XTB vs DEGIRO vs Interactive Brokers — Which Broker Should Polish Investors Choose in 2026?

Choosing a broker is one of the most important decisions for any investor. The right broker saves you money on fees, gives you access to the markets you need, and provides a platform you actually enjoy using.

For Polish investors in 2026, three brokers dominate the conversation: XTB (the local champion), DEGIRO (the European low-cost disruptor), and Interactive Brokers (the global heavyweight). Each has distinct strengths and weaknesses.

This comparison covers everything that matters: commissions, available instruments, IKE/IKZE support, currency conversion, platforms, and the real cost of investing through each broker.

Broker Profiles

XTB

XTB (X-Trade Brokers) is a Polish-founded broker, publicly listed on the Warsaw Stock Exchange (GPW). Founded in 2002, it's one of the largest listed FX/CFD brokers in Europe. In recent years, XTB has pivoted toward commission-free stock and ETF investing, attracting a massive retail investor base in Poland.

• Headquarters: Warsaw, Poland
• Regulated by: KNF (Polish Financial Supervision Authority), plus FCA, CySEC, and others
• Clients: ~1.5 million+
• Key offering: Commission-free stocks/ETFs (up to EUR 100,000/month), CFDs, Forex

DEGIRO

DEGIRO is a Dutch online broker, now owned by flatexDEGIRO AG (listed on the Frankfurt Stock Exchange). Founded in 2013, it disrupted European brokerage with ultra-low fees and access to 50+ exchanges worldwide.

• Headquarters: Amsterdam, Netherlands
• Regulated by: AFM (Dutch Authority for Financial Markets), BaFin (German regulator)
• Clients: ~2.5 million+
• Key offering: Low-cost access to global markets, wide exchange coverage

Interactive Brokers (IBKR)

Interactive Brokers is the global standard for serious investors and traders. Founded in 1978 by Thomas Peterffy, it offers access to 150+ markets in 33 countries with some of the lowest margin rates in the industry.

• Headquarters: Greenwich, Connecticut, USA
• Regulated by: SEC, FINRA, FCA, MNB (Hungary for EU clients via IBCE), and others
• Clients: ~3 million+
• Key offering: Global market access, professional-grade platform, lowest margin rates

Commission & Fee Comparison

Stock & ETF Trading Fees

XTB is the clear winner on commissions for most retail investors. With EUR 100,000/month of free trading, the vast majority of Polish investors will never pay a stock/ETF commission at XTB.

DEGIRO is cheap but not free. Their "Core Selection" of popular ETFs (including many Vanguard and iShares funds) can be traded once per month for free.

Interactive Brokers uses a tiered or fixed pricing model. While not the cheapest for small orders, costs are very competitive for larger positions and become the cheapest option for high-volume traders.

Currency Conversion Fees

This is often the hidden cost that investors overlook. If you're a PLN-based investor buying US stocks, you need to convert PLN to USD.

Interactive Brokers wins decisively here. Converting PLN 50,000 to USD:

• XTB: ~250 PLN cost (0.5% spread)
• DEGIRO: ~125 PLN cost (0.25%)
• IBKR: ~8 PLN cost ($2 flat)

For investors regularly buying foreign assets, IBKR's FX costs can save hundreds or even thousands of PLN annually. This often negates XTB's commission-free advantage.

Account Fees

Available Markets & Instruments

Interactive Brokers offers the widest market access by far. If you want to invest in Japanese stocks, trade options on US indices, or buy government bonds, IBKR is the only option of the three that covers all these needs.

XTB is best for straightforward stock and ETF investing plus CFD trading. Its ETF selection has grown but is still smaller than DEGIRO or IBKR.

DEGIRO strikes a middle ground — more markets than XTB, fewer than IBKR, but with a simple interface.

IKE & IKZE Support

For Polish investors, tax-advantaged accounts (IKE and IKZE) are crucial for long-term wealth building.

