Corporate Income Tax (CIT) Rates and Filing

Overview of Corporate Income Tax

Corporate Income Tax (CIT) is the primary direct tax imposed by the Bureau of Internal Revenue (BIR) on the net taxable income of corporations operating in the Philippines. Under the Tax Reform for Acceleration and Inclusion (TRAIN) Law (RA 10963) and subsequent amendments, the standard CIT rate for regular domestic and foreign corporations is 25% of net taxable income (NIRC §24(A)). However, qualifying Micro, Small, and Medium Enterprises (MSMEs) benefit from a preferential rate of 20%, provided they meet specific criteria under the Corporate Recovery and Tax Incentives for Enterprises (CREATE) Law (RA 11534).

Who Must Pay CIT

CIT applies to all domestic corporations and foreign corporations engaged in trade, business, or profession within the Philippines. Domestic corporations are taxed on their worldwide income, while foreign corporations are taxed only on income derived from Philippine sources (NIRC §24(A)). This includes corporations organized under Philippine law, as well as those incorporated abroad but doing business in the country through a branch or permanent establishment.

Standard CIT Rate: 25%

The regular corporate income tax rate of 25% applies to all domestic and foreign corporations not qualifying for preferential rates. This rate was established under the TRAIN Law (RA 10963, effective 1 January 2018) and remains the baseline for CIT computation. The 25% rate is applied to the corporation's net taxable income, which is gross income minus allowable deductions (NIRC §24(A)).

MSME Preferential Rate: 20%

Under the CREATE Law (RA 11534, effective 1 July 2020), qualifying MSMEs are entitled to a reduced CIT rate of 20%. To qualify, a corporation must meet the following criteria: (1) classified as a micro, small, or medium enterprise based on asset size or revenue thresholds set by the Department of Trade and Industry (DTI); (2) registered with the BIR as an MSME; and (3) not engaged in prohibited activities such as financing, insurance, or real estate development (BIR Memorandum Circular 2020-070). The 20% rate provides significant tax relief for small and medium-sized businesses.

Net Taxable Income Calculation

CIT is computed on net taxable income, calculated as gross income minus allowable deductions. Gross income includes all income derived from business operations, such as sales revenue, service fees, rental income, and other business receipts. Allowable deductions include ordinary and necessary business expenses, cost of goods sold, depreciation, salaries and wages, rent, utilities, and other operating costs (NIRC §34). Non-deductible items include personal expenses, taxes paid to foreign governments (except as a credit), and losses from wagering.

Filing and Payment Requirements

Domestic corporations must file an Annual Income Tax Return (ITR) on or before the 15th day of the fourth month following the close of the taxable year (typically 15 April for calendar-year corporations). Foreign corporations must file within the same deadline. Corporations with gross receipts exceeding ₱3,000,000 in the preceding year are required to file electronically through the BIR's e-filing system (RR 12-2018). Quarterly estimated tax payments (1st to 3rd quarter) are due on the 15th of the month following each quarter, with the final payment due upon filing the annual return (NIRC §57).

Special CIT Regimes

Certain corporations may qualify for alternative CIT regimes. Corporations under the Bayanihan to Recover as One (BARO) Law (RA 11494) may claim a 5% CIT rate for 2020 and 2021 on incremental revenue. Corporations engaged in preferred activities under the Omnibus Investments Code may qualify for income tax holidays or reduced rates. Export-oriented enterprises may benefit from preferential treatment under various investment incentive programs administered by the Board of Investments (BOI) (NIRC §24(D)).

Compliance and Penalties

Failure to file the annual ITR or pay CIT on time results in penalties. Late filing incurs a surcharge of 25% of the unpaid tax, plus interest at 12% per annum from the due date until full payment (NIRC §249). Underpayment of estimated quarterly taxes also triggers interest charges. Corporations must maintain accurate books of accounts and supporting documents for at least three years for BIR audit purposes (NIRC §233).
