Superannuation: The Tax Strategy Most Business Owners Underuse (and How to Get It Right Before the Rules Change)

We know, Superannuation doesn’t exactly scream “exciting!” For many business owners, it just sits in the background. One other item on a list of things that you’ll “deal with later.”

But what most people fail to realise is that superannuation is one of the most powerful and under-utilised tax strategies available in Australia. And with changes to capital gains tax on the horizon, the gap between those who use it strategically and those who don’t is about to widen.

So, let’s break it down in simple terms, what it is, how it works, and where the real opportunities sit especially as we see changes within the sector.

Superannuation Isn’t Just Retirement Savings

Most people see superannuation as a long-term savings account. Smart business owners see it differently.

They see it as:

• A tax minimisation tool
• A way to smooth income across years
• A strategic vehicle to move wealth into a lower-tax environment

Because inside super, the tax rules are very different.

The Two Ways to Use Super Strategically

1. Concessional Contributions (Before-Tax Money)

This is where real tax leverage can be found.

Concessional contributions include:

• Employer super (currently 12%)
• Salary sacrifice
• Personal deductible contributions

These contributions are taxed at 15% inside super, instead of your marginal tax rate.

So, if you’re earning within the 30%, 37% or 45% tax bracket, you can immediately see the difference! And that’s without the 2% Medicare levy on top of these rates.

Example

Liam earns $180,000 through his company and therefore sits in the 37% personal income tax bracket.

He contributes $20,000 into super.

Instead of paying 39% tax (with the Medicare levy), that money is taxed at 15%.

That’s a 24% tax saving on that portion of income.

Now multiply that across years… and you start to see why this matters.

The Catch? There’s Always One

Yes, there is a catch. There’s a cap.

You can only contribute $30,000 per year (including employer contributions) into super as concessional contributions.

But this is where it gets interesting…

Carry-Forward Contributions: The Strategy Most People Miss

If you haven’t used your full concessional cap in previous years, you can carry forward unused amounts for up to five years.

This means:

• You may be able to contribute well above $30,000 in a single year
• And claim a larger tax deduction when it matters most

Conditions:

• Your total super balance must be under $500,000
• You must have unused caps from previous years

Why This Matters for Business Owners

Anyone who has been in business for a few years knows that income isn’t always consistent. Some years are steady, some years are big and some you might just scrape through.

And that’s exactly where this strategy takes centre stage.

Example:

Let’s say Liam has a strong year.

Instead of contributing $30,000, he:

• Uses carry-forward caps
• Contributes $60,000

This reduces his taxable income significantly in that high-profit year.

It’s not just tax saving, it’s tax timing. Timing is everything.

2. Non-Concessional Contributions (After-Tax Money)

These are contributions made into your super fund using money you’ve already paid tax on. There are some rules here:

• You can only contribute a maximum of $120,000 per year (but you can bring it forward and pay $360,000 in year 1 and $0 in years 2 and 3)
• No immediate tax deduction but you also aren’t taxed for what you contribute into the fund
• Earnings inside super are taxed at 15% (or lower in retirement)

This strategy is less about immediate tax savings and more about:

• Long-term wealth accumulation
• Increasing the tax-free component which has implications when you’re able to take it out.

“Pay It Forward”: Using Super to Offset Capital Gains Tax

Here’s where using Superannuation as a strategy gets really interesting.

Let’s say you:

• Sell an investment property
• Or dispose of a business asset

You trigger Capital Gains Tax (CGT).

Now, if you’ve held that asset for more than 12 months, you currently get a 50% CGT discount. Meaning that you pay capital gains tax on 50% on the gain of that sale.

But there’s talk of that being reduced to as low as 25%, potentially as early as May (keep an eye on the budget!). But don’t panic because if this is the outcome, it is likely to be phased in over several years.

Either way, the tax on those gains could increase significantly over the coming years.

What Can You Do?

You can “pay it forward” into super.

By making a concessional contribution in the same financial year:

• You reduce your taxable income
• Which helps offset the capital gain

Example:

Let’s imagine your income puts you in the top tax bracket and you are taxed at a rate of 47%. You bought an investment property for $650,000 and 7 years later sell it for $1.1m. That’s a capital gain of $450,000. 

That’s a difference of $52,875 in tax to be paid.

While that feels like a big difference in tax you are now paying to the ATO, you can still make a strategic super contribution to reduce your overall tax liability as outlined above.

This is where planning matters.

Because once the financial year closes… so does the opportunity.

Timing Is the Strategy

If there’s one takeaway from all of this, it’s this:

Super is less about how much and more about when.

• A big income year? → Increase contributions
• Sold an asset before or after May? → Offset with super
• Inconsistent profits? → Use carry-forward caps

The people who get the most out of super aren’t necessarily contributing more.

They’re just using it more strategically.

SMSFs and Bringing Contributions Forward

For those with a Self-Managed Super Fund (SMSF) under the right conditions, you may be able to:

• Bring forward non-concessional contributions
• Contribute multiple years’ worth in one hit

This can be particularly useful if:

• You’ve had a one-off windfall
• Sold a property
• Or experienced an unusually strong income year

Again… it comes back to timing. While there may not always be an opportunity for  tax savings, it does provide the means to increase your superannuation and build your wealth for retirement.  

What’s Changing: Division 296

From March 2026, Division 296 taxreforms set to impact individuals with larger super balances.

While the detail continues to evolve, the intent is clear:

• Higher balances may be taxed more heavily
• The concessional nature of super will reduce at the top end

Which means:

• The window to maximise current rules may be narrowing
• Strategic contributions now could become even more valuable

So Where Does This Leave You?

Super isn’t a set-and-forget system. Used passively, it does its job. Used strategically, it becomes a powerful tool to:

• Reduce tax
• Build long-term wealth
• Create flexibility across financial years

The Real Question

Most business owners aren’t under-utilising super because they don’t care.

They’re under-utilising it because:

• They don’t know what’s possible
• Or they haven’t had the right conversation with their accountant at the right time

In a world where tax rules shift, margins tighten, and timing matters more than ever Superannuation quietly sits there as one of the few levers you can still pull.

The question is:

Are you using it as a default or as a tax saving and wealth generation strategy?

If you’re heading into a strong year, selling an asset, or simply want to understand what’s possible, it’s worth getting clear on how superannuation fits into your broader tax plan.
