Section 2 -- Classification Rules

2.1 The Three-Tier System (Income Year 2025)

Belgium applies a facts-and-circumstances classification to determine how crypto gains are taxed. There is no statutory bright-line test. The three tiers are:

Three-Tier System table (Art. 90, al. 1, 1° WIB 92; Art. 171, 1° WIB 92; Art. 23 §1 WIB 92)

Tier	Dutch	French	Tax Rate	Legal Basis
1. Normal management of private patrimony	Normaal beheer van privévermogen / goede huisvader	Gestion normale du patrimoine privé / bon père de famille	TAX FREE	Art. 90, al. 1, 1° WIB 92 (exclusion)
2. Speculative gains	Speculatieve meerwaarden	Plus-values spéculatives	33% + municipal surcharge (avg. 7–8%)	Art. 90, al. 1, 1° and Art. 171, 1° WIB 92
3. Professional income	Beroepsinkomen	Revenus professionnels	25%–50% progressive + social security	Art. 23 §1 WIB 92

2.2 Classification Factors (SDA Ruling Practice)

The Dienst Voorafgaande Beslissingen (DVB/SDA) uses a detailed questionnaire to classify crypto investors. Key factors:

Classification Factors table

Factor	Normal Management (Tax-Free)	Speculative (33%)	Professional (25–50%)
Crypto as % of movable wealth	< 25% (SDA informal threshold)	> 25%	High and systematic
Transaction frequency	Low; buy-and-hold	High volume trading	Very high; daily trading
Holding period	Long (months to years)	Short (days to weeks)	Very short; day trading
Strategy	Passive; long-term appreciation	Active trading; momentum	Full-time activity
Leverage / borrowing	None	May use	Regular use
Automation / bots	None	Possible	Systematic use
Professional knowledge/background	No finance background	Some expertise	Finance/IT professional
Mining activity	None	Minor	Regular commercial mining
Forum/community participation	Minimal	Active	Influencer/educator
Third-party management	None	None	Manages for others
Income dependency	Has separate primary income	Has other income	Crypto is primary income

2.3 The 25% Wealth Threshold

• 25% wealth threshold rule — The SDA applies an informal but consistently enforced threshold: if more than 25% of a taxpayer's movable wealth is invested in cryptocurrency, the SDA quasi-automatically classifies the management as "abnormal" (speculative). This threshold is controversial but well-documented in published rulings.
• Critical note on tracking percentage — The percentage must be tracked from the date of first investment through each year-end. The SDA questionnaire requires a table showing this percentage at each key date.

2.4 Advance Rulings (DVB/SDA)

Advance Rulings table

Aspect	Detail

Section 3 -- Rate Tables

3.1 Tax Rates by Classification (Income Year 2025)

Tax Rates by Classification table (Art. 130–145 WIB 92; Art. 171 WIB 92; FOD Financiën "Belastingtarieven — Inkomstenjaar 2025 (Aanslagjaar 2026)")

Classification	Federal Rate	Municipal Surcharge	Effective Rate	Social Security
Normal management	0%	N/A	0%	No
Speculative (miscellaneous income)	33%	~7–8% of federal tax	~35.4–35.6%	No

Professional income bracket 3	45% on €28,800–€49,840	~7–8%	~48.2–48.6%	Yes
Professional income bracket 4	50% on €49,840+	~7–8%	~53.5–54.0%	Yes

• Personal tax allowance (belastingvrije som) — EUR 10,910 EUR (income year 2025) (Art. 130–145 WIB 92; Art. 171 WIB 92; FOD Financiën "Belastingtarieven — Inkomstenjaar 2025 (Aanslagjaar 2026)")

3.2 Staking / Passive Income Classification

• SDA staking classification rule — The SDA has classified staking rewards as roerend inkomen (movable income / income from movable property) under Art. 17 §1 WIB 92, analogous to interest under Art. 19, 1° WIB 92. (SDA ruling March 2025; Art. 17, 19, 261–269 WIB 92)

Staking / Passive Income table (SDA ruling March 2025; Art. 17, 19, 261–269 WIB 92)

Income Type	Rate	Withholding
Staking rewards (interest analogy)	30% (précompte mobilier / roerende voorheffing)	Self-assessed if no Belgian intermediary

3.3 Upcoming 2026 Regime (Important Context for 2025 Planning)

From 1 January 2026, a new capital gains tax applies:

