Short reviews of the best brokers

An exceptional trading platform in Belgium is Interactive Brokers. Founded in 1978 and publicly listed on NASDAQ (ticker: IBKR), Interactive Brokers is a global online broker that surpassed major financial crises, showing resilience and a rigorous risk management process.

Interactive Brokers offers an advanced investment platform that includes a wide range of products (stocks, options, mutual funds, ETFs, futures, bonds, and currencies) from over 170 markets, solid trade execution (IB SmartRouting), and a set of technical and fundamental tools to help you in your investment decisions.

For US stocks, commissions start at $0.0035 per share ($0.35 minimum per order), while for European stocks and ETFs, such as those on Euronext Brussels, costs are 0.05% of the order value (€1.25 minimum, €29 maximum on the Tiered plan, or a €3 minimum on the Fixed plan).

Beginners and intermediate investors have educational tools to explore, but the learning curve will be steep. Besides, customer service gives clear answers to your doubts, so there is no need to go back and forth.

On the downside, Interactive Brokers’ fee structure is quite complex, the registration process is lengthy (but fully online), and the broker doesn’t offer commission-free trading. However, when considering FX fees, narrower spreads, and the stock loan program, Interactive Brokers’ clients still get significant savings compared to most brokers.

Interactive Brokers also offers fractional shares, automatic currency conversion and a demo account, which make the platform more approachable for investors starting out. It pays interest on EUR cash above the first €10,000 (at the full rate for accounts above $100,000). Note that IBKR does not collect the stock exchange tax or withhold the capital gains tax for Belgian clients, so you declare both yourself.

Launched in 1992, Saxo is one of the most solid financial entities in the brokerage industry, with a proven track record. It lets you trade over 70,000 financial instruments through its two proprietary platforms: SaxoInvestor, aimed at investors who want a simpler interface, and SaxoTrader, available on web, desktop and mobile for more active users.

The wide range of cash and margin trading products across global markets includes stocks, ETFs, bonds, mutual funds, crypto ETPs, options, futures, CFDs and forex.

Ownership changed recently. In March 2026, the Swiss private banking group J. Safra Sarasin completed the acquisition of around 71% of Saxo from its previous majority shareholder, with founder Kim Fournais retaining roughly 28%. In July 2026, J. Safra Sarasin agreed to acquire that remaining stake as well, subject to regulatory approval.

For Saxo Belgium, the account tiers are Bronze, Silver (from €200,000) and Gold (from €1,000,000), with no minimum deposit required to open an account.

The pricing structure varies according to your account tier: the more you trade, the less you pay. On the Bronze tier, a US stock order costs 0.08% of the trade value (minimum $1) and a Euronext Brussels order 0.08% (minimum €2), falling to 0.05% on Silver and 0.03% on Gold. Currency conversion in Belgium costs 0.25% regardless of tier.

Following Saxo’s pricing overhaul, custody fees have been removed in Belgium and other core European markets, and there are no inactivity fees on investment accounts. One cost worth checking before you commit: transferring securities out to another broker costs €75 per line, so a portfolio with many positions is expensive to move.

The listed prices are approximate and will differ based on the resident country. For precise pricing details, refer to the platform’s trade tickets for a comprehensive overview.

Saxo Bank A/S is a fully licensed European bank under the supervision of the Danish Financial Supervisory Authority (FSA). It is a member of the Danish Guarantee Fund, which protects client cash deposits up to €100,000 and financial securities (stocks, ETFs,…) up to €20,000 per client.

As a Belgian branch, Saxo collects the stock exchange tax, withholds the Belgian tax on dividends and interest, and withholds the new capital gains tax when you sell, which is convenient but has a catch we explain in the tax section below.

Founded in 2013, DEGIRO is a low-cost brokerage firm that has become very popular due to its low rates. With more than 3 million investors, the platform is widely known for its “do-it-yourself” philosophy in the sense that you have everything at your disposal to start investing on your own. It offers a wide range of financial assets to trade, including stocks, ETFs, bonds, options, futures contracts, warrants, investment funds, and some leveraged products (not quite the same as CFDs, more info here). Crypto trading, launched in several EU countries in 2025, was not rolled out to Belgium.

The ETF Core Selection was restructured in October 2025. It now covers the full range of ETFs, ETCs and ETNs listed on Tradegate, over 1,000 products, for a €1 handling fee with no connectivity fee, and the previous Fair Use Policy no longer applies. Outside that selection, ETFs cost €3 per trade (€2 commission plus a €1 handling fee), as do Euronext stocks, while US stocks cost €2. A connectivity fee of up to €2.50 a year applies for each foreign exchange you use.

The web trading platform is basic, but it is efficient and straightforward to use. In a matter of minutes, you get used to it. The same applies to its mobile app. On the downside, there is an absence of significant fundamental research, no interest is paid on uninvested cash, and pricing alerts are missing. On taxes, DEGIRO collects the stock exchange tax for Belgian clients (you can choose to declare it yourself), but it does not withhold the capital gains tax, as it is not considered a Belgian broker.

