Form a Series LLC, built to wall off risk.

A Series LLC gives you internal walls with one filing, one registered agent, and usually one annual report, which is far cheaper and simpler to run than a stack of separate LLCs. Separate LLCs, on the other hand, have decades of settled case law and are accepted everywhere, including by every bank and lender. The trade is cost and simplicity versus certainty. If you hold many assets in a series-friendly state and keep strict separation, the Series LLC wins on economics; if you need bulletproof, universally recognized isolation, separate LLCs are the conservative choice.

A growing but limited set, including Delaware, Texas, Illinois, Nevada, Tennessee, and about a dozen others, with the specifics differing on how series are created and reported. Many states still have no series statute at all. This is the single most important factor in your decision, because forming in a series state means little if your key protections aren't respected where you operate. We confirm your state offers the structure before filing and flag the mismatch if your operating state doesn't recognize it.

This is the honest weak point. If you form a Series LLC in Delaware but operate a series in a state that doesn't recognize series, it's unsettled whether that state's courts will honor the internal walls, and some may treat the whole thing as one LLC. The protection is strongest when you both form and operate in a series state. Where there's a mismatch, separate LLCs or a holding-company structure can be the safer route, and we'll tell you plainly which fits your footprint.

Yes, and this is where most of the protection is won or lost. If your series share a bank account or commingle funds, a court can disregard the internal walls and let a creditor of one series reach the assets of another. Each series should have its own account, its own books, and assets titled in its own name. Setting that up in the first weeks is what turns the legal structure into real-world protection.

Often, yes. The master gets an EIN, and any series that has its own employees, files its own tax return, or opens its own bank account will typically need its own EIN as well. Because banks usually require a separate EIN to open a separate account, and separate accounts are essential to the shield, many series end up with one. We obtain the master's EIN the same day and advise on which series need theirs based on how you'll bank and tax each one.

Federal tax treatment of series is still developing, and how each series is taxed can depend on its ownership and elections; some are treated as separate entities, some are reported together. It's an area where a Series LLC genuinely benefits from a CPA who has handled them, because the answer varies with your setup and state. We form the structure and keep your entity records clean; for the return itself, we'll point you to a professional, since we don't provide tax advice.

It's one of the most common reasons to form one. Investors put each property in its own series, so a claim tied to one building, an injury, a contractor dispute, a mortgage default, stays contained to that property's equity rather than threatening the whole portfolio. The cost savings over a separate LLC per property add up quickly. The keys are forming in a series state, keeping each property in its own series with its own account, and titling each deed to the correct series.

Yes, that's a core advantage. Once the master is formed, you can create additional series as your portfolio grows, usually by adding them in your operating agreement rather than making a whole new state filing, so each new property or venture gets its own shield without a new formation fee. Keep each new series properly documented, banked, and titled from the start. A compliance calendar helps you keep the whole structure organized as it expands.
