A simple guide for declaring crypto in Belgium based on your investor type. Includes MyMinFin steps and SPF-compliant fields.

Filing your crypto taxes in Belgium can feel confusing, especially if you’re unsure where to begin or which category you fall under. With different rules for casual holders, active traders, and full-time crypto professionals, knowing how to declare correctly is key.

The good news is that once you understand your investor type, the actual filing process becomes much simpler. Whether you’re a long-term investor with passive income or someone actively trading for profit, this guide will walk you through every step. 

We’ll explain what the Belgian tax office expects, which forms you need to fill out, and how to make sure you’re fully compliant.

Understanding the Three Crypto Investor Types in Belgium

Before you declare any crypto taxes in Belgium, it’s important to know how the Belgian tax authority (SPF) might classify you. Your investor category affects how your profits are taxed, what forms you need to complete, and how your income is reported. Let’s understand all the categories:

Who Is a Prudent Manager?

A prudent manager (Bon Père De Famille) is someone who invests in crypto casually and with a long-term mindset. This investor typically avoids high-risk moves and trades infrequently. The approach focuses more on preserving wealth than chasing profits. The SPF often considers this group exempt from capital gains tax on crypto, unless there is significant passive income.

To be seen as a prudent manager, your crypto activity must follow the “goede huisvader” principle, meaning you act as a responsible investor. Holding for the long term, investing a small portion of your total assets, and avoiding speculative strategies help reinforce your status in this category.

Who Is a Speculative Investor?

A speculative investor (Spéculateur) trades more frequently and often aims for short-term profits. This group includes users who buy and sell crypto regularly, engage with derivatives, or allocate a large share of their wealth to digital assets. The SPF considers gains made by speculative investors as miscellaneous income, subject to 33% tax.

What sets them apart is the volume and nature of their activity. Using automated tools, reacting quickly to market trends, and taking high risks are all traits that shift someone from “prudent” to “speculative.” The more active you are, the more likely you’ll be taxed under this category.

Who Is a Professional Trader?

A professional trader (Professionnel) operates like a business. This category includes those who mine crypto, trade full-time, or earn the majority of their income from digital assets. Their income is taxed progressively, just like regular business income, with rates between 25% and 50% based on total annual earnings.

SPF will look at whether you use advanced tools, have a structured workflow, or invest for others. Even your equipment, such as mining rigs or professional trading platforms, could support this classification. If your crypto work resembles a professional enterprise, you’ll fall under this bracket and must declare accordingly.

How to Declare Crypto On Taxes as a Prudent Manager?

If you’re a prudent manager, you may not owe tax on capital gains. However, passive income like interest from lending must still be reported. Here’s how to declare it properly on your Belgian tax return.

Access the MyMinFin Platform

Start by logging into the MyMinFin platform, the official portal for tax declarations in Belgium. You can use your eID or Itsme app to access your account securely. This is the starting point for all individual crypto declarations.

Once inside, locate your annual tax return and begin filling out the relevant sections based on your income. For prudent managers, you’ll only need to proceed if you’ve earned passive income such as interest or staking rewards that qualify under movable property income.

Navigate to Deel 1, Vak VII

If you’ve earned passive income from crypto, go to Deel 1 of your return. Within this section, find Vak VII, which is used to report “Inkomsten van kapitalen en roerende goederen” (income from capital and movable property). This applies specifically to interest-like earnings.

Make sure you’re not reporting any capital gains here, as those are generally not taxable for prudent managers. This section is strictly for passive income such as interest from crypto lending platforms or rewards that mimic fixed income returns.

Enter Passive Income in Field 1444

Inside Vak VII, locate subsection b) for “Andere inkomsten zonder roerende voorheffing.” Then find field 1444 that reports income taxable at the standard 30% rate. This is where you declare any passive crypto income you’ve earned.

Be sure to convert the value of your earnings into euros at the time you receive them. Supporting records such as lending statements or wallet screenshots can help justify your entry if requested by the SPF.

How to Declare Crypto On Taxes as a Speculative Investor?

Speculative investors must report both capital gains and passive income. If you’ve traded frequently or aimed for short-term profits, you’ll likely fall into this category. Here’s how to declare your earnings on MyMinFin.

Report Passive Income

Start by reporting any interest earned from lending platforms or similar passive income sources. Navigate to Deel 1 of your tax return and open Vak VII, which is designated for “Inkomsten van kapitalen en roerende goederen.”

Inside this section, look for subsection b) and locate field 1444. This is where you’ll report passive income that’s taxed at 30%. Be sure to calculate the euro value at the time the income was received and have supporting records ready.

Report Capital Gains in Deel 2, Vak XV

Your next step is to report your crypto trading profits. Go to Deel 2, then find Vak XV, which is used for declaring “Diverse inkomsten” or miscellaneous income. This is where speculative capital gains are reported.

Enter the total value of your gains in field 1440 (brutobedrag). If you used crypto tax software, it should have already deducted any trading fees from the total gain. If not, make sure you calculate your net profit manually using valid documentation.

Deduct Past Capital Losses (if applicable)

If you’ve had losses in previous years, you may be able to offset them against current gains. Navigate to field 1202 in the same Deel 1, under “c) nog niet afgetrokken verliezen van de vorige 5 jaren.”

