The KNF (Komisja Nadzoru Finansowego, Polish Financial Supervision Authority) regulates Poland's financial markets. A broker can serve Polish clients by being KNF-authorised or by passporting an EU licence (such as CySEC) under MiFID II. XTB, one of the world's largest listed brokers, is headquartered in Warsaw and KNF-regulated. The KNF maintains public warnings about unauthorised entities, so verify any broker before depositing.
Leverage Limits
As an EU member, Poland applies the ESMA leverage caps of 1:30 on major forex pairs for retail clients, with lower limits on other instruments. Polish retail traders benefit from negative-balance protection. As always, using conservative leverage is the smart approach for managing risk.
Taxes on Trading Profits in Poland
In Poland, profits from trading are generally subject to a flat 19% capital gains tax (podatek od zysków kapitałowych, sometimes called the "Belka tax"). Polish brokers typically provide a PIT-8C form to help you declare your gains, which you report in your annual PIT return; foreign brokers may require you to calculate and declare gains yourself. Rules change and circumstances differ — consult a doradca podatkowy (tax adviser) about your situation.
