How much will the government deduct from my part-time job paycheck?

I work full-time, 40hours per week @ $9.50/hour. I will have a 16hour/biweekly part-time job @ $12.00/hour. What percentage of my part-time job paycheck will be paid to the federal government and the state of New Jersey? Will social security or medicare be deducted from my part-time job paycheck?

Nothing. Your employer will deduct taxes, including Social Security and Medicare from your paycheck.

Yes, ss and medicare, totalling 7.65%, will be taken out of your part time job's paycheck. What is deducted for income tax will depend on how you fill out your W-4, but the federal income tax will be around 15% if you are single - if not enough is deducted, you'll owe the rest when you file your tax return. New Jersey tax will be in addition to federal.
