EIN and Business Bank Accounts:
What Sole Props and LLCs Actually Need

Getting an EIN is free and takes 10 minutes. Opening a business bank account is essential for LLCs. Here is exactly what you need for each structure.

Employer Identification Number (EIN)

Sole Proprietor: EIN Optional

By default, sole proprietors use their Social Security Number for all tax purposes. You do not need an EIN unless:

  • + You hire employees (EIN required)
  • + You open a solo 401(k) retirement account
  • + You want to avoid giving vendors/banks your SSN
  • + You plan to elect S-Corp status later

LLC: EIN Strongly Recommended

Single-member LLCs technically do not require an EIN unless they have employees or elect S-Corp, but you almost always want one because:

  • + Banks require it to open a business account
  • + Protects your SSN from vendors and contractors
  • + Needed if you ever hire or elect S-Corp
  • + Establishes the LLC as a separate financial identity

How to Get an EIN: Free in 10 Minutes

  1. 1Go to IRS.gov and search 'EIN online application'
  2. 2Select the correct entity type (sole proprietor or LLC)
  3. 3Enter your legal name, SSN, business name, and address
  4. 4Answer a few questions about your business
  5. 5Receive your EIN immediately on screen and by email

Warning: Many websites charge $50-$100 to "help you get an EIN." This is unnecessary. The IRS application is free and straightforward. Only use IRS.gov directly.

Business Bank Accounts

Sole Proprietor: Optional but Recommended

You are not legally required to have a separate bank account as a sole proprietor. Many people run sole prop businesses using a personal account. However, a separate account makes bookkeeping cleaner, simplifies Schedule C preparation, and looks more professional to clients.

LLC: Separate Account is Essential

Commingling personal and business funds is the single most common cause of courts piercing the LLC's corporate veil. If you use one account for everything, you may lose your liability protection in a lawsuit. Open a dedicated LLC account immediately after formation.

EIN and Banking FAQ

Do I need an EIN as a sole proprietor?
No by default. Sole proprietors with no employees can use their SSN. Get an EIN if you hire, open a solo 401(k), want to protect your SSN with vendors, or plan to elect S-Corp later. It is free from IRS.gov.
Does an LLC need a separate bank account?
Not legally required in most states, but practically essential. Commingling funds is the most common cause of courts piercing the LLC's corporate veil and eliminating your liability protection.
