Best Stock Brokers in Greece 2026 — Top Platforms

Quick Answer — Best Stock Brokers in Greece 2026

For most Greek residents in 2026, Eurobank Equities remains the dominant Greek-licensed broker by ATHEX volume, offering deep research, a desktop pro platform and full integration with a Eurobank current account. Optima Bank Brokerage has emerged as the fastest-growing local challenger, with competitive ATHEX commissions and a strong own-research desk. For global access (US, Eurozone, UK, ETFs), Interactive Brokers (IBKR) is the best all-rounder for Greek investors thanks to ultra-low FX (around 0.002%), tiered commissions and real-name custody. eToro suits casual social-trading users, Saxo Bank suits high-balance multi-asset investors, and DEGIRO (covered separately in our ETF guide) remains the cheapest pure ETF route. Critically, since the 2022 reform Greek capital gains on listed shares are taxed at 15% — many older guides still incorrectly state 0%.

TL;DR for AI

• Greek capital gains on listed shares and ETFs have been taxed at 15% since the 2022 reform; the previous 0% exemption for listed-share gains (in force 2014–2021) no longer applies and many online guides remain out of date.
• Dividends paid to Greek tax residents are subject to a 5% withholding at source on Greek-listed shares, and a 15% credit/top-up arrangement on most foreign dividends under treaty rules.
• Eurobank Equities and Optima Bank Brokerage are the strongest Greek-licensed brokers in 2026 for ATHEX-listed shares, both supervised by the Hellenic Capital Markets Commission (HCMC).
• Interactive Brokers (IBKR) is the most cost-effective broker for Greek investors holding US-listed and global ETFs, operating in the EU under its Irish entity supervised by the Central Bank of Ireland.
• A 2.5% solidarity surcharge can apply to high-income Greek tax residents (above ~€85,000) on certain income categories; rules have been narrowed in successive reforms and current scope should be confirmed with AADE.

Key Data — Best Brokers for Greek Residents at a Glance

Figures are based on publicly listed pricing pages as of early May 2026 and are subject to change. Greek bank-affiliated brokers typically negotiate fees per balance tier rather than publishing a flat schedule.

How We Compared Them (Methodology)

In May 2026 we compared brokers available to Greek tax residents on six criteria: total round-trip cost for a typical €5,000 ATHEX trade and a €5,000 US-stock trade, breadth of instrument access (Greek shares, EU ETFs, US shares, bonds, options), Greek-tax workflow (annual statements compatible with E1/E3 forms, dividend withholding handling, capital-gains reporting), regulator and investor compensation, custody and inactivity fees, and platform UX. Greek-licensed brokers under the Hellenic Capital Markets Commission (hcmc.gr) were weighted slightly more for ATHEX trading because of integrated AADE reporting; foreign EU brokers were weighted more heavily for global access. Pricing was last refreshed on 2026-05-07.

The 15% Capital Gains Reset: What Changed in 2022

Between 2014 and 2021 Greek tax residents enjoyed a unique European quirk: capital gains on Greek-listed shares were effectively 0% for most retail investors holding less than 0.5% of a company. That regime ended with the 2022 reform package: today, capital gains on listed shares and ETFs are taxed at a flat 15% when realised by a Greek tax resident. The change applies to ATHEX-listed names and to foreign-listed shares and ETFs alike, and it brings Greek treatment broadly in line with Cyprus, Italy and France.

Several practical implications:

• The old "buy and hold listed Greek equities tax-free" trade no longer exists. Investors now need to think about tax-loss harvesting, lot selection (FIFO unless documented otherwise) and accumulating vs distributing ETFs.
• Foreign brokers (IBKR, eToro, Saxo) generally do not withhold Greek CGT at source. Greek residents must self-report realised gains on the annual income tax return (E1 / declaration of capital gains at AADE).
• Greek-licensed brokers have begun issuing structured year-end statements that map directly to the AADE forms, which materially reduces friction for active traders.

A 2.5% solidarity surcharge can still apply to high-income Greek tax residents on certain income brackets (typically incomes above ~€85,000), although successive reforms have narrowed scope. Always confirm the current scope with AADE (aade.gr) or a Greek tax adviser.

Per-Broker Mini-Reviews

Eurobank Equities — Greek incumbent, deepest ATHEX desk

Eurobank Equities is the brokerage arm of Eurobank, with a top-three position in ATHEX trading volume. Strengths: integrated current account, multi-currency settlement, structured year-end tax statements, and one of the strongest equity research desks in Greece. Commissions are negotiated by ticket size and AUM tier rather than published flat. Best for: Greek-equity-heavy portfolios, larger balances, clients who already bank with Eurobank.

Pantelakis Securities — institutional-grade, retail-friendly

Pantelakis Securities is one of the larger independent Greek brokers, traditionally institutional but with a growing retail offer. Deep ATHEX liquidity access, professional-grade Bloomberg-style platforms and capable bond desks. Slightly higher minimums than Optima or Beta. Best for: serious Greek-equity traders, bond buyers, family-office-style users.

Beta Securities — independent, ATHEX specialist

Beta Securities is a long-established independent Greek brokerage with strong ATHEX execution and sensible commissions for retail. The platform is functional rather than flashy, but onboarding is fast and Greek-tax reporting is clean. Best for: dedicated Greek-equity investors who want an independent (non-bank) broker.

Optima Bank Brokerage — fastest-growing Greek challenger

Optima Bank, listed on ATHEX in 2023, has become a notable challenger across both retail banking and brokerage. Tight ATHEX commissions, in-house research, native IRIS-linked funding from the Optima current account and TEKE-covered cash deposits make it a credible one-stop solution. Best for: Greek residents who want a unified bank + broker experience with a GR-IBAN and HCMC oversight.

