Superannuation is one of the few genuinely concessional environments left in the Australian tax system, and the caps exist to limit how fast you can move money into it. Understanding which cap applies to which contribution — and what flexibility the carry-forward and bring-forward rules give you — is what separates effective super planning from an unexpected assessment.
What is the difference between concessional and non-concessional contributions?
Concessional contributions come from money that has not yet been taxed in your hands. They include employer super guarantee payments, salary sacrifice arrangements, and personal contributions you claim as a tax deduction. They are taxed at 15 per cent inside the fund, which is why they appeal to anyone on a marginal rate above that. Non-concessional contributions come from after-tax money — savings, an inheritance, proceeds from selling an asset. They are not deductible and are not taxed on entry, because the tax has already been paid.
How much can I contribute each year?
Each type has its own annual cap, and both are indexed periodically, so check the current figures for the financial year you are planning rather than relying on last year's number. What matters more than the headline amount is what counts towards it. Your concessional cap is consumed first by employer contributions, which many people forget when calculating how much salary sacrifice they can add. Non-concessional capacity also depends on your total superannuation balance — above a certain balance, the non-concessional cap reduces to nil regardless of your income.
What is the carry-forward rule and who benefits from it?
If your total super balance was under the relevant limit at the end of the previous financial year, you can use unused concessional cap from up to five prior years. This is the most useful and most underused provision in the system. It suits people with uneven income: a business owner having an exceptional year, someone who has sold an asset and faces a capital gain, a parent returning to work after time out of the workforce, or anyone who has spent years with only compulsory super going in. Unused amounts expire after five years on a rolling basis, so there is a use-it-or-lose-it element worth tracking.
What is the bring-forward rule?
The bring-forward rule works on the non-concessional side. Eligible people under the relevant age can contribute up to three years' worth of non-concessional cap in one year by drawing on future years' entitlements. It is commonly used when a lump sum arrives — a property sale, an inheritance, a business exit. Two cautions apply. Eligibility depends on your age and your total super balance at 30 June of the previous year, and the arrangement locks in once triggered, so a contribution made without checking can accidentally start the clock and restrict the following two years.
What happens if I exceed a cap?
Excess concessional contributions are included in your assessable income and taxed at your marginal rate, with an offset for the 15 per cent already paid by the fund, plus an interest charge. You can elect to release up to 85 per cent of the excess from super to help pay the resulting bill. Excess non-concessional contributions are treated more harshly: you either release them along with an amount of associated earnings that gets taxed, or leave them in the fund where they are taxed at the top marginal rate. The ATO issues a determination and you have a limited window to respond, so opening the letter promptly genuinely matters.
How do I claim a deduction for a personal contribution?
Making the contribution is only half of it. To claim a deduction you must give your fund a valid notice of intent to claim, and receive the fund's acknowledgement, before you lodge your return or before you roll the money out or start a pension. The notice cannot be varied upwards later. Every year some taxpayers make a perfectly valid contribution and lose the deduction purely on this procedural step — it is worth doing immediately rather than at return time.
How does timing affect a contribution?
A contribution counts in the financial year the fund receives it, not the year you send it. Payments made through a clearing house near the end of June regularly land in July, pushing a deduction into the following year and potentially wasting cap in the current one. If you are contributing to use carry-forward capacity or to offset a gain in a particular year, allow real time for the money to arrive — the last week of June is not the moment to be testing your clearing house's processing speed.
