Kuwait's headline corporate income tax (CIT) rate is 15 flat.
0% - Kuwait levies no personal income tax on individuals.
0% - Kuwait has not yet implemented VAT, despite GCC-wide plans for a unified framework. Confirm current status directly, as this is an area of active policy development.
Kuwait levies no personal income tax, so domestic law has no individual tax residency test. Tax treaties Kuwait has signed do contain residency rules, but these are largely irrelevant for foreign employees working in Kuwait given the absence of a personal income tax regime - they matter mainly for Kuwaiti citizens with income or work assignments in a treaty partner country. Kuwait follows a territorial system: "carrying on trade or business" in/with Kuwait is the main taxability test. Neither individuals nor Kuwait-resident companies wholly owned by Kuwaiti or GCC nationals pay corporate income tax; foreign corporate bodies conducting business or trade in Kuwait (directly or via an agent) pay 15% CIT on profits and capital gains.
Kuwait has no CFC rules.
Resolved in favor of the more authoritative source: PwC's official Kuwait summary describes no formal debt-to-equity ratio - instead, Executive Rule No. 38 gives the Kuwait Tax Authority (DIT) case-by-case discretion to accept interest paid to a financial institution that is fully supported and related to Kuwait operations. A separate, less authoritative GCC-focused technical source cites a 2:1 debt-to-equity ratio for Kuwait, but PwC's Worldwide Tax Summaries is the stronger, more current, and more specific source (naming the actual Executive Rule) and is preferred here.
Kuwait maintains a broad DTT network including Austria, Belgium, Canada, China (1989), Cyprus, Denmark, France, Germany, India, Ireland, Italy, Japan, South Korea, Lebanon, Malta, Mauritius, the Netherlands, Russia, Singapore, Spain, South Africa, Switzerland, and the UK - roughly 20+ named partners, with treaties with several additional countries at various negotiation/ratification stages. Kuwait's treaty network has expanded rapidly in the Gulf recently: it ratified a UAE treaty (Decree No. 7 of 2024, in force from January 2025), signed a Qatar treaty (June 1, 2025, ratified by Kuwait via Decree-Law No. 142 of 2025 and by Qatar via Emiri Decree No. 1 of 2026, pending entry into force), and approved a San Marino treaty (May 5, 2025).
