How to Use This Payroll Tax Calculator
- 1
Enter gross wages
Input the employee's gross pay for the pay period. The calculator applies federal FICA rates (Social Security 6.2% up to $184,500 and Medicare 1.45% on all wages) plus New Jersey's withholding.
- 2
Select pay frequency
Choose weekly, biweekly, semi-monthly, or monthly. This affects how withholding is calculated since tax brackets are annualized. More frequent pay periods mean smaller per-check amounts.
- 3
Enter W-4 information
Input the filing status and any additional withholding requested on the employee's W-4. Post-2020 W-4s use a different calculation than the old allowance system.
- 4
Review employer and employee costs
The calculator shows both sides: employee deductions (federal tax, state tax, Social Security, Medicare) and employer costs (matching FICA, FUTA, state unemployment). Total employer cost is typically 7-12% above gross wages.
Example Calculation
Let's break down payroll taxes on a typical paycheck in New Jersey.
An employee earning New Jersey's median household income of $89,296/year, paid biweekly ($3,434 gross per check), single filer, no additional withholding. Per check: federal income tax ≈ $416, FICA ≈ $263, and New Jersey income tax ≈ $137.
Result: Employee take-home: approximately $68,088/year ($2,619/check) — an effective tax rate of 23.8%. Employers also pay a matching FICA share ($6,831/year) plus FUTA/SUTA, pushing total employer cost to roughly $96,627/year to employ this worker — 7-11% above salary.
What Affects Your Results
Federal FICA
Social Security (6.2% employee + 6.2% employer on first $184,500) and Medicare (1.45% + 1.45% on all wages, plus 0.9% employee-only above $200K). These are non-negotiable, flat-rate taxes.
State Income Tax
Ranges from 0% (9 states) to 13.3% (California top bracket). New Jersey's rate structure (flat vs. progressive) significantly affects take-home pay.
Unemployment Insurance
FUTA (federal) is 6% on first $7,000, reduced to 0.6% with state UI credit. SUTA (state) rates vary by employer claims experience — rates as low as 0.1% or as high as 5.4%+.
Pre-Tax Deductions
401(k) contributions, HSA, health insurance premiums, and FSA contributions reduce taxable wages. Maximizing pre-tax deductions is the most effective way to increase take-home pay.
Tips for New Jersey Residents
- Use the IRS Tax Withholding Estimator annually (irs.gov) to check if your W-4 is accurate. Owing $1,000+ or getting a $2,000+ refund means your withholding needs adjustment.
- Know New Jersey's unemployment insurance rate — it varies by your claims history. Rates range from 0.5% to 5.4% and can add significant cost. Minimizing turnover directly reduces SUTA rates.
- Social Security tax has a wage cap ($184,500 for 2026). Employees who hit this mid-year see a temporary net pay increase in late-year paychecks. Employers stop matching at the same threshold.
- The additional Medicare tax (0.9%) kicks in at $200,000 for single filers. This is employee-only — no employer match. High earners should plan for this in their withholding.
- For employers: consider using a payroll service (Gusto, ADP, Paychex). The cost ($40-$150/month + $6-$12/employee) is trivial compared to the penalty risk of self-filing payroll taxes incorrectly.
