This will only happen if in some future year the IT dept notices something out of the ordinary and sends a scrutiny notice. It will then perhaps open earlier years.People in this thread are believing that once the ITR is processed then story is over and are celebrating the same....However, for income Upto Rs. 50 lakhs - The cases can be scrutinized within 3 years from the end of the assessment year. Above Rs. 50 lakhs - The time limit is 5 years.
So nothing to celebrate..Processing is just an intimation that prima facie there is no discrepancy or error in return...
For many normal tax payers that have repetitive income sources and similar trending returns, the processing closes the issue.
