What is an EIN (Employer Identification Number)?

Updated 2026-05-28

An Employer Identification Number (EIN) is a nine-digit number issued by the Internal Revenue Service (IRS) to business entities operating in the United States. It is used to identify a business for federal tax purposes, much like a Social Security Number (SSN) identifies an individual.

Vacation rental businesses structured as corporations, partnerships, or multi-member LLCs are typically required to obtain an EIN. Sole proprietors may also need one if they hire employees or are required to file certain types of federal tax returns.

How it works

A business owner can apply for an EIN for free directly from the IRS, most commonly through an online application on the IRS website. This method is the fastest, often providing the number immediately upon completion of the form.

Applications can also be submitted by mail or fax. Once assigned, the EIN must be used on all required federal tax forms, including annual income tax returns, employment tax returns, and forms for non-employee compensation.

The number is also necessary for essential business activities like opening a business bank account and applying for local business licenses.

Why it matters

For vacation rental operators, an EIN is fundamental for establishing the business as a distinct legal and financial entity. It allows hosts to formally separate business and personal finances, which simplifies accounting and strengthens liability protection.

Having an EIN is a prerequisite for hiring employees, such as cleaners or administrative staff, as it's needed to manage payroll and employment taxes. Using an EIN on business documents instead of a personal Social Security Number also enhances personal data security and reinforces the professionalism of the rental operation.

Examples

  • A group of partners forms an LLC to manage a portfolio of beachfront condos. They must apply for an EIN to open a business bank account and file their partnership tax return.
  • A vacation rental owner operating as a sole proprietor decides to hire a part-time property manager as a direct employee. To handle payroll and report employment taxes to the IRS, the owner must first obtain an EIN.
  • A host wants to build business credit separately from her personal credit history. She structures her rental business as a corporation and uses its EIN to apply for a business credit card and a small business loan for renovations.
  • A property management company issues Form 1099-NEC to the freelance handymen and landscapers it paid during the year. The company's own EIN must be listed on each of these forms.

Frequently asked questions

Do I need an EIN if I run my vacation rental as a sole proprietorship?+
Generally, a sole proprietor with no employees who doesn't file excise or pension plan tax returns can use their Social Security Number for business taxes. However, obtaining an EIN is still recommended to open a business bank account and avoid using your SSN for business purposes. It becomes mandatory if you hire employees.
Is there a fee to get an Employer Identification Number?+
No, there is no cost to obtain an EIN from the IRS. The application service provided directly by the IRS is free.
Can I use my EIN as a state tax ID number?+
No, an EIN is a federal tax identification number. Most states require businesses to obtain a separate state tax ID number for state-specific tax obligations, such as remitting lodging, sales, or income taxes.
What is the difference between an EIN and a DBA?+
An EIN is a federal tax ID number used to identify a business entity. A DBA ('Doing Business As') is a registered fictitious name that allows a business to operate under a name different from its legal one. While a business may have a DBA, it still needs an EIN for tax purposes if it meets the IRS requirements.
