How to Get an EIN for Your Business 

If you've recently launched your own business — or are gearing up to — getting an Employer Identification Number (EIN) is one of your most important steps. 

Without an EIN, many doors remain closed to you. Opening a business bank account, filing taxes, hiring employees, or even getting certain licenses often aren’t possible without this critical identifier. 

Step one: Don’t freak out. The process of getting one is far from intimidating. With the right guide, you can have your EIN in a matter of minutes — or at the very most, a couple of weeks. Here’s the “what,” “why,” and, most importantly, “how” of getting an EIN for your business. 

What Is an EIN? 

Every citizen has a social security number. Every business has one, too. That’s your EIN. But it’s for your business, and it’s not attached to any of your personal information.

The IRS issues it, and usually comes in this format: XX-XXXXXXX. Think of it as a way to identify your business for tax purposes, much like your personal SSN identifies you. It’s Point A for you and also for the government. 

They need to have that number to track what you do to make sure your taxes are on time, correct, and that you can’t be connected to illicit activities.

How to Get an EIN for Your Business and Why You Need It 

Whether you're a solo entrepreneur with no employees or a small business looking to expand, you need to know how to get an EIN. Not only is it mandatory, but it simplifies a lot of processes. Here's where it comes into play:

• Tax Filing: The IRS uses your EIN to track your business taxes.

• Hiring Employees: Before onboarding your first hire, you’re legally required to have an EIN. 

• Opening a Business Bank Account: Many (pretty much all) banks request an EIN for account setup. 

• Building Business Credit: Having an EIN helps establish your business as a unique entity, paving the way for better funding opportunities. 

Even if you’re a sole proprietor, getting an EIN could save you from sharing your SSN widely, offering extra security. 

Step-by-Step Guide to Getting an EIN – the Tax ID for Business

Now for the part you’ve likely come here for. Here’s exactly how to secure a tax ID for your business. 

The process is straightforward, but making sure you follow the steps correctly will save you both time and hassle. Here’s an expanded breakdown to walk you through the process. 

Step 1. Gather the Necessary Information 

Preparation is key when applying for an EIN. Before starting your application, you’ll need to have all the required details readily available. Here’s exactly what you’ll need to have on hand: 

• Business Name - Register the business name. It should match the name you use on your EIN application. Consistency here will avoid processing delays. 

• Business Address - This needs to be the business’s physical location or mailing address. Double-check that your address is accurate, as it’s where official IRS correspondence will be sent in the future. 

• Business Structure - Define your business entity type — whether it's a Limited Liability Company (LLC), Corporation, Sole Proprietorship, Partnership, Non-Profit, or another type. Each structure comes with its own set of tax responsibilities. A good move is to discuss this with your business attorney and accountant to determine which makes the most sense for your company. 

• Reason for Applying - The IRS will ask why you’re applying for an EIN. Some common reasons include starting a new business, hiring employees, or forming a trust or estate. Be clear about your selection, as it could influence your filing process. 

• Principal Officer or Responsible Party Details - You’ll need the name and Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) of the person who is considered the principal officer or responsible party for the business. This is usually the individual who owns or controls the business. 

Step 2. Choose Your Application Method 

The IRS provides various ways to apply for an EIN to cater to different needs. Each method has its own timeline and requirements, so it’s worth picking the one that aligns with your preferences and urgency. 

Option 1. Apply Online 

• The online application through the IRS EIN Assistant (accessible at irs.gov) is by far the most convenient and fastest way to apply. 

• This option is available to individuals and entities with a valid SSN or ITIN, and the business must be physically located in the U.S. or U.S. territories. 

• By following the step-by-step prompts, you can complete the process in about 10–15 minutes, and you’ll receive your EIN immediately upon submission. Note that this option is only accessible during specific hours, typically Monday through Friday. 

Option 2. Apply by Mail 

• If online isn’t an option, or paperwork is more your style, you can fill out Form SS-4 (Application for Employer Identification Number) and mail it to the IRS. 

• The processing time for mailed applications ranges from 4 to 8 weeks, depending on how busy the IRS is. Keep in mind that any errors on the form can delay processing even further, so take extra care to ensure the details are accurate. 

Option 3. Apply by Fax 

• For a quicker alternative to mailing, fax your completed Form SS-4 to the IRS. 

• Your application will typically be processed within 4 business days. Remember to include a return fax number so the IRS can respond directly to you with your EIN. 

Option 4. Apply by Phone (for Foreign Applicants) 

• For applicants outside the U.S., the IRS offers the option to apply by phone. Start by completing Form SS-4 to ensure you have all the required information. 

• Call the IRS at +1-267-941-1099. While the call itself may take some time, the benefit is that you’ll often receive your EIN during the call itself, provided everything is in order. 

Step 3. Follow the Application Process Carefully 

No matter which method you use, be accurate. Take your time. 

Small errors can lead to delays, which is not the best way to get a new company going in the right direction. Double-check your information, especially the relevant SSNs and ITINs, the spelling of business names, and other key details, before submitting your application. 

Step 4. Save and Secure Your EIN

Once you’ve successfully navigated the IRS’s hoops and received your EIN, make it a priority to keep it safe and accessible. You’ll need it regularly for tasks such as filing taxes, applying for loans, opening business bank accounts, or expanding your operations. 

