Very Simple Code Snippet for Creating Taxonomy for Custom Post Type
Register Custom Post Type
function Knowledge_base_init() {
$labels = array(

'not_found_in_trash' => __( 'No Knowledge bases found in Trash.', 'your-plugin-textdomain' )
);
$args = array(
'labels' => $labels,
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'query_var' => true,

}
add_action( 'init', 'create_knowledge_base_taxonomies', 0 );
function create_knowledge_base_taxonomies() {
// Add Tips taxonomies
$labels = array(

$args = array(
'hierarchical' => true,
'labels' => $labels,
'show_ui' => true,
'show_admin_column' => true,
'query_var' => true,
'rewrite' => array( 'slug' => 'tips' ),
);
register_taxonomy( 'tips', array( 'knowledge-base' ), $args );
}
That help you for creating taxonomy.
