Article Highlights Alternative Minimum Tax Deterrent to Tax Shelters Tax Reform Changes Tax Deductions and Preferences Incentive Stock Options Tax Planning Opportunity Although Congress, as part of the recent tax reform, promised to do away with the alternative minimum tax (AMT), it only did so for C corporations; as a result, the AMT still applies to individuals. Congress originally developed the AMT in 1969 as a means to prevent high-income individuals from using tax shelters to reduce their taxes. For the AMT, federal income tax is calculated without certain deductions and tax preferences. This tax applies if it is greater than the regularly computed income tax. Although it has since been indexed to inflation, the AMT at one point began to apply to middle-income taxpayers, who are not the intended targets of this punitive tax. The AMT computation includes a tax-exempt amount, but this amount begins to phase out for taxpayers whose adjusted gross income (AGI) exceeds a certain threshold (depending on their filing status). Although the tax reform did not eliminate the AMT, it did mute that tax considerably by increasing the AMT exemptions and by substantially raising the exemption-phaseout thresholds, as illustrated below. The exemptions and AGI phaseout thresholds will be inflation-adjusted in future years. AMT EXEMPTIONS ($) Status 2017 2018 Married Filing Jointly or Surviving Spouse 84,500 109,400 Single or Head of Household 54,300 70,300 Married Filing Separately 42,250 54,700 EXEMPTION-PHASEOUT AGI THESHOLDS Status 2017 2018 Married Filing Jointly or Surviving Spouse 160,900 1,000,000 Single or Head of Household 120,700 500,000 Married Filing Separately 80,450 500,000 These are the tax deductions and preferences that most often affect the average taxpayer: Some itemized deductions are allowed for the regular tax computation but not for the AMT computation. Tier II miscellaneous itemized tax deductions are not allowed for the AMT computation; in addition, for the years 2018 through 2025, they are also not allowed for the regular tax computation. This category primarily includes employee business expenses, investment expenses, and legal fees. As these expenses aren’t currently deductible in either tax calculation, there is no adjustment for the AMT calculation. The AMT computation does not allow the itemized deduction for interest on home-equity debt; such debt also is not deductible in the regular computation through 2025, which eliminates another difference in the two computations. Employee incentive stock option tax preferences are also handled differently in the two computations, as is discussed in more detail later in the post.

2026 IRS Mileage Rates: Key Updates and Insights
The IRS has rolled out the inflation-adjusted mileage rates for 2026, offering taxpayers an efficient way to claim deductions for vehicle-related expenses incurred for business, charity, medical, or moving purposes. These adjustments reflect the continued economic shifts impacting car operation costs.
Effective January 1, 2026, the new standard mileage rates are established as follows:
- Business Travel: Increased to 72.5 cents per mile, inclusive of a 35-cent-per-mile depreciation allocation. This marks a rise from the 70 cents per mile rate set for 2025
- Medical/Moving Purposes: Reduced slightly to 20.5 cents per mile, down from 21 cents in the previous year, reflecting the variable cost considerations.
- Charitable Contributions: Consistent at 14 cents per mile, a fixed rate unchanged for over a quarter-century.
As is typical, the business mileage rate considers the integral fixed and variable costs of automobile operation. Meanwhile, the medical and moving rates remain contingent on variable expenses as determined by the IRS study.

It is critical to note that the One Big Beautiful Bill Act (OBBBA) held firm on disallowing moving expense deductions except for specific cases within the Armed Forces and intelligence community, marking a substantial shift since 2017.
When engaging in charitable work, taxpayers might opt for a direct expense deduction over the per-mile method, covering gas and oil costs. However, comprehensive upkeep and insurance costs are non-deductible expenses.
Business Vehicle Use Considerations: Taxpayers can alternatively compute vehicle expenses using actual costs, which might benefit from shifting depreciation rules, particularly through bonuses and first-year advantages. Keep in mind, however, reverting from actual cost calculations to standard rates in subsequent years is restricted, particularly per vehicle protocol and when exceeding four vehicles in concurrent use.

Additionally, parking, tolls, and property taxes attributable to business can be deducted independently of the general rate, an often-overlooked advantage by many business owners.
Tax Strategies for Employers and Employees: Reimbursements based on the standard mileage framework, providing the right documentation is in place, remain tax-free for employees. Meanwhile, the elimination and continued prohibition of unreimbursed employee deductions continue, with particular exceptions offered to qualified personnel across specific occupations.
Opportunities for Self-employed Individuals: Entrepreneurs remain eligible for deductions on business-related vehicle use via Schedule C, with potential to account for business-use interest on auto loans.

Heavy SUVs and Deduction Advantages: Heavier vehicles exceeding 6,000 pounds but under 14,000 pounds open opportunities for substantial tax deductions through Section 179 and bonus depreciation avenues. The lifecycle of such a vehicle bears implications on recapturing initially claimed deductions, urging cautious tax planning.
