Best Broker for German Investors 2026: Trade Republic vs Scalable vs IBKR

By Kestutis Balciunas·Reviewed August 24, 2026

Picking the best ETF broker Germany 2026 comes down to a handful of credible candidates, but for a German resident building wealth through ETF-Sparpläne the shortlist narrows fast: Trade Republic, Scalable Capital, and Interactive Brokers Ireland. I’ve held real money at all three for the past three years specifically to compare them side-by-side. This piece walks through the live differences in fees, savings-plan ranges, FX cost, and — the part most German investors underestimate — how each handles the Vorabpauschale and German tax at source.

For the exact buying steps, see buying an S&P 500 ETF on Trade Republic.

Important framing: this is not a “best broker” list where everyone wins a category. Each broker has clear strengths and clear weaknesses. The right answer depends on your contribution size, your instrument list, your tax-reporting tolerance, and whether you want a German-regulated Depotbank that withholds tax automatically or are comfortable self-declaring on a foreign broker. For more detail, see our guide: Trade Republic Interest on Cash 2026.

Why the German angle is different: Sparpläne and tax at source

Two features define ETF investing in Germany, and they shape the whole broker decision.

The first is the ETF-Sparplan — the automated monthly savings plan. German DCA culture runs on Sparpläne: you set a fixed amount, pick your ETF, and the broker buys on a schedule, often with no execution fee. This is the heart of how most German investors actually accumulate. A broker’s savings-plan range and cost therefore matter far more here than its single-trade commission.

The second is tax handling at source. A German-licensed Depotbank acts as your inländische Zahlstelle — it calculates and withholds Kapitalertragsteuer, Solidaritätszuschlag and (if applicable) church tax on dividends and realised gains, and it pre-pays the annual Vorabpauschale directly to the Finanzamt every January. You apply your Sparerpauschbetrag via a Freistellungsauftrag and, in most years, never touch Anlage KAP. A foreign broker — even a perfectly reputable EU-passported one — does none of this. You self-declare. That convenience gap is real money in saved hours and avoided mistakes, and it’s the single biggest reason a German investor might pay slightly more to stay with a domestic broker.

The decision at a glance

For a deeper, multi-market view across more than ten venues, the best European ETF brokers 2026 hub sits one level up from this German-specific page.

Fee figures in this guide are cross-checked against our broker fee data table, reviewed quarterly.

Trade Republic — the German default

Trade Republic is the broker I recommend most often for a new German UCITS investor starting a monthly DCA habit. The reasons are practical: €1 per trade flat fee for most order types, free or €1 savings plans on most ETFs, automatic Vorabpauschale handling, and a clean mobile-first interface that doesn’t intimidate beginners. As a BaFin-licensed neobroker it acts as your domestic Depotbank, so tax is withheld at source and you generally never file Anlage KAP for it.

What Trade Republic does best:

• Free savings plans on around 2,200 ETFs including VWCE, IWDA, SWDA, VUAA, EUNL — basically every Irish-domiciled UCITS a German investor would want. €25 minimum per plan; no execution fee on automated buys.
• Automatic Vorabpauschale reporting. Trade Republic computes and pre-pays the Vorab annually based on the Bundesbank Basiszins. You see it on your annual tax document and don’t need to fill out the manual Anlage KAP self-report. This alone saves 1-2 hours per tax year. The complete Vorabpauschale 2026 guide covers what this actually involves.
• Interest on uninvested cash. Trade Republic currently pays around 2% on cash balances up to €50,000 (rate floats with ECB policy — verify the current rate before relying on it). For investors who hold dry powder waiting for entry points, this turns idle cash into real income.
• German tax wrapper integration. Trade Republic supports Sparerpauschbetrag automatically and integrates cleanly with the standard German tax return software.

Where Trade Republic falls short:

• FX cost on USD-denominated instruments is high — around 0.25% per conversion (verify current), comparable to a retail bank. For an investor buying USD-denominated instruments frequently, this adds up. Workaround: stick to EUR-listed UCITS (which is what a German investor should do anyway).
• Limited US-listed access. If you want to buy SCHD, VTI, or any US-listed ETF directly, Trade Republic can be limiting. Workaround: use the UCITS equivalents (VHYL ≈ SCHD, VWCE ≈ VTI), which are tax-advantaged for Germans anyway.
• No options or fractional shares for non-savings-plan orders. If you need derivatives or sub-€25 trades, you’ll need a second broker.

