Background and Payment Refusal

Quimpo’s property, assessed at P20,000, carried a P400 annual tax under RA 5447’s four-installment system. He timely paid the first three installments (P300). On August 27, 1970 he tendered P124 (P100 installment + P24 penalty) for the final installment. Mendoza refused, insisting on P196 (P100 + P96 penalty) based on RA 521’s penalty provision as interpreted in Padilla. Quimpo then instituted a mandamus suit and consigned P124.

Lower Court Ruling

The Court of First Instance held that, despite installment dates, the annual tax was due in full on June 1, making any late payment delinquent on the entire P400. Relying on Padilla, it computed a P96 penalty (2% per month on P400 from April 1969 to July 1970). It dismissed Quimpo’s suit for lack of payment under protest per RA 521.

Effect of RA 5447 on Due Dates

RA 521 fixed one due date (June 1) with a two-installment option. RA 5447, effective January 1, 1969, amended all city charters to require payment of both basic and additional tax in four equal installments, each with its own due date. As the later statute, RA 5447 superseded RA 521’s singular due-date rule for 1969, making December 31 the final due date and postponing delinquency on that installment until January 1 of the following year.

Penalty Computation Basis

RA 5447 did not amend RA 521’s penalty provision (2% per month on the “original tax due”). By analogy to PD 464’s quarterly penalty rule and construing tax statutes in favor of the taxpayer, the penalty must be calculated on the amount of the delinquent installment (P100), not on the full annual tax.

Revised Liability Calculation

Delinquency on the fourth installment ran eight full months (January–August 1970).
– Installment due: P100.00
– Penalty: 8 months × 2% × P100 = P16.00
– Total liability: P116.00
