Kiribati Corporate Tax Guide: CIT 25% Standard Rate 2026
Kiribati's Corporate Income Tax (CIT) regime features a standard rate of 25% applicable to all resident companies. There are no reduced rates for small businesses or micro-enterprises. The tax is administered by the Ministry of Finance and Economic Development — Tax Office. Here is how corporate tax works in Kiribati in 2026.
Corporate Income Tax in Kiribati is governed by the Income Tax Act and administered by the Tax Office within the Ministry of Finance and Economic Development. The standard CIT rate of 25% applies to all legal entities. There are no reduced rates for small businesses, unlike many neighbouring Pacific nations. The tax year follows the calendar year. Companies must file annual CIT returns by March 31 of the following year. Filing and compliance guide →
Real-world example: A Tarawa-based trading company with annual turnover of AUD 500,000 and taxable profit of AUD 80,000 pays CIT at 25% = AUD 20,000. A small retail shop with AUD 60,000 profit also pays the standard 25% rate = AUD 15,000. Compare this to Fiji where the same profits would incur CIT at 20% (standard) or 18% for small companies, or Australia at 25% (small business) to 30% (large business). Kiribati's flat rate is simple but relatively high compared to some regional competitors. IT sector guide →
Corporate Tax Rate Structure
- 25% (standard rate): All resident companies pay CIT at 25% on taxable profits
- No reduced rates: Kiribati does not offer reduced CIT rates for small businesses, micro-enterprises, or startups
- Branches: Foreign company branches operating in Kiribati are taxed at the same 25% rate on Kiribati-source income
Unlike many Pacific island nations that offer tiered rates (e.g., Fiji with 18% for small companies, Papua New Guinea with tiered rates), Kiribati maintains a single standard rate. This simplifies administration but means small businesses do not receive targeted tax relief.
Taxable Income and Deductions
Corporate taxable income is calculated as accounting profit adjusted for tax purposes. Key rules include:
- Depreciation: Standard rates apply for fixed assets under tax depreciation schedules
- Interest deductibility: Interest on business loans is generally deductible
- Loss carryforward: Tax losses can be carried forward for a limited period
- Capital gains: Kiribati has no capital gains tax — capital gains are not subject to CIT
- Business license tax: In addition to CIT, businesses pay an annual business license tax of AUD 100-500 per year
Transfer pricing rules are limited. Kiribati has a small economy with limited cross-border related-party transactions compared to larger economies. Cross-border taxation →
