Which Bright-Line Rule Applies to You? 2, 5 and 10-Year Rules
What is the bright-line test in New Zealand?
The bright-line test is New Zealand's main rule for taxing residential property capital gains. If you sell a residential property within the bright-line period after acquiring it, any profit is taxable income unless an exclusion (main home, business premises, farmland) or rollover relief applies. For properties sold on or after 1 July 2024, the bright-line period is 2 years regardless of when you acquired the property. For earlier sales, the period depended on the acquisition date and was either 2, 5, or 10 years.
What was the bright-line period before 1 July 2024?
It depended on when you acquired the property. Properties acquired 1 October 2015 to 28 March 2018 had a 2-year test. Properties acquired 29 March 2018 to 26 March 2021 had a 5-year test. Properties acquired on or after 27 March 2021 had a 10-year test, with a 5-year carve-out for new builds. These periods still matter if you sold a property before 1 July 2024 and are filing a late return, amending, or being audited on a historical sale.
How does the main home exclusion work now?
For sales on or after 1 July 2024, the main home exclusion applies if you used the property as your main home for MORE than 50% of the bright-line period AND used more than 50% of the area as your main home. If either test fails, you don't qualify. A 12-month absence buffer is available (overseas trips, renovations). The exclusion cannot be used more than twice in any 2-year period, to prevent serial flipping. For sales before 1 July 2024 acquired after 27 March 2021, a similar 50/50 test applied. For sales acquired before 27 March 2021, an all-or-nothing majority-use test applied.
What counts as a new build for bright-line purposes?
A property qualifies as a new build if its Code Compliance Certificate (CCC) was issued on or after 27 March 2020. Under the old 10-year rule (for properties acquired 27 March 2021 to 30 June 2024), new builds had a shorter 5-year bright-line period. Under the current 2-year rule, the new build distinction is no longer relevant for bright-line purposes, but it still matters for interest deductibility (new builds had uninterrupted 100% deductibility throughout the phase-out period).
What is rollover relief?
Rollover relief allows certain transfers between related parties to happen without resetting the bright-line clock or triggering tax. For sales on or after 1 July 2024, rollover relief is available for transfers between associated persons (spouses, partners, parents and children, certain family trusts, look-through companies, partnerships). The transferee 'inherits' the transferor's acquisition date and cost base. Without rollover relief, a transfer to a trust or family member counts as a disposal at market value and can trigger the bright-line test even though no external sale occurred.

Does the bright-line test apply to my family home?
The main home you live in is generally excluded, subject to conditions, so it usually does not apply to your own home.

The relevant dates are specific legal dates and are often the dates of the binding sale and purchase agreements rather than settlement. Because this affects whether you are inside the window, confirm the correct dates with your lawyer or accountant.

Usually not. The main home is generally excluded, and other exceptions exist for inherited property and relationship property. This tool only checks timing, so confirm whether an exclusion applies before relying on the result.

Crypto Cost Basis FIFO Calculator NZ
Is cryptocurrency taxed in New Zealand?
Yes. Inland Revenue treats crypto-assets as property, and gains from selling them are usually taxable income at your marginal rate, because most people acquire them with the purpose of selling. There is no separate capital gains tax, but the gain is still taxed as income.
What is FIFO cost basis?
First in, first out matches a sale against your earliest purchases first. The cost basis of the units sold is the price you paid for those earliest coins, which Inland Revenue accepts as a valuation method.
How is the gain taxed?
The taxable gain is the sale proceeds less the cost basis of the units sold and any fees. That gain is added to your income and taxed at your marginal rate. Keep good records of every buy and sell.
NZ Dividend Tax Calculator 2025-26
What are imputation credits on NZ dividends?
When a New Zealand company pays 28% corporate income tax on its profits, it can attach imputation credits to dividends paid to shareholders. These credits represent the tax already paid at the company level. The shareholder grosses up the cash dividend to the pre-tax amount, pays personal income tax at their marginal rate on the gross figure, then deducts the imputation credits. This prevents the same income from being taxed twice.
What happens if my tax rate is lower than 28%?
If your personal marginal rate is below 28%, the imputation credits exceed your tax liability on the dividend, so you receive a tax refund for the difference. For example, at 17.5% on a fully imputed $1,000 gross dividend, your tax is $175 against $280 of credits, giving a $105 refund. You claim this through your IR3 income tax return.
Do I need to declare dividend income in my NZ tax return?
Yes. Fully imputed dividends from New Zealand companies must be declared in your IR3 return. Inland Revenue uses the gross dividend (the cash amount plus imputation credits) as your assessable income, then credits the imputation credits against your tax liability. Any RWT withheld by the company is also credited against the amount you owe.
FIF Method Comparison Calculator NZ
What are the FIF tax methods?
The two common methods for individuals are the fair dividend rate, which taxes 5% of the opening market value, and the comparative value, which taxes the actual gain plus dividends. Individuals can generally use the lower of the two across their portfolio.
Which FIF method should I use?
Generally the one giving the lower taxable income, which individuals can usually choose across their whole FIF portfolio. In a year of strong gains the fair dividend rate is often lower; in a flat or down year the comparative value can be lower.
When do the FIF rules apply?
The FIF rules generally apply when your overseas shares cost more than a threshold set by Inland Revenue. Below that, normal dividend taxation applies. Check the current threshold and rules, as the FIF area is complex.
FIF De Minimis $50k Threshold Checker NZ
What is the FIF de minimis threshold?
If the total cost of your foreign shares is 50,000 dollars or less, you are under the de minimis threshold and the FIF rules do not apply. You are simply taxed on dividends. Once the cost exceeds 50,000 dollars, the FIF rules apply to the whole holding.
Is the threshold based on cost or value?
It is based on the cost of the shares, what you paid, not their current market value. So your holding can grow well above 50,000 dollars in value and still be under the threshold if the original cost was 50,000 dollars or less.
Does the threshold apply to all foreign shares?
It applies to most offshore shares held by individuals. Certain Australian listed shares are exempt from FIF. The de minimis test is per person, so partners are tested separately. Check the detail with IRD or an accountant.
FIF Rules Explained Calculator NZ
What are the FDR and CV methods?
Fair dividend rate (FDR) taxes you on 5 percent of the opening market value of your foreign shares each year, regardless of actual return. Comparative value (CV) taxes the actual economic return, being the rise in value plus distributions. Individuals can use the lower of the two.
Which method should I use?
You generally use whichever gives the lower FIF income. In a strong year FDR is usually lower; in a flat or falling year CV can be lower, even zero, because FIF income cannot be negative. This tool works out both and shows the lower.
Do the FIF rules even apply to me?
Only if the cost of your foreign shares is over 50,000 dollars. Below that, the de minimis threshold means the FIF rules do not apply and you are simply taxed on dividends. Check the threshold first.
Proposed Rental Income Tax Calculator NZ
Is rental income already taxed in New Zealand?
Yes. Rental profit is taxed as income at your marginal rate. You declare the rent, deduct allowable expenses, and the profit is added to your other income. This calculator models an additional surcharge on top of that, which does not exist.
Why does the base matter more than the rate?
Because a rental can have large rent and small profit. A 5 percent charge on gross rent can be more than double a 5 percent charge on net profit for the same property, and a loss-making property pays nothing on a profit base but still pays on a gross base.
Can I deduct mortgage interest?
Interest deductibility on residential rental property has changed several times in recent years, so check the current rules before entering interest as an expense. This calculator takes whatever expenses figure you enter and does not decide deductibility for you.
