New Zealand Startup Equity & ESOP Tax Guide (2026)

Eligible vs Non-Eligible Schemes

Eligible schemes: The first $5,000 of benefit is tax-exempt (subject to conditions). Non-eligible schemes: The full benefit is treated as employment income and taxed at your marginal rate.

Tax on exercise of options

When you exercise options, the difference between FMV at exercise and exercise price is generally taxable as employment income. This is known as the 'discount' or 'benefit'.

Tax on disposal of shares

When you sell the shares, any gain between FMV at exercise and sale price is generally taxable as income or capital gain, depending on your circumstances.

The $5,000 exemption for eligible schemes

Eligible schemes can exempt the first $5,000 of benefit from tax each year. The exemption applies to the total benefit across all schemes in the income year.

FIF (Foreign Investment Fund) rules

FIF rules may apply if you hold shares in a foreign company. The 5% deemed rate method is commonly used. This calculator includes FIF considerations.

Vesting and tax timing

Tax is generally triggered when options are exercised, not when they vest. However, some schemes may have tax at vesting if the shares are not 'forfeitable'.

Founders vs employees

Founders may have different tax treatment, including the potential application of FIF rules and different capital gains treatment.

IRD record keeping requirements

Keep records of grant dates, exercise dates, FMV at grant and exercise, and sale details. IRD may require these for tax returns.

Startup equity strategy

Consider the timing of exercise and sale to optimise tax. Exercising early may reduce employment income tax but increase capital gains tax.
