Investment income needs to be included when conducting tax returns. This includes any income acquired through interest, dividends, rent, managed funds distributions, and capital gains. The income yielded from investments is taxed at a marginal tax rate.

Individuals are able to claim deductions for the cost of buying, managing, and selling an investment. However, the Australian Tax Office (ATO) provides rules about what an or cannot be claimed as a tax deduction.

The MoneySmart website has a simple and easy-to-use tax calculator that may give an indication as to what the annual tax will be. However, it is recommended that if an individual has a diverse portfolio that yields income from multiple sources, then should consult an accountant or advisor that can lead them through the process as it can become quite complex.

In order to minimise taxation on investment income, individuals should consider tax-effective investments that provide concessional taxation. These include superannuation and insurance bonds.
