Tried lodge BAS online unable 'as one or more obligations in my settings don't match what the ATO has on record for you. How do I find out what these obligations are?

Hi Tkbukka, 

The best way to check your obligations are by logging into your ATO portal. 

Please make sure your obligation according to ATO's registration is matching with the tax setting in QBO. 

Please let us know if you require additional assistance on this. Thank you