XTB is the only broker of the three that offers IKE/IKZE accounts. This is a massive advantage for Polish investors. With IKE, you pay no capital gains tax on withdrawal after age 60. With IKZE, contributions are tax-deductible.

If IKE/IKZE is your priority, XTB is the default choice. For a regular taxable account alongside your IKE, you might use DEGIRO or IBKR.

Other Polish brokers offering IKE/IKZE include mBank (eMakler), Bossa (BM BOŚ), and DM PKO BP.

Trading Platforms

XTB — xStation 5

• Modern, clean web and mobile platform
• Built in-house, well-optimized
• Advanced charting with TradingView integration
• Sentiment indicators and market analysis
• Portfolio analytics and performance tracking
• Great for: Beginners and intermediate investors who want a polished, easy-to-use platform

DEGIRO — Web Trader

• Simple, no-frills web platform
• Limited charting capabilities
• Basic order types
• Mobile app is functional but basic
• Great for: Buy-and-hold investors who trade infrequently and want simplicity

Interactive Brokers — Trader Workstation (TWS) & Web/Mobile

• Trader Workstation (TWS): Professional desktop platform, powerful but complex
• Client Portal: Web-based, cleaner and simpler than TWS
• IBKR Mobile: Full-featured mobile app
• Advanced order types, algos, portfolio analytics
• IBKR GlobalTrader: Simplified app for casual investors
• Great for: Serious investors and active traders who need professional tools

Tax Reporting for Polish Investors

Filing taxes on foreign investment income (PIT-38) can be complicated. Here's how each broker helps:

• XTB: Provides a PIT-8C form (for Polish taxable accounts) — easiest for Polish tax filing. IKE/IKZE accounts don't require annual tax reporting.
• DEGIRO: Provides an annual report, but it's not in PIT-8C format. You'll need to manually calculate your tax or use a service like pit.pl.
• Interactive Brokers: Provides detailed activity statements. No PIT-8C. Manual calculation required or use third-party tools.

If you want minimal tax headaches, XTB's PIT-8C is a significant convenience advantage.

Real Cost of Investing — Example Scenarios

Scenario 1: Monthly EUR 500 into a global ETF (e.g., VWCE)

Annual cost over 12 monthly purchases of EUR 500:

Result: IBKR and DEGIRO are nearly tied and both significantly cheaper than XTB, primarily because of FX conversion costs.

Scenario 2: Quarterly PLN 10,000 into Polish stocks/ETFs on GPW

Annual cost over 4 purchases of 10,000 PLN:

Result: XTB is the clear winner for Polish market investing.

Scenario 3: Large one-time investment of USD 20,000 into US stocks

Result: IBKR saves nearly 400 PLN on a single large foreign investment thanks to its minimal FX costs.

Safety & Investor Protection

All three brokers are well-regulated and publicly listed, providing transparency and accountability. Your securities are held in segregated accounts separate from the broker's own assets.

Who Should Choose Which Broker?

Choose XTB if you:

• Are a Polish investor who wants the simplest experience
• Want IKE/IKZE accounts (XTB is the only option here)
• Primarily invest in Polish stocks and ETFs on GPW
• Are a beginner who values a clean, modern platform
• Want PIT-8C tax reporting without hassle
• Trade CFDs or Forex alongside your investments

Typical XTB user: A Polish salaried employee who invests monthly into a few ETFs via IKE, occasionally trades Polish stocks, and wants everything in one place with Polish-language support.

Choose DEGIRO if you:

• Want low-cost access to European and global exchanges
• Are a buy-and-hold investor who trades infrequently
• Want access to the Core Selection of free ETFs
• Don't need IKE/IKZE (using a Polish broker for that separately)
• Want a simple platform without bells and whistles
• Invest primarily in EUR-denominated assets (avoiding FX fees)

Typical DEGIRO user: An intermediate investor who buys VWCE monthly and wants access to more European exchanges than XTB offers, with lower FX costs.

