Are crypto wallets legal in Poland?
Holding crypto in a wallet you control, known as self custody, is legal in Poland. As of May 2026 there is no law that bans owning a software or hardware wallet, and you do not need a licence to hold your own crypto. A business that holds crypto for other people provides a custody service that falls under the European Union Markets in Crypto Assets Regulation, with the Komisja Nadzoru Finansowego, the KNF, as the intended supervisor. Tax does not arise from holding crypto in a wallet, only when you dispose of it, taxed at a flat 19 percent by the Krajowa Administracja Skarbowa, the KAS. This is information, not advice.
Are crypto wallets legal in Poland?
Yes. As of May 2026, owning and using a self custody wallet is legal in Poland. A crypto wallet stores the private keys that let you move your crypto. With a self custody wallet, whether a phone app, a browser extension, or a hardware device, you hold the keys yourself, and there is no Polish rule that requires a licence to hold your own crypto or that prohibits self custody. With a custodial wallet, a company holds the keys on your behalf, which is a different legal situation covered below.
When a wallet provider is regulated
The regulated activity is holding crypto for others, not holding your own. Under the European Union Markets in Crypto Assets Regulation, known as MiCA, which has applied directly across the Union since 30 December 2024, the custody and administration of crypto assets on behalf of clients is a crypto asset service. A firm that offers a custodial wallet or otherwise holds customer crypto is generally expected to hold authorisation as a crypto asset service provider. In Poland the intended supervisor is the Komisja Nadzoru Finansowego, the KNF, the Polish Financial Supervision Authority. As of May 2026 the national act formally empowering the KNF was delayed, and providers already entered in the Polish register of virtual currency activities may operate under a transition that ends on 1 July 2026. Holding your own keys in a self custody wallet does not make you a regulated provider. See the Poland regulation page for the framework.
How wallet holdings are treated for tax
As of May 2026, Poland taxes the disposal of crypto, not the act of holding it in a wallet. Moving crypto between your own wallets is not a taxable event, and Poland does not levy an annual wealth tax on the crypto sitting in your wallet. Tax of a flat 19 percent arises when you dispose of crypto for money, goods, or services, reported on the annual PIT-38 return, while a crypto to crypto swap is not a taxable event. The tax authority is the Krajowa Administracja Skarbowa, the KAS. Keep records of your acquisition costs and transactions, including transfers between wallets, so you can report accurately. See the Poland tax page and verify before filing.
Choosing and using a wallet
Most people in Poland buy crypto on a regulated exchange and then decide whether to leave it in the exchange custodial wallet or move it to a self custody wallet they control. With self custody you take on full responsibility for your keys and recovery phrase, and there is usually no provider that can restore access if you lose them. That responsibility is the core trade off: self custody removes reliance on a third party but places the entire risk of loss on you. We do not endorse any specific wallet product. To buy the crypto you intend to hold, use a platform that is genuinely available to residents of Poland.
Compare available exchanges in Poland

We list a platform here only where it is genuinely available to this country, and we do not endorse any wallet product.
