Stock options have long been a powerful tool for attracting and retaining talent in Australia’s tech and startup sectors. While incentive stock options (ISOs) often grab headlines, non-qualified stock options (NSOs) are increasingly common in local compensation packages. With 2025 ushering in fresh tax guidance and market volatility, it’s crucial for founders, employees, and investors to get to grips with how NSOs really work in Australia — and how they differ from other equity incentives.
Non-qualified stock options (NSOs) give employees or contractors the right to buy company shares at a fixed price, usually called the exercise or strike price, for a set period. Unlike ISOs — which are limited to employees and offer certain tax advantages in some countries — NSOs can be granted to anyone, including consultants and advisors. The ‘non-qualified’ label simply means they don’t qualify for special tax treatment under US law, but in Australia, the focus is squarely on how and when you pay tax.
For example, if you join an Australian fintech startup and receive 10,000 NSOs at a $2 exercise price, you can buy up to 10,000 shares for $2 each once the options vest — regardless of what the shares are worth when you exercise them.
Tax treatment is where NSOs get interesting — and sometimes confusing. The Australian Taxation Office (ATO) updated its guidance in late 2024, so 2025 brings some important nuances:
Let’s say you exercise your 10,000 NSOs in December 2025, when the share price is $5. You’ll be taxed on the $3 per share discount ($5 market price – $2 exercise price) — that’s $30,000 of assessable income, reported on your tax return. If you later sell your shares at $8 each, the $3 difference ($8 – $5) is subject to CGT. Holding the shares for more than 12 months could qualify you for the 50% CGT discount.
NSOs are especially relevant for:
With the Australian tech sector maturing and unicorn valuations under more scrutiny in 2025, many startups are tweaking option plans to ensure they’re both attractive and tax-efficient. For employees, it’s essential to understand vesting terms, exercise windows, and the possible tax bills that can arise — especially if your company is acquired or goes public.
So how do you make the most of your NSOs? Here are some practical strategies for 2025:
Non-qualified stock options are a powerful part of Australia’s modern compensation landscape, especially for startups and scale-ups. With the ATO’s 2025 ESS reforms and increased market scrutiny, understanding how NSOs work — and how they’re taxed — is more important than ever. Whether you’re a founder, employee, or advisor, getting across the fine print now can help you unlock real value from your equity package in the years ahead.
