A Guide to Corporate Income Tax in 2025

Corporate Income Tax in Indonesia is a key aspect of running a business. Understanding tax rates, incentives, and deductions helps optimise tax obligations. This guide breaks down Indonesia’s corporate income tax structure, incentives for new companies, allowable deductions, and corporate income tax deadlines. 

Fiscal Year in Indonesia

The fiscal year (or tax year) in Indonesia follows the calendar year, from the 1^st of January to the 31^st of December. 

Corporate Income Tax Rates in Indonesia

Indonesia’s standard corporate income tax rate is 22%. However, businesses may qualify for reduced rates. Small enterprises with an annual revenue below IDR 50 billion receive a 50% reduction on taxable income up to IDR 4.8 billion. Companies earning between IDR 4.8 billion and IDR 50 billion pay tax progressively, with effective rates between 11% and 22%.  

Tax Incentives for Newly Incorporated Companies

To boost business growth, Indonesia offers tax incentives for new companies. For the first three (3) fiscal years, companies with turnover below IDR 4.8 billion can benefit from a 0.5% tax on gross revenue rather than net profits. However, this tax incentive has limitations: 

• Business expenses cannot be deducted. 

• Losses cannot be carried forward to future years. 

Strategic Considerations

Businesses anticipating substantial early-stage losses may choose to forego this tax incentive from the outset. This allows losses to be carried forward for up to five (5) years, offsetting future taxable income and reducing tax liability. 

Deductions and Allowable Expenses

Businesses can lower taxable income by claiming various deductions. Cost of Goods Sold (COGS), general and administrative expenses, marketing, research and development, and other operating costs and deductible. Depreciation and amortization allow businesses to spread asset costs over their useful life. Bad debts can be deducted if properly documented, while interest expenses are allowed within these capitalization rules. Corporate Social Responsibility (CSR) expenses are deductible when linked to business activities.  

Corporate Income Tax Deadlines

Taxpayers must pay Monthly CIT Instalments (Article 25 Income Tax) based on the previous year’s tax return. They must make the payment by the 15th of the following month and file the tax return by the 20th.

The Annual Corporate Income Tax Return and Payment are due by the 30^th of April of the following year. Late payments or filings may result in penalties and interest charges.  

If a company overpays tax, it can apply for a refund or credit against future tax liabilities. However, such refund will trigger a tax audit.
