Hi there,
Your tax settings can be easily changed in QuickBooks Online so that the default selection is Exclusive of Tax. I'd be happy to let you know how.
To change this setting, follow the steps listed below:
1. Click the Gear icon
2. Click Account and Settings
3. Select Advanced
4. Click the small Pencil icon next to the Accounting section
5. Change the Default tax rate selection to Exclusive of Tax
6. Click Done
That's all there is to it. I hope this helps. Let me know if you've got questions.
Have a great day!
