Delaware LLC EIN Rejected: What to Do Next

Why does a Delaware LLC EIN application get rejected?

An EIN rejection feels alarming, but it is one of the most routine problems in forming a US company, and it rarely signals anything wrong with your Delaware LLC itself. The Employer Identification Number is issued by the IRS, not by Delaware, so a rejection is a federal-application problem layered on top of a company that already legally exists. In almost every case the cause is one specific, identifiable field or constraint — not a verdict on your business.

The single most common reason non-resident founders hit a wall is the IRS online EIN tool. That tool requires the responsible party to enter a US Social Security Number or ITIN. If you do not have one, the application cannot complete online at all — which many people read as a “rejection” when it is really the wrong channel. The correct route for a founder without an SSN is the paper Form SS-4, submitted by fax or mail, on which the SSN/ITIN line is simply left blank.

The other frequent triggers are an IRS reference number generated during the application (codes like 101, 102, 109, and 110, each meaning a different thing), a name or address that does not match your filed Certificate of Formation, the once-per-day EIN limit for a responsible party, or an SS-4 with missing or inconsistent entries. The good news is that each of these maps to a precise fix, which is what the rest of this guide walks through.

What do the IRS EIN reference numbers (101, 102, 109, 110) mean?

When the online application fails, the IRS often shows a reference number. Reading it correctly is the fastest way to know what to do next, because each code points at a specific cause rather than a vague “try again.”

• Reference 101 — name conflict. The IRS believes your LLC name matches an existing entity, or it cannot resolve the name against the responsible party. For a Delaware LLC, this usually clears by filing the paper SS-4 by fax so a human reviewer can see your exact Delaware-registered name. It does not mean your formation is invalid.
• Reference 102 — SSN/ITIN or name mismatch.The responsible party’s name and tax ID did not match IRS records. Re-check the spelling and the number, or apply on paper where no US ID is required.
• Reference 109, 110, 112, 113 — technical or system errors. These are usually temporary glitches on the IRS side. The fix is to wait and re-submit later, or switch to the fax route.
• Reference 114 — daily limit reached. The responsible party has already received an EIN that day. Wait until the next business day.

If you applied on paper rather than online, you will not see a numbered code — instead the IRS either returns the SS-4 or contacts you. In that situation, calling the IRS for businesses to ask the specific reason is the quickest way forward. Either way, the principle is the same: identify the exact cause before you re-apply, so you fix the right thing once instead of guessing.

Step-by-step: how do I recover from a rejected EIN?

The recovery is methodical, and rushing a second blind application is the mistake that turns a one-week delay into a one-month one. Work the steps in order.

• Step 1 — Get the exact reason. Read the reference number or online error, or call the IRS business line. Do not re-submit until you know which field or rule failed.
• Step 2 — Pull your Certificate of Formation.Open the document Delaware issued and note your LLC’s exact legal name, file number, registered agent, and address. Your SS-4 must match this precisely. See our Delaware LLC formation guide if you need to confirm what was filed.
• Step 3 — Correct the SS-4.Fix the field that caused the failure. If you are a non-resident, leave the responsible party’s SSN/ITIN line blank and write “Foreign,” confirm the entity type, and confirm the reason for applying.
• Step 4 — Choose the right channel. With an SSN or ITIN and the cause fixed, the online tool issues the EIN immediately. Without one, submit the corrected SS-4 by fax (fastest) or mail.
• Step 5 — Wait for the CP 575 letter. This is the official EIN confirmation. Keep it — banks and Stripe ask for it. Then move on to banking and payments.

The full federal-ID walkthrough, including how the SS-4 is completed for a foreign-owned LLC, is in our EIN for a Delaware LLC guide, and the end-to-end picture is on our how it works page.

How do I re-apply with Form SS-4 if I have no SSN?

This is the situation that affects most non-resident founders, so it is worth being explicit. You do not need an SSN, an ITIN, a visa, or a US address to obtain an EIN for a Delaware LLC. The online tool blocks you because it demands an SSN or ITIN for the responsible party — but the IRS issues EINs to foreign-owned Delaware LLCs every single day through the paper process. The path is straightforward once you stop fighting the online form.

On Form SS-4, you enter your name and your LLC’s exact name and address, name yourself (or another individual) as the responsible party, and leave the SSN/ITIN field blank, writing “Foreign” where the form asks for it. You then fax the completed SS-4 to the IRS fax number for international applicants. Fax submissions are typically processed in about 2 to 4 weeks; mail takes longer. There is no expedited IRS EIN service, so fax is the fastest realistic route for a founder without an SSN.

Which rejection cause applies to me, and what fixes it?

