Crypto Tax Belgium 2025/2026: Private, Diverse or Professional?
Belgian crypto taxation changed on 1 January 2026. This guide therefore separates the 2025 income year (assessment year 2026) from disposals made from 2026 onward. It also explains how CoinTaxReporting turns exchange and wallet data into a working paper without pretending that every crypto gain is taxed at the same rate.

|---|---|---|
| Income year 2025 (assessment year 2026) | Legacy three-way classification: normal private wealth management, diverse income or professional income | Produces the Belgian 2025 working paper and the relevant Part 2 reconciliation codes |
| Disposals from 1 January 2026 | New Belgian capital-gains tax on financial assets, including crypto, generally at 10% for the standard private-investor regime | Must be evaluated under the 2026 rules and must not be mixed into a 2025 return |
The official Belgian guidance confirms that crypto-assets fall within the new financial-assets regime for sales from 2026. It also confirms a €10,000 annual exemption for assessment year 2027 and special acquisition-value rules for assets held before 2026. See the FPS Finance capital-gains guidance.
Income year 2025: three possible classifications
It is incorrect to say that every Belgian crypto gain in 2025 is automatically taxed at 30%. The Belgian Ruling Commission explicitly distinguishes three possible outcomes:
- Normal management of private wealth: the gain is treated as exempt private income. There is no automatic crypto form code merely because a disposal occurred.
- Diverse income: an occasional or speculative result outside normal private wealth management can fall in the diverse-income section. The statutory special rate is commonly described as 33%, before any applicable municipal surcharge—not 30%.
- Professional income: where the activity is genuinely occupational or business-like, the result belongs in the professional-income framework and requires complete business accounting.
The classification is factual. Frequency is relevant, but it is not a standalone switch. The authority also asks about the source and proportion of invested assets, holding period, borrowing, automation, technical knowledge, occupation, mining activity and the way the portfolio is managed. The official crypto questionnaire is the best checklist for documenting that decision.
Which Belgian return codes are relevant for 2025?
The 2026 personal-income-tax return covers income received in 2025. The CoinTaxReporting Belgium report is a working paper for the official return, not an official return itself.
| Report classification | Official return reference | Meaning |
|---|---|---|
| Private wealth management | No automatic code | Documentation of disposals; no automatic transfer as taxable income |
| Diverse—gains on movable property/securities | 1440-15 / 2440-82; related costs 1441-14 / 2441-81 | Use only after the factual classification has been confirmed |
| Other occasional/speculative income | 1200-61 / 2200-31; related costs 1201-60 / 2201-30 | Potentially relevant for other fact patterns, including certain derivative results |
| Professional activity | 1600-49 / 2600-19; other professional expenses 1606-43 / 2606-13 | Bookkeeping reconciliation only; the complete professional return remains necessary |
These references come from the official preparatory return, Part 2, assessment year 2026. Code 1202/2202 concerns qualifying unclaimed losses from the preceding five years; it is not a generic current-year loss field.
Staking, mining, airdrops, lending and DeFi
These receipts are not automatically “diverse income at 30%”. Their legal nature and the surrounding activity matter. Interest-like or dividend-like income, a speculative one-off receipt and income earned in a professional activity can lead to different sections of the return. Ambiguous staking, mining, reward and airdrop events should therefore remain in a review worksheet until their factual classification is confirmed. The Ruling Commission’s 2026 adapted crypto request expressly added a question about the classification of passive crypto income. The separate guide to Belgian staking and DeFi taxation explains the required evidence.
Crypto swaps, derivatives and cost basis
- A sale or crypto-to-crypto conversion is a disposal that must be recorded. Its tax result still depends on the applicable period and classification.
- Futures and perpetuals are not automatically tax-free. For the 2025 report, unresolved derivative classification remains a review item; from 2026, the official financial-assets guidance expressly includes derivatives.
- FIFO is not presented as a Belgian statutory requirement. It is a documented lot-ordering method used by the report to make the calculation reproducible.
- Transfers between your own wallets are not disposals and must not create artificial proceeds or a new acquisition cost.
What changed for private investors from 2026?
For disposals from 1 January 2026, the official standard private-investor framework generally applies a 10% capital-gains tax to financial assets including crypto. The first €10,000 of realised gains is exempt for assessment year 2027. For assets acquired before 2026, the 31 December 2025 value is central to the opening basis, while a higher provable historical acquisition value can protect against taxing pre-2026 gains. Historical losses cannot be turned into a deductible post-2025 loss. Transaction costs and taxes are not deductible in the statutory gain formula.
This new regime must not be applied retroactively to the 2025 Belgium report. Nor should a 2025 report silently apply the €10,000 exemption: the taxpayer handles personal exemptions and the complete return. See the dedicated Belgium crypto-loss guide before carrying assumptions from the old classification system into the new regime.
Deadlines for the 2026 return
There is no universal 31 May deadline. FPS Finance lists 30 June 2026 for paper returns, 19 July 2026 for ordinary Tax-on-web filing and 16 October 2026 for online returns with specified income. Always check the current official filing page for your situation.
DAC8/CARF: reporting is not the tax calculation
Belgium transposed DAC8/CARF through the law of 16 March 2026. Reporting crypto-asset service providers must perform due diligence, collect prescribed user data and report it to FPS Finance. This does not mean that every exchange reports every transaction immediately, and it does not decide whether a specific receipt is private, diverse or professional income. See the official FPS Finance DAC8/CARF page and our practical Belgium CARF checklist.
How the Belgium tax report helps
CoinTaxReporting separates spot disposals, income-like events, derivatives, funding and unresolved items. For income year 2025 it offers three factual profiles—private, diverse and professional—and reconciles confirmed amounts to the official return references. It does not calculate the taxpayer’s final Belgian tax bill, apply personal allowances or replace the full return and supporting accounts.
FAQ: Belgian Crypto Taxes 2026
Was every Belgian crypto gain taxed at 30% in 2025?
No. Under the pre-2026 framework, normal private wealth management, diverse income and professional income were distinct outcomes. A fixed holding period or trade count did not decide the classification by itself.
Is a crypto-to-crypto trade ignored because no euros were received?
No. It is still a disposal or conversion that must be valued and documented. Whether it creates taxable income depends on the relevant year and tax classification.
Does the 10% regime apply to 2025 disposals?
No. The new standard private-investor regime applies to disposals from 1 January 2026 and must not be applied retroactively to the 2025 working paper.
Is the €10,000 exemption applied per exchange?
No. It is a personal annual exemption for the relevant regime, not a separate allowance for each token, wallet or exchange.
Are Belgian staking rewards always taxed at a fixed rate?
No. The legal nature of the receipt and whether the activity is private, diverse or professional must be determined from the facts.
Does DAC8 calculate the tax due?
No. DAC8 is a reporting and information-exchange framework. It does not decide the substantive classification or calculate the Belgian return.
Can the PDF be filed as the Belgian tax return?
No. It is a traceable working paper. The taxpayer or adviser must confirm the factual profile, complete the official return and consider all non-crypto income, deductions and personal circumstances.
