I have found that the product category does not carry over to the invoice and with out the category it doesn’t know the proper tax rate. So, even though the tax box is checked on the markup, without the category the tax is not calculated.
I have to copy my description and make a note of the totals, select the category (which deletes all the other information), paste the description back in and manual enter my costs and item numbers. Then it will calculate the tax.
This really needs to be fixed.
