title: Get the tax rate(s) from an order in WooCommerce 3
body: <p>I'm displaying my products in the cart without any taxes because I'm adding them afterwords to the subtotal sum in the cart. The problem is that I can't find a way to get the tax rate used for an order later on the <strong>My Orders</strong> page. So I'm looking for a way to get the tax rate used during the checkout for an order. The rate can be different depending on the country. </p>
  
  <p>What I have is: </p>
  
  <pre><code>global $order;
  
  $order-&gt;get_the_used_tax_rate_somehow();
  </code></pre>
