That sux that they lumped that on your check, but it sounds like you worked it out in the long haul.Jimbo, watch OUT for the big "gotcha" they pull on their buyout offer. It got us BADLY.
They added it on our final paycheck AS IF it was a "bonus". Because of that, it cost each of us 36.9% combined taxes right off the top! That's Federal, State, and both SS taxes. In my case, it took enough out of it, that I could have lived on that tax deduction for 1 year! Also, they refused to put any of it into the 401k or any other tax shelter, because they claimed the Feds wouldn't allow it on a RIF package. When I filed my taxes the following year, because I in effect got double wages in one year, I only got back about 1/4 of the taxes they soaked me for.
Also, in my case I also qualified for full retirement, so I got a better payout IF I went that way, which I did even though I was only 56 at the time (end of Sept 2016 - 3 months short of being 57). I just turned 60 last month. So technically, I got the best combination of retirement AND the one year separation "perks" (full medical/dental, etc) they were offering others.
P.S. IF you are over the age of 55 and specifically lose your job due to a RIF, you can tap your 401k if needed WITHOUT paying the bonus 10% to the Feds. All you pay is the normal 20% off the top. You don't have to wait until age 59.5. In my case, I was able to pay off the house and get debt-free, and not touch the 401k until last year.
I haven't made the 59.5 mark yet, but close.
I do have the multiple of years and age in to retire, they go by 75 if I recall.
Some of the guys that are close are hoping for years and age and pay of 1,1 and 1 ....
I'd be happy with 0, 2, 2or 3 would be nice .... but it will never happen.
Back in the late 90's the company offered (via age and years I'm sure) but some of my friends back then left with between $150,000 and $350,000 in buy outs.
Those days are LLLLLOOOOOOONNNGGG gone.
I'm leaning toward the Lump Sum, but I know a few that took the annuities instead.
