A shell company is a legal entity that holds assets, a bank account, or a contract but conducts no operating business of its own, created to hold or move property under a name other than its true owner’s.
In plain terms
Strip away the word “shell” and it’s just a company with nothing inside it — no employees, no product, no office beyond a registered agent’s address. It can still own real things: a brokerage account, a yacht, a stake in another company. The entity is legal everywhere; what makes any particular shell company legitimate or not comes down entirely to whether its true owner is disclosed to the people the law requires it to be disclosed to.
How it works
Forming one is mechanically simple and inexpensive: a law firm or registered agent files articles of organization in a favorable jurisdiction, pays a modest fee, and the entity exists — often within a day. Delaware alone formed 334,461 new business entities in 2025, a more than 15% jump over 2024, and now has more than 2.28 million entities on file against a state population under a million; over two-thirds of the Fortune 500 are incorporated there, for the same reasons — predictable corporate law and a specialized Chancery Court, not secrecy alone.
Layering is where the structure gets opaque: a Delaware LLC owned by a Panama foundation, administered by a trustee in Switzerland, with no public document anywhere naming the actual human behind it. Each layer is a legal entity on its own; stacked together, they can take investigators years to trace, which is exactly what the Panama Papers and Pandora Papers leaks exposed at scale. For a foreign person who owns a US LLC and takes no US-source income through it, IRS Form 5472 is one of the few federal disclosure hooks left on the entity — it reports related-party transactions, and a late or missing filing carries a $25,000 penalty.
The numbers
- New Delaware entities formed in 2025: 334,461, up more than 15% from 2024.
- Total entities on file in Delaware: more than 2.28 million, as of 2025.
- Share of the Fortune 500 incorporated in Delaware: over two-thirds.
- Form 5472 penalty: $25,000 for a late or incomplete filing by a foreign-owned US disregarded entity, per occurrence.
- Typical setup cost: a basic shell company can be formed for a few thousand dollars, with annual maintenance in the hundreds to low thousands.
What people get wrong
That a shell company is inherently a criminal tool. Most aren’t. A Cayman fund vehicle pooling forty countries’ worth of investors, a single-purpose LLC holding one piece of real estate, a holding company sitting between a founder and an operating business — all shells, none hiding anything from anyone with a legal right to ask. The real line is disclosure: the same empty Delaware LLC that is routine estate planning when its owner is known to the IRS and any relevant court becomes a fraud or money-laundering vehicle the moment its owner is deliberately hidden from someone legally entitled to know. As of 2026, federal law no longer requires that disclosure for most domestic shells at all — see beneficial ownership — which means the burden of unmasking one has shifted back onto litigation, journalism, and the states that still ask.
