What is superannuation?

Superannuation (super) is simply money set aside for your retirement in a tax-favoured environment.

Money that goes into super (within the rules) is taxed at 15% in the fund instead of your usual marginal tax rate.
Over time, that money is invested and grows, ideally giving you more retirement savings for each dollar you put in.

When you’re an employee, your boss handles this through compulsory super guarantee (SG) payments. When you’re a sole trader, there’s no boss, so if you want super, you have to make it happen yourself.

Do sole traders have to pay super?

Short answer: No, you’re not legally required to pay super for yourself as a sole trader.

According to the ATO:

If you’re self-employed as a sole trader or in a partnership, you don’t have to pay a super guarantee (SG) for yourself.
You can choose to make personal super contributions into a fund in your name.

However:

If you hire employees (or certain contractors who are mainly providing labour), you must pay SG for them, just like any other employer.

So think of it like this:

No legal SG obligation for your own super as a sole trader.

Clear legal SG obligation for your eligible staff and labour-only contractors.

How does superannuation work differently for sole traders vs companies?

Your business structure changes how super works:

Sole trader / partnership
- You’re not an “employee” of your business.
- No compulsory SG for yourself.
- You make personal contributions to super if you choose to.
Company (Pty Ltd)
- If you pay yourself a wage or salary from the company, the company generally has to pay SG at the current rate (12% from 1 July 2025) on those earnings.

Many business owners move from sole trader to company as they grow, and their super obligations change with that move, worth keeping in mind.

When does it make sense to pay yourself super as a sole trader?

If it’s not compulsory, why would you pay super at all?

Here are the most common situations where it makes financial sense:

You’ve had a strong profit year
- You’re paying a higher marginal tax rate.
- Making personal contributions to super and claiming a deduction can shift income into a 15% tax environment, up to the concessional cap.
Your income fluctuates year to year
- With carry-forward concessional contributions, if your total super balance is under $500,000, you may be able to use unused concessional cap amounts from the previous five years in a good year.
You’re on low–middle income and want a boost
- If you make after-tax (non-concessional) contributions and don’t claim a deduction on them, you may be eligible for the government co-contribution (up to $500) if your income is under certain thresholds.
You’re thinking long-term (early retirement or lifestyle shift)
- If you plan to cut back work earlier, consistently contributing to super in your 30s, 40s and 50s can give you a much stronger retirement base.
You want discipline with your money
- Super can act as a forced savings plan. Once it’s in super, it’s generally locked away until retirement age, which can help if you tend to spend surplus cash.

How Much Does It Cost to Set Up as a Sole Trader in Australia?

How do you pay super as a sole trader (step-by-step)?

Here’s the practical part, how to actually pay super as a sole trader.

Step 1: Choose or confirm your super fund

If you’ve ever been employed, you likely already have a super fund. You can:

Keep using that existing fund, or
Open a new retail, industry or self-managed super fund (SMSF), depending on your needs and advice.

Most sole traders stick with a mainstream fund for simplicity.

Step 2: Make sure your fund has your TFN

Give your fund your tax file number (TFN) if they don’t already have it. If they don’t:

They may reject your personal contributions, or
Charge extra tax (up to an additional 32%) on contributions.

Your TFN also helps ensure your contributions are matched correctly and reported to the ATO.

Step 3: Decide how much and how often to contribute

There’s no fixed rule, but some common approaches are:

Match the employer SG rate
- From 1 July 2025, employers must contribute 12% of ordinary time earnings for employees.
- Many sole traders use that as a benchmark for their own contributions when cash flow allows.
Set a fixed monthly amount
- For example: “I’ll put $500/month into super” and review annually.

Either way, check your numbers against the current concessional contributions cap:

From 1 July 2024, the general concessional cap is $30,000 per year for most people.

Remember: all concessional contributions count towards the cap:

Employer SG (if you have any from other jobs)
Salary sacrifice
Personal contributions you claim as a deduction.

Step 4: Pay into your super fund

Once you know how much you’re contributing:

Log in to your super fund or check your member statement.
Find their BPay, direct debit or EFT details.
Make a transfer from your personal or business bank account.
Include your member number and any required reference so they can identify it.

From the fund’s perspective, this is a personal contribution.

Step 5: Decide if you’ll claim a tax deduction

You have two broad options:

Treat it as a concessional (before-tax) contribution
- You claim a tax deduction in your personal return.
- The contribution is taxed at 15% in the fund, rather than your marginal rate.
Treat it as a non-concessional (after-tax) contribution
- You don’t claim a deduction.
- It goes into super from money you’ve already paid tax on.
- These count towards the non-concessional cap (currently $120,000 a year, or up to $360,000 over three years using the bring-forward rule, subject to eligibility).

The choice affects your tax position, caps, and eligibility for the government co-contribution, so it’s smart to check with your accountant.

