starting to work with another realtor,
This sounds like the start of a partnership to me. If this will continue to "grow" as a partnership I would highly suggest seeking the services of a CPA. Especially if the state of either partner taxes personal income. A partnership generally files a 1065 Partnership return. When you have a business owned by 2 or more persons, then treating it as and filing it as a partnership can usually make things easier and simpler on the tax front. But you should seek the advice of a CPA or other tax professional in your locale on this since you can share more detailed information about your setup in person, than you might be willing to share in this public user-to-user forum.
