BUX delivers accessible mobile investing across European shares and fractional US equities backed by ABN AMRO, but charges an annual 0.20% asset fee and bars outgoing portfolio transfers.
Founded in Amsterdam in 2014, BUX grew as a mobile-first discount brokerage initially known as BUX Zero. In 2024, Dutch banking group ABN AMRO completed its acquisition of BUX, integrating cash custody into ABN AMRO Clearing Bank N.V. The firm operates under the supervision of the Dutch Authority for the Financial Markets (AFM) and holds client securities via the bankruptcy-remote Stichting BUX Custody.

Best for European beginners and recurring ETF DCA investors seeking automated monthly index accumulation in euros.
Active traders wanting advanced technical charts, international investors outside its 8 European markets, or investors who plan to transfer shares out.
Regulated by the Dutch AFM with ABN AMRO ownership, but penalized €1.6M in 2024 over marketing inducement breaches.
When you deposit money with BUX, your funds enter an infrastructure regulated by the Dutch Authority for the Financial Markets (AFM) and De Nederlandsche Bank (DNB). BUX B.V. operates as an authorized European investment firm under MiFID II rules, giving you statutory segregation protections and recourse through Dutch financial dispute bodies. You can verify this status directly on the AFM public register using entity registration 58403949 before placing your first trade.
Shares are held through a separate Dutch foundation structure, but you cannot transfer your investments out to another broker.
When you purchase whole or fractional shares on BUX, the legal title is not registered directly on a personal central depository account in your name. Instead, BUX uses a bankruptcy-remote foundation structure known in Dutch law as a stichting. Under Article 4 of the Client Agreement, your financial instruments sit with Stichting BUX Custody, an independent legal entity formed exclusively to hold client assets isolated from BUX B.V. operating liabilities.
Cash protection follows a dual-track model. Your uninvested euro balances are deposited into a dedicated omnibus account maintained by ABN AMRO Clearing Bank N.V. Because the clearing partner holds a full European banking license, your money does not enter BUX corporate accounts, qualifying for Dutch deposit protection up to €100,000. Monthly PDF account overviews and real-time app ledgers report your position balances.
Standard trades cost €0.99 for US shares, but a 0.20% annual asset fee and 0.75% FX markup add ongoing friction.
If you invest €300 each month into your portfolio on the default BUX Basic plan, the headline trading costs look low, but ongoing friction quietly accumulates. BUX structures pricing across three tiers: Basic (€0 per month), Plus (€2.99 per month), and Prime (€7.99 per month). On the free Basic tier, regular US equity market orders cost €0.99 (about $1.13), European shares cost €3.99 (about $4.57), while automated monthly Investment Plan orders execute commission-free.
Offers core US and European equities with fractional shares, but lacks bonds, Asian bourses, and multi-currency cash handling.
With BUX, your market reach covers major Western exchanges, allowing you to build an equity portfolio across standard European and US names. You can access primary listings on the New York Stock Exchange, Nasdaq, Euronext Amsterdam, Euronext Paris, Euronext Brussels, and Germany's Xetra. This catalog spans over 2,500 individual stocks alongside Exchange-Traded Commodities (ETCs).
Passive ETF investors receive an accessible roster of European UCITS ETFs from providers such as iShares, State Street (SPDR), and VanEck. Because BUX supports fractional shares from a low €10 minimum threshold, you can purchase small slices of high-priced companies and popular index funds without accumulating odd lots of cash. Automated investment plans let you bundle these securities into recurring monthly baskets.
A polished mobile app designed for straightforward automated investing, with bare-bones technical charting and no API.
Operating BUX revolves entirely around its smartphone application on iOS and Android. Setting up automated investments, executing market orders, and browsing thematic collections takes just a few taps. If you are a mobile-first saver looking to build positions without confronting crowded desktop terminal windows, the user interface remains approachable and clean.
Operates free of payment for order flow with useful end-of-day Zero Orders, but lacks trailing stops and extended hours.
Order execution on BUX reflects its orientation toward long-term retail investors rather than fast-paced day traders. On the free BUX Basic plan you can place standard immediate Market Orders and automated Investment Plan orders. The paid BUX Plus and BUX Prime plans add predetermined Limit Orders, Good 'Til Canceled (GTC) orders, and end-of-day "Zero Orders". The Zero Order mechanism executes between 16:00 CET and market close, waiving transaction commissions on paid subscription plans and within automated Investment Plans, but it is not available for US stocks.
