The New Jersey Paycheck Calculator estimates your take-home pay in one of the most complexly taxed states in the nation. New Jersey imposes a graduated state income tax with seven brackets ranging from 1.4% to 10.75%, making it one of the highest-taxed states for top earners. Beyond the income tax, New Jersey mandates several unique payroll deductions that appear on every employee's pay stub: State Disability Insurance (SDI at approximately 0.26%), Family Leave Insurance (FLI at approximately 0.06% of the first $161,400 of wages), and Unemployment Insurance/Workforce Development contributions (UI/WF combined at approximately 0.3825%). These mandatory state payroll taxes make New Jersey paychecks notably more complex than most other states. New Jersey's tax system is administered by the New Jersey Division of Taxation, and employers must withhold not only state income tax but also the SDI, FLI, and UI/WF contributions from every paycheck. The SDI program provides temporary disability benefits to workers who cannot work due to non-work-related illness or injury, while FLI provides wage replacement for workers taking leave to bond with a new child or care for a seriously ill family member. These programs are funded entirely by employee payroll deductions (unlike some states where employers also contribute to disability and family leave funds). The combined effect of these mandatory deductions is an additional approximately 0.7% of wages beyond the income tax. Compared to neighboring states, New Jersey's tax burden is among the highest in the region. New York has a top state rate of 10.9% plus NYC taxes up to 3.876%, making it comparable or higher for city residents. Pennsylvania has a flat 3.07% state rate (much lower than NJ), and Delaware has a top rate of 6.6%. Connecticut has a top rate of 6.99%. New Jersey's combination of high income tax rates plus mandatory payroll deductions makes it particularly expensive for middle-to-high-income earners. A worker earning $100,000 in New Jersey pays approximately $4,800 in state income tax plus $700 in SDI/FLI/UI contributions, totaling about $5,500 in state-level deductions. This calculator is essential for New Jersey workers across all income levels, from entry-level positions in the state's pharmaceutical and technology corridors to high-earning financial professionals who commute to New York City. Understanding the full scope of New Jersey paycheck deductions is critical for budgeting, salary negotiation, and comparing job offers across state lines.

- 1Enter your gross pay amount and select your pay frequency. New Jersey employers typically pay weekly, biweekly, semi-monthly, or monthly. Your gross pay includes base salary, overtime pay (at 1.5 times the regular rate), bonuses, commissions, and taxable fringe benefits. New Jersey's minimum wage is $15.13 per hour as of 2024 for most employers, one of the highest in the nation. For tipped workers, the cash minimum wage is $5.62 per hour plus tips. Include all forms of taxable compensation in your gross pay for an accurate calculation.
- 2The calculator computes federal income tax withholding based on your W-4 form elections. Your filing status, dependents, and any additional withholding amounts determine the federal tax deduction. The 2024 federal brackets range from 10% to 37%. Pre-tax deductions such as 401(k) contributions, health insurance premiums, HSA contributions, and FSA contributions reduce both federal and New Jersey taxable income. New Jersey conforms to most federal treatment of pre-tax deductions, meaning your 401(k) contribution reduces both federal and NJ state taxable income.
- 3New Jersey state income tax is calculated using the seven-bracket graduated system. For single filers, rates start at 1.4% on the first $20,000 and increase through several brackets to 10.75% on income over $1 million. For married filing jointly, the brackets are similar but with some differences in the lower brackets. New Jersey does not use the federal standard deduction; instead, it provides its own personal exemption of $1,000 per filer and $1,500 per dependent. New Jersey also does not allow itemized deductions for wages; the state uses its own system of above-the-line deductions and credits.
- 4The calculator applies New Jersey's mandatory payroll tax deductions beyond the income tax. State Disability Insurance (SDI) is withheld at approximately 0.26% of wages up to $161,400. Family Leave Insurance (FLI) is withheld at approximately 0.06% of wages up to $161,400. The combined Unemployment Insurance and Workforce Development (UI/WF) contribution is approximately 0.3825% of wages up to $42,300. These rates can change annually, so check the NJ Division of Taxation for the current year's rates. These deductions are unique to New Jersey and are not found in most other states.
- 5FICA taxes are calculated at the standard federal rates. Social Security is withheld at 6.2% on wages up to $168,600, and Medicare at 1.45% on all wages plus the 0.9% additional Medicare tax on wages over $200,000. Your employer matches the Social Security and Medicare base portions. FICA calculations are the same regardless of state.
- 6The calculator subtracts all mandatory taxes and voluntary deductions to produce your net take-home pay. For a typical New Jersey worker earning $80,000 filing single, the total mandatory deductions (federal tax, NJ state tax, NJ SDI/FLI/UI, and FICA) consume approximately 30-33% of gross pay, leaving about 67-70% as take-home before any voluntary deductions. This is higher than the national average due to New Jersey's state income tax rates and mandatory payroll deductions.
