Employer messed up my 401k start date and lost match

“My previous employer had taken deductions from my paychecks for a 401k. I worked there from 2023-2025, where I was under the impression there was a 401k account with fidelity that my retirement would be going to.”source ↗
“Lo and behold fidelity has nothing for me on file. I’ve spent the past two weeks searching with the DOL and state databases to see if anything under my social existed. My previous employer is directly ignoring my emails and calls both at corporate and hr levels.”source ↗
“I contacted ADP and they have no record of a 401k attached to my account despite my pay history claiming money was taken. My statements and paystubs say the same.”source ↗
“So I started with this company 4 years ago. 401k was supposed to kick in after 4 months. I waited nothing. I asked my boss she told me it should start automatically when I am eligible. I waited. I waited nothing. I ask her again she tells me it should be automatic again. So I wait. Now its well past when it should have started like 2 years. I call the payroll company, when I was hired my employer listed my birthday as the day I was hired so because I wasnt 18 years old(im 47)I wasnt eligible for 401k. They didnt notice I was zero years old? What can I do? What should I do? Any help would be great!”source ↗
“I'm helping my parents clean up an IRA mistake and want to make sure we're handling this correctly.”source ↗
“My mom made these Roth IRA contributions... That leaves the older excess contributions... 14,000 total historical excess”source ↗
“I'm mainly looking for people who have dealt with the same multi-year excess Roth/Form 5329 situation.”source ↗
