The Australian Taxation Office has started issuing excess concessional contributions (ECC) determinations for the 2017–2018 financial year. Superannuation fund members will receive these ECC determinations if they have made super contributions above the concessional cap amount for 2017–2018.
“Concessional” contributions are taxed at the reduced rate of 15% in your super fund, but there’s a limit to how much you can contribute at this rate ($25,000 for 2017–2018).
Fund members may also receive an amended income tax return assessment together with the ECC determination, and may need to pay additional amounts to the ATO. This is because any super contributions you make over the concessional cap need to be included in your assessable income for the financial year, and an interest charge applies.
Salary sacrifice arrangements need to be carefully reviewed each year.
