Hot to change Woocommerce Tax Calculation

Hi! I need help with next issue – my woocommerce shop has products with prices includes taxes. I have configurated few tax zones for some countries, but i have next problem – Woocommerce can make subtotal price for product without taxes only for shop base country (in my case it’s United Kingdom). For example – if i set price for product 99 pounds, it will show 82.5 pounds price for product in checkout, and 16.5 pounds (20% of subtotal price). All is good, but if i will change country, for example Spain, i will get 82.5 pounds (basic product price) and 17.33 pounds of tax (21% of subtotal price for Spain). Total will be 99.83 pound.

I want to have total price the same for all countries, but subtotal price (without tax) must be dynamic. If i have 82.5 pounds (Subtotal) with 16.5 pounds VAT (20% for UK), i must have 81.81 pounds(Subtotal) and 17.19 pounds VAT (21% for Spain). In 2 cases total must be 99 pounds.

Will be glad to get help from you! Thank you!
