Quick Answer
Shift differential pay is extra compensation for working undesirable hours, typically 10-25% above base hourly rate. For example, if you earn $20/hour normally, a 15% night shift differential would pay $23/hour ($3 extra per hour). This premium is taxed as regular wages at your normal withholding rate.
