- Legal vs tax
- State series statutes do not automatically create separate taxpayers. IRS and other states may treat series differently.
- Liability
- Internal walls only work if the formation state supports them and you actually segregate assets, accounts, and contracts.
- Default federal tax
- disregarded
- Other federal options
- partnership, s corporation, c corporation
- Formation / maintenance
- High. Do not use a series LLC as a cheap substitute for holding/operating companies without counsel.
- Public-record notes
- Series records may be less visible in some states and more confusing in others. Confusion is not a privacy strategy.
- Succession
- Each series needs its own ownership and transfer design.
- Investor fit
- Usually a red flag for outside investors and lenders.
Disqualifiers
- Need clean foreign qualification
- Need conventional venture documents
