If you do not receive your W-2, IRS.gov has remedies:
Call the IRS. Taxpayers who are unable to get a copy from their employer by the end of February may call the IRS at 1-800-829-1040 for a substitute W-2. The IRS will send a letter to the employer on taxpayers’ behalf. When they call, taxpayers need their:
Name, address, Social Security number and phone number.
Employer’s name, address and phone number.
Employment dates.
Estimate of wages and federal income tax withheld. Use a final pay stub for these amounts.
