Tax informant procedure: contact designated investigation officers to be directed to the JDIT and furnish Annexure-A for reward consideration. A person with information about substantial tax evasion seeking reward must contact DGIT (Inv.)/PDIT (Inv.)/JDIT (Inv.); if the informant appears before DGIT (Inv.) or PDIT (Inv.), they will direct the informant to the relevant JDIT (Inv.) to furnish the information in Annexure-A for reward consideration.
