Wall Street may have to come up with a new strategy to replace a type of deal that has been popular among activist investors and companies.

On Thursday, the House of Representatives approved legislation including provisions that would remove the tax advantages of spinning off corporate real estate into a separate, publicly traded real estate investment trust. The end of such tax-free spinoffs will generate $1.9 billion in additional tax revenue in the coming years, the Joint Committee on Taxation has estimated.

Hilton Worldwide may end up being the last big company to reap the benefits of this type of deal. The company, which the Blackstone Group took public about two years ago, is working on a plan to spin off its hotels into a REIT, according to a person briefed on the matter. The hotel operator has requested that the Internal Revenue Service deem the transaction tax-free.

These spinoffs have been a popular tactic of activist investors who have pushed companies to unlock cash by separating themselves from their real estate holdings.