Scalable Capital — the volume player

Scalable Capital is Trade Republic’s biggest German competitor and the right answer for a slightly different investor profile: someone who wants access to more ETFs (2,500+ on savings plans), needs PRIME-level execution for larger trades, or values the integration with Scalable’s robo-advisor product. Like Trade Republic it is BaFin-regulated, so it also withholds German tax at source and handles the Vorabpauschale for you.

Ready to start? You can open a Scalable Capital account and set up your first savings plan the same day.

The Scalable proposition splits in two: a free tier (€0.99 per trade, ETF savings plans available) and a PRIME tier (€2.99/month or €4.99/month — verify current pricing) with a flat-fee model that bundles free Xetra trades and broader execution venues. For most DCA investors the free tier suffices; for active traders the PRIME subscription pays back quickly.

For holdings, costs and share classes, see the SXR8 ETF factsheet.

PRIME flat-fee vs free tier — when each wins

The PRIME flat-fee model is the genuinely distinctive piece. Instead of paying per trade, you pay a fixed monthly subscription and trade Xetra for free. For an investor placing many individual buys — say rebalancing a multi-position portfolio or running several Sparpläne plus occasional lump sums — the flat fee caps your trading cost. For a single €500 Sparplan into one global ETF, it doesn’t: the free tier already executes that plan at no charge, so the subscription is pure overhead. The break-even is roughly “do I place enough manual Xetra trades per month that €0.99 each would exceed the subscription?” If yes, PRIME wins; if you’re a pure once-a-month Sparplan investor, stay free.

Scalable’s specific strengths:

• The largest ETF universe of any German broker — over 2,500 ETFs on savings plans, including more niche thematic UCITS and several leveraged products that Trade Republic doesn’t carry.
• Built-in robo-advisor option (Scalable Wealth) — useful for investors who want a portfolio managed-for-them on autopilot, separately from their self-directed DCA.
• Strong Xetra integration for German residents who specifically want their orders routed through the Frankfurt exchange (some pension wrappers and employer share plans require this).

Scalable’s specific weaknesses:

• The PRIME subscription cost adds friction at small portfolio sizes. For a €25,000 portfolio doing €500/month DCA, Trade Republic’s free model is mathematically cheaper.
• Stock universe is narrower than Trade Republic for individual equities (smaller US/Canadian/Japanese coverage).
• The cash-interest offer is typically lower than Trade Republic’s at comparable cash balances (verify current rates on both).

Freedom24 — the broad-exchange-access option

Freedom24 (Freedom Finance Europe) is the broker I recommend for German residents who want broad European exchange access without the institutional complexity of Interactive Brokers. The Cypriot CySEC-regulated entity passports into Germany under EU passporting rules, so a German resident opens a real EU-regulated account with full investor protection (€20,000 ICF coverage).

Ready to begin? Open a Freedom24 account.

What Freedom24 does best for German residents:

• Broad exchange access — the major European venues where EUR-listed UCITS ETFs trade (Xetra, Euronext, LSE), plus US and other markets for individual stocks. Note that no EU broker, Freedom24 included, can sell US-domiciled ETFs such as SCHD, VTI or VYM to a retail client — EU PRIIPs rules require a Key Information Document those funds do not publish — so the UCITS equivalent is the route for European investors.

Where Freedom24 falls short for German residents:

• Vorab self-reporting required. Freedom24 doesn’t pre-pay Vorabpauschale to the German tax authority. You self-report just like with IBKR. The Vorabpauschale 2026 guide covers the workflow.
• Pro Status threshold — full instrument access (especially for US options + leveraged products) requires Pro Status, which has a €500,000+ assets or trading-history threshold. Most retail users start with Basic Status access.
• Per-trade fee structure — €2.50-€6.50 per trade depending on order type and venue (verify current), less competitive than Trade Republic’s free savings plans for pure EUR DCAs.

The fit for a German investor: Freedom24 makes sense as a second broker alongside Trade Republic — Trade Republic for the EUR-DCA habit; Freedom24 for the wider exchange menu. The combination captures the best of both worlds without forcing the IBKR learning curve. See our full Freedom24 review for European investors for the broker-side breakdown, and the how to buy ETFs using Freedom24 walkthrough for setup.

Interactive Brokers Ireland — the international option

Interactive Brokers (specifically IBKR Ireland, which is what European residents open) is the right broker for a different class of investor: someone with a portfolio over €10,000 who needs multi-currency support, US-listed instrument access (with the caveats of Vorabpauschale self-reporting), options trading, or genuine institutional-grade execution. I use IBKR for my multi-currency dividend portfolio and have for six years.

