Tax Framework

Papua New Guinea’s fiscal environment for investment is defined by the corporate tax regime, resource-specific taxation, incentive structures, and the country’s network of double taxation agreements. InvestPNG provides structured analysis of the tax framework to support investment structuring and financial modelling.

Corporate Income Tax

Papua New Guinea applies a corporate income tax to resident and non-resident companies operating in the country. Resident companies are taxed on worldwide income, while non-resident companies are taxed on PNG-sourced income. The tax system distinguishes between resource and non-resource companies, with different rate structures and allowance provisions applicable to each category.

Withholding taxes apply to dividends, interest, royalties, and management fees paid to non-residents. The applicable rates are subject to modification under PNG’s double taxation agreements.

Resource Taxation

Mining and petroleum operations in PNG are subject to dedicated fiscal regimes established under the Mining Act and Oil and Gas Act respectively. Resource taxation incorporates a combination of corporate income tax, additional profits tax, royalties, development levies, and state equity participation provisions. The specific fiscal terms applicable to a resource project are determined during the licensing process and codified in the relevant mining development contract or petroleum agreement.

The resource taxation regime is designed to balance sovereign revenue capture with investor returns. InvestPNG provides contextual analysis of resource fiscal terms but does not substitute for project-specific fiscal modelling by qualified advisors.

Investment Incentives

PNG offers several incentive mechanisms relevant to foreign investment:

• Tax Holidays and Concessions — Available for qualifying investments in priority sectors and geographic locations, subject to application and approval.
• Accelerated Depreciation — Enhanced capital allowance provisions for qualifying assets in specified sectors.
• Export Incentives — Tax concessions applicable to export-oriented operations in certain sectors including agriculture and manufacturing.
• Special Economic Zones — Designated zones offering preferential fiscal treatment, streamlined regulatory processes, and infrastructure support for qualifying enterprises.

The availability and terms of incentives vary by sector, location, and investment scale. InvestPNG can advise on incentive applicability during the opportunity engagement process.

Double Taxation Agreements

Papua New Guinea maintains double taxation agreements with several countries to prevent the same income being taxed in both jurisdictions. These agreements typically modify withholding tax rates on cross-border payments and provide mechanisms for resolving tax disputes between treaty partners. The applicable treaty provisions depend on the investor’s country of residence and the structure of the investment.

Goods and Services Tax

PNG operates a Goods and Services Tax on the supply of goods and services within the country. GST registration and compliance obligations apply to businesses exceeding defined turnover thresholds. Import duties apply to goods brought into PNG, with rates varying by product category and origin.

InvestPNG maintains current analysis of the fiscal framework alongside investment law, international agreements, and sector regulations. For tax-specific enquiries related to investment structuring, contact InvestPNG through the engagement portal.
