EIN for Stripe Atlas: Does Atlas Include One?
Stripe Atlas files an EIN application when it incorporates your US company. For non-US founders without an SSN, the IRS still processes that application by fax or mail, which can take weeks. Here is how the Stripe Atlas EIN works and how to control the timeline.

Short Answer
Stripe Atlas files an EIN application when it incorporates your US company, so you do not apply separately. But the EIN is only as fast as the IRS process behind it. Founders with a US SSN receive the EIN within days. Non-US founders without an SSN wait for the IRS to process Form SS-4 by fax or mail, which can take several weeks. You can file the SS-4 directly through ein.so for $49 to control the timeline.
Does Stripe Atlas Give You an EIN?
Yes. Stripe Atlas files an EIN application as part of its $500 incorporation service, so you do not submit a separate application. Atlas incorporates your Delaware C-Corp or LLC first, then requests the EIN from the IRS on your behalf.
The catch is timing. An EIN is only issued as fast as the IRS processes it, and the IRS treats non-residents differently from US founders.
| Founder type | EIN method | IRS timeline |
|---|---|---|
| US founder with SSN | Online or fax | Instant online; days by fax |
| Non-US founder, no SSN | Form SS-4 by fax | 4-7 business days |
| Non-US founder, mail filing | Form SS-4 by mail | 4-6 weeks |
Stripe Atlas handles the paperwork, but a non-US founder still waits on the IRS. The EIN does not arrive the moment your company is incorporated.
Why Do Stripe Atlas Founders Need an EIN Right Away?
A Stripe Atlas founder needs the EIN immediately because 4 critical steps depend on it. The company exists on paper after incorporation, but it cannot transact until the EIN arrives.
- Open the bank account. Stripe Atlas partners with Mercury, and Mercury requires the EIN to open your business checking account.
- Activate Stripe payments. Stripe needs the company EIN to enable live charges and payouts.
- File the 83(b) election. Founders electing 83(b) on their shares file within 30 days of share issuance, and the company needs its tax identity in place.
- File federal taxes. A Delaware C-Corp files Form 1120, and a foreign-owned LLC files Form 5472. Both require the EIN.
Until the EIN is assigned, the bank account, payment processing, and tax filings all stall. This is why the EIN timeline matters more than founders expect.

ein.so vs Stripe Atlas: How the EIN Application Compares
Both Stripe Atlas and ein.so file the same Form SS-4 with the same IRS. The difference is speed and scope. Stripe Atlas bundles the EIN into a full incorporation package; ein.so files the EIN on its own controlled timeline.
| Feature | Stripe Atlas | ein.so |
|---|---|---|
| Service | Incorporation + EIN + bank setup | EIN filing only |
| Price | $500 (incorporation bundle) | $49 Standard / $97 Express |
| EIN form filed | Form SS-4 | Form SS-4 |
| Non-resident SSN required | No | No |
| EIN timeline (non-resident) | Several weeks (batched) | 4-7 days Standard / 2-3 days Express |
| Best for | Founders who want full incorporation | Founders who already have a company or want the EIN faster |
Many founders incorporate with Stripe Atlas for the full startup stack and file the EIN through ein.so when they need it on a tighter schedule.
How Long Does the Stripe Atlas EIN Take?
The Stripe Atlas EIN takes several weeks for a non-US founder, because the IRS processes the underlying Form SS-4 by fax or mail. US founders with an SSN receive the EIN within days.
The IRS controls this timeline, not Stripe Atlas. A faxed SS-4 returns an EIN in 4-7 business days when the form is error-free. A mailed SS-4 takes 4-6 weeks. Errors on the form, such as the wrong entity type on Line 8a or a missing signature on Line 18, restart the clock. Filing the SS-4 directly by fax is the fastest non-resident path, which is why founders who need the EIN quickly file it separately.
