Self-assessment tax not showing in AIS even after 10 days

Thank you sir.

 I have placed a grievance to AO through the portal Today.

 Whether I should send onemore to CPC-ITR also?

No.  Wait till its reply.         

Self-assessment tax paid via Challan 280 typically takes 3 to 5 working days to reflect in AIS and Form 26AS. Two checks to run if it has not shown up after 10 days:

1. Verify on OLTAS (tin.tin.nsdl.com/oltas) that the challan has been processed and shows status Booked. If OLTAS shows it as booked, the credit is confirmed on the government side and AIS will eventually update.

2. Cross-check the CIN (Challan Identification Number) and your PAN in the challan receipt. A PAN mismatch at the time of payment causes the credit to be applied to a different account and AIS will never reflect it under your PAN.

If OLTAS shows Booked but AIS still does not update after 15 days, raise a grievance on the income tax portal under My Account > Grievance/Complaints with the CIN and bank details.

Important for ITR filing: you do not need to wait for AIS to update. You can file your ITR right now by entering the challan details manually in Schedule IT (Taxes Paid) using the CIN, BSR code, and payment date. AIS will show the credit later and the system will auto-reconcile.
