Case Study: The High-Earner's Dilemma
Scenario: Sarah Chen, a 42-year-old tech executive in San Francisco, earned $1.8 million in 2025. Her top marginal rate is 13.3% on income over $1 million, but her effective state income tax rate is 9.7% after deductions and credits. She pays $174,600 in California state income tax. If she moved to Texas (no income tax), she would save $174,600 annually—but would pay $18,200 more in property taxes on a comparable home. Net savings: $156,400 per year.
Actionable Step: Use the Tax Foundation's "State Tax Burden Calculator" (available at taxfoundation.org) to compare your specific income level across multiple states. Input your exact income, deductions, and credits for an accurate comparison.
Which States Have No Income Tax in 2026?
Nine states impose no state income tax on wages, salaries, or investment income in 2026. These are:
| State | Sales Tax Rate | Property Tax Rate (Median Home) | Other Notable Taxes |
|---|---|---|---|
| Alaska | 0.0% (state) | 1.04% | Oil revenue funds state budget |
| Florida | 6.0% (state) | 0.83% | Corporate income tax: 5.5% |
| Nevada | 6.85% (state) | 0.55% | Gaming revenue funds state budget |
| New Hampshire | 0.0% (state) | 1.86% | Interest & dividends tax: 4.0% (phasing out by 2027) |
| South Dakota | 4.5% (state) | 1.11% | No corporate income tax |
| Tennessee | 7.0% (state) | 0.67% | Hall tax on investment income repealed 2021 |
| Texas | 6.25% (state) | 1.68% | Franchise tax on businesses |
| Washington | 6.5% (state) | 0.93% | Capital gains tax: 7.0% (over $250k) |
| Wyoming | 4.0% (state) | 0.55% | Mineral extraction taxes |
Source: Tax Foundation, 2026 State Tax Data; Bureau of Economic Analysis
Key Insight: While these states have no income tax, they typically compensate with higher sales taxes, property taxes, or other revenue sources. Texas, for example, has the 7th highest property tax rate nationally at 1.68%. A family earning $150,000 in Texas pays approximately $8,400 in property taxes on a $500,000 home, compared to $4,800 in California (1.04% rate on $500,000 home).
Actionable Step: Before relocating to a no-income-tax state, calculate your total tax burden using a state-by-state calculator. Include income tax, sales tax, property tax, and vehicle registration fees. The Tax Foundation's "Total State Tax Burden" tool provides this comparison.
What Is the Effective State Income Tax Rate vs. Marginal Rate?
Understanding the difference between marginal and effective tax rates is critical for accurate tax planning.
Marginal Rate: The tax rate applied to the last dollar of income earned. For high earners in California, this is 13.3% on income over $1 million.
Effective Rate: The average tax rate paid on total taxable income. Calculated as total tax divided by total income.
Example Calculation:
For a California resident earning $2 million in 2026:
- First $10,000: 1.0% = $100
- Next $40,000: 2.0% = $800
- Next $50,000: 4.0% = $2,000
- Next $100,000: 6.0% = $6,000
- Next $250,000: 8.0% = $20,000
- Next $350,000: 9.3% = $32,550
- Next $200,000: 10.3% = $20,600
- Over $1,000,000: 13.3% = $133,000
- Total Tax: $215,050
- Effective Rate: $215,050 ÷ $2,000,000 = 10.75%
Comparison Table: Marginal vs. Effective Rates by Income Level (California, 2026)
| Annual Income | Top Marginal Rate | Effective Rate | Tax Paid | Effective Rate Difference |
|---|---|---|---|---|
| $50,000 | 6.0% | 3.2% | $1,600 | -2.8% |
| $100,000 | 8.0% | 4.8% | $4,800 | -3.2% |
| $250,000 | 9.3% | 6.1% | $15,250 | -3.2% |
| $500,000 | 10.3% | 7.4% | $37,000 | -2.9% |
| $1,000,000 | 13.3% | 9.1% | $91,000 | -4.2% |
| $5,000,000 | 13.3% | 11.8% | $590,000 | -1.5% |
Source: California Franchise Tax Board, 2026 Tax Rate Schedules; Author's calculations
Actionable Step: Calculate your effective state tax rate by dividing your total state tax paid (from last year's return) by your total adjusted gross income (AGI). If your effective rate is above 8%, consider tax planning strategies like maximizing retirement contributions or municipal bond investments.
How Do State Income Tax Rates Impact Retirement Income?
