EIN for a Delaware LLC: The Federal Number, the Delaware Steps (2026)

Is there a special EIN for a Delaware LLC?

No. An EIN for a Delaware LLC is the same 9-digit federal number the IRS issues in all 50 states. Delaware issues no EIN of its own, and no field on Form SS-4 asks for a Delaware version.

The EIN is federal by statute. Internal Revenue Code section 6109 gives the IRS the authority to assign identifying numbers, and one agency issues all of them. A Delaware LLC, a Wyoming LLC, and a Texas LLC each receive a 9-digit number in the same format, from the same office, on the same Form SS-4.

Nothing in the number encodes Delaware. The first 2 digits of an EIN are a prefix tied to the IRS campus that processed the application, not to the state of formation. Two Delaware LLCs formed on the same day receive different prefixes when different campuses handle them.

The practical result: an LLC that redomesticates out of Delaware keeps its EIN. The number attaches to the entity, not to the Division of Corporations file. What changes on a move is the state filing, the registered agent, and the franchise tax bill, and none of those touch the 9 digits.

When can a Delaware LLC apply for its EIN?

A Delaware LLC applies for its EIN after the Division of Corporations approves the Certificate of Formation. Line 1 of Form SS-4 carries the approved legal name, and a name the state has not yet approved fails the match.

Delaware creates the LLC at filing, not at application. Delaware Code Title 6, section 18-201 states the LLC comes into existence when the Certificate of Formation is filed with the Secretary of State, or at a later effective date named in the certificate. The EIN application follows that moment.

The Division of Corporations returns a stamped Certificate of Formation and a 7-digit file number. That stamped copy is the document to read line 1 from. Applying against a name from a reservation confirmation, a domain purchase, or a formation company's order screen is where the mismatches start.

Delaware holds a reserved name for 120 days. A reservation blocks other filers from taking the name. A reservation creates no LLC, holds no legal name, and supports no EIN application. Only the filed Certificate of Formation does.

The 2 filings run in a fixed order for every Delaware LLC: state first, IRS second. An owner who reverses them ends up with an EIN attached to a name Delaware never approved, and the correction runs through IRS correspondence rather than a form.

What does Form SS-4 take from the Delaware Certificate of Formation?

Form SS-4 takes the exact legal name onto line 1 and the formation date onto line 11. Line 8b records the member count, and line 8c records that the LLC was organized in the United States.

Delaware never appears as a state of formation on an LLC's Form SS-4. Line 9b asks for the state of incorporation only for corporations. An LLC checks line 8a, enters the number of members on 8b, answers 8c yes, and names the classification on 9a. That surprises owners who assume the form tracks their state.

Line 6 asks for the county and state where the principal business is located. For a Delaware LLC operated from Lisbon or Lagos, that field describes the operating location, not Dover. The IRS uses line 6 for administrative routing, and it carries no Delaware franchise-tax consequence.

Line 1 is the field that decides acceptance. Delaware Code Title 6, section 18-102 requires the name to contain "Limited Liability Company", "L.L.C.", or "LLC". The certificate shows exactly one of those 3 forms, with exact punctuation, and line 1 copies it character for character.

Line 11 takes the certificate's filing date, or the delayed effective date when the certificate names one. Delaware allows an effective date up to 180 days after filing, and an LLC that used one enters that later date on line 11 rather than the filing date.

Is the Delaware file number the same as an EIN?

No. The Delaware Division of Corporations issues a 7-digit file number at formation. The IRS issues a separate 9-digit EIN on Form SS-4. A US bank verifies the 9-digit EIN against the CP-575 letter.

The 2 numbers do different jobs. The 7-digit Delaware file number identifies the entity inside Delaware's own system, and it is the number the franchise-tax payment portal asks for each June. The 9-digit EIN identifies the entity to the IRS, to banks, to payment processors, and to every payer issuing a Form 1099.

