What is AMT?
The Alternative Minimum Tax (AMT) is a near flat tax rate imposed on individuals, corporations, estates, and trusts. Getting taxed under AMT usually requires fairly high income levels. The end result ensures that most high income earners have to pay some income tax. Although the AMT exemption amount is not adjusted to inflation, it is usually “patched” by congress at the end of each year with legislation.
The IRS is currently tentatively waiting for congress to pass the 2013 patch. A patch before year-end could be implemented with minimal delays to most taxpayers. A patch after year-end, according to IRS Commissioner Steven Miller, could have serious repercussions for tax payers. The IRS would have to instruct over 60 million taxpayers that they can’t file or process their tax return until system changes are done.
