Unfortunately none of this information is helpful.  I know how to set up a quickbooks file.  The customer is set up as taxable.  The Products are set up as taxable.  The system has decided not to charge sales tax on the mark up.  (The mark up is being calculated based on marking a billable expense on a bill and adding it to invoice.)  Nowhere is there a place I can select if mark up is taxable or not but why wouldn't it be attached to the item that is marked up (for example I have the product marked as taxable so the markup should be taxable as well).  On the invoices it doesn't even show the mark up it show just a total for the item.  Every place possible the tax box is checked yet it is not charging tax.

Also you might want to check when you give information out about how to contact your help line.  Step 1 doesn't even make sense.  Maybe try to change your copy and paste answer to say when you're logged into your account go to the top and click on HELP. Then at the bottom click on Contact Us.  Then you pick a topic and put in your question.   Then I can sit and wait to talk to someone that will then take my information again and send it to someone else because the front line people will not know how to fix my problem. 

How can I send an email to someone so I can submit several screen shots of my issue and it can go directly to a technical person and I don't have to explain it a dozen different times?
