In the first instance you will need to go to the LodgeIT (http://www.lodgeit.net.au/) website and set up an account.
You will need to provide LodgeIT with information about your Fund, including its legal name, ABN, and tax file number, and contact information (name, address, phone number) of the signatory.
Once you are registered as a user of LodgeIT, you can create multiple user profiles, so you can use it to lodge tax returns for other entities you control and for your personal tax returns.
LodgeIT will then display your Fund details on a Client list.
And provide options for you to lodge Activity Statements, a Tax File Number Declaration, PAYG Summary or Self Managed Superannuation Fund Tax Return.
LodgeIT will store lodged forms for future reference, and allow you to store incomplete draft forms pending completion and lodgement.