Regarding security, DEGIRO operates through the Dutch branch of flatexDEGIRO Bank SE, a German-regulated bank supervised primarily by BaFin. In the unlikely event that the segregated assets cannot be returned to clients, DEGIRO falls under the German Investor Compensation Scheme, which compensates any losses from non-returned assets up to 90% (with a maximum of €20,000), so do bear this in mind if you are planning to invest much larger volumes. Furthermore, any money deposited on a DEGIRO Cash Account with flatexDEGIRO Bank SE will be guaranteed up to €100,000 under the German Deposit Guarantee Scheme.

Lightyear is a European investment app that operates via the entity Lightyear Europe AS, authorised and regulated by the Estonian Financial Supervision Authority (EFSA, licence number 4.1-1/31), with clients’ assets covered up to €20,000.

There are no Lightyear execution fees to trade ETFs (other fees may apply). Euro-denominated stocks, such as those listed on Euronext Brussels, cost €1 per order, US stocks cost 0.1% (maximum $1), and currency conversion costs 0.35% (this can be minimised with the multi-currency account in EUR, GBP and USD). Lightyear also offers competitive rates on cash through money market funds (MMFs): EUR 2.43%, GBP 3.92% and USD 3.91% (net of fees, as of October 2026). Savings are opt-in: you earn these rates only on money you move into a money market fund.

The investment platform is suitable for beginners and intermediate investors who can invest in fractional shares. With an easy-to-use app and around 6,000 stocks, ETFs and money market funds from the US, UK and Europe, Lightyear is a straightforward way to get exposure to the stock market.

Lightyear also offers a free share worth up to €100 with the promo code INVESTINGINTHEWEB.

There are, however, some downsides to Lightyear’s investing app: the product offering is limited (there are no options, commodities, or Forex), and there is no demo account. Lightyear also does not collect the Belgian stock exchange tax or withhold the capital gains tax, so you declare both yourself.

BUX has been a wholly owned subsidiary of ABN AMRO since 2024, though it continues to operate as a separate app under its own brand, and Belgium remains one of its markets.

It allows users to trade US and EU stocks (Dutch, German, Belgian, French, and Austrian) and ETFs. You also have access to fractional investing, making it easy to invest in companies with big share prices (Amazon, Tesla, Alphabet,…) starting for as little as €10.

Direct crypto trading is no longer available. BUX discontinued it in March 2024 and migrated remaining portfolios to a third party, but you can now get exposure to Bitcoin and Ethereum through crypto exchange-traded products (ETPs), bought on the exchange like an ETF.

Pricing depends on your plan. BUX Basic is free, BUX Plus costs €2.99 a month and BUX Prime €7.99 a month. A market or limit order in EU stocks and ETFs costs €3.99 on Basic, €1.99 on Plus and €0.99 on Prime, while US stocks cost €0.99 on every plan. Plus and Prime also include Zero Orders, executed at the end of the trading day with no commission. The currency conversion fee is 0.75% on Basic, 0.25% on Plus and 0.20% on Prime, and a variable service fee on invested assets also applies (see BUX fees). BUX collects the Belgian stock exchange tax for you, but it does not withhold the capital gains tax.

On the downside, the only place to trade is its mobile app (no desktop or web trading platform available), the products available are limited, and it has no demo account.

BUX is regulated by the Dutch Authority for Financial Markets (Autoriteit Financiële Markten, AFM). If you want to learn more, check out our BUX Review.

Founded in 2019, Revolut Trading is part of the Revolut app (existing since 2015) and provides its users with an efficient way to invest, all in one place. For clients in Belgium, investment services are provided by Revolut Securities Europe UAB, an investment firm authorised and regulated by the Bank of Lithuania.

The offering has broadened considerably. Alongside US-listed shares, Revolut now provides European-listed stocks, ETFs and bonds, plus crypto and commodities, with more than 4,500 tradable assets in total. Each plan includes a monthly allowance of commission-free trades, 1 on Standard, 3 on Plus, 5 on Premium and 10 on Metal and Ultra. Beyond that allowance, trades cost 0.25% with a €1 minimum (0.12% on Ultra). Crypto and gold carry their own separate charges.

The annual custody fee of 0.12% that Revolut used to charge was removed in February 2024, and there are no inactivity or withdrawal fees. Revolut does not collect the Belgian stock exchange tax or withhold the capital gains tax, so you declare both yourself.

The app is intuitive, and the account opening process is fully digital and fast. On the downside, the product range is still narrower than a full-service broker, with no CFDs, forex or options, and there is limited educational or research material. It is also worth checking the investor protection that applies: EEA clients under Revolut Securities Europe UAB have different cover from those who were previously served by other Revolut entities.
