I have an S Corporation with a vehicle that was placed in service 5 years ago. It was converted to personal use in early 2014.

But it was only 50% business business over that 5 year period.

Let's say it was purchased for $40,000, and 179 of $20,000 was taken.

Now, at conversion, the FMV is $20,000.

My software is showing $20,000 of basis ($40K cost, less $20K 179), despite the 50% business use clearly reported on the return.

I think my basis should be $0 (cost of 50% of $40K = $20K, less $20Kk 179).

And my proceeds should be 50% of the $20K total, and thus I should have a $10K gain, subject to 179 recapture.

I'll take the steps to manipulate the return to return that result - $10K of gain, but I wanted to make sure I'm not missing something - do I somehow get the benefit of the personal basis of the vehicle in determining gain? (No way that's right). Thoughts?

I think my basis should be $0 (cost of 50% of $40K = $20K, less $20Kk 179).======>>>Then $8K; you ned to take sec 179first; and then 50% bonus depreciation; $40K-$20K(sec 179) and then 50%*$20K=$10K;$20K-$10K=$10K.And 20%*$10K=$2K, so $10K-$2K=$8K.

And my proceeds should be 50% of the $20K total, and thus I should have a $10K gain, subject to 179 recapture.

Then, have the S corp reimburse you using either the mileage rate or actual expenses (including depreciation and ;section 179 expensing) methods discussed above.the bottom line;as you used your car fro biz purposes, 50%, then when you dispose of it, and there is gain ,sec 1231 gain, ltcg I mean, then you also must recapture sec 1245 gain taxed as ordinary income at 25% aslongas your marginal tax rate is 25% or higher.
