Summary
On a $10,000 bonus with $75,000 salary in New Jersey, the flat rate method results in $3,594 total tax (35.94%), leaving you $6,406 net.
New Jersey taxes your bonus at a 6.29% marginal state rate, adding $629 in state tax on top of federal withholding and FICA.
The flat rate method withholds a fixed 22% on bonuses up to $1 million. Above $1M, the excess is withheld at 37%. This is the most common method employers use.
The aggregate method combines your bonus with your regular pay, calculates tax on the total using marginal brackets, and subtracts what was already withheld on your salary.
Both methods produce the same federal withholding at your income level.
Bonus withholding is not a separate tax rate — both methods are just withholding approaches. Your actual tax liability is determined when you file your return.
