ein for poland

Polish entrepreneurs can get a US EIN by submitting IRS Form SS-4 by fax. Your Polish passport number replaces the SSN requirement on Line 7b. The IRS online tool is blocked for applicants without an SSN, so the fax method is your path. ein.so prepares your SS-4, faxes it to the IRS at 855-215-1627, and delivers your EIN by email. Standard processing costs $49 (4-7 business days). Express costs $97 (2-3 business days).

Poland is the European Union's sixth-largest economy, with a GDP of $688 billion and a population of 38 million. Polish founders increasingly build for the US market: software houses and IT contractors from one of Europe's strongest tech talent pools, Amazon and Shopify sellers shipping consumer goods, content creators, and consultants invoicing American clients in dollars. To operate a US business entity, every one of them needs a US EIN. This guide explains how Polish applicants get an EIN without an SSN, how to format a Polish address on Form SS-4, and how to set up US banking and payments after approval.

Use Cases

Why Do Polish Entrepreneurs Need a US EIN?

Polish entrepreneurs need a US EIN because a US LLC cannot open a bank account, accept US payments, or file US taxes without one. The EIN is the 9-digit federal tax ID that links your Polish-owned company to the US financial system.

Poland's IT sector and its export-driven manufacturing and consumer-goods businesses push founders toward the US, where customers, payment processors, and capital concentrate. Here are the most common reasons Polish applicants come to ein.so.

IT Contractors and Software Houses

Polish developers and software houses form US LLCs to bill American clients in dollars, integrate Stripe on a US entity, and present a US business identity on enterprise contracts. The EIN is required before any of this works.

E-commerce and Amazon.com

Sellers expanding to Amazon.com need a US tax ID for the seller tax interview. Polish brands use a US LLC and EIN to reach American buyers and use FBA warehouses inside the United States.

Freelancers and JDG Owners

Polish freelancers and JDG (jednoosobowa dzialalnosc gospodarcza) owners serving US clients form a US LLC to invoice in USD, avoid unfavorable PayPal conversion, and look credible to American buyers.

Content Creators and Digital Products

YouTubers, course creators, and SaaS founders use a US entity and EIN to access US-based payout rails and platforms that reward a verified US business presence.

Step-by-Step

How Do Polish Citizens Apply for a US EIN?

Polish citizens submit IRS Form SS-4 by fax to 855-215-1627, using a Polish passport number in place of an SSN. The IRS online tool requires an SSN, so the fax method is the only viable path. The IRS issues most correctly filed EINs within 4-7 business days.

1

Form Your US LLC

Most Polish founders register an LLC in Wyoming, Delaware, or New Mexico through a registered agent. This gives you a US business address and a legal entity to attach the EIN to. You form the LLC entirely online from Poland.
2

Gather Your Documents

You need your Polish passport (valid and unexpired), your LLC formation details (name, state, formation date), and your Polish address. No NIP, REGON, or Polish registration is required for the EIN.
3

Complete Form SS-4

Enter your US LLC name on Line 1, your Polish address on Line 4, your full name as responsible party on Line 7a, and your Polish passport number on Line 7b. ein.so completes this for you to prevent errors.
4

Submit by Fax and Receive Your EIN

The SS-4 is faxed to the IRS at 855-215-1627. Standard delivery is 4-7 business days; Express is 2-3 business days. The IRS returns your EIN assignment letter (CP 575).

Poland-Specific SS-4 Field Guide

SS-4 FieldPolish Entry
Line 1 (Legal name)Your US LLC name
Line 4 (Address)Your Polish address (ulica, kod pocztowy, miasto)
Line 7a (Responsible party)Your full name as on your passport
Line 7b (SSN/ITIN/EIN)Your Polish passport number
Line 10 (Reason)Started new business
Line 16 (Principal activity)E.g., "software," "e-commerce," "consulting"

The most common Polish rejection cause is address formatting. The 5-digit kod pocztowy (format XX-XXX) and the ulica/numer/miasto fields do not map cleanly to the SS-4 layout, and the IRS silently rejects malformed international addresses. ein.so reformats Polish addresses to an IRS-accepted style. See the full SS-4 form guide and the complete EIN application process. You apply through the EIN without SSN path.

Cost & Timing

How Much Does an EIN Cost for a Polish Applicant?

