Actually, there a lot of things to consider, for example:
1) You indicated that you will be raising funds internally. This is never as clear cut as you stated in this post as I would presume "internally" doesnt necessarily mean the investment manager is the only one supplied money. Nevertheless you will need to comply with SEC regulations and determine if the fund will be a 3(c)(1) or a 3(c)(7) fund. You will also need to comply with all applicable US State securities regulations (Blue Sky).)
2) You will also have other tax issues that will likely arise with the jurisdiction of the formation of the LLC and how you expect to fund the carry.
I would recommend that you discuss all of the tax and regulatory implications with a qualified attorney prior to proceeding to ensure all "i"s are dotted and "t"s crossed. Please also freel free to contact me off this board if you have additional questions at:
