How long does an EIN take when the online tool is closed to you

I spent last year telling people to get an ITIN before applying for their EIN. That advice adds seven weeks to a chain that never required them, and I gave it in writing more than once. Do not put an ITIN in front of an EIN.

That pair of rules is the whole article. Never apply for an ITIN before the EIN unless your own tax position needs one, and always copy the entity name off the stamped certificate. The correction took me ten seconds to check. I never checked it, and I still find that embarrassing.

My mistake sat in one specific place, on line 7b of Form SS-4, which asks for the responsible party's own taxpayer number. I read that box as a requirement to supply a 9 digit number. It is not one, and the instructions say so in a single sentence I had never read to the end: “Enter 'foreign' or N/A on line 7b if the responsible party doesn't have and is ineligible to obtain an SSN or ITIN. An entry is required.”

An entry is required. A taxpayer number is not. Those are different sentences and I collapsed them into one.

Seven weeks, and where they go

Seven weeks is the unit I now use here, and it comes from the agency rather than from anybody's anecdote. The IRS says to “allow 7 weeks for us to notify you about your ITIN application status”, and adds that “it can take 9-11 weeks if it's tax season (January 15 to April 30) or if you applied from overseas”. Both conditions describe most foreign owners.

Seven weeks bothers me more than is reasonable. It is the gap between doing this properly and doing what everybody tells you, and the gap buys nothing at all.

Put the two sequences beside each other and the cost of my old advice becomes arithmetic rather than opinion. On my advice you form the entity, which runs one to ten days depending on the state, then you file the W-7 and wait somewhere between 49 and 77 days by the published allowance, and only then do you send the SS-4. Ignore me, and you send the same SS-4 in the same week with the word foreign written into box 7b.

The difference is the entire ITIN wait. Between 49 and 77 days, bought with nothing, and 77 is the figure that applies to most people reading this, because applying from overseas is one of the two conditions that widens the window. The ITIN can be applied for afterwards, in parallel, while the company is already open and trading.

The second thing I had wrong

While I was checking the first error I found a second one in my own text. I had been telling people that the fax route runs about four weeks.

It does not. The instructions say “Under the Fax-TIN program, you can receive your EIN by fax generally within 4 business days.” Four business days. The four week figure belongs to the postal route, where the wording is “You will receive your EIN in the mail in approximately 4 weeks”, and I had merged the fast and the slow paper options in my head into a single slow one.

So the paper route is not one thing. It is a fast one and a slow one, and a fax number is the whole difference. I was the reason a number of people believed otherwise.

The line that is open 17 hours a day

The route almost nobody uses is the telephone, and the hours are why I would try it first. The instructions open it to anybody with “NO legal residence, principal place of business, or principal office or agency in the United States or U.S. territories”, who “may call 267-941-1099 (not a toll-free number)” on weekdays to obtain an EIN, and the published window runs from 6 in the morning until 11 at night, Eastern time.

That is 17 hours a day. The domestic line offers 12. It is the opposite of what everybody assumes about applying from outside the country, and the assumption is doing real damage, because the people who most need the telephone route are exactly the people who have decided in advance that it was not built for them.

Do the time zone arithmetic before you dismiss it. Eleven at night Eastern is 4 in the morning in Lisbon. Six in the morning Eastern is 11 in the morning there, which is an ordinary working hour. My instinct is that people skip the telephone because of the language rather than the hours, and that is a different objection deserving a different answer.

One thing I had wrong here too, and it matters if you plan around it. The call is not the end of the process. The instructions require that you “mail or fax the signed Form SS-4 (including any third-party designee authorization) within 24 hours to the IRS address provided by the IRS representative”. You get the number on the call and the paperwork still has to follow within a day.

Written applications go on Form SS-4 to Internal Revenue Service, Attn: EIN International Operation, Cincinnati, OH 45999. There is one address and one form. No online equivalent exists for this population, which is the whole reason the paper route survives in 2026.

I went looking for a published service standard behind those 4 business days. Nine agency pages and two afternoons, and I have not found one anywhere. Every third party figure I read cited no source at all, and none pointed at the Form SS-4 instructions, where both published numbers actually live, free, and first in the results for the form number.

The fork on line 7b

How long does an EIN take depends entirely on one box, and the gap between the answers is enormous.

Write an SSN or an ITIN into 7b and the online application hands your number back inside the same session, usually in about four minutes, with a notice you can save before you close the tab. Four minutes against 4 business days by fax is the whole of the difference that one box makes. That route costs nothing at all. Any service charging for it is charging you to type. The going rate for that typing sits near 250 dollars in the packages I have looked at.

If you cannot, that door shuts and you are on paper. Fax is generally four business days, post is approximately four weeks, and the telephone is the same afternoon with a form to follow. Nothing about holding an ITIN unlocks the fast route later. It never did and it was never meant to, and the reason the belief is so durable is that both numbers are nine digits, both are issued by the same agency, both appear on the same form within a few lines of each other, and nothing on that form or in its instructions ever says out loud that one has nothing to do with the other. That belief has cost people more time than any other misunderstanding here, and I helped spread it.

A short digression about the word disregarded, because it frightens people who meet it on line 9a. It is a tax classification and not a judgement about the company. A disregarded entity is one the IRS looks through to its owner for income tax, and it has no bearing on liability, on the bank account, or on whether anybody treats the company as real. None of which makes the word less alarming in a box you are about to tick. Anyway, back to the form.

What the online tool will refuse

The tool refuses people for reasons it explains badly, and the explanation it does give points at the wrong thing often enough that a rejection tells you very little. I have watched all four of these happen.

