What you can expect are not necessarily updates to the legislation itself, but updates to enforcement. The Biden Administration's tax platform addresses OZ reporting and monitoring, and it's likely a Biden Treasury Department will conduct studies about how much impact OZ projects are having. If you're interested in making the most impact, search the Internet for impact investing in OZs, and you should be able to find some good options. Another good source would be looking up the CDFIs that are getting involved in the program. One fund I'm aware of that is doing very good work in the impact investing area is the River Fund.