The fastest way to act is to match your symptom to its cause and its fix. The table below maps the common situations. Find your row, apply the fix, and re-submit once.

Whatever the cause, the prerequisites for a clean re-application are the same: a properly formed Delaware LLC with a registered agent in place (covered on our Delaware registered agent page), a correct legal name and address, and a single corrected SS-4 submitted through the right channel. Fix the one field that failed and resist the urge to fire off multiple applications, which can compound the problem.

Does a rejected EIN mean my Delaware LLC is invalid?

No, and this is the single most important reassurance in this guide. Your Delaware LLC comes into legal existence the moment the Certificate of Formation is accepted by the Delaware Division of Corporations — which happens in about 48 hours. The EIN is a separate, federal step that comes after formation. A rejected EIN application has no effect on your LLC’s legal status, its name, or its Delaware file number.

That distinction matters because some founders panic and consider re-forming the company. Do not. Re-forming would create a second, duplicate Delaware entity — and a second annual franchise tax obligation of a flat $300 per year. The correct move is always to keep the LLC you have and fix the federal application. Your existing company and the corrected EIN application belong together.

How does a rejected EIN affect banking and Stripe?

A US business bank account and a Stripe account both require a confirmed EIN, so a rejection does block those next steps until the EIN issues. That is the real-world cost of an EIN delay: banking and payments wait. It is also the reason fixing the rejection promptly matters more than it might first appear.

Once the EIN letter (CP 575) is in hand, you can apply to a US business account with Mercury, Relay, or Wise — fintech platforms that onboard non-residents online (each runs on FDIC-insured partner banks rather than being a chartered bank itself). The detail is on our Delaware LLC banking guide. You can then set up Stripe for your Delaware LLCto accept card payments. Approval at any bank or at Stripe is always the provider’s own decision — having a valid EIN is a prerequisite, not a guarantee. If a first application is declined, applying to a second provider is normal, because each reviews independently.

How can I avoid an EIN rejection the second time?

Almost every rejection cause is preventable on the re-application, and the habits that prevent it are simple. The point is to give the IRS one clean, internally consistent SS-4 that matches your Delaware paperwork.

• Match the Certificate of Formation exactly. The LLC name, spelling, and address on the SS-4 must be identical to the filed document.
• Use the right channel for your situation. No SSN or ITIN means paper SS-4 by fax — do not keep retrying the online tool.
• Respect the one-EIN-per-day limit. If you formed several companies, space the applications across business days.
• Fill every required field. A blank entity-type or reason-for-applying line is a common, avoidable rejection.
• Do not submit duplicates. Multiple simultaneous applications for the same LLC can create conflicts that slow everything down.

For non-resident founders, the broader path — formation, EIN, banking, Stripe, and ongoing federal filings — is laid out on our Delaware LLC for non-residents guide, which puts the EIN step in context with everything around it.

What federal filings follow once the EIN is finally issued?

Getting the EIN is the unlock, but it also starts the clock on a federal obligation that foreign-owned single-member LLC owners must not miss. If you are a non-US person owning a single-member Delaware LLC treated as a disregarded entity, the IRS requires Form 5472 each year, filed together with a pro-forma Form 1120. It reports reportable transactions between you and your LLC, such as capital you put in. The penalty for failing to file is $25,000 under IRC 6038A, so treat it as mandatory; the return is generally due April 15 (Form 7004 extends it). The detail is in our Form 5472 for Delaware LLCs guide.

Beyond that, your two standing obligations are Delaware’s flat $300 franchise tax, due June 1 each year from year two (a late payment adds a $200 penalty plus 1.5% interest per month), and your federal income tax position. A US non-resident is generally taxed only on income that is effectively connected to a US trade or business plus US-source FDAP income, and treaty relief applies only where a treaty is in force — so confirm your specific position with a CPA. The general picture is on our Delaware LLC taxes overview, and the full first-year cost is broken down on our Delaware LLC cost page.

A note on BOI / FinCEN beneficial ownership reporting

Beneficial ownership reporting under the Corporate Transparency Act changed significantly in 2025 and remains in flux. In March 2025, FinCEN issued an interim final rule that removed BOI reporting obligations for US-formed domestic reporting companies. Under that rule, only certain “foreign reporting companies” registered to do business in the US remain in scope, and US-formed entities are generally exempt from providing their information. A rejected EIN has no bearing on any of this.

Because this area is evolving and the rules may shift again, do not treat any summary as final. Before relying on your filing status, confirm the current FinCEN requirements at the source or with a professional. We monitor these changes and flag them, but the responsibility to file if required ultimately rests with the company owner.
