Hi, I'm semi-retired and thinking about withdrawing $100k from my super to help my son with a first home deposit.
He would like to repay me plus 2 to 3 percent interest.
I'm wondering if I would have to pay tax on the small income from his interest payments.
Thank you.
The source of the interest is not relevant. From ATO
"If you're an Australian resident and you receive interest, you must declare it as income.
Interest income includes:
Investment income | Australian Taxation Office
Whether you pay tax on the interest depends on your total taxable income for the year.
