New Zealand FAQs
What bright-line period is used?
The calculator uses the current 2-year bright-line period for sales on or after 1 July 2024.
What dates should I use?
For standard transactions, start is generally title transfer or settlement date, and end is generally the binding sale and purchase agreement date.
What if I sold before 1 July 2024?
Older 5-year and 10-year rules may apply. This calculator flags those as legacy rules rather than giving a full decision.
What if the property was my main home?
The bright-line test generally does not apply when the main-home criteria are met.
