With the IRS issuing investor-friendly draft regulations for the new Opportunity Zone (OZ) tax incentive program, investments in OZ investment funds will likely accelerate. Before they do, state lawmakers should change their personal and corporate income tax laws so their states don’t provide tax breaks on top of the new federal tax breaks. If states don’t “decouple,” they’ll forgo revenue needed to fund education, health care, roads, and other critical building blocks of robust, inclusive economies to subsidize investments that will often occur in out-of-state OZs.
