Dear Jyotsna Shoknwar,
Employers are registered with the Local Commercial Tax Office and PT Officer (now VAT/SGST office). Most probably, your office is not registered with the Prof. Tax Office and hence not remitted, which is a punishable offense. The city of Ahmedabad, being a City Corporation, has the PT Officer at the Corporation office as the concerned officer. You may contact to ascertain what to do and how to do.
