My company (> 5K employees globally) for which I've worked for 3+ years, announced that they were going to be verifying that every employee's health care dependent information was correct, as they don't want to be paying health claims on ineligible dependents. Fair enough. I expected to get a letter saying "we show these dependents on your health plan, please verify they still meet the following requirements, sign and return". Instead, they are requiring that I provide copies (to a third-party auditing firm) of my marriage license, my son's birth certificate, and portions of my tax return showing that I have claimed them as dependents. I find this extraordinarily invasive and onerous. Is this a standard procedure for large employers?
Yes companies are definitely verifying dependent information now. My corporation did it as well. It's formality. Although it may seem extreme, healthcare has revolutionized over the past decade. I think the tax returns may be a bit much. Otherwise, I wouldn't let it rattle you. Submit what they are asking you of before your enrollment deadline approaches.