A notable integrity advantage is the absence of payment for order flow (PFOF). Because BUX operates out of the Netherlands, where regulatory authorities strictly prohibit broker kickbacks from market makers, client trades are not directed to execution venues paying rebates. BUX executes European orders through regulated trading venues and market makers under clear best-execution obligations.
Automated W-8BEN filing eases US dividend taxes, but BUX lacks tax wrappers and automated dividend reinvestment.
Account structures on BUX are simple, reflecting its retail consumer orientation. You can open an individual personal trading account, but corporate accounts, joint accounts, and custodial trust accounts for minors are not supported. Onboarding integrates with your tax identification number (such as the BSN in the Netherlands), and Dutch residents banking with ABN AMRO can link their profile directly.
Handling of US dividend tax works smoothly through digital W-8BEN processing. When you sign up, BUX automatically arranges electronic tax treaty validation, reducing US withholding tax on American dividends from the standard 30% default down to the 15% treaty rate for qualified residents. Dividends from European and US companies land directly into your cash balance once distributed.
Free euro deposits and withdrawals through SEPA and Tikkie, but foreign exchange is locked into automatic conversions.
Moving money in and out of BUX is straightforward and completely free of broker surcharges. BUX does not charge any deposit fees or withdrawal fees on cash transfers. In the Netherlands, Dutch clients can fund accounts instantly using Tikkie, while residents across all 8 supported European markets can transfer funds via SEPA bank transfers, which typically settle within 15 minutes if your bank supports SEPA Instant.
Account funding requires your bank account to match your registered BUX identity exactly. Third-party deposits or transfers originating from anonymous payment cards are rejected under European anti-money laundering controls. Withdrawals are processed back to your verified contra-account, taking between 1 and 2 business days to clear through conventional banking rails.
The core funding limitation is its single-currency design. BUX accounts operate exclusively in euros (EUR). You cannot hold, fund, or withdraw foreign currencies such as US dollars (USD) or British pounds (GBP). When purchasing US stocks, BUX automatically executes currency exchange at your tier's fixed markup (0.75% on Basic), leaving no option to maintain multi-currency cash buffers.
Practical educational articles for beginning investors, but institutional research and company valuation models are absent.
Research on BUX is curated primarily for novices taking their initial steps in personal wealth building. Through its website knowledge base and in-app stories, BUX provides a clean library of beginner-focused guides covering dollar-cost averaging, compound interest, ETF diversification, and portfolio rebalancing. The tone remains straightforward and jargon-free, serving as an accessible primer for retail savers.
Market news coverage includes daily updates and periodic digests highlighting macroeconomic trends and major company earnings reports. The application also conducts mandatory appropriateness questionnaires before permitting users to trade higher-risk instruments like Exchange-Traded Commodities (ETCs), satisfying European investor protection rules and avoiding high-pressure gamification mechanics.
Fast in-app chat and wide multilingual coverage across Europe, though phone support is not offered.
Reaching customer assistance at BUX takes place primarily through digital channels. You can submit queries directly via the in-app chat function or email the support desk at support@getbux.com. Support is available Monday through Friday, any time of day. A detailed self-service help portal answers common questions concerning deposit settlements, account verification, and investment plan maintenance.
Response efficiency reported by user communities on Trustpilot and regional investor forums indicates that standard verification and funding queries receive resolutions within 1 to 2 business days. Multilingual service represents a strong capability: representatives handle inquiries across six languages, including English, Dutch, French, German, Spanish, and Italian, matching its active European jurisdictions.
BUX accepts tax residents residing within 8 European Economic Area nations: the Netherlands, Belgium, France, Germany, Spain, Italy, Austria, and Ireland. Applicants must possess a valid national identification document or passport and maintain a linked bank account denominated in euros. US citizens and residents of non-supported European or overseas jurisdictions are not accepted.
BUX serves as a clean, practical on-ramp for European retail savers focused on building automated monthly ETF positions. Backing from ABN AMRO and statutory Dutch deposit insurance provide peace of mind regarding cash security. However, long-term buy-and-hold wealth accumulators must reckon with structural compromises: the 0.20% annual asset drag on the free plan erodes compounding over time, the 0.75% FX fee penalizes US stock buyers, and the inability to transfer shares out locks your portfolio to the platform.
If you reside in one of its 8 supported European nations and want a low-maintenance smartphone app to deposit €100 to €500 monthly into diversified UCITS ETFs, BUX offers an accessible workflow. However, if you actively trade US single stocks, require complex analytical charts, or want the freedom to transfer your share certificates to an alternative broker in the future, lower-cost international alternatives will serve your long-term goals better.
