How can I get old W2 form from-my employer can provide it.?
You must first request it from the company that employed you in 2001, even if you know that they will not be able to provide it. After you have made a request to them, if they still have not provided it, you then “call the IRS at 800–829–1040 for assistance. You must provide your name, address (including zip code), phone number, Social Security Number, dates of employment, your employer/payer’s name, address (including zip code), and phone number. The IRS will contact the employer/payer for you and request the missing form. IRS will also send you a Form 4852 (PDF), Substitute for Form W-2 or Form 1099-R.” If you still have not received the W-2 by the time that the taxes must be filed, then you may file the taxes using the Form 4852 without the W-2.
