Are you planning to sell business property that has appreciated in value and then purchase like-kind property a short time later? The tax code provides special rules that allow you to defer the tax on the gain you realized as long as you meet certain requirements set forth in the rules for like-kind exchanges. These transactions are sometimes called tax-free transactions, but that term is inaccurate because you’re really deferring the gain on the sale of the first property into the property you acquired in the like-kind exchange. By deferring the gain, you don’t have to pay tax on the gain until you sell the new property.
For example, assume you own a building and sell it for a $1 million gain, and then buy another building for $3 million 60 days later. If you follow the rules for like-kind exchanges, you can defer the gain when you sell the first building by reducing your basis in the second building by $1 million, creating a $2 million basis in the newly acquired building.
The code allows for this tax deferral based on the position that by changing from one property to another, you are still in the same economic position. Basically you defer the tax until you sell the second property.
However, there are still some formalities that need to be met, so it’s important to meet with your tax professional to be certain that the transaction is set up properly.
