Thanks. Would I need to have a service agreement with my sons and be paying them?
Or would us producing videos together which generate income be sufficient?
If you are producing video together for profit, then you and your sons are engaged in a general partnership, which is reported on IRS Form 1065. It's always a good idea to have a written agreement -- not for the IRS, but because where money is involved, ambiguity leads to disputes. You don't have to use a partnership. You can employee your sons, or hire them as independent contractors, or partner with them -- or, create a corporation or LLC and distribute shares. Hope this helps.
