Can I get an EIN online?

Yes. The IRS issues EINs immediately when Form SS-4 is completed via the IRS online application. For applicants using fax or mail, processing is slower; choose online for urgent payroll setups.

An authorized officer or the responsible party named on the form must sign where signature is required. The responsible party is the person who controls management decisions, and their identification details must be accurate.

Is there a fee for an EIN?

No. The IRS does not charge a fee to issue an EIN for Form SS-4. Fees may arise from third-party services, attorney reviews, or notary services if used.

What if I entered the wrong SSN or name?

Contact the IRS to correct the record; incorrect TINs can trigger backup withholding or rejection by payers. Maintain copies of corrected filings and verification correspondence.

Can I apply without an SSN or ITIN?

Foreign applicants with no SSN/ITIN may still obtain an EIN. Follow IRS guidance for international applicants, which may require additional documentation or phone-based processing.

Is an electronic signature valid on the SS-4?

Electronic signatures are acceptable when they meet ESIGN (15 U.S.C. ch. 96) and applicable state rules (UETA) requirements: intent, consent, attribution, and reliable record retention.

What the Application for Employer Identification Number Is and when it's used

The Application for Employer Identification Number is IRS Form SS-4, used to request a federal Employer Identification Number (EIN) for a business entity, estate, trust, or other organization. An EIN identifies the taxpayer for federal tax reporting, payroll withholding, banking, and vendor enrollment. The IRS issues EINs directly and permits online, fax, or mail submissions; properly completed submissions produce a valid EIN that the business uses for Federal tax accounts, payroll filings, and information returns.

Why completing the EIN application correctly matters

A correct SS-4 prevents delays in hiring, payroll setup, and tax reporting. The EIN links to federal tax accounts and third-party payers; errors can trigger backup withholding, rejected vendor setups, or penalties under IRC rules. Accurate completion protects legal identity, ensures banking and payroll integration, and supports compliance with federal reporting obligations.

Who typically completes and uses an EIN application

Organizations and individuals who need a federal taxpayer ID complete Form SS-4; the responsible party supplies identifying information and signs where required.

New businesses and start-ups — Owners or authorized representatives who register for payroll, open business bank accounts, or elect corporate tax status.
Estates and trusts — Executors or trustees who need a distinct federal ID for fiduciary tax filings and administration.
Nonprofits and entities — Officers or authorized signers who register tax-exempt organizations or apply for payroll withholding and 501(c) processes.
