State Guide
EIN in Iowa (IA)
How to get an EIN for your Iowa business or Iowa LLC. The EIN is a federal number from the IRS, identical in every state. Non-residents apply by fax with a passport. ein.so files it for $49.
Getting an EIN in Iowa follows the same federal IRS process as every other state. The EIN is a federal number, not state-specific, and it is free from the IRS. You file Form SS-4. US residents apply online with an SSN. Non-residents fax Form SS-4 to 855-215-1627 using a passport number on Line 7b. ein.so files it for $49 (4-7 business days) or $97 (2-3 business days).
An EIN (Employer Identification Number) is a 9-digit federal tax ID formatted as XX-XXXXXXX. The IRS issues it. Iowa does not. Whether your business sits in Des Moines, Cedar Rapids, or Davenport, the EIN application is identical to one filed in California or New York. This guide explains how Iowa business owners and non-resident owners of an Iowa LLC get an EIN, how the federal EIN differs from an Iowa state tax ID, and what to do after the EIN arrives.

Federal vs State
Is an Iowa EIN Different From a Federal EIN?
No. An Iowa EIN is the same as a federal EIN because the IRS issues one EIN that works in every state. Iowa does not create its own EIN. Your 9-digit number stays the same whether you operate in Iowa or relocate to another state.
Two different identifiers confuse many Iowa business owners. The federal EIN comes from the IRS for federal tax purposes. The Iowa state tax ID comes from the Iowa Department of Revenue for state sales tax and employer withholding. They serve separate functions and you may need both.
| Identifier | Issued By | Used For |
|---|---|---|
| Federal EIN | IRS | Federal taxes, banking, Form SS-4 filing |
| Iowa state tax ID | Iowa Department of Revenue | Iowa sales tax, employer withholding |
Your EIN does not replace Iowa state registration. If you sell taxable goods or hire employees in Iowa, register separately with the Department of Revenue. Confirm your exact obligations with the state or a CPA, since registration needs depend on your activity. See state tax ID for more detail on the distinction.
How to Apply
How Do You Get an EIN in Iowa?
You get an EIN in Iowa by filing IRS Form SS-4 in one of four ways. The online tool is instant but needs an SSN. Fax to 855-215-1627 takes 4-7 business days. Phone suits international applicants. Mail takes 4 or more weeks. The method depends on whether you have an SSN.
| Method | Speed | SSN Required | Cost |
|---|---|---|---|
| Online | Instant | Yes | $0 |
| Fax | 4-7 days | No | $0 / $49 via ein.so |
| Phone | Same day | No | $0 |
| 4+ weeks | No | $0 |
The process is identical regardless of state. Iowa adds no extra EIN steps. See how to get an EIN for complete instructions and the SS-4 form guide for line-by-line help.

Non-Residents
Can a Non-US Resident Get an EIN for an Iowa LLC?
Yes. A non-US resident gets an EIN for an Iowa LLC without an SSN or ITIN. You enter your passport number on Form SS-4 Line 7b instead of an SSN. The IRS online tool is blocked without an SSN, so non-residents fax Form SS-4 to 855-215-1627.
Owning an Iowa LLC as a non-resident is fully legal. The IRS does not require US presence, residency, or citizenship to assign an EIN. Many international founders pick Iowa or another state, form an LLC remotely, and apply for the EIN by fax from abroad.
| SS-4 Field | Non-Resident Entry |
|---|---|
| Line 1 (Legal name) | Your Iowa LLC name |
| Line 4 (Address) | Your foreign or US mailing address |
| Line 7a (Responsible party) | Your full name as on your passport |
| Line 7b (SSN/ITIN/EIN) | Your passport number (no SSN needed) |
| Line 10 (Reason) | Started new business |
A common rejection cause is malformed international address formatting on Line 4. The IRS silently rejects addresses it cannot parse. ein.so reformats your address to an IRS-accepted style. See EIN without SSN and EIN for non-residents for full guidance. If you also need a personal taxpayer number, ein.so files ITIN applications for $197 (Standard) or $297 (Express).
Cost & Timing
How Much Does an EIN in Iowa Cost?
The IRS charges $0 for an EIN in Iowa or any state. The number itself is always free. You pay only for optional filing assistance or for forming your Iowa entity. ein.so charges $49 Standard or $97 Express to file Form SS-4 for non-residents who cannot use the free online tool.
The online IRS tool is the cheapest path for anyone with an SSN, because it issues the EIN instantly at no cost. Non-residents without an SSN must use fax, which is slower and error-prone for first-timers. That is the gap ein.so closes.
| Item | Cost | Notes |
|---|---|---|
| EIN from the IRS | $0 | Free in every state |
| Iowa LLC filing fee | State fee | Confirm current amount with the Iowa Secretary of State |
| ein.so Standard EIN | $49 | 4-7 business days |
| ein.so Express EIN | $97 | 2-3 business days |
| ein.so ITIN (Standard) | $197 | Personal taxpayer number |
