Corporations who gross less than 7.5 million for three consecutive years are exempt, but only so long as they continue to follow the same guidelines. When computing Alternative Minimum Tax, certain deductions are prohibited, such as employees’ personal expenses and fees for services used in preparation for filing taxes. In addition, home mortgage interest deduction can only pertain to the owner’s primary and secondary residences. One large difference between the regular system and Alternative Minimum Tax is that in the latter, if medical expenses go over 10%, they can be deducted, whereas with the regular system, they only need to exceed 7.5%.

The Alternative Minimum Tax has negative effects on those living abroad, because it disallows a portion of foreign tax credit, causing millions of people who are living outside of the United States of America to be taxed double. To determine whether or not someone owes the Alternative Minimum Tax, it takes a lot of work reading over complex instructions and filling out long worksheets and forms. The simplest way of getting out of having to pay the Alternative Minimum Tax would be to raise your regular tax, and exempt yourself from any liability, but who wants to pay even more taxes? Possibly the most effective way of avoiding the Alternative Minimum Tax is by making less than 150,000, or more than 415,000 per year. Many people see significant flaws within this system and would like to see it changed, if not repealed. The most common suggestion is that it should be amended to have less of an effect on those with lower incomes.

The Difference between Alternative Minimum Tax and Regular Tax

The AMT has a completely different set of calculations than the regular tax. When calculating regular tax, you add up your total income, subtract various deductions and personal exemptions, and then calculate the tax. With the regular tax, you can also claim various credits to reduce your tax even further. AMT rates start at 26% and move to 28% at higher income levels while regular tax rates start at 10% and then move through a series of steps to a high of 35%.

The AMT, however, does not allow the standard deduction, personal exemptions, or certain itemized deductions. Also, some income which is not subject to the regular tax is added for AMT purposes. Your tax under AMT rules may therefore be higher than what you would owe under regular taxation rules. The AMT determines the minimum amount of tax someone with a specific income should pay. If this person is paying that much already with regular income tax, he or she will not be subject to paying AMT. If, however, that taxpayer’s regular tax falls below the minimum, he or she has to make up the difference by paying the alternative minimum tax.

Determining How Much AMT to Pay

After calculating your taxes using both methods, you will need to compare the amount you need to pay according to regular income tax and the amount according to the AMT. If the regular tax amount is higher, then you are not liable to pay any AMT. However if the regular tax is lower, then the difference between the two amounts will be the AMT you will have to pay.

On a more positive note, an AMT credit can also reduce your taxes in years after the year you paid the alternative minimum tax. This is applicable if you paid AMT because of certain “timing items” such as exercising incentive stock options.
