Will Norway find out about my crypto investments?

In 2025, the Norwegian authorities are intensifying checks on cryptocurrency transactions and introducing new rules to prevent digital assets from being hidden. It is estimated that at least 300,000 Norwegians own cryptocurrency, but only around 54,000 reported it in the return for 2023 - which means many investors still do not declare crypto in their own tax return.

Below we explain how Norwegian authorities may find out about the cryptocurrency you hold and what tax obligations apply to you - both as a private individual and (briefly) in the case of businesses. The article reflects the legal position in 2025.

Control of cryptocurrency by Norwegian authorities

In Norway, the principle of voluntary declaration of income and assets applies - it is the taxpayer's responsibility to report any cryptocurrency and other assets held (such as property, cash, bank account balances, vehicles, gold, securities, etc.) in the annual tax return (skattemelding).

However, Skatteetaten may audit a taxpayer and compare their declarations with external sources of information. If, for example, you withdraw large sums from the sale of crypto into a bank account, the bank (in accordance with anti-money laundering rules) may pass the information to the authorities, who will then become interested in the origin of the funds.

The Norwegian authorities are signalling that in 2025 they are focusing on crypto investors: more audits have been announced and additional penalty tax (tilleggsskatt) is already being imposed for not disclosing income from cryptocurrency. In other words, the number of audits is rising because many investors still do not report their crypto - only around 54,000 taxpayers declared cryptocurrency in the return for 2023, while the number of owners is estimated at over 300,000.

Skatteetaten already has a list of known Norwegian crypto platforms and tools for analysing bank transfers, so hiding larger cryptocurrency investments is becoming increasingly difficult.

International exchange of information (CRS and CARF)

Norway takes part in global systems for the exchange of tax information. Since 2017, the OECD Common Reporting Standard (CRS) has applied - the Norwegian tax authorities receive automatic annual data on foreign bank accounts, securities and other financial assets belonging to their tax residents (and also pass information on foreign nationals' accounts in Norway to other countries).

However, cryptocurrency has not so far been covered by CRS, because crypto exchanges are not regarded as traditional financial institutions and have not had to report user accounts. This is changing - in response to this gap, the OECD has developed a new Crypto-Asset Reporting Framework (CARF). CARF provides for the automatic collection and exchange of information on cryptocurrency transactions and holders between the tax administrations of different countries.

In November 2023, Norway, together with many countries (including EU states), signed an agreement to implement CARF (and the updated CRS) - the rules are due to enter into force from 1 January 2026. This means that in a few years' time data on cryptocurrency transactions will be exchanged between countries in the same way as information on bank accounts. Norway is already preparing domestic rules to meet these international obligations.

Reporting obligations for exchanges

Crypto exchanges and platforms play an important role in giving authorities access to crypto data. At present, many exchanges carry out KYC (know your customer) and AML (anti-money laundering) procedures, collecting user data, but not all of them automatically report it to the tax office. Norway is seeking to change this.

The government has drafted rules imposing an obligation on Norwegian exchanges and crypto custodians to report information about their customers to Skatteetaten. This information is to include, among other things, users' identification details, the value of the cryptocurrency they hold and transaction history. Importantly, Norway plans to share data obtained from domestic exchanges with other countries and to receive equivalent information from foreign authorities about Norwegian residents using exchanges outside Norway.

The proposed rules go even further than the OECD standard - they provide for reporting not only transactions but also crypto holdings (the so-called innestående verdier - "remaining values" on the account). As a result, hiding cryptocurrency on a foreign exchange will become risky, because in future this data will end up with the Norwegian tax authorities anyway through automatic exchange of information. It is already worth remembering that if you use a Norwegian crypto platform, the tax authorities may gain access to it - local entities (for example the exchanges Firi, K33, NBX, etc.) are supervised and registered (in 2023 there were 12 such companies registered with Finanstilsynet) and will soon be covered by the new reporting obligation.

Tax on cryptocurrency in Norway - obligations for private individuals

Cryptocurrency (Norwegian: kryptovaluta) is treated in Norway as an asset - formue. This means that you must include the cryptocurrency you hold in your tax return. In practice, every Norwegian tax resident who holds cryptocurrency at the end of the year or has earned income from it during the year has the following obligations:

