You have decided to start investing. What are the concrete steps to buy your first stocks or ETF in Belgium? This is a walkthrough, not advice.

Step 1 — Fundamentals first

Before you open an account, check:

  • [ ] No debts with >5% interest (credit card, personal loan). Pay these off first.
  • [ ] Emergency fund of 3-6 months of fixed expenses on a savings account. See Building an emergency fund.
  • [ ] Employer match in EIP/group insurance fully used.
  • [ ] Pension savings set up and funded (€1,050 or €1,350). See Pension savings 1050 or 1350(NL).

Only then start investing.

Step 2 — Choose a broker

For most Belgian beginners:

  • Full tax handling done for you: Bolero, Keytrade, or MeDirect (Belgian brokers).
  • Low costs + willing to do some tax work yourself: DEGIRO or Saxo.
  • Maximum cost efficiency: Trade Republic or Interactive Brokers (full admin on you).

See the complete comparison in Bolero vs Keytrade vs DEGIRO(NL) and the pillar article Investing in Belgium(NL).

Step 3 — Open an account

At a Belgian broker (Bolero, Keytrade, MeDirect):

  1. Online application via the website.
  2. itsme® for digital identification.
  3. Complete the MiFID II questionnaire (knowledge test).
  4. Declaration of tax residency (Belgium).
  5. Wait for activation (typically 1-3 business days).

At a foreign broker (DEGIRO/Saxo/IBKR):

  1. Online registration.
  2. Upload ID proof.
  3. Declaration to NBB CAP for your first tax return. See Filing the NBB declaration(NL).

Step 4 — Deposit funds

First deposit via bank transfer from your regular bank account to the broker. The deposit typically appears within 1-2 business days on your securities account as “cash available”.

💡 Tip for beginners: do not immediately deposit your entire available amount. Deposit a portion first (e.g. 25%), make a first purchase, learn how the system works. Only then add the rest.

Step 5 — What to buy?

For a first purchase, a single world index ETF is usually the most sensible choice:

  • VWCE (Vanguard FTSE All-World) — developed + emerging markets in one fund, registered in Belgium → 1.32% TOB.
  • IWDA (iShares Core MSCI World) — developed markets, not registered in Belgium → 0.12% TOB.

For the choice between the two: see IWDA vs VWCE(NL).

Step 6 — The purchase itself

In your broker platform:

  1. Search for the ETF via ISIN (not via ticker — for certainty):
    – VWCE: IE00BK5BQT80
    – IWDA: IE00B4L5Y983
  2. Choose the trading venue (typically Xetra or Euronext Amsterdam for IWDA/VWCE).
  3. Specify:
    – Number of shares (no fractional trading on most Belgian brokers — must be whole shares).
    – Limit order or market order. For ETFs: a market order suffices during normal trading hours.
  4. Confirm and place the order.

The broker automatically calculates:
– TOB (depending on the type of ETF).
– Transaction fees (typically €5-15 or <€2 at DEGIRO).
– Any FX spread (for non-EUR ETFs — VWCE/IWDA are both USD-denominated, even though quoted in EUR).

Step 7 — And then?

Stop looking. Really.

  • Set up a recurring automatic deposit for monthly or quarterly top-ups.
  • Check your portfolio once per quarter, no more often.
  • On big news (a crash, market move): do nothing. Markets recover.
  • On price rises: do not exit to lock in the gain — that is loss aversion. See Behavioural finance(NL).

Common mistakes on a first purchase

Mistake 1 — Choosing the wrong market. VWCE is listed on Xetra, Borsa Italiana, and some other exchanges. Not in Belgium. On your broker platform: pick a market, usually Xetra. Wrong market → possibly higher costs or no volume.

Mistake 2 — Market order outside trading hours. Placing an order at 11pm → execution only at the next market open. Preferably trade during the day within opening hours.

Mistake 3 — Purchase too small. A €100 purchase on Bolero costs €7.50 in transaction fees = 7.5% direct loss. Work with amounts of at least €500 to keep transaction costs in proportion, or pick a low-cost broker (DEGIRO/Trade Republic).

Mistake 4 — Unfamiliar with the tax reporting. At a Belgian broker: little to worry about. At a foreign broker: make sure you understand what you have to declare yourself (TOB at non-handling brokers, dividends, capital gains tax).

A note on the 2026 capital-gains tax

Since 1 January 2026 Belgium applies a 10% capital-gains tax on realised gains on financial assets above an annual exemption of €10.000 (indexed). For most beginners with a single world-index ETF this only matters when you actually sell — accumulating ETFs (VWCE/IWDA) do not trigger this tax merely by holding. See Belgian investment taxes(NL).