The IRS charges $0 for an EIN. ein.so charges $49 for Standard service (4-7 business days) or $97 for Express service (2-3 business days). The fee covers SS-4 preparation, Polish address reformatting, fax submission, and email delivery of your EIN.

Polish applicants face two practical problems with the DIY route. First, the IRS online tool rejects anyone without an SSN, so it is not an option. Second, the phone method to 267-941-1099 forces an international call from Poland during US business hours, with long holds and the risk of a transcription error on a Polish name. The fax route avoids both, and ein.so handles the fax for you.

ein.so also offers an ITIN service for Polish individuals who need a personal taxpayer ID: $197 Standard or $297 Express. An ITIN is separate from an EIN and is not required to form a US LLC. Compare the full EIN cost breakdown and EIN processing time before you choose.

Banking & Payments

How Do Polish Entrepreneurs Use Their EIN for US Banking and Payments?

Polish entrepreneurs use their EIN to open a US business bank account and connect US payment processors, which together give a Polish-owned LLC full access to the dollar economy. Mercury and Relay approve most Polish LLC owners remotely within a few business days.

US Business Bank Account

Mercury, Relay, and Wise accept Polish LLC owners with an EIN and a passport. You receive US account and routing numbers for ACH and domestic wires. See EIN for a bank account.

Stripe on a US Entity

A US LLC and EIN let you bill US customers as a US business, simplify USD settlement, and access features tied to a US entity. See EIN for Stripe.

PayPal Business (US)

A US PayPal Business account linked to your EIN holds USD without forced conversion to zloty, which improves margins on US sales. See EIN for PayPal.

Wise and SEPA Transfers

Many Polish founders use Wise to move funds between a US account and a Polish account at the mid-market rate, then convert to zloty only when the rate is favorable. See EIN for Payoneer for an alternative.

Together, a US LLC, an EIN, and a US bank account let you invoice American clients in dollars, accept card payments through Stripe, and repatriate profits to your Polish bank when the PLN/USD rate works in your favor.

Tax Considerations

What Should Polish Entrepreneurs Know About US and Polish Taxes?

A single-member US LLC owned by a Polish resident is usually a disregarded entity for US federal income tax, meaning the LLC itself pays no US federal income tax on non-US-sourced income. You still carry US information-filing duties, and you continue to declare income in Poland.

US Filing: Form 5472 + 1120

A foreign-owned single-member US LLC must file Form 5472 with a pro-forma Form 1120 each year. The penalty for not filing is $25,000. This is an information return, not necessarily a tax bill.

US-Poland Tax Matters

The United States and Poland have an income tax treaty framework that addresses double taxation. Treaty treatment depends on your facts. Confirm withholding and relief with a US CPA and a Polish doradca podatkowy before you rely on any rate.

Polish Reporting

Polish residents generally must report foreign company interests and foreign accounts to KAS. Confirm your reporting duties for a foreign-held US LLC with a Polish doradca podatkowy.

BOI Report to FinCEN

Most US LLCs report beneficial ownership to FinCEN. Review the BOI filing rules to avoid penalties. The BOI report is free at fincen.gov/boi.

ein.so handles the EIN application and does not provide tax advice. Work with a Polish doradca podatkowy and a US CPA familiar with non-resident matters, and confirm every tax specific with a CPA. Your EIN is the starting point for US tax compliance. See our EIN without SSN guide and EIN for non-residents.

Common Mistakes

What Mistakes Do Polish Applicants Make on Form SS-4?

Polish applicants most often fail because of a malformed address, a blank Line 7b, or a wrong entity type. Each error causes a silent IRS rejection with no notification, so you wait weeks before realizing the application never processed.

Avoid these four SS-4 errors

  1. Leaving Line 7b blank because you have no SSN — enter your Polish passport number instead.
  2. Writing the kod pocztowy in the wrong field so the IRS reads the address as malformed.
  3. Selecting the wrong entity type on Line 9a for a single-member LLC.
  4. Using a Polish phone format the IRS fax cover sheet cannot parse.

ein.so checks each of these before submission. We confirm Line 7b carries your passport number, reformat the kod pocztowy and ulica into the IRS layout, match the entity type to your LLC, and submit a clean fax to 855-215-1627. If the IRS rejects a filing, we resubmit at no extra charge. Start your application on the apply page and review the EIN processing time page to set expectations.
