G.R. No. 36994 - Boada vs. Posadas

Emilio Boada, Pedro Boada, and Jose Boada were partners in the unregistered partnership known as "Los Catalanes de Pedro Boada."
The partnership was engaged in the sale of merchandise for approximately fifteen years, during which it duly paid the internal revenue taxes as a de facto registered partnership.
Emilio Boada, a partner in the aforementioned partnership, later became a stockholder in the newly formed corporation "Boada, Castro & Penafiel" following a merger.

On February 1, 1927, the partnership was dissolved for the purpose of merging into the new corporation.
Emilio Boada’s interest in the partnership consisted of an amount of ₱57,112.51 and the inventoried value of certain merchandise, which was turned over to the new corporation.
The transfer was facilitated under an arrangement where the payment for the merchandise was guaranteed by a reserve fund. This fund was to be established by an annual amortization of not less than 15% of the profits, accruing interest at 8% per annum, with subsequent cancellation as payments were made.

Although the partnership "Los Catalanes de Pedro Boada" had been paying the merchant tax as a de facto registered partnership, Emilio Boada had never been required to pay any such tax in his individual capacity.
The Bureau of Internal Revenue administered taxes on the partnership as if it were a registered entity, despite its unregistered status.
Emilio Boada argued that having retired by selling his interest, the single commercial act of transfer should not classify him as a merchant liable for the 1% internal revenue tax.

Administrative rulings provided by the Collector of Internal Revenue were cited:

Ruling No. 6 (1922) – A partner transferring his interest to another partner was not subject to the merchant tax.
Ruling of June 23, 1921 – A partner selling his interest to another partnership constituted by the same partners was not liable for the tax.
Ruling of February 3, 1924 – Capital transferred to a corporation merely to benefit from the Corporation Law benefits did not incur the 1% tax.

The case of Whitaker vs. Rafferty established that engaging in a single commercial act (sale, barter, or exchange of personal property) does not suffice for one to be considered “engaged” in commerce for tax purposes.
The Bureau of Internal Revenue’s position questioned whether an unregistered partnership, lacking independent juridical personality, could be considered as such for taxation, but had previously treated it as a de facto corporation.

Whether Emilio Boada could be deemed a merchant under the law by virtue of his past association with the unregistered partnership "Los Catalanes de Pedro Boada."
If the commercial acts of the unregistered partnership could be imputed to Emilio Boada, thereby making him liable to pay the 1% internal revenue tax.

Whether the transfer of Emilio Boada’s interest from the unregistered partnership to the new corporation "Boada, Castro & Penafiel" constitutes a commercial act that subjects him to the merchant tax.
The implications of treating an unregistered partnership as having a de facto corporate personality for taxation purposes.

Whether prior administrative rulings and the decision in Whitaker vs. Rafferty provide sufficient basis to exempt Emilio Boada from the tax.
The proper interpretation of “engaged in commerce” and whether a single isolated act is enough to trigger merchant status.
