# Stripe Atlas vs Corpus

Stripe Atlas forms Delaware companies only: a C corporation or an LLC for $500, which its page says includes Delaware's filing fee, the IRS EIN filing and the first year of registered agent. The agent then renews at $100 a year. Corpus forms LLCs in all 50 states and DC, with one itemized total per state that includes year one of registered agent, then $99 a year with no automatic charge. Both can be driven by an AI agent; Atlas's agent tools prepare a draft that the founder pays for, signs and submits in the Stripe Dashboard.

## At a glance

| | Stripe Atlas | Corpus |
|---|---|---|
| Price | “$500, including Delaware filing fees and your first year of registered agent service” ([source](https://stripe.com/atlas)) | State fees + Corpus service fee, itemized per state before you pay |
| States and entities | Delaware only: “Delaware C corporations and LLCs, including C corporations formed as subsidiaries of an existing company” ([source](https://stripe.com/atlas)) | LLCs in all 50 states and DC; nonprofit corporations in most states |
| Registered agent | Year 1 included; “After the first year, registered agent service costs $100 per year” ([source](https://stripe.com/atlas)) | Year 1 included in the total; renews at $99/yr |
| Registered agent renewal | Renews automatically each year, per its docs; cancelling takes at least 30 days' notice, and prepaid fees are not refunded ([Atlas sign-up](https://docs.stripe.com/atlas/signup), [Atlas terms of service](https://stripe.com/legal/atlas)) | No automatic charge. Corpus reminds you before renewal and you choose whether to renew |
| EIN | IRS EIN filing is included in the $500 ([source](https://stripe.com/atlas)) | Optional add-on, priced separately, when available |
| Processing (Atlas's estimate) | “most companies are incorporated within one business day”; its docs say 1–2 business days ([Atlas](https://stripe.com/atlas), [Atlas sign-up](https://docs.stripe.com/atlas/signup)) | Filed after review; state times are on each state's page |
| Refunds | “We’ll refund your fee if we’re unable to support your business”; its terms say a declined applicant has “no recourse” ([Atlas sign-up](https://docs.stripe.com/atlas/signup), [Atlas terms of service](https://stripe.com/legal/atlas)) | Full refund before Corpus begins processing your filing |
| AI agents | An OAuth MCP tool and CLI prepare and validate a draft; the founder reviews, pays, signs and submits in the Dashboard ([Atlas with AI agents](https://docs.stripe.com/atlas/agents), [MCP](https://docs.stripe.com/mcp)) | Public MCP server, no account needed to start: an assistant collects your answers and hands you a prefilled link to review and pay |

## What Stripe Atlas charges

- “Atlas costs $500, including Delaware filing fees and your first year of registered agent service.” ([source](https://stripe.com/atlas))
- Stripe's pricing page calls it a “one-time setup fee (includes government fees and your first year of registered agent services)”. ([source](https://stripe.com/pricing))
- Also listed in the price: the IRS EIN filing, founder equity issuance and, for C corporations, “83(b) tax election filing”. ([source](https://stripe.com/atlas))
- “After the first year, registered agent service costs $100 per year.” ([source](https://stripe.com/atlas))
- Delaware's annual LLC tax is paid separately; Atlas's docs give it as “currently at a flat rate of 300 USD” and say it “isn’t prorated.” ([Atlas business taxes](https://docs.stripe.com/atlas/business-taxes), [Atlas company types](https://docs.stripe.com/atlas/company-types))

## What renews, and how to stop it

- “Atlas includes one year of registered agent services, which automatically renews each year.” ([source](https://docs.stripe.com/atlas/signup))
- The terms say the agent “may automatically renew, and you must pay any renewal fees for any renewal period.” ([source](https://stripe.com/legal/atlas))
- To cancel, the terms ask for “at least 30 days advance notice”; the agent stays appointed until you name a replacement. ([source](https://stripe.com/legal/atlas))
- “If you cancel the Registered Agent, you will not receive a refund for any prepaid fees.” ([source](https://stripe.com/legal/atlas))
- “We may revise the Fees at any time.” ([source](https://stripe.com/legal/atlas))

## First year in Delaware

- $500 covers Delaware's filing fee and year one of registered agent, and the IRS EIN filing is included too. ([source](https://stripe.com/atlas))
- Atlas's docs list Delaware's annual LLC tax at a flat $300, due June 1, on top of the $500. ([source](https://docs.stripe.com/atlas/business-taxes))
- Stripe Atlas: $500 for the first year, Delaware's filing fee included according to Stripe Atlas's own page.
- Corpus: $300 all-in, itemized: Delaware's state fees, the first year of registered agent and the Corpus service fee. (https://corpuslaw.us/form-an-llc/delaware)

Both totals are for forming a Delaware LLC. Atlas's $500 also includes an EIN filing, which the Corpus total does not. Delaware charges every LLC its annual tax whichever service forms it, and neither total includes that tax. Registered agent then renews at $100 a year at Atlas and $99 a year at Corpus.

## Registered agent, years 2 to 5

- Stripe Atlas: $400 at $100/yr (year 1 is included in the $500).
- Corpus: $396 at $99/yr (year 1 is included in the formation total).

## AI agents

Stripe Atlas:

- “Preparing or validating a draft through an agent or the CLI doesn’t submit it or form your company.” ([source](https://docs.stripe.com/atlas/agents))
- The atlas_company_formation MCP tool “lists, creates, retrieves, and advances draft applications”; the CLI has create_atlas_application and retrieve_atlas_formation. ([source](https://docs.stripe.com/atlas/agents))
- The Atlas agent docs say to connect to Stripe MCP and “authenticate with OAuth”. ([source](https://docs.stripe.com/atlas/agents))
- The founder then has to “Finish in the Stripe Dashboard to review documents, pay, sign, and submit your application.” ([source](https://docs.stripe.com/atlas/agents))
- “Another create request starts another application,” so a retried call opens a second draft. ([source](https://docs.stripe.com/atlas/agents))

Corpus:

- Public MCP server for LLCs in all 50 states and DC. Research and formation tools work with no account, key or OAuth.
- formation.checkout creates the order and a payment link (card through Stripe Checkout, or USDC on request, as of November 15, 2026) that the founder pays; nothing is filed until the founder confirms by email.
- Or the agent hands the founder a prefilled link to review, sign in and pay.
- A Corpus person reviews each filing before it goes to the state, unless the founder chooses to skip review on an expedited order.

## Where Stripe Atlas may suit you better

- You plan to raise venture capital. Stripe's docs say a Delaware C corporation is “Preferred by institutional investors who might be unable to invest in LLCs”, and Corpus forms LLCs and nonprofits, not C corporations. ([source](https://docs.stripe.com/atlas/company-types))
- You want founder equity, 83(b) filing and investor-ready documents in one package. Atlas lists founder equity issuance, “83(b) tax election filing” and documents “designed with Cooley”. ([source](https://stripe.com/atlas))
- You want the EIN inside the price. Atlas files it as part of the $500, and says “Founders from anywhere in the world can use Atlas”. ([source](https://stripe.com/atlas))
- You will run payments on Stripe anyway. Atlas lists “$2.5K in Stripe product credits” with the formation. ([source](https://stripe.com/atlas))

## How Corpus prices the same thing

State fees + Corpus service fee. Choose your state to see the current state fees and Corpus service fee before purchase. Registered-agent service for year 1 is included in your total. EIN filing is optional and priced separately, when available. Registered agent renews at a flat $99/yr after your included first year. We remind you before it's due; you're never charged automatically.