A Delaware LLC receives the file number automatically and free with the Certificate of Formation. The EIN never arrives automatically. The IRS assigns it only when someone files Form SS-4, and the IRS fee for that filing is $0.

Owners who confuse the 2 numbers lose weeks at the bank. A bank opening a US business account asks for the CP-575 letter showing the 9-digit EIN and the LLC's legal name. A Delaware file number on a formation packet satisfies no part of that check.

The 2 numbers also come from different places on different timelines. Delaware issues the file number the moment the Division of Corporations stamps the Certificate of Formation. The IRS issues the EIN afterwards, on a separate application, and it never reads the Delaware file number to do it.

How does a Delaware LLC get an EIN without an SSN?

Enter "Foreign" on line 7b of Form SS-4 and fax the form to 855-641-6935 with a US-state address, or 855-215-1627 without one. The IRS answers a faxed SS-4 in 4 business days and charges $0.

Line 7b takes the word "Foreign" as a valid entry. The IRS built that instruction for responsible parties who hold no SSN and no ITIN. No passport upload, no notarised document, and no US visit enters the process at any stage.

The online assistant at irs.gov closes this route. That tool validates line 7b against an SSN or ITIN in real time and stops the session when neither exists. Fax, mail, and the international phone line at 267-941-1099 remain open, and all 3 issue the identical 9-digit number.

The fax route runs 4 business days when the SS-4 carries a return fax number. Mail runs 4 weeks. A Delaware LLC owned from abroad chooses between those 2 clocks, and the choice changes nothing about the number that arrives.

The responsible party on line 7a is a person, never an entity and never a registered agent. Delaware's Certificate of Formation lists no members, so the IRS learns the responsible party's identity from Form SS-4 alone. That is the only place the human behind a Delaware LLC is named in the process.

Does a Delaware LLC need a registered agent to get an EIN?

No. Form SS-4 asks for no registered agent on any of its 18 lines. Delaware Code Title 6, section 18-104 requires the registered agent for the LLC itself, and the Certificate of Formation names that agent.

Delaware requires a registered agent with a physical Delaware address for every LLC, for the life of the LLC. That requirement sits in state law and never touches the IRS. An LLC with a lapsed registered agent still holds its EIN, because the IRS runs no check against Delaware's register.

The 2 obligations fail in different directions. A Delaware LLC that loses its registered agent falls out of good standing with the Division of Corporations. A Delaware LLC with no EIN loses the bank account, the payment processor, and the ability to file Form 1065 or Form 5472. Neither problem fixes the other.

The EIN filing is priced on its own here, and it is priced first. A Delaware LLC that already exists needs the SS-4 and nothing else from us, so that single charge is the whole invoice and we say so before you reach the checkout. The classification advice on this page does not change based on what you buy.

Owners who have not filed with Delaware yet are in a different position, and pretending otherwise would be dishonest. Delaware demands a Certificate of Formation and a registered agent with a physical Delaware address before Form SS-4 can go anywhere. We offer formation with the first-year registered agent and an operating agreement as an optional +$197 add-on, with the Delaware filing fee passed through at cost and the registered agent renewing at $99/year, stated here and not buried. Delaware processing runs on Delaware's schedule, tracked separately from the EIN and never folded into the EIN's dates.

Does a Delaware LLC pay Delaware tax after it gets an EIN?

A Delaware LLC pays a flat $300 annual franchise tax, due June 1 every year under Delaware Code Title 6, section 18-1107. Delaware requires no LLC annual report. The EIN triggers no Delaware registration by itself.

The $300 is flat and unavoidable. Delaware charges the same $300 to an LLC with $0 of revenue and to an LLC with $10 million of revenue. Members, income, assets, and activity change nothing about the figure. Delaware corporations pay a different, scaled franchise tax; the LLC number is one flat charge.

A late payment costs $200 plus interest at 1.5% per month on the unpaid balance. Good standing lapses on the first missed June 1, not later, and a certificate of good standing is what a bank, an acquirer, or a payment processor asks for during review. Under Delaware Code Title 6, section 18-1108, the Certificate of Formation itself is cancelled after 3 consecutive years of nonpayment.

