Took this 401k post from a different thread may be useful if you have funds/money:
Just FYI to previous post, 401(k) contribution will not be deducted from severance pay. It’s considered supplemental pay/bonus, and retirement account contributions are not taken out. It also taxed at a higher rate like a bonus—I think around 40%.
May be too late, but if you think you are on the list, you might want to lower your 401k contribution. Not sure exactly how severance would work, but if it’s a lump sum, you might get a hefty chunk taken out as a contribution?
