Subject Line
Clearly state:
“SUBJECT: TRANSMITTAL OF PROPOSED SUPPLEMENTAL BUDGET NO. __ FOR CY ____ AND THE CORRESPONDING SUPPLEMENTAL APPROPRIATION ORDINANCE”
Body – Opening Paragraph
Identify the sender’s authority:
“Pursuant to Sections 321 and 322 of Republic Act No. 7160, otherwise known as the Local Government Code of 1991, and in accordance with the rules and regulations promulgated by the Department of Budget and Management, I have the honor to transmit herewith the Proposed Supplemental Budget No. __ for Calendar Year ____ in the total amount of Pesos: ________________ (PhP_____.00).”
Justification Paragraph
Succinctly state the legal basis and factual grounds (new revenue, savings, calamity, etc.). Reference the specific source document (e.g., “as certified by the Municipal Treasurer in his Certification dated ____” or “arising from the savings realized from the completion of projects under the 20% Development Fund”).
Reference to Enclosed Documents
Enumerate all attached documents using numbered paragraphs for clarity and audit trail. Example:
“The following documents are hereto attached:
1. Proposed Supplemental Appropriation Ordinance No. __, Series of ____;
2. Supplemental Budget Document (Forms 1, 2, and 3);
3. Certification of Availability of Funds;
4. Statement of Income and Expenditures; and
5. Detailed Financial Plan.”
Request for Legislative Action
Explicitly request enactment:
“In view of the foregoing, I respectfully request the Honorable Sangguniang Bayan to deliberate and enact the corresponding Supplemental Appropriation Ordinance at the earliest possible time.”
Closing and Signature Block
Standard valediction:
“Respectfully submitted.”
Followed by:
“[Mayor’s Full Name]
Municipal Mayor”
The signature must be original (wet ink) or, when allowed under local electronic rules, digitally signed in accordance with Republic Act No. 8792 (Electronic Commerce Act).

Step-by-Step Guide to Writing the Letter

Step 1: Gather all required supporting documents and certifications before drafting.
Step 2: Verify fund availability with the Municipal Treasurer and Budget Officer; obtain their signed certifications.
Step 3: Draft the letter using the exact legal citations (RA 7160, Secs. 321-323) to prevent any claim of procedural defect.
Step 4: Use formal, concise language; avoid colloquialisms or unnecessary adjectives.
Step 5: Number all enclosures and ensure the total amount stated in the letter exactly matches the ordinance.
Step 6: Have the letter reviewed by the Municipal Legal Officer for legal sufficiency.
Step 7: Obtain the mayor’s wet signature and affix the official seal.
Step 8: Deliver the complete package personally to the Sangguniang Bayan Secretary or through the Vice-Mayor’s office, obtaining a stamped receipt with date and time.

Common Pitfalls and How to Avoid Them

Omitting the exact legal basis (Secs. 321-322) – renders the transmittal legally infirm.
Mismatch between the amount in the letter and the ordinance – causes automatic return or delay.
Failure to attach the required certifications – the sanggunian may refuse to act.
Late submission after the fiscal year – supplemental budgets are generally not allowed beyond December 31 except in specific calamity cases.
Addressing the letter to the wrong official (e.g., directly to a councilor instead of the body) – invalidates the submission.
Use of non-official stationery or missing seal – treated as a mere private communication.

Pursuant to Sections 321 and 322 of Republic Act No. 7160, otherwise known as the Local Government Code of 1991, I have the honor to transmit herewith the Proposed Supplemental Budget No. __ for Calendar Year ____ in the total amount of Pesos: ________________ (PhP_____.00).

The proposed supplemental appropriations are sourced from [state source: e.g., “additional internal revenue allotment received in the third quarter” or “savings from completed infrastructure projects”] as certified by the Municipal Treasurer and the Municipal Budget Officer.

The following documents are attached for your immediate consideration:

Proposed Supplemental Appropriation Ordinance No. __, Series of ____;
Supplemental Budget Document (DBM Forms 1, 2, and 3);
Certification of Availability of Funds dated ______;
Statement of New Income and Savings; and

Jurisprudential and Audit Considerations

The Commission on Audit (COA) has consistently ruled in numerous disallowance cases that a supplemental budget is null and void ab initio if the transmittal letter fails to comply with the documentary requirements of DBM Circular No. 2012-2 (as amended) or if the sanggunian did not receive the complete package. Courts have upheld this strict compliance rule in cases involving emergency purchases and calamity funds. Consequently, the transmittal letter must be treated with the same solemnity as a legislative bill.

By mastering the foregoing elements, structure, and legal citations, any municipal legal officer, budget officer, or mayor can produce a transmittal letter that is not only legally impeccable but also ensures swift legislative approval and seamless implementation of vital supplemental programs for the benefit of the local constituency.
