Going strickly by the law there are no such provisions for reversal. This is the loophole in the law. There are high chances of department denying such reversal during departmental audit or scrutiny. Moreover, I don't think the provisions of income tax act can be used to interpret the provisions of service tax.
However, you may make such reversal if there is renegotiation of invoice or if you recieve a debit note from service reciever. The service tax law is silent about bad debts
