@arpanghosh1990 Anything you mail will have a postmark that is put there by the post office. I think you mean ---should I use a mailing service to track it? Yes, you should so that you know the IRS received it. It takes months for the IRS to process a mailed return. Unless you use a service that will track it and tell you the IRS received your return you will be waiting and wondering for months if they even received it.
Use certified mail from the post office and you will get a receipt back that shows the return was received by the IRS.
