G.R. No. L-16626 October 29, 1966
COMMISSIONER OF INTERNAL REVENUE, petitioner, vs. CARLOS PALANCA, JR., respondent.

FACTS

The late Don Carlos Palanca, Sr. donated 12,500 shares of La Tondena, Inc. stock to his son, respondent Carlos Palanca, Jr., in July 1950. For failure to file a gift tax return on time, the respondent was assessed and paid gift tax, surcharge, and interest totaling P170,002.74 on June 22, 1955. On March 1, 1956, he filed his 1955 income tax return, reporting a taxable income of P65,982.12 and paying a total income tax of P21,052.01. Subsequently, the Bureau of Internal Revenue (BIR) reconsidered the transaction and deemed the transfer to be “in contemplation of death” under Section 88(b) of the Tax Code. Consequently, it assessed the respondent P191,591.62 for estate and inheritance taxes on the same shares. The previously paid gift tax (P170,002.74) was credited against this new liability, and the respondent paid an additional P60,581.80 as delinquency interest on the estate tax. On August 12, 1958, the respondent filed an amended 1955 income tax return, claiming an additional deduction of P60,581.80 for the interest paid on the estate and inheritance taxes. This resulted in a recomputed net taxable income of P5,400.32 and a tax due of only P428.00. He thus claimed a refund of P20,624.01, representing the difference between the amount originally paid (P21,052.01) and the recomputed tax due. The BIR denied this claim. The respondent filed a petition for review with the Court of Tax Appeals (CTA) on August 13, 1958, even before the BIR’s formal denial on July 24, 1959. The CTA ordered the refund. The Commissioner of Internal Revenue appealed, arguing that (1) interest paid on a tax delinquency is not deductible as “interest on indebtedness” under Section 30(b)(1) of the Tax Code, and (2) the claim for refund had prescribed.

ISSUE

1. Whether the interest paid by the respondent on his delinquent estate and inheritance tax is deductible from gross income as “interest paid… on indebtedness” under Section 30(b)(1) of the National Internal Revenue Code.
2. Whether the respondent’s claim for refund of the alleged overpaid income tax had prescribed.

RULING

1. Yes. The Supreme Court affirmed the CTA’s ruling that the interest paid on the delinquent estate tax is deductible. While recognizing a general distinction between a “tax” and a “debt,” the Court held that for the purpose of Section 30(b)(1), a tax may be considered an indebtedness because it constitutes an unconditional and legally enforceable obligation for the payment of money. The Court adhered to its precedent in Commissioner of Internal Revenue v. Prieto (G.R. No. L-13912, September 30, 1960), which ruled that interest paid for the late payment of a donor’s tax is deductible. The nature of the underlying tax (donor’s tax in Prieto, estate tax in this case) does not alter the application of the doctrine, as the deductibility is based on congressional intent underlying the statute, not on the specific type of tax.
2. No, the claim did not prescribe. The Court provided two grounds. First, regarding the 30-day period to appeal to the CTA under Republic Act No. 1125, the claim subject of the suit (filed August 13, 1958) was different from an earlier claim for a refund of interest on gift tax. The BIR’s denial of the specific claim for refund of estate tax interest was issued only on July 24, 1959, after the petition was filed. Second, regarding the two-year prescriptive period for filing a suit under Section 306 of the Tax Code, the Court ruled that since the 1955 income tax was paid in installments, the two-year period should be computed from the date of the last payment, which was August 14, 1956. The petition was filed on August 13, 1958, which was within the two-year period. The decision of the Court of Tax Appeals was affirmed.
