US exchanges are open to Polish investors. What changes with your residence is which brokers will accept you, how much US tax is withheld from your dividends, and what your funding costs.
The three things that matter from Poland: (1) pick a broker that accepts Polish residents —7 of the brokers we cover give real share ownership and 3 offer CFD exposure only; (2) file a W-8BEN — 15% treaty withholding on US dividends where claimed.; (3) control your currency conversion cost, which for a small account usually exceeds the commission.
15% treaty withholding on US dividends where claimed.
The W-8BEN form is what claims your treaty rate. Without it, the default US withholding on dividends is 30%.
Withholding applies to dividends, not to capital gains, for non-resident individuals.
Your home tax obligation is separate and usually still applies, with a credit for tax already withheld in the US.
US estate tax can apply to US-situs assets held by non-residents above a low threshold — worth checking at larger balances.
General information, not tax advice. Rules change and personal circumstances differ — confirm with a qualified adviser in Poland.
Brokers that accept Polish residents
Eligibility is set by each broker's onboarding rules and can change without notice — always confirm on the broker's own application form before funding.
A CFD and spread-betting broker, not a US stockbroker. It is on this site because for most non-US traders it is one of the few regulated routes to US-share exposure with leverage.

CFDs are leveraged: you do not own the share, get no shareholder rights, and can lose more than you expect
Low entry barrier and a wide share-CFD list; the trade-off is that everything is a derivative, so there is no dividend ownership or voting right — only cash adjustments.

CFDs are leveraged and you do not own the underlying share
Yes. US exchanges are open to foreign investors through any broker that accepts Poland residency. Most US-domiciled retail brokerages do not open accounts for non-residents, so the practical routes are international brokers and regulated CFD providers.
What tax do I pay on US dividends from Poland?
15% treaty withholding on US dividends where claimed. You claim any treaty rate by filing a W-8BEN with your broker; it expires and must be renewed. This is general information, not tax advice — confirm your position with a Polish tax professional.
Do I need to pay US capital gains tax?
Generally no. The US does not tax capital gains of non-resident individuals on US securities. Your gains are usually taxable in your country of residence instead.
Is KNF involved?
KNF regulates financial services inside Poland, but a foreign broker serving you cross-border is normally authorised in its own jurisdiction rather than locally. That matters because your compensation scheme and leverage limits follow the entity that holds your account, not your address.
What is the cheapest way to fund a US stock account from Poland?
Usually a multi-currency transfer into a USD sub-account rather than letting the broker convert at its own rate. For small balances, the FX conversion charge is typically a larger cost than commission.
