I'd bet Jeff-Ohio does know, despite his saying he doesn't. I'd also bet he's at least passingly familiar with the section that answers the basis question. Its number is 362.
And for good measure, let's walk through an example.
Cost basis to owner before capital contribution is $500.
Adjusted basis before capital contribution is $300.
FMV of computer at time of capital contribution is $100.
Add this assumed fact: S corp. sells the computer one month later for $150.
Now change to this assumption: S corp sells computer one month later for $50.
For simplification, don't worry about whether depreciation is or even can be claimed for the month S corp. owned computer.
What is tax gain or loss amount and nature, and while we are at it, answer Spell's question.
