Denmark Becomes First Country to Tax Unrealized Crypto Gains

Starting on January 1st, 2026, the Danish government will impose a 42% tax on unrealized gains from crypto assets.

This tax will apply not only to any new crypto bought after that date but also to crypto acquired as far back as January 2009—the time of the first Bitcoin “genesis block.”

What Does “Unrealized Gains” Mean?

Unrealized gains are profits you haven’t cashed out yet. Let’s say you bought some Bitcoin years ago, and its value has gone up since then. Even if you haven’t sold it, Denmark’s new law says you still owe taxes on the increased value. That’s what’s meant by taxing “unrealized gains.”

It’s like taxing the money you’ve made on paper, even if it hasn’t hit your bank account yet. In Denmark, if the value of your Bitcoin or other crypto goes up, you’re expected to pay a 42% tax on that increase—even if you haven’t sold any of it.

The law will also apply to any crypto obtained as far back as January 3, 2009, when Bitcoin was first created. That means if someone in Denmark has been holding onto their Bitcoin for more than 15 years. They will have to pay taxes on how much that Bitcoin has grown in value over time—even if they never sold a single coin.

Why Is Denmark Doing This and What Does This Mean for Crypto Users?

Denmark’s government says this is a way to make sure everyone pays their fair share. As crypto grows in popularity, governments are looking for ways to regulate and tax it. By taxing unrealized gains, Denmark wants to prevent people from avoiding taxes just by holding onto their crypto.

For crypto holders in Denmark, this tax could be a big deal. Some may feel like they’re “between a rock and a hard place”. They will have to pay taxes on money they haven’t received. Others might decide to sell some of their crypto to cover the tax bill. Either way, it’s a major change that will surely shake up the crypto world.
