How do I apply for an EIN?

I’m trying to set up my business legally and want to understand the EIN application process, required documents, and IRS rules.

ARTICLE SUMMARY

Answer

An EIN, or Employer Identification Number, is a federal tax ID issued by the IRS. Many businesses use an EIN for taxes, payroll, banking, and business registration. Businesses can usually apply online directly through the IRS at no cost.

The application process is generally simple, but the required information depends on the business structure. Businesses often apply for an EIN after forming an LLC or corporation and before hiring employees or opening bank accounts.

What information is needed to apply for an EIN?

Most EIN applications require:

The legal business name.
Business structure, such as LLC or corporation.
Responsible party’s name and taxpayer ID number.
Business address.
Reason for applying.
Estimated number of employees, if any.

Some businesses may also need formation documents approved by the state before applying.

The IRS assigns only one responsible party per EIN application, and the information provided must be accurate and consistent with the applicant's business and tax records. In some cases, the IRS may verify information against existing records during the application process.

How does the EIN application process work?

Many businesses apply online through the IRS website and receive an EIN immediately after approval. Applications may also be submitted by fax or mail in some situations.

After receiving the EIN, businesses often use it to:

Open business bank accounts.
Register for payroll taxes.
Apply for licenses or permits.
File federal tax returns.
Work with vendors or payment processors.

The IRS does not charge a fee for EIN applications.

What to do next…

Confirm the business structure and legal business name first.
Gather formation documents and owner information before applying.
Apply directly through the IRS to avoid unnecessary service fees.
Save the EIN confirmation notice with business records.

What to consider in your specific situation

The EIN application process may vary depending on the business structure and planned business activities.

Whether the business is an LLC, corporation, partnership, or sole proprietorship.
If employees or payroll taxes will be involved.
Whether the business has multiple owners or members.
State registration or licensing requirements connected to the EIN.
Banking, financing, or vendor onboarding needs.
Plans for future hiring, expansion, or tax elections.
