How to open a US business bank account from Poland
Every major provider accepts Polish founders, so access is not your problem. Two other things are: a foreign-exchange law that still contains a live permit mechanism keyed to which bloc your destination country belongs to, and a controlled-foreign-company regime with a named statutory home that most guides on this topic never mention.
For the wider account options, start with the full non-resident business banking comparison.
Deal with both before you open anything, because one of them can change what you form.
The permit mechanism, and why the answer is not simply "no permit needed"
Poland's instrument is the Foreign Exchange Law of 27 July 2002. Under it, outward investment carries no restriction for EU, EEA and OECD destinations, and an individual foreign exchange permit is required for third countries.
The United States is an OECD member. So on the face of the framework, a US investment sits in the unrestricted category rather than the permit category. That is the answer most Polish founders need.
But read the architecture rather than just the outcome, because the architecture is unusual. Germany abolished exchange controls outright in 2013. France has had none since 1989 under Article L151-1. Spain operates a declaration regime with no permit at all. Poland kept a permit mechanism and carved out the blocs — which means the permissive result for the US depends on a bloc membership rather than on the absence of a control.
Check before you rely on this, and more here than in most of these guides. A detailed founder-level outward-investment rule is not publicly documented in the act text, and Polish foreign-exchange legislation has been the subject of ongoing amendment discussion. Confirm your own position with NBP guidance or a Polish adviser before you move a material sum. Do not treat "the US is OECD, so I am fine" as a finished answer just because a guide handed you the framework.
Beyond that, the operational picture is straightforward: standard AML only for outward wire documentation, no restriction on holding or receiving USD, and no specific remittance rule. Compare a Moroccan founder inside the IGOC's categories or an Egyptian one selecting a purpose-of-payment code on every transfer, and you will see you are at the easier end.
A US LLC does not put you outside Polish law. Your transfer out of your Polish account is a Polish transaction; your US company's payments to other US companies are domestic to the US. Both hold at once, and any structure marketed on the basis that the first stops being true is one to refuse.
The provision to read before you form anything
This is the most consequential item on the page and it belongs before the banking mechanics.
Poland has controlled-foreign-company rules with named statutory homes: CIT Act Article 24a for companies and PIT Act Article 30f for individuals.
If you are a Polish tax resident holding a US LLC, that regime exists and applies on its own terms. Whether it reaches your structure depends on facts a guide cannot assess — so get Article 24a or Article 30f applied to your situation by a Polish adviser before you form, not after the account is open.
No rate or threshold appears here. A 19% figure circulates and is not asserted, because those are details to read out of the current provisions rather than out of an article.
Polish tax residence itself turns on your centre of personal or economic interests in Poland, or 183 or more days in the country, within a worldwide-income framework. Corporate residence turns on the registered office or place of management — which is the phrase to sit with if you will be running a US entity from Kraków, because a place-of-management test does not care which state issued your formation certificate.
The IRS publishes US–Poland income-tax treaty documents for the 1974 convention. That is an old convention still in the IRS repository, and how it applies to your income type is a question for the text and a cross-border adviser. A treaty affects tax. It does nothing for your credit file, and no provider has ever onboarded anyone because one exists.
What a US provider will ask for, and what Poland gives you
No universal financial-provider onboarding checklist for Poland is publicly documented, so I am not going to publish one and imply every provider accepts it — confirm requirements with each provider directly. Poland has a CRBR beneficial-ownership and AML framework, and each provider's requirements remain its own and risk-based.
What you can produce is well-structured. Polish business identifiers are NIP, REGON, and KRS or CEIDG depending on your entity form. Those are the references a US provider is most likely to want when it asks you to substantiate a real operating business, and Poland's identifier system is more granular than most — a tax number, a statistical number, and a register entry, each doing a different job.
Have ready: your US formation documents, the EIN letter, your NIP and REGON, your KRS or CEIDG entry, your CRBR position if relevant, proof of your Polish address in the forms you hold, and your passport. Then expect a request you did not anticipate, because that is what risk-based onboarding means.
The address question is usually the real obstacle, and it is the US address rather than the Polish one — specifically, what you are willing to say about how the entity uses it.
