📅 Last updated: 8 May 2026

 ·  🇧🇪 For: Belgian beginners

Before you open your first securities account, work through this checklist. It saves time and prevents you from having to make adjustments later.

Pre-opening checklist

• [ ] No debts >5% interest (credit card, personal loan) — pay off first
• [ ] Emergency fund built — 3-6 months of fixed costs in a savings account
• [ ] Employer EIP fully used — don’t miss the free match
• [ ] Pension savings activated — €1.050 (30% credit) or €1.350 (25% credit) per year; contributions allowed through the calendar year you turn 64
• [ ] Investment goal clear — retirement, child’s studies, wealth growth?
• [ ] Horizon defined — minimum 5+ years for equities
• [ ] Risk profile assessed — can you handle a 30% drawdown emotionally?

What you need for opening

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

1. eID or passport for identification.
2. itsme® (digital confirmation).
3. Belgian bank account number (IBAN) for deposits.
4. National register number for tax reporting.
5. Recent payslip or tax assessment (some brokers ask for this).

With a foreign broker (DEGIRO, Saxo, IBKR, Trade Republic):

1. Same as above.
2. Plus: one-time registration with the NBB CAP via cappcc.nbb.be, plus annual declaration on the tax return (vak XIII Rubriek A, code 1075-89).
3. Plus: for DEGIRO: two separate registrations (securities account + Flatex cash account).

MiFID II questionnaire

Mandatory with every securities account: a short questionnaire about your:
– Knowledge and experience
– Financial situation
– Investment goals
– Risk tolerance

Answer honestly. The broker classifies you as defensive, neutral, dynamic or aggressive — this determines which products you are allowed to buy via this platform.

First deposit

Amount: start small (e.g. €500-1,000) even if you have much more. First learn how the platform works before you deposit large amounts.

Method: SEPA transfer from your bank account to the securities account. Appears within 1-2 business days.

First purchase

For most beginners: a single world index ETF is a sensible first purchase:

• VWCE (registered in Belgium, 1.32% TOB)
• IWDA (not registered in Belgium, 0.12% TOB)

See IWDA vs VWCE (NL) for the choice.

After the first purchase

• [ ] Set up an automatic monthly deposit — discipline > timing
• [ ] Don’t forget: quarterly check, not daily
• [ ] No impulse decisions during market dips
• [ ] Keep documents for the annual tax return

Common mistakes

• ❌ Opening an account without an emergency fund → panic selling at the first dip
• ❌ Too large a first deposit without platform familiarity
• ❌ Not knowing what type of ETF you are buying (accumulating/distributing, registered in BE?)
• ❌ Opening multiple platforms at the same time — overcomplexity

The choice that decides the rest: Belgian-established or not

Everything above is administration. The decision with the longest tail is a different one: do you choose a Belgian-established broker or not? It determines years of work, or the absence of it.

Belgian-established brokers include Bolero, Keytrade, MeDirect and Saxo (through its Belgian branch). DEGIRO, Interactive Brokers and Trade Republic are foreign institutions.

What the CAP declaration involves

Open an account at a foreign institution and you report its existence to the National Bank’s Central Contact Point: name, country and institution. This is done once, by the time you file your tax return, and does not need repeating annually while nothing changes. You also tick the foreign account on the return itself.

Failing to do so risks a fine under art. 445 WIB92/CIR92 — €50 where there is no bad faith.

Before you place the first order

1. Set your tax choices. At a Belgian broker you decide now whether to keep automatic capital-gains withholding. Brokers often apply their own deadline, stricter than the statutory one.
2. Note the tariff tier. Under a tiered tariff, buying less often in larger amounts is cheaper than small monthly purchases.
3. Check the fund, not just the broker. Stock-exchange tax depends on the fund: 0.12% or 1.32% for an accumulating ETF, according to FSMA registration. For monthly investors that gap outweighs the commission.
