Premium Tax vs Cost of Service: Defining Minimum Corporate Income Tax

The Minimum Corporate Income Tax (MCIT) is a tax imposed on domestic corporations at 2% of gross income, designed to ensure that corporations pay at least a minimum amount of tax even if they report losses or low profits. For insurance companies, a key question has always been: which expenses can be deducted from gross receipts to arrive at the gross income subject to MCIT?

In Manila Bankers' Life Insurance Corporation v. Commissioner of Internal Revenue (G.R. Nos. 199729-30 and 199732-33, February 27, 2019), the Supreme Court settled this question. The Court ruled that premium taxes are not deductible "costs of services" in computing MCIT, while also clarifying when documentary stamp taxes (DST) apply to increases in insurance coverage.

The Case Background

Manila Bankers' Life Insurance Corporation (MBLIC) received deficiency tax assessments from the Bureau of Internal Revenue (BIR) for taxable year 2001, including deficiency MCIT and DST. The BIR disallowed MBLIC's deductions of premium taxes and DSTs from gross receipts, citing Revenue Memorandum Circular No. 4-2003 (RMC 4-2003), which enumerated the allowable "costs of services" for insurance companies.

MBLIC protested, arguing that RMC 4-2003, issued in December 2002, could not be applied retroactively to assess its 2001 taxes. The company also contested the DST assessment on increases in the assured amount of existing insurance policies where no new policy was issued.

The Legal Framework: The NIRC Provision on MCIT

The National Internal Revenue Code (NIRC) imposes MCIT on domestic corporations and defines "gross income" for this purpose as gross receipts less sales returns, allowances, discounts, and cost of services. The provision defines "cost of services" as all direct costs and expenses necessarily incurred to provide the services required by customers, including salaries and employee benefits of personnel directly rendering the service, and cost of facilities directly utilized.

The exact text of this provision is not available in the ASG law library. However, the Supreme Court's decision in this case quotes the provision and explains that the phrase "including" makes the enumeration non-exhaustive, but the key requirement is that the expense must be a direct cost.

RMC 4-2003 Cannot Be Applied Retroactively

The Court ruled that RMC 4-2003 could not be used to assess MBLIC's 2001 deficiency taxes. Under the NIRC's non-retroactivity rule, rulings and circulars cannot be given retroactive application if prejudicial to taxpayers. Since RMC 4-2003 imposed a restrictive enumeration of allowable costs, applying it to 2001 would violate this principle.

The Court cited its ruling in Pilipinas Total Gas, Inc. v. CIR, which held that a revenue memorandum circular imposing new obligations on taxpayers cannot be applied retroactively.

Premium Taxes Are Not Deductible Costs of Services

The Court reversed the Court of Tax Appeals on this point. While premium taxes are paid by insurance companies, they are not direct costs. A cost is "direct" when it is readily attributable to the production of goods or rendition of services. Premium taxes are incurred after the sale of service has already transpired—they are a consequence of the transaction, not a cost of producing the service itself.

The Court emphasized that allowing premium taxes as deductions would erase the distinction between "gross income" for MCIT purposes and "gross income" for basic corporate income tax purposes.

DSTs Are Also Not Deductible Costs of Services

The Court affirmed that DSTs are not deductible costs of services for MCIT purposes. Under the NIRC's general DST provision, the tax is imposed on the person making, signing, issuing, accepting, or transferring the document. Since MBLIC charged the DST to its clients as part of their premiums, it could not claim that it necessarily incurred the expense as a direct cost of providing insurance services.

DST Applies to Increases in Insurance Coverage

The Court ruled that an increase in the assured amount of an insurance policy is subject to DST even if no new policy is issued. Under the NIRC provision on assignments and renewals of certain instruments, a policy that is renewed or continued by altering or otherwise attracts DST at the same rate as the original instrument. An automatic increase clause that alters the coverage creates new and additional rights for policyholders, triggering the tax.

The Court applied its earlier ruling in Commissioner of Internal Revenue v. Lincoln Philippine Life Insurance Company, Inc., which held that an automatic increase clause in a life insurance policy subjects the increased amount to DST even without a new policy being issued.

Other Rulings

The Court also held that MBLIC's defense of prescription was not sufficiently established—while the defense may be raised even for the first time on appeal, the company failed to prove that the assessed DSTs pertained to periods already barred by the three-year prescriptive period. Finally, the Court affirmed that compromise penalties cannot be imposed without a mutual agreement between the taxpayer and the BIR.

Practical Takeaways

• Premium taxes are not deductible "costs of services" for MCIT computation. Insurance companies should compute their MCIT without deducting premium taxes from gross receipts.
• RMC 4-2003 applies prospectively only. Taxpayers cannot be assessed based on revenue issuances that were not yet in effect during the taxable year in question.
• DST on policy increases is due even without a new policy. Any alteration that increases the assured amount triggers additional DST under the NIRC.
• The defense of prescription must be supported by evidence. Taxpayers must prove which specific assessments are barred by the prescriptive period.
• Compromise penalties require mutual agreement. The BIR cannot unilaterally impose compromise penalties on a protesting taxpayer.
