If you aren't seeing sales tax appear on your building or APS estimate, there are a few things you can check to ensure that it gets applied correctly. First, go to the Total Page of the estimate. 

At the top of this page, click on the Sales Tax button. This will open a pop-up window where you can choose how sale will be applied to the estimate. If you aren't seeing sales tax apply to every item, be sure to look into the the cost make up of the item. For instance, if you only apply sales tax to Materials, and the cost makeup of a particular item only comes from Labor and Equipment, then that particular item will not have sale tax applied to it.

Ensure that you have entered the appropriate percentage into the Sales Tax Rate section in the lower left. 

If you want to manually enter the sales tax dollar amount, select the Override Sales Tax Amount option. This will require you to calculate the amount of sales tax that should be applied to the estimate.
