How do I determine if sale proceeds from an asset are taxable?
If it's fully expensed, it has zero basis. Any sale is taxable, 100%. To the ordinary income / cap gain issue raised in comment - It's a cap gain, but I believe, as with real estate, special rates apply. This is where I am out of my area of expertise, and as they say - "Consult a professional."
