What is the absolute cheapest way to give an AI agent an LLC?

DIY: file Articles of Organization yourself on a state portal (Wyoming charges $100) and rent a registered agent (~$29-49/yr). But you get zero agent governance — no operating agreement with delegation clauses, no proof of the agent's authority, no wallet binding — and you handle the EIN and compliance yourself. Cheap for a shell; incomplete for an operating agent.

Are $99 instant LLCs real companies?

They are series cells — legally recognized compartments inside a provider's master LLC. Real enough for many uses, but banks often refuse accounts for cells, the name reads as a subdivision of the provider, and your existence depends on their master. No state-standalone filing exists for your company.

Why does a standalone LLC cost at least a few hundred dollars?

Because the state itself charges a filing fee ($100 in Wyoming) and a registered agent must be maintained. Nobody can sell a real standalone LLC below state cost — offers that look cheaper are either series cells or exclude what an agent actually needs (EIN, agent, governance documents).

What does the $299 Agent Company add over DIY?

The EIN handled (including foreign owners), the registered agent for year one, and the Agent Charter: an operating agreement with agent-delegation clauses, the Agent Mandate with spending and risk limits, a Power of Attorney counterparties can rely on, wallet-to-entity binding, and a machine-readable mandate the agent enforces at runtime. That governance layer is the part no generic formation service ships.

The cheapest ways to form an LLC for an AI agent — honestly compared

From $100 DIY to $99 cells to $299 standalone to the offshore fortress: what each option really buys an autonomous agent, and where each one quietly falls short.

Pricing · Comparison · AI agents · 7 min read

The one-line answer: the floor for a real standalone LLC is the state itself (Wyoming: $100 + registered agent). $99 offers are series cells, not standalone companies. For an operating agent — one that signs, pays, holds wallets — the cheapest complete option is a standalone LLC with agent governance included: that's the $299 Agent Company.

Option 1 — DIY at state cost (~$130–150/yr)

File the Articles yourself on wyobiz.wyo.gov ($100), rent a registered agent (~$29–49/yr), request the EIN from the IRS (free, slow for non-US owners). Honest and real. What's missing is everything an agent specifically needs: an operating agreement that delegates authority to software with limits, proof of authority a counterparty will accept, wallet-to-entity binding, and someone tracking the annual report and the IRS Form 5472 trap for foreign owners ($25,000 penalty if missed). DIY is right for a shelf company; it's a lot of unpaid paralegal work for an operating agent.

Option 2 — the $99 series cell

Services like OtoCo spin up a cell of their master LLC in seconds for ~$99/yr. Genuinely clever, and the marginal economics are real (the master pays the state once). The tradeoffs bite agents though: banks routinely refuse accounts for cells; the legal name reads Provider LLC – YourAgent – Series 12; the cell's existence rides on the provider's master staying in good standing; and cross-state recognition of series shields is patchy. Fine for holding an NFT; shaky as the counterparty-facing identity of an agent doing business. (Florida just modernized series law — our day-one analysis covers when series structures do make sense: fleets.)

Option 3 — the $299 standalone Agent Company

A real, state-filed Wyoming LLC — own name, own EIN, bank-recognized — plus the Agent Charter: Operating Agreement with delegation clauses, Agent Mandate (powers, spending/risk caps, kill-switch), Authority Resolution & PoA, Wallet Authority Schedule, US tax memo, and the machine-readable mandate the agent enforces at runtime. Formed via MCP; payable by card or autonomously in USDC by the agent itself. What's included and why: the $299 breakdown.

Option 4 — the Nevis fortress (6,500 USDC)

When the agent custodies serious value, jurisdiction becomes the point: Nevis makes a creditor sue in Nevis, post a court-set bond, and prove fraud beyond reasonable doubt — with a 12-document Agent Charter and KYC handled. Not a first entity; the upgrade when the treasury justifies it. Details: Nevis LLC for AI agents.
