How to get the current taxonomy term ID (not the slug) in WordPress?

Question

Nevermind! I found it :)

get_queried_object()->term_id;

Simple and easy!

get_queried_object_id()

Here's the whole code snippet needed:

$queried_object = get_queried_object();
$term_id = $queried_object->term_id;

Use following code

This will print your current taxonomy name and description(optional)

<?php 
   $tax = $wp_query->get_queried_object();
   echo ''. $tax->name . '';
   echo "<br>";
   echo ''. $tax->description .''; 
?>
