I recently completed my BAS for the June quater(April to June). The PAYG component of the bas lodgement is automatically completed for the month of June using the payroll submissions i made during the month so i didn't bother to check if it was correct. After completeing the BAS i had cause to go back and check the information I supplied. I noticed that the PAYG component was incorrect and only one of the two Payroll submissions had recorded the correct amounts. I now owe the tax office for the non reported payroll. How do I fix this?
