The TaxCloud integration allows you to correctly calculate the sales tax for every address in the United States and keeps track of which products are exempt from sales tax and in which states each exemption applies. TaxCloud calculates sales tax in real-time for every state, city, and special jurisdiction in the United States.

How it works
Salestax is calculated in Odoo based on fiscal positions (see Adapt taxes to my customer status or localization). A Fiscal Position for the United States is created when installing TaxCloud. Everything works out-of-the-box.
You can configure Odoo to automtically detect which Customers should use this fiscal position. Go toto open and edit the record.
Now, this fiscal position is automatically set on any sales order, web order, or invoice when the customer country is United States. This triggers the automated tax computation.
Add your product(s). You have two options to get Sales Tax on the Order. You can confirm it, or you can save it and from the Action Menu choose Update Taxes with TaxCloud.
Coupons & Promotions
If you use the Coupon or Promotion Programs, the integration with Taxcloud might seem a bit odd.
The problem lies with the fact that Taxcloud does not accept lines with negative amounts as part of the tax computation. This means that the amount of the lines added by the promotion program must be deduced from the total of the lines it impacts. This means, amongst other complications, that orders that use coupons or promotions with a Taxcloud fiscal position must be invoiced completely - you cannot create invoices for partial deliveries, etc.
Another specific oddity is possible in the UI: imagine that you sell a product from the Taxcloud category  Computers and that you have a promotion program in place that provides a 50% discount on this product. If the tax rate for this particular product is 7%, the tax rate that will be computed from the Taxcloud integration will display 3.5%. This happens because the discount is included in the price that is sent to Taxcloud, but in Odoo this discount is in another line entirely. At the end of the day, your tax computation will be correct (since a 3.5% tax on the full price is the equivalent of a 7% tax on half the price), but this might be surprising from a user point of view.
