IT Challan correction

If you've mistakenly entered the wrong assessment year when paying your IT challan, there are a few ways to rectify it. You can file an Income Tax Return (ITR) for the incorrect year to claim a refund and then pay again for the correct year. Alternatively, you may be able to request a correction through your Assessing Officer (AO). Some users suggest that logging into TRACES and selecting the 'challan correction' option can resolve the issue within a couple of days, though this may apply more to TDS challans.
