How to Calculate New Jersey Paycheck with Dependents

If you live or work in New Jersey and claim dependents, your paycheck won’t look exactly like someone with the same salary who claims none.
That’s because dependents directly affect how much tax your employer withholds from your pay. Knowing how to calculate your New Jersey paycheck with dependents helps you understand your take-home pay and avoid surprises at tax time.

Let’s go through how it works, step by step.

Start with Your Gross Pay

Your gross pay is your total earnings before any deductions or taxes.
If you earn a salary, divide it by the number of pay periods per year:

• Weekly: 52 paychecks
• Biweekly: 26 paychecks
• Monthly: 12 paychecks

Example:
If your annual salary is $65,000 and you’re paid biweekly, your gross per paycheck is:
$65,000 ÷ 26 = $2,500.

This is your starting point before any taxes or deductions.

Understand How Dependents Affect Withholding

Dependents reduce your taxable income through withholding allowances.
When you complete your NJ-W4 form, you list the number of dependents you’re claiming. Each dependent gives you an allowance that tells your employer to withhold less state income tax.

Here’s what that means:

• More dependents = lower withholding = higher take-home pay
• Fewer dependents = higher withholding = larger tax refund later

Keep in mind that dependents do not change your FICA taxes (Social Security & Medicare), only income-tax withholding.

If you’re unsure what to claim, the New Jersey Division of Taxation offers an NJ-W4 worksheet.

Apply Federal and FICA Taxes

Before state taxes are withheld, your paycheck also has:

• Federal Income Tax — based on your W-4 and filing status
• Social Security (6.2%)
• Medicare (1.45%)

Dependents can reduce your federal tax withholding, but they don’t affect your Social Security or Medicare deductions.
After these federal taxes, your employer applies New Jersey’s state income tax and payroll deductions.

Apply the New Jersey State Income Tax Rate

New Jersey has progressive tax brackets, meaning higher earners pay higher rates.
Here are the 2025 brackets for single filers:

Taxable Income	State Tax Rate
Up to $20,000	1.4 %
$20,001 – $35,000	1.75 %
$35,001 – $40,000	3.5 %
$40,001 – $75,000	5.525 %
$75,001 – $500,000	6.37 %
$500,001 – $1 million	8.97 %
Over $1 million	10.75 %

Married filers share roughly double those thresholds.

Employers apply these brackets to your adjusted taxable income per pay period, factoring in your number of dependents.

Include State Payroll Deductions

In addition to income tax, every New Jersey paycheck includes small state-run program deductions, such as:

Deduction	Typical 2025 Rate	Purpose
Unemployment Insurance (UI)	≈ 0.3825 %	Supports workers who lose jobs
Disability Insurance (DI)	≈ 0.47 %	Covers off-the-job injury/illness
Family Leave Insurance (FLI)	≈ 0.09 %	Provides paid family-care leave
Workforce Development Fund	≈ 0.0425 %	Funds job-training programs

These aren’t affected by dependents, but they’re part of the total deductions that reduce your net pay.

Example: Calculating a Paycheck with Dependents

Let’s estimate for a married filer earning $65,000/year, paid biweekly, with two dependents.

Step	Description	Amount
Gross Pay	Annual $65,000 ÷ 26	$2,500
Federal Tax	Approx. 12 %	$300
Social Security	6.2 % of gross	$155
Medicare	1.45 % of gross	$36
NJ State Tax	Reduced for 2 dependents (~4.8 % eff.)	$120
NJ UI/DI/FLI	≈ 0.8 % combined	$20
Estimated Take-Home		≈ $1,869 per check

This is a simplified example—your exact result may differ depending on benefits or pre-tax deductions.

Tips to Optimize Your Paycheck with Dependents

• Update your NJ-W4 when your family changes (birth, adoption, dependents leaving home).
• Use pre-tax benefits like a 401(k) or HSA to reduce taxable income.
• Double-check withholding after major life events or job changes.
• Review annually before tax season to avoid under- or over-withholding.

If your take-home feels lower than expected, compare it using your site’s Paycheck Deductions Calculator.
