What is the New Jersey state income tax rate in 2026?
New Jersey taxes income in 7 brackets from 1.40% to 10.75% in 2026; the top rate starts at $1,000,000 of taxable income for a single filer and $1,000,000 for a married couple filing jointly. Example: a married couple, both 70, with $40,000 of Social Security, a $30,000 private pension and $30,000 of IRA withdrawals ($100,000 in all; the pension and IRA money split evenly between them) owes $0 of New Jersey income tax (0.0% of their income) and $5,087 of federal tax; a single 62-year-old with $24,000 of Social Security, an $18,000 pension and $18,000 of IRA withdrawals ($60,000 in all) owes $0 to New Jersey and $4,111 federal. The schedule, how New Jersey treats each kind of retirement income, and its local taxes follow.

How New Jersey taxes retirement income in 2026
| Standard deduction or personal exemption | $1,000 single, $2,000 married filing jointly, and the single amount for head of household. (New Jersey Division of Taxation; rules) |
|---|---|
| Social Security | Social Security benefits are fully exempt: none of the federally taxable amount enters the state base. (New Jersey Division of Taxation; rules) |
| Pensions, annuities and IRA/401(k) withdrawals | Pension, annuity and IRA/401(k) distributions: up to $75,000 excluded per taxpayer ($100,000 on a joint return) at age 62 or older. Above the first band the exclusion is a percentage of the whole pension (limited to the eligible amount), and the percentage falls with income (Social Security excluded from the income test): single and head of household 100% from $0; 37.5% over $100,000; 18.75% over $125,000; 0% over $150,000; married filing jointly 100% from $0; 50% over $100,000; 25% over $125,000; 0% over $150,000; married filing separately 100% from $0; 25% over $100,000; 12.5% over $125,000; 0% over $150,000. Married filing separately: the cap is $50,000. (New Jersey Division of Taxation; rules) |
| Age 65 and older | At age 65 or older: $1,000 is subtracted from the base ($2,000 for a married couple filing jointly when both qualify), against any income. (New Jersey Division of Taxation; rules) |
| Capital gains | Net long-term gain is taxed as ordinary income. Short-term gains are ordinary income. (New Jersey Division of Taxation; rules) |
Local income taxes: none in New Jersey. The local income taxes the tax engine computes for 2026 are in Delaware, Indiana, Iowa, Kentucky, Maryland, Michigan, Missouri, New York, Ohio, Oregon and Pennsylvania.

