Minimum Corporate Income Tax (MCIT)

MCIT is a 2% tax on gross income that corporations pay when it is higher than their regular corporate income tax (25%, or 20% for qualifying small domestic corporations). It applies from the fourth taxable year after the year the corporation began operations.

MCIT is calculated by multiplying gross income by 2%. Gross income here means gross sales less returns, discounts and allowances and cost of goods sold (or, for service companies, gross receipts less cost of services). For example, if a corporation has ₱10,000,000 gross income, MCIT = ₱10,000,000 × 2% = ₱200,000. This is compared with the regular tax, and the higher amount is paid (NIRC §27(E)).

Regular corporate tax is 25% (or 20% for qualifying small domestic corporations) of net taxable income after all deductions, while MCIT is 2% of gross income, which is sales less cost of goods sold but before operating expenses. Corporations pay whichever amount is higher.

MCIT applies to domestic and resident foreign corporations beginning on the fourth taxable year immediately following the year in which they commenced business operations. In the year operations start and the next three years, it does not apply (NIRC §27(E)(1), §28(A)(2)).

Yes, any excess MCIT paid over regular income tax can be carried forward and credited against regular income tax for the succeeding three taxable years, providing relief for corporations that paid higher MCIT.

MCIT establishes a tax floor that cannot be eliminated through deductions, making it crucial for cash flow planning and ensuring corporations budget for minimum tax obligations regardless of profitability after expenses.

Corporations with net operating losses still owe MCIT on their gross income once they are past their first years of operation. Even with zero regular tax, they must pay 2% MCIT, which can be carried forward for credit against regular tax. The Secretary of Finance may suspend MCIT for a corporation that suffers losses from a prolonged labor dispute, force majeure or legitimate business reverses (NIRC §27(E)(3)).

MCIT is computed on the corporation's quarterly income tax return (BIR Form 1702Q) and on its annual income tax return, such as BIR Form 1702-RT for corporations subject to the regular rate. The higher of MCIT or regular tax is the tax due. BIR Form 1700 is for individuals earning purely compensation income and is not used by corporations.

Common errors include applying MCIT before the fourth taxable year after operations started, deducting operating expenses when computing gross income for MCIT, forgetting to credit excess MCIT from the three preceding years, and failing to keep documentation for the gross income computation.

Underpaying the tax due results in a 25% surcharge under Section 248 and interest at 12% a year under Section 249. Micro and small taxpayers pay a 10% surcharge and 6% interest instead. Incorrect MCIT computation can also lead to deficiency assessments with these additions.
