Comment 21 for bug 1108801

Also, regarding the Taxes on the invoice, why for each separate tax that I add, it shows a Base amount original amount of the invoice added to that sum each time I apply another tax.

Example:
My total invoice is for $600.00 and I apply a state tax at .06875 or 6.875%, base says $600.00, then I apply another separate City Tax at .0050 or .05% and now the base says $1200.00 and then I add my 3rd Tax a County Tax of .00250 or .0250% and the base now says $1800.00. This gets printed on the invoice and I just don't understand why can someone please help me or explain this to me?

Thanks
