Have you run the numbers w/ different state witholding numbers (itemized deductions)? Last year I was able to, barely, avoid AMT by stopping our state withholdings. I did a tax projection in November. Unfortunately, we will probably fall into it this year unless our fearless leaders change the code
Our state doesn't not enforce underpayment penalties so it worked to our favor. I may do the same this year and will decide towards the fall (our income varies b/c of husband's S corp income).
Hope this gives you an idea.
