In essence, the intention of the AMT is to set a minimum tax rate of about 27% on the highest earning tax payers so that they can not use loop holes or other tax reduction strategies to entirely avoid paying a substantial amount of income tax. The AMT affects taxpayers who have what are known as "tax preference items." These include (among others) long term capital gains, accelerated depreciation, percentage depletion, and certain tax-exempt income, which are all considered to have favorable tax treatment and could trigger the alternative minimum tax. Numerous tax credits can also trigger the AMT.
In a brief issued by the Congressional Budget Office (No. 4, April 15, 2004), the conclusion was clear:
- Over the coming decade, a growing number of taxpayers will become liable for the AMT. In 2010, if nothing is changed, one in five taxpayers will have AMT liability and nearly every married taxpayer with income between $100,000 and $500,000 will owe the alternative tax. Rather than affecting only high-income taxpayers who would otherwise pay no tax, the AMT has extended its reach to many upper-middle-income households. As an increasing number of taxpayers incur the AMT, pressures to reduce or eliminate the tax are likely to grow.
Nobody is really addressing this in politics, probably because if it was repealed in full there would be a huge loss in gov't money, and if they try to reform it, they get the standard "tax the successful" line. What are your thoughts?
