If the data isn’t sent from the form, you can dump out the post value before your code and see what’s the actual key is. (maybe there’s a typo in your field key)
echo '<pre>';
print_r($_POST['acf']);
echo '</pre>';
Another reason might be, the form is sending the value as a string, but the wp functions requires a pure integer. See last example in the doc, https://codex.wordpress.org/Function_Reference/wp_set_post_terms
So, your code might even need to cast the value with intval
first.
'custom_tax_tag => array( intval($_POST['acf']['field_5a903d3132d04']) )
Cheers