2026 Regime table (Programme law (Programmawet) 2025; Art. 90, al. 1, 9°, c) WIB 92 (new))

Aspect	Detail
Rate on "normal management" gains	10% (replaces tax-free treatment)
Annual exemption	EUR 10,000 per taxpayer
Historical gains exempt	Gains accrued up to 31 December 2025 are exempt if documented
Speculative gains	Still taxed at 33%
Professional gains	Still taxed at progressive rates
Carry-forward of unused exemption	Up to EUR 1,000/year for max 5 years

Section 4 -- Cost Basis Methods

4.1 Accepted Methods

Belgium does not prescribe a specific cost basis method for crypto. In practice:

Accepted Methods table

Method	Status
FIFO (First In, First Out)	Accepted; most commonly used
Average cost	Accepted
LIFO (Last In, First Out)	Not standard; may be challenged
Specific identification	Accepted if well documented

4.2 Cost Basis Components

• Acquisition cost (aanschaffingswaarde) components — Purchase price in EUR at the date of acquisition; Exchange fees and commissions; Network/gas fees directly attributable to the purchase; Bank transfer fees for deposits to exchanges

4.3 No Expense Deduction for Speculative Income

• No expense deduction for speculative income — Critical rule: For gains taxed as miscellaneous income (33%), no deduction is permitted for expenses — only the acquisition cost can offset the sale proceeds. (Art. 97 WIB 92)

For professional income, normal business expense deductions apply.

Section 5 -- DeFi, Staking, Mining, and Airdrop Treatment

5.1 Mining

Mining table

Scale	Classification	Tax Treatment
Occasional/small scale	Likely miscellaneous income (speculative)	33% + municipal surcharge
Regular/commercial	Professional income	Progressive rates 25%–50% + social security

The SDA and OATR (Opsporingsdienst) tend to quickly classify mining as professional activity due to its regular, organised nature.

5.2 Staking

Staking table

Aspect	Treatment
SDA classification (March 2025 ruling)	Movable income (roerend inkomen) — interest analogy
Tax rate	30% (roerende voorheffing rate)
Tax point	When rewards are received/accessible
Reporting	Separate obligation from capital gains; Part 2 of tax return (roerende inkomsten)
Cost basis for future sale	FMV at receipt date

5.3 DeFi Lending

DeFi Lending table

Activity	Treatment
Depositing crypto into lending protocol	Uncertain — may constitute a disposal or may be treated as a loan
Interest received	Likely movable income at 30% (interest analogy)
Withdrawing from lending protocol	Uncertain

Warning: There is no specific Belgian guidance on DeFi lending. The SDA has not published rulings on LP positions, yield farming, or DeFi protocols. Conservative approach: treat deposits as disposals.

5.4 Liquidity Providing

• Liquidity Providing conservative treatment — No specific guidance. Conservative treatment: Deposit into LP = disposal of underlying crypto (capital gain/loss triggered); LP tokens = new acquisition at FMV; Withdrawal from LP = disposal of LP tokens

5.5 Airdrops

Airdrops table

Type	Treatment
Gratuitous airdrop	Cost basis EUR 0; taxable event at disposal only
Airdrop for service/action	Income at FMV when received; classification depends on overall investor profile

5.6 Hard Forks

• Hard Forks conservative treatment — No specific guidance. Conservative treatment: Cost basis of forked coin = EUR 0; Gain = full proceeds on disposal; Classification follows normal three-tier analysis

Section 6 -- NFT Treatment

6.1 General NFT Classification

Belgium applies the same three-tier classification to NFTs as to other crypto assets:

General NFT Classification table

Scenario	Likely Classification
Buy and hold NFT art long-term	Normal management (tax-free in 2025)
Frequent NFT trading (flipping)	Speculative (33%)
NFT creation and sale as regular activity	Professional income (25–50%)

6.2 NFT-Specific Considerations

NFT-Specific Considerations table

Aspect	Treatment
NFT purchased with crypto	Two transactions: disposal of crypto + acquisition of NFT
NFT sold for crypto	Disposal of NFT + acquisition of crypto
NFT creation (artist)	If regular → professional income
NFT royalties	Likely movable income or professional income depending on regularity

6.3 TOB (Tax on Stock Exchange Transactions)

• TOB does not apply to crypto/NFTs — The Taks op de Beursverrichtingen (TOB) / Taxe sur les Opérations de Bourse does NOT apply to cryptocurrency or NFT transactions. The TOB is limited to transactions in financial instruments executed through a Belgian intermediary on a regulated market. (Art. 120–123 of the Code of Miscellaneous Taxes and Duties (Wetboek Diverse Rechten en Taksen))