Never leave the online application half finished, because it will not wait for you. It runs weekday hours in Eastern time rather than around the clock. It has no save and resume. A timeout costs you the session and everything typed into it, and I have seen that happen to people who were being careful rather than to people who were not.

Then there is the responsible party rule, which the instructions state as a flat prohibition: “Unless the applicant is a government entity, the responsible party must be an individual (that is, a natural person), not an entity.” A holding company cannot name itself for its subsidiary. A human being has to sign up for it.

One more that only bites people forming several entities at once. The published limit is that “EIN issuances are limited to one per responsible party, per day”, and the instructions add that “for trusts, the limitation is applied to the grantor, owner, or trustor”. Four companies means four days, or four different responsible parties. I watched somebody discover that at five on a Friday afternoon, with a closing booked for the Monday.

Where the weeks actually go

I costed the whole chain for a foreign owned single member LLC, taking the middle of every published range rather than the good end. State filing runs five to fifteen business days, a spread of two weeks on the first step alone. The EIN by fax is generally four business days, and I allow a week for it with delivery in both directions. Bank onboarding takes another one to three weeks once the letter is in your hands.

That lands near five weeks from decision to a funded account, if you run the whole thing as a queue. Five weeks, for 4 business days of actual government work.

Now start cutting that number down. The order matters more than the effort. Expedited state filing takes a week or two off the front, and in most states it costs less than the fortnight it saves. The telephone route removes the fax wait from the middle, at the price of a signed form within 24 hours. Best realistic case lands near three weeks, and I would not promise anybody fewer.

Run the independent steps in parallel, which almost nobody does. Choosing the bank, reading its published document list, getting identity documents certified, appointing a registered agent: none of those need an EIN and all of them get left until after it. My suspicion is that most of a long timeline is nobody doing anything, rather than any queue being slow, and I would bet on that without being able to prove it.

The lines that bounce applications

Always copy the legal name off the stamped certificate rather than typing it from memory. It is the cheapest fix in this article. It is also the one that fails most often.

Line 1 wants that name character for character as the state holds it. Suffixes are where it goes wrong, with the bare LLC set against the dotted version and against the words Limited Liability Company written out in full, and a mismatch either bounces the form or, worse, succeeds, at which point you own two federal records that disagree with each other, one at the IRS and one at the state, both of them correct as far as their own clerk is concerned, and no process anywhere designed to reconcile them without you paying somebody to write letters.

Line 9a wants the entity type. A single member LLC owned by one foreign individual is disregarded by default. Tick the corporation box because it sounds more serious and you have committed to a filing regime you did not intend, and undoing it means Form 8832 and another wait.

The box almost nobody uses

Near the bottom of the SS-4 sits a third party designee section, and it solves the problem most foreign applicants describe as unsolvable. The instructions point at line 18 for it. If you have no United States fax and no appetite for the international line from eight time zones away, you can name an accountant or agent in the States to receive the number for you. Their authority ends the moment the EIN issues, so this is far narrower than a power of attorney.

The instructions are specific: “EINs are released to authorized third-party designees by the method they used to obtain the EIN (online, telephone, or fax); however, the EIN notice will be mailed to the taxpayer.” The designee gets the digits and you still get the letter.

There is one trap printed right next to it, and I would have walked into it. “If the third-party designee's address or telephone number matches the address or telephone number of the taxpayer, the application must be mailed or faxed.” Name your own registered agent, whose address is also yours on paper, and you have quietly closed the fast route you were trying to open.

Why the published figure is a range and not a number

The agency publishes four business days for fax and approximately four weeks for post. It does not publish a distribution, a median, or anything that would tell me whether those are middles or optimistic ends, and that omission is why every guide on this subject quotes a different figure with nothing underneath it.

My guess, and I want it read as a guess, is that the paper route is not one queue but at least two. A form where every box matches the state record character for character is a different job from one that needs a person to resolve a discrepancy, and nothing in the published guidance separates the two cases even though they are obviously not the same work. That is a guess with no evidence behind it.

What follows from it, if I am right, is that the part of the timeline you control is not the queue. It is whether your form goes into the easy pile, and that is decided entirely by whether you copied the entity name off the stamped certificate or typed it from memory.

Keep the letter, not the number

The IRS issues the CP 575 confirmation once and will not reprint it. Save it twice, in two places, on the day it arrives.

The replacement is Letter 147C, and it comes by telephone. That means a call to the Business and Specialty Tax Line, an authorised person on the account, and the address exactly as the IRS holds it rather than as you use it now. Banks want the document rather than the digits, so the thing you are waiting on is paper. A CP 575 that took 4 business days to earn can cost you several weeks to replace, which is the whole argument for saving it on the day it arrives, in two places, and not both of those places on the machine you are reading this on.

What this article cannot tell you

I would like to tell you the rejection rate on first attempts and I cannot. I have tried twice, across the same 9 agency pages, and the IRS publishes nothing resembling it. Nobody else does either, and I do not know whether it differs between the 4 business day fax route and the telephone one. I am not going to estimate it from the handful of cases that reach a website, because that is the most biased sample in existence.

Everything else here is checkable against the form and its instructions, both free on the IRS site, and I would rather you checked than took my word for it. That is not modesty on my part. I have been wrong twice in public about this one form, and both times the wording was sitting in the instructions.

None of this is advice on your filing position. A treaty, a classification election, or an information return obligation you have not met changes what you should be doing entirely, and a single member LLC owned by a non resident carries one of those that surprises somebody every spring.

The part that still bothers me is that the wait was free to avoid. Not cheap to avoid, not quick. Free. A single word in a single box on a form that was already being filled in. I have not worked out how to say that in one sentence without it sounding like an accusation, and the somebody in this case was me.
