Timor-Leste Corporate Tax Guide: CIT 10%, Petroleum Regime 2026
Timor-Leste's Corporate Income Tax (CIT) regime features a standard rate of 10%, one of the lowest in Asia. The oil and gas sector operates under a separate Petroleum Fund regime. There are no reduced rates for small businesses — the 10% rate applies uniformly. Here is how Timorese corporate tax works in 2026.
Corporate Income Tax in Timor-Leste is governed by the Income Tax Act (Law No. 8/2008) and administered by the Autoridade Nacional do Imposto (ANI). The standard CIT rate of 10% applies to all legal entities. Timor-Leste offers one of the most competitive corporate tax regimes in Asia, significantly lower than Indonesia (22%), Philippines (25%), and Australia (25-30%). The tax year is the calendar year. Companies must file annual CIT returns by March 31 of the following year. Filing and compliance guide →
Real-world example: A Dili-based consulting company with annual turnover of USD 500,000 and taxable profit of USD 150,000 pays CIT at 10% = USD 15,000. An importer with USD 2 million turnover and USD 200,000 profit pays CIT at 10% = USD 20,000. Compare this to Indonesia where the same profits would incur 22% CIT, or Australia at 25-30%. Oil and gas companies operate under separate Petroleum Fund taxation with different rates. Cross-border taxation →
Corporate Tax Rate Structure
- 10% (standard rate): All companies and legal entities — no reduced rates for small businesses
- Branch tax: Foreign company branches are taxed at 10% on Timor-Leste-source income
- Petroleum activities: Oil and gas companies are taxed under the Petroleum Fund regime (separate tax law)
The 10% rate applies uniformly across all sectors except petroleum. There are no surcharges, regional taxes, or municipal business taxes. The system is notably simple compared to regional peers.
Taxable Income and Deductions
Corporate taxable income is calculated as accounting profit adjusted for tax purposes. Key rules include:
- Depreciation: Standard rates apply — buildings 4%, machinery 12.5%, vehicles 20%, computers 25%
- Interest deductibility: Thin capitalization rules limit interest deductions
- Loss carryforward: Tax losses can be carried forward for 5 years
- Dividend income: Dividends received from Timorese resident companies may be exempt
- Capital gains: Treated as ordinary income and taxed at standard CIT rate of 10%
Transfer pricing rules apply for transactions with related parties. Timor-Leste follows OECD guidelines for transfer pricing documentation. Cross-border taxation →

Tax Incentives and Exemptions
Timor-Leste offers incentives to attract investment, primarily through the Private Investment Law:
- Strategic investments: Tax holidays and customs duty exemptions for qualifying large investments in priority sectors
- Economic zones: Incentives for companies operating in special economic zones
- Employment incentives: Benefits for hiring Timorese workers and training
- Infrastructure development: Enhanced deductions for infrastructure investments
Incentives typically require prior approval through the TradeInvest Timor-Leste agency. Minimum investment thresholds and job creation commitments apply.
Who needs to register for CIT in Timor-Leste?
All legal entities (companies, partnerships, branches of foreign entities) must register for CIT with the ANI. Registration is required before starting business operations. Non-resident companies with a permanent establishment in Timor-Leste are also subject to CIT on Timor-Leste-source income.
What is the filing deadline for corporate tax?
Annual CIT returns must be filed by March 31 of the following year. Tax is generally paid at the time of filing. Late filing penalties apply. There is no quarterly installment payment system for CIT.
Are there any regional or municipal taxes?
No. Timor-Leste has a unitary tax system with no regional or municipal corporate taxes. The 10% CIT is the only corporate-level tax. There is no trade tax, business tax, or local surcharge on corporate profits.
