Address of trust circle and charity commissioner in thane

Hello,

I want to file Trust returns and also file its account with Charity Commissioner. The issue is that the Trust has its registration in Thane(near Mumbai) with its Regn no. with the Charity Commissioner being E-**** (Thane). Where can I find the address of the Income Tax Office where I can file its return and where can I find the Charity Commissioner for the same?
