Series LLC Business type


A series LLC is a group of LLCs which are owned in a tiered-down structure. The top tier LLC owns the lower-tiered LLCs.

Each LLC has assets separate from the others, while the main LLC controls all the LLCs in the series. Each unit has its own owners (members) and is liable only for its own debts and obligations.

Registered with SOS

If the series LLC is registered in California, the first LLC in the series uses the SOS number as the identification number on its initial payment voucher. All other LLCs in the series must leave the identification numbers blank on their first payment vouchers.

Write "Series LLC # followed by the LLC number" in red ink on the top of all payment vouchers, tax returns, and correspondence.

We will assign an identification number to the rest of the LLCs in the series LLC. We will notify each series of its assigned number after we receive its initial payment voucher.