Choose Interactive Brokers if you:

• Need global market access (Asia, options, futures, bonds)
• Make large investments where FX costs matter (saving hundreds/thousands on conversions)
• Are an active trader who needs professional tools
• Want the lowest all-in costs for international investing
• Don't mind a more complex platform
• Want to trade options or other derivatives

Typical IBKR user: An experienced investor with a six-figure portfolio who invests globally, values the lowest possible costs, and uses advanced order types.

Can You Use Multiple Brokers?

Many Polish investors use a two-broker strategy:

1. XTB for IKE/IKZE: Tax-advantaged investing in Polish and EU ETFs
2. IBKR for taxable account: Global investing with the lowest FX and commission costs

This combination gives you tax optimization through IKE/IKZE plus access to global markets at minimal cost.

Key Trends for 2026

• XTB continues expanding its investment product range and has introduced real cryptocurrency trading. Its IKE product is increasingly popular.
• DEGIRO has integrated more with flatex after the merger, with some growing pains around account migration and fee changes.
• Interactive Brokers keeps lowering its barriers to entry — no minimums, simplified apps — while maintaining its edge for serious investors.
• Competition: All three face pressure from new entrants like Trading 212 and eToro, which is driving fees lower across the board.

Summary Table

FAQ

Is XTB really free? What's the catch?

XTB offers commission-free stock and ETF trading up to EUR 100,000 in monthly turnover. After that, a 0.2% commission applies. The main way XTB makes money from investment accounts is through FX spreads (the ~0.5% conversion cost when you buy foreign assets) and from CFD trading, which is their core business. For the vast majority of retail investors, XTB is genuinely free to use.

Can I transfer my portfolio from one broker to another?

Yes, but it can be complex and costly. DEGIRO charges EUR 10 per position for outgoing transfers. XTB and IBKR have varying fees. The process typically takes 2-6 weeks. For small portfolios, it may be cheaper to sell, transfer cash, and rebuy — though this triggers tax events in taxable accounts.

Which broker is best for ETF investing from Poland?

It depends on your approach. For IKE/IKZE: XTB is the only choice. For a taxable account with regular small investments: DEGIRO's Core Selection ETFs are hard to beat. For large lump-sum investments in international ETFs: IBKR saves the most on FX costs. Many investors use XTB (IKE) + IBKR (taxable) as their optimal combination.

Do I need to file taxes separately for foreign brokers?

Yes. Polish tax residents must declare all worldwide investment income on PIT-38. XTB provides PIT-8C which makes this easy. For DEGIRO and IBKR, you'll need to calculate your gains/losses from their annual reports. Consider using tax software or an accountant if you have complex positions across multiple foreign brokers.

Is my money safe with these brokers?

All three are regulated, publicly listed companies with segregated client accounts. Your securities are held separately from the broker's assets. Investor compensation schemes provide additional protection: EUR 20,000-20,100 in the EU, up to $500,000 SIPC for IBKR US accounts. The real risk is not broker insolvency — it's market risk on your investments.

Expanded FAQ

Can I transfer my existing portfolio between brokers?

Transfer Process:

• XTB → DEGIRO/IBKR: Possible but complex, fees apply
• DEGIRO → others: €10 per position transfer fee
• IBKR → others: Various fees depending on destination

Practical Reality: For small portfolios (under €50,000), it's often cheaper to sell positions, transfer cash, and repurchase. This triggers tax consequences in taxable accounts but avoids transfer fees.

• Reduced to 15% with proper tax forms (W-8BEN)
• Further reduction possible with Polish tax treaty

• May be reduced with tax treaties
• Some countries have no withholding tax
• Dividends paid in local currency

Tax Recovery:

• Overpaid withholding tax can often be reclaimed

• DEGIRO: German investor protection up to €20,000
• IBKR: SIPC protection up to $500,000 (US accounts), €20,000 (EU accounts)

Base Currency Effect:

• Can work for or against you

Example: Buy $10,000 worth of US stocks when USD/PLN = 4.00

• Cost: 40,000 PLN
• If stocks don't move but USD/PLN rises to 4.20, your position is worth 42,000 PLN
• Currency gains can amplify or reduce investment returns
