Surrender of st2 afetr centralization

Hi friends,

Our company has two offices - One in Mumbai & the other in Hyderabad, we were holding two Service Tax Registrations and respectively returns were being filed.

Now during this month we opted for Centralized Registration and we got Mumbai registered as our Centralized office for Service tax and received the fresh ST2 effecting the Centralized Registration,

Now my question is whether we are required to surrender the Service Tax registration of Hyderabad or does it stand automatically cancelled ... We have mentioned and registered the Hyderabad premises while obtaining Centralized registration - So are we still required to surrender the Individual Hyderabad registration by doing it online ...

Thanks for your views,

Regards,

Nirupa
