What deductions come out of my New Jersey paycheck?

If you work in New Jersey, understanding what deductions come out of your paycheck helps you plan your finances and avoid surprises. This guide is designed for employees, freelancers, and small business workers who want a clear breakdown of paycheck deductions, including taxes, state contributions, and common benefits.

1. Federal Taxes

Every paycheck in New Jersey is subject to federal taxes:

• Federal Income Tax: Withheld based on your W-4 form, filing status, and allowances. The more exemptions you claim, the less tax is withheld.
• Social Security Tax: 6.2% of gross wages (up to the annual limit), funding retirement and disability benefits.
• Medicare Tax: 1.45% of wages, plus an extra 0.9% for income over $200,000 (single) or $250,000 (married filing jointly).

Example: A monthly salary of $5,000 might have $775 deducted for federal taxes, Social Security, and Medicare combined.

2. New Jersey State Taxes

New Jersey applies progressive income tax rates from 1.4% to 10.75%. Your employer withholds state tax based on your NJ-W4 form.

• No local city tax: Unlike some states, New Jersey generally doesn’t charge additional municipal taxes.

Real-World Use Case: A resident earning $60,000 per year can expect around $2,400–$4,000 in state income tax annually, depending on allowances claimed.

3. Mandatory State Deductions

Certain state-specific contributions also reduce your paycheck:

• Temporary Disability Insurance (TDI): Provides short-term wage replacement for illness or injury.
• Unemployment Insurance (UI): Mainly employer-paid, but some employee contributions may appear.

4. Voluntary Deductions

Many employees choose additional deductions to cover benefits:

• Health, dental, and vision insurance premiums
• Retirement savings contributions (401(k), 403(b), or pension plans)
• Flexible Spending Accounts (FSA) or Health Savings Accounts (HSA)
• Other perks: life insurance, commuter benefits, union dues

Example: Contributing $200 monthly to a 401(k) reduces taxable income and helps grow retirement savings.

5. How Net Pay Is Calculated

Here’s a clear, detailed explanation of how net pay is calculated, tailored for a New Jersey employee:

How Net Pay Is Calculated

Net pay—also called take-home pay—is the amount you actually receive after all deductions are subtracted from your gross pay. Calculating it involves several steps:

1. Start with Gross Pay

Gross pay is your total earnings before any deductions. It includes:

• Base salary or hourly wages
• Overtime pay
• Bonuses or commissions

Example:
If you earn $5,000 per month in salary, your gross pay is $5,000.

2. Subtract Federal Taxes

Federal taxes include:

• Federal Income Tax: Based on your W-4 allowances and filing status
• Social Security Tax: 6.2% of gross wages (up to the annual limit)
• Medicare Tax: 1.45% of gross wages, plus 0.9% for high earners

Example:

• Federal Income Tax: $600
• Social Security: $310
• Medicare: $72.50
  Total Federal Deductions: $982.50

3. Subtract New Jersey State Taxes

• State Income Tax: Progressive rates (1.4% – 10.75%) based on income
• Temporary Disability Insurance (TDI): Small mandatory contribution

Example:

• NJ State Tax: $300
• TDI: $20
  Total NJ Deductions: $320

4. Subtract Voluntary Deductions

These include:

• Health, dental, or vision insurance
• Retirement contributions (401(k), pension)
• Flexible Spending Accounts (FSA) or Health Savings Accounts (HSA)

Example:

• Health Insurance: $250
• 401(k): $200
  Total Voluntary Deductions: $450

5. Calculate Net Pay

Formula:

Net Pay = Gross Pay – (Federal Taxes + State Taxes + Voluntary Deductions)

Example Calculation:

• Gross Pay: $5,000
• Federal Taxes: $982.50
• State Taxes & TDI: $320
• Voluntary Deductions: $450
  Net Pay = $5,000 – $1,752.50 = $3,247.50

Key Points to Remember

• Net pay is always less than gross pay due to mandatory and voluntary deductions.
• Adjusting your W-4 or NJ-W4 forms can change how much tax is withheld.
• Voluntary deductions reduce taxable income but also reduce take-home pay.
