Capital Gains Tax in Europe: How Major Countries Compare

Selling an investment at a profit feels good. The tax bill that follows sometimes does not. Capital gains tax in Europe is not a single, unified system — it is a patchwork of national rules, each with its own rates, exemptions, holding-period logic, and asset-class quirks. If you hold stocks, ETFs, crypto, or funds across multiple countries or currencies, understanding the landscape is essential before you make any disposal decision.

This post compares how several major European countries treat capital gains, highlights the factors that move your effective rate up or down, and explains how accurate record-keeping — especially cost basis — can make or break your tax position.

What "Capital Gains" Actually Means

A capital gain arises when you sell (or otherwise dispose of) an asset for more than you paid for it.

Cost basis is what you originally paid, including any acquisition costs (brokerage commissions, for example). If you bought the same asset in multiple tranches at different prices, you need a method to determine which units you are selling. The most common method in Europe is FIFO (First In, First Out) — the oldest shares are deemed sold first. Some countries allow average cost or specific identification. The method matters because it directly changes your taxable gain.

The table below summarises the general treatment for individual investors on gains from listed equities and standard funds. Crypto and real estate often have separate or modified rules. Treat these as a starting point, not a filing guide.

Reading this table: Rates shown are approximate headline figures for individuals on standard investment gains. They exclude surcharges, local taxes, and special regimes. Cross-border situations (e.g., a Spanish resident holding German ETFs) add treaty layers. Verify everything.

Four Factors That Shift Your Effective Rate

1. Holding Period

Several countries historically rewarded long-term holding with lower rates or taper relief. While many EU countries have moved toward flat rates regardless of holding period, some still distinguish — and the rules change. Always check whether how long you held an asset affects your rate.

2. Account or Wrapper Type

Tax-advantaged wrappers can legally eliminate or defer CGT entirely:

• France's PEA (Plan d'Épargne en Actions) exempts gains after five years.
• Sweden's ISK replaces CGT with a small annual fee on total account value.
• The UK's ISA shelters gains and income completely.
• Spain has Planes de Pensiones (pension plans) where gains are deferred until withdrawal, then taxed as income.

If you are not using the wrapper available in your country, you may be paying tax you do not have to.

3. Asset Class

Crypto, real estate, derivatives, and unlisted shares are frequently taxed differently from listed equities. In several countries, crypto gains were treated as miscellaneous income at full marginal rates before specific crypto tax regimes were introduced. Accumulating vs distributing ETFs also have meaningfully different tax profiles — accumulating funds reinvest dividends internally, which can defer (or in some countries, create deemed) taxable events.

4. Loss Offsetting Rules

Most countries allow capital losses to offset capital gains in the same tax year. Some (like Spain) allow you to carry losses forward for several years. Others restrict cross-asset offsetting — for example, you may not be able to use a crypto loss to offset a stock gain. Knowing your jurisdiction's rules lets you time disposals strategically (within legal limits).

Why Accurate Records Are Non-Negotiable

Here is a concrete example of why cost basis tracking matters.

Suppose you bought 100 shares of a European ETF in three tranches:

• January 2022: 40 shares at €80 = €3,200
• June 2022: 30 shares at €65 = €1,950
• March 2023: 30 shares at €90 = €2,700

In September 2026 you sell 50 shares at €110 each = €5,500 proceeds.

Under FIFO, the first 50 shares sold are the January and June lots (40 + 10):

• Cost basis: (40 × €80) + (10 × €65) = €3,200 + €650 = €3,850
• Taxable gain: €5,500 − €3,850 = €1,650

If you mistakenly used the March lot price (€90) for all 50 shares:

• Incorrect cost basis: 50 × €90 = €4,500
• Understated gain: €1,000 — which could mean an incorrect filing.

Accurate FIFO tracking is not optional; it is what tax authorities expect. This is also where good investment record-keeping pays for itself.

What to Watch Out For: Situations Where This Gets Complicated

• Multi-currency portfolios: If you bought a US stock in USD and your base currency is EUR, your gain (or loss) includes the currency movement — not just the price movement. See multi-currency portfolio tracking for how to handle this.
• Corporate actions: Stock splits, mergers, and spin-offs can reset or adjust your cost basis. Most investors do not track these correctly. Here is why that matters.
• Moving countries: If you change tax residency, some countries impose an exit tax on unrealised gains at the point of departure. This is a significant and often overlooked risk for internationally mobile investors.
• Dividend reinvestment: Automatically reinvested dividends create new cost basis lots. If you do not record them, you will overstate gains later.
• Phantom income (accumulating funds): Some jurisdictions (Germany, for instance) tax a deemed distribution from accumulating funds annually even if you received no cash. Ignoring this creates a double-taxation problem when you eventually sell.

Tracking Everything in One Place

Understanding the tax rules is step one. Step two is having the data to apply them correctly. That means knowing your exact purchase dates, prices, currency rates at acquisition, and every corporate action that affected your holdings — across every account and broker you use.

If you track multiple brokerage accounts or hold assets across asset classes, the record-keeping burden compounds quickly. A portfolio tracker that maintains a full transaction history per asset — including FIFO cost basis — removes the manual spreadsheet work and reduces the risk of filing errors.

WealthFlow tracks your positions across stocks, ETFs, funds (by ISIN/NAV), crypto, pension plans, and real estate — all entered manually, with no broker credentials required. Your data stays yours. When tax season arrives, the FIFO tax-report CSV (available on the Pro plan at €9.99/month + VAT) gives you a ready-to-review breakdown of realised gains per asset, calculated automatically from your transaction history.

You still need a tax professional to file correctly — but you will walk in with the numbers already done.
