Thank you for reply
Yha we want tax id for taxfiling for our child.
He don't have any SSN & we don't know how to get SSN or tax id
He is not going to any daycare.tax id is needed to just to include him while filing the tax
Can u help us to solve these??

You can fill out Form W-7 and submit it to the IRS. I believe your need meets one of the exceptions that allows you to get an ITIN without filing a tax return.

You can get the form and instructions at Internal Revenue Service (http://www.irs.gov).
