How to Get an EIN in Kentucky

An Employer Identification Number, or EIN, is a nine-digit tax ID issued by the Internal Revenue Service. If you're starting a business in Kentucky, you'll almost certainly need one. Whether you're forming an LLC, corporation, partnership, or hiring employees as a sole proprietor, an EIN is how the IRS and Kentucky Department of Revenue track your business for tax purposes.

This guide walks you through the exact process of getting an EIN in Kentucky, from determining whether you need one to receiving your number. The process is straightforward and often takes just 15 to 30 minutes online.

Do You Need an EIN in Kentucky?

Not every business needs an EIN, but most do. You need an EIN if any of these apply to your Kentucky business:

  • You are forming an LLC, S-corporation, C-corporation, partnership, or other business entity that is not a sole proprietorship
  • You have employees, even one part-time employee or family member on the payroll
  • You operate a partnership, regardless of size
  • You are a sole proprietor with $600 or more in annual gross receipts and owe self-employment tax
  • Your Kentucky business has a tax liability
  • You are required to file an employee tax return or an excise tax return
  • You are establishing a Keogh plan for a self-employed individual
  • You are a nonprofit organization, charitable trust, or other tax-exempt entity

If you are a sole proprietor with no employees and under $600 in annual receipts, you can use your Social Security Number for tax purposes instead of an EIN. However, an EIN is still recommended for privacy and to separate personal finances from business finances.

What You'll Need Before You Apply

Gather these materials before you start the application process. Having everything ready will speed up your application to just 15 to 20 minutes.

Required Information

  • Business structure documents: If you formed an LLC or corporation, have your Articles of Organization or Articles of Incorporation on hand. The filing date and state where you filed will be requested.
  • Business name and address: Your Kentucky business address (not a PO box). The IRS verifies this address, so it must be valid and where you operate the business.
  • Responsible party information: The name, date of birth, and Individual Taxpayer Identification Number (ITIN) or Social Security Number of the person responsible for the business. This is typically the owner, managing member, or principal officer. You will need the ITIN/SSN on hand when you apply.
  • Business start date: When you began or plan to begin business operations.
  • Principal business activity: A description or code for your main business activity (retail, consulting, manufacturing, etc.). If you do not know the code, the IRS application will let you describe it and suggest a code.
  • Kentucky business formation information: The date you formed your business and your Certificate of Formation number if you have one (available from the Kentucky Secretary of State business search at sosbes.sos.ky.gov).

Optional but Helpful

  • Your state business registration number or certificate number
  • The number of employees you plan to hire, if applicable
  • Any existing employer tax account numbers from other states, if you operate in multiple states

Step-by-Step: How to Get Your Kentucky EIN

Step 1: Apply Online (Recommended)

The fastest way to get an EIN is to apply online through the IRS at irs.gov/ein. The online system is straightforward, takes about 15 to 30 minutes, and your EIN is issued immediately at the end of the application.

Go to the IRS EIN application page and click "Apply for an EIN Online." You will need to:

  1. Select your legal structure (sole proprietorship, LLC, corporation, partnership, etc.)
  2. Enter your responsible party's Social Security Number or ITIN and date of birth
  3. Provide your business name exactly as it appears on your Kentucky formation documents
  4. Enter your Kentucky business address
  5. Describe your principal business activity
  6. Confirm your Kentucky formation date and document type (Articles of Organization, etc.)
  7. Provide contact information (typically the owner's phone number and email)
  8. Review and submit

At the end, you will receive your nine-digit EIN on screen. Write it down immediately. You will also have the option to print a confirmation page. Save this confirmation; you will need it for Kentucky tax registration.

Step 2: Apply by Phone (Alternative)

If you prefer not to apply online, you can call the IRS Business and Specialty Tax Line at 1-800-829-4933. Have all the information listed above ready when you call. Processing time is the same as the online method, but the IRS will issue your EIN verbally over the phone. Ask the representative to email or mail you a confirmation letter.

Step 3: Apply by Mail (Slowest Option)

Complete Form SS-4 (Application for Employer Identification Number), available at irs.gov/pub/irs-pdf/fss4.pdf. Print the form and mail it to:

Internal Revenue Service
Attn: EIN Operations
Cincinnati, OH 45999

Processing time is 2 to 4 weeks by mail. If you need your EIN faster, do not use the mail option.

Step 4: Register with the Kentucky Department of Revenue

After you receive your EIN from the IRS, you must register your business with the Kentucky Department of Revenue. Most Kentucky businesses need to register for a sales tax permit and a state income tax account. Some industries require occupational licenses.

Register online at revenue.ky.gov/Business/Pages/Register-Business.aspx using your new EIN. You will create an account on MyTaxes.ky.gov and provide:

  • Your business name and address
  • Your EIN
  • Your business structure
  • The activities your business will conduct (retail, service, manufacturing, etc.)

Kentucky registration has no fee and takes about 10 to 15 minutes. You will receive a registration confirmation immediately.

Step 5: Set Up Your Payroll Account (If You Have Employees)

If you plan to hire employees, you must set up a payroll account with both the IRS and Kentucky. The IRS will send you information about this after your EIN is issued. You can also set up the account online at irs.gov.

For Kentucky payroll withholding, register with the Kentucky Department of Revenue using the same portal where you registered for sales tax. Your EIN serves as your identifier for both state and federal payroll purposes.

