Bybit and taxes in Belgium: spot, derivatives and your 2026 return

Last updated: 11 June 2026 · Reading time: 8 minutes

Bybit is one of the largest international crypto exchanges, popular with Belgian investors who want to go beyond the entry-level platforms. But as soon as the filing season starts, one question lingers: what exactly do I need to declare from my Bybit account, and how is it taxed?

Since 1 January 2026, the answer is partly fixed in law. The capital gains tax on financial assets, approved on 3 April 2026 by the Chamber and published in the Belgian Official Gazette on 21 April 2026, regulates for the first time how crypto gains are taxed in Belgium. On top of that, rules that have been around longer also apply: the reporting obligation for foreign accounts (CAP) and the declaration of staking and other income.

In this guide we go through all the tax obligations for anyone with a Bybit account, how to correctly import your spot transactions into Cryptotax, and the mistakes we see most often.

🎯 The short version (TL;DR)

• Spot sales and conversions from 1 January 2026: taxable at 10% above an exemption of EUR 10,000 per year.
• Selling to a stablecoin (for example BTC to USDT) counts as a sale for tax purposes, even though you received no euros in your bank account.
• Bybit Earn and staking rewards: taxable as movable income (roerende inkomsten) or miscellaneous income (diverse inkomsten) at the moment of receipt.
• Derivatives (futures, perpetuals) fall under a separate regime and are not included in the spot export. See our guide on crypto derivatives.
• CAP report: your Bybit account must be reported once to the Central Point of Contact (CAP) of the National Bank, plus a mention in Box XIII (Vak XIII).
• Import: Cryptotax reads the Bybit Spot Trade History export automatically and records each fill as a sale or purchase.

📊 Which Bybit activity is tax-relevant?

Not every action on Bybit leads to tax, but there are more than many people think. Concretely:

The most important pitfall is in the third row: a conversion or a sale to a stablecoin is, for tax purposes, exactly the same as a sale. Anyone who converts their BTC to USDT to "step out of the market for a bit" realises a taxable capital gain at that moment, even though no euros came back. Many investors forget this and therefore underestimate their taxable base.

⚖️ How is each type taxed?

Spot capital gains: 10% above EUR 10,000

The capital gains tax of 6 April 2026 taxes capital gains on financial assets, including crypto, at 10%. The main rules:

• Applies to capital gains realised from 1 January 2026.
• The first tranche of EUR 10,000 per year is exempt (indexed from 2027).
• Rate: 10% on the balance above the exemption.
• Cost basis per asset via the weighted average, not FIFO.
• For crypto you already held before 2026, your cost basis is the market value on 31 December 2025 (the step-up).
• No withholding tax at source: you report it yourself via your tax return.

Bybit Earn and staking

Rewards from Bybit Earn, savings or staking are not taxed as a capital gain, but as income, at the moment of receipt and at the value at that moment. For those who participate passively, this is usually movable income (roerende inkomsten) (30%); for those who manage very actively it can be miscellaneous income (diverse inkomsten) (33%). More detail in our staking guide.

Derivatives and futures: a separate story

The "prudent person" test

Anyone who trades very actively on Bybit (day trading, large volumes, leverage) may fall under the speculative regime, where capital gains are taxed as miscellaneous income (diverse inkomsten) at 33% instead of the 10% capital gains tax. Since April 2026, the Ruling Commission (Dienst Voorafgaande Beslissingen) has applied a stricter threshold: more than 25% of your financial assets in crypto, combined with frequent trading, can already be enough to lose the "prudent person" (bonus pater familias) qualification. If in doubt, read our guide on the prudent person test.

🏦 CAP report of your Bybit account

In addition to the tax on your transactions, the Bybit account itself must be reported once to the Central Point of Contact (CAP) of the National Bank, because Bybit is a foreign platform. The capital gains tax law of April 2026 makes this obligation explicit for crypto accounts.

