EIN Application: Free IRS Guide vs Paid Services

Get Your EIN for Free, or Know Exactly What You’re Paying For

Bottom line first: an Employer Identification Number (EIN) is a free nine-digit tax ID the IRS issues to identify your business, and “free” means free, no government fee to apply, receive, or use it, ever. Meanwhile, an entire industry of lookalike websites charges $50 to $300 for “EIN filing services” that submit the same free application you could finish before your coffee cools. This page is the cost-breakdown companion to our step-by-step EIN filing walkthrough.

That guide walks every screen of the application; this one shows the four free routes, prices the paid ones honestly, and names the few situations where paying actually buys something.

What an EIN Is, and Who Needs One

An EIN (also called a Federal Tax Identification Number) is a Social Security Number for your business: it goes on tax returns, bank paperwork, and every form where the IRS needs to know which business it is talking to. You must have one if you have employees, if the business is taxed as a partnership or corporation (which includes multi-member LLCs), if you file employment or excise returns, or if you run certain trusts, estates, or nonprofits, the full list lives on the IRS’s own EIN page. You should get one even when not required: a sole proprietor or single-member LLC can legally use an SSN, but an EIN keeps your SSN off every W-9, invoice, and vendor form you’ll ever send, and banks generally want an EIN to open the business account anyway. Privacy alone makes the free ten-minute application worth it.

The Four Free Ways to Get One (IRS Direct)

Online (the right answer for most): $0, about ten minutes, EIN issued on-screen the moment you finish. The tool currently runs seven days a week during extended hours (Eastern time), requires the responsible party to have an SSN or ITIN, must be completed in one sitting, and enforces the famous bottleneck: one EIN per responsible party per day. Print and save the confirmation letter before you close the tab. Fax (Form SS-4): $0, about four business days, the standard route when the online tool says no; the form and fax numbers live on the About Form SS-4 page. Mail (Form SS-4): $0 and four to six weeks, the patience option. Phone (international applicants): $0 via the IRS’s dedicated line for founders without an SSN or ITIN, with a completed SS-4 in hand when you call. Those last three routes are exactly where “no-SSN founder” services earn their keep, and where everyone else doesn’t need them.

Free IRS Application vs. Paid Services: The Real Numbers

The EIN is the free half of setup; the state half varies. Our verified table of LLC filing fees by state shows what each state actually charges to form and maintain an LLC.

Read the last row twice, because it is the entire consumer lesson: standalone EIN sites are charging a markup to type your answers into the free IRS tool, sometimes slower than doing it yourself. Some dress their pages to look official; the IRS’s actual application lives only on irs.gov, and the IRS never charges for an EIN.

When Paying Actually Makes Sense

Three honest cases. Bundled formation: if a service is already forming your LLC, letting it grab the EIN in the same flow costs little and saves a login; that is convenience pricing, not deception. No SSN or ITIN: international founders can’t use the online tool, and a service that manages the SS-4 fax-and-follow-up (doola built its business on exactly this) is buying real hassle-reduction, not a number. Genuine entity confusion: if you don’t yet know whether you’re forming an LLC, electing S-corp status, or who the “responsible party” should be, the fee is really buying the guidance, and you should compare it against our free formation cost calculator and S-corp vs. LLC calculator first. Outside those three cases, the math is unforgiving: paying $79 to skip a ten-minute form values your time at roughly $475 an hour, and if that’s real, you already have an assistant who can do this.

What You’ll Need Before You Apply

Ten minutes of prep prevents the classic reference-number errors. Have ready: the exact legal entity name as the state approved it (formation first, EIN second); any trade name/DBA; the responsible party, the human who controls the entity, with their SSN or ITIN (sole member for most single-member LLCs, a managing member or officer otherwise); the business address; state of formation; start date; closing month of the fiscal year (December for almost everyone); expected employee count for the next 12 months; and the reason for applying. Two rules bite the unprepared: the online session cannot be saved mid-way, and each responsible party gets one EIN per day, so batch founders (one person forming several LLCs) plan a calendar, not an afternoon. Name mismatches and same-day retries are also the root of most on-screen “reference number” rejections; when one appears, the fix is usually the SS-4 fax route, covered with the full error-code table in the step-by-step guide.

