Maximize Your Retirement Savings by Using Carry Forward Super Contributions Before the Deadline

June 12, 2026 - 12:36

You have roughly 10 days left to take advantage of a key superannuation rule that could significantly boost your retirement nest egg. The carry forward contribution rule allows eligible Australians to use unused concessional contribution caps from previous financial years, potentially adding tens of thousands of dollars to their super balance.

Under current rules, if your total super balance is below $500,000 at the end of the previous financial year, you can access unused cap amounts from up to five years earlier. This means someone who has not maxed out their annual $27,500 concessional cap in recent years could contribute far more than the standard limit in a single year.

Financial experts warn that failing to act before June 30 means losing access to the oldest unused amounts. The five-year rolling window resets each year, so any unused cap from 2019-20 will disappear after this financial year ends. For example, if you had $15,000 of unused cap from that year, you cannot carry it forward after July 1.

The strategy works best for those with irregular income, such as business owners or people who sold assets and want to reduce tax. Concessional contributions, including employer contributions and salary sacrifice, are taxed at just 15% inside super, compared to marginal tax rates that can reach 45%.

To use the rule, you must first check your carry forward available amount through your myGov account linked to the Australian Taxation Office. Then make the extra contribution before June 30 and claim it as a tax deduction. But be careful not to exceed the $500,000 balance threshold, or the unused cap is lost permanently.

While the deadline is tight, even a single year of catch-up contributions can compound over time. A $25,000 extra contribution today, growing at 7% annually, could become over $95,000 in 20 years. That is real money for retirement.