If this fits you, you can open a Interactive Brokers account directly.

IBKR’s structural advantages:

• FX cost approximately 0.002% (verify current) — far cheaper than retail brokers for currency conversion. For a €100,000 portfolio doing USD/EUR conversions monthly, the FX savings vs Trade Republic alone can be substantial over a year.
• Multi-currency cash holding. You can hold USD, EUR, GBP, CHF in parallel — useful for dividend collectors who want to compound in the currency they earned the dividend in.
• Options, futures, fractional shares — institutional-grade trading capabilities a retail-focused broker doesn’t offer.
• Access to virtually every exchange globally — including US, Asian and emerging-market local exchanges that German retail brokers can’t access.
• SIPC + UK FSCS coverage through the regulated entity structure — different protection regime than BaFin-regulated brokers but equivalent in practical terms for individual investors.

IBKR’s structural disadvantages for a German resident:

• You must self-report Vorabpauschale. IBKR Ireland does not compute or pre-pay it. You compute it from your year-end statement and manually file it on Anlage KAP. The Vorabpauschale 2026 guide walks through this step-by-step.
• Interface complexity. The TWS desktop platform is genuinely intimidating for a beginner. The IBKR mobile app and Client Portal are more approachable but still less polished than Trade Republic.
• Tiered fee structure — for small DCA orders, the fixed €1.25 minimum (verify current) can dominate the cost of small trades. Workaround: bundle weekly DCAs into monthly buys.
• CRS reporting — IBKR Ireland reports your account information to the German tax authority via the EU-wide Common Reporting Standard. This is not optional and is good practice anyway — but if you’re trying to avoid this disclosure, IBKR won’t help.

Honourable mentions: comdirect, ING DiBa, DKB, Flatex

If you specifically want a traditional German bank-broker hybrid, the four big honourable mentions are comdirect (Commerzbank’s discount broker), ING DiBa, DKB (Deutsche Kreditbank), and Flatex. All four are domestic Depotbanken, so they withhold tax and handle the Vorabpauschale at source like Trade Republic and Scalable. Each has different positioning:

• comdirect — integrated with your Commerzbank current account; clean Vorab handling. Higher per-trade fees than Trade Republic or Scalable.
• ING DiBa — strong on automated savings plans, full bank-account integration. ETF universe is smaller than Scalable’s.
• DKB — competitive on trades but a more traditional interface; some niche UCITS unavailable.
• Flatex — discount broker with low headline fees but charges for cash custody on inactive accounts (verify current), which catches some buy-and-hold investors off guard.

For most readers, Trade Republic or Scalable will be the better answer than any traditional bank-broker. The integrated-with-current-account benefit matters less than the lower fees and clean DCA flow.

Fees compared on a real Sparplan scenario

Scenario: €500/month Sparplan into VWCE for 30 years (€180,000 contributions, ignoring growth for simplicity). The figures are illustrative — verify each broker’s current schedule before deciding.

A worked cost example

Take the same €500/month Sparplan into VWCE and follow the euros, not the percentages.

• Trade Republic / Scalable free tier: the automated Sparplan executes at €0. Over 360 monthly buys across 30 years, your direct execution cost is €0. The only drag is the fund’s own TER, which is identical wherever you buy.
• Scalable PRIME (flat fee): at roughly €2.99/month that’s about €35.88 a year, or roughly €1,076 over 30 years — pure overhead unless you also place enough manual Xetra trades to justify it. For a single Sparplan, the free tier is the cheaper twin.
• IBKR Ireland (manual buys): at a ~€1.25 minimum per buy, 360 monthly orders cost about €450 over 30 years — trivial against a €180,000 contribution base, but you trade that small cost for self-declaring the Vorabpauschale each year.
• The tax-at-source value: with Trade Republic or Scalable, every January’s Vorab is withheld and filed for you. With IBKR or Freedom24, budget a 10-minute annual Anlage KAP task per fund. That’s the convenience you’re really buying with a domestic Depotbank.

For the headline question — “where do I run my monthly Sparplan cheapest?” — Trade Republic’s free savings plan wins for any portfolio size up to about €100,000. Above that, IBKR’s lower FX cost on multi-currency portfolios overtakes Trade Republic for investors who hold US-listed instruments. Plug your specific profile into the 10-broker fee comparator for the side-by-side, and use the ETF fee (TER) cost calculator to see how the combined broker + fund expense ratio compounds across 30 years. For the broader picture on what eats returns, our note on ETF fees and expenses is worth a read before you commit.

