Users are encountering the TDS return validation error T-FV-3175 when using the latest RPU 4.6 utility and CSI files. This error suggests an outdated FVU or CSI file, but users confirm they are using the latest versions. Solutions discussed include re-downloading the RPU and CSI files from the Income Tax website, as some users found their returns validated even with missing challans, particularly those paid via the Income Tax portal rather than OLTAS. If problems persist, raising a ticket with the IT department is recommended.
T-FV-3175 Either you are using old FVU version or old challan file (i.e. .csi file), please use the latest FVU version and challan file available at www.tin-nsdl.com and validate the file.
