Rental loss ring-fencing
New Zealand rule that prevents residential rental losses from being offset against other income such as salary or wages. Losses are quarantined and carried forward to offset future rental profits.
Since the 2019–20 income year, residential rental losses in New Zealand cannot be used to reduce tax on other income. Any loss is “ring-fenced” and carried forward to offset rental profit or taxable land sale income in later years.
The rule applies on a portfolio basis by default — losses from one property can offset profits from another in the same portfolio — but taxpayers can elect property-by-property treatment. Certain categories, including mixed-use holiday homes and land that is taxable on sale under other rules, are excluded.
Ring-fencing is administered alongside the interest deductibility rules and the bright-line test, and all three need to be considered together when modelling after-tax returns on a New Zealand rental.
