TDS Return acknowledgement number lost

Ask the tin fc where you filed the TDS return. They would have a copy of the PRN.

If the return is filed through efiling site then you can download it from there.

By both ways you can't retrieve the PRN just prepare the Q4 and submit it in the tin fc where you submit Q3. There is a way to find the previous PRN.

While preparing select 'No' for the question whether previous return filed?

Sir client have no idea from which Tin FC , return for Q3 was filed as this was filed by previous employee who can't be traced..

In this case you just file q4/returns as said in previous reply. You will receive intimations letter from TDSCPC. It will have a masked PRN which has the first 4 and last 4 digits of PRN. There is a way to retrieve the number from that.

Thank you sir ...
