It’s your business’s ID badge in the eyes of banks, payroll providers, and government agencies.

Everyday examples of understanding the importance of an Employer Identification Number (EIN)

The fastest way to understand why an EIN matters is to see it in action. Here are everyday, real‑world situations where business owners suddenly realize, “Oh… I really do need an EIN.” These are the best examples of how that nine‑digit number quietly runs the show behind the scenes.

Picture a few different people:

  • A freelance graphic designer going from side hustle to real business.
  • A couple opening a small coffee shop.
  • A tech founder launching an app with a business partner.
  • A landlord moving from one rental to a small portfolio.

All of them hit the same wall at some point: “We can’t move forward until we have an EIN.” These examples of understanding the importance of an Employer Identification Number (EIN) show you exactly when and why that happens.


Example of an EIN in action: Opening a business bank account

One of the clearest examples of understanding the importance of an Employer Identification Number (EIN) happens at the bank counter.

You walk in ready to open a business checking account. The banker smiles, pulls out the forms, and then asks:

“What’s your business’s EIN?”

If you’re operating as an LLC, partnership, corporation, or you plan to hire employees, most banks will not open a proper business account without an EIN. They don’t want your personal Social Security Number (SSN) tied to every transaction.

Why banks care:

  • They must comply with IRS reporting rules.
  • They use your EIN to report interest and certain payments.
  • It helps separate your personal identity from your business identity.

For a single‑member LLC, this is often the first wake‑up call. Technically, the IRS allows some single‑member LLCs to use the owner’s SSN, but many banks have their own policies and require an EIN anyway.

Key takeaway: If you want a real business bank account that looks and acts like a business, not a personal slush fund, an EIN is your ticket.

Hiring workers: one of the best examples of EIN importance

Another powerful example of understanding the importance of an Employer Identification Number (EIN) shows up the moment you decide to hire help.

Let’s say your online store is booming and you’re ready to bring on your first employee. As soon as you run payroll, you’re responsible for:

  • Withholding federal income tax
  • Withholding and paying Social Security and Medicare (FICA)
  • Filing employment tax returns

To do any of that correctly, you need an EIN. Payroll providers, HR platforms, and the IRS all expect it.

Real example:

A bakery owner starts by paying a friend “under the table” in cash. Then she wants to:

  • Put the friend officially on payroll
  • Offer direct deposit
  • File proper W‑2 forms at year‑end

The payroll company immediately asks for the bakery’s EIN. Without it, they can’t set up the account. This is one of the best examples of how an EIN is not just a tax number; it’s a prerequisite for doing things the right way.

Partnership and LLC examples of understanding the importance of an EIN

If you’re in business with someone else, the need for an EIN becomes even clearer.

Example of a partnership:

Two friends start a landscaping business. They split profits 50/50. The IRS treats them as a partnership. Partnerships must:

  • File an annual partnership return (Form 1065)
  • Issue Schedule K‑1s to partners

All of this requires an EIN. The partnership can’t file under one partner’s SSN, because the business is a separate tax entity.

Example of a multi‑member LLC:

A tech startup forms a multi‑member LLC. Even if it doesn’t have employees yet, the IRS treats it similarly to a partnership for federal tax purposes (unless it elects corporate taxation). To file its return, open bank accounts, and sign up for certain platforms, it needs an EIN.

These partnership and LLC scenarios are classic examples of understanding the importance of an Employer Identification Number (EIN) beyond just “big corporations.” If you’re not a solo act, an EIN is usually part of the basic setup.


Licensing, permits, and vendor accounts: quiet but powerful examples

Many business owners don’t expect this one: government agencies and large vendors often ask for your EIN on their forms.

Examples include:

  • Applying for a state sales tax permit
  • Getting a city business license
  • Registering as a vendor with a large company or government agency

A restaurant, for instance, may need:

  • A state sales tax ID
  • A health department permit
  • A liquor license

On those applications, the form often asks for an EIN. The license office wants a consistent way to identify your business for tax and compliance purposes.

Similarly, if you want to sell to larger companies or bid on government contracts, their vendor registration portals typically require an EIN. It signals that you’re a real business, not just an individual sending random invoices.

For U.S. federal contracting, you’ll see EIN‑related requirements in systems like SAM.gov (run by the General Services Administration): https://sam.gov

These are subtle but very real examples of understanding the importance of an Employer Identification Number (EIN) in day‑to‑day operations.


Online platforms and fintech: modern 2024–2025 examples

In 2024–2025, more business runs through online platforms and fintech tools than ever. That shift has created new examples of understanding the importance of an Employer Identification Number (EIN).

Consider:

  • Payment processors and merchant accounts (Stripe, PayPal, Square‑type services)
  • Online payroll and HR platforms
  • E‑commerce marketplaces

Many of these services:

  • Require an EIN if you’re registering as a business entity
  • Use your EIN for tax reporting on Forms 1099‑K and similar documents

If you try to scale from “just me with a PayPal account” to “registered business with staff and multiple revenue streams,” you’ll hit EIN requirements quickly.

Real example:

A creator sells digital products under her personal name. She later forms an LLC for liability protection and branding. When she updates her accounts with the LLC name, the platforms ask for an EIN to match the business profile, not her SSN.

This is a modern example of how an EIN supports:

  • Brand separation
  • Tax reporting accuracy
  • Cleaner accounting

Protecting your privacy: an underrated example of EIN importance

Another subtle but powerful example of understanding the importance of an Employer Identification Number (EIN) is simple: protecting your personal information.