Section 7 -- Reporting Requirements

7.1 Tax Return Filing

Tax Return Filing table

Classification	Where to Report

7.2 Centraal Aanspreekpunt (CAP) — Foreign Account Declaration

CAP table

Requirement	Detail
What must be declared	Foreign crypto exchange accounts (Binance, Coinbase, Kraken, etc.)
To whom	National Bank of Belgium — Centraal Aanspreekpunt (CAP)
Deadline	Before filing the tax return
Penalty for non-declaration	Fines and potential criminal prosecution
Belgian exchanges	Not required (domestic accounts)

7.3 Filing Deadlines (Income Year 2025)

Filing Deadlines table

Method	Deadline
Paper filing	Late June 2026 (exact date published annually)
Tax-on-web (e-filing)	Mid-July 2026 (exact date published annually)
Via tax advisor (mandataris)	Late October 2026

7.4 Record-Keeping

Record-Keeping table

Requirement	Detail
Retention period	7 years from the assessment year
Records to maintain	Full transaction logs, cost basis calculations, portfolio value at each year-end, documentation of crypto-to-movable-wealth ratio
SDA ruling documentation	Keep the SDA questionnaire responses and ruling decision indefinitely
Burden of proof	On taxpayer for normal management claim; on administration for professional reclassification

7.5 DAC8 / CARF (From 2026)

• DAC8/CARF reporting — Crypto service providers report Belgian user transaction data to FOD Financiën; Increased audit risk for undeclared crypto gains; Belgian tax authorities have been increasingly auditing crypto holders since 2023

Section 8 -- Loss Offset and Carry-Forward

8.1 Loss Rules by Classification

Loss Rules by Classification table

Classification	Loss Offset	Carry-Forward
Normal management	N/A (gains are tax-free, so losses are irrelevant)	No
Speculative (miscellaneous income)	Losses can only offset gains within the same category (miscellaneous/speculative crypto gains) in the same tax year	No carry-forward
Professional income	Losses deductible as business losses; can offset other professional income	Carry-forward possible under normal business loss rules

8.2 Critical Limitation — Speculative Losses

• Speculative losses ring-fencing — Speculative crypto losses CANNOT offset: Employment income; Rental income; Movable income (dividends, interest); Other types of miscellaneous income not in the same sub-category. This is one of the harshest aspects of Belgian crypto taxation. (Art. 90 and Art. 103 WIB 92)

8.3 2026 Regime — Loss Rules

• 2026 loss rules — Under the new 10% capital gains tax from 2026: Losses are deductible only against gains in the same sub-category of financial assets; Crypto losses cannot offset, e.g., share gains; No carry-forward of losses

Section 9 -- Anti-Avoidance Rules

9.1 General Anti-Abuse Provision

• General anti-abuse provision — Belgium has a general anti-abuse provision that allows the tax administration to recharacterise transactions lacking genuine economic substance. This includes artificial structures designed to avoid crypto taxation. (Art. 344, §1 WIB 92)

9.2 Substance Over Form

• Substance over form analysis — The SDA and courts apply a substance-over-form analysis. Even if a taxpayer formally holds crypto long-term, the overall pattern of behaviour determines classification. Key case law precedents include the Court of Cassation rulings of 1968/1969 defining professional vs private activities.

9.3 Increased Audit Activity

Belgian tax authorities have significantly increased crypto-related audits since 2023. Common triggers: Large bank deposits from crypto exchange withdrawals; Inconsistencies between declared income and lifestyle; Information received from foreign tax authorities; DAC8/CARF reports (from 2026); Undeclared CAP accounts

9.4 Penalties

Penalties table

Offence	Penalty
Late filing	Administrative fines (EUR 50–1,250)
Undeclared crypto income	Tax surcharge of 10%–200% of unpaid tax
Undeclared foreign accounts (CAP)	Separate fines; potential criminal prosecution
Fraud	Criminal penalties; tax surcharge up to 200%

Section 10 -- Worked Examples

Example 1 -- Normal Management (Tax-Free in 2025)

Input: Belgian resident, employed engineer. Bought 2 BTC in January 2023 at EUR 20,000 each. Sold 2 BTC in November 2025 at EUR 55,000 each. Total 3 trades in 3 years. Crypto represents 15% of movable wealth. No leverage, no bots, no mining.

