I think for certain employers this will make sense.
Congress / POTUS forced employees to defer certain SSI payments, or maybe it was executive action under POTUS. See CARES ACT. https://www.hwco.com/deferment-of-employees-portion-of-social-security-taxes/
In other W-2 Oddities, possibly related:
So when I see a value K of unknown terms in block 14 and add it to the miss-valued block 4 I get something really close to 6.2%: I think it will be a tax owed without penalty if you believe the article.
As is my block 4 is 4.3%. The mystery K value equal 1.6% 4.3% plus 1.6% = 5.9 % 0.5% off, off but I think many of you remember POTUS did something funny with our pay, deferring SSI in 2020 and it was not an action with my employer that I could get out of doing. Half of the difference is due in 2021 taxes and other half is due in 2022 per the above article.
