Does Quickbooks Payments charge tax?

Hi strategiccontrol,

I can see how important it is to understand Merchant fees when using the payments feature in QuickBooks Online.  I'd be happy to confirm that there's no sales tax on processing fees.  For your reference you can review the Intuit Payments Merchant Agreement.

If there's anything else we can assist you with, please don't hesitate to reach back out.  Have a great day!
