Bitcoin in Corporate Balance Sheets: Accounting and Treasury Strategy
Introduction: The Bitcoin Treasury Strategy
MicroStrategy leads the way: when Bitcoin becomes a strategic corporate treasury asset.
Since MicroStrategy announced in August 2020 the acquisition of 21,454 bitcoins for $250 million, the idea of integrating Bitcoin into corporate treasury has gained legitimacy. By December 2025, Strategy (formerly MicroStrategy) holds over 446,000 BTC, valued at more than $37 billion.
This strategy, once considered eccentric, now attracts the attention of CFOs, accountants, and executives worldwide. In France, a few pioneering companies are exploring this path, but accounting and tax questions remain complex.
This guide is intended for professionals (CFOs, accountants, executives) wishing to understand the implications of holding Bitcoin on a French company's balance sheet.

1. Why Companies Buy Bitcoin
Protection against inflation and diversification: understanding corporate treasury motivations.
1.1 The MicroStrategy/Strategy Approach
Michael Saylor, CEO of MicroStrategy (renamed Strategy in 2024), theorized the approach:
"Cash is a melting position. Inflation erodes 10-15% of the value of cash each year. Bitcoin is monetary energy stored in digital form."
Evolution of Strategy's Holdings:
| Date | BTC Held | Average Cost | Value (Dec. 2025) |
|---|---|---|---|
| Aug 2020 | 21,454 | $11,653 | ~$1.8 Bn |
| Dec 2021 | 124,391 | $30,159 | ~$10.5 Bn |
| Dec 2023 | 189,150 | $31,168 | ~$16 Bn |
| Dec 2025 | 446,400 | ~$40,000 | ~$38 Bn |
1.2 Other Companies with Bitcoin Treasury
| Company | BTC Held | Sector | Country |
|---|---|---|---|
| Strategy | 446,400 | Software/BI | USA |
| Marathon Digital | 44,394 | Mining | USA |
| Riot Platforms | 17,429 | Mining | USA |
| Tesla | 9,720* | Automotive | USA |
| Block (ex-Square) | 8,027 | Fintech | USA |
| Hut 8 | 10,096 | Mining | Canada |
| Coinbase | 9,480 | Exchange | USA |
| Galaxy Digital | 8,100 | Finance | USA |
*Tesla sold 75% of its holdings in 2022
1.3 Motivations
| Motivation | Description | Associated Risk |
|---|---|---|
| Inflation protection | Preserve purchasing power of treasury | BTC volatility |
| Diversification | Not everything in cash/bonds | Concentration risk |
| Technology signal | Show innovative vision | Possible negative perception |
| Financing access | Use BTC as collateral | Margin calls |
| Ideological conviction | Believe in Bitcoin's future | Confirmation bias |
1.4 French Companies Concerned
The phenomenon is still limited in France, but some pioneers exist:
- Crypto sector startups
- Tech companies with long-term vision
- Family holdings
- Companies with excess cash without immediate use
2. French Accounting Framework
Intangible assets and historical cost: decoding accounting treatment under PCG.
2.1 Accounting Classification
In French accounting (PCG - Plan Comptable Général), crypto-assets are generally classified as intangible assets:
"Crypto-assets, in the absence of a specific accounting regime, are recorded according to their nature and the purpose assigned to them by the entity."
Source: ANC, Regulation 2014-03 as amended
2.2 Classification by Use
| Use | Classification | Account |
|---|---|---|
| Long-term holding | Intangible fixed asset | 205 (Concessions, patents...) or 208 (Other) |
| Active trading | Inventory/Current asset | 37 (Merchandise inventory) |
| Treasury | Open debate | 50 or 208 depending on doctrine |
2.3 Valuation Method
On entry:
- Acquisition cost: Purchase price + ancillary costs
At closing:
- Historical cost method: Maintained at purchase cost
- Impairment provision: If market value < purchase cost
⚠️ Warning: Under French standards, unrealized gains are NOT recorded (prudence principle). Only unrealized losses lead to provisions.
2.4 Standard Accounting Entries
Bitcoin Acquisition:
D 208 "Other intangible assets" €100,000
C 512 "Bank" €100,000
(Acquisition of X BTC at rate of €Y/BTC)
Impairment Provision (if decline):
D 6816 "Provision charges" €20,000
C 2908 "Intangible asset provisions" €20,000
(Impairment provision, Dec 31 rate below cost)
Sale with Capital Gain:
D 512 "Bank" €150,000
C 208 "Other intangible assets" €100,000
C 775 "Asset disposal proceeds" €50,000
(Sale of X BTC with €50,000 capital gain)
2.5 Notes to Accounts
The notes to accounts must mention:
- Nature and amount of crypto-assets held
- Valuation method used
- Associated risks
- Any provisions
3. International Comparison
IFRS, US GAAP, PCG: the FASB revolution changes the game for American companies.
3.1 IFRS Standards
IFRS (international standards) treat crypto-assets differently:
| Standard | Application | Valuation |
|---|---|---|
| IAS 2 (Inventories) | If active trading | Cost or net realizable value |
| IAS 38 (Intangibles) | LT holding | Cost or revaluation (rare) |
No automatic fair value: Unlike financial assets, crypto is not "fair value through P&L" by default.
3.2 US GAAP Standards and FASB Revolution
In December 2023, FASB (Financial Accounting Standards Board) published ASU 2023-08:
Before (ASC 350):
- Crypto = intangible asset
- Historical cost
- Impairment provision (irreversible)
After (ASU 2023-08, effective 2025):
- Crypto = fair value asset
- Revaluation at each closing
- Gains AND losses in income
💡 Impact: American companies now see unrealized gains in their income. Strategy was thus able to report massive gains in 2024-2025.
3.3 International Comparison
| Jurisdiction | Standard | Valuation | Unrealized Gains |
|---|---|---|---|
| France (PCG) | ANC | Historical cost | Not recognized |
| IFRS | IAS 38 | Cost or revaluation | No (except revaluation) |
| USA (FASB) | ASU 2023-08 | Fair value | Recognized (from 2025) |
| Switzerland | Swiss GAAP | Variable | Per option |
3.4 Implications for Comparables
A French company holding Bitcoin will be less comparable to an American company:
| Company | BTC (same quantity) | Rate | FR Value | US Value |
|---|---|---|---|---|
| A (FR) | 100 BTC | Cost: $30k | $3 M | - |
| B (US) | 100 BTC | Market: $85k | - | $8.5 M |
4. Practical Implementation

