No need to worry!
You can back date your GST registration up to 4 years dependent on the start date of your ABN registration.
You will need to lodge the BAS or annual GST statements for this backdated period. You will also need to pay GST on taxable supplies made.
It is best to seek advice from an accountant prior to backdating your GST as there may be other considerations to take into account.
