Wow,  I can't believe this problem has been reported for over 3 years and it still has not been fixed.   Telling us to manually add a subtotal is not a great workaround.  We should not have to do this.   The only way to fix this now is to set up a 0% tax level and mark and item taxable.  But again, that is just a workaround.  

Intuit - You need to fix this.  And why did you take away custom form styles?  That could have been a way to fix this too.
