How to Get Your EIN for Your Nail Salon — And Why You Need One

SimpliNail Team February 23, 2026 15 min read Salon Owner

An EIN (Employer Identification Number) is one of the first things you need when starting a nail salon — and one of the easiest to get. It's free, takes about 5 minutes online, and you get your number immediately.

Yet many new salon owners either skip this step, delay it, or don't understand when they actually need one. Some use their Social Security Number for everything — exposing themselves to identity theft. Others apply for the wrong type of entity and have to start over.

This guide explains exactly what an EIN is, who needs one, how to apply (with a step-by-step walkthrough), and the common mistakes that trip up nail salon owners.

What Is an EIN?

An EIN (Employer Identification Number) is a unique 9-digit number assigned by the IRS to identify your business for tax purposes. Think of it as a Social Security Number for your nail salon.

Your EIN is formatted as XX-XXXXXXX (e.g., 12-3456789) and is used for:

EIN vs. SSN vs. ITIN:

Identifier Who Gets It Format Used For
EIN Businesses XX-XXXXXXX Business taxes, hiring, banking, permits
SSN U.S. citizens and permanent residents XXX-XX-XXXX Personal taxes, employment, credit
ITIN Individuals without an SSN (non-residents, etc.) 9XX-XX-XXXX Personal tax filing only

Tip: Even if you're a sole proprietor with no employees, getting an EIN protects your personal SSN. Every time you give a vendor, bank, or client your SSN instead of an EIN, you increase your risk of identity theft.

Do You Need an EIN for Your Nail Salon?

You MUST have an EIN if:

You SHOULD get an EIN even if not required:

Bottom line: If you're opening a nail salon, you need an EIN. Whether you're an LLC with 10 employees or a sole proprietor with no employees, an EIN is the professional, secure way to identify your business.

How to Apply for an EIN — Step by Step

The fastest way to get an EIN is online through the IRS website. It's free, takes about 5 minutes, and you receive your EIN immediately upon completion.

Method 1: Online (Recommended — Instant)

1. Go to IRS.gov/EIN — Navigate to the IRS EIN Assistant at https://www.irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-online. Click 'Apply Online Now.'

2. Select your entity type — For most nail salons, you'll select one of these: • Sole Proprietorship — If you operate as an individual with no formal business entity. • Limited Liability Company (LLC) — If you've registered an LLC with your state (most common for nail salons). • Corporation — If you've incorporated (S-Corp or C-Corp). • Partnership — If you co-own the salon with one or more partners.

3. Answer the reason for applying — Select 'Started a new business' if you're opening a new salon. Other options include 'Hired employees,' 'Created a trust,' or 'Banking purposes.' For a new nail salon, 'Started a new business' is the correct choice.

4. Enter the responsible party information — The 'responsible party' is the individual who controls or manages the entity. For most nail salons, this is the owner. You'll enter your name, SSN or ITIN, address, and role (owner, member, etc.). Note: Only individuals with an SSN or ITIN can apply online — not other businesses or entities.

5. Enter your business details — • Legal name of the business (must match your LLC registration exactly). • Trade name / DBA (if different from legal name). • Business address. • State where the business is located. • Date the business started (or will start).

6. Select your business activity — Choose 'Other' and type 'Nail Salon' or 'Beauty Salon.' The IRS uses NAICS code 812113 (Nail Salons) for classification purposes.

7. Enter the expected number of employees — If you plan to hire employees within the next 12 months, enter the expected count. If you're a sole proprietor with no employees, enter 0. This determines which tax forms the IRS will expect you to file.

8. Receive your EIN immediately — After completing the application, your EIN is displayed on screen. Download or print the confirmation letter (CP 575). The IRS will also mail a physical confirmation letter to your business address within 4-6 weeks.

Method 2: By Fax (4 business days)

Complete IRS Form SS-4 and fax it to the appropriate IRS fax number based on your location. Domestic applicants fax to (855) 641-6935. You'll receive your EIN by return fax within 4 business days.

Method 3: By Mail (4-6 weeks)

Complete IRS Form SS-4 and mail it to: Internal Revenue Service, Attn: EIN Operation, Cincinnati, OH 45999. You'll receive your EIN by mail within 4-6 weeks. This is the slowest method — only use it if you cannot apply online or by fax.

