Crypto tax 2025: how to report crypto in box 3

How is crypto taxed in the Netherlands?

For private individuals, crypto usually falls in box 3. You report the value in economic terms on the 1 January reference date, using the exchange rate of the platform you use for conversion. In special situations, such as active trading or mining, box 1 may become relevant.

How box 3 works for 2025

• The Belastingdienst looks at the value of your crypto on 1 January 2025
• The box 3 tax-free allowance is EUR 57,684 per person or EUR 115,368 with a fiscal partner
• The box 3 tax rate is 36%

If your total box 3 assets stay below the threshold, you generally do not pay box 3 tax.

Deemed return percentages

For the standard 2025 box 3 calculation, crypto is treated as an investment or other asset with a deemed return of 5.88%. Bank balances use 1.37% and debts 2.70%.

For the 2025 return you can also report your actual return. The Belastingdienst then compares the deemed and actual return and uses the more favorable result.

Which crypto do you report?

In principle, all crypto assets you own form part of your tax position: Bitcoin, Ethereum, altcoins, stablecoins, NFTs, exchange balances, wallet holdings, and many DeFi positions.

How do you determine the value?

You need the market value on 1 January 2025. Use the rate of the exchange or platform you rely on for conversion and keep evidence of how you arrived at the value.

Example

If on 1 January 2025 your crypto portfolio is worth EUR 55,020 and you have no other box 3 assets, you remain below the EUR 57,684 threshold and generally owe no box 3 tax. If you also have bank balances or investments, the combined position can push you above the threshold.

Common mistakes

• Not reporting crypto at all
• Forgetting assets spread across multiple exchanges or wallets
• Using the wrong reference date
• Ignoring NFTs or DeFi positions
• Confusing private investing with activities that may belong in box 1

When does box 1 apply?

Box 1 can become relevant if your crypto activities go beyond normal private asset management, for example in cases of very active trading, organised mining, or business-like activity. That boundary is fact-specific, so if you are in doubt, get advice.
