The Alternative Minimum Tax – The Rules and the Impact

by Vanessa J. Duchman And Steve E. Shane

It began in 1969 with a mere 155 taxpayers. Now it is estimated that the Alternative Minimum Tax (AMT) will affect over 50 million taxpayers by the year 2015.

In 1966, those 155 taxpayers paid no tax on income exceeding $200,000 (estimated to be $1.2 million in today’s dollars). When Congress discovered the loophole in 1969, the Alternative Minimum Tax was born. While the initial intent of the AMT was to prevent those few high-income taxpayers from utilizing deductions that reduced their taxable income, the once obscure AMT now impacts more taxpayers than was ever originally contemplated.

The multitude of financial firms publishing articles on the topic have provided varying figures as to the number of taxpayers and income ranges that will be affected by the AMT over the next several years. Regardless of the exact numbers, it is certain that with each passing tax year, an ever-increasing number of taxpayers will be subject to the AMT, particularly:

The growth of AMT taxpayers is due to certain “preference items” such as state and local income taxes, real estate property taxes, and personal exemptions that get added back to taxable income in order to calculate the AMT.

While the AMT rules permit an exemption of up to $58,000 for married individuals filing jointly, this exemption is phased out at a $150,000 income threshold.

Unfortunately, this threshold is not slated to adjust for inflation as the regular tax rules allow. The so-called “bracket creep” is the main reason the AMT has begun to have a greater impact. Investors incurring significant capital gains in a particular year – or – employees exercising large amounts of incentive stock options rapidly approach the phase-out threshold of $150,000 because these amounts are included in their regular income. As a result, they lose the ability to use their exemption, further increasing their AMT liability. Unless the rules are changed, the opportunities to avoid the AMT are limited. Taxpayers subject to the AMT generally seek to accelerate ordinary income into the current year and defer those deductions that are not allowable for AMT purposes.

Consider the following strategies to reduce your AMT liability:

If you live in a high income tax state, take advantage of pre-tax retirement plan contributions because they reduce taxable income, and, therefore, state income tax.

NOTE: Before implementing any of these strategies, you should discuss them with your professional tax advisor to identify potentially negative consequences in other areas of your financial life.