In our 510,000-path Monte Carlo study of 30-year retirement outcomes, New Jersey retirees finished at 70.57% success rate (ranked #46 of 51 by success rate, #47 of 51 by lowest median lifetime state tax). Median 30-year state-tax cost: $135,450 — that is $135,450 more than a Wyoming retiree pays. Median terminal balance after 30 years: $764,410. State tax is part of the optimization here — the playbook below shows the federal-state-ACA stack.
The NJ verdict
For a retiree planning withdrawals in 2026, New Jersey is one of the higher-burden states for retirees, especially on traditional pre-tax withdrawals. A top rate that starts above $1m, a pension exclusion from age 62, and an inheritance tax.
New Jersey allows a retirement-income exclusion of up to $100,000 for a couple from age 62. A traditional→Roth conversion draws on that same exclusion from age 62, so converting inside the cap can cost nothing at the state level.
Worked example: $30k Roth conversion in New Jersey
Consider a married couple age 58 in New Jersey with $75,000 of ordinary income (their MAGI), both on ACA Marketplace coverage. They want to convert $30,000 from a traditional IRA to a Roth. The New Jersey state tax on that conversion is approximately $3,225 — New Jersey's $100,000 retirement-income exclusion does not extend to conversion income at this age, so the full amount is taxed at 10.75%. Federal income tax adds another $3,600 — the whole conversion is taxed in the federal 12% bracket. And because the conversion pushes their MAGI to $105,000 — over the 400% FPL cliff of $84,600 — they lose their full ACA premium tax credit, $18,608 a year at New Jersey's average benchmark Silver premium. Total cost of the $30,000 conversion: about $25,433, or an effective 84.8% marginal rate. That state figure uses New Jersey's top bracket rate, so read it as a ceiling: a household whose income lands in a lower bracket pays less, and New Jersey's own deductions reduce it further. The federal-state-ACA stack matters in New Jersey.
Cost breakdown
| Component | Amount |
|---|---|
| Federal income tax (12% bracket) | $3,600 |
| New Jersey state income tax | $3,225 |
| ACA premium tax credit clawback | $18,608 |
| Total cost on $30,000 conversion | $25,433 (84.8% effective) |
Scenario B (high-tax): cliff-protective $15k conversion in New Jersey
A New Jersey couple aged 58 with $66K MAGI, both on a Silver-tier Marketplace plan converts only $15,000, which keeps their MAGI at $81,000, under the $84,600 400% FPL cliff. Staying under it matters because crossing it in New Jersey layers state tax, federal tax, AND the loss of the whole premium tax credit ($18,010 a year for this couple at $81,000) on top of each other. State tax on $15k: $1,612 — New Jersey's $100,000 retirement-income exclusion does not extend to conversion income at this age, so the full amount is taxed at 10.75%. Federal income tax added: $1,800 (the whole conversion is taxed in the federal 12% bracket). PTC preserved. Effective rate: 22.8%. In a high-tax state, the optimization is small annual conversions over many years — never a single 'big year' if Marketplace coverage is in play.
What the Monte Carlo data says about New Jersey
QuantCalc Research ran a 30-year, 10,000-path Monte Carlo simulation for an identical representative retiree (age 60, $2M starting balance, 60/40 portfolio, $80K real annual spend) in each of the 51 U.S. jurisdictions. Here's how New Jersey compared to the best- and worst-case states:
| Metric | New Jersey | Wyoming (best) | California (worst) |
|---|---|---|---|
| 30-year success rate | 70.57% | 77.11% | 69.03% |
| Rank (of 51) | #46 | #1 | #51 |
| Median lifetime state tax (30y) | $135,450 | $0 | $154,980 |
| Median total tax (30y) | $353,850 | $218,400 | $373,380 |
| Median terminal balance | $764,410 | $999,751 | $695,612 |
| Δ success vs Wyoming | -6.54 pp | — | −8.08 pp |

How New Jersey treats capital gains in retirement
New Jersey taxes long-term capital gains as ordinary income at the same top bracket rate (10.75%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 10.75% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.
Why the ACA cliff hits hard in New Jersey
The 400% federal-poverty-level cliff is federal, not state-specific — but its dollar impact depends on the benchmark Silver-plan premium in your county. New Jersey's Marketplace pricing and your household composition determine the size of the subsidy at risk. A couple aged 58 with MAGI of exactly $84,600 still has $17,652 a year of premium tax credit at New Jersey's average benchmark Silver premium, and all of it is on the line. With the 2021–2025 enhanced credit expired, $1 of additional MAGI above 400% FPL eliminates the entire credit.
For 2026 the 400% FPL threshold is:
- Household of 1: $62,600
- Household of 2: $84,600
- Household of 3: $106,600
- Household of 4: $128,600
Roth conversion strategy for New Jersey
The NJ-specific playbook depends on tier:
- Identify your cliff distance. Compute MAGI from all income sources (wages, capital gains, interest, dividends, traditional withdrawals). Find your headroom under 400% FPL. Use the live cliff widget above for a quick check.
- Stay under the cliff if you can. In New Jersey at 10.75%, the marginal cost of going over the cliff is federal tax + state tax + full PTC clawback. The break-even conversion size is smaller than in tax-free states.
- If you must go over, convert big. Once you've crossed the cliff, additional conversion dollars only cost federal + state tax (no incremental PTC loss). A "rip the bandage" conversion year can be efficient if you have many traditional dollars to move.
- Coordinate with capital gains and the 0% LTCG bracket. New Jersey taxes long-term capital gains as ordinary income at the same top bracket rate (10.75%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 10.75% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.
- Plan ahead for IRMAA. The IRMAA Medicare premium surcharge has a 2-year lookback. A New Jersey resident in their early 60s converting today will see IRMAA implications at 65. See RMD + IRMAA calculator for the lookback math.

