Best Investment Apps in Poland 2026 — 8 Platforms Compared

Choosing the right investment app can save you thousands of zloty in fees over a decade. With over 2.1 million brokerage accounts now active in Poland (up 18% from 2024), competition between platforms has driven commissions down and feature sets up. But not all brokers are created equal — the best choice depends on what you invest in, how much you invest, and whether you want tax-advantaged accounts like IKE.

Quick Answer: For most Polish investors buying ETFs, XTB offers the strongest overall package in 2026 — zero-commission ETF trading up to 100,000 EUR/month, IKE account support, fractional shares, and a polished mobile app. If you need access to US-listed ETFs or the lowest possible margin rates, Interactive Brokers is the power-user choice. For casual investors starting with small amounts, Revolut and Trading 212 provide the simplest onboarding experience.

How We Compared These 8 Platforms

We evaluated each platform across six categories that matter most to Polish investors:

1. Commissions and fees — Trading costs, FX conversion, inactivity fees
2. ETF access — Number of available ETFs, which exchanges are supported
3. Fractional shares — Ability to buy partial shares for small portfolios
4. IKE availability — Tax-advantaged individual retirement account support
5. Mobile app quality — User experience, reliability, feature completeness
6. Minimum deposit — Barrier to entry for new investors

We also considered regulatory oversight, currency conversion costs, and the availability of Polish-language support.

The Real Cost of Fees: A 10-Year Comparison

Fees compound just like returns. Here is what a Polish investor would pay over 10 years, assuming 500 PLN/month invested in a European ETF, 8% annual return, and quarterly rebalancing:

The difference between the cheapest option (Trading 212) and the most expensive (Bossa) is approximately 1,690 PLN over 10 years on a modest 500 PLN/month investment. For larger portfolios, the gap widens substantially.

IKE: The Tax Advantage Worth Thousands

If you plan to invest for retirement, historical data suggests that using an IKE account can save you significant money on taxes. In 2026, the IKE contribution limit is 26,019.60 PLN per year. Capital gains within an IKE account are tax-free upon withdrawal after age 60 (or 55 with at least 5 years of contributions).

Example calculation:

• 20 years of investing 2,000 PLN/month at 8% annual return
• Final portfolio value: ~1,178,000 PLN
• Capital gains: ~698,000 PLN
• Tax without IKE (19% Belka tax): ~132,620 PLN
• Tax with IKE: 0 PLN

Only three brokers on this list offer IKE: XTB, mBank eMakler, and Bossa. If long-term retirement investing is your primary goal, this feature alone may outweigh any commission differences.

Security and Regulation

All eight platforms are regulated by at least one EU financial authority. However, only four are directly supervised by KNF (Komisja Nadzoru Finansowego):

KNF regulation means you deal with a Polish legal entity, complaints go through Polish ombudsman procedures, and your assets are held at KDPW (Polish Central Securities Depository).

FAQ

Which investment app has the lowest fees in Poland?

For ETF investing, Trading 212 and XTB offer zero-commission trades. However, the total cost includes FX conversion: Trading 212 charges 0.15% while XTB charges 0.50%. For sheer cost efficiency on foreign-currency ETFs, Trading 212 or Interactive Brokers (0.002% FX) tend to be the cheapest options at scale.

Can I open an IKE account through an investment app?

Yes, but only through select brokers. In 2026, XTB, mBank eMakler, and Bossa offer IKE accounts. International platforms like Revolut, eToro, DEGIRO, IBKR, and Trading 212 do not support IKE. You can have only one active IKE account at a time across all institutions.

Is XTB safe for investing?

XTB is regulated by the Polish Financial Supervision Authority (KNF), listed on the Warsaw Stock Exchange, and holds client assets separately from company funds at KDPW. Investor compensation covers up to 20,100 EUR per client. Historical data suggests it is among the more transparent brokers in Poland due to its public-company reporting requirements.

Which app is best for investing small amounts like 100-500 PLN per month?

For small, regular investments, platforms with fractional shares and zero commissions work best. XTB (minimum 10 PLN per fractional trade), Trading 212 (minimum 1 EUR), and Revolut (minimum 1 PLN) all support small-amount investing. Trading 212's AutoInvest feature is particularly useful for automated monthly investing with custom allocations.

Do I need to file taxes on investment gains from foreign brokers?

Yes. Polish tax residents must report all capital gains on their annual PIT-38 declaration, regardless of which broker they use. Some brokers (XTB, mBank eMakler, Bossa) provide PIT-8C forms that simplify Polish tax filing. Foreign brokers typically provide annual statements that you must manually translate into PIT-38 entries. Some investors consider using tax software or an accountant for foreign broker statements.

What happens to my investments if a broker goes bankrupt?

Your stocks and ETFs are held separately from the broker's assets — they are registered in your name at a central depository (KDPW in Poland, Euroclear in Europe). If a broker fails, your assets are transferred to another broker. Cash balances are protected up to 20,000 EUR (EU) or 20,100 EUR (Poland/KDPW). This is similar to how bank deposits are protected by BFG up to 100,000 EUR.

Can I transfer my portfolio between brokers?

Yes, most brokers support incoming and outgoing portfolio transfers (ACATS or manual transfer). However, the process can take 2-6 weeks and some brokers charge transfer-out fees (DEGIRO charges 10 EUR per position, eToro does not support outgoing transfers at all). XTB, IBKR, and Trading 212 accept incoming transfers at no cost.
