The Federal Bracket Is Just the Starting Point
The 2026 federal brackets cap out at 37% for income over $640,600 single or $768,700 married filing jointly. Below that, the bracket jumps from 35% (top $250,525-$640,600 single) to 37% — a relatively narrow gap. The bigger surprise is the 24%-to-32% jump that hits between $203,300 and $258,550 for single filers. That's an 8-percentage-point step at exactly the income level where many professionals land.
But the federal bracket is only the first layer. High earners face a stack of additional taxes that compound the marginal rate. The Net Investment Income Tax (NIIT) adds 3.8% on investment income for taxpayers with modified adjusted gross income over $200,000 single or $250,000 married. The Additional Medicare Tax adds 0.9% on wages over the same thresholds — without the income-bracket gradient that protects lower earners.
Stack these on top of the federal bracket and the picture changes. A single earner at $250,000 faces a 32% federal bracket, plus 0.9% additional Medicare, plus 3.8% NIIT on any investment income — a true federal marginal rate of 36.7% on next-dollar wage income, or 35.8% on next-dollar investment income. That's before state tax. Add California's 9.3% bracket at this income, and your true marginal is 46% on wages and 45% on investment gains. New York City residents at this income face 52%.
The SALT Cap Is a High-Earner Tax
The State and Local Tax (SALT) deduction is capped at $10,000 — total — for state income tax, local tax, and property tax combined. For high earners in high-tax states, this cap is severe. A married couple in New Jersey with a $400,000 income and a $700,000 home easily pays $30,000 in state income tax and $15,000 in property tax. They can deduct $10,000. The remaining $35,000 is paid with after-tax dollars.
The SALT cap was set to expire after 2025 under the original Tax Cuts and Jobs Act, but legislative extensions have kept it in place through 2026. For couples in states like California, New York, New Jersey, Connecticut, and Massachusetts, the cap effectively raises federal taxable income by tens of thousands of dollars — even though that income was already taxed by the state.
The most reliable workaround for business owners is the Pass-Through Entity Tax (PTE) election, which over 35 states have adopted. By electing to have the entity pay state tax at the entity level, the deduction moves above-the-line and bypasses the SALT cap. This requires careful structuring and is only available to S-Corp and partnership owners — not W-2 employees.
The Net Investment Income Tax: An Easily-Overlooked 3.8%
Enacted in 2010 to fund the Affordable Care Act, the NIIT applies a 3.8% tax to net investment income for taxpayers above the $200,000/$250,000 MAGI thresholds. Crucially, the thresholds have not been indexed for inflation in over a decade — meaning more taxpayers cross them every year as wages rise.
The NIIT applies to: interest, dividends, capital gains, rental income, royalties, non-qualified annuity distributions, and most passive business income. It does not apply to wages, self-employment income, distributions from qualified retirement plans, or active business income.
The 3.8% rate is calculated on the lesser of (a) net investment income or (b) MAGI minus the threshold. So if you're at $210,000 MAGI with $50,000 of investment income, the NIIT applies only to $10,000 (the amount above $200K), not the full $50K. But for high earners with significant investment income, the full $50K typically gets taxed.
Key planning moves: harvesting investment losses to offset gains, holding investments in tax-deferred accounts where NIIT does not apply, considering municipal bonds where interest is exempt, and timing capital gains across tax years if you can drop below the threshold in alternate years.
AMT: Still Lurking for Specific Situations
The Tax Cuts and Jobs Act dramatically reduced AMT exposure starting in 2018, raising the exemption and phase-out thresholds. For 2026, the AMT exemption is $88,100 single / $137,000 married, with phase-outs beginning at $626,350 / $1,252,700. As a result, AMT now hits perhaps 200,000 returns per year — down from 5 million pre-TCJA.
But AMT is still a real issue for specific situations: large ISO exercises (the bargain element is an AMT preference item), high state and local tax payers (since SALT is added back for AMT), and taxpayers with significant private activity municipal bond interest. If you exercised ISOs and didn't sell in the same year, you must run AMT calculations to determine whether you've triggered the alternative tax.
