If you're under 75 and have less than $1.7 million in super, you may be able to bring forward up to three years of non-concessional (after-tax) contributions. This means you can contribute up to $330,000 over three years, rather than $110,000 each year.
For example, if you make $150,000 in non-concessional contributions in the 2022-23 financial year, you’ll go over the $110,000 cap by $40,000. The bring-forward rule allows you to make this contribution and contribute another $180,000 over the following two years without breaching the cap.
Visit the ATO website for more information about contribution limits and the bring forward rule.
