I’m looking at my W2 and I noticed that my wages, tips, and other compensation amount in box 5 is almost a 100k difference between that and my social security wages/base box (box 3). Even with the stocks that vested in 2021, this amount seems way more than what I actually got/TC. Is there other compensation that is included in that box that I don’t know about? Also sign on bonus wouldn’t be included in that, since this isn’t my first year at the company. TC: 190k YoE: 3
Box 3 caps out when the maximum Social Security withholding contribution is met.