Delaware taxes no income of an LLC whose members are non-residents and which conducts no business inside Delaware. Delaware charges 0% state sales tax. An LLC that actually operates inside Delaware registers with the Division of Revenue for a business license and gross receipts tax, and that registration is where a Delaware state tax account number gets issued, separately from the EIN.

So a foreign-owned Delaware LLC selling to customers outside Delaware carries 2 recurring obligations, not 3: the $300 franchise tax to Delaware every June 1, and the federal filings the EIN attaches to. The EIN itself costs $0 in year 2 and every year after, because an EIN never renews and never expires.

How does the IRS classify a Delaware LLC?

By member count, not by state. One member produces a disregarded entity. Two or more members produce a partnership that files Form 1065 by March 15. Line 8b of Form SS-4 carries the count.

Delaware law and federal tax law describe the same company in 2 different vocabularies. Delaware Code Title 6, Chapter 18 governs the LLC as a legal entity, and it says nothing about federal classification. The IRS reads lines 8a, 8b, and 9a of Form SS-4 and assigns the default from the member count alone.

A single-member Delaware LLC with a US owner reports on Schedule C inside Form 1040. A 2-member Delaware LLC files Form 1065 and issues a Schedule K-1 to each member. The Delaware Certificate of Formation lists no members at all, so line 8b is the first document anywhere that records the count.

Elections override the default. Form 8832 moves the LLC to corporate treatment and Form 1120. Form 2553 moves it to S-corporation treatment and Form 1120-S, and Form 2553 is due within 2 months and 15 days of the start of the tax year the election covers. Neither election issues a new EIN.

A wrong entry on line 8b routes the LLC to the wrong annual return for the life of the company. That is the single field we check hardest, and correcting it after the CP-575 issues runs through IRS correspondence rather than an amended form.

What does a foreign owner of a Delaware LLC face?

A foreign-owned single-member Delaware LLC files Form 5472 with a pro-forma Form 1120 every year. A missed filing carries a $25,000 penalty under Internal Revenue Code section 6038A. The EIN is required before either form can be filed.

The Form 5472 obligation attaches to ownership, not to profit. A Delaware LLC with one foreign member and $0 of income still files, because the trigger is a reportable transaction with a related party, and a capital contribution from the owner counts as one. Formation-year filings catch owners who assumed a dormant company files nothing.

The $25,000 penalty applies per form, per year, and a second penalty accrues after the IRS issues a notice and 90 days pass without the filing. That figure sits above the entire lifetime cost of forming and maintaining most Delaware LLCs.

Two foreign members change the return. A 2-member Delaware LLC is a partnership, files Form 1065 by March 15, and carries withholding duties on effectively connected income instead of the Form 5472 obligation. Member count decides the whole compliance path, and member count lives on line 8b of Form SS-4.

None of these forms can be filed without the EIN. The 9-digit number is the identifier every one of them is filed under, which is why the EIN is step 2 of a Delaware LLC's life and not an afterthought.

Why do Delaware LLC EIN applications get rejected?

The name on Form SS-4 line 1 fails to match the Certificate of Formation. Delaware requires "Limited Liability Company", "L.L.C.", or "LLC" in the name, and the IRS compares the string exactly, punctuation included.

Four mismatches account for most rejections. A comma before LLC that the certificate omits. "L.L.C." typed where the certificate shows "LLC". An ampersand replacing the word "and". A trailing period the state never approved. Each of those is a different string to the IRS.

The IRS compares, it does not interpret. A human reading "Harbor Lane Ventures, LLC" and "Harbor Lane Ventures LLC" sees one company. The matching process sees 2 names, and the second one has no filing behind it.

The correction is slower than the application. A rejected SS-4 comes back by fax or mail, the owner re-files, and the 4-business-day fax clock restarts from zero. A single misplaced comma costs more days than the entire original filing took.

