From www.bantacs.com.au: Selling an investment property often results in significant capital gains, which can incur high tax liabilities; therefore, strategic planning around superannuation contributions is essential to mitigate these taxes.

Factors like age and unused contribution caps influence how much can be contributed to superannuation tax-deductibly, with different rules applying once a person turns 67 or 75 years old.

Understanding concessional and non-concessional contributions, as well as work test requirements, is crucial for optimizing tax benefits from property sales and ensuring effective retirement planning.
