How to Choose a Brokerage Account — Complete Guide 2026

Quick Answer

To choose a brokerage account, compare total cost of ownership, not just headline commission — cost differences can reach PLN 500-2000 a year for active investors. Check transaction commissions (Polish stocks from PLN 3, ETFs often 0%), account, inactivity and withdrawal fees, and hidden costs like currency conversion spreads (0.2-2%). Confirm the markets you need (GPW, NYSE/NASDAQ, XETRA, LSE) and verify regulation: KNF-licensed brokers segregate client assets and protect cash up to EUR 22,000 via the KDPW guarantee. Match the broker to your profile — passive ETF saver, active investor, or beginner. This is educational information, not investment advice.

What to pay attention to when choosing a brokerage account?

How to choose a brokerage account — step by step

Step 1: Define your investor profile

Beginner passive (ETFs):

• Priority: low ETF costs
• Recommendation: XTB, Trading 212, mBank

Beginner active (Polish stocks):

• Priority: education + low commissions
• Recommendation: mBank, BM mBanku, XTB

Step 2: Calculate annual costs

Example for ETF investor (PLN 24,000 annually):

Step 3: Test the platform

Checklist:

• Register demo account
• Test order placement
• Check mobile application
• Contact customer service

Step 4: Check hidden costs

Often overlooked fees:

• Currency conversion (spread 0.2-2%)
• Dividend payments (PLN 0-25 per transaction)
• Tax reports (PLN 0-200 annually)
• Market data (PLN 0-100 monthly)

Most common mistakes when choosing a broker

1. Focusing only on commission

Low commissions aren't everything. A poor platform can cost more than savings on fees.

2. Ignoring security

Don't open an account with the "cheapest" unlicensed broker. The risk of losing all savings is real.

3. Not testing the platform

Many people open accounts without testing the platform. Then regret it during the first system failure.

4. Not reading terms and conditions

Hidden fees are in the fine print. Always read the fee and commission table.

When to change brokers?

Signs it's time to change:

• High costs compared to competition
• Frequent failures of the platform
• Poor customer service
• Lack of development — broker doesn't add new features

How to transfer portfolio:

1. Open account with new broker
2. Securities transfer order (usually free)
3. Close old account after transfer

FAQ

Which Polish brokerage accounts are supervised by KNF?

The most popular KNF-supervised brokers in Poland include XTB, DM PKO BP, BOSSA (DM BOŚ), DM mBanku (eMakler), Santander Biuro Maklerskie, and Millennium DM. Foreign brokers operating in Poland under MiFID II passporting (e.g., Interactive Brokers, DEGIRO) are supervised by their home regulators. KNF supervision provides Polish-language complaints procedures and stronger local enforcement.

What is the difference between XTB, DM PKO BP and BOSSA?

XTB offers commission-free ETFs up to EUR 100k monthly turnover and a modern mobile app, but charges higher fees on Polish equities. DM PKO BP is integrated with PKO banking, offers IKE/IKZE accounts, and has wide instrument coverage but higher commissions. BOSSA (DM BOŚ) is known for low commissions on Polish stocks and advanced tools, but the platform is less beginner-friendly.

Do I need a brokerage account for IKE or IKZE?

Yes, IKE and IKZE in the form of an investment account (IKE-inwestycyjne) require a brokerage account at a licensed broker. DM PKO BP, BOSSA, DM mBanku, and several other Polish brokers offer these tax-advantaged retirement wrappers. Make sure to compare fees and available instruments within the IKE/IKZE wrapper, as offerings vary by broker.

What fees should I check before opening a brokerage account?

Look at transaction commission (per trade, with minimum), account maintenance fee, inactivity fee, currency conversion spread on FX trades, withdrawal fees, and the cost of receiving tax reports (PIT-8C). For ETF investors, the per-trade minimum can dominate total cost on small recurring purchases. Total cost of ownership matters more than headline commission rates.

Are my funds safe if my broker goes bankrupt?

In Poland, KNF-licensed brokers must segregate client assets from their own balance sheet, so securities are typically returned to clients in case of broker bankruptcy. The Polish System Rekompensat (KDPW guarantee) protects cash up to EUR 22,000 per investor. This is regulatory information, not investment advice — always read the broker's risk disclosure before opening an account.
