• Attempt to get your Form W-2, Form W-2c, or Form 1099-R (original or corrected) from your employer or payer before contacting the IRS or
filing Form 4852.

employment. You must also provide your employer’s or payer’s name, address (including ZIP code), and phone number. The IRS will contact
your employer or payer and request the missing form. The IRS will also send you a Form 4852. If you don’t receive the missing form in
