This guide provides a detailed breakdown of PNG’s income tax system, tax rates, deductions, and important considerations for taxpayers.
1. PNG Income Tax System Overview
The Internal Revenue Commission (IRC) of Papua New Guinea administers the country’s tax system. PNG uses a progressive tax system where higher income earners pay a larger percentage of their income in taxes. The tax year in PNG runs from January 1 to December 31.

3. Residency Rules for Tax Purposes
Your tax obligations in PNG depend on your residency status:

4. Superannuation in Papua New Guinea
PNG has a mandatory superannuation system called the Nambawan Super and Nasfund. All employees must contribute to a superannuation fund:

The superannuation system in PNG is designed to provide retirement benefits and is an important consideration when calculating take-home pay.

6. How to Calculate Your Income Tax
To calculate your income tax in PNG, follow these steps:
- Determine your residency status: This affects your tax rates and eligibility for the tax-free threshold.
- Calculate your assessable income: This includes salary, bonuses, investment income, and other taxable amounts.
- Subtract allowable deductions: Reduce your assessable income by claiming eligible work-related expenses and other deductions.
- Apply the tax rates: Use the progressive tax table to calculate tax on your taxable income.
- Subtract any tax offsets: Apply any rebates you’re eligible for.
- Calculate Medicare levy (if applicable): PNG doesn’t have a Medicare system like Australia, but there may be other levies.
- Determine your net tax payable: This is the amount that will be withheld from your pay or that you’ll need to pay at tax time.
Our calculator at the top of this page performs all these calculations automatically based on the information you provide.
7. PAYE (Pay As You Earn) System
PNG operates a PAYE system where employers withhold tax from employees’ salaries and remit it to the IRC. This means:
- You don’t need to make separate tax payments during the year
- Your employer calculates and withholds the correct amount based on your declared tax file number and circumstances
- You may receive a tax refund if too much was withheld, or have a tax bill if not enough was withheld
- You still need to lodge an annual tax return to reconcile your tax position
8. Important Tax Dates
| Date | Description |
|---|---|
| March 31 | Deadline for employers to provide PAYE summaries to employees |
| April 30 | Deadline for lodging individual tax returns (unless you use a tax agent) |
| June 30 | Deadline for paying any tax owed from your return (if lodged by April 30) |
| Monthly (7th of each month) | PAYE withholding payments due from employers |
9. Tax Planning Strategies
Legal tax planning can help you minimize your tax liability while remaining compliant with PNG tax laws. Consider these strategies:
- Salary sacrificing: Redirect part of your pre-tax salary into superannuation (within contribution caps)
- Maximize deductions: Keep receipts and records of all work-related expenses
- Income splitting: If you have a family business, consider distributing income among family members
- Timing of income: If possible, defer income to a lower-income year
- Investment structuring: Consider tax-effective investment structures
- Charitable giving: Donations to approved charities can provide tax benefits
Always consult with a qualified tax advisor before implementing any tax planning strategies to ensure they’re appropriate for your situation and compliant with PNG tax laws.
10. Common Tax Mistakes to Avoid
Many taxpayers in PNG make avoidable mistakes that can lead to penalties or missed opportunities:
- Not keeping proper records: Without receipts, you can’t claim deductions
- Missing the lodgment deadline: Late returns attract penalties
- Not declaring all income: The IRC has sophisticated data-matching capabilities
- Claiming ineligible deductions: Only claim what you’re entitled to
- Ignoring residency rules: Your tax obligations change based on residency status
- Not reviewing your PAYE: Check your payslips to ensure correct withholding
- Forgetting about capital gains: Investment property sales and other capital gains are taxable
11. Comparing PNG Tax Rates with Regional Neighbors
How does PNG’s tax system compare with other Pacific nations? Here’s a comparison of top marginal tax rates:

| Australia | 45% | Over AUD 180,000 | AUD 18,200 |
| New Zealand | 39% | Over NZD 180,000 | NZD 14,000 |

16. Case Study: Tax Calculation Example
Let’s look at a practical example of how tax is calculated for a PNG resident:
Scenario: John is a PNG resident earning PGK 85,000 per year. He has PGK 2,000 in work-related deductions and contributes 7.5% to superannuation.
- Gross income: PGK 85,000
- Less deductions: PGK 2,000
- Taxable income: PGK 83,000
- Tax calculation:
- First PGK 12,500: PGK 0
- Next PGK 7,500 (12,501-20,000): PGK 1,800 (24%)
- Next PGK 15,000 (20,001-35,000): PGK 4,500 (30%)
- Next PGK 35,000 (35,001-70,000): PGK 12,250 (35%)
- Remaining PGK 13,000 (70,001-83,000): PGK 5,200 (40%)
- Total tax: PGK 23,750
- Superannuation: PGK 6,375 (7.5% of PGK 85,000)
- Net income: PGK 85,000 – PGK 23,750 – PGK 6,375 = PGK 54,875
- Effective tax rate: 27.94% (PGK 23,750 / PGK 85,000)
