AMT seems to be miscalculated by TurboTax2006.

Feb 07, 2008 2 Replies

In my investigation of my 2006 return's calculation of my AMT by Turbotax 2006, two spurious addendas to AMT income appear; 6251 line 6, a minus 4417 (via form 1040A itemized) and a "post 1986 depreciation (AMT difference)" of another minus 2747.



But these were added as plus amounts, increasing the amount of AMT income. The 6251 line 28 sum shown by turbotax shows an incorrect sum; it mathces neither the implied sum (minuses obeyed), nor the gross sum, and is more than the gross minus's doubled.



What is going on?



Am I due a refund?

Just one suggestion - make sure you did not leave "overrides" anywhere on TT. I don't have the internal math to TT but it apparently assumes the worst case for any override number. TT wants you to anter those numbers into the supporting schedules, requiring the user to conform. (Why, I do not know.) As far as plugging your numbers into TT to duplicate your reported errors, well .... Try contacting TT with your question, if the above doesn't handle it.

As "official" as that cockamamie form is, it is convoluted beyond belief. In reality, it subjects the entire tax return to a series of tests, all outside the basic 6251 form. After all those tests, it selects a delimiter (via convoluted logic) as the chosen AMT determinant.

I followed that trail to the bitter end, and I find my original return to be according to THEIR liking.

Job security for the IRS and Coongressmen, I say.
