State Tax Guide for High Income Earners 2026: A Detailed Comparison for NY, NJ, IL, and FL

If you're earning $250,000, $500,000, or $1 million+, your choice of residence dramatically impacts how much you keep. A software executive earning $750,000 in Manhattan pays roughly $75,000 in state and city income taxes. That same person living in Miami? Zero state income tax. The difference over a 20-year career: $1.5 million.

But the decision isn't always straightforward. State income tax represents just one piece of the puzzle. Property taxes, sales taxes, estate taxes, and tax treatment of different income types all factor into your total tax burden. New Jersey offers generous retirement income exclusions. Illinois uses a flat tax that benefits very high earners. New York provides tax credits unavailable elsewhere, though its rate structure just shifted for 2026. And Florida's lack of income tax comes with tradeoffs in other areas.

This guide provides a detailed comparison of state taxes for high-income earners in New York, New Jersey, Illinois, and Florida for 2026. You'll learn how each state taxes wages, investment income, and business income, and what the real-world tax burden looks like at different income levels.

What's New for 2026

• New York's five lowest tax brackets dropped by 0.1 percentage point starting with tax year 2026, part of a two-step 0.2 point cut phasing in through 2027, while the top rates of 9.65%-10.9% were extended through 2032
• New York's estate tax exemption rose to $7,350,000 per individual for 2026, up $190,000 from 2025, with the dangerous "cliff" threshold now at $7,717,500
• Illinois maintains its flat 4.95% rate for 2026, unchanged and still the highest flat rate of any state
• Federal retirement contribution limits increased, with 401(k) limits rising to $24,500 and IRA limits to $7,500, affecting retirement planning strategies across all four states

How These Four States Compare: An Overview

Each state takes a fundamentally different approach to taxation, creating vastly different outcomes for high earners.

New York operates a highly progressive system with nine brackets from 3.9% to 10.9% for 2026, plus additional New York City tax up to 3.876% for city residents. Combined, high earners in NYC face up to roughly 14.8% state and local income tax, among the nation's highest, though the bottom brackets got slightly cheaper this year.

New Jersey uses seven brackets ranging from 1.4% to 10.75%, making it comparable to New York for top earners. However, New Jersey completely exempts Social Security and offers up to $100,000 (single) or $150,000 (married) in retirement income exclusions for those 62+. No local income taxes exist statewide, but property taxes average around $10,000—highest in the nation.

Illinois employs a flat 4.95% rate on all income regardless of amount, unchanged for 2026, making it more favorable for very high earners than progressive systems. The state taxes retirement income but offers full exemptions for those over 65. No local income taxes apply.

Florida has zero state income tax, creating the most dramatic difference for high earners. No tax on wages, investment income, business income, or retirement distributions. Property taxes vary significantly by county, and sales taxes run 6-8.5% combined.

Income Tax: Detailed State-by-State Breakdown

New York Income Tax for 2026

Real-World Tax Comparison: What You'll Actually Pay (2026 Rates)

Annual Income: $250,000 (Married Filing Jointly)

Annual savings vs. NYC: Living in Florida saves $23,075 per year. Over 20 years: $461,500.

Annual Income: $500,000 (Married Filing Jointly)

Annual savings vs. NYC: Living in Florida saves $49,195 per year. Over 20 years: $983,900.

Annual Income: $1,000,000 (Married Filing Jointly)

Annual savings vs. NYC: Living in Florida saves $102,825 per year. Over 20 years: $2,056,500.

Note: At this income level, Illinois remains more favorable than New Jersey due to its flat tax, while progressive New Jersey reaches higher rates.

Annual Income: $2,000,000 (Married Filing Jointly)

Annual savings vs. NYC: Living in Florida saves $210,085 per year. Over 20 years: $4,201,700.

Investment Income and Capital Gains

How each state taxes investment income matters enormously for high earners with significant portfolios or liquidity events.

Capital Gains Treatment

All four states tax long-term capital gains as ordinary income—none offers preferential rates like the federal system does.