This is the check we run before anything is transmitted: your stamped Delaware Certificate of Formation against line 1, character by character, alongside the classification set on lines 8a, 8b, and 9a.

A rejection is not a denial, and nothing is lost except time. The IRS returns a reference code, the application is corrected, and it goes back in the queue. On the fax route that round trip adds 4 to 7 business days, which is the entire cost of getting line 1 or line 9a wrong the first time.

Which numbers does a Delaware LLC hold?

A Delaware LLC holds a 7-digit Delaware file number from formation and a 9-digit federal EIN from Form SS-4. A Delaware business license number is issued only to an LLC operating inside Delaware.

Source: IRS Form SS-4 instructions and the Delaware Division of Corporations, verified July 2026.

Only 1 of the 3 is federal, and only that 1 goes on a federal return. The Delaware file number identifies the LLC to the state that chartered it, and the business license number exists solely for an LLC trading inside Delaware. Neither is accepted anywhere the IRS asks for a taxpayer identification number.

Most Delaware LLCs hold 2 of the 3. A company formed in Delaware and operating elsewhere holds the file number and the EIN, and skips the business licence entirely. Holding all 3 is the exception rather than the norm, because Delaware is chosen far more often for its charter than for its market.

What does a Delaware LLC file each year?

A Delaware LLC pays $300 franchise tax by June 1 and files one federal return set by member count. A single foreign owner adds Form 5472 by April 15. Delaware requires no LLC annual report.

Source: Delaware Code Title 6, Chapter 18, the Delaware Division of Corporations, and IRS form instructions, verified July 2026. Deadlines shown for calendar-year filers.

Read the table as 2 stacks. Delaware asks for exactly one thing each year, on June 1, for $300. The IRS asks for a return whose identity depends entirely on the member count entered on line 8b of Form SS-4. An owner who gets line 8b right at the EIN stage never has to unwind a wrong return later, which is why llc ein application walks the form field by field, and form 5472 covers the $25,000 exposure in detail.

What does an EIN for a Delaware LLC cost?

The IRS charges $0 for an EIN, in Delaware and in every other state. Year 2 and beyond cost $0 on the federal side, because an EIN never renews. We file it for $97, faxed within 7 business days, or $127 filed within 24 hours with the IRS call included. Both deadlines are written.

Competitor prices verified July 2026. IRS routes cost $0 in every case; the EIN itself is never sold by the IRS. Business days = Monday to Friday excluding US federal holidays. Standard reaches the EIN in 16–19 business days total; Fast reaches it in 6 to 8 business days total. The Delaware $300 franchise tax is paid to Delaware and appears in no row above. Owners still forming can add Delaware formation with the first-year registered agent for +$197, plus the state fee at cost, with the agent renewing at $99/year; owners whose LLC already exists pay one row and nothing more.

What else do Delaware LLC owners ask about the EIN?

Owners ask about the filing deadline and the turnaround behind it, the $300 franchise tax due June 1, the $25,000 Form 5472 penalty, the 120-day name reservation, and whether an EIN expires. It never does.

What happens after Delaware stamps the Certificate of Formation?

Form SS-4 is filed against the stamped Certificate of Formation. Standard is $97, filed by fax within 7 business days, with the 9-digit EIN and the official IRS CP-575 letter in 16–19 business days total. Fast is $127, filed within 24 hours with the IRS call included, and 6 to 8 business days total.

We read your stamped Certificate of Formation against line 1 character by character, and set lines 8a, 8b, and 9a to your real structure. Filed by fax within 7 business days, or that fee is refunded. On Fast: filed and the IRS call made within 24 hours, guaranteed, or that fee is refunded. The EIN is priced on its own, so a Delaware LLC that already exists pays that one line and nothing more; if you have not filed with Delaware yet, formation with the first-year registered agent is an optional +$197 on Delaware’s own timeline, with the agent renewing at $99/year. If your Certificate of Formation is stamped and the bank is waiting, get an EIN for your LLC, filed right the first time.
