Some of the benefits of a self-managed super fund are:Flexibility. You have the flexibility to make decisions according to fluctuations in the market — and timing is critical when it comes to investing. Investing in stocks in Australia gives you greater control over your investments, so you can track their performance and adjust your investments accordingly.Diversification. You have the freedom to choose from a range of investments, industries and asset classes. From stocks in Australian securities to investing in cryptocurrencies, it can be a good idea to diversify your retirement portfolio to help reduce the risks associated with individual stocks. Be sure to do your research before deciding which asset types are right for you.Liquidity. A self-managed super fund lets you exit a stock at a time that suits you. Plus, most shares can be sold quickly.Assistance. You may have control over your super and be responsible for its financial and legal obligations, but that doesn’t mean you can’t seek professional advice. Consider speaking to an independent financial advisor to make the most of your SMSF.Tax credit. Because it is a retirement fund, your SMSF will only pay a flat 15% tax rate. Income from shares generally comes with a 30% tax credit, so you can claim back the difference.Tax savings. Super funds generally do not pay tax on all capital gains. That means once you have held an investment for over one year, only two-thirds of the gain is taxable. Over time, this could help you significantly increase your investment gains and help build your overall wealth.
