Tax not calculated when draft order created over admin REST API

[AlexPylypko]

Hi!

Could you please help to understand, why when I use Admin Rest API  endpoint admin/api/2021-10/draft_orders.json with POST request and provide all correct 

shipping_address properties in draft_order Tax value not calculated at all. The response is 200, but Tax is empty.

Also, I saw that when I go to the dashboard and open that draft order State section in the Shipping address not selected. Once update manually Tax starts showing properly. 

Thanks in advance
