Straight out of the documentation

There are two events that get fired show.bs.tab & shown.bs.tab as their name implies one gets fired before the new content is shown, the other one right after.

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
  //e.target -> activated tab
  //e.relatedTarget -> previous tab
});
