I am getting "An application error has occurred while processing your request" when I try to submit my BAS.

Hello @JayDub,

Currently, we have an on-going issue where users, like you, are unable to submit your BAS with an error message saying An application error has occurred while processing your request.

Rest assured that we've already informed our engineering team about this and they're diligently working in all hand s to fix this as soon as possible.

In the meantime, you may want to consider manually submitting your BAS directly from the Australian Taxation Office Business Portal page. This way, you can avoid submitting your BAS with late fees or penalties.

In addition, I'd recommend contacting our Customer Care Support so you'll be added to the list of affected users. Once added, you'll receive all available updates about this investigation through your email. To do so:

1. 1. Log in to your QuickBooks Online account.
   2. Go to the Help menu at the upper right.
   3. In the Search bar, type Contact Us.
   4. Click the Contact Us option.
   5. Choose Callback.
       
      For support availability time, feel free to view this article: Get help with QuickBooks products and services.
    

Lastly, I've also included our GST and BAS Help Articles hub in case you need some easy steps for your future GST and BAS tasks.

We appreciate your patience as we're working on this, please let me know in the comment section down below if you have any other questions.