- 7Review your results and compare scenarios. New Jersey workers often benefit from modeling the impact of increasing retirement contributions (which reduce both federal and NJ taxable income), evaluating the cost of commuting to a New York City job (which adds NYC tax) versus working in New Jersey, or comparing job offers in New Jersey versus Pennsylvania (where the flat 3.07% rate is significantly lower). The calculator also helps verify your employer's withholding by comparing estimated figures to your actual pay stub.
Gross biweekly pay is $3,269.23. Pre-tax 401(k) at 5% equals $163.46. Federal taxable income: $85,000 minus $4,250 (401k) minus $14,600 equals $66,150. Federal tax: approximately $9,200 annually or $353.85 per period. NJ state tax on $80,750 (after 401k): approximately $3,500 annually or $134.62 per period. NJ SDI: $8.50. NJ FLI: $1.96. NJ UI/WF: approximately $12.50 (on first $42,300 only). FICA: $202.69 (SS) plus $47.40 (Medicare) equals $250.09. Total deductions: approximately $925. Net pay: approximately $2,344.
Gross semi-monthly pay is $6,250. Pre-tax 401(k) at 8% equals $500. Federal taxable income after 401(k) and MFJ deduction: $91,600. Federal tax after child credits: approximately $9,000 annually or $375 per period. NJ state tax on $138,000 (after 401k): approximately $6,200 annually or $258.33 per period. NJ SDI: $16.25. NJ FLI: $3.75. NJ UI/WF: capped early in year. FICA: $387.50 (SS) plus $90.63 (Medicare) equals $478.13. Total deductions: approximately $1,631. Net pay: approximately $4,619.
Gross monthly pay is $25,000. 401(k) contribution: $1,916.67. Federal taxable income: $262,400. Federal tax: approximately $5,350 monthly. NJ state tax on $277,000: approximately $14,800 annually or $1,233.33 monthly (mostly in the 6.37% bracket). NJ SDI: $35 (capped). NJ FLI: $8.08. NJ UI/WF: minimal (capped early). FICA: $1,550 average (SS capped mid-year) plus additional Medicare. Total monthly deductions: approximately $10,093. Net pay: approximately $14,907.
Pharmaceutical and biotechnology workers along New Jersey's central corridor (Route 1, Route 287, and the Princeton area), home to companies like Johnson and Johnson, Merck, Bristol-Myers Squibb, and hundreds of biotech firms, use this calculator to understand their complex NJ paycheck deductions. These workers often earn above-average salaries and face the upper NJ tax brackets. Understanding the combined impact of NJ income tax, SDI, FLI, and UI deductions is essential for accurate budgeting, especially when comparing offers from companies in neighboring lower-tax states.
Commuters who live in New Jersey and work in New York City represent one of the largest cross-border commuting populations in the nation. These workers must navigate both NJ and NY tax systems. While NJ provides a credit for income taxes paid to other states, the credit may not fully offset the higher combined NY state plus NYC tax burden. This calculator helps NJ residents estimate their NJ-side obligations and compare the net cost of commuting to NYC versus working at a NJ-based employer.
Small business owners and payroll administrators in New Jersey use this calculator to ensure correct withholding for employees. New Jersey's combination of graduated income tax, SDI, FLI, and UI/WF creates a more complex payroll calculation than most states. Employers must track the annual wage bases for SDI/FLI ($161,400) and UI/WF ($42,300) and stop withholding once employees exceed these thresholds. Errors in these calculations can result in penalties from the NJ Division of Taxation.
Military families stationed at Joint Base McGuire-Dix-Lakehurst and other New Jersey military installations use this calculator to understand New Jersey's tax impact on their income. Active-duty military members who maintain legal residency in another state may be exempt from NJ income tax on their military pay under the Servicemembers Civil Relief Act. However, civilian spouses working in New Jersey are subject to NJ taxes unless they qualify for the Military Spouse Residency Relief Act exemption. Understanding these rules is critical for military family financial planning.
NJ Residents Working Remotely for Out-of-State Employers
New Jersey residents who work remotely from home for employers based in other states owe NJ income tax on their wages since they are physically performing work in New Jersey. If the employer's state also claims taxing authority over the wages (as New York's convenience of the employer rule allows), the worker may face double taxation with only a partial NJ credit. New Jersey has challenged New York's convenience rule, but it remains in effect. Workers in this situation should consult a tax professional to optimize their filing strategy and minimize double taxation.
Dual-State Workers Splitting Time Between NJ and NY
Workers who split their workweek between a New Jersey office and a New York office must allocate their income between the two states based on days worked in each location. New York taxes income earned on days physically present in New York, and New Jersey provides a credit for taxes paid to New York. However, the credit is calculated on a per-return basis and may not perfectly offset if the NJ and NY effective rates differ. Workers must maintain detailed records of their work location each day to properly allocate income. This situation is extremely common in the NJ-NY metro area.
