I was told from my manager that I should have a w2 form send to me but I believe I accidentally deleted it from my email. How can I get it resend to me?
BTW, a W-2 would not be sent by e-mail as it's not secure. It may be available on a secure website IF you opted out of receiving a paper W-2 in the mail. If you didn't opt out, they must mail it to your last know address on file.
If you are gong to fill it out, it isn't a W-2. A W-2 is a report of earnings for last year. Did you mean a W-4, which is the form you fill out when you are hired (and change when you need to) to give information so payroll can withhold taxes properly?
Search your email. Some keep them on their systems forever and even deleted emails will show up in a search. Other than that, if the company has a website that your pick up your paystubs from, the form may be there.
