Do fringe benefits get deducted from your paycheck?

No a fringe benefit does not get "deducted" from your paycheck in a traditional manner. If you receive a check for $1000 and $250 are total taxes, then your net is $750. If you receive a check for $1200, which includes the $200 fringe, then taxes are $275, then your net is $275. The difference is that you have paid the taxes on the fringe benefit. Basically, your employer adds the fringe amount to your gross wages, figures the taxation, then removes the fringe to make is "wash".
