I guess it depends on the specifics, but the AMT Patch, as they call it, manages to exempt most upper middle class people. But yea, you can still get tripped up if you have, say, $150k income, high property and state income taxes, and 6 kids. You may well wind up having to pay 10% or so in federal income taxes.
Dude, you really don't know what the heck you are talking about.
Seems to me that if you make $150k, then write off $50k (or split it with tax credits for the kids), that you wind up paying $17k in federal income tax, which is about 11%.
Seems to me that you should get a better accountant for next year.