Timeline and Processing

Here is what to expect after you apply:

  • Online application: Your EIN is issued immediately. You can use it right away. A formal confirmation letter arrives in the mail within 5 to 10 business days.
  • Phone application: Your EIN is given to you verbally. Processing time is immediate. Ask for a confirmation to be mailed or emailed.
  • Mail application: Processing takes 2 to 4 weeks. The IRS will mail your EIN confirmation letter to the address on your Form SS-4.

Do not wait for the confirmation letter to start using your EIN. You can use it immediately for tax purposes, opening a business bank account, hiring employees, and registering with Kentucky.

Kentucky-Specific Requirements After Getting Your EIN

Getting an EIN is just one step. Kentucky has additional requirements:

Sales Tax Permit

If your business sells products or taxable services in Kentucky, you need a sales tax permit. Register for this on MyTaxes.ky.gov at the same time you register your business. Kentucky's state sales tax rate is 6 percent. You will file returns quarterly or monthly depending on your sales volume. There is no permit fee.

Occupational License Tax

Kentucky has no statewide occupational license that applies to all businesses. However, your local county or city may require an occupational license tax based on payroll or net profits. Contact your county clerk or city business licensing office to confirm. Fees vary by location.

Limited Liability Entity Tax (LLET)

If you formed an LLC or corporation, Kentucky imposes a Limited Liability Entity Tax on your business. The minimum tax is $175 per year if your Kentucky gross receipts or gross profits are $3 million or less. Businesses with higher receipts pay a sliding scale up to 0.095 percent of Kentucky gross receipts or 0.75 percent of gross profits, whichever is less.

This tax is separate from income tax and is filed annually with the Kentucky Department of Revenue. You do not need a separate application; it is tied to your EIN and business registration.

Tips for Success

  • Apply online if possible. Online applications are processed immediately and have the lowest error rate. Phone applications are second-best; mail is slowest.
  • Have your business formation documents ready. Know the exact date you formed your LLC or corporation. Have your Certificate of Formation number if available.
  • Use your business address, not a home address. The IRS verifies your address. If you use a home address, make sure it is where you actually operate the business. A PO box will not be accepted.
  • Apply before you open a business bank account. Most Kentucky banks will ask for your EIN when opening a business account. You cannot use your Social Security Number for a business bank account.
  • Register with Kentucky right after you get your EIN. Do not delay. Some Kentucky licenses and permits require proof that you have registered with the state.
  • Keep your EIN safe. Treat it like a Social Security Number. Do not post it on public websites or share it unnecessarily. Scammers sometimes target businesses by impersonating the IRS and asking for EINs.

Common Mistakes to Avoid

  • Confusing an EIN with a business license. An EIN is a federal tax ID. It is not the same as a business license from your city or county. You may need both, and they are obtained from different agencies.
  • Using your Social Security Number when you should use an EIN. Once you have an EIN, use it for all business tax purposes. Never give your SSN as a business tax ID to vendors, employees, or the government.
  • Applying multiple times. Each application generates a new EIN. If you apply twice by mistake, you will have two EINs tied to the same business. Contact the IRS to close the duplicate if this happens.
  • Waiting to apply until you hire employees. Apply for your EIN as soon as you form your business, even if you do not plan to hire anyone immediately. It is free and takes minutes online.
  • Entering the wrong business address. The IRS verifies addresses. If you enter a PO box or an address where you do not actually operate, your application may be rejected or flagged for review.
  • Forgetting to register with Kentucky. The EIN is federal only. You still need to register your business with the Kentucky Department of Revenue to pay state taxes and obtain required licenses.

What Happens After You Get Your EIN

Once you receive your EIN, expect the following:

  • The IRS will send you a confirmation letter (EIN assignment notice) within 5 to 10 business days. Keep this in your records.
  • If you checked the "employer" box on your application, the IRS will send you Form I-9 instructions and employer tax guides.
  • The IRS may send you notices about estimated tax payments or other obligations depending on your business structure.
  • You can immediately use your EIN to open a business bank account, hire employees, and file Kentucky tax returns.
  • Kentucky will use your EIN to track your sales tax, payroll withholding, and LLET payments.

Frequently Asked Questions

Can I start my business before I get my EIN?
You can form your LLC or corporation immediately by filing with the Kentucky Secretary of State. However, you should get your EIN within a few days to open a business bank account and start hiring. Do not delay applying for your EIN.

What if I make a mistake on my application?
If you discover an error after you apply, contact the IRS immediately at 1-800-829-4933. For minor errors (spelling, wrong business structure), the IRS may be able to correct it. Major errors may require a new application.

Can I get an EIN if I have not formed my business yet?
You can apply for an EIN before your LLC or corporation is officially registered with the state, but the IRS will ask for your expected business start date. It is easier to apply after you have filed your formation documents with the Kentucky Secretary of State, as the IRS will verify your information.

Do I need an EIN if I am a sole proprietor?
Not necessarily. Sole proprietors without employees can use their Social Security Number for tax purposes. However, an EIN is highly recommended to keep your personal and business finances separate and protect your privacy.

Is there a fee for an EIN?
No. The IRS does not charge for an EIN. If someone asks you to pay for an EIN application, it is a scam.
