What the law requires.
7 rules, each in plain words.
Separate records for each series
The series liability shield depends on keeping separate records and on the operating agreement.
An operating agreement that provides for the series
It must set out the series, the separate records and the separate assets.
Delaware registered series: a certificate for each series
The certificate of registered series costs $110.
Delaware: an annual LLC tax of $400, due June 1
Each registered series adds $100 to the tax.
Delaware: a $50 penalty per registered series if the tax is late
Wyoming: $10 for each series designated or established
A registered agent
The registered agent keeps an in-state registered office for the LLC.
How Entiva forms it.

- 6Open the records for each series
Entiva keeps a separate record for each series. It is never filed with a state.
- 7Obtain the parent LLC's EIN (US tax number)
Whether a series needs its own EIN depends on how it is taxed.
- 8Elect a tax classification (optional)
Form 8832 lets the LLC choose how it is taxed.
- 9Register for state and local taxes
