If a refund cheque is dispatched by tax-dept., it would show that status and give a POD / AWB / Tracking no. of EMS Speed Post; and its detailed movement (incl. the local post-office)
If your mobile-no. is registered with the Income Tax dept. (and you can also register your mobile no. by calling 1800 425 2229), then they say that they would send an intimation whenever the refund is processed.
For refund cheques:
Refund cheque is sent through EMS Speed Post.
The address to which the refund is sent is as per what is mentioned while filing of ITR – For companies, usually this address is the company-regd.-addr. or PAN-address (For individual, this is usually the PAN-address)
To get refunds to a different address, first you need to change the PAN-address / company-regd.-addr. (as required), and after 1-week, call 1800 425 2229, for reprocessing the refund.
PS: The post-office said that they need company-stamp while receiving the courier of the cheque (not sure about this)
If the cheque is not received at the address, a not-delivered-slip is given. The post-office nearby keeps the packet for 4 to 5 days, and you can collect personally by taking the not-delivered-slip and your co. stamp (preferably between 9.30 and 11 am, and sometimes till 12 pm, separate counter handles these cases)
