IRS EIN Error Code 105: Too Many Attempts

How people get here

Almost nobody hits a 105 on a first attempt. It is the end of a sequence. The application fails with a 109 or another technical error, the applicant resubmits, it fails again, they resubmit again, perhaps from a second browser or after tweaking an answer, and after enough of that the tool returns a 105 instead. The same thing happens to people who start the application several times because it timed out while they went to find a document.

The IRS built the limit to stop automated abuse of the EIN system. A real person retrying a broken form looks, to the counter, identical to a script.

What it means for your application

• No EIN was issued. If any of the earlier attempts had succeeded, you would have seen the number on screen. A 105 confirms none of them did.
• Your data is not the problem. A 105 says nothing about the business name, the responsible party, or the entity type. Do not change any of them to try to get past it.
• The lockout is per applicant, per period. In practice it clears after about a day. It does not carry over to fax or mail, which are processed by people, not by the website’s counter.

What to do

Option A: wait it out

Close every tab, stop for the day, and come back the next business day during the tool’s open hours. Start one fresh session with every answer ready. If it completes, you are done. If it fails again with a technical error, do not retry; go to option B.

Option B: fax the SS-4

This is the route that ignores the lockout entirely. Fill in Form SS-4, including a return fax number, and fax it. A person processes it and the number comes back by fax in roughly four business days. For most people who have already lost a day to a 105, that is faster than another round with the website, and it cannot produce another 105. How the fax route works.

What not to do

• Do not try again from a different browser, device or network. The limit is on the applicant, and the attempt still counts.
• Do not have a family member or colleague submit the same application under their own name as responsible party to get around it. The responsible party on an EIN is a legal statement about who controls the entity, not a login.
• Do not change the business name or entity type to see if a different version goes through. If it does, you now have an EIN issued to the wrong name or the wrong taxpayer.

105 and the one-per-day rule are different things

The IRS issues at most one EIN per responsible party per day, and a second application the same day returns reference number 114. That is a limit on successful applications. A 105 is a limit on attempts, successful or not. You can hit a 105 without ever having received an EIN, and most people who do have not.

Quick answers

How long does a 105 lockout last?

The IRS does not publish the window. In our experience it clears by the next business day if you stop trying. Continuing to try extends it.

Can I call the IRS to lift it?

The phone line cannot reset the online tool. For a domestic applicant, the agent will tell you to wait or to fax. International applicants can obtain the EIN on the phone line directly, lockout or not.

Did the IRS flag my business?

No. The counter is automatic and forgets you. There is no record of a 105 on the EIN that is eventually issued.
