What this value means
New statute, in force from 1 January 2026. Section 163 of the Income Tax Act 2025 REPEALS the Income Tax Act 1959, the Income Tax (Rates) Act 1975, the Income Tax (Salary and Wages Tax) (Rates) Act 1979, the Income Tax, Dividend (Withholding) Tax and Interest (Withholding) Tax Rates Act 1984 and the Income Tax (International Agreements) Act 1997 — so any citation to those Acts for a 2026 rate is stale. The rewrite halved the section count and cut length by roughly 80%; the Income Tax Regulation 2025 commenced with it (2026 National Budget Vol 1 §5.2.5). SPECIAL COMPANY RATES in the same Clause (5), which the flat 30% headline hides: approved superannuation fund 25%; non-approved superannuation fund 30%; and, for a financial institution licensed as a commercial bank under the Banks and Financial Institutions Act 2000, a SPLIT rate — 35% on taxable income under K300 million (fiscal 2026 and future years) plus a surcharge tier on taxable income OVER K300 million that steps down annually: 43% in FY2026, 42% FY2027, 41% FY2028, 40% FY2029, 39% FY2030, 38% FY2031, 37% FY2032, 36% FY2033 and 35% from FY2034. A trust other than a deceased estate in its first 3 years is taxed at 42%. Related headline rates in Schedule 1 Part I: capital gains tax 15%, additional profits tax 30%, international transportation income tax 2.4%; non-resident tax 3% on insurance premiums, 10% on entertainers, 10%/30% on royalties, 15% on interest, technical fees, annuities and natural resource amounts, and 15% on dividends and on repatriated profits of a PNG permanent establishment. Small business: a flat small business tax amount of K250, or K62.50 plus 2% of quarterly turnover above K15,000, applies below the K60,000 threshold specified in Schedule 1 Part II. CORRECTION vs. widely circulated summaries: professional tax digests still quote a 48% rate for non-resident companies. That was the branch rate under the repealed 1959 regime; the Income Tax Act 2025 Schedule 1 Part I Clause (5) has no non-resident company rate — 'any other company' is 30%, with the 15% repatriated-profits withholding under Clause (9)(f) doing the extra work. ACCESS PROBLEMS, both serious: (1) parliament.gov.pg presents an EXPIRED TLS CERTIFICATE, so ordinary fetchers refuse the connection; retrieval required disabling certificate verification. (2) The certified Act PDF is a 128-page SCAN with no text layer at all — zero extractable characters — so the rate schedules (printed pages 100-103) must be read visually or OCR'd. (3) The Internal Revenue Commission's site (irc.gov.pg) returns HTTP 403 to every external request including its homepage, so the IRC cannot be used as a watch target.