• Declare held cryptocurrency as assets (formue) - in the annual return you must state the market value of the coins/tokens you hold on 31 December. Cryptocurrency is not subject to any valuation relief - it is counted at 100% of market value. This value is converted into NOK at the year-end exchange rate. If the total value of your assets (including cryptocurrency) exceeds the wealth tax allowance (formuesskatt) - NOK 1.76 million for a single person (2025), NOK 3.52 million for married couples (2025) - the excess is taxed at 1% per year (or more, after exceeding NOK 20 million).
• Settle capital gains from cryptocurrency - if during the year you sold cryptocurrency at a profit, exchanged it for other assets at a profit or otherwise realised income, you must declare taxable income subject to a 22% rate (applicable to capital income). For example, a profit from selling Bitcoin is treated in the same way as a profit from selling shares - the tax is 22%.
• Settle losses - if you incurred a loss on cryptocurrency transactions (for example, you sold coins below the purchase price), you can deduct that loss from income - this gives a tax relief equivalent to 22% of the loss. Norwegian rules also allow a loss caused, for example, by theft or fraud (loss of funds from an exchange) to be deducted, provided it is documented.
• Report all taxable events - almost every disposal of cryptocurrency is taxable. The taxpayer should report every transaction or income item related to crypto that affects their financial position. Typical taxable events include: selling cryptocurrency for traditional currency (FIAT), exchanging one cryptocurrency for another (for example trading or buying an NFT with crypto), paying for goods/services with cryptocurrency, receiving passive income in cryptocurrency (interest, staking, airdrops), mining new coins, and even receiving salary or a bonus in cryptocurrency from an employer. All these situations are treated as a realisation of gain or a disposal/loss of assets, which under the rules creates a tax obligation.

It should be remembered that the responsibility for correctly settling cryptocurrency lies with the taxpayer. This means that you must enter the transaction values and assets held yourself in the tax return. In 2025, the Norwegian tax office does not automatically fill in crypto information in your return, so it is important to include these details yourself.

To make this easier, many taxpayers use special tools or apps to track transactions and generate reports (for example Kryptosekken). Failure to report cryptocurrency or providing incorrect information may lead to serious consequences, as explained below.

Penalties for not reporting cryptocurrency

Not disclosing cryptocurrency holdings or income from them in Norway is treated as concealing the tax base. If Skatteetaten discovers that a taxpayer has not reported cryptocurrency, it may impose back tax together with interest and a substantial financial penalty.

Normally, additional tax (tilleggsskatt) of 20% of the concealed tax amount is imposed. In more serious cases, the rate of penalty surcharges is 40%, and where deliberate tax fraud is proven - even 60%. Norwegian law allows the tax authorities to pursue arrears up to 10 years back in the case of serious breaches. This means that if you have not reported crypto for the past decade, the authorities may demand payment of the tax due for all those years plus a 60% penalty on top - a very high sanction.

There are indeed cases where Skatteetaten applies the maximum 60% penalty surcharge in cryptocurrency cases. However, this is rare and happens only where deliberate action is proven. In addition, deliberate concealment of income on a large scale may lead to criminal proceedings (tax fraud charges) - in extreme situations, fines and even imprisonment may be imposed.

If you realise that you did not declare your cryptocurrency in previous years, Norwegian law gives you a chance to make a voluntary correction. You can make a so-called voluntary correction (frivillig retting) - report the outstanding income and assets on your own initiative before the authorities themselves begin an audit or receive information about your cryptocurrency from other sources. Skatteetaten accepts such self-reporting - it will assess the back tax and interest, but will waive the penalty (tilleggsskatt). There is one condition: you must come forward before the authorities summon you for explanations or before they receive data about your assets (for example through information exchange from abroad). So if you have undeclared crypto from previous years, it is better to consider voluntary disclosure now to avoid severe sanctions.

Cryptocurrency in a company - obligations for businesses

We will briefly mention what the situation looks like when a company holds cryptocurrency.

In Norway, businesses (companies) are also taxed on gains from crypto investments. Cryptocurrency is a company asset and must be included in the accounts and financial statements in accordance with accounting and tax rules. If a company makes profits from selling or exchanging cryptocurrency, these are taxed on the same basis as other company income.

Importantly, companies do not pay wealth tax (formuesskatt) - this applies only to private individuals, so the value of crypto held by a company is not subject to annual wealth tax (however, if you are the owner, the value of your company's shares/ownership interests is included in your personal wealth subject to formuesskatt).

Companies engaged in trading or mining cryptocurrency on a large scale are simply treated as business entities - their income from cryptocurrency is taxed like ordinary business income. Attempting to hide company cryptocurrency from the tax office would be just as illegal as in the case of private individuals - similar financial penalties and tax liability apply.

Summary

Yes - Norway may find out about your cryptocurrency. Thanks to domestic checks, reporting by exchanges and international information exchange, Skatteetaten has increasing access to data about your investments. Hiding crypto is becoming more and more risky, and the penalties can be severe. If you have not reported crypto before - it is better to do so before the tax authorities do it for you.

It is not worth assuming that crypto will remain anonymous - it is better to meet your tax obligations, declare cryptocurrency and pay the tax due. Norwegian law guarantees clear tax rules (22% on capital gains, the possibility of deducting losses) and relatively low rates, so settling matters honestly is safer. Avoiding taxation of cryptocurrency can, however, result in very severe financial penalties and even criminal liability. In other words - Norway may well find out about your crypto investments, so it is better to inform the tax authorities yourself before they demand the back tax.
