How to Calculate Your True Tax Burden Before Choosing a State to Live In

The Single-Rate Fallacy

Nine states collect no personal income tax. That fact drives relocation decisions worth hundreds of thousands of dollars. It also tells an incomplete story.

A household earning $400,000 annually in California pays a 9.3% marginal state income tax rate on income above $66,295. That is a real and significant cost. But a comparable household that moves to Texas to escape it will pay an average effective property tax rate of 1.74%, versus California's 0.76%. On a $1.2 million primary residence, that differential alone is $11,760 per year. Add sales tax, and Texas collects 8.19% on average at the combined state and local level. California collects 8.68%. That gap is $490 per $100,000 in taxable spending.

The income tax savings are real. The offset from other taxes is also real. You need to run both numbers before making a decision of this magnitude.

The Four Tax Categories That Determine True Burden

1. State Income Tax

This is the most visible category. State income tax rates range from 0% (Texas, Florida, Nevada, Washington, Wyoming, South Dakota, Alaska, Tennessee, and New Hampshire on wages) to 13.3% in California. But the rate structure matters as much as the top rate.

A $300,000 W-2 earner in New York pays an effective state income tax rate of approximately 6.85% after accounting for the graduated brackets, not the top marginal rate of 10.9%. That yields roughly $20,550 in state income tax on $300,000. The same earner in Georgia pays a flat 5.49%, or $16,470. The gap is $4,080. Meaningful, but not the entire story.

Capital gains treatment adds another variable. California taxes capital gains as ordinary income at rates up to 13.3%. Most other states apply preferential rates or no tax at all. An investor realizing $500,000 in long-term capital gains pays $66,500 to California in state tax alone. That same gain is taxed at 0% in Nevada.

2. Property Tax

Property tax is the most underestimated component for high-net-worth households. Effective rates vary from 0.27% in Hawaii to 2.23% in New Jersey. On a $2 million home, that range produces annual property tax bills between $5,400 and $44,600.

The effective rate, not the statutory rate, is what matters. Effective rate equals the actual tax bill divided by the market value of the property. Many states assess property at a fraction of market value, then apply their nominal rate to that lower figure. Always calculate effective rate.

3. Sales Tax

Sales tax is a function of spending behavior, not income. High-income households spend more in absolute terms but typically less as a percentage of income. Still, at $250,000 in annual taxable consumption, a 2% difference in combined state and local sales tax rates costs $5,000 per year.

Oregon, Montana, New Hampshire, and Delaware collect no sales tax. Louisiana and Tennessee exceed 9.5% at the combined average level. For households that spend heavily on taxable goods or make large one-time purchases such as vehicles or boats, this differential accumulates quickly.

4. Estate and Inheritance Tax

This category affects long-term wealth transfer, not annual cash flow. Twelve states and the District of Columbia impose estate taxes. Six states impose inheritance taxes. Maryland imposes both.

The federal estate tax exemption sits at $13.61 million per individual in 2024, scheduled to revert to approximately $7 million in 2026 unless Congress acts. State exemptions are often far lower. Massachusetts and Oregon exempt only $1 million. A taxable estate of $3 million in Massachusetts pays state estate tax at a marginal rate of up to 16%, potentially costing $320,000 or more in state estate tax that would not exist in Florida.

Worked Example 1: California vs. Nevada, $450,000 Income

Consider a single professional earning $450,000 in W-2 wages. She owns a $1.5 million home. She spends $180,000 per year on taxable goods and services.

California:

• State income tax: approximately $38,400 (effective rate ~8.53%)
• Property tax: $1,500,000 x 0.76% = $11,400
• Sales tax on $180,000: $180,000 x 8.68% = $15,624
• Total state and local tax burden: $65,424
• As a percentage of gross income: 14.5%

Nevada:

• State income tax: $0
• Property tax: $1,500,000 x 0.55% effective = $8,250
• Sales tax on $180,000: $180,000 x 8.23% = $14,814
• Total state and local tax burden: $23,064
• As a percentage of gross income: 5.1%

The annual differential is $42,360. Over 10 years, assuming 5% annual income growth and consistent spending patterns, the cumulative difference compounds past $530,000 before investment returns on the retained capital.

That is the number worth relocating for. Not the top marginal rate headline.

Worked Example 2: Texas vs. Illinois, $250,000 Income

Now consider a married couple earning $250,000, owning a $600,000 home, spending $120,000 annually on taxable goods.

Texas:

• State income tax: $0
• Property tax: $600,000 x 1.74% = $10,440
• Sales tax on $120,000: $120,000 x 8.19% = $9,828
• Total state and local tax burden: $20,268
• As a percentage of gross income: 8.1%

Illinois:

• State income tax: $250,000 x 4.95% flat = $12,375
• Property tax: $600,000 x 2.07% effective = $12,420
• Sales tax on $120,000: $120,000 x 8.81% = $10,572
• Total state and local tax burden: $35,367
• As a percentage of gross income: 14.1%

Texas saves this household $15,099 per year. But this example also demonstrates that Texas's property tax rate nearly offsets its income tax advantage. At a $300,000 home, the Texas savings compress significantly. At an $800,000 home, the property tax differential begins cutting into the income tax advantage.

The breakeven point matters. Run the numbers at your actual property value.

Variables That Shift the Calculation

Income Composition

A retired household drawing primarily from Social Security and a pension faces a fundamentally different tax profile than a W-2 earner. Thirty-eight states exempt Social Security income from taxation. Some states exempt pension income partially or fully. A retiree in Mississippi with $120,000 in combined retirement income may pay near-zero state income tax. The same income in Vermont faces meaningful taxation.

Remote Work and Business Income

Business owners and remote workers must confirm domicile rules. California aggressively audits former residents for income sourced to California. If you maintain business relationships, clients, or a physical office in a high-tax state after relocating, that state may assert taxing authority. Changing your drivers license and voter registration is necessary but not sufficient to establish new domicile.

Planned Major Purchases

A family buying a $100,000 vehicle in Florida (no income tax, 6% sales tax) pays $6,000 in sales tax. The same purchase in New Hampshire costs zero. Planned purchases of boats, aircraft, and high-value goods should factor into the state-by-state comparison before the purchase date.

How to Build Your Own Comparison

Run this calculation in four steps.

First, determine your adjusted gross income, and separately identify capital gains, dividend income, and retirement distributions. Tax treatment varies by category across states.

Second, identify your actual property value and look up the effective property tax rate for the specific county you are considering, not the statewide average. County-level data is available from each state's Department of Revenue and from the Lincoln Institute of Land Policy's 50-State Property Tax Comparison.

Third, estimate annual taxable spending. Exclude groceries and prescription drugs where applicable, as many states exempt these categories.

Fourth, calculate estate exposure. If your net worth exceeds $1 million, map your estate against the exemption thresholds of each candidate state.

Add the four categories. Divide by gross income. That percentage is your true total state and local tax burden. Compare it across states on identical terms.