A misplaced EIN can cause delays in your business processes, so consider storing it digitally in a secure document folder, as well as keeping a physical copy with other critical business records.

How to Get an EIN – Breaking Down the EIN Application Process 

Here are some pros and cons you may run into during the EIN application process while using the above methods:

Online Method 

• Pros: Quick and efficient; immediate EIN issuance.

• Cons: These guys don’t work 24/7. It’s not an eCommerce business. Keep that in mind when filing. 

Mail Method 

• Pros: Works for everyone, regardless of internet access. 

• Cons: Excruciatingly slow (up to 8 weeks). 

Fax Method 

• Pros: Faster than mail; less than a week turnaround. 

• Cons: Requires access to a fax machine or software. 

Phone Method (Foreign Applicants Only) 

• Pros: Virtually instantaneous. 

• Cons: Limited to those outside the U.S. 

Common Mistakes to Avoid 

Making mistakes during your EIN application process can delay everything. Here’s what to keep in mind so things flow smoothly:

• Incorrect Business Name: The name provided should match your registration paperwork exactly. A mismatch could lead to significant headaches.

• Selecting the Wrong Business Structure: Choose the correct legal structure during the application. Switching later can be a hassle. 

• Multiple EIN Applications for the Same Entity: Applying for multiple EINs can confuse tax reporting processes. Generally, one EIN suffices unless massive restructuring happens. 

• Not Saving Your EIN Details: Losing your EIN immediately after issuance is far from ideal. While you can request a replacement from the IRS, it’s a process that’ll waste valuable time. 

Other Avenues for Establishing a Business and an EIN

We get it. This is a lot. And you may find yourself struggling to find the time to get it all done. Starting a business and obtaining a tax ID can feel overwhelming, especially if you're navigating these steps for the first time. 

The good news is, you don’t have to do it all alone. Several options are available to help you establish your business and secure your EIN, whether you’re looking for professional guidance or aiming to save time and hassle. 

Below, we detail these possibilities so you can choose the best approach for your unique situation.

Option 1: Hire a Business Attorney 

Hiring a business attorney can be an excellent option for those who prefer a hands-on professional to guide them. Attorneys bring extensive knowledge of business laws and regulations and can offer tailored advice to ensure your EIN application is accurate and compliant. 

This route is especially helpful if you have a complex business structure, such as partnerships, multi-member LLCs, parent/subsidiary companies, or if you foresee needing legal advice for contracts, trademarks, or resolving other corporate matters. 

While this option may cost more than doing it yourself, the peace of mind and personalized support can often make it worth the investment.

Option 2: Use a Business Formation Service 

Business formation services are designed to make the entire process of starting a business easier. These companies can assist with applying for your EIN, registering your business, and filing other required documents, such as Articles of Incorporation or LLC formation paperwork. 

Many of these services are relatively affordable compared to hiring an attorney, and they often offer tiered pricing, allowing you to pay for only the services you need. 

Some even provide expedited processing to ensure your EIN is issued quicker than the standard timeframe. This option is great for small business owners looking for convenience on a budget.

Legalzoom is probably the most widely known. 

Option 3: Work With a CPA

A certified public accountant (CPA) is another useful option, particularly during the foundational stages of your business. A trusted CPA can help you register your EIN as part of their services while ensuring your business complies with local, state, and federal tax requirements. 

This is particularly helpful if you need tax advice, bookkeeping, or organizational help. While a CPA can be slightly more expensive than using an online service, they provide valuable expertise that goes beyond simple EIN creation, such as financial planning and tax filing.

Option 4: Leverage a Registered Agent Service 

When forming your business, some states require you to designate a registered agent — a person or company authorized to receive legal documents on behalf of your business. 

Many registered agent services offer assistance with obtaining an EIN as part of their package. This option can be convenient if you're already using a registered agent and want to streamline the setup process by consolidating your business formation needs.

Northwest Registered Agent is the most common name currently in the space.

Option 5: State Government Resources or Workshops

Depending on where you're located, some states offer free or low-cost workshops, resources, or consultations to help new business owners file for an EIN and complete other startup tasks. 

These can often be a great starting point for entrepreneurs who feel overwhelmed by the process but aren't yet ready to hire professional help. State Small Business Development Centers (SBDCs), for example, can be a valuable source of guidance.

Which Option Is Right for You? 

The choice depends on your individual needs, budget, and business complexity. If you’re confident and have the time, applying for an EIN yourself can save you money. 

On the other hand, if you’d rather focus on growing your business and leave the setup process to the pros, hiring a business attorney or CPA or using a formation service might be a better fit. Whatever path you choose, know there’s support available every step of the way to help you build your dream business.

Take the Next Step for Your Business 

Starting your business is an exciting yet challenging journey, and the EIN application process is one of the first steps. The path you choose — whether it's handling the process yourself, leveraging professional services, or utilizing state resources — depends entirely on your circumstances, goals, and priorities. 

There’s no right or wrong way to approach this as long as you stay informed and make decisions that align with your vision. 

Now that you know how to get an EIN, you can take each step confidently, aware, and comfortable with the fact that you’re building the foundation for something meaningful. You can turn your business aspirations into a thriving reality with dedication, careful planning, and the right support.