The AMT rates are 26% on the first $239,100 of AMTI (2026) and 28% above that. For someone exercising 10,000 ISOs at a $50 spread per share, the $500,000 AMT preference item could create $130,000+ of additional federal tax in the year of exercise — potentially refundable as an AMT credit in future years if the resulting AMT exceeds regular tax.
Charitable Giving Strategies That Work Above $200K
Standard charitable deduction strategies — write a check, deduct the amount — are inefficient for high earners constrained by the SALT cap and standard deduction. The 2026 standard deduction is $16,100 single / $32,200 married. Many high earners barely clear it after the SALT cap, meaning small charitable contributions provide zero marginal benefit.
The fix is bunching: instead of donating $10,000 each year, donate $30,000 every three years through a Donor-Advised Fund. The DAF takes the deduction in year one (you itemize and exceed the standard deduction by $14,000), then distributes the funds to charities over the following years. Two-thirds of years you take the standard deduction; one-third you itemize at high effect.
For appreciated securities, donating the stock directly is dramatically more efficient than selling and donating cash. You avoid the capital gains tax on appreciation while taking a deduction at current market value. On $100,000 of appreciated stock with a $30,000 basis, this saves $14,000+ in capital gains tax (15% federal + 3.8% NIIT + state) compared to selling first.
For taxpayers over 70½ with traditional IRAs, Qualified Charitable Distributions (QCDs) up to $108,000 in 2026 (indexed) bypass the standard deduction issue entirely. The distribution counts toward your RMD but is excluded from AGI, which can reduce Medicare IRMAA premiums and Social Security taxation in addition to the charitable benefit.
Worked Example: $500K Earner in California vs Texas
Consider a married couple earning $500,000 in W-2 wages. In California, federal tax (using 2026 brackets and standard deduction) on $467,800 taxable income is approximately $116,900. FICA totals $20,800 (Social Security capped at $184,500, plus 1.45% Medicare on full salary, plus 0.9% additional Medicare on the $250,000 above threshold). California state tax on this income is approximately $43,500. Total: $181,200, leaving $318,800 take-home — a 36.2% effective rate.
In Texas with no state income tax, the same couple keeps $362,300 — $43,500 more annually. Over 10 years that's $435,000 in differential, before investment compounding.
Now overlay the SALT cap. In California, the $43,500 state tax is essentially fully non-deductible federally (since state + property already exceeded $10K). The federal tax was calculated correctly above. But the comparison clarifies the practical cost of California residency at this income: $43,500 less per year, plus the state tax is not federally deductible.
The break-even on relocating depends heavily on cost of living. A San Francisco family paying $80,000 in rent and $30,000 in additional cost-of-living expenses (vs Austin) loses much of the tax savings. A family that already plans to live somewhere mid-cost can capture nearly the full differential.
Roth Conversion Strategy in Lower-Bracket Years
High earners benefit enormously from Roth conversions during low-income windows: between leaving a job and starting Social Security/RMDs, during a sabbatical, or in early retirement before age 73. Converting $100,000 from a Traditional IRA to a Roth IRA in a 22% bracket year vs a 32% bracket year saves $10,000 — and that money grows tax-free forever.
The mechanics: there's no income limit on Roth conversions (unlike contributions). You pay ordinary income tax on the converted amount in the year of conversion. The Roth then has the standard advantages: tax-free growth, tax-free withdrawals after 59½ + 5-year rule, no RMDs during your lifetime, and tax-free inheritance for beneficiaries (though they must withdraw within 10 years).
Strategic timing: model the conversion to fill up a specific bracket. If you're in the 12% bracket with $40K of headroom before the 22% bracket, convert exactly $40K. Don't accidentally jump into 22% by converting too much. Build a Roth conversion 'ladder' across multiple years to systematically move pre-tax assets into Roth before RMDs begin.
The Mega Backdoor Roth is a related strategy for high earners with after-tax 401(k) contribution availability. You contribute up to the overall 401(k) limit ($69,000 in 2026, $76,500 with catch-up) including after-tax non-Roth contributions, then immediately convert those after-tax dollars to a Roth IRA. This sneaks $20,000-$30,000 of additional Roth contributions per year past the normal $7,000/$8,000 IRA limit and the $23,500 401(k) elective deferral limit.
