Does a Sole Proprietor Need an EIN? FAQs, Expert Tips, and Examples

Starting a business as a sole proprietor comes with its fair share of questions, one of the most common being:

“Does a Sole Proprietor Need an EIN?”

While an EIN (Employer Identification Number) is often associated with larger businesses, it can also benefit sole proprietors in many ways.

In this guide, we’ll break down when an EIN is required, why you might want one even if it’s optional, and how doola can simplify the EIN registration process for you.

What Is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number issued by the IRS to identify businesses for tax purposes. Think of it as a Social Security Number (SSN), but specifically for business entities.

While primarily used for hiring employees, filing taxes, and opening a business bank account, an EIN can also provide added security and legitimacy for sole proprietors.

Let’s now answer your question: Does a Sole Proprietor Need an EIN?

Does a Sole Proprietor Need an EIN?

According to the IRS, you typically don’t need a sole proprietorship EIN unless you have employees or are required to file specific tax returns. However, if either of these applies to you, obtaining an Employer Identification Number is a must.

Let’s explore two common scenarios to determine when an EIN is necessary.

When Is an EIN Required?

A sole proprietor must obtain an EIN if they:

• Hire employees

• Operate as an LLC (even if it’s a single-member LLC)

• Have a Keogh retirement plan

• File excise tax returns (for alcohol, tobacco, or firearms sales)

• Withhold taxes for non-resident aliens

Let’s now discuss the cases where having an EIN is not mandatory.

When Is an EIN Optional?

You may now ask: does a sole proprietor need an EIN even if it’s not legally required? It may not be a mandate in the US state you’re operating in, but obtaining one can still be beneficial.

You may choose to secure an EIN if you:

• Want to separate your business and personal finances

• Need to open a business bank account (some banks require an EIN even for sole proprietors)

• Plan to apply for business credit or loans

• Work with vendors who prefer to process payments using an EIN rather than an SSN

• Want an extra layer of security to reduce the risk of identity theft

So what it is the takeway: does a sole proprietor need an EIN after all? While it may not always be mandatory, the benefits speak for themselves.

Now, let’s explore how having an EIN can work in your favor.

Benefits of Having an EIN as a Sole Proprietor

While it’s not always legally required, obtaining an EIN can provide numerous advantages that make managing your business easier and more secure.

Here’s why securing an EIN can be a game-changer for your sole proprietorship:

1. Establishes You as a Professional Business

When you’re freelancing or running a small business, every step toward legitimacy counts. An EIN signals that you’re operating as a serious business, not just a side hustle.

This can enhance your credibility with banks, lenders, clients, and partners, making it easier to secure loans, attract high-value customers, and build long-term business relationships.

2. Simplifies Expense Tracking & Tax Deductions

Keeping personal and business finances separate is essential for smooth bookkeeping. By using an EIN for business transactions, you can easily track your expenses, maximize tax deductions, and avoid confusion when filing taxes.

So does a sole proprietor need an EIN to track expenses and save up on taxes?

Short answer: yes. Because a well-organized financial system can always help you reduce taxable income and avoid costly errors.

3. Reduces the Risk of Identity Theft

Your Social Security Number (SSN) is a key target for identity thieves.

If you frequently share your SSN with clients, vendors, or financial institutions, you increase your vulnerability to fraud.

An EIN acts as a protective layer, allowing you to conduct business transactions securely without exposing your personal information.

4. Streamlines Bookkeeping & Accounting

Handling business finances can get complicated, but having an EIN makes bookkeeping easier. It helps differentiate personal and business transactions, ensuring accurate financial records.

If you work with an accountant or use bookkeeping software, an EIN allows for a more structured approach to managing income, expenses, and tax filings.

5. Prepares You for Hiring Employees

If you plan to expand your business and bring on employees in the future, an EIN is a must. It’s required for payroll processing, tax with-holdings, and contributing to Social Security and Medicare.

Getting an EIN early on ensures you’re set up for growth without unnecessary delays.

6. Helps Avoid Tax Penalties

For sole proprietors handling both personal and business taxes, an EIN simplifies the process. It helps keep business tax filings organized and reduces the risk of errors that could lead to IRS penalties.

Filing taxes correctly and on time is crucial for maintaining a smooth-running business.

7. Makes It Easier to Open a Business Bank Account

Having a dedicated business bank account is essential for tracking income, managing expenses, and maintaining financial clarity. Now, does a sole proprietor need an EIN for opening a business bank account?

Some banks allow sole proprietors to open business accounts without an EIN, but many require one. Checking with your financial institution in advance can help prevent unnecessary hurdles.

8. Speeds Up Business Loan Applications

Thinking about applying for a business loan? Maybe you’re also wondering: does a sole proprietor need an EIN to apply for a loan?

Lenders often require an EIN as part of the loan approval process. Having one in place shows that you’re serious about your business and helps streamline loan applications.

9. Builds Business Credit

One major advantage of getting an EIN is that it allows you to establish business credit, separate from your personal credit. Using your EIN for business credit cards, loans, and financing applications helps build a financial track record, making it easier to secure funding in the future.

10. Increases Trust with Vendors & Customers

An EIN adds legitimacy to your business, which can instil confidence in vendors and customers. Some suppliers and partners prefer working with businesses that have an EIN rather than relying on a sole proprietor’s SSN, reinforcing your professionalism.

At this point, you might still be wondering: does a sole proprietor need an EIN for every business scenario? While it depends on your specific needs, having one can make financial management, banking, and future business growth much easier.

How to Apply for an EIN

Applying for an EIN is free and can be done directly through the IRS. Here’s a simple step-by-step process:

1. Check Your Eligibility: You’ll need a valid taxpayer identification number, such as an SSN or ITIN, to apply.
