G.R. No. L-12174. April 26, 1962.
MARIA B. CASTRO, petitioner, vs. THE COLLECTOR OF INTERNAL REVENUE, respondent.

FACTS

Petitioner Maria B. Castro, a merchant, filed a war profits tax return under Republic Act No. 55 , reporting a minimal increase in net worth from December 8, 1941, to February 26, 1945, resulting in no tax due. The Bureau of Internal Revenue (BIR) subsequently assessed her for a substantial deficiency, leading to a criminal case for tax evasion. During the criminal proceedings, a BIR examiner testified that reinvestigation showed no tax was due, prompting the case’s dismissal. However, the BIR later issued new and significantly higher assessments against Castro. A special committee (the Pedrosa Committee) was formed, which recommended a massive tax liability. This recommendation was approved by the President, and the Collector demanded payment. Castro contested this assessment before the Court of Tax Appeals (CTA), which ruled in favor of the government, finding her liable for a deficiency war profits tax.
The CTA determined Castro’s actual net worth as of February 1945 was far greater than reported, based on an analysis of her expenditures and financial activities in the subsequent years 1945-1947. This method was used to reconstruct her hidden assets and cash on hand at the key date. The CTA also credited against her tax liability the value of properties previously forfeited and sold by the government due to her non-payment. Castro appealed, challenging the assessment’s validity, the computation method, and the credit given for the forfeited properties.

ISSUE

The primary issue is whether the Court of Tax Appeals erred in affirming the deficiency war profits tax assessment against Maria B. Castro based on the reconstructed net worth method and in its treatment of her forfeited properties as a partial tax payment.

RULING

The Supreme Court affirmed the CTA’s decision. The legal logic centers on the propriety of the net worth method for tax assessment when a taxpayer’s records are inadequate or unreliable. The Court held that the BIR correctly used Castro’s post-war expenditures and investments (from 1945 to 1947) as evidence to deduce her true financial position as of the taxable date, February 26, 1945. This reconstruction is a legitimate investigative tool when, as here, the taxpayer’s declared assets are suspect or insufficient to explain her subsequent level of spending and asset acquisition. The Court rejected Castro’s argument that this method improperly averaged income over later years, clarifying that the later expenditures were merely evidence used to fix the net worth at the specific date required by the war profits tax law.
Regarding the forfeited properties, the Court ruled that their sale value was correctly applied as a partial payment against her total tax liability. The Court interpreted the relevant tax code provisions as allowing the government to apply the proceeds from forfeited property to the taxpayer’s debt, and to continue collection efforts for any remaining balance. The Court found no merit in Castro’s claim that the properties were undervalued, placing the burden of proof on her to show a higher value, which she failed to do. Furthermore, her challenge to the validity of the levy and sale itself was barred for not being raised before the CTA. The assessment was upheld as a proper exercise of the state’s power to tax, which cannot be defeated by a taxpayer’s poor record-keeping.