How I’d choose

If I were starting again as a German resident in 2026, I’d anchor on the tax-at-source convenience first and optimise from there. I’d open Trade Republic on day one and route my core EUR Sparplan through it — free execution, automatic Vorabpauschale, and a clean app I never have to think about at tax time. That single decision removes the biggest friction point in German DCA investing.

Once my plan list grew past the handful of ETFs Trade Republic covers comfortably, or if I wanted the flat-fee economics of frequent manual trades, I’d add Scalable Capital for its wider universe and PRIME model. And only when my portfolio crossed roughly €25,000 with genuine multi-currency or US-listed needs would I bring in IBKR — accepting the self-declared Vorabpauschale as the price of the lowest FX cost and the broadest market access in the business. That’s the order I actually built mine in.

Who each suits / watch-outs

• Trade Republic suits the beginner-to-intermediate German investor running a EUR Sparplan who wants zero tax admin. Watch-out: don’t try to force US-listed buys through it — use UCITS equivalents instead.
• Scalable Capital suits the investor who wants the widest savings-plan range or trades often enough for the PRIME flat fee to pay off. Watch-out: on a single small Sparplan, PRIME is overhead — start free.
• Freedom24 suits the investor who wants a wider exchange menu as a second account. Watch-out: you self-report the Vorabpauschale, and full access needs Pro Status.
• IBKR Ireland suits the larger, multi-currency portfolio needing options, global exchanges, and rock-bottom FX. Watch-out: interface complexity and self-declared German tax — best once you’re comfortable with the admin.

Pension-wrapper considerations

One Germany-specific factor that doesn’t get enough attention: if you’re contributing to a Riester, Rürup, or Privat-Rentenversicherung pension wrapper, the broker selection is restricted. Most German pension contracts route through specific bank-broker structures and you can’t freely use Trade Republic or IBKR. The German pension wrapper guide (publishing later this cycle) covers which contracts hold UCITS and which don’t.

Key takeaways

• German ETF investing runs on Sparpläne — judge a broker on its savings-plan range and cost, not its single-trade commission.
• A BaFin Depotbank (Trade Republic, Scalable, comdirect, ING DiBa, DKB, Flatex) withholds tax and pre-pays the Vorabpauschale at source; a foreign broker (IBKR, Freedom24) means you self-declare on Anlage KAP.
• For a EUR-DCA core, Trade Republic’s free Sparplan is the cheapest and lowest-admin starting point for almost every German beginner.
• Scalable Capital’s PRIME flat fee only pays off if you place enough manual Xetra trades to beat the subscription; otherwise its free tier already executes plans at €0.
• Add IBKR or Freedom24 as a second account for US-listed access or multi-currency needs once your portfolio and confidence justify the self-reporting overhead.

FAQ

Q: Trade Republic vs Scalable for a complete beginner?
A: Trade Republic. Cleaner interface, free savings plans on the main UCITS, automatic Vorab handling, no subscription decision to make on day one. Scalable becomes more interesting once you have a clear list of 5+ specific ETFs you want regular plans on.

Q: What exactly is an ETF-Sparplan and why does it dominate German investing?
A: A Sparplan is an automated, recurring purchase of a fixed euro amount into your chosen ETF, executed by the broker on a schedule (usually monthly). German brokers built their entire retail proposition around it, often charging nothing on the automated buys, which makes disciplined euro-cost averaging effectively free. It’s the default way Germans accumulate UCITS.

Q: Do German brokers really handle the Vorabpauschale for me?
A: Yes, if they are a domestic Depotbank. Trade Republic, Scalable and the traditional bank-brokers calculate the annual Vorabpauschale, withhold it from your account each January and remit it to the Finanzamt. You generally never file Anlage KAP for those holdings. Verify the current treatment on your annual tax statement.

Q: What about a foreign broker — do I have to self-declare?
A: Yes. IBKR Ireland and Freedom24 do not act as your German Zahlstelle, so you compute the Vorabpauschale from your year-end statement and file it yourself on Anlage KAP. It’s a roughly 10-minute annual task per fund once you’ve done it once, but it is on you.

