Just look at it this way. AMT is for rich people only. They make lots of money, and the government makes sure they pay more in taxes by AMT.
Adjustments: a good way to memorize adjustments for AMT.
Government: HEY RICH GUYS, SINCE YOU GUYS ARE RICH, NO PERSONAL EXEMPTIONS AND STANDARD DEDUCTIONS FOR YOU ALL!! OH, AND THOSE EXPENSES YOU THOUGH YOU COULD DEDUCT ABOVE 2% AGI – NOT DEDUCTIBLE!!
Rich guys: What? Why? *Waaaa waaa* *Not fair*
Government: SORRY, FOLKS. BUT HEY, WE'LL GIVE YOU GUYS A BREAK ON YOUR MORTGAGE INTEREST IF IT'S USED FOR BUILDING, REPAIRING YOUR HOUSE….BUT IF YOU GUYS USE THE LOAN TO BUY A CAR, CUZ YOU'RE ALL SOOOOOOO HOT AND ALL, THEN NO. YOUR INTEREST ON THE LOAN (backed by the house) FOR THAT SUPER COOL CAR (also known as home equity loan) IS NOT DEDUCTIBLE.
Rich guys: Why! Oh, god, why! I love cars!
Government: OH YEAH? ALSO…YOU GUYS OWN FACTORIES AND WANNA AMORTIZE YOUR EQUIPMENT SO FAST? HAHA! GUESS WHAT! ONLY AT 150%! SO ADD PART OF THAT AMORTIZATION BACK, SUCKAS!!
Rich guys: I hate you!! I hate you!!
Preferences:
Easy: Just add the interest-exempt interest. (most likely tested on this)
Percentage Depletion / Excess intangible drilling costs (IDC) (slim chance on test)
Depreciation (ACRS/MACRS) (slim chance on test)
You need to know the exemption formula. It's very easy.
And the carry-over of AMT…how it works.
