TIC's are more complicated, but someone in the domain business could model it after the real estate business. A sponsor could buy a premium domain with a business plan to develop it and then sell fractional intest to investors who wanted to roll their equity tax free from the sale of their own domains. The sponsor takes a management fee and the investors own an undivided interest in the business and recieve their pro rata share of the profits and ultimate sale.
I understand TIC's would be a bit more comlicated, but why is no one using 1031 exchanges to defer payiing capital gains taxes?
