Superannuation for Self-Employed Tradies: What Actually Happens to Your Super on an ABN

As an apprentice, super turned up in your account without you thinking about it — your employer had to pay it. The day you go out on your own ABN, that stops. Nobody is legally required to pay super into your account, including you. It’s entirely optional, which is exactly why so many self-employed tradies end up with next to nothing in super by the time they’re 50.

The short version (TL;DR)

• If you’re a sole trader or running your own ABN, no one is required to pay super for you — not even yourself.
• You can make voluntary personal contributions and claim them as a tax deduction, which is the main upside of bothering.
• The concessional (before-tax) contributions cap for 2026–27 is $32,500; the non-concessional (after-tax) cap is $130,000.
• Unused concessional cap from previous years can sometimes be “carried forward” if your total super balance is under $500,000 — useful after a lean year followed by a good one.
• If you employ yourself through a company structure and pay yourself a wage, that changes things — company directors paying themselves wages generally do need to pay super guarantee on that wage.
• Skipping super entirely isn’t illegal for a sole trader — but it is how a lot of tradies end up relying entirely on the age pension at 67.

Why this actually matters for tradies specifically

Trade work is physically demanding, and a lot of tradies plan (whether they say it out loud or not) on stepping back from the tools earlier than a desk job would require. That makes super more important for tradies, not less — you’re relying on it to fund a longer retirement from work you may not be able to keep doing into your late 60s. Yet self-employed tradies are one of the groups least likely to have meaningful super, precisely because no one’s forcing the issue the way an employer would.

Sole trader vs. company: it changes your super situation

• Sole trader / ABN, no company structure: You’re not required to pay yourself super. Any super you have comes entirely from voluntary contributions you choose to make.
• Running through a company and paying yourself a wage: If you’re a director being paid a salary or wages by your own company, super guarantee obligations generally apply to that wage, the same as for any other employee — worth checking with your accountant, since getting this wrong is a common trap for tradies who’ve just set up a company.
• Mix of both (ABN work plus some subcontracted PAYG work): Any part of your income that’s genuinely an employment relationship (rather than a true contractor arrangement) may still attract compulsory super from that specific payer — this one’s genuinely worth a conversation with your accountant if your setup is mixed.

How much should you actually put in?

There’s no single right number, but a few practical anchors:

• Concessional (pre-tax) contributions cap, 2026–27: $32,500. This includes anything an employer pays plus your own deductible personal contributions. As a sole trader with no employer super, this cap is essentially all yours to use.
• Non-concessional (after-tax) cap, 2026–27: $130,000. Relevant if you’ve had a genuinely good year and want to put a lump sum in without claiming a tax deduction on it.
• Carry-forward provision: if your total super balance is under $500,000, you may be able to use unused concessional cap space from the past five years — useful if you had a couple of lean years and then a strong one and want to catch up.

The tax deduction angle (the actual reason to bother)

Personal super contributions are deductible against your taxable income, provided you notify your super fund of your intention to claim a deduction before you lodge your tax return (and before certain other events, like starting a pension). For a lot of self-employed tradies, this is the practical reason super contributions are worth making even without an employer forcing it — it’s one of the few genuinely legitimate ways to reduce taxable income while building something that’s actually yours, rather than just spending it.

What happens if you skip it entirely

Nothing happens today. That’s exactly the trap — there’s no penalty, no letter, no consequence in the short term. The cost shows up decades later: relying solely on the Age Pension, working past the point your body can handle it, or needing to sell down other assets. None of that is a lecture — it’s just the maths of what “optional” actually means over 20–30 years.

Frequently asked questions

Do I have to pay myself super as a sole trader?
No. It’s entirely voluntary. There’s no legal requirement for a sole trader to make super contributions to themselves.

What if I run my trade business through a company?
If you’re a company director paying yourself a wage, superannuation guarantee generally applies to that wage the same as for any other employee — this is different from the sole trader situation, so it’s worth confirming your exact setup with an accountant.

Can I catch up on missed years?
Potentially, via the carry-forward concessional contributions provision, if your total super balance is under $500,000. This lets you use unused cap space from the previous five financial years.

Is putting money into super actually worth it if I might need cash for tools or a slow month?
That’s a genuine trade-off — money in super is generally locked away until retirement (with very limited exceptions), so it shouldn’t come at the cost of your emergency cash buffer for slow periods. It’s worth thinking of super as what’s left over after your business cash flow is solid, not instead of it.
