An overview per exchange: which crypto accounts must you report to the CAP of the National Bank of Belgium? With per-platform advice, a step-by-step guide and DAC8 context.
A Belgian with crypto on a foreign platform? Then you may have to report your account to the Central Point of Contact (CAP) of the National Bank of Belgium. But not every platform falls under that obligation. In this overview we explain per exchange what you do and do not have to do.
🔍 What is the CAP and why do you have to report?
The Central Point of Contact (CAP) is a register at the National Bank of Belgium where you are required to declare foreign accounts. The legal basis: article 307, §1/1 WIB 92. The aim is to give the tax authority visibility into assets held outside the Belgian banking system.
The reporting obligation applies to accounts at foreign banking, exchange, credit or savings institutions. But this is where the difficulty lies: most crypto platforms are not a bank or credit institution in the legal sense. Even so, FOD Financiën (the Belgian tax authority) recommends erring on the side of caution.
You have to make the report in two places:
- At the CAP - once, via the online form of the National Bank of Belgium (or by post)
- In your tax return - annually in Box XIII, section A ("Foreign accounts")
🏦 Per exchange: do you have to report or not?
Below is an overview of the most popular platforms among Belgian users. The rules may evolve, when in doubt: always report.
| Platform | Country | Legal status | CAP report required? | Notes |
|---|---|---|---|---|
| Bitvavo | Netherlands | Crypto asset service provider (CASP) | Strictly speaking: no | The Belgian Minister of Finance confirmed in 2022 that crypto platforms that are not regarded as a bank do not fall under the reporting obligation. Bitvavo is not a bank. |
| Binance | Variable (Cayman, Malta) | CASP, no banking licence | Strictly speaking: no, but recommended | Binance operates through multiple entities. FOD Financiën recommends reporting foreign crypto accounts in any case. Read our Binance CAP guide for the steps. |
| Coinbase | Ireland (EU entity) | CASP, registered as an e-money institution | Borderline case - recommended | Coinbase Ireland is registered as an e-money institution with the Central Bank of Ireland, which brings it closer to a "financial institution". Safest option: report. |
| Kraken | US / UK entity | CASP | Strictly speaking: no, but recommended | Kraken does not fall under the legal definition, but the tax authority is becoming increasingly strict. Read our Kraken CAP guide. |
| Revolut | Lithuania / Belgium (branch) | Bank (Revolut Bank UAB, Lithuanian banking licence, Belgian branch since 2025) | Depends on your IBAN | Revolut operates in Belgium via Revolut Bank UAB Belgian Branch (Brussels). Since April 2025 new Belgian customers automatically receive a Belgian IBAN (BE...) - in which case the account is not foreign and the CAP obligation lapses. Do you still have a Lithuanian IBAN (LT...)? Then the reporting obligation applies until you have migrated. Check your IBAN in the Revolut app. |
| Trade Republic | Germany | Bank (BaFin licence) | Yes | Trade Republic is a bank with a German banking licence. Foreign bank account = reporting obligation. |
| MetaMask / DeFi wallets | n/a | Self-custodied wallet | No | There is no intermediary or institution. A self-custodied wallet is not an "account at an institution". |
Important: from 1 December 2026, crypto accounts will be explicitly included in the CAP regulations. The borderline cases above then disappear: from that moment foreign crypto exchanges formally fall under the reporting obligation. Anyone who already reports now does not have to do anything extra later.
📝 Step by step: reporting to the CAP via MyMinfin
The report can be made electronically via the CAP form of the National Bank of Belgium:
- Go to nbb.be/nl/centraal-aanspreekpunt
- Log in with your eID or itsme
- Click on "Report an account"
- Fill in: the name of the platform, country of establishment, and the account number (or "crypto wallet" if there is no IBAN)
- Click on "Confirm"
In your tax return you then tick that you hold a foreign account (Box XIII, section A). You do not have to enter the balance, only the existence of the account.
When to report? You must notify the CAP before you file your tax return. Did you forget the report? Do it anyway, better late than never. You can report opening and closing at the same time if the account has since been closed.
🔄 DAC8: what exchanges automatically report since 2026
In addition to the CAP reporting obligation, something fundamental has changed since 1 January 2026: the European DAC8 directive requires crypto platforms to automatically pass on data to the tax authorities of EU member states. The Belgian implementing law was adopted on 12 March 2026 and published in the Belgian Official Gazette on 1 April 2026. The reporting covers:
- Purchase and sale transactions
- Account balances at year-end
- Wallet data and identification
The first "crypto statements" are expected in September 2027, for tax year 2026. Exchanges such as Binance, Coinbase and Kraken must supply this data. Read more in our detailed DAC8 guide.
The consequence: even if you are formally not required to report via the CAP, the tax authority already knows what you hold. Not declaring is therefore becoming increasingly risky.
❓ FAQ: frequently asked questions
Do I have to report my Bitvavo account to the CAP?
Strictly legally not, according to the confirmation of the Minister of Finance in 2022. Bitvavo is not a bank or credit institution. But because of the DAC8 reporting that has been running since 1 January 2026, and because crypto accounts will explicitly fall under the CAP regulations from 1 December 2026, reporting is recommended in any case.
I have a Belgian IBAN at Revolut. Do I still have to report?
No. Since April 2025 Revolut operates in Belgium via a Belgian branch and customers receive a BE IBAN. A Belgian IBAN means that the account is no longer regarded as "foreign" and the CAP reporting obligation lapses. Do you still have an LT IBAN? Then the reporting obligation applies until you have migrated.
What if I forgot?
Report as soon as possible anyway. The penalty for not reporting can add up, but proactively regularising is judged more leniently than when the tax authority discovers it itself via DAC8 data.
Do I have to report my MetaMask or Ledger?
No. Self-custodied wallets do not fall under the CAP reporting obligation, there is no intermediary or institution.
Does DAC8 change the CAP rules?
The CAP rules themselves do not change, but the information symmetry does. The tax authority now automatically receives data from exchanges. CAP reporting and DAC8 reporting are two separate obligations.
