Today at work i was called into my manager (and owners) office. i was told that the person doing payroll took FICA out wrong. the percentage was supposed to be 7.56%. they charged $7.56. stupid i know. anyways. so they are now expecting me to pay for their mistake $277.50 in my next 3 paychecks. i have no way of even proving anything because they dont give me a check stub, they pay us w/ business checks w/ our deductions written in the memo. so the moment you cash it you have no papers for your records. can they do this? and can they give me a check w/o a stub? i heard they could only not give you a stub the first $600, i've been there since march. i just dont know what to do or who to even talk to. plz help!!!!! :confused:

Well, actually, it's 7.65% (6.2% for OASDI, 1.45% for Medicare).

First of all, $600 has nothing to do with employees; it is the threshhold above which independent contractors must receive 1099-MISC forms at year-end.
So, forget the $600 thing.

Secondly, paystubs. All Kansas law requires is that you receive a statement of itemized deductions upon your request; there is no requirement that such statements be automatically provided. However, I suggest that you now make this request for the pay periods for which they say you were under-deducted.

If in fact you were under-deducted, yes, they can deduct the shortage from your pay. See the question here about overpayments which, in effect, is what the under-deduction resulted in.
