Read more about how you calculate and declare gains and losses.

When you sell cryptocurrency, you have to calculate whether you earned a profit or suffered a loss. You calculate any profit or loss as the difference between the purchase and the selling price.

In doing so, you have to use the FIFO principle (First In First Out). This means that the cryptocurrency you bought first, is the one you sell first.

If you use one type of cryptocurrency to pay for another type of cryptocurrency, this is also considered a sale where you have to calculate profit or loss on the cryptocurrency you sold.

Each transaction must be calculated separately, which means that you can't normally offset loss on one transaction against profit on another transaction.

Read more in Danish about speculation and gifts in the section ‘Spekulationshensigten kan opgives’ (Declaration of intent of speculation) in our Danish-language legal guide

If a cryptocurrency bought for speculative purposes is lost through fraud, bankruptcy, theft, etc., you are entitled to a deduction for your loss if the following conditions are met:

• you can document your loss
• your claim is subject to the Danish Capital Gains Act (Kursgevinstloven)
• the loss is considered final which requires an individual assessment.

If the loss is due to a passcode to a virtual wallet you have lost, the contents of the virtual wallet will not be lost as the ownership of the wallet remains.

In order to be entitled to a deduction for a loss incurred on cryptocurrency bought for speculative purposes, it is a requirement that the cryptocurrency was in fact sold.

If you have bought cryptocurrency that is no longer supported by an exchange service, you are not entitled to a deduction as this is dependent on the cryptocurrency actually being sold. 

We recommend that you contact us to get a binding ruling based on an individual assessment if you are unsure of whether you are entitled to a deduction.
