This is probably a very simple solution, that I'm just not seeing.  I purchase items for resale to my clients (as part of larger projects).  In several cases, I pay sales tax (California US) on the purchase of the items.  I then mark-up the items and sell them to my clients.  I need to be able to track the sales tax I PAID at the time of purchase and have it debit what I owe the local authority. 

In the Bill for the purchase, I don't see a way to add the sales tax.  I tried to make a new "account" but can't tie it to the tax payable liability, so looking for help here.  This is pretty standard stuff I would think.

Thanks