Each move changes three bills at once: the federal return, the New Jersey return and, for anyone on Medicare, the IRMAA surcharge the 2026 income sets for 2028. Example: a married couple, both 72, with a $40,000 pension, $50,000 of Social Security, a $30,000 IRA withdrawal and $10,000 of long-term gains already realized in 2026, the pension, the IRA money and the conversion split evenly between them on the state return. Each row is that year with one move made, against the same year without it (negative = less tax).
| Move (by December 31, 2026) | Federal tax | New Jersey tax | IRMAA in 2028 |
|---|---|---|---|
| Convert $25,000 to a Roth IRA | $3,165 | $779 | $0 |
| Send $10,000 of the IRA withdrawal to charity as a QCD | −$1,200 | $0 | $0 |
| Harvest a $5,000 loss against the year's gains | $0 | $0 | $0 |

How much state income tax does a retiree pay in New Jersey?
It depends on the kind of income. In 2026, a married couple, both 70, with $40,000 of Social Security, a $30,000 private pension and $30,000 of IRA withdrawals ($100,000 in all; the pension and IRA money split evenly between them) owes $0 of New Jersey tax, and a single 62-year-old with $24,000 of Social Security, an $18,000 pension and $18,000 of IRA withdrawals ($60,000 in all) owes $0. Federal tax comes on top: $5,087 and $4,111.
Does New Jersey tax Social Security benefits?
No. Social Security benefits are fully exempt: none of the federally taxable amount enters the state base. (New Jersey Division of Taxation; rules)
Does New Jersey tax pensions, 401(k) and IRA withdrawals?
Pension, annuity and IRA/401(k) distributions: up to $75,000 excluded per taxpayer ($100,000 on a joint return) at age 62 or older. Above the first band the exclusion is a percentage of the whole pension (limited to the eligible amount), and the percentage falls with income (Social Security excluded from the income test): single and head of household 100% from $0; 37.5% over $100,000; 18.75% over $125,000; 0% over $150,000; married filing jointly 100% from $0; 50% over $100,000; 25% over $125,000; 0% over $150,000; married filing separately 100% from $0; 25% over $100,000; 12.5% over $125,000; 0% over $150,000. Married filing separately: the cap is $50,000. (New Jersey Division of Taxation; rules)
Does New Jersey have local income taxes?
No. No county, city or school district in New Jersey levies an income tax that the tax engine computes for 2026.
Does New Jersey tax Roth conversions?
New Jersey taxes Roth conversions as ordinary income at the state level. A $30,000 conversion by a couple aged 58 costs about $3,225 in state tax alone — New Jersey's $100,000 retirement-income exclusion does not extend to conversion income at this age, so the full amount is taxed at 10.75% — on top of federal tax and any ACA subsidy clawback. That state figure uses New Jersey's top bracket rate, so read it as a ceiling: a household whose income lands in a lower bracket pays less, and New Jersey's own deductions reduce it further.
What is New Jersey's 30-year Monte Carlo retirement success rate?
In QuantCalc's 510,000-path Monte Carlo study, a representative retiree in New Jersey (age 60, $2M balance, 60/40 portfolio, $80K real spend) finished 30 years at 70.57% success rate — ranked #46 of 51 jurisdictions. Median 30-year state tax: $135,450. Median terminal balance: $764,410.
What is the ACA cliff in New Jersey for 2026?
The ACA premium-tax-credit cliff is a federal threshold, not state-specific. For a household of two in 2026, it sits at 400% of the federal poverty level — $84,600. Crossing it by even $1 of MAGI eliminates the full subsidy now that the 2021-2025 enhanced credit has expired.
Is New Jersey a good state to retire for tax purposes?
New Jersey is one of the higher-burden states for retirees, especially on traditional pre-tax withdrawals. A top rate that starts above $1m, a pension exclusion from age 62, and an inheritance tax. In our Monte Carlo ranking it placed #46 of 51 jurisdictions.
Does New Jersey have a state estate or inheritance tax?
Yes — New Jersey has a state-level estate or inheritance tax in addition to the federal estate tax. Plan transfers accordingly.
How does New Jersey tax capital gains?
New Jersey taxes long-term capital gains as ordinary income at the same top bracket rate (10.75%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 10.75% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.
