High earners do not pay one national income-tax percentage. Their bill depends on federal taxable income and filing status, plus the state—and sometimes city or county—where they live, work, or earn income. The 2026 federal top marginal rate is 37%, but that rate applies only to taxable income above the threshold for the taxpayer’s filing status; it is not the rate on all income.
Why a high earner has more than one income-tax calculation
Federal and state income taxes are separate calculations. The federal government applies federal rules to federal taxable income. A state applies its own definitions, rates, deductions, credits, and sourcing rules; a local jurisdiction may impose another income tax. As a result, the same income can be treated differently by different jurisdictions.
The outcome can also depend on whether income is wages, business income, dividends, capital gains, or another type; whether the taxpayer files singly or jointly; and where the taxpayer is a resident or performs work. A headline rate from one jurisdiction cannot, by itself, describe the total tax burden.
How the 2026 federal brackets affect high earners
The Internal Revenue Service’s 2026 federal individual income-tax rates are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. These are marginal rates: each applies to a layer of taxable income, rather than retroactively to every dollar. The IRS puts it this way: “When your income jumps to a higher tax bracket, you don’t pay the higher rate on your entire income. You pay the higher rate only on the part that’s in the new tax bracket.”

Where the top brackets begin
For tax year 2026, the 37% bracket applies to taxable income above $640,600 for a single filer and above $768,700 for a married couple filing jointly. The 35% bracket applies above $256,225 for single filers and above $512,450 for joint filers. These thresholds are taxable-income amounts, not gross salary. The IRS announced the 2026 rates and thresholds in 2025.
A marginal rate describes the rate on the next taxable dollar within the relevant bracket. An effective rate answers a different question: total tax divided by a specified measure of income. Any effective-rate comparison needs to state what taxes are included in the numerator and what income measure is used in the denominator.
How state and local income-tax systems differ
States do not share one income-tax structure. The Tax Foundation’s 2026 state individual income-tax table groups systems into three broad types, using rates and brackets as of January 1, 2026.
| State system | What the structure means | What a headline rate leaves out |
|---|---|---|
| No broad individual income tax | The state does not impose a broad individual income tax. | This does not mean residents pay no taxes; sales, property, payroll, and other taxes are separate from this comparison. |
| Flat-rate income tax | The state uses a flat-rate structure. | Thresholds, exclusions, deductions, and special provisions can still affect how income is taxed. |
| Graduated-rate income tax | Different rates apply across income brackets. | Bracket thresholds, deductions, exemptions, and special provisions affect the calculation, not just the top rate. |
The Tax Foundation compilation draws on state statutes, forms, and instructions, but it is a national overview rather than a substitute for the revenue department guidance used to prepare an individual return. Its authors noted that some 2026 state standard-deduction or exemption adjustments were not available when the table was prepared.
Local income taxes and special cases
The same 2026 table reports county- or city-level income taxes in ten states. It also presents average effective local rates using 2023 data, the latest available for that particular comparison; those averages should not be read as 2026 rates. Washington is a special case in the table: the cited 7% and 9% rates concern high-earner capital-gains income, not a broad tax on wages.
Why residency and income source can mean multiple state returns
A person who moves, works across state lines, or earns income from property or business activity in another state may have obligations beyond the state where they live. States define residency and source income under their own rules, so the relevant facts can include where someone lived during the year, where work was performed, and where income-producing activity occurred.
Pennsylvania’s official guidance, for example, says nonresidents are taxed on Pennsylvania-source income and distinguishes resident from nonresident treatment. Pennsylvania also allows a resident credit in some circumstances for qualifying income taxes paid to another state on the same income, subject to state-law limits. That is a Pennsylvania example, not a nationwide rule: eligibility, credit limits, reciprocity, sourcing, and documentation vary by state.

What the 2026 federal SALT deduction does—and does not do
The federal deduction for state and local taxes (SALT) can affect federal taxable income for taxpayers who itemize deductions. Under the IRS correction to the 2026 Form 1040-ES, the 2026 overall limit is generally $40,400, or $20,200 for married filing separately. The limit is reduced when modified adjusted gross income exceeds $505,000, or $252,500 for married filing separately, but cannot be reduced below $10,000, or $5,000 for married filing separately.
This is a deduction, not a credit or reimbursement: for an eligible itemizer, it reduces income subject to federal tax rather than directly refunding state taxes paid. Whether a taxpayer can use the full limit depends on filing status, itemization, eligible taxes paid, and the high-income phase-down.
How to estimate a combined tax burden responsibly
There is no defensible combined rate based only on a person’s income or on adding the federal and state top marginal rates. To compare two locations or estimate a particular household’s income taxes, hold the taxpayer facts constant and calculate each jurisdiction under the rules for the same tax year.
- Set the federal facts: identify filing status, federal taxable income, income types, and any federal deductions or credits that apply.
- Identify every relevant jurisdiction: determine residence, work locations, and the source of wages, business income, investments, or other income.
- Apply each state and local system: use the current rules for tax bases, brackets, deductions, special taxes, and local obligations.
- Check cross-state relief: determine whether a resident credit or reciprocity rule applies, and follow that state’s limits and documentation requirements.
- Apply federal SALT rules: establish whether the taxpayer itemizes and how the 2026 limit and phase-down affect the federal deduction.
- Define the comparison: if reporting an effective rate, specify which federal, state, and local income taxes are included and the income figure used as the denominator.
For state-specific filing decisions, use the relevant state revenue department’s current guidance. A tax professional may be useful when a return involves a move, multiple states, remote work, substantial investment income, or complex compensation.
