Getting an EIN when the IRS online tool refuses you

A founder outside the United States forms a company, goes to the IRS website to get the tax number, works through the application, and hits an error. Usually reference number 101. Sometimes the session simply refuses to continue.

The immediate assumption is that something was entered wrongly. The second assumption, after a few attempts, is that this must require an expensive service. Neither is right.

What the IRS actually says

The IRS publishes the conditions for using its online application on the application page itself. You can use it if you are a domestic organisation formed in the United States, your principal place of business is in the United States or its territories, and you have the responsible party's Social Security number or individual taxpayer identification number.

It then says, in a line that is very easy to skim past, that you cannot use it if your principal place of business is outside the United States, and directs those applicants to apply by phone, fax or mail.

That is the whole explanation. The tool is not broken and you are not being rejected on the merits. You are outside the set of applicants it was built for.

What error 101 usually means

It is a general stop rather than a specific diagnosis, which is why it is so frustrating. In practice it tends to come from one of a few situations.

• A name conflict with an existing entity in the IRS system, sometimes in a different state.
• The responsible party has already been assigned the daily limit of EINs.
• The application involves a situation the tool does not handle, which includes many foreign ownership structures.
• Session data was lost to the fifteen minute timeout, which cannot be saved and resumed.

None of these are argued with. There is no appeal inside the tool. The resolution is to apply on paper.

The route that works

Form SS-4, prepared properly and submitted by fax or by mail. The IRS then issues the number and returns it to you.

Three parts of the form cause almost all the problems we see on applications people have attempted themselves.

The responsible party

This must be a natural person who controls the entity, not a company and not your agent. The IRS wants an individual with authority over the funds and assets. If you have no SSN or ITIN, you enter that you are a foreign person and provide the identifying details the form asks for. Naming the wrong person is awkward to correct later, because it requires a separate change of responsible party filing.

The entity classification

How you describe the entity determines how the IRS records it, and a mismatch between what the SS-4 says and what the state actually formed produces problems that surface much later, often when you try to make an election or file a return.

The reason for applying

There is a set of options and the right one depends on your situation. This is a small field that gets answered carelessly and occasionally causes a rejection.

How long it takes, honestly

Four to eight weeks is the realistic range for the paper route. Sometimes faster. Occasionally longer, particularly if the form comes back for correction, because a rejection restarts the clock.

You will see providers advertising much shorter times for applicants without an SSN. Treat those claims carefully. What we control, and what is worth paying for, is that the form is right the first time and that somebody follows it up rather than filing and forgetting.

What you cannot do while you wait

This is the part that catches people out on timing, so plan around it.

You cannot open a US business bank account without the EIN. In practice you cannot complete onboarding with most payment processors either. You cannot register for sales tax in most states. Which means that although the company legally exists within days of filing, the point at which it can actually receive money is governed entirely by the tax number.

For a founder abroad, that makes the realistic timeline from decision to first payment somewhere between six and ten weeks. Anyone quoting you days is either assuming you have an SSN or is not describing the process the IRS currently offers.
