Why super is still a tax-effective investment
In brief
Super remains one of the most tax-effective ways for Australians to invest for retirement. The May 2026 Federal Budget changed how some investments outside super are taxed, but super's tax advantages remain unchanged.
Why this matters
Understanding how your super gets taxed puts you in a stronger position to make confident decisions about your retirement savings. You don't need to react to every budget headline, but it's worth knowing why super continues to work hard for you, whatever life stage you are in before retirement.
What do recent budget changes mean for super?
The May (2026–27) Federal Budget made some significant changes to the tax treatment of investments held outside of super, including reforms to capital gains tax and negative gearing. The aim of these changes was to tip the tax system back in favour of super, and to make housing more affordable for working Australians.
Here are the top superannuation-related budget announcements:
1. Capital gains tax (CGT): Super unaffected
- From 1 July 2027, the 50% CGT discount on investments held outside super will be replaced with cost-base indexation and a 30% minimum tax on real capital gains.
- Super's CGT arrangements are untouched, with the 33% CGT discount inside super preserved. Transitional arrangements also mean that existing investments outside super are largely protected from the new rules.
2. Negative gearing: Limited to new builds, existing investors protected
- From 1 July 2027, negative gearing on residential property will only apply to new builds. Properties already held are exempt. This change doesn't affect your super.
3. Discretionary trusts: Super explicitly excluded
- A 30% minimum tax will apply to discretionary trusts from 1 July 2028. Complying superannuation funds are explicitly excluded from this measure.
Think of super as a long-term money partner. While you're working, a portion of your earnings is paid into your super account under Australia's compulsory super system. Your super fund then invests that money with the goal of growing your balance over time.
Then, when you retire, your super balance becomes a source of regular income, money to use to live the life you have worked hard towards.
And here’s where super really earns its keep: when it comes to tax. Both your contributions and your investment returns are taxed at a lower rate. That’s where the power of super stands out.
How contributions are taxed
Concessional contributions include things like your employer's compulsory contributions, salary sacrifice, and personal contributions you claim as a tax deduction, which are generally taxed at just 15% when they enter your super. For most working Australians, that's well below their personal marginal tax rate.
To put that in perspective: if you earn $80,000, your marginal tax rate is 32.5%. Direct that money into super as a concessional contribution, and it's generally taxed at less than half that rate. That difference adds up in super, year after year.
Non-concessional contributions work differently. Because they come from money you've already paid income tax on, they generally aren't taxed again when they enter your super. There's no upfront tax deduction, but your money still grows in super's tax-effective environment. Because both concessional and non-concessional contributions face annual limits, it’s important to know where these limits are, as additional tax may apply if you exceed them. For more information, visit the ATO website. It may also make sense to consult a financial adviser or a registered tax agent to help navigate staying within the set limits.
Investing inside super vs. outside super in accumulation phase
One of super's biggest advantages is its tax treatment. Compared with investing outside super, you may benefit from:
- Lower tax on eligible contributions.
- Lower tax on investment earnings while your savings grow.
- Lower tax on long-term capital gains.
Why regular super contributions matter
Understanding how super is taxed is one thing, putting it to work is another.
One of the most powerful things you can do for your retirement savings isn't a one-off decision at tax time, it's the habit of contributing consistently all year-round.
The power of compounding
When your super fund generates investment returns, those returns are reinvested. Then they generate returns of their own. Over time, this compounding effect can make a significant difference to your final balance.

The earlier and more regularly you contribute, the more opportunity compounding has to work in your favour. A small additional contribution made today is worth more than the same contribution made five years from now.
Over time, this compounding effect can make a significant difference to your final balance.
What could you do next?
You don't need to overhaul everything at once, but it may be worth taking a moment to review where you're at and check in on whether there are simple steps you could take to make your super work a little harder for you.
- Review your current contributions: Check what's going into your super each pay cycle. Is it what you'd expect? Payday Super rolled out from 1 July 2026, making it easier to track your contributions.
- Understand the contribution caps: There are limits on how much you can contribute in a tax-effective way each year. Read more about concessional, non-concessional and contribution caps.
- Explore salary sacrifice or voluntary contributions: If you have a little more capacity, directing some of your before-tax pay into super through your employer can be a simple and tax-effective way to grow your balance. Learn more about salary sacrificing.
- Voluntary after-tax contributions: These are another option if salary sacrifice isn't available to you. Get more information about ways you can grow your super.
- Consider speaking with a financial adviser: Everyone's situation is different. If you'd like personalised guidance on your super strategy, a financial adviser can help you make decisions that are right for you specifically.
- Use our retirement calculator: Retirement calculators can be used to estimate how much income your super could provide in retirement and see how different choices today could shape your future.
And of course, where your money is invested matters too. Growing your retirement savings and investing in a better world isn’t a trade-off, because at Australian Ethical, they’re the same thing.
