With the passing of the OBBBA, how might some high-income earners pay more in taxes?
In 2026, the top federal tax rate remains at 37%. On the surface, that suggests little has changed for high-income households. Yet some may still experience a higher tax burden, even if their income remains consistent.
The reason is not a rate increase, but how income is taxed. Elements such as the Alternative Minimum Tax (AMT), reduced effectiveness of deductions, and adjusted income thresholds can alter after-tax results without affecting the headline rate.
This reframes how planning decisions are evaluated. Rather than focusing on the top rate alone, the emphasis moves toward how income, deductions, and timing interact.
In this article from Jupiter Wealth Management in Denver, Colorado, we break down how deductions, tax brackets, AMT, and income timing may lead to higher taxes in 2026.
How Do Deduction Limits Affect High-Earners in 2026?
There are three areas where deduction limits affect high-income earners: the overall itemized deduction limit (often referred to as the 2/37 rule), the state and local tax (SALT) cap, and the deduction floor for charitable contributions.
Overall Itemized Deduction Limit (2/37 Rule)
Starting in 2026, the OBBBA introduces a new limitation that applies specifically to taxpayers in the 37% tax bracket. For 2026, this generally includes single filers earning more than $626,350 and married couples earning more than $751,600.
Commonly referred to as the 2/37 rule, this provision effectively limits the value of itemized deductions to 35 cents for every dollar deducted.
For example: A married couple in the top bracket claiming $100,000 in itemized deductions would receive a tax benefit of approximately $35,000 instead of $37,000.
While deductions still reduce taxable income, the benefit attached to each dollar is reduced at higher income levels.
State and Local Tax (SALT) Cap
The OBBBA retains the SALT deduction cap but increases it to $40,400 for 2026, with a 1% annual increase scheduled through 2029 before reverting to $10,000 in 2030.
However, this higher cap doesn’t apply uniformly. For higher-income taxpayers, the SALT deduction is reduced by 30% of the amount by which modified adjusted gross income (MAGI) exceeds a set threshold.
For 2026, that threshold begins around $500,000 (indexed annually), and as income increases, the allowable deduction declines.
For example:
- A taxpayer with $550,000 of income would see their SALT deduction reduced by approximately $15,000
- At income levels above roughly $600,000, the effective SALT cap can return close to the prior $10,000 limit
This is particularly relevant in higher-tax areas, where property and state taxes can quickly exceed these thresholds.
Charitable Contribution Deduction Floor
Charitable giving is also affected by a new deduction floor. Starting in 2026, charitable contributions are deductible only to the extent they exceed 0.5% of adjusted gross income (AGI).
For example: A household with $500,000 in AGI would not receive a deduction on the first $2,500 of charitable contributions.
This provision reduces the immediate tax benefit of smaller or consistent annual donations, particularly for higher-income households.
Taken together, these adjustments create a subtle but meaningful difference. The same financial inputs can now lead to higher tax results—not because rates increased, but because the mechanics surrounding those rates have changed.

Where Do Hidden Tax Increases Occur in 2026?
Hidden tax increases can occur primarily through bracket compression and uneven inflation adjustments, which can push more income into higher tax rates without a formal rate increase.
While tax brackets continue to adjust for inflation, those adjustments are not uniform. Lower brackets have received relatively larger adjustments, while the top brackets have increased more modestly. As a result, a greater portion of income can fall into the 37% bracket, even when earnings remain relatively stable.
For high-income households, this creates a measurable effect:
- The threshold for the top bracket may not rise enough to keep pace with income growth.
- A larger share of income is taxed at 37%.
- The 35% bracket effectively narrows, reducing the range where income is taxed at lower marginal rates.
This is what drives bracket compression. It’s not a rate increase, but it can lead to a higher overall tax bill because more income is exposed to the top rate.
How Does the AMT Affect High-Earners in 2026?
The Alternative Minimum Tax acts as a “shadow” system that often triggers higher liabilities during peak income years. While 2026 exemption levels remain relatively high—approximately $140,200 for joint filers and $90,100 for single filers—the way those exemptions phase out has become more restrictive.
The 2026 Phaseout Dynamic
Starting in 2026, the income range where AMT exemptions begin to phase out becomes more compressed. For married couples, this phaseout begins around $1,000,000 of AMT income (approximately $500,000 for individuals).
Within this range, the exemption is reduced more quickly as income rises. In practical terms, this means that for each additional dollar of income, a portion of the exemption is lost, increasing the amount of income subject to AMT.
Because exemption loss and tax liability occur simultaneously, effective tax rates within the phaseout range can increase significantly, particularly when income is concentrated in a single year.
High-Impact Scenarios
AMT exposure is especially sensitive to timing-related events:
- Incentive Stock Options (ISOs): The spread at exercise may be treated as income for AMT purposes
- Large capital gains: Concentrated gains can push income into the phaseout range
- SALT interaction: State and local taxes remain non-deductible under AMT, increasing the difference between systems
Rather than viewing AMT as a penalty, it is more useful to view it as a variable tied to income timing. Spreading income or transactions across multiple years may reduce the impact in any single period.
Jupiter’s Denver investment advisors can work with you to evaluate how these timing decisions interact with AMT and your overall tax exposure.

FAQs
Why could high-earners pay more in 2026 if tax rates stay the same?
High-earners may pay more because deductions can provide less benefit, more income may reach the top bracket, and AMT can apply more quickly. These factors change how income is taxed without increasing the headline rate.
How does AMT affect high-income households in 2026?
AMT becomes more relevant as income rises, particularly when income is concentrated in a single year. It can increase effective tax rates during certain income ranges.
What is a tax stress test in wealth management?
A tax stress test models how different scenarios affect tax results over multiple years. It helps identify how changes in income, timing, and market conditions influence overall outcomes.