BUX is a wholly owned subsidiary of ABN AMRO Bank N.V., one of the largest banking institutions in the Netherlands. ABN AMRO completed the acquisition of BUX in 2024, providing financial backing while maintaining BUX as a standalone digital investment brand.
BUX generates revenue through monthly subscription fees on its Plus (€2.99) and Prime (€7.99) plans, a 0.20% annual variable service fee on its Basic tier, order commissions on standard market trades, a 0.20% to 0.75% currency conversion markup on US stocks, and securities lending revenue splits.

Institutional backing improved following the complete acquisition of BUX by Dutch banking group ABN AMRO in 2024. Cash balances sit with ABN AMRO Clearing Bank N.V., qualifying for the statutory Dutch Deposit Guarantee Scheme (DGS) up to €100,000 per depositor. Investment assets held in the separate custody vehicle qualify for the Dutch Investor Compensation Scheme (ICS) up to €20,000 if fraud or custody insolvency arises.
The significant regulatory blemish on BUX is a formal enforcement action from late 2024. The AFM levied a €1.6 million fine against BUX B.V. on November 18, 2024, published in March 2025, for historic breaches of the national inducement prohibition (provisieverbod). The regulator found that paying financial influencers and running refer-a-friend cash rewards between 2019 and 2023 incentivized sign-ups against client interests, an issue BUX ceased before the ruling took formal effect.
Bottom line: BUX offers regulated Dutch supervision and credible bank ownership, though a sizable 2024 AFM marketing penalty highlights historical compliance lapses.
“Backing from ABN AMRO provides balance sheet reassurance, yet the AFM inducement fine remains a notable compliance watchpoint.”
The critical trade-off centers on portability and securities lending. BUX offers an optional stock lending program: it does not lend out your shares by default, but once you activate it in the app, your holdings may be loaned to market participants in exchange for monthly revenue splits. Basic and Plus clients receive 32.5% of the gross lending rate on stocks and Prime clients receive 45.5%, with loans over-collateralized at 105% in government bonds to mitigate default. The biggest drawback for long-term investors is transferability: BUX does not facilitate in-specie share transfers out of its platform. If you decide to leave BUX, you must liquidate all holdings to cash, potentially triggering taxable capital gains events.
Bottom line: BUX isolates your assets soundly via a Dutch foundation, but locks you in by barring outgoing share transfers.
“Stichting BUX Custody prevents creditor exposure, but the inability to move shares out remains an exit barrier for wealth builders.”
The hidden catch on the Basic plan is the variable service fee. BUX assesses a 0.20% annual charge on your invested assets, billed monthly from your cash balance regardless of whether you trade. On an average portfolio balance of $28,000, this recurring custody charge subtracts roughly $560 over a ten-year holding horizon. Moving to BUX Plus eliminates this percentage fee on portfolios below €250,000, but introduces a fixed €35.88 annual subscription instead.
Currency conversion creates another substantial layer of cost for European investors buying Wall Street assets. BUX Basic charges a 0.75% FX markup on all US dollar trades. On $46,000 worth of lifetime buys in our baseline model, that spread conversion extracts $345. Furthermore, uninvested cash earns 0% interest on Basic, meaning idle funds suffer from inflation unless you upgrade to paid subscription tiers.

In our standardized ten-year scenario starting with $10,000 and depositing $300 monthly across 121 orders, BUX Basic costs roughly $1,041.73 in total. Trade commissions for US market orders at €0.99 ($1.13) add $136.73, or $0 if executed strictly via recurring Investment Plans. The largest cost component is the 0.20% annual variable service fee, consuming $560 over a decade on an average invested balance of $28,000. Foreign exchange conversion at 0.75% on $46,000 in gross dollar asset purchases adds another $345.00. Investors buying exclusively domestic European assets or upgrading to BUX Plus (€2.99 per month) alter these trade-offs, but the basic tier imposes meaningful percentage-based asset drag.
Bottom line: BUX offers cheap ticket fees for automated plans, but its 0.20% asset fee and 0.75% FX markup make holding US portfolios costly over time.
“Zero-commission investment plans lure beginners, but the 0.20% annual asset drag erodes long-term buy-and-hold returns.”
However, market depth narrows considerably compared to global discount brokers. You cannot trade direct government bonds, corporate debentures, mutual funds, options, or Asian exchanges like Tokyo or Hong Kong. Furthermore, multi-currency balances do not exist: accounts function strictly in euros, requiring immediate currency conversion for every non-euro transaction.
Bottom line: BUX delivers sufficient stock and ETF coverage for everyday European retail investors, but falls short for multi-asset allocators.
