Caleb Burks on "Recalculate tax on woocommerce checkout page"

I have added some custom fields in the products with tax exempt feature enabled or disabled. If any product with enabled tax exempt is in the cart. I want to remove its tax from the checkout and re-calculate the tax. How can i update checkout on woocommerce page?

You can turn taxes off for a product using this setting: http://cld.wthms.co/1lSYp/5ZQQCuJO

If you need to code this customization though for some reason, have a look at what this plugin does in the code: https://wordpress.org/plugins/woocommerce-super-simple-tax-exemption/