• New York: Capital gains taxed at regular income rates up to 10.9% state plus 3.876% NYC for city residents.
• New Jersey: Capital gains taxed at regular rates up to 10.75%. A $1 million gain costs $107,500 in state tax (top bracket).
• Illinois: Capital gains taxed at flat 4.95% rate. A $1 million gain costs $49,500 in state tax regardless of your other income.
• Florida: Zero tax on capital gains. A $1 million gain costs $0 in state tax.

For entrepreneurs selling businesses or investors with large positions, the difference is staggering. Selling a business for $5 million in capital gains still costs several hundred thousand dollars in NYC or New Jersey, $247,500 in Illinois, or $0 in Florida.

Dividend and Interest Income

• New York: Taxed as ordinary income at rates up to 10.9% state plus 3.876% NYC. Interest from US government bonds and NY municipal bonds is exempt.
• New Jersey: Taxed as ordinary income at rates up to 10.75%. Interest from US government and NJ municipal bonds is exempt.
• Illinois: Taxed at a flat 4.95% rate. Interest from US government and IL municipal bonds is exempt.
• Florida: Zero tax on all dividend and interest income regardless of source.

Business Income and Self-Employment

Pass-Through Business Income

• New York: S corporation and partnership income taxed at individual rates up to 10.9% state plus 3.876% NYC. Unincorporated Business Tax (UBT) of up to 4% additional for NYC businesses.
• New Jersey: Pass-through income taxed at individual rates up to 10.75%. No additional business-level taxes.
• Illinois: Pass-through income taxed at flat 4.95% rate. Replacement tax of 1.5% additional on S corporations and partnerships (paid by entity), for an effective rate of 6.45% total.
• Florida: Zero tax on pass-through income. No entity-level taxes on S corporations or partnerships.

Self-Employment Tax

All states require federal self-employment tax (15.3% on net self-employment income up to the annual Social Security wage base, then 2.9% Medicare on amounts above). This federal tax applies regardless of state.

State income tax on self-employment income adds:

• Florida: No additional state tax
• Illinois: Add 4.95% state tax
• New Jersey: Add up to 10.75% state tax
• New York: Add up to roughly 14.8% combined state and city tax

Retirement Income: A Critical Difference

Comparison Table: Retirement Income Taxation

New York: Pensions and IRA distributions taxed at rates up to 10.9% state plus 3.876% NYC after the $20,000 pension exclusion (59½+). Government pensions are fully exempt.

New Jersey: Offers up to $100,000 (single) or $150,000 (married) in retirement income exclusions for those 62+, with phase-outs based on total income. A retiree with $150,000 in total retirement income can potentially owe $0 in NJ tax.

Illinois: Completely exempts all retirement income for those 65 or older, including pensions, 401(k), IRA distributions, and annuities. Under 65, retirement income is fully taxable at 4.95%.

Florida: No tax on retirement income at any age. Social Security, pensions, 401(k)/IRA distributions, and annuities are all completely tax-free.

Property Taxes: The Hidden Burden

While income taxes differ dramatically, property taxes significantly impact the total tax burden for homeowners.

Average Property Tax by State

New Jersey and Illinois property taxes partially offset their income tax advantages over Florida. A high earner saving $50,000 annually in state income tax by moving to Florida might face only $10,000-$15,000 more in property taxes for comparable housing, netting substantial savings.

Florida's homestead exemption reduces assessed value by up to $50,000, and caps annual assessment increases at 3%, providing long-term property tax protection. New Jersey offers homestead benefits and expanded ANCHOR relief programs for 2026.

Estate and Inheritance Taxes

Estate planning becomes critical for high net worth individuals, and state estate taxes vary dramatically.

State Estate Tax Comparison (2026)

New York raised its estate tax exemption to $7,350,000 for 2026, up $190,000 from 2025. New York uses a dangerous "cliff" provision: if your estate exceeds 105% of the exemption ($7,717,500 in 2026), you lose the entire exemption and pay tax on the full estate value, not just the excess.

