Use the IRS online EIN application if you only need an EIN and you feel comfortable entering basic business details yourself. It is free, direct, and the IRS says an EIN can be issued immediately after a completed online application [source: IRS]. Business formation services can still make sense, but mainly when you also need an LLC, corporation filing, registered agent service, compliance reminders, or help avoiding basic filing mistakes.
TLDR: For most small business owners, the IRS online EIN application is the fastest and cheapest route because it costs $0. For example, a single-member LLC owner with a Social Security number can often finish the application in one sitting and receive the EIN at the end. A formation service may charge anywhere from modest filing support fees to larger bundled packages, so it is better for people who want help with setup, not just the tax ID. If 100 new sole owners needed only an EIN, nearly all of them would save money by applying directly through the IRS.
What an EIN Is and Why You May Need One
An Employer Identification Number, or EIN, is a federal tax ID number issued by the IRS. Think of it as a Social Security number for a business, though the comparison is not perfect. Banks, tax agencies, payroll providers, vendors, and licensing offices may ask for it.
You may need an EIN if you:
- Hire employees.
- Form an LLC, corporation, or partnership.
- Open a business bank account.
- File certain federal business tax returns.
- Operate a trust, estate, nonprofit, or retirement plan.
- Want to keep your Social Security number off some business forms.
Some sole proprietors without employees can use a Social Security number instead. Still, many get an EIN for cleaner recordkeeping and banking. That is reasonable, as long as the application is done correctly.
Option 1: Applying Through the IRS Online
The IRS online EIN application is the direct route. You go to the IRS website, answer questions about the business, identify the responsible party, submit the form, and receive the EIN after approval. There is no government fee.
This is usually the right choice when your situation is simple. A single-member LLC, a partnership with clear ownership, or a corporation with standard records can often apply without outside help. The form asks for business name, mailing address, entity type, reason for applying, responsible party details, and expected employee information.
The biggest benefit is control. You enter the data yourself. You see the final answers. You receive the confirmation directly from the IRS. There is no middleman holding your confirmation letter or asking you to upgrade a package before you get basic records.
Honestly, it feels like some paid EIN pages are built to look more official than they are. That can be irritating. A rushed founder searching late at night may click an ad, pay a fee, and only later realize the IRS would have issued the number without charge.
Pros of the IRS Online Application
- No application fee: The IRS does not charge for an EIN.
- Fast result: Many approved applicants receive the number right away.
- Direct confirmation: You get the EIN confirmation from the source.
- Less data sharing: You do not give sensitive owner information to another company.
- Good for simple cases: Common small business structures fit the process well.
Cons of the IRS Online Application
- No hand holding: The IRS form does not give business planning advice.
- Session limits: If you pause too long, you may have to start again.
- Limited online availability: The tool may not be available around the clock.
- Easy to misclassify the entity: New owners sometimes confuse LLC tax status with legal structure.
- International applicants may need another method: Not every applicant fits the online process.
Expect to waste time on small details if your formation paperwork is not ready. A mismatch between your LLC name, state records, and your EIN application can create bank account delays later.
Option 2: Using a Business Formation Service
Business formation services are private companies that help create LLCs, corporations, nonprofits, and other entities. Many offer EIN assistance as an add-on or as part of a package. Some also provide operating agreement templates, registered agent service, annual report alerts, business license research, and tax election forms.
This option is not really about the EIN alone. It is about outsourcing the setup process. If you are forming an LLC for the first time and feel unsure about state filings, a paid service may reduce friction. The value depends on the accuracy of the service, the clarity of pricing, and whether you actually need the extras.
Pros of Business Formation Services
- Convenience: You can handle entity formation and EIN support in one place.
- Guided workflow: The forms may explain choices in plain language.
- Helpful add-ons: Registered agent service, operating agreements, and compliance reminders can help.
- Useful for busy owners: Some founders prefer paying to save administrative time.
- Better for bundled setup: If you need several filings, one provider can keep records together.
Cons of Business Formation Services
- Extra cost: You may pay for something the IRS provides free.
- Upsells: Packages can include services you do not need.
- Processing delay: Some providers apply after your state filing is complete, so you may wait.
- Data exposure: You share sensitive tax and owner details with a private company.
- Not a substitute for legal advice: Many services are document processors, not law firms.
IRS Online Application vs Formation Service: Which Is Better?
Choose the IRS online application if your business already exists, your details are clear, and you only need the EIN. This is the cleanest option for a sole proprietor, single-member LLC, standard partnership, or small corporation with simple ownership.
Choose a formation service if you are still creating the entity and want help with the full setup. This can be useful if you need state filing, an operating agreement, a registered agent, and compliance reminders. In that case, EIN help is just one part of the larger service.
Here is a practical comparison:
- Cost: IRS wins for EIN-only applications because it is free.
- Speed: IRS often wins if you have all details ready.
- Guidance: Formation services may win for first-time owners.
- Privacy: IRS wins because fewer parties see your data.
- Complex setup: Formation services may win when several filings are needed.
Information You Should Prepare Before Applying
Before applying, gather the following:
- Legal business name.
- Trade name, if any.
- State where the entity was formed.
- Business mailing and physical address.
- Entity type, such as LLC, corporation, partnership, or sole proprietorship.
- Name and taxpayer ID of the responsible party.
- Reason for applying.
- Expected number of employees in the next 12 months.
- Primary business activity.
The IRS generally limits EIN issuance to one per responsible party per day [source: IRS]. That rule matters if you manage several new entities. Do not rush through multiple applications and assume they will all be accepted the same day.
Common Mistakes to Avoid
- Using the wrong legal name: Match your state formation record exactly.
- Picking the wrong entity type: An LLC is a legal structure, but its tax treatment can vary.
- Applying too early: If your LLC is not formed yet, the name may not match state records.
- Losing the confirmation letter: Save the PDF immediately and back it up.
- Paying a private site by accident: Confirm you are on the official IRS website before entering data.
What to Do After You Receive the EIN
Once you have the EIN, save the confirmation notice. Banks often ask for it. You may also need it for payroll setup, sales tax registration, vendor forms, loan applications, and accounting software.
If you used a formation service, make sure you still receive the official IRS confirmation. Do not rely only on a dashboard entry or email summary. Keep your state filing confirmation, operating agreement, ownership records, and EIN notice in the same secure folder.
Final Recommendation
If all you need is an EIN, apply directly through the IRS. It is free, direct, and usually quick. Paying a third party just to request the number rarely makes sense.
If you also need to form an LLC or corporation, compare the full package price against the value of each service included. A serious provider can save time, but only if the services match your needs. Read the checkout page carefully, remove unwanted add-ons, and keep copies of every filing. The best choice is the one that gives you a correct EIN, clean records, and no surprise fees.