If you invoice clients, sign contracts, or fill out W‑9 forms as a business, you’ll be asked for a taxpayer identification number. Without an EIN, that usually means handing out your SSN to:

  • Clients
  • Vendors
  • Platforms
  • Sometimes even independent contractors you work with

Using an EIN instead of your SSN:

  • Reduces how often you share your personal number
  • Lowers your exposure to identity theft
  • Looks more professional on invoices and contracts

This privacy angle is one of the best examples of why even solo entrepreneurs often get an EIN, even when the IRS technically allows them to use an SSN.

You can see how the IRS treats SSNs and EINs as taxpayer IDs on forms like the W‑9 here: https://www.irs.gov/forms-pubs/about-form-w-9


Planning for growth, investors, or selling your business

Think a few years ahead. If you want to:

  • Bring in investors
  • Add new partners or members
  • Convert to a corporation
  • Eventually sell your business

You will need clean, separate business records. An EIN is a building block for that.

Real example:

A small marketing agency starts as a single‑member LLC using the owner’s SSN. After a couple of years, she brings on a partner and wants to show:

  • Clear business tax returns
  • Separate business banking history
  • Stable records for potential investors

At that point, she applies for an EIN, but it would have been smoother to start with one from day one. This is a longer‑term example of understanding the importance of an Employer Identification Number (EIN): it’s not just about this year’s taxes, but about making your business easier to grow, value, and eventually transfer.


Nonprofits and EINs: another real‑world example

If you’re forming a nonprofit organization, an EIN is not optional.

To:

  • Apply for federal tax‑exempt status (like 501(c)(3))
  • Open a bank account for the nonprofit
  • Receive grants or donations through many platforms

…you’ll need an EIN. Donors, grantmakers, and government agencies all use it to identify your organization.

The IRS explains EINs for nonprofits and tax‑exempt status here: https://www.irs.gov/charities-non-profits/applying-for-tax-exempt-status

This is a clear example of understanding the importance of an Employer Identification Number (EIN) outside the classic “for‑profit business” world.


How to get an EIN in 2024–2025 (and common mistakes)

Once you see all these examples, the next question is obvious: how do you actually get an EIN?

In most cases, you can apply online through the IRS if your business is in the United States or U.S. Territories. The IRS online EIN assistant is typically available Monday–Friday and issues the number immediately after you complete the application.

Key points:

  • There is no IRS fee to apply for an EIN.
  • Be wary of third‑party sites that charge for what you can do directly with the IRS.
  • You need to know your business structure (sole proprietorship, LLC, partnership, corporation, nonprofit, etc.) before you apply.

Common mistakes include:

  • Applying under the wrong entity type, then having to fix it later.
  • Forgetting to update the EIN information when ownership or structure changes.
  • Getting multiple EINs for the same business without a valid reason, which can complicate tax records.

Understanding this process ties directly back to all the earlier examples of understanding the importance of an Employer Identification Number (EIN): once you know where you’ll need it, the application questions make a lot more sense.


Quick recap: when these examples mean you probably need an EIN

If you recognize yourself in any of these situations, it’s time to get or confirm your EIN:

  • You want a separate business bank account for your LLC, partnership, corporation, or nonprofit.
  • You plan to hire employees or already pay anyone as an employee.
  • You’re forming a partnership or multi‑member LLC.
  • You’re applying for licenses, permits, or vendor status with larger organizations.
  • You use online platforms and want them to treat you as a business, not just an individual.
  • You’re tired of putting your SSN on every W‑9 and invoice.
  • You’re planning for investors, growth, or sale of the business.

These are not abstract scenarios. They’re real, concrete examples of understanding the importance of an Employer Identification Number (EIN) that play out every day for small and growing businesses.


FAQ: examples of EIN use and common questions

Q1. Can you give a simple example of when I absolutely need an EIN?
If you hire your first employee, you absolutely need an EIN. You can’t correctly withhold and report payroll taxes without it, and payroll providers will insist on having your EIN before they run payroll.

Q2. Are there examples of freelancers who should still get an EIN, even if it’s not required?
Yes. A solo freelancer who invoices multiple corporate clients often chooses to get an EIN so they can put that number on W‑9 forms instead of their SSN. It’s a privacy and professionalism move, even when the IRS would allow them to use their SSN.

Q3. What’s an example of a business that does not need an EIN right away?
A solo consultant with no employees, operating as a sole proprietorship, filing under their own SSN, and not needing a separate business bank account might operate without an EIN at first. But as soon as they hire help, form an LLC, or start working with larger vendors, an EIN usually becomes necessary.

Q4. Are there examples of using one EIN for multiple businesses?
Generally, each separate legal entity needs its own EIN. For instance, if you own two LLCs, each LLC typically gets its own EIN. There are limited exceptions (like certain divisions within one corporation), but most small business owners should assume one entity, one EIN.

Q5. What’s an example of a mistake people make with EINs?
A common mistake is applying for multiple EINs for the same business because the owner forgot they already had one, or changed the business name and thought they needed a new number. That can confuse tax records and create extra work with the IRS.


When you look at all these real‑world cases side by side, the pattern is pretty clear: the more serious and structured your business becomes, the more situations you’ll encounter where an EIN isn’t just helpful—it’s expected. Keeping these examples of understanding the importance of an Employer Identification Number (EIN) in mind will help you set up your business in a way that’s cleaner, safer, and ready to grow.
