The ITR-V (Income Tax Return Verification) is an acknowledgement of your filed return, summarizing the basic details, such as your total income, deductions, and taxes paid. In contrast, the ITR form itself is the document where you provide all the details regarding your income, deductions, and personal information. If you choose to verify your return manually (instead of e-verification), you must physically sign the ITR-V and send it to the Centralized Processing Center (CPC) in Bengaluru within 30 days of filing the return.