Step 6: Lodge a ‘Notice of intent to claim a deduction’

If you want to claim a tax deduction for your personal contributions:

Ask your fund for a ‘Notice of intent to claim or vary a deduction for personal super contributions’ form (or download it from their website).
Fill it in with the amount you want to claim.
Send it to the fund and wait for their written acknowledgement.

You must receive this acknowledgement before you lodge your tax return, or before the end of the following financial year (whichever comes first).

Once acknowledged, those contributions are treated as concessional contributions

Step 7: Claim the deduction in your tax return

Finally:

Work with your accountant (or your own lodgement software) to claim the deduction in your individual tax return, not as a business expense in your profit and loss.
The deduction reduces your taxable income, while your contribution is taxed at 15% in the fund (within cap limits).

And that’s the full loop: you’ve paid super as a sole trader, properly documented it, and claimed the tax benefit.

What is the difference between concessional and non-concessional super contributions?

You’ll see these two terms everywhere, so let’s keep them simple:

Concessional contributions (before-tax)

Include employer SG, salary sacrifice and personal contributions you claim a deduction for.
Taxed at 15% in the fund (extra 15% may apply if your income is very high).
Count towards the $30,000 annual concessional cap (from 1 July 2024).

Non-concessional contributions (after-tax)

Contributions you don’t claim a deduction for, made from after-tax money.
Not taxed on the way into super (if within cap and eligibility).
Count towards the non-concessional cap (currently $120,000 per year, or up to $360,000 over three years using the bring-forward rule, subject to your total super balance).

How much super should a sole trader pay themselves?

There’s no one “right” answer, but here’s a practical way to think about it:

Use the SG rate as a benchmark
- Employers are required to contribute 12% of an employee’s ordinary time earnings from 1 July 2025.
- Many sole traders aim to put around 10–15% of their profit or drawings into super when cash flow allows.
Stress-test your cash flow
- Start smaller (e.g. 5–8%) and increase as your business stabilises.
- You can top up later using carry-forward concessional caps if you’re eligible.
Check the tax trade-off
- If you’re paying a marginal rate higher than 15%, concessional contributions can be very tax-efficient, up to the cap.

A good accountant will run the numbers with you so you’re not over-committing and putting your day-to-day business at risk.

What tax benefits, caps and ATO rules apply to sole trader super?

Here are the key rules most sole traders need to know:

Concessional cap: generally $30,000 per year from 1 July 2024 (for most people).
Carry-forward concessional cap: if your total super balance is under $500,000, you may be able to use unused cap space from the last five years in the current year.
Non-concessional cap: generally $120,000 per year, or up to three years’ worth at once (currently $360,000) using the bring-forward rule if you’re eligible.

Exceeding caps can mean:

Extra tax
Admin headaches
Potential adjustments to your return or fund.

That’s why tracking your contributions across all funds and getting advice before making large contributions is so important.

What are the government co-contribution and spouse contribution rules for super?

Two extra sweeteners often overlooked by sole traders:

Government co-contribution

If you:

Make after-tax contributions (and don’t claim a deduction), and
Your income is under certain thresholds,

the government may top up your super by up to $500 for a $1,000 contribution.

This can be attractive if you’re on a lower or fluctuating income.

Spouse contributions

If your spouse has a lower income, you may be able to:

Make contributions into their super, and
Receive a tax offset if certain conditions are met.

Do sole traders have to pay super for employees and contractors?

Even if you’re not required to pay super for yourself as a sole trader, you may need to pay it for others.

You generally must pay SG (at the current rate, 12% from 1 July 2025) if:

You have employees, or
You engage contractors who are paid mainly for their labour and meet the ATO’s criteria.

Key points:

Super must be paid to the correct fund by the due dates.
From 2026, SG is moving towards ‘payday super’, where contributions are paid at the same time as salary/wages, rather than quarterly.
If you don’t pay on time and in full, you may face the Super Guarantee Charge (SGC), which is more expensive and not tax-deductible.

This is an area where getting your bookkeeping and payroll set up properly saves you a lot of future pain.

FAQs on sole trader superannuation

Do sole traders have to pay super?

No. Sole traders and partners are not legally required to pay super for themselves, but they can make personal contributions. You are generally required to pay SG for eligible employees and certain contractors.

What happens if I don’t pay super for my employees?

If you have eligible employees or contractors and don’t pay SG correctly:

You may have to pay the Super Guarantee Charge (SGC), which includes:
- The SG shortfall
- Interest
- An administration fee
The SGC is not tax-deductible, and penalties can apply.

What if I’m a sole trader and also an employee for someone else?

Your employer still has to pay SG on your salary from that job. Any personal contributions you make as a sole trader are on top of that and all concessional contributions (employer and your deductible personal contributions) count towards the same annual concessional cap, so you need to track everything carefully.