Common EIN Application Mistakes

Paying a lookalike site that implies the IRS charges a fee; it never does. Applying before the entity exists, then holding an EIN whose name matches nothing at the state. Typing the entity name loosely: the IRS wants it exactly as filed, punctuation included. Naming the wrong responsible party (it must be a controlling human, not another company, for most applicants). Losing the CP 575 confirmation letter, which banks ask for years later and the IRS does not reissue (it issues a substitute verification letter instead, after a phone call you won’t enjoy). Getting a second EIN for the same entity after a name change; names change fine, EINs follow the entity, and only real structure changes (sole proprietor to corporation, for instance) call for a new number. Skipping the state layer: the EIN is federal; sales tax and employer withholding accounts are separate state registrations.

After the Number Arrives

Save the confirmation letter as PDF and paper. Open the business bank account (bring the EIN letter and formation documents; the bank will also want the operating agreement more often than new owners expect). Start putting the EIN, never your SSN, on W-9s, invoices, and vendor forms. Register the state tax accounts that apply to you (sales tax, employer withholding). And file the number wherever your future self looks first, because “what’s our EIN?” is a question every business asks again at tax time, loan time, and payroll-setup time.

EIN, SSN, ITIN, and Timing

The three numbers, in one breath: SSN identifies a person; ITIN identifies a person who can’t get an SSN but has U.S. tax duties; EIN identifies an entity. Sole proprietors and single-member LLCs may run on an SSN but shouldn’t (privacy); partnerships, corporations, multi-member LLCs, and anyone with employees must have the EIN. (Which structure to form is its own decision; the SBA’s structure guide and our calculators cover that fork.) Timing follows one rule and a few triggers: entity formation first, then EIN, and get the number before the first bank visit, the first payroll run, the first credit application, or the closing when you buy an existing business. Total elapsed time when done in the right order: the state’s formation processing plus ten free minutes.

Frequently Asked Questions

Is an EIN really free?

Yes, completely: no fee to apply, receive, or use it, direct from the IRS. Any charge you see is a third party’s service fee for submitting the same free application on your behalf.

How long does it take to get an EIN?

Online: immediately on-screen when you finish. Fax: about four business days. Mail: four to six weeks. Phone (international applicants): during the call. The online tool runs seven days a week during extended Eastern hours and must be completed in one sitting.

Can I apply for an EIN before my LLC is formed?

Don’t. The IRS wants the entity’s exact legal name and formation details, so form the LLC or corporation with the state first, then apply. Sole proprietors, who have no state entity, can apply any time.

Do I need a new EIN if I change my business name?

Generally no; the EIN follows the entity through a name change (you notify the IRS of the new name). Changing the entity’s structure, like incorporating a sole proprietorship, is what typically requires a new number.

Why did the online tool reject me with a reference number?

The usual culprits: an entity-name conflict, a responsible party who already got an EIN that day, or details that need human review. The standard fix is filing Form SS-4 by fax; the common reference numbers and their meanings are broken down in our step-by-step EIN guide.

What if I’ve lost my EIN?

Check any filed tax return, your bank’s account-opening file, or the emailed/printed confirmation. Failing those, the IRS Business & Specialty Tax Line can verify it to an authorized person and mail a verification letter.

Ten Free Minutes, One Permanent Number

The EIN is the rare piece of business infrastructure with no catch: free, fast, permanent, and issued by the only party that can issue it. Form the entity, spend the ten minutes at irs.gov (or let your formation bundle handle it in-flow), save the letter, and put the $79 you didn’t spend toward something the government doesn’t give away.
