The overall process for acquiring annual SMSF return is long, organized and specific. The best thing you can do is to hire a super fund agent taking care because of his knowledge of the procedures and rules, and his vast experience. However, hiring an agent is needed when the audit has not been done otherwise you can do that yourself, meaning you will need to gather all the information and documents and deliver them to the agent yourself by the time frame he has given to you.
If you are managing the fund yourself, without the help of an agent, then you need to complete dozens of documentation, file financial reports and tax accounting and send the to the ATO commission before the last date for lodging. Afterwords, the ATO will scan and review all the documents you have send and in a situation that is something missing or not done as it should you will need to fix them. You should know that there are certain rules and obligations for super lodgement and if not done correctly there are special penalties that you will need to pay if you do not do the process as the guidelines say.
In the end, if you are not specialized in accounting and financial dealings, the best thing to do is to hire a professional that will do the job for you. You can be certain that your SMSF will be handled in the right and proper manner and you will be freed from that burden.
