In
the past ten years there have been eight temporary legislative AMT-related
"patches," designed to forestall a sudden dramatic increase in the number of
individuals who are affected by the AMT. The latest two-year patch, included as
part of the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation
Act of 2010, is effective through December 31, 2011. That means you can expect
additional AMT legislation later this year or in early 2012.
What is the AMT?
The
AMT is essentially a separate federal income tax system with its own tax rates,
and its own set of rules governing the recognition and timing of income and
expenses. If you're subject to the AMT, you have to calculate your taxes
twice--once under the regular tax system and again under the AMT system. If your
income tax liability under the AMT is greater than your liability under the
regular tax system, the difference is reported as an additional tax on your
federal income tax return. If you're subject to the AMT in one year, you may be
entitled to a credit that can be applied against regular tax liability in future
years.
How do you know if you're subject to the AMT?
Part
of the problem with the AMT is that, without doing some calculations, there's no
easy way to determine whether or not you're subject to the tax. Key AMT
"triggers" include the number of personal exemptions you claim, your
miscellaneous itemized deductions, and your state and local tax deductions. So,
for example, if you have a large family and live in a high-tax state, there's a
good possibility you might have to contend with the AMT. IRS Form 1040
instructions include a worksheet that may help you determine whether you're
subject to the AMT (an electronic version of this worksheet is also available on
the IRS website), but you might need to complete IRS Form 6251 to know for
sure.
Common AMT adjustments
It's
no easy task to calculate the AMT, in part because of the number and seemingly
disparate nature of the adjustments that need to be made. Here are some of the
more common AMT adjustments:
- Standard deduction and personal exemptions: The federal standard deduction, generally available under the regular tax system if you don't itemize deductions, is not allowed for purposes of calculating the AMT. Nor can you take a deduction for personal exemptions.
- Itemized deductions: Under the AMT calculation, no deduction is allowed for state and local taxes paid, or for certain miscellaneous itemized deductions. Your deduction for medical expenses may also be reduced, and you can only deduct qualifying residence interest (e.g., mortgage or home equity loan interest) to the extent the loan proceeds are used to purchase, construct, or improve a principal residence.
- Exercise of incentive stock options (ISOs): Under the regular tax system, tax is generally deferred until you sell the acquired stock. But for AMT purposes, when you exercise an ISO, income is generally recognized to the extent that the fair market value of the acquired shares exceeds the option price. This means that a significant ISO exercise in a year can trigger AMT liability. If ISOs are exercised and sold in the same year, however, no AMT adjustment is needed, since any income would be recognized for regular tax purposes as well.
- Depreciation: If you're depreciating assets (for example, if you're a sole proprietor and own an asset for business use), you'll have to calculate depreciation twice--once under regular income tax rules and once under AMT rules.
AMT exemption amounts
While
the AMT takes away personal exemptions and a number of deductions, it provides
specific AMT exemptions. The amount of AMT exemption that you're entitled to
depends on your filing status.
AMT Exemption Amounts by Filing Status | 2011 | 2012 |
---|---|---|
Married filing jointly | $74,450 | $45,000 |
Single or head of household | $48,450 | $33,750 |
Married filing separately | $37,225 | $22,500 |
Note: The 2012 figures assume no additional
Congressional action.
Your
exemption amount, however, begins to phase out once your taxable income exceeds
a certain threshold ($150,000 for married individuals filing jointly, $112,500
for single individuals, and $75,000 for married individuals filing
separately).
What happens in 2012?
AMT
exemption amounts and phaseout thresholds are not adjusted for inflation--they
only change through legislation. This is one of the principal reasons that more
people tend to be subject to the AMT each year. The increased AMT exemption
amounts included in the Tax Relief, Unemployment Insurance Reauthorization, and
Job Creation Act of 2010 are for the 2010 and 2011 tax years only. Unless
Congress passes new legislation, 2012 AMT exemption amounts will return to
pre-2001 levels. In addition, without new legislation, the AMT rules could limit
your ability to claim certain nonrefundable personal tax credits in 2012,
including the American Opportunity (Hope) and Lifetime Learning tax credits, the
dependent care credit, and the credit for the elderly and disabled.
AMT rates
Under
the AMT, the first $175,000 of your taxable income is taxed at a rate of 26%.
(If your filing status is married filing separately, the 26% rate applies to
your first $87,500 in taxable income.) Taxable income above this amount is taxed
at a flat rate of 28%.
The
lower maximum tax rates that apply to long-term capital gain and qualifying
dividends apply to the AMT calculation as well. So, even under AMT rules, a
maximum rate of 15% (0% for individuals in the lower two tax brackets) applies.
However, long-term capital gain and qualifying dividends are included when you
determine your taxable income under the AMT system. That means large capital
gains and qualifying dividends can push you into the phaseout range for AMT
exemptions, and can indirectly increase AMT exposure.
Technical Note: In the context of AMT exemption
amounts and tax rates, taxable income really refers to your alternative minimum
taxable income (AMTI). Your AMTI is your regular taxable income increased or
decreased by AMT preferences and adjustments.
Summing up
Owing
AMT isn't the end of the world, but it can be a very unpleasant surprise. It
also turns a number of traditional tax planning strategies (e.g., accelerating
deductions) on their heads, so it's a good idea to factor in the AMT before the
end of the year, while there's still time to plan.
If
you think you might be subject to the AMT, it may be worth sitting down to
discuss your situation with a tax professional.
