Check out Nevada and Wyoming, they provide a level of anonymity for members/managers which is what I believe you are seeking. I'm not, however, positive about what you mean by "registering". There are also many nations in the Caribbean (and elsewhere in the world) which allow equity holders to remain anonymous to certain degrees. Any of the foregoing won't change your requirement to remit taxes to the IRS and to any state to which they may be due.
