Can I find my w2 form online from my past employer

There seems to be a misconception going around that all W2s are available online. That is certainly NOT the case. Its up to each individual company whether to make their W2s available. Also each company can choose HOW to make them available. Some companies may use w2express.com others may do it themselves, others may use a different service.

The bottomline here is that if your company makes them available the company needs to supply you with the information needed to get at it. So you need to ask a HR or Payroll person at your company about this.