Illinois imposes estate tax on estates exceeding $4 million with rates from 0.8% to 16%. An $8 million estate owes approximately $460,000 in Illinois estate tax.

New Jersey repealed its estate tax in 2018 but maintains an inheritance tax on certain beneficiaries. Siblings pay up to 16% on amounts over $25,000. Children, spouses, parents, and grandparents are exempt.

Florida has no estate tax and no inheritance tax at any level.

For ultra-high net worth individuals, avoiding NY estate tax or IL estate tax through Florida residency can save millions for heirs.

Sales and Other Taxes

• Florida: 6% state + up to 2.5% local = 6-8.5% combined
• Illinois: 6.25% state + up to 4.75% local = 6.25-11% combined (Chicago: 10.25%)
• New York: 4% state + up to 4.875% local = 4-8.875% combined (NYC: 8.875%)
• New Jersey: 6.625% state, no local = 6.625% statewide

Total Tax Burden: Comprehensive Comparison

Scenario: $500,000 Income, $1M Home, Married Filing Jointly

Florida advantage: ~$836,160 savings vs. NJ over 20 years; ~$1,171,900 vs. NYC.

Scenario: $1,000,000 Income, $2M Home, Married Filing Jointly

Florida advantage: ~$2,013,160 savings vs. NJ over 20 years; ~$2,432,500 vs. NYC.

Strategic Considerations for Residency Planning

When New Jersey Makes Sense

• Approaching retirement with pension income: The $100,000 (single) or $150,000 (married) retirement income exclusion for those 62+ provides enormous value.
• Work requires NYC access: Living in NJ suburbs while working in NYC provides lower property taxes than NYC itself.
• Southern NJ advantages: Lower property taxes with full access to Philadelphia jobs.

When Illinois Makes Sense

• Very high W-2 income: The 4.95% flat rate beats NJ (10.75%) and stays competitive with NY for million-dollar earners.
• Age 65+ retirees: Complete retirement income exemption plus lower cost of living than coastal states.
• Business owners: Pass-through income taxed at 6.45% total (4.95% + 1.5% replacement tax)—much lower than NJ or NY for high-profit businesses.

When New York Makes Sense

• Career growth: Unmatched opportunities in finance, media, arts, tech, and professional services often justify the tax cost.
• Lifestyle and culture: World-class amenities appeal to many high earners who value these over tax savings.
• The 2026 bottom-bracket cut offers marginal relief for those in lower income tiers, though top earners see no benefit.

When Florida Makes Sense

• High income of any type: Zero income tax means every additional dollar earned is only federally taxed.
• Liquidity events: Selling a business, exercising large stock options, or realizing substantial capital gains, Florida saves hundreds of thousands to millions.
• Retirement: No tax on any retirement income at any income level.
• Estate planning: No estate tax regardless of estate size, versus New York's $7,350,000 exemption with its punishing cliff.

How to Change Your State Residency

Essential Steps

Establish physical presence: Spend more than 183 days in your new state. High-tax states audit day counts aggressively.

Obtain new state credentials: Driver's license within 30 days, vehicle registrations, voter registration.

Establish new domicile: Purchase or lease residence in new state, sell or rent former residence, file homestead exemption if available.

Update all accounts and records: IRS address change (Form 8822), financial institutions, professional licenses, estate planning documents.

Sever ties with former state: Close or update bank accounts, cancel club memberships, end or clearly shift professional relationships.

Create audit trail: File Declaration of Domicile (available in Florida), keep moving receipts, document non-tax reasons for the move.

Special Considerations for NY/NJ Departures

New York and New Jersey aggressively audit high-income taxpayers moving to Florida or other no-tax states. Expect scrutiny if you're moving to a zero-tax state, income exceeds $500,000, a large income event occurs near the move date, or you maintain any property in the former state.

Protect yourself by: Moving 6-12 months before any large income event, maintaining meticulous day count records, completely severing property ownership, establishing deep ties in the new state immediately, and consulting tax professionals experienced in residency audits.
