How to Calculate New Jersey Paycheck with Dependents

If you live and work in New Jersey, understanding how to calculate your paycheck with dependents is essential to plan your budget, manage taxes, and maximize take-home pay. This guide is for employees, freelancers, and hourly workers in New Jersey who want a clear breakdown of deductions, tax impacts, and real-world paycheck examples.

1. Determine Your Gross Pay

Gross pay is your total earnings before any deductions.

• Hourly workers: Multiply your hourly wage by the hours worked.
  Example: $22/hour × 40 hours = $880 gross pay.
• Salaried employees: Divide annual salary by the number of pay periods.
  Example: $55,000/year ÷ 26 pay periods = $2,115.38 per paycheck.

2. Factor in Federal Tax Withholding for Dependents

Dependents affect your federal income tax withholding:

• Complete IRS Form W-4 to claim dependents.
• Each dependent can reduce federal tax withheld from your paycheck.
• Use the IRS Tax Withholding Estimator to adjust your W-4 accurately: irs.gov/W4.

Example: Claiming two dependents may reduce your federal withholding by approximately $150 per bi-weekly paycheck.

3. Calculate New Jersey State Income Tax

New Jersey state income tax is progressive and depends on taxable income:

1. Start with gross pay minus pre-tax deductions (retirement contributions, health insurance).
2. Apply NJ tax brackets based on your filing status.
3. Claim dependents on the NJ-W4 form to lower state withholding slightly.

Example: A single employee earning $2,000 per paycheck with one dependent may see NJ withholding of about $60 instead of $70.

4. Account for Payroll Taxes

All employees pay mandatory payroll taxes:

• Social Security: 6.2% of gross pay
• Medicare: 1.45% of gross pay
• NJ Unemployment Insurance (UI): Small percentage
• NJ Disability Insurance (DI) & Family Leave Insurance (FLI): Combined small percentage

These deductions are standard and unaffected by dependents.

5. Deduct Pre-Tax Contributions

Pre-tax contributions lower taxable income and increase net pay:

• 401(k) or 403(b) retirement contributions
• Health insurance premiums
• Health Savings Account (HSA) or Flexible Spending Account (FSA)

6. Calculate Net Pay

Finally, subtract all taxes and deductions from gross pay: Net Pay=Gross Pay−(Federal Tax+NJ Tax+Payroll Taxes+Pre-Tax Deductions)\text{Net Pay} = \text{Gross Pay} – (\text{Federal Tax} + \text{NJ Tax} + \text{Payroll Taxes} + \text{Pre-Tax Deductions})

Real-Life Example:

• Gross Pay: $2,000
• Federal Tax Withholding (2 dependents): $220
• NJ State Tax: $60
• Payroll Taxes (SS, Medicare, UI, DI, FLI): $153
• Health Insurance: $100

Net Pay: $2,000 − $220 − $60 − $153 − $100 = $1,467
