I recently was working on a site trying to use custom post types and get tags to work. Getting tags to display using the_tags(); worked out just fine, but clicking the tag resulted in a 404 page. Here was the solution. I simply had to add this to my functions.php file.

add_filter('pre_get_posts', 'query_post_type');
function query_post_type($query) {
  if(is_category() || is_tag()) {
    $post_type = get_query_var('post_type');
	if($post_type)
	    $post_type = $post_type;
	else
	    $post_type = array('post','YOUR POST TYPE'); // replace cpt to your custom post type
    $query->set('post_type',$post_type);
	return $query;
    }
}

UPDATE

you need to add ‘nav_menu_item’ to the post type array or else navigation menus will disappear if you’re using wp_nav_menu to call your menus. The final code should look like…

add_filter('pre_get_posts', 'query_post_type');
function query_post_type($query) {
  if(is_category() || is_tag()) {
    $post_type = get_query_var('post_type');
	if($post_type)
	    $post_type = $post_type;
	else
	    $post_type = array('nav_menu_item', 'post','YOUR POST TYPE'); // replace cpt to your custom post type
    $query->set('post_type',$post_type);
	return $query;
    }
}
