When I look at the federal worksheets supporting the forms, it shows one form for depreciable property, and another for depreciable property as adjusted for AMT. On the first one, it reflects the number I put in, of actual depreciation ($8830). On the one adjusted for AMT, it shows the number of "allowable" depreciation, what I should have taken ($20K+) Then, the AMT is added to the 1040 to raise my federal taxes and lower my refund. That's what I mean when I say that there is no adjustment on my federal return whether I input $8830 or the $20K+ number. The return basically ignores my $8830 number, and just automatically puts in the $20K+ number and adjusts it through application of the AMT.
But there is a difference for my state return. If I put in the 8830 number, I get a higher state refund (reflecting the lower depreciation I really took). If I put in the 20K number, I get a lower return (reflecting the higher depreciation I could have, but did not take). Can anyone think of any reason why the AMT adjusted number would be used on the Fed return, but not taken over to the State return? Does California not follow the Fed AMT rules? California also has a depreciable property worksheet, and a "depreciable property as adjusted for AMT" worksheet, but the California one does not automatically put in the 20K number for previous depreciation, it is just blank. Basically, does anyone know whether California (or any other state) follows the same rules as the Feds in recapturing "allowable" depreciation as opposed to actual depreciation taken? Believe me, I know this is confusing, I appreciate anyone who is actually looking at it and taking a second to think about it!