Method 4: By Phone — International Only

If you're applying from outside the United States, call (267) 941-1099 (not toll-free) between 6:00 AM – 11:00 PM Eastern Time, Monday through Friday. You'll receive your EIN during the call.

Application Methods Comparison:

Method Cost Processing Time Availability
Online (IRS.gov) Free Instant Monday-Friday, 7am-10pm ET
Fax (Form SS-4) Free 4 business days Anytime (24/7 fax)
Mail (Form SS-4) Free 4-6 weeks Anytime
Phone (international only) Free Immediate (during call) Mon-Fri, 6am-11pm ET

Warning: The IRS EIN online application is ONLY available Monday through Friday, 7:00 AM to 10:00 PM Eastern Time. If you try outside these hours, the system will be unavailable. Plan accordingly.

What to Do After You Get Your EIN

1. Save your EIN confirmation letter (CP 575) — Download the PDF immediately and save it in multiple locations (cloud storage, email to yourself, print a hard copy). This is the official document proving your EIN. If you lose it, you can call the IRS Business & Specialty Tax Line at (800) 829-4933 to retrieve it, but it's much easier to just save it.

2. Open a business bank account — Bring your EIN confirmation letter, LLC documents, government ID, and initial deposit to your bank. Never mix personal and business finances — a separate business account is essential for tax compliance, liability protection, and professional credibility.

3. Register with your state tax authority — Use your EIN to register for state taxes — income tax, sales tax, and employment taxes (if applicable). Most states allow online registration through the Department of Revenue website.

4. Apply for business licenses and permits — Your EIN is required on most business license applications at the city, county, and state level. See our guide: 'How to Apply for a Business License — All 50 States Guide.'

5. Set up payroll (if you have employees) — Register with the IRS for employment taxes using your EIN. You'll need to file Form 941 (quarterly employment tax return) and issue W-2s at year end. Consider using payroll software or a payroll service.

6. Set up your merchant account — Credit card processors require your EIN to set up a merchant account for accepting payments. Your EIN is also needed for POS systems like SimpliNail.

7. Complete W-9 forms for vendors — Vendors will ask for a W-9 form before doing business with you. Your EIN goes in Box 1 and 2. Never put your SSN on a vendor W-9 — always use your EIN.

Tip: Save your EIN in a password manager alongside your other business credentials. You'll need it frequently — for tax filings, bank applications, vendor forms, and license renewals.

When You Need a New EIN (And When You Don't)

You NEED a new EIN if:

You do NOT need a new EIN if:

Warning: If you buy an existing nail salon, you cannot use the previous owner's EIN. You must apply for a new EIN for your entity. The seller's EIN remains associated with their tax history — not yours.

7 Common EIN Mistakes Nail Salon Owners Make

1. Using your SSN instead of an EIN. Every vendor form, bank application, and license that asks for a tax ID should get your EIN — not your SSN. Using your SSN exposes you to identity theft. If your salon is ever hacked, sued, or documents are leaked, your SSN is compromised.

2. Paying for an EIN application. The IRS does NOT charge for EINs. If a website is asking you to pay $49, $79, or $149 for an EIN application, it's a third-party service that files on your behalf and adds a markup. Go directly to IRS.gov — it's free.

3. Applying for the wrong entity type. If you're an LLC but select 'Sole Proprietorship' on the EIN application, the IRS will classify your business incorrectly. This causes problems with tax filings and may require you to apply for a new EIN. Match the entity type to your actual registration with the Secretary of State.

4. Not saving the confirmation letter. The IRS confirmation letter (CP 575) is only displayed once during the online application. If you close the browser without downloading it, you'll need to call the IRS to get a verification letter (Form 147C), which can take days. Always download and save immediately.

5. Using the old owner's EIN after purchasing a salon. When you buy an existing nail salon, you must get your own EIN. The seller's EIN is tied to their entity and tax history. Using it will cause tax filing conflicts and potential IRS notices.

6. Applying multiple times. The IRS limits online EIN applications to one per responsible party per day. If you submit multiple applications by accident, you'll end up with multiple EINs for the same entity, creating confusion and potential tax issues. If this happens, call the IRS to cancel the duplicate(s).

7. Not updating the IRS when your business structure changes. If you start as a sole proprietor and later form an LLC, you need a new EIN. Many salon owners forget this step and continue using their old EIN, which causes mismatches on tax returns.

