The exclusion of up to $500,000 of capital gains on the sale of a primary residence under IRC Section 121 is one of the most generous tax preferences available under the tax code, due in no small part to the fact that most people only have occasion to sell their home and harvest such gains a few times in a lifetime.
However, for those who also invest in rental real estate, the capital gains exclusion on the sale of a primary residence creates an appealing tax planning opportunity – to convert rental real estate into a primary residence, in an effort to take advantage of the capital gains exclusion to shelter all of the cumulative gains associated with the real estate. And since the Section 121 exclusion can be used as often as once every 2 years, the planning opportunity is quite significant for those with large rental real estate holdings (or simply those who serially purchase new primary residences!).
To prevent abuse of this planning scenario, Congress has enacted several changes to IRC Section 121 over the past 15 years, preventing depreciation recapture from being eligible for favorable treatment, requiring a longer holding period for rental property acquired in a 1031 exchange, and more recently forcing gains to be allocated between periods of “qualifying” and “nonqualifying” use. Nonetheless, some opportunities remain for real estate investors who do have the flexibility to change their primary residence in an effort to shelter capital gains on long-standing real estate properties.
