Not sure what you mean by "Do i need to post mark it ?"
You have to sign and date the Form 1040 on page 2 of the form.
Since you have to mail the tax return it would be in your best interest to pay for a tracking service from the US post office so that you know that the tax return was actually received by the IRS.
The postmark on the envelope from the US post office will be used by the IRS for the date it was mailed.
