Federal tax is calculated under federal rules, while state and sometimes local income taxes are calculated under separate rules. The result depends on taxable income, filing status, income type, where the taxpayer lives and earns income, and which deductions or credits apply. For tax year 2026, the federal top marginal rate is 37%, but that rate applies only to taxable income above the applicable threshold—not to all income.
How the federal tax brackets affect high earners
Federal individual income tax is progressive: the tax system applies different marginal rates to successive layers of federal taxable income. For tax year 2026, the seven federal individual income-tax rates are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The rate that applies to a layer depends on filing status and the bracket thresholds for that year.
The 37% bracket begins above $640,600 of taxable income for single filers and above $768,700 for married couples filing jointly in tax year 2026. The 35% bracket begins above $256,225 for single filers and above $512,450 for joint filers. These are taxable-income thresholds, not salary thresholds: deductions and other adjustments can make taxable income lower than gross income. The Internal Revenue Service’s 2026 figures are based on its 2025 announcement of inflation adjustments.
Marginal rate is not the rate on all income
The marginal rate is the rate on the next dollar of taxable income within a given bracket. As the IRS explains, “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.” A taxpayer whose income reaches the 37% bracket does not therefore pay 37% on every dollar.
#1 Best Overall
An effective rate is a different measure: total tax divided by a stated income measure. The result depends on what is counted as “total tax” and whether the denominator is gross income, adjusted gross income, or taxable income. There is no single effective rate that describes all high earners.
Why a state’s headline rate does not tell the whole story
States set their own individual income-tax rules. As of January 1, 2026, state systems fall broadly into three groups: no broad individual income tax, a flat-rate structure, or graduated rates. A flat-rate structure does not necessarily mean every income type or every dollar is treated identically; thresholds, exclusions, deductions, and special provisions can still matter. A state’s top rate alone also does not reveal its tax base or the amount a particular taxpayer owes.
“No broad individual income tax” does not mean residents pay no taxes. Sales, property, payroll, and other taxes are separate from the state income-tax comparison discussed here. The Tax Foundation’s 2026 state overview also notes county- or city-level income taxes in ten states; its comparison of average local effective rates uses 2023 data, the latest available for that comparison, and those averages should not be described as 2026 rates.
Washington is a notable qualification in that overview: its cited 7% and 9% rates concern high-earner capital-gains income, not a broad tax on wage income. That distinction illustrates why the type of income matters as much as the label attached to a state rate.

Why adding the federal and state top rates gives the wrong answer
Adding the federal top marginal rate to a state’s top rate does not calculate a taxpayer’s effective tax rate. The two rates may apply to different tax bases, may begin at different thresholds, and may not apply to all the taxpayer’s income. Local income taxes, special taxes, deductions, and credits can further change the result. State rules may also treat wages, business income, dividends, or capital gains differently.
A defensible comparison needs the taxpayer’s filing status and taxable income, the character and source of that income, the relevant state and local rules, residency and work-location facts, and applicable deductions and credits. Without those details, a headline-rate comparison is only one piece of the picture—not a personalized combined rate.
What happens when you live or work in more than one state?
Living in one state and earning income in another can create filing obligations in multiple states. Residency rules determine how a state treats its residents; source rules determine whether it taxes income connected to activity or property in that state. For example, Pennsylvania says nonresidents are taxed on Pennsylvania-source income. The relevant rules vary by state, so a move or a cross-border work arrangement should not be assumed to change tax residency automatically or leave only the home state involved.
Some states allow residents to claim a credit for qualifying income taxes paid to another state on the same income. Pennsylvania provides one example, but its credit has state-specific eligibility rules and limits. It is not a nationwide guarantee of full reimbursement. Other states have their own sourcing rules, residency definitions, reciprocity arrangements, credits, and documentation requirements. Remote-work sourcing in particular cannot be resolved without checking current official guidance for the states and income involved.

How the 2026 federal SALT deduction can affect the calculation
For tax year 2026, the overall federal deduction limit for state and local income, sales, and property taxes (SALT) is generally $40,400, or $20,200 for married filing separately. Under the IRS’s 2026 Form 1040-ES correction, the limit is reduced when modified adjusted gross income exceeds $505,000, or $252,500 for married filing separately. The limit cannot be reduced below $10,000, or $5,000 for married filing separately.
This is a deduction, not a credit or a dollar-for-dollar repayment of state taxes. For an eligible taxpayer who itemizes, a deduction can reduce the income subject to federal tax. Whether the taxpayer can use it, and how much, depends on filing status, itemization, eligible taxes paid, and the high-income phase-down. A high earner should not assume they can deduct the full limit.
A practical way to compare two tax situations
To compare two states or two work-and-residency arrangements fairly, use the same taxpayer facts for both sides and evaluate each jurisdiction’s current rules:
- Set the tax year and filing status. Brackets, thresholds, and deductions change, and filing status affects federal thresholds and some limits.
- Identify the income and its source. Separate wages, business income, dividends, capital gains, and other income where relevant; determine where each item is sourced under the states’ rules.
- Apply the federal calculation. Use federal taxable income and the correct tax-year brackets rather than applying the top marginal rate to all income.
- Apply each state and local system. Check tax bases, bracket thresholds, deductions, exclusions, special taxes, and applicable local income taxes.
- Check residency and cross-state relief. Determine which state treats the taxpayer as a resident, which states tax sourced income, and whether a credit or reciprocity rule applies and what limits it has.
- Review the federal SALT deduction. Establish whether the taxpayer itemizes, which taxes qualify, and whether the 2026 limit is phased down.
- Define any effective-rate comparison. State what taxes are included in the numerator and what income measure is used as the denominator.
For state-by-state filing decisions, use the relevant state revenue department’s current instructions. The Tax Foundation’s national table is a useful overview, but it is a secondary compilation and notes that some 2026 state standard-deduction or exemption adjustments were unavailable when it was prepared. Multi-state income, a move, or substantial investment income can warrant advice from a qualified tax professional.
