Years ago I was told how to do it in QB. It works fine, but a lot of steps. I was hoping there was a easier way. My way causes a problem if you don't switch back to the original settings. My way you set a Capped in the item list with 0% sales tax rate. When creating an invoice you type in the info as normal, next line under item you select Capped. Go to next line in the item column select the county in which sales tax is to be charged. Manually calculate the sales tax and enter it.
In the "tax" box at the bottom of the invoice select Capped.
Please verify this with a QB Pro. but this also makes it so my sales tax report comes out correctly. Just a lot of steps and you have to remember to change info back or the next invoice will not be correct.
As of now, there isn't an automatic way to set up a sales tax cap in QuickBooks. You can set a sales tax cap by tracking it manually. However, this may cause some issues in your reports.
I understand how important the option of setting up sales tax cap automatically. I'll do take note with this and pass along the information to our product engineers. This way, they'll be able to know and work on with this.
