To get a tax ID number, the process depends on the type of tax ID you need:
For an Individual Taxpayer Identification Number (ITIN) in the U.S.
- ITINs are for individuals who are not eligible for a Social Security Number (SSN) but need to file U.S. taxes, such as nonresident aliens and their dependents.
- You must complete IRS Form W-7, Application for IRS Individual Taxpayer Identification Number.
- Submit the Form W-7 along with your federal income tax return and original or certified documents proving your identity and foreign status (e.g., passport).
- You can apply by mailing the documents to the IRS, in person at an IRS Taxpayer Assistance Center, or through an IRS-authorized Acceptance Agent.
- The IRS typically processes ITIN applications within about seven weeks
For an Employer Identification Number (EIN) in the U.S.
- EINs are used for business entities.
- You can apply online via the IRS website and receive your EIN immediately if your business is in the U.S. or its territories.
- Alternatively, you can apply by mail, fax, or phone (for international applicants) using Form SS-4.
- Online application is the fastest method, available Monday through Friday, 7 a.m. to 10 p.m. ET
For Tax Identification Numbers in other countries (e.g., Austria,
Germany)
- In Austria, you request your tax ID (“Steuernummer”) from your local tax authority (“Finanzamt”) either in person, by mail, phone, or online through Finanzonline
- In Germany, citizens automatically receive a tax ID number, but you can request a new one online if lost
Summary
- Determine the type of tax ID you need (ITIN for individuals without SSN, EIN for businesses, or local tax ID in your country).
- For ITIN in the U.S., complete Form W-7 with tax return and documentation, then submit by mail or in person.
- For EIN in the U.S., apply online for immediate issuance or use Form SS-4 by mail/fax/phone.
- For other countries, contact your local tax authority to request the tax ID.
