What are the different ways to add a member to an LLC?

Question

I have a Texas LLC. LLC is a partnership for federal tax purposes. There are 2 members at this time - let's say member A & B. B wants to leave and a new potential member (C) wants to join. C will join before B leaves (to preserve partnership status with IRS). I know that C can purchase an interest in the LLC, but are there other ways that C can be a member? I have done a little research and it appears that the LLC can give C an interest (capital and P&L) through perhaps a "gift" or goodwill entry. Are there any other ways that C can become a member? The primary concern is the federal tax implications for the method used to add C as a member. Adding a new member is not an issue for Texas purposes.

Answer 1

Usually a partner contributes money or property in exchange for a partnership interest.

However, a partner can acquire an interest in partnership capital or profits as compensation for services performed or to be performed.

Answer 2

In the case you describe, I think C should just buy Bs interest and the LLC would just change ownership names.