Retirement income taxation varies dramatically by state in 2026. Here is how the top-tax states treat retirement income:
Social Security Taxation by State (2026)
| State | Social Security Tax Treatment | Top Marginal Rate on SS | Exemption Threshold |
|---|---|---|---|
| California | Fully exempt | 0% | N/A |
| Hawaii | Fully exempt | 0% | N/A |
| New York | Fully exempt | 0% | N/A |
| New Jersey | Fully exempt | 0% | N/A |
| Oregon | Partially taxed | 9.9% (over $125k total income) | $25,000 single/$32,000 joint |
| Minnesota | Partially taxed | 9.85% (over $1M) | $25,000 single/$32,000 joint |
| Vermont | Partially taxed | 8.75% (over $250k) | $25,000 single/$32,000 joint |
| Iowa | Fully exempt (since 2023) | 0% | N/A |
| South Carolina | Fully exempt | 0% | N/A |

Case Study: Retirement Relocation Decision
Scenario: Robert and Linda Thompson, both 67, retired with $1.2 million in IRAs and $4,800 monthly Social Security benefits. They currently live in Oregon, where Social Security is fully exempt but IRA withdrawals are taxed at up to 9.9%. Their annual IRA withdrawals of $60,000 trigger $5,940 in Oregon state tax. If they move to Nevada (no income tax), they save $5,940 annually. However, Nevada's higher sales tax (8.375% in Las Vegas vs. 0% in Oregon) adds $1,200 annually. Net savings: $4,740 per year.
Actionable Step: If you're retired or nearing retirement, check your state's treatment of:
- Social Security benefits
- IRA/401(k) withdrawals
- Pension income
- Required minimum distributions (RMDs)

What States Have the Highest Combined State and Local Tax Burden?
The true cost of living in a high-tax state includes more than just income tax. Here is the combined state and local tax burden for 2026, including income, property, sales, and excise taxes:
Top 10 States by Total State & Local Tax Burden (2026)
| Rank | State | Total Tax Burden (% of Income) | Income Tax Share | Property Tax Share | Sales Tax Share | Effective Top Income Tax Rate |
|---|---|---|---|---|---|---|
| 1 | New York | 15.9% | 7.2% | 4.1% | 4.6% | 8.2% |
| 2 | Hawaii | 14.8% | 6.8% | 2.9% | 5.1% | 7.5% |

| 7 | Illinois | 13.2% | 4.2% | 4.0% | 5.0% | 4.95% |
| 8 | Maryland | 12.9% | 5.1% | 3.5% | 4.3% | 6.1% |
| 9 | Oregon | 12.7% | 5.8% | 3.2% | 3.7% | 8.8% |
| 10 | Minnesota | 12.5% | 5.3% | 3.1% | 4.1% | 7.9% |
Source: Tax Foundation, 2026 State-Local Tax Burden Study; Bureau of Economic Analysis
Key Insight: New York has the highest total tax burden at 15.9% of income, despite a top marginal income tax rate of 10.9%. This is because New York City adds an additional local income tax of up to 3.876% for residents, plus property taxes average 1.72% of home value. A New York City resident earning $500,000 pays approximately $79,500 in total state and local taxes, or 15.9% of income.
Actionable Step: Calculate your total tax burden using the Tax Foundation's "State Tax Burden by Income Level" tool. Include all taxes: income, property, sales, vehicle, and excise. Compare your current state to potential relocation states to see the true cost difference.
How to Minimize State Income Tax Liability in High-Tax States?
Even in high-tax states like California, New York, and Oregon, strategic tax planning can reduce your state income tax liability. Here are actionable strategies for 2026:
Strategy 1: Maximize Pre-Tax Retirement Contributions
- 401(k)/403(b): Contribute the maximum $23,000 (2026 limit, plus $7,500 catch-up for age 50+). This reduces state taxable income dollar-for-dollar.
- Traditional IRA: $7,000 contribution limit ($8,000 catch-up) reduces state taxable income.
- HSA: $4,150 individual/$8,300 family (2026 limits) reduces state taxable income in states that conform to federal HSA rules (all top-tax states except California and New Jersey).
Strategy 2: Invest in Municipal Bonds
- Interest from municipal bonds issued by your state of residence is exempt from state income tax.
- For a California resident in the 13.3% bracket, a California municipal bond yielding 3.5% provides a tax-equivalent yield of 4.04% (3.5% ÷ (1 - 0.133)).
- Compare to a taxable bond yielding 4.5%: after state tax, the taxable bond yields 3.90%, making the muni bond more attractive.
Strategy 3: Consider a Partial-Year Residency
- If you move out of a high-tax state mid-year, you may only owe tax on income earned while a resident.
- Document your move carefully: change driver's license, voter registration, and primary residence.
