The data structure (file format) in which the AIR is to be prepared is given below: Data Structure (File format).
Once the file has been prepared as per the file format, it should be verified using the File Validation Utility (FVU) provided by Protean.
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.
