How to get an EIN for an LLC without paying a filing service
If your LLC is already formed with the state, you can usually get an EIN straight from the IRS for free in one session. The key thing people miss is the order: form the LLC first, then apply for the EIN. If you try to do it backwards, the IRS says your application may be delayed.
What an EIN actually does
An EIN is the federal tax ID for the business. Banks ask for it. Payroll providers ask for it. Vendors sometimes ask for it too. The IRS also says you generally need an EIN if you hire employees, operate a partnership or corporation, pay certain federal taxes, or change business structure or ownership.
For an LLC, the tax side can get confusing fast because the tax treatment depends on how many members the LLC has and whether it files an election. The IRS says a domestic LLC with two or more members is treated as a partnership by default for federal income tax purposes unless it elects corporate treatment. A single-member LLC is generally disregarded for income tax purposes unless it elects to be treated as a corporation, though the IRS still treats it as separate for some employment and excise tax purposes.
Do you need the EIN after forming the LLC?
Sometimes yes, sometimes not. A single-member LLC with no employees might not strictly need one for federal income tax purposes, but plenty of owners still get one because banks, payment processors, and state agencies often expect it. The IRS says you can still request an EIN for banking or state tax purposes even if you do not need one for federal tax purposes.
What you need before you start
| Item | Why it matters |
|---|---|
| Your LLC already formed with the state | The IRS says to register the legal entity with the state before applying for the EIN. |
| Responsible party SSN or ITIN | The online tool requires the responsible party's SSN or ITIN. |
| Correct legal name | The IRS says to enter the business name exactly as it appears on your registration or formation documents. |
| Fifteen quiet minutes | The IRS online session expires after 15 minutes of inactivity and cannot be saved for later. |
The fastest path: apply directly on the IRS site
The cleanest route is the IRS online application. The IRS says the tool is free, issues the EIN immediately if approved, and must be completed in one sitting. It is available during specific Eastern Time hours, not 24/7, and there is a daily limit of one EIN per responsible party per day.
That last rule catches people off guard. If you made a mistake earlier in the day, or opened an application for another entity, you may need to wait until the next day.
The IRS says: "If you are creating a corporation or LLC, form your entity through the secretary of state before you apply for an EIN. If you don't form your entity with the state first, your EIN application may be delayed."
Common mistakes that slow people down
- Applying before the LLC exists at the state level
- Typing the business name differently from the formation document
- Letting the session time out midway through
- Trying to get a second EIN for the same responsible party on the same day
- Paying a service for something the IRS offers free
When a filing service can still be useful
There is a difference between "you can do this yourself" and "nobody should ever pay for help." If you are already using a formation service to file the LLC, you may decide that having them bundle the EIN is worth it for convenience. That is a time trade. Just know the IRS itself does not charge for the EIN.
That is where a site like LLC Guidebook can be useful in practice: some readers want the free direct path, and some want a service that handles the paperwork stack together. The important part is understanding what is actually free and what is just bundled convenience.
Bottom line
If your LLC is already formed, getting an EIN is usually straightforward. Go to the IRS, use the online application during its posted hours, enter the LLC name exactly as it appears on the state filing, and finish the session in one go. That is the shortest route for most domestic LLC owners.