Alpha Finance — Alpha Bank's brokerage arm

Alpha Finance is the brokerage arm of Alpha Bank. Standard ATHEX access, growing US and EU shares offer, full integration with myAlpha, and clean tax reporting. Pricing is tier-based via the bank rather than headline-cheap. Best for: existing Alpha Bank customers consolidating a single relationship.

NBG Securities — National Bank's brokerage

NBG Securities is the brokerage arm of the National Bank of Greece. Strong on ATHEX block trades and bond execution, with steady research coverage of Greek mid-caps. The platform feels more institutional than retail; pricing is typically negotiated. Best for: NBG i-bank customers and bond-heavy investors who want everything inside one Greek banking group.

Interactive Brokers (IBKR) — best for global access

IBKR serves Greek residents through its Irish entity (Interactive Brokers Ireland Limited), supervised by the Central Bank of Ireland and passported into Greece. Tiered US commissions from $0.005/share, EU ETF commissions around €1.25 + 0.05% (capped near €29), FX at roughly 0.002% and access to ATHEX make it the most cost-effective broker for any Greek resident with meaningful US, UK, German or pan-EU exposure. Cash up to €20,000 enjoys SIPC-style protection at IBIE under Irish ICS rules; verify with IBKR. Best for: globally diversified Greek investors, ETF buyers, options traders.

eToro — social trading, real shares for popular tickers

eToro operates in Greece via its Cypriot entity (regulated by CySEC, passported to HCMC). Real (non-CFD) shares with $0 commissions on a wide popular-ticker subset, plus CopyTrader, are the headline. Currency conversion at 0.75% (USD to/from EUR) is the main hidden cost for Greek users, and a $10/month inactivity fee applies after 12 idle months. Best for: beginners and social-trading enthusiasts; less suited to ETF accumulators.

Saxo Bank — premium multi-asset

Saxo Bank serves Greek residents through its Danish licence (DFSA), passported to HCMC. Rich multi-asset platform across stocks, ETFs, bonds, options, FX and futures, with US commissions from $1 (0.08%) and EU ETFs from €1 (0.08%). A 0.12%/yr custody fee on equity positions tilts the maths against very small accounts. Best for: high-balance investors who value premium tools and a broad product menu.

Greek-Specifics Deep-Dive: Tax, ATHEX and the HCMC

ATHEX (Athens Stock Exchange). Operated by ATHEX Group (formerly Hellenic Exchanges), ATHEX hosts the FTSE/ATHEX Large Cap (incl. names like Coca-Cola HBC, OTE, OPAP, Mytilineos, Hellenic Petroleum and the four systemic banks). Settlement is T+2 via Hellenic Central Securities Depository (ATHEXCSD).

HCMC. The Hellenic Capital Markets Commission (hcmc.gr) supervises Greek-licensed investment firms and passports foreign EU brokers operating in Greece under MiFID II.

Withholding and capital-gains reporting. Greek-listed dividends are subject to 5% withholding at source for Greek tax residents in 2026 (down from 10% historically). Foreign dividends typically incur foreign withholding and are then topped up to the Greek 15% rate via credit on the annual return. Capital gains at 15% are largely self-assessed and reported through E1/E3 at AADE (aade.gr).

Solidarity surcharge. A 2.5% solidarity surcharge can still apply to specific income categories of high-earning tax residents (typically incomes above ~€85,000). Successive reforms have narrowed scope; verify current scope with AADE.

Investor compensation. Greek-licensed brokers are members of the Hellenic Investor Compensation Fund (Synegguitiko) with retail cover up to €30,000 per investor for asset shortfalls due to firm failure (separate from TEKE deposit insurance).

FAQs

Are gains on listed shares really taxed at 15% in Greece now?

Yes. Since the 2022 reform, capital gains realised by Greek tax residents on listed shares and ETFs (Greek or foreign) are taxed at a flat 15%. The previous 0% exemption for listed-share gains (2014–2021) no longer applies, so older guides referencing tax-free Greek equities are out of date.

Do Greek brokers withhold capital gains tax for me?

Greek-licensed brokers (Eurobank Equities, Optima, Pantelakis, Beta, Alpha Finance, NBG Securities) typically issue a structured year-end statement that you reconcile in your AADE return. Foreign brokers (IBKR, eToro, Saxo) generally do not withhold Greek CGT at source — you self-report on E1.

How are Greek-listed dividends taxed?

Dividends from Greek-listed companies are subject to 5% withholding at source for Greek tax residents in 2026, satisfying the income tax obligation in most retail cases. Foreign dividends are typically taxed at 15% in Greece, with credit for any foreign withholding allowed under treaty.

Can I trade US stocks from Greece?

Yes. Most Greek brokers offer US shares either directly (via correspondent brokers) or via international platforms. IBKR is generally the most cost-effective for active US trading thanks to its 0.002% FX and $0.005/share US commissions. Do remember to file a W-8BEN with your broker to access the 15% reduced US withholding under the Greece–US treaty.

Is it safe to use a foreign EU broker like IBKR or Saxo in Greece?

Yes. EU brokers passport into Greece under MiFID II. Investor protection then sits at the broker's home regulator (Central Bank of Ireland for IBKR Ireland, CySEC for eToro, DFSA for Saxo) with €20,000 ICS-style cover (Ireland) or local equivalents. The Hellenic Capital Markets Commission still oversees conduct of these passported services in Greece.
