Carry-Forward Super Contributions: How to Use Your Unused Cap (2026-27)

Updated 8 November 2026. Figures are for 2026-27 and come from the ATO pages listed under Sources, read on 8 November 2026.

The concessional contributions cap is not always use-it-or-lose-it. If your total super balance was less than $500,000 at 30 June of the previous financial year, you can use unused cap amounts from up to 5 earlier years and contribute more than the headline cap in a single year. This guide explains who qualifies, how the amounts are used, and how to work out your own number.

The headline cap for 2026-27

The ATO says the concessional contributions cap is $32,500 from 1 July 2026. It was $30,000 from 1 July 2024 to 30 June 2026, $27,500 from 1 July 2021 to 30 June 2024, and $25,000 from 1 July 2017 to 30 June 2021. (ATO, "Concessional contributions cap", page last updated 2 July 2026, read 8 November 2026.)

The ATO says that if you are eligible to claim a tax deduction for your personal super contributions, the amount allowed as a deduction is included in your concessional contributions cap, and that contributions count towards a cap in the year your super fund receives them. Employer contributions and salary sacrifice count towards the same cap, so your employer's contributions use up part of it before you add anything yourself. Our salary sacrifice guide covers that side.

The carry-forward rule

The ATO sets out these conditions:

If you still have excess concessional contributions after the unused amounts are applied, the ATO says you may need to pay extra tax (see "What happens if you go over" below).

Which years can you reach in 2026-27?

The 5 previous financial years for 2026-27 are 2021-22 to 2025-26. The ATO's general concessional caps for those years:

General concessional contributions cap by financial year (ATO, Contributions caps, Table 1.1).
Financial yearConcessional cap
2021-22$27,500
2022-23$27,500
2023-24$27,500
2024-25$30,000
2025-26$30,000

Source: ATO, "Contributions caps" (page last updated 11 September 2026, read 8 November 2026), and the ATO concessional cap page above.

The theoretical ceiling (our arithmetic, not an ATO figure): if you had made no concessional contributions at all in those five years, the unused amounts would add up to $27,500 + $27,500 + $27,500 + $30,000 + $30,000 = $142,500. Add the 2026-27 cap of $32,500 and the most you could contribute as concessional contributions in 2026-27 is $175,000. In practice, contributions made in earlier years, such as employer contributions, reduce the unused amounts.

A worked example (hypothetical numbers)

Say contributions were the following in each year, with nothing else going in. These amounts are made up for illustration and are not a Super Guarantee calculation.

Hypothetical concessional contributions and the unused cap each year.
YearCapConcessional contributions (hypothetical)Unused
2021-22$27,500$9,000$18,500
2022-23$27,500$9,500$18,000
2023-24$27,500$10,000$17,500
2024-25$30,000$10,500$19,500
2025-26$30,000$11,000$19,000

Unused total: $18,500 + $18,000 + $17,500 + $19,500 + $19,000 = $92,500.

In 2026-27 the cap is $32,500. Suppose $12,000 of employer contributions go in this year. That leaves $32,500 - $12,000 = $20,500 of this year's cap, plus the $92,500 of carry-forward, if your balance at 30 June 2026 was less than $500,000. So the most that could go in as a personal contribution you are allowed to claim as a deduction, without exceeding the cap, is $113,000. That is $20,500 + $92,500, our arithmetic from the made-up figures above.

If you contribute less than the full amount, the oldest unused amounts are used first. Here that is the 2021-22 amount of $18,500, which is also the first to expire: amounts not used by the end of 2026-27 expire.

Why people use it

These are our general examples of when someone might look at carry-forward, not ATO statements, and they say nothing about the tax result in any case:

Contributing more is not automatically a good idea. Super has its own rules about when you can access the money, so consider whether you will need it. The retirement simulator shows what extra contributions do to a projected balance.

What happens if you go over

If you still have excess concessional contributions (ECC) after unused cap amounts are applied, the ATO says the ECC are included in your assessable income and taxed at your marginal tax rate less a 15% tax offset. You can withdraw up to 85% of your ECC from your super fund. If you do not or cannot elect to release your ECC, the ATO says you could pay up to 94% in tax. From 1 July 2021, the ECC charge no longer applies. (ATO, "Concessional contributions cap", read 8 November 2026.)

Check your own number

  1. Find your total super balance at 30 June 2026. It must be less than $500,000.
  2. Check your carry-forward amounts in ATO online services (Super, Information, Carry forward concessional contributions).
  3. Subtract this year's employer contributions from the 2026-27 cap of $32,500.
  4. Use the Super Concessional Cap Tracker to see how much of this year's cap you have used. It does not include carry-forward amounts, so add those from step 2 yourself.
  5. See what extra contributions do to your retirement balance in the Retirement Savings Calculator.
