How to Record and Report Non-Concessional Super Contributions in Your Books

Recording and reporting non-concessional super contributions in your books can feel like a juggling act, especially when you’re balancing business demands and the latest updates from the Australian Taxation Office (ATO). Getting it wrong can mean paying extra tax, missing out on valuable tax offsets, or even breaching your non-concessional cap—each a headache you’d rather avoid. This guide walks you through the process in plain language, helping you keep your records accurate, your retirement savings growing, and your stress levels in check.

Why Non-Concessional Contributions Need Extra Care

Non-concessional contributions—also known as after-tax super contributions—are a key part of building your retirement savings, but they come with rules that need careful attention. Because these contributions use money you’ve already paid tax on, they’re treated differently from concessional (before-tax) contributions. Understanding the difference, the caps, and the reporting requirements will help you avoid costly mistakes and make the most of your super.

What Counts as Non-Concessional Contributions?

Non-concessional contributions are personal contributions you make to your super fund from your after-tax pay. This includes money you transfer directly from your bank account, extra contributions you make for a spouse, and any excess concessional contributions that weren’t released from your fund and now count towards your non-concessional cap. Certain foreign super transfers and recontributions of benefits you’ve previously withdrawn (and didn’t claim a deduction for) also count as non-concessional.

Because this money has already been taxed, you can’t claim a deduction for it in your tax return. However, once it’s in your super account, it grows tax-free, helping to boost your retirement savings over time.

How Contribution Caps Work

For the 2025–26 financial year, the general non-concessional contributions cap is $120,000. This is the most you can contribute from your after-tax pay without facing extra tax. If you have more than one super fund, all your non-concessional contributions across all funds are added together and count towards this cap.

If your total super balance was less than $1.76 million at the end of the previous financial year, you may be able to use the bring-forward rule. This lets you contribute up to three years’ worth of non-concessional caps in a single year—potentially $360,000—if you’re eligible. Once you trigger the bring-forward rule, you’re locked into that cap amount for the next two or three years, even if the general cap increases in the meantime.

If your total super balance is $2 million or more at the end of the previous financial year, you generally can’t make any non-concessional contributions at all.

Risks of Getting It Wrong

Getting your non-concessional contributions wrong can lead to penalties, extra tax, and missed opportunities. Here are the main risks to watch out for:

• Breaching your cap: If you contribute more than your cap allows, the ATO will issue an excess determination. You’ll need to either withdraw the excess (plus 85% of any associated earnings) or pay extra tax on it at a rate of 47%.
• Misclassifying contributions: If you accidentally treat a non-concessional contribution as concessional and claim a tax deduction, you may face penalties and need to amend your tax return.
• Missing government rewards: If you’re eligible, the government co-contribution can add up to $500 to your super when you make after-tax contributions. Poor record-keeping or misclassification can mean you miss out on this benefit.

Step-by-Step Guide to Recording Non-Concessional Contributions

A clear, organised approach to recording non-concessional contributions will help you stay compliant and make tax time smoother.

Set Up Your Chart of Accounts

Start by creating dedicated accounts in your accounting system for after-tax super contributions. This might include:

• After-Tax Super Contributions (Asset): Tracks money moving from your bank to your super account.
• Owner or Member Equity – After Tax: Keeps personal injections separate from business costs.
• Super Liability Account: If your business withholds amounts from wages before forwarding them to the fund, set up a matching liability account to track these until they’re paid.

Record Personal Contributions

When you make a personal non-concessional contribution, record it with a simple journal entry:

• Debit: After-Tax Super Contributions (Asset)
• Credit: Bank Account (Asset) or Owner’s Drawings

This shows the movement of money from your personal resources to your super account. If you use direct debit, include “non-concessional” and the member’s name in the narration for easy reconciliation.

Track Employee Extras and Salary Sacrifice

Employees may make extra contributions through salary sacrifice (using before-tax pay) or as after-tax deductions from their take-home pay. Salary sacrifice amounts are concessional and should be kept separate from non-concessional entries.

If an employee makes an extra non-concessional contribution from their after-tax pay:

• Withhold the amount as a post-tax deduction in payroll.
• Post it to the After-Tax Super Contributions liability account.
• Remit the amount to the super fund by the due date.

Clear labelling helps avoid confusion—especially when staff ask whether a particular contribution can be claimed as a tax deduction.

Keep Source Documents Handy

Hold on to all relevant paperwork, including fund receipts, bank statements, deduction notices, employee consent forms, and payroll reports. The ATO requires you to keep these records for at least five financial years.

Staying Within Your Caps and Reporting on Time

Good record-keeping is just the start. You also need to monitor your caps and meet reporting deadlines.

Watch Your Total Super Balance

Your ability to make non-concessional contributions depends on your total super balance at 30 June each year. Check all your super accounts (including any you might have forgotten) and add up the balances to see where you stand. If you’re close to the $2 million cap, you may no longer be eligible to make non-concessional contributions.

Use the Bring-Forward Rule Wisely

If you’re eligible, the bring-forward rule lets you contribute more in a single year, but you’ll need to track your remaining cap over the next two or three years. Spreadsheets or dedicated apps can help you keep track.

Reporting to the ATO and Your Super Fund

Super funds report contributions to the ATO, but it’s up to you to confirm that everything’s coded correctly. Make sure any notice of intent to claim a deduction for concessional contributions is lodged before you submit your tax return. Double-check that your assessable income, Medicare levy, and any income tax withheld match your payroll records.

Common Roadblocks and Practical Fixes

Even with the best systems, mistakes can happen. Here are some common issues and how to fix them:

• Mixing up pre-tax and after-tax money: If you accidentally code a salary sacrifice as a non-concessional contribution, reverse the entry and re-code it correctly. Clear payroll item names help prevent this.
• Overlooking the government co-contribution: Make sure eligible employees’ after-tax contributions are coded correctly and reach the fund before 30 June.
• Forgetting to reconcile the liability account: Regularly check that your books match your fund statements. If you find old entries, match them to receipts or reverse duplicates.
• Ignoring the effect of assessable income: If a bonus or windfall pushes your assessable income over the threshold, you might lose eligibility for the co-contribution or face a higher tax rate. Plan ahead and adjust your strategy if needed.

Best Practice Checklist

Follow these steps to keep your non-concessional contributions on track:

• Label every contribution as concessional or non-concessional before posting.
• Track your caps in real time—use software or a simple spreadsheet.
• Reconcile your super clearing house report against your ledger each month.
• Keep digital or paper evidence for at least five years.
• Review your total super balance every July and plan for the new cap.
• Educate your team on the difference between pre- and after-tax contributions.

Conclusion

Recording and reporting non-concessional super contributions doesn’t have to be overwhelming. With clear accounts, accurate labelling, and regular checks, you can protect your retirement savings, avoid extra tax, and make the most of your super. If you’re unsure about your eligibility, limits, or the right mix of contributions, seek advice early. Ready to take control of your super strategy? Start by reviewing your recent entries—then tackle any gaps before the next deadline. Your future self will thank you.
