Intel mails your W2 to the mailing address that they have on record for you as of the end of the previous year. It will be mailed by January 31st every year. If you have not received your W2 by the middle of February, you can call the Get HR Help 800 number (1-800-238-0486) to request a copy. If you have received your W2 and have questions, you can also request a W2 Breakdown Letter which details what was included in each box on your W2.
You will get through to a Get HR Help rep by selecting either the payroll option or option zero. Remember to use the voicemail/call back option if hold times are long.