EIN and Business Structure: What Nail Salon Owners Need to Know

Business Structure EIN Required? Tax Filing Liability Protection Best For
Sole Proprietorship Recommended (not required if no employees) Schedule C on personal return No — personal assets at risk Single owner, testing the waters
Single-Member LLC Yes Schedule C (default) or elect S-Corp Yes — personal assets protected Most common for nail salons
Multi-Member LLC Yes Form 1065 (partnership return) Yes Co-owned salons
S-Corporation Yes Form 1120-S Yes Salons earning $80K+ net (tax savings on self-employment tax)
C-Corporation Yes Form 1120 Yes Large salon chains (rare for single locations)

The most popular structure for nail salons is a Single-Member LLC. It provides personal liability protection (separating your business assets from your personal assets), pass-through taxation (no double taxation), and is relatively simple and inexpensive to set up ($50-$500 depending on your state).

Tip: Once your salon's net income exceeds approximately $60,000-$80,000 per year, consider electing S-Corporation status for your LLC. This can save you thousands in self-employment taxes by allowing you to pay yourself a reasonable salary and take the remaining profit as distributions (which aren't subject to the 15.3% self-employment tax). Consult a CPA before making this election.

State Tax Registration: What Else You Need Besides an EIN

Your federal EIN is just the beginning. Most states require additional tax registrations that use your EIN as an identifier.

State tax registrations you may need:

1. State Tax ID Number — Many states issue their own tax identification number in addition to your federal EIN. You'll use this for state income tax filings and other state obligations.

2. Sales Tax Permit / Seller's Permit — Required if your state taxes nail services or if you sell retail products. Nail services are taxable in most states, but rules vary. Apply through your state's Department of Revenue.

3. State Employer Withholding Account — If you have employees, you must register to withhold state income tax from their paychecks. This is separate from your federal employment taxes.

4. State Unemployment Insurance (SUI) — Required in all states if you have employees. You'll receive a state employer account number for filing unemployment insurance taxes.

States with no income tax (no state income tax withholding needed):

Note: Even in no-income-tax states, you still need sales tax permits and unemployment insurance registration if applicable.

Frequently Asked Questions

Q: Do I need an EIN for my nail salon?

A: If you have employees or operate as an LLC, corporation, or partnership — yes, an EIN is required by the IRS. Even if you're a sole proprietor with no employees, you should get an EIN to protect your SSN, open a business bank account, and build business credit. It's free and takes 5 minutes.

Q: How much does it cost to get an EIN?

A: An EIN is completely free when you apply directly through the IRS at IRS.gov. Beware of third-party websites that charge $49-$149 to file on your behalf — they are filing the same free IRS form and adding a markup. Always apply directly through the IRS.

Q: How long does it take to get an EIN?

A: Online: Instant (you receive your EIN immediately upon completing the application). By fax: 4 business days. By mail: 4-6 weeks. The online application is available Monday-Friday, 7am-10pm Eastern Time.

Q: Can I use my SSN instead of an EIN?

A: Sole proprietors with no employees can legally use their SSN for business purposes, but it's not recommended. Using your SSN on vendor forms, bank applications, and license paperwork increases your risk of identity theft. Get an EIN instead — it's free and provides a layer of protection for your personal information.

Q: What if I lose my EIN confirmation letter?

A: Call the IRS Business & Specialty Tax Line at (800) 829-4933, Monday-Friday, 7am-7pm local time. The IRS can look up your EIN and send you a verification letter (Form 147C). You can also find your EIN on previously filed tax returns, bank account opening documents, or your state's business registration records.

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

A: No. Changing your business name (DBA) does not require a new EIN as long as your business structure stays the same. You do need to notify the IRS of the name change by filing your next tax return with the new name, or by writing to the IRS at the address where you file your return.

Q: Do I need a separate EIN for each salon location?

A: Not necessarily. If all locations are under the same LLC or corporation, you use the same EIN. But if each location is a separate legal entity (separate LLCs), each entity needs its own EIN. Most multi-location salon owners create separate LLCs for liability protection, which means separate EINs.

Q: What is Form SS-4?

A: Form SS-4 is the IRS form used to apply for an EIN by fax or mail. It's the paper equivalent of the online application. You can download it from IRS.gov. The online application is faster and easier — Form SS-4 is only needed if you can't apply online.