“A dependable selection of UCITS ETFs and US blue chips serves passive DCA investors, though absent fixed-income markets cap portfolio versatility.”
The software includes basic portfolio monitoring alongside automated "Investment Plans". You can view your portfolio's all-time performance, today's profit or loss, average purchase prices, and instrument breakdowns. Real-time market quotes are delivered at zero surcharge, and recurring deposits integrate with local instant banking rails like Tikkie in the Netherlands.
However, analytical depth is minimal for active or research-heavy investors. You will not find advanced charting indicators like MACD or Bollinger Bands, technical drawing tools, or complex financial screeners. The web interface serves primarily as an account administration companion rather than a dedicated trading desktop, and BUX does not offer programmatic API connectivity or virtual demo accounts for practice.
Bottom line: BUX provides a clean mobile environment for automated buying, but serious analytical tools are absent.
“The app excels at simplicity for monthly ETF contributors, but active market analysts will find the charting far too basic.”
Execution flexibility remains constrained by missing advanced order types. You cannot set trailing stop orders, OCO (one-cancels-the-other) combinations, or stop-limit orders. Furthermore, trading is confined to official European and US market hours: pre-market and after-hours trading sessions are unavailable, leaving you unable to react to earnings announcements released outside official exchange windows.
Bottom line: BUX provides clean, PFOF-free trade routing for standard orders, but advanced order conditional controls are absent.
“Prohibiting PFOF aligns execution with client interests, though active participants will miss trailing stops and pre-market liquidity.”
The prominent account limitation is the complete absence of local tax wrappers. BUX does not offer specialized tax-sheltered accounts like the French PEA, Italian PIR, or UK ISA equivalents. Moreover, BUX does not automatically withhold local capital gains taxes or financial transaction taxes for Belgian or Italian residents, leaving you to manually declare transactions to your national tax agency using the annual overview. Automated dividend reinvestment plans (DRIP) are also missing.
Bottom line: BUX streamlines US dividend withholding, but offers zero local tax-sheltered wrappers and requires manual tax filing.
“Automatic W-8BEN relief protects US dividend yields, but lack of tax wrappers like the French PEA is a tax disadvantage for European savers.”
Bottom line: BUX provides swift, zero-fee euro transfers, but lacks multi-currency support and card deposit options.
“Free SEPA and Tikkie rails ensure convenient domestic euro movement, but forced currency conversion remains restrictive for US stock holdings.”
However, experienced investors will quickly notice the absence of institutional research tools. BUX does not provide analyst reports from firms like Morningstar, Refinitiv, or S&P Capital IQ. You cannot review deep historical financial statements, consensus earnings estimates, or discounted cash flow valuation models. Research features are strictly introductory, meaning in-depth equity analysis must be conducted on external platforms.
Bottom line: BUX provides accessible learning guides for beginners, but lacks the analytical research depth demanded by active stock pickers.
“Educational articles fulfill basic onboarding duties well, but the complete lack of institutional research data limits fundamental stock analysis.”
The primary customer service drawback is the absence of telephone assistance for everyday retail accounts. If you encounter an urgent transaction issue or an account lock, you cannot speak directly with a telephone representative. However, regulatory dispute protections are firmly established: if an internal complaint remains unresolved, European clients can escalate matters directly to KiFiD (Klachteninstituut Financiële Dienstverlening), the official Dutch financial dispute body.
Bottom line: BUX delivers solid digital chat assistance across six languages, though lack of phone support limits urgent escalations.
“Multilingual digital chat serves day-to-day app queries dependably, while access to KiFiD provides dependable statutory complaint recourse.”
BUX Basic charges €0 per month, a 0.20% annual fee on invested assets, €0.99 for US stock orders, €3.99 for European share orders, and a 0.75% foreign exchange markup. Automated monthly Investment Plan orders execute without transaction commission on all plans.
You cannot transfer shares out of BUX to an external brokerage firm. BUX does not support outgoing in-specie portfolio transfers. If you decide to switch brokers, you must sell your positions for cash and withdraw the proceeds to your linked bank account.
BUX pays variable interest on uninvested euro cash balances on its paid subscription plans, offering up to 1.50% on BUX Plus and up to 1.75% on BUX Prime for balances up to €100,000. The free BUX Basic plan does not pay interest on cash.
BUX Zero was the former brand name of BUX's flagship zero-commission trading application. Following the corporate acquisition by ABN AMRO and a brand refresh, the platform retired the "Zero" suffix and currently operates simply under the name BUX.
