Why search for correct
PIO? You can file
RTI application with any
PIO of Income Tax Dept at Mumbai or Chhenai and he is bound to redirect the application to the appropriate
PIO depending upon matter of
RTI application, within 5 days of receipt by him. Just send the details with a Rs.10/- ipo fvg Accounts Officer, Income Tax Dept, Govt of India. This should suffice.