NJ Millionaire's Tax Impact on High Earners
New Jersey's top bracket of 10.75% applies to income over $1 million. This rate, combined with the federal top rate of 37% and the 0.9% Additional Medicare Tax, creates a marginal rate exceeding 48% on income above $1 million. For high-earning professionals in finance, pharmaceuticals, and technology, this makes NJ one of the most expensive states for top earners. Some high-income individuals have relocated to states like Florida or Texas to avoid this top bracket. Workers receiving large bonuses or stock option exercises that push total income over $1 million should plan for this bracket in their paycheck withholding.
| Taxable Income Range | Tax Rate | Cumulative Tax at Top of Bracket |
|---|---|---|
| $0 - $20,000 | 1.4% | $280 |
| $20,001 - $35,000 | 1.75% | $542.50 |
| $35,001 - $40,000 | 3.5% | $717.50 |
| $40,001 - $75,000 | 5.525% | $2,650 |
| $75,001 - $500,000 | 6.37% | $29,722.50 |
| $500,001 - $1,000,000 | 8.97% | $74,572.50 |
| $1,000,001 and above | 10.75% | — |
What are NJ SDI and FLI deductions on my pay stub?
SDI stands for State Disability Insurance, a mandatory employee-funded program that provides temporary disability benefits if you cannot work due to a non-work-related illness or injury. FLI stands for Family Leave Insurance, which provides wage replacement when you take leave to bond with a new child or care for a seriously ill family member. Both are mandatory payroll deductions in New Jersey and are funded entirely by employees (not employers). SDI is approximately 0.26% of wages up to $161,400, and FLI is approximately 0.06% of wages up to $161,400.
How does NJ tax compare to neighboring states?
New Jersey has among the highest state income tax rates in the region, with a top rate of 10.75% on income over $1 million. Pennsylvania is significantly cheaper with a flat 3.07% rate. Delaware's top rate is 6.6%. Connecticut tops out at 6.99%. New York's top state rate is 10.9%, but NYC residents pay an additional 3.078%-3.876% city tax. For a worker earning $100,000 filing single, approximate state income tax would be: NJ $4,800, PA $3,070, DE $4,200, CT $5,500, and NY (without NYC) $5,200.
Does NJ use the same standard deduction as the federal government?
No. New Jersey does not have a standard deduction that mirrors the federal standard deduction ($14,600 single, $29,200 MFJ in 2024). Instead, NJ provides personal exemptions of $1,000 per filer and $1,500 per dependent. This means your NJ taxable income is typically much higher than your federal taxable income. NJ also does not allow you to itemize deductions on your state return in the same way as on your federal return, though there are some NJ-specific deductions for medical expenses, property taxes, and certain other items.
If I live in NJ and work in NY, which state do I pay income tax to?
You pay New York state income tax (and NYC tax if you work in NYC) on your NY-source wages, and you file a NJ resident return reporting all income. NJ provides a credit for income taxes paid to other states, which offsets most or all of the NJ tax on your NY-source income. However, NJ's SDI, FLI, and UI/WF contributions still apply to your wages. In practice, most NJ residents working in NYC end up paying the higher of the two state tax amounts rather than both. The NJ credit prevents full double taxation but does not eliminate the NJ payroll deductions.
When do NJ payroll tax withholding caps take effect?
NJ has wage base caps on SDI/FLI (approximately $161,400 in 2024) and UI/WF (approximately $42,300 in 2024). Once your cumulative wages for the year exceed these thresholds, the corresponding deductions stop. The UI/WF cap is reached relatively early in the year for workers earning more than about $85,000, so you may notice slightly higher take-home pay in the second half of the year. Similarly, the federal Social Security wage base of $168,600 creates a bump in take-home pay once reached.
Does NJ tax retirement income like 401(k) and IRA distributions?
Yes, NJ taxes most retirement income including 401(k) distributions, traditional IRA distributions, and pension income, though there are exclusions. NJ provides a pension and retirement income exclusion of up to $100,000 for married filing jointly filers (or $75,000 for single filers) who are 62 or older or disabled, with income below $150,000. Social Security benefits are not taxed by NJ. These rules primarily affect retirees but are relevant for workers planning their retirement income strategy.
Pro Tips
If you live in New Jersey and have the option to work remotely rather than commuting to a New York City office, you may benefit from reducing your New York tax exposure. Days worked from your NJ home are taxed by NJ (not NY), and NJ's effective rate can be lower than the combined NY state plus NYC rate for many income levels. Keep a daily work location log and provide it to your employer so they can properly allocate your wages between states. Even one less day per week in NYC can save thousands annually.

New Jersey is home to more pharmaceutical and biotech companies per square mile than any other state in the nation, earning it the nickname 'The Medicine Chest of the World.' This concentration of high-paying pharmaceutical jobs means New Jersey has one of the highest median household incomes in the country (approximately $97,000), which also means many NJ workers fall into the upper state tax brackets. The irony is that while these workers earn premium salaries, NJ's high income tax rates, mandatory payroll deductions, and notoriously high property taxes (highest in the nation) consume a significant portion of those earnings.
