The framework for Corporate Income Tax (Pajak Penghasilan Badan, or PPh Badan) in Indonesia is primarily governed by Law No. 7 of 1983 on Income Tax, which has undergone multiple significant amendments, most recently through Law No. 11 of 2020 on Job Creation (the Omnibus Law) and Law No. 7 of 2021 on the Harmonization of Tax Regulations (UU HPP). These statutes, supplemented by Government Regulation (PP) No. 55 of 2022, establish the legal basis for taxing the income of legal entities established or domiciled in Indonesia.

Tax Subjects and Residency

Under Article 2, Paragraph (1) of the Income Tax Law, a corporate tax subject (Subjek Pajak Badan) is defined as any organized group of persons and/or capital that constitutes a unit, whether conducting business or not. This includes limited liability companies (PT), limited partnerships (CV), state-owned enterprises (BUMN), regional government-owned enterprises (BUMD), cooperatives, foundations, and permanent establishments (BUT).

A corporation is considered a domestic tax subject if it is established or domiciled in Indonesia. Conversely, foreign entities are taxed only on income derived from Indonesian sources, often through a permanent establishment (Bentuk Usaha Tetap), which is treated as a resident taxpayer for most compliance purposes. Article 2, Paragraph (5) of the Income Tax Law defines a BUT as:

“bentuk usaha yang dipergunakan oleh orang pribadi yang tidak bertempat tinggal di Indonesia… atau badan yang tidak didirikan dan tidak bertempat kedudukan di Indonesia untuk menjalankan usaha atau melakukan kegiatan di Indonesia.” (a form of business used by individuals not residing in Indonesia… or entities not established and not domiciled in Indonesia to conduct business or carry out activities in Indonesia.)

Taxable Objects and Income Determination

The object of corporate tax is “income,” defined broadly under Article 4, Paragraph (1) of the Income Tax Law as any increase in economic prosperity received or accrued by a taxpayer, originating from both within and outside Indonesia, which can be used for consumption or to increase the taxpayer’s wealth. For corporations, this includes business profits, gains from the sale or transfer of property, interest, dividends, royalties, and rents.

The determination of taxable income (Penghasilan Kena Pajak) follows the accrual principle, unless specific regulations allow for the cash basis. Taxable income is calculated by deducting allowable expenses from gross income. Under Article 6, Paragraph (1), deductible expenses include costs directly or indirectly related to earning, collecting, and maintaining income (3M - mendapatkan, menagih, dan memelihara penghasilan), such as:

  1. Costs of materials and wages.
  2. Interest, rent, and royalties.
  3. Travel expenses.
  4. Bad debt losses (subject to strict requirements).
  5. Insurance premiums.
  6. Promotion and administrative costs.
  7. Depreciation and amortization.

Non-deductible expenses, as stipulated in Article 9, Paragraph (1), include profit distributions (dividends), reserves (except for specific industries like banking and mining), personal expenses of shareholders, and income tax payments.

Corporate Tax Rates

The standard corporate income tax rate has undergone historical shifts to maintain regional competitiveness. While Law No. 36 of 2008 originally set a path toward lower rates, Law No. 7 of 2021 (UU HPP) Article 17, Paragraph (1) letter b, fixed the current standard rate:

  1. A flat rate of 22% applies to most domestic corporate taxpayers and permanent establishments starting from the 2022 fiscal year.
  2. Publicly listed companies (Perusahaan Terbuka) that meet specific criteria—including a minimum of 40% of total paid-up shares traded on the Indonesia Stock Exchange and held by at least 300 parties—are eligible for a 3% reduction, resulting in an effective rate of 19%, as per Article 17, Paragraph (2b).

Small and Medium Enterprise (SME) Relief

To support smaller entities, Article 31E of the Income Tax Law provides a tax reduction for domestic corporate taxpayers with a gross turnover of up to IDR 50,000,000,000 (fifty billion Rupiah). These entities receive a 50% reduction in the standard tax rate applied to the portion of taxable income corresponding to a gross turnover of IDR 4,800,000,000.

Furthermore, under PP No. 55 of 2022 (which replaced PP No. 23 of 2018), small-scale corporate taxpayers (specifically PT, CV, and Cooperatives) with an annual gross turnover not exceeding IDR 4.8 billion may opt for a final income tax rate of 0.5% on gross turnover for a limited duration:

  1. 3 years for Limited Liability Companies (PT).
  2. 4 years for Cooperatives, Limited Partnerships (CV), and Firms (Firma).

Depreciation and Amortization

The framework for recovering capital expenditures is governed by Article 11 (depreciation of tangible assets) and Article 11A (amortization of intangible assets). Assets are categorized into four groups based on their useful life, with depreciation calculated using either the straight-line method (garis lurus) or the declining-balance method (saldo menurun).

According to Minister of Finance Regulation (PMK) No. 72 of 2023, the categories are:

  1. Group 1: 4 years (25% straight-line / 50% declining).
  2. Group 2: 8 years (12.5% straight-line / 25% declining).
  3. Group 3: 16 years (6.25% straight-line / 12.5% declining).
  4. Group 4: 20 years (5% straight-line / 10% declining).
  5. Buildings: Permanent (20 years, 5% straight-line) and Non-permanent (10 years, 10% straight-line).

Fiscal Loss Carry-Forward

If a corporation’s deductible expenses exceed its gross income, the resulting fiscal loss can be carried forward to offset taxable profits in subsequent years. Article 6, Paragraph (2) of the Income Tax Law limits this carry-forward period to 5 consecutive years. Extensions of this period (up to 10 years) are generally restricted to specific investment incentives or sectors, which fall outside the scope of this general framework.

Compliance and Filing

Corporate taxpayers are required to calculate their own tax liability (self-assessment system). The Annual Corporate Income Tax Return (SPT Tahunan PPh Badan) must be filed no later than four months after the end of the fiscal year (typically April 30th for calendar-year taxpayers). Monthly installments of tax (PPh Article 25) are required to be paid based on the previous year’s tax liability to ensure steady state revenue, as regulated under Article 25 of the Income Tax Law.