Which entity and which country? Since 2025, users in the European Economic Area have been served via Bybit EU GmbH, with its registered office at Donau-City-Straße 7, 1220 Vienna, Austria. That entity holds a MiCA licence (CASP) from the Austrian regulator FMA (granted on 28 May 2025) and serves EEA users via the bybit.eu platform. Anyone who still traded on the global platform (bybit.com) before the migration held an account with the international Bybit entity in Dubai. State the country corresponding to the entity where your account is held: for EEA users, usually Austria.

• One-time, not annual.
• Portal: cappcc.nbb.be, log in with eID or itsme.
• Deadline: 30 June, together with the personal income tax return.
• Penalty for non-declaration: EUR 50 to EUR 1,250 per account, plus an extension of the investigation period to 7 years.

For the full step-by-step explanation, see our CAP declaration guide and the checklist for foreign exchanges.

📑 Bybit in Box XIII (Vak XIII) of your return

In your annual personal income tax return, you confirm in Box XIII (Vak XIII), section A that you have a foreign account and that you have reported it to the CAP. You only fill in the country, no balance or amounts. Your actual gains and income go into other boxes, depending on the category.

📤 Importing your transactions into Cryptotax

Bybit does not offer an API connection for tax tools in Cryptotax, but the Spot Trade History export already contains all your spot fills with the exact quantities and prices.

Step 1: export your Spot Trade History from Bybit

1. Log in to bybit.com.
2. Go to Orders and choose Spot Order.
3. Open the Trade History tab.
4. Choose the full period, not just the current year.
5. Click Export and download the CSV file.

Step 2: upload the CSV file into Cryptotax

1. Log in to cryptotax.be.
2. Go to Data sources and click Add source.
3. Select Bybit from the list.
4. Drag the CSV file into the upload zone, or click to browse.
5. Click Import.

Cryptotax recognises the Bybit Spot format and converts each fill into the correct event type: a purchase records cost basis, a sale or conversion is recorded as a disposal, and trading fees are included so that they reduce your capital gain.

Step 3: check the imported data

Go through the overview and pay particular attention to:

• Sales to USDT: these are correctly recorded as a disposal, not as an internal move.
• Withdrawals to your own wallet: if you also add that wallet (Ethereum, Base, Arbitrum, Solana), the transfer is recognised as an internal transfer and not counted as a sale.
• Data warnings: an unknown token price or unrecognised counterparty gets a flag. Those flags are points of attention, not errors.

⚠️ The mistakes we see most often

1. Not declaring stablecoin sales. BTC to USDT feels like "stepping out of the market", but for tax purposes it is a sale.
2. Forgetting derivatives. Futures profit falls outside the spot export and must be treated separately.
3. Exporting only the current year. Without the full history, your cost basis is wrong.
4. Skipping the CAP report. Bybit is a foreign platform, so the reporting obligation applies in full.

❓ FAQ: frequently asked questions

Do I have to pay tax if I only bought crypto and sold nothing?
No. The mere holding of crypto does not lead to tax. Only on a sale, conversion or reward does a taxable event arise. You do, however, have to report the Bybit account itself via the CAP.

Does a sale to USDT count as taxable?
Yes. For tax purposes, a stablecoin is a different asset from the coin you sold. The conversion realises your capital gain, even without a euro transaction.

I traded futures on Bybit. Is that included in the import?
No. The Spot Trade History contains only spot fills. Derivatives fall under a separate regime (usually miscellaneous income (diverse inkomsten) 33%) and you treat them separately. Read the derivatives guide.

What if I made a loss in 2026?
Losses can be offset within the same tax year against gains on other financial assets, but there is no carry-forward to subsequent years.

And what if I also use Binance, Kraken or Bitvavo?
Every foreign exchange follows the same logic. We have separate guides for Binance, Kraken, Coinbase and Bitvavo.

🔮 What changes with DAC8?

From 1 January 2026, crypto platforms collect data on their Belgian customers under DAC8, the European directive for the automatic exchange of crypto information. From September 2027, that data will be reported annually to the Belgian tax authorities. Anyone who gets their return in order today avoids a targeted audit tomorrow due to a mismatch. Read our DAC8 update for Belgium.
