What is Residential Land Withholding Tax (RLWT) and Bright-Line Test?
New Zealand does not have a general capital gains tax, but the bright-line test taxes gains on residential property sold within 2 years of acquisition as ordinary income. RLWT (5% to 33% depending on gain) must be withheld by the purchaser when the vendor is an offshore person.
Current Rate (1 April to 31 March)
Bright-line: 2 years (from 1 July 2024). RLWT rate: 5% of purchase price if offshore vendor. Standard income tax rates on the resulting gain.
Example
An investor buys a NZ residential property for NZD 800,000 in August 2024 and sells for NZD 950,000 in March 2026 (18 months later, within the 2-year bright-line). The NZD 150,000 gain is taxable income. If they are in the 33% tax bracket, they pay NZD 49,500 in income tax on the gain.
How Residential Land Withholding Tax (RLWT) and Bright-Line Test works in New Zealand
New Zealand is unusual among developed economies in not having a general capital gains tax (CGT) on investment assets. However, the bright-line test is a targeted CGT equivalent applying specifically to residential property, and various other provisions tax property gains where the seller intended to resell at purchase, or where the property is trading stock.
**Bright-Line Test History** The bright-line test was introduced on 1 October 2015 with a 2-year period. It was extended to 5 years for properties acquired from 29 March 2018 and to 10 years for properties acquired from 27 March 2021. From 1 July 2024, the period reverted to 2 years, applying to residential property acquired on or after that date. This means buyers from July 2024 onward face a 2-year test, while existing owners who bought between March 2021 and June 2024 remain subject to the 10-year rule.
**What Is Residential Land** The bright-line test applies to residential land: land that has a dwelling on it or that is capable of having a dwelling built on it. It does not apply to: the seller's main home (the main home exemption, with limits); property inherited from a deceased estate; relationship property transfers under the Property (Relationships) Act; and property owned by certain categories of local authority.
**New Build Exemption** New builds (properties that have received a code compliance certificate within the last 2 years at the time of acquisition) are subject to a 2-year bright-line period regardless of when they were acquired. This exception was intended to encourage new housing construction.
**Residential Land Withholding Tax (RLWT)** When an offshore person sells NZ residential property subject to the bright-line test, the purchaser (or their conveyancer) must withhold RLWT at 5% of the purchase price (not the gain) and pay it to IRD. The offshore seller then files an income tax return for the year and the RLWT is credited against their final tax liability. RLWT is a compliance mechanism to ensure non-residents pay NZ tax on bright-line gains.
**Tax on the Gain** For NZ residents subject to the bright-line test, the gain (sale price less cost, less acquisition and disposal costs) is included in ordinary income and taxed at the seller's marginal income tax rate. Unlike some countries, NZ does not apply a reduced CGT rate; it is simply income. Losses from a bright-line disposal can be offset against other income only if the taxpayer has other bright-line gains in the same year; otherwise they are ring-fenced.
