What is the Alternative Minimum Tax (AMT) and Do I Have to Pay It?

As the name says, it’s an “alternative” tax. It’s calculated at the same time as your regular taxes. If the alternate method results in a higher tax, the difference between it and your regular tax is the AMT tax - the extra tax you'll pay.  

TurboTax will calculate this tax as you’re doing your taxes and let you know if you owe this tax. If you have the AMT tax, it will be on your Form 1040, line 45. Your return will also include Form 6251 that shows the calculations for your AMT tax. 

The AMT was conceived in 1969 as an alternative tax to ensure that the wealthiest taxpayers, even with their big deductions and loopholes, didn't avoid paying income taxes. However, because the tax was not adjusted for inflation, over the years the AMT began to reach down into the middle class. 

How do I know if I will be hit with the AMT?

Unfortunately, there are no definite ways for avoiding the AMT. It's determined by multiple factors, but most likely you won’t be affected.

If you would like a heads-up before you file, we can help. TurboTax offers a quick and easy way to learn if you'll be affected by the AMT using our free tax calculator, TaxCaster2015.  It estimates what your 2015 taxes are likely to be, whether you will owe AMT and if so, how much.

Who is most at risk for the AMT?

Taxpayers, who have higher than average incomes, are married and have more than two children, own a home and live in a state with high incomes taxes, such as California, New York and Michigan, may be subject to AMT tax.

The AMT affects such taxpayers because it won't let them count certain deductions that would otherwise lower their taxes, such as dependents or children, state income taxes, property taxes, interest on second mortgages or home-equity loans and high medical expenses.


How can I avoid it?

Most people affected by it can’t get around it. The AMT was designed to limit or close loopholes – so it's very difficult to avoid.

For an in-depth understanding of the AMT, see IRS Tax Topic 556.

What is the AMT exemption?

For tax returns not affected by the AMT, you are allowed to claim certain tax breaks that reduce your taxable income and taxes owed.

With the AMT, these benefits are reduced or eliminated. You do get a deduction known as an AMT exemption.

The exemption amounts for 2015 are $53,600 for individual taxpayers, $83,400 for married taxpayers filing jointly and surviving spouses, and $41,700 for married persons filing separately.