Classification analysis:

Factors:
  - Low frequency: 1 buy + 1 sell in 3 years                → Normal management
  - Long holding period: ~34 months                          → Normal management
  - Crypto < 25% of movable wealth (15%)                    → Normal management
  - No leverage, no automation                               → Normal management
  - Employed separately; crypto not primary income            → Normal management
  - Passive buy-and-hold strategy                            → Normal management

Classification: Normal management of private patrimony

Gain:  2 × (EUR 55,000 - EUR 20,000) = EUR 70,000
Tax:   EUR 0 (tax-free under normal management)

Recommendation: Obtain an SDA ruling to confirm classification, especially given the significant gain amount.

Example 2 -- Speculative Gains (33%)

Input: Belgian resident. Made 150+ trades in 2025 across 4 exchanges. Mix of short-term and medium-term positions. Crypto represents 40% of movable wealth. Net gain of EUR 25,000 after costs. No leverage but uses portfolio tracking tools actively.

Classification analysis:

Factors:
  - High frequency: 150+ trades                             → Speculative
  - Crypto > 25% threshold (40%)                            → Speculative (SDA quasi-automatic)
  - Mix of holding periods                                   → Speculative
  - Active management with tools                             → Speculative
  - Not full-time; has other employment                      → Not professional

Classification: Speculative — miscellaneous income (Art. 90, 1° WIB 92)

Gain:           EUR 25,000
Federal tax:    EUR 25,000 × 33% = EUR 8,250
Municipal surcharge (assume 7.5%): EUR 8,250 × 7.5% = EUR 618.75
Total tax:      EUR 8,868.75

Reporting: Part 2, Section XV — Diverse inkomsten (Code 1440)

Example 3 -- Professional Income

Input: Belgian resident, no other employment. Full-time crypto trader. 1,000+ trades in 2025. Uses leverage and automated bots. Manages a small fund for friends. Net income EUR 80,000.

Classification analysis:

Factors:
  - Very high frequency: 1,000+ trades                      → Professional
  - Full-time activity; primary income source                → Professional
  - Leverage and automation                                  → Professional
  - Manages for third parties                                → Professional

Classification: Professional income (Art. 23, §1 WIB 92)

Taxable income: EUR 80,000
Personal allowance: EUR 10,910 (tax-free)
Remaining: EUR 69,090

Tax computation:
  EUR 16,320 × 25%              = EUR 4,080.00
  (EUR 28,800 - EUR 16,320) × 40% = EUR 4,992.00
  (EUR 49,840 - EUR 28,800) × 45% = EUR 9,468.00
  (EUR 69,090 - EUR 49,840) × 50% = EUR 9,625.00
  Subtotal:                        EUR 28,165.00
  Less personal allowance credit:  EUR 10,910 × 25% = EUR -2,727.50
  Federal tax:                     EUR 25,437.50
  Municipal surcharge (7.5%):      EUR 1,907.81
  Total income tax:                EUR 27,345.31
  Social security (~20.5%):        EUR 80,000 × 20.5% = EUR 16,400.00
  TOTAL TAX BURDEN:                EUR 43,745.31 (~54.7%)

Reporting: Part 1 — Beroepsinkomsten / Revenus professionnels

Self-Checks

Before finalising any Belgium crypto computation, verify:

• Three-tier classification analysis completed with documented factors
• Crypto-to-movable-wealth ratio calculated (25% threshold)
• All amounts in EUR at transaction date exchange rates
• Cost basis method consistently applied (FIFO or average — document choice)
• Speculative losses NOT offset against other income types
• Staking rewards reported separately as movable income (30%)
• Foreign exchange accounts declared to CAP (National Bank)
• Municipal surcharge added to federal tax
• Social security calculated for professional classification
• Record of SDA ruling (if obtained) retained
• Planning for 2026 regime change considered (10% tax on normal management gains)

PROHIBITIONS

• NEVER assume all crypto gains are tax-free in Belgium — only "normal management" gains are exempt (and only for 2025; 10% from 2026)
• NEVER rely solely on holding period to determine classification — the SDA considers multiple factors holistically
• NEVER ignore the 25% movable wealth threshold — it is the most heavily weighted factor in SDA practice
• NEVER offset speculative crypto losses against employment or other income — they are ring-fenced
• NEVER forget to declare foreign exchange accounts to the CAP (National Bank)
• NEVER treat mining as normal management — the SDA/OATR considers mining inherently professional or speculative
• NEVER ignore municipal surcharges when computing tax — they add ~7–8% to the federal rate
• NEVER present a single ruling as universally applicable — each SDA ruling is specific to the taxpayer's facts
• NEVER compute gains without verified cost basis records
• NEVER present crypto tax positions as definitive — always label as estimated and flag for professional review