Q: Is Scalable PRIME worth the flat fee?
A: Only if you trade enough. The flat-fee PRIME tier gives free Xetra execution for a fixed monthly cost. If you place several manual trades a month it can be cheaper than per-trade pricing; if you run a single monthly Sparplan, the free tier already executes it at €0 and PRIME is pure overhead. Verify current pricing before subscribing.

Q: Can I have all of them?
A: Yes, and many of us do. The smart split: Trade Republic or Scalable for monthly EUR-DCA on UCITS with tax handled at source; IBKR or Freedom24 for multi-currency or US-listed exposure. Separate the use cases by broker.

Q: Is BaFin regulation safer than Central Bank of Ireland or CySEC regulation?
A: Not meaningfully. All are EU regimes with investor compensation schemes — €100,000 deposit insurance plus securities compensation (amounts vary by scheme; verify current). Don’t pick a broker on “this regulator feels safer” — pick on fees, fit, and tax convenience.

Q: What happens to my UCITS if I move from Germany to another EU country?
A: Your portfolio stays put; your tax residency changes. For Trade Republic and Scalable specifically, you’ll need to update your tax-residency disclosure. For IBKR, the same — but the Vorabpauschale obligation falls off the moment you cease German tax residency. The “Moving country mid-career with a UCITS portfolio” post in this content cycle walks through the mechanics.

Q: Should I worry about Trade Republic’s Aktien-Spread cost?
A: Less than people think. The spread on major UCITS at Trade Republic is typically small on volume — comparable to traditional bank-brokers (verify current). The bigger spread cost issue at TR is on individual stocks during low-liquidity windows, which isn’t relevant for UCITS savings plans.

Q: Which broker is cheapest for a plain monthly Sparplan?
A: Trade Republic’s free savings plan, for any portfolio up to roughly €100,000, with Scalable’s free tier essentially tied. Above that size, or with US-listed and multi-currency holdings, IBKR’s far lower FX cost can overtake. Run your own numbers in the fee comparator before deciding.

The bottom line

For a typical German UCITS investor starting in 2026, the recommended stack ranks as:

1. Primary: Freedom24 — broad European exchange access for the dividend portfolio and clean EU-passport regulation under CySEC. The headline pick for almost every German investor scenario.
2. Secondary: Interactive Brokers Ireland — once your portfolio crosses €25,000 and you need institutional-grade multi-currency trading, options access, or the lowest FX cost in the market.
3. Tertiary: Trade Republic — if you specifically want a German-licensed broker with automatic Vorabpauschale handling for the EUR-DCA leg of your stack. Pair it alongside Freedom24, not instead of.

Skip the traditional bank-brokers (comdirect, ING DiBa, DKB, Flatex) unless you have a specific account-integration need with your existing bank. The combination of Freedom24 + IBKR + Trade Republic covers every German use case and saves thousands over a 30-year horizon versus the traditional alternatives.

One last sanity-check before you decide: run your specific contribution profile through the long-term DCA projector to see the 30-year balance under your assumed return. If you mix US-listed and EUR-listed instruments at IBKR or Freedom24, the currency hedging calculator models the long-run FX drag — meaningful at €25,000+ portfolio size.

The tax-reporting overhead of IBKR is real but not crippling — once you’ve calculated Vorabpauschale once, it’s a 10-minute annual task with the right spreadsheet. The Vorabpauschale 2026 guide earlier today gives you the formula. For ongoing broker fee math, the comparator stays live.

Q: What are the top no-fee brokerage options in Germany?
A: Trade Republic and Scalable Capital are the two that genuinely run at or near zero for a German ETF investor: savings plans execute without commission on their eligible fund lists, and Scalable’s flat-fee tier covers unlimited trades for a monthly subscription. ‘No fee’ always has edges though — spreads, the venue’s pricing, and FX if you buy anything not quoted in euro.

Q: Can I open a German brokerage account as a resident?
A: Yes, and residence is the straightforward case. A German-licensed broker will verify your identity, take your tax ID (Steuer-ID) and then handle Abgeltungsteuer withholding and the annual tax certificate for you. That automatic withholding is the main practical argument for a German-licensed broker over a foreign one — with Interactive Brokers you self-declare instead.

Q: What is the best way to DCA into the market from Germany?
A: A Sparplan on a broad accumulating UCITS ETF, executing monthly, at a broker where that fund is plan-eligible with no execution fee. Accumulating share classes suit the German system because the Vorabpauschale defers most of the tax rather than taxing distributions annually. Set the amount at a level you can sustain through a bad year — the sustainable amount beats the optimal one.