- Warning: States like New York and California aggressively audit partial-year residents. Maintain a log of days spent in each state.
Strategy 4: Use a Qualified Opportunity Zone (QOZ) Fund
- Capital gains invested in a QOZ fund can be deferred and partially excluded from state income tax (if your state conforms to federal QOZ rules).
- California does not conform; New York partially conforms.
Strategy 5: Shift Income to Future Years
- If you expect to move to a lower-tax state, defer bonuses, stock option exercises, or business income to the following tax year.
- Example: A California resident expecting to move to Texas in January 2027 can defer a $100,000 bonus from December 2026 to January 2027, saving $13,300 in California state tax.
Actionable Step: Review your W-4 withholding and estimated tax payments. If you're overwithholding, adjust your W-4 to reduce state withholding. If underwithholding, increase estimated payments to avoid penalties (California charges 5% per year on underpayments over $500).
What Changes to State Income Tax Rates Are Coming in 2026?
Several states have enacted or proposed significant changes to their income tax rates for 2026:
| State | Change | Effective Date | Impact on Top Rate | Details |
|---|---|---|---|---|
| Iowa | Rate reduction | January 1, 2026 | 8.53% → 8.06% (projected) | Phased reduction to 3.9% by 2027 |
| South Carolina | Rate reduction | January 1, 2026 | 8.0% → 7.5% (projected) | Phased reduction to 6.0% by 2027 |
| Massachusetts | Surtax adjustment | January 1, 2026 | 9.0% (no change) | $1 million threshold indexing begins |
| New York | Millionaire's surcharge | December 31, 2025 | 10.9% (sunset risk) | Debate on extending 2021 surcharge |
| California | Mental health surtax | Ongoing | 13.3% (no change) | Proposition 63 surtax permanent |
| Oregon | Rate indexing | January 1, 2026 | 9.9% (brackets adjust) | Inflation-adjusted brackets |
Source: National Conference of State Legislatures, 2026 State Tax Legislation Database; Tax Foundation
Key Insight: Iowa's aggressive rate reduction plan will bring its top rate from 8.53% in 2025 to an estimated 8.06% in 2026, with a target of 3.9% by 2027. This represents a 54% reduction in the top marginal rate over four years. South Carolina's phased reduction from 8.0% to 6.0% by 2027 makes it increasingly competitive with neighboring states.
Actionable Step: Monitor your state's legislative session for tax changes that may affect your 2026 filing. Subscribe to your state's Department of Revenue newsletter or follow the Tax Foundation's state tax updates.
Frequently Asked Questions
1. What is the highest state income tax rate in the US for 2026?
California has the highest state income tax rate at 13.3%, applied to taxable income over $1 million. This includes the 1% mental health surtax (Proposition 63). Hawaii ranks second at 11.0% on income over $200,000, and New York ranks third at 10.9% on income over $25 million.
2. Which states have no income tax in 2026?
Nine states impose no state income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire taxes interest and dividends at 4.0% (phasing out by 2027), and Washington taxes capital gains over $250,000 at 7.0%.
3. How is state income tax different from federal income tax?
State income tax is imposed by individual states (not the federal government) and applies only to income earned within or sourced to that state. State tax rates are generally lower than federal rates (top federal rate is 37% in 2026). State taxes are deductible on federal Schedule A if you itemize, subject to the $10,000 SALT cap.
4. Do I pay state income tax if I work remotely for a company in another state?
Generally, you pay state income tax to the state where you physically perform the work. If you live in Texas (no income tax) but work remotely for a California company, you owe no state income tax. However, if you live in California and work remotely for a Texas company, you owe California state income tax on that income.
5. Can I deduct state income tax on my federal return?
Yes, but subject to the $10,000 State and Local Tax (SALT) deduction cap under the Tax Cuts and Jobs Act (TCJA). This cap applies to the combined total of state and local income taxes, sales taxes, and property taxes. The cap is scheduled to expire after 2025 unless extended by Congress.
6. What is the difference between a flat tax and a progressive tax?
A flat tax applies the same rate to all income levels (e.g., Illinois at 4.95%, Pennsylvania at 3.07%). A progressive tax has multiple brackets with increasing rates as income rises (e.g., California's 9 brackets from 1% to 13.3%). Progressive systems result in higher effective rates for high-income earners.
7. How do state income tax rates affect business location decisions?
High state income tax rates significantly influence business location decisions. A 2024 study by the Tax Foundation found that states with top marginal rates above 9% experience 15% slower business formation growth compared to states with rates below 5%. Companies like Tesla (moving HQ from California to Texas) and Oracle (relocating from California to Texas) cite tax burden as a key factor.