5. Applicable Taxation
Corporate tax, deductible provisions, VAT exempt: complete tax overview for French companies.
5.1 Corporate Income Tax (IS)
Capital Gains Treatment:
| Situation | Tax Treatment |
|---|---|
| Realized capital gain | Taxable income (IS 15-25%) |
| Realized capital loss | Deductible from income |
| Unrealized capital gain | Not taxable |
| Impairment provision | Deductible under conditions |
IS Rates (2025):
| Profit | Rate |
|---|---|
| 0 - €42,500 | 15% (SMEs) |
| > €42,500 | 25% |
5.2 Impairment Provisions
Deductibility of crypto-asset impairment provisions is accepted by tax authorities, subject to:
- Justification of market value at closing
- Probable and non-definitive nature of the loss
5.3 VAT
Crypto-asset transactions are VAT exempt since the ECJ Hedqvist ruling (2015):
| Transaction | VAT |
|---|---|
| Bitcoin purchase | Exempt |
| Bitcoin sale | Exempt |
| Crypto/crypto exchange | Exempt |
| Services in crypto | VAT applies to service |
Consequence: VAT on related purchases (hardware, consulting) is not recoverable if main activity is crypto buying/selling (exempt activity).
5.4 Territorial Economic Contribution (CET)
- CFE: Applicable if regular activity
- CVAE: On activity value added
For simple treasury holding, no specific CET impact.

9. FAQ
Q1: Can a French company legally hold Bitcoin?
Yes. There is no prohibition. Crypto-assets are intangible movable property that any legal entity can acquire and hold.
Q2: How to value bitcoins on the balance sheet?
Under French standards (PCG), the historical cost method applies. You keep the acquisition cost on the balance sheet. If the price falls below cost, you can (must) record an impairment provision.
Q3: Are unrealized gains taxable?
No. Only realized gains (upon sale) are subject to corporate tax. Unrealized gains are neither recorded nor taxed under French standards.
Q4: Which accountant to choose?
Look for a firm with documented crypto-asset experience. The "Big Four" have dedicated practices. Specialized firms (Waltio Pro, etc.) can also support companies.
Q5: Should shareholders be informed?
Yes, for significant amounts. Information must appear in the notes to annual accounts and, depending on governance, be communicated at the General Meeting.
Q6: How to secure the company's bitcoins?
Use a regulated institutional custodian or a multisig solution with separation of duties. Avoid leaving large amounts on a standard exchange.
Q7: Does VAT apply?
No. Buying and selling crypto-assets is VAT exempt (ECJ Hedqvist 2015). Warning: this exemption may limit VAT recovery on other purchases.
Q8: What happens if the custodian goes bankrupt?
It depends on the custody legal structure. With a qualified custodian, assets should be segregated and recoverable. Check contractual terms and insurance.
