At some point, business owners need to sell or otherwise dispose of business assets. It may be a computer or vehicle or real property that your business owns and no longer uses or needs. You will have to report any gain or loss you make on the sale to the IRS. There are special rules that apply to the sale of business property which allow more favorable tax treatment for gains and losses. However, whether you'll be able to take advantage of the lower tax rates will depend in part on the depreciation deductions you have taken on the property while you owned it.
You'll want to have a basic understanding of the tax rates and depreciation recapture rules that apply before you sell any business property.
