G.R. No. L-25926 - Commissioner of Internal Revenue vs. Constantino

The Commissioner of Internal Revenue (petitioner) assessed a commercial broker’s percentage tax of 6% on respondent Cirilo D. Constantino’s gross compensation for 1956.
The assessment was based on respondent’s activities as a dealer or distributor of International Harvester, Macleod, Inc. (IHM) products under an exclusive “Dealer Sales and Service Agreement.”
Constantino protested the assessment on the ground that he was not a commercial broker, contending he operated as an independent merchant rather than as an agent.

Respondent maintained a business establishment “C.C. Motor Service” in San Pablo City where he stored, displayed, and sold trucks, machinery, equipment, spare parts, and accessories provided by IHM.
The relationship with IHM was governed by several documents:

“Dealer Sales and Service Agreement” designating Constantino as an exclusive dealer within a prescribed territory.
“Schedule of Discounts and Terms” that granted him a trade discount of 16% for trucks, tractors, and heavy equipment, and a cash discount of 5% under certain conditions.
“Retail Financing Agreement” for regulating the credit purchase terms.
“Dealer Order for Goods” which he used to file his purchase orders; this document contained a clause stating that title to the goods remained with IHM until full payment was rendered.

Additional documents relating to credit sales involved requirements such as chattel mortgages and indentures of assignment to secure transactions.
Despite the issuance of his own sales invoices for resale transactions, the underlying contractual provisions revealed that respondent never acquired actual title or ownership of the goods.

The Commissioner argued that, for tax purposes, Constantino was not an independent merchant but rather functioning as a commercial broker or agent of IHM.
Respondent, however, maintained that his relationship with IHM was that of vendor and vendee, meaning he was purchasing goods for resale rather than merely acting as an agent.
Examination of the documents and internal practices revealed that even though the agreements were labeled with terms such as “purchase” or “sale,” the legal effect was that IHM retained control over the goods and the proceeds from their eventual resale.

The Court of Tax Appeals (CTA) had originally ruled in favor of respondent Constantino, holding that he was not a commercial broker under Section 194(t) of the National Internal Revenue Code.
On appeal, the Commissioner contested the CTA’s decision leading to the present review by the Supreme Court.

The tax was computed based on the total discount for 1956 amounting to ₱38,390.40, resulting in a broker’s percentage tax of ₱2,303.40.
A 25% surcharge (₱575.85) and a compromise penalty of ₱100.00 were added, culminating in a total assessed amount of ₱2,979.25.
The assessment did not include the 30% discount applicable on service parts, which was treated separately due to different contractual arrangements.

Whether the contractual relationship between Constantino and IHM constitutes that of principal and agent (i.e., making Constantino a commercial broker) or that of vendor and vendee (i.e., an independent merchant engaging in resale).
Whether the control, terms, and conditions embedded in the various agreements—particularly the “Dealer Order for Goods” and “Dealer Sales and Service Agreement”—effectively deprive Constantino of ownership and render him merely an agent for IHM.
The implications of the true nature of the relationship on the applicability of the commercial broker’s percentage tax under Section 194(t) of the National Internal Revenue Code.
