As cryptocurrencies continue to develop so does the ability of the tax authorities to monitor cryptocurrency. This development is largely due to advanced technological tools and regulatory changes designed to enhance transparency in the crypto market.

Among these tools, Chainalysis is one of the most popular tools used by tax authorities to monitor blockchain transactions. It is not currently known if the Norwegian tax authorities use Chainalysis.

The EU and the UK have already committed to mandating that all crypto exchanges operating with EU and UK clients, must share client information about their crypto activities to the local tax authorities.

This shows that it is not out of the question for us to see a similar development in Norway. If such a situation does occur you want to make sure you’ve resolved any issues with your declaration to avoid penalties.



The Consequences of non-declaration


If someone knowingly gives false or incomplete information to a government agency, or doesn't provide information they're supposed to, and they know or should know that doing so could give them tax benefits, they can be fined or sent to jail for up to two years.

How are cryptocurrencies taxed?

In Norway, cryptocurrency transactions are subject to a 22% capital income tax, encompassing trades, earnings, and other taxable events such as exchanges, sales, and purchases of goods or services with crypto. Additionally, cryptocurrencies are considered part of your net wealth for the wealth tax, which applies to net wealth exceeding 1,700,000 kroner. This includes the responsibility to declare the value of your cryptocurrencies at year-end, a crucial factor for wealth tax calculations.

It's a common misconception that only the sale of cryptocurrencies for fiat currency (e.g., NOK) triggers tax obligations. In reality, a wide array of transactions including mining, staking, and dealing with NFTs also fall within the taxable spectrum. Accurate reporting of all these transactions is essential to remain compliant with Norwegian tax laws, avoiding potential penalties and fines.
