I'm trying to lodge my BAS and its coming up with "An application error has occurred while processing your request. The BAS I'm submitting has previous months adjustments

Hi sarahandj, 

Are you trying to mark the BAS as lodged or electronically lodge via QuickBooks? 

If you are marking as lodged please try using an Incognito window or another browser to see if that works. 

If you are electronically lodging to the ATO please call us on 1800 046 038 and one of our support representatives will be able to investigate this for you.