Where you stand on providers
Every major provider accepts Poland: Stripe, Wise, PayPal, Payoneer, Airwallex and Shopify Payments are all available. Mercury does not exclude Poland, though approval is Mercury's decision on your application. Relay requires the US entity formed first, which is sequencing rather than rejection.
So the constraint on you is documentation, not eligibility. A Moroccan or Egyptian founder faces four unavailable providers; a Turkish founder finds Mercury prohibited outright and Stripe, Wise, Airwallex and Shopify Payments closed. Do not solve a problem you do not have, and be sceptical of comparison content written for founders who do.
Check before you rely on this: provider country policies change without announcement. Verify each one directly before you build a stack on it.
The domestic-sophistication trap
Poland has genuinely strong domestic payment infrastructure. KIR operates Elixir and Express Elixir, and BLIK is a domestic system used at scale.
None of that makes a US provider's onboarding or an international transfer any simpler. Domestic sophistication and cross-border ease are unrelated, and Polish founders — accustomed to domestic transfers that settle in seconds and to BLIK's ubiquity — routinely expect the cross-border experience to match. It does not, and expecting it to produces frustration with a process that is working normally.
What Poland holds about your credit
BIK is the consumer credit information institution. BIG InfoMonitor and KRD sit alongside it on the commercial and debtor-register side, though their complete scope is not clearly documented in public regulator material. KNF is the financial regulator.
That is a three-layer structure, and knowing which layer holds what is useful before you describe your Polish record to a US institution.
Two boundaries. A statutory report-access frequency is not documented — a six-month free-access figure circulates in Polish consumer advice and is not stated here as a rule, so check BIK's current published terms rather than a forum. And no route by which Polish credit history is recognised abroad is publicly documented; ask BIK for their current position if you need it, and treat any service claiming to move your BIK record into a US bureau as making a claim it cannot support.
Practically: you arrive in the United States as a new file. Your Polish record is diagnostic for you rather than persuasive to them.
What Polish founders get wrong
Concluding they need an individual FX permit for a US investment. The permit applies to third countries and the US is an OECD member, so the carve-out is the relevant provision. Founders who read half the Foreign Exchange Law sometimes abandon the plan entirely.
Or the reverse — treating the OECD carve-out as a finished answer. A detailed founder-level rule is not publicly documented in the act text and the legislation has been under amendment discussion. Verify your own case.
Believing Poland has no CFC regime because nobody mentioned it. CIT Article 24a and PIT Article 30f exist. This is the most expensive mistake available to a Polish founder with a US entity, and it compounds annually.
Forming a US LLC and assuming the residence question is settled. Corporate residence turns on registered office or place of management. Running it from Poland engages a test that incorporation does not answer.
Quoting a six-month free BIK access entitlement as law. It is not documented in the statutory text. Check BIK's current terms.
Treating BLIK ubiquity as evidence of easy cross-border payment. Elixir, Express Elixir and BLIK are domestic. Your US onboarding is unaffected by any of them.
The practical sequence
Before you form. Get CIT Article 24a or PIT Article 30f applied to your facts by a Polish adviser, and get the corporate-residence question answered if you will manage the entity from Poland. Confirm your own outward-investment position with NBP guidance rather than relying on the bloc carve-out alone.
Forming and opening. Form the entity, get the EIN, then apply to providers, because Relay will not onboard before the company exists. Get the ITIN if your situation requires one; Form W-7 direct to the IRS. Decide what you will say about the US address before a form asks you.
Moving the funds. Standard AML applies and no purpose code is required, but your bank runs its own process. Keep records of what you transferred and why — that file is what answers a source-of-funds question later.
After opening. Pull your BIK report and read it. When you later pull US reports, check how your name has been recorded: Polish diacritics — ł, ą, ś, ż — are handled inconsistently by US systems, and a transliterated surname on one account with an accented one on another is how a file splits in two.
When you don't need us
Pull your own BIK report and check BIK's current access terms yourself. Nobody should charge you to request your own file.
The ITIN is Form W-7 to the IRS, and simple cases need no intermediary.
Every major provider accepts Polish founders. If you can satisfy onboarding directly, do it directly — none of them charge less because someone made an introduction.
The Article 24a and Article 30f question belongs with a Polish tax adviser. Pay for their time and get it in writing.
Where help earns its cost is the US formation and EIN, the address problem, and knowing which provider fits your profile before you spend applications finding out.
