Leaving New Zealand: What to Know
Tax Departure Rules for New Zealand
New Zealand does not impose a departure or exit tax on individuals. There are no deemed disposal rules when ceasing NZ tax residency. However, the transitional residency rules for arriving migrants mean some people may still have NZ tax obligations for up to 4 years after arriving.
Capital gains considerations: New Zealand has no general capital gains tax. However, the bright-line property test taxes gains on residential property sold within specific holding periods (currently 2 years, or 5/10 years for some properties acquired earlier). Non-residents selling NZ property remain subject to the bright-line test.
Practical steps when leaving: Notify Inland Revenue of your departure and non-resident status, apply for KiwiSaver withdrawal after 1 year abroad, and review any NZ rental property obligations — non-residents have limited interest deductibility on residential rental properties.
