Belgium’s New Crypto Tax: What Bitcoin and Crypto Investors Need to Know in 2026 ₿.

Belgium has long been considered relatively attractive for private investors because capital gains realized as part of the normal management of private wealth were generally exempt from personal income tax. For cryptocurrency investors, however, the landscape has now changed. Belgium has introduced a new capital gains tax on financial assets, and cryptocurrencies such as Bitcoin and Ethereum explicitly fall within its scope. The key date is 1 January 2026. Under the standard regime, qualifying capital gains realized from that date can be subject to a 10% tax, with an annual exemption designed to protect smaller investors. This represents a significant change for Belgian crypto holders.

How Did Crypto Taxation Work Before?

Before the reform, Belgium did not have a simple universal tax rate applying to every cryptocurrency profit.

The tax treatment depended heavily on the circumstances.

If someone's crypto investments could be considered part of the normal management of private assets, capital gains could generally be tax-exempt.

More speculative transactions could instead fall under the category of miscellaneous income and potentially face a 33% tax rate, while professional trading activities could be taxed as professional income.

This means that the old system was more complicated than simply saying, “crypto was tax-free.”

The circumstances surrounding the investment mattered.

💰 The New 10% Capital Gains Tax

Under the new regime, crypto-assets are included in the general category of financial assets.

For ordinary capital gains falling under the standard regime, the tax rate is 10%.

There is also an annual exemption of €10,000, subject to indexation.

Under certain conditions, unused parts of the exemption can be carried forward, potentially increasing the available exemption to a maximum indexed amount of €15,000.

This means smaller investors may still be able to realize limited annual gains without paying the new capital gains tax.

📉 What About Crypto Losses?

The legislation also recognizes that investments don't always go up.

Capital losses realized during the year can, under the applicable conditions, be deducted from taxable capital gains.

That is particularly relevant to cryptocurrency investors because crypto markets can be extremely volatile.

Imagine, for example, that an investor realizes a substantial profit on Bitcoin but also realizes a loss on another qualifying crypto investment during the same tax year.

The relevant losses can potentially reduce the amount of taxable capital gain.

However, the precise calculation depends on the applicable rules and the taxpayer's individual situation.

🗓️ What About Bitcoin Purchased Before 2026?

This is one of the most important parts of the reform.

The Belgian government specifically intended to exclude historical capital gains accumulated before the introduction of the new tax.

For assets acquired before 2026, the legislation therefore contains transitional valuation rules.

According to KPMG's analysis of the adopted legislation, taxpayers can generally use the asset's value on 31 December 2025 as the reference point for separating historical gains from gains accumulated under the new system.

In certain circumstances, the original acquisition value can also remain relevant.

This makes documentation extremely important.

🧾 Keep Records of Your Crypto

Belgian crypto investors should therefore become much more disciplined about record keeping.

Keep evidence of:

  • Purchase dates and acquisition prices
  • Sales and disposal transactions
  • Exchange statements
  • Wallet transfers
  • Transaction fees
  • Crypto-to-crypto transactions
  • Historical wallet balances
  • The value of assets around 31 December 2025

This becomes especially important when crypto has been held for several years or moved between multiple exchanges and self-custody wallets.

Blockchain transactions may be publicly traceable, but that doesn't automatically provide the tax authorities with all the context needed to determine your acquisition price and taxable gain.

🔐 What If Your Bitcoin Is on a Hardware Wallet?

Holding Bitcoin on a Ledger, Trezor or another self-custody wallet does not automatically remove it from Belgian tax rules.

Self-custody and taxation are two different things.

A hardware wallet gives you control over your private keys. It does not create a tax exemption.

Belgium is also increasing crypto transparency. In July 2026, the Belgian government confirmed regulatory changes connected to information on crypto-asset accounts being communicated to the country's Central Point of Contact for accounts and financial contracts.

Combined with European initiatives such as DAC8, the direction is clear: authorities are gaining greater visibility into cryptocurrency ownership and transactions.

⚠️ The Old 33% Rule Has Not Simply Disappeared

Another important detail is that the new 10% regime does not mean every possible crypto transaction will automatically be taxed at 10%.

Existing rules continue to matter for transactions considered speculative or carried out in a professional context.

Therefore, the exact tax treatment can still depend on how someone trades, the level of risk involved, frequency of transactions and whether the activity can reasonably be considered professional.

That distinction can make a substantial financial difference.

🚀 What Does This Mean for Belgian Crypto Investors?

Belgium is moving away from a system in which many ordinary private capital gains could remain completely tax-exempt.

For Bitcoin and crypto investors, 1 January 2026 marks an important dividing line.

Under the standard new regime, financial capital gains, including qualifying crypto gains, are taxed at 10%, while the first €10,000 of annual gains is exempt, subject to the detailed rules and indexation.

The message for Belgian crypto holders is therefore simple:

Keep your records. Know your acquisition prices. Document your portfolio around the 31 December 2025 transition date. And don't assume that moving cryptocurrency to a hardware wallet makes it invisible for tax purposes.

Bitcoin may be decentralized.

Taxes aren't. 🇧🇪₿
