Everyone is talking about tax. Gen Z should be talking about time.
Whenever governments announce tax reforms, the debate quickly shifts to winners and losers. Who gets a tax cut? Who pays more? Which strategies stop working?
For Gen Z investors, that is probably the wrong question. The biggest driver of your retirement outcome is not the tax rate you might pay on investments in 2066. It is whether you start investing in 2026.
Labor’s latest reforms include a $1,000 instant deduction for workers, a new Working Australians Tax Offset, and changes to capital gains tax. Most commentary has focused on what those changes mean for investors. But it is worth stepping back.
Imagine two 25-year-olds. One starts investing today. The other waits five years. Even if both face exactly the same tax system over their lifetime, the one who starts earlier is likely to retire with significantly more wealth.
That is not a political view. It is simply how compounding works.
Tax policy matters. Investment behaviour matters more.
Why Gen Z Investors Shouldn’t Focus Only on Tax Reform
Tax debates tend to focus on rates. But investors retire on after-tax wealth, not on tax rates. Those are very different things.
A higher tax bill does not automatically mean a worse outcome. A larger investment gain that attracts more tax can still leave you much better off than a smaller gain that attracts less. This matters when thinking about proposed changes to capital gains tax.
Replacing the 50% CGT discount with inflation indexation sounds significant. Many assume it makes growth investing less attractive.
The maths does not always support that conclusion. The key question is not whether tax increases. It is whether you end up with more money after tax. That distinction is often missed in headline commentary.
The Power of Compounding Interest and Tax Deferral
One of the most powerful concepts in investing is tax deferral. If you hold quality assets over long periods, you delay paying tax while your returns compound. That compounding can have a far greater impact than small differences in tax treatment.
For Gen Z, this matters more than most. If you are in your mid-20s, your investment horizon could be 30 to 40 years. Over that timeframe, outcomes are driven by:
- How much you invest
- How consistently you invest
- Your asset allocation
- How you behave during market cycles
- Inflation and market returns over time
- Starting at 25 versus 30
- Increasing contributions by a small amount
- Staying invested in growth assets
- Retiring a few years later
- Building a regular savings plan
- Increasing contributions as income grows
- Maintaining exposure to long-term growth assets
- Staying invested through market cycles
- When you start
- How much you invest
- How consistently you invest
- How you allocate your portfolio
- How you behave when markets move
Tax policy will play a role. But over decades, the effect of compounding tends to dominate.
Investors often spend a lot of effort trying to minimise tax, while paying less attention to the decisions that actually move the needle.
What happens when you run the numbers
Rather than debating policy in the abstract, it is more useful to model outcomes. When you compare different scenarios, a pattern becomes clear. Changes such as:
These often have a larger impact on retirement outcomes than changes in tax settings. This is not about ignoring tax. It is about prioritising what matters most. In many cases, starting earlier or saving a little more delivers a bigger improvement than trying to optimise around policy changes.
Investor Behavior: The Biggest Risk to Long-Term Wealth
For most investors, the biggest risk is not tax. It is behaviour. Delaying investing, reacting to market volatility, switching strategies too often, or chasing short-term trends can do far more damage than any tax change.
This is particularly relevant for younger investors. Focusing heavily on tax optimisation before you have built a consistent investment habit is not especially useful. What matters more is:
These are the decisions that compound over time.
The advantage Gen Z does have
A lot of the generational discussion focuses on what younger Australians lack. Less affordable housing. Smaller starting balances. Fewer years of market gains. All true. But there is one advantage that matters more than most people realise. Time.
Time increases your ability to compound returns, recover from setbacks and benefit from long-term market growth. It is the one factor that cannot be replicated later through tax planning or portfolio tweaks. The earlier you start, the less sensitive your outcome becomes to future policy changes.
Controlling Your Investment Inputs for Better Financial Outcomes
Tax reform will continue. Governments will adjust settings, incentives and thresholds over time. You cannot control that. What you can control are the inputs that drive long-term outcomes:
These decisions are far more likely to determine where you end up.
Tax debates make good headlines. They are less useful for decision-making. If you want a clearer view of what matters, test it using the Nucleus Wealth Retirement Calculator. Compare starting now versus waiting a few years. Adjust your contribution rate. Look at different portfolio mixes. Change your retirement age assumptions.
Most people are surprised by what actually moves the outcome. Because in long-term investing, the biggest driver of your result is rarely the thing getting the most attention. For Gen Z, it is usually much simpler.
Start earlier. Stay consistent. Let compounding do the heavy lifting.