This field allows you to deduct losses carried forward from the last five years, helping reduce your current tax liability. You must retain proof of these past losses, such as exchange logs or tax reports, for validation by the SPF if requested.

How to Declare Crypto On Taxes as a Professional Trader?

Professional traders must report all income and expenses like a business. If crypto is your main income source, through trading, mining, or services, follow these steps to file your taxes properly in Belgium.

Access Deel 2, Vak XIV for Business Details

Start by logging into MyMinFin and go to Deel 2, where business-related details are recorded. In Vak XIV, provide your beroep en ondernemingsnummer (profession and company number), which identifies you as a professional.

This section establishes that your crypto activities are conducted as a business, not a hobby. Make sure all the information is accurate and up to date, especially if your income from crypto spans multiple operations or services.

Declare Trading Gains in Vak XVII

Next, move to Vak XVII, which is designated for “Winst uit nijverheids-, handels-, of landbouwondernemingen.” This is where you’ll declare all your trading income or mining profits as business earnings.

Use field 1600 to report your gross profit, labelled as Brutowinst van de eigenlijke exploitatie. This amount should include all income earned before deducting expenses. Be sure to account for everything, from crypto sales to staking rewards treated as business income.

Declare Social Contributions and Expenses

Social contributions and business costs are declared separately. Use field 1632 to report any social security payments you’ve made as part of your professional crypto activity.

Then use field 1606 to declare allowable professional expenses such as mining hardware, electricity, software subscriptions, or trading tools. These deductions can significantly reduce your taxable base, so it’s important to keep all receipts and related documentation.

Report Past Losses in Deel 1, Vak VIII

If your crypto business made losses in earlier years, you may still be able to claim them. Go to Deel 1, then Vak VIII, which deals with “Aftrekbare Vorige Verliezen en Bestedingen.”

Use field 1349 to report any undeducted business losses from previous tax years. These can help lower your overall tax burden if documented correctly. Always retain detailed records to justify the deductions in case of a future audit.

How To Classify Your Tax Reporting Status In Belgium?

If you’re unsure whether you’re a prudent manager, speculative investor, or professional trader, the Belgian tax office has provided a 17-question framework to help guide your classification. Your answers determine not just how much tax you owe, but how and where to report your crypto activity.

This framework helps the SPF understand the nature of your trading behaviour, your income goals, and your level of expertise. Answering these questions honestly can prevent misclassification and reduce audit risk.

  • How did you acquire your cryptocurrencies?? (Savings, inheritance, donation, or asset conversion?)
  • How many years have you been investing in crypto?
  • How frequently do you buy and sell cryptocurrencies per year?
  • How long have the crypto assets you wish to transfer or dispose of been held?
  • What is your investment strategy? (Buy & hold, trend trading, active trading, arbitrage?)
  • Do you mine crypto? (Using your own rig or a pool? Provide details.)
  • Do you use automated trading tools or software?
  • Did you build the software yourself? (If yes, give more information.)
  • What is your current job and education level?
  • Have you gained crypto-related knowledge through your work?
  • Have you invested in a cryptocurrency investment fund?
  • Are you active in the crypto community (forums, blogs, or speaking)?
  • What portion of your total assets is invested in crypto?
  • Do you also invest in other assets like stocks, bonds, or gold? (Give a breakdown.)
  • Do you use special equipment like hardware wallets for crypto security?
  • Do you invest in crypto for others? (Who and how much?)
  • Have you borrowed money to buy crypto? (Amount and lender details?)

Reviewing your answers to these questions will guide you toward the correct investor category. If you’re still uncertain, consult a tax advisor or use software like KoinX, which can analyse your activity to help classify you correctly.

Frequently Asked Questions

What Happens If I Choose the Wrong Investor Type?

Choosing the wrong category, like declaring as a prudent manager when you’re actually a speculative investor, can lead to incorrect tax filings. If the SPF reviews your case and finds mismatches, you may face penalties or reassessment. It’s best to review your trading behaviour thoroughly or use a crypto tax tool like KoinX to guide you towards the correct investor classification.

Can I Change My Investor Status in the Future?

Yes, your classification can change over time based on how you interact with crypto. For example, if you move from occasional investing to frequent trading, you may shift from a prudent manager to a speculative investor. It’s important to reassess your status each year and adjust your tax filings accordingly to stay compliant with Belgian tax rules.

Is Crypto Received as a Gift or Donation Taxable in Belgium?

Yes, crypto received as a gift or donation is subject to gift tax in Belgium. The rate depends on your relationship to the giver and the region you live in. The tax is calculated based on the market value of the crypto at the time of the transfer. It’s important to declare these gifts separately from regular capital gains or income.

Do I Need to Report Tokens Held in DeFi Wallets?

Yes, tokens held in DeFi wallets should be reported if they generate income or are later sold for a gain. Even though these wallets are decentralised, the SPF expects accurate reporting of all transactions. Keep track of the wallet addresses, transaction timestamps, and the euro value at the time of each activity for accurate declaration.

How Long Should I Keep My Crypto Records for SPF?

Belgian tax authorities can audit your returns for up to 3 years in normal cases, and up to 10 years in cases of suspected fraud. To stay safe, it’s recommended to keep all your crypto records, including transaction logs, wallet addresses, and tax reports, for at least 10 years. This ensures you’re fully prepared if the SPF requests documentation later.
