The data structure (file format) in which the AIR is to be prepared is given below: Data Structure (File format).
Prepare AIR in accordance with the file format in clean text ASCII format. AIR can be prepared using in-house software or any other third party software or NSDL Return Preparation Utility for Annual Information Return (AIR RPU).
Once the file has been prepared as per the file format, it should be verified using the File Validation Utility (FVU) provided by NSDL.
In case the file has any error, the FVU will give a report of the errors. Rectify the errors and verify the file again through the FVU. Repeat this step until an error free file is obtained.
The upload file generated by the FVU on successful validation should be copied on a CD/floppy. This CD/floppy alongwith a duly filled and signed print out of Part A of Form 61A should be submitted to any TIN-FC. Part A of Form 61A.
