Delaware . Series LLC available

Delaware Series LLC: one entity, many protected series.

Delaware statutorily authorizes the Series LLC . a master LLC that contains multiple internal series, each with its own assets, liabilities, members, and managers. Properly maintained, each series is liability-protected from the others. Common in real estate, fund management, and multi-brand operating businesses.

When a Delaware Series LLC makes sense

  • Real estate portfolios. Each property held in its own series. Liability on Property A does not reach Property B.
  • Fund management. Multiple investment vehicles under one umbrella.
  • Multi-brand businesses. Distinct brand lines isolated from each other.
  • Family wealth structures. Different beneficiaries assigned to different series.
  • Cost efficiency. One formation fee, one annual report (in most cases), many separated risk pools.

Frequently asked

Delaware Series LLC questions.

Does the Delaware Secretary of State allow series LLCs?

Only if Delaware's LLC act authorizes them, which not all states do. Where Delaware allows it, you file one certificate that lets the LLC create protected series inside it; where it does not, you form in a series-friendly state and register in Delaware as a foreign LLC. We confirm Delaware's exact status before you build on a series structure.

How do I file a series LLC with Delaware?

In a series state, you file a certificate of formation with the specific series language Delaware requires, then document each series internally under the master Operating Agreement rather than filing each with the SOS. We prepare the correct Delaware series certificate and the master agreement that makes the shield real.

How is a Delaware series LLC taxed?

Federal treatment is still developing; many owners file per series while others report under the parent, and Delaware may follow federal or apply its own rule. We flag the current Delaware and IRS treatment and obtain each series its EIN where its activity requires one.

Is a series LLC cheaper than multiple LLCs in Delaware?

Usually: you pay one Delaware formation fee for the parent rather than a fee per series, though some states add a per-series charge, and the bigger cost is disciplined record-keeping. Current Delaware figures and our service pricing are on the pricing page.

Can I convert my regular Delaware LLC to a series LLC?

Often yes where Delaware allows series, by amending the certificate and Operating Agreement to authorize series. It is not automatic; opening sub-accounts does not create a series. We handle the Delaware amendment and rebuild the agreement so the shield is actually in place.

Is a series LLC the same as a holding company?

No: a holding structure owns separate subsidiary LLCs each with its own filing, while a series LLC keeps them inside one entity as series. The holding route is more widely respected across states; the series LLC is cheaper. We help you weigh which fits Delaware and where you operate.

Can File.Business form a Delaware series LLC?

Yes. We confirm Delaware authorizes series, file the correct certificate with the required series language, build the master Operating Agreement, and set up EINs and records per series, so the structure is legally real rather than just sub-accounts under one name.
