The Alternative Minimum Tax, often called the AMT, was created to make sure certain high-income taxpayers could not use deductions, exclusions, and tax preferences to reduce their federal income tax too far.
Today, fewer taxpayers owe the AMT than in past decades, but it has not disappeared. Certain income levels, deductions, incentive stock options, capital gains, or other tax items may still cause AMT exposure.
At True North Wealth Management, we believe tax-aware planning can help clients avoid surprises and make more informed decisions about investments, income, retirement, and wealth transfer.
What Is the Alternative Minimum Tax?
The AMT is a parallel tax system.
In simple terms, taxpayers may need to calculate their tax liability under the regular income tax system and then again under AMT rules. If the AMT calculation produces a higher tax amount, the taxpayer may owe the difference.
The AMT uses a different set of rules for income, deductions, exemptions, and preference items. Some deductions that help under the regular tax system may be limited or unavailable under AMT.
The IRS provides Form 6251, Alternative Minimum Tax—Individuals, to help determine whether a taxpayer owes AMT.
Why the AMT Matters
The AMT originally targeted very high-income taxpayers, but for many years it affected more households than intended because the exemption amounts were not indexed for inflation until 2013.
The Tax Cuts and Jobs Act of 2017 significantly reduced the number of taxpayers subject to the AMT by increasing exemption amounts and phaseout thresholds. The Tax Policy Center estimates that the number of AMT taxpayers fell sharply after the TCJA and remained roughly around 200,000 through 2025.
Even so, taxpayers with certain income patterns or tax preference items should still pay attention.
2026 AMT Exemption Amounts
For tax year 2026, the IRS lists the AMT exemption amount as $90,100 for unmarried individuals and $140,200 for married couples filing jointly. The exemption begins to phase out at $500,000 for unmarried individuals and $1,000,000 for married couples filing jointly.
These thresholds can change, so taxpayers should review current IRS guidance or work with a qualified tax professional before making major tax decisions.
Who May Be More Likely to Owe AMT?
AMT exposure can depend on many factors. You may want to review your situation carefully if you:
Have high income
Exercise incentive stock options
Have large capital gains
Claim significant deductions affected by AMT rules
Own a business or partnership interest with AMT adjustments
Have private activity bond interest
Experience a major liquidity event
Have unusually high income in one year
Receive large bonuses or equity compensation
The AMT calculation can be complex, and many taxpayers only discover the issue when preparing their return.
AMT and Investment Planning
Investment decisions can affect AMT exposure.
For example, large capital gains may increase income enough to reduce or eliminate the AMT exemption. Certain tax-exempt bonds, such as private activity bonds, may also create AMT considerations. Incentive stock options can create AMT income even if the taxpayer has not sold the stock.
That is why tax planning should happen before major transactions when possible.
At TNWM, we help clients coordinate investment decisions with tax-aware planning so they can understand the possible impact before they sell assets, exercise options, rebalance portfolios, or create retirement income.
Form 6251: How You Know
The only way to know whether you owe AMT is to complete the AMT calculation, typically using tax software or by working with a tax professional.
Form 6251 helps taxpayers determine whether AMT applies. If the IRS later determines that AMT should have been paid, the taxpayer may owe back taxes, interest, and potentially penalties.
If your income or deductions changed significantly this year, it may be worth reviewing your exposure before tax filing season.
Planning Ideas to Discuss With a Tax Professional
AMT planning is highly individual. Depending on your situation, a tax professional may review:
Timing of income
Timing of deductions
Capital gain realization
Tax-loss harvesting
Incentive stock option exercise timing
Charitable giving strategy
Retirement contributions
Roth conversion timing
Estimated tax payments
Private activity bond exposure
State and local tax deductions
Business income or partnership items
Not every strategy helps every taxpayer. Some steps that reduce regular tax may not reduce AMT, and some actions may increase AMT unexpectedly.
Where Federal Tax Dollars Go
Many taxpayers wonder where federal revenue is spent. The Congressional Budget Office reports that in fiscal year 2024, major federal outlay categories included Social Security, Medicare, Medicaid and other health programs, net interest, defense, income security programs, and other government activities. The CBO’s March 2025 budget data provides a detailed breakdown of federal revenues and spending.
While understanding federal spending does not change your tax liability, it can provide helpful context for broader tax policy discussions.
Avoid AMT Surprises
The Alternative Minimum Tax may affect fewer taxpayers than it once did, but it remains important for certain high-income households, investors, business owners, and taxpayers with complex income.
If you are facing a major tax year, large investment sale, equity compensation event, business income change, or retirement income transition, schedule a conversation with True North Wealth Management.
A thoughtful review can help you coordinate with your tax professional, understand potential AMT exposure, and make more informed decisions before tax season arrives.
