I have paid it twice in a 11 year period as an attending.
Mainly avoided it by moving to no state income tax state Florida.
If you make more than $150-200k. And have big deductions like personal property taxes and or state income tax reductions. And claim 2 or more kids.
Ur chances of being in the AMT are close to 90%
I have seen people making as little as 90k with 5 kids and high property tax state like New Jersey get hit with AMT.
