MiCA is everywhere these days, and a lot of inaccuracies circulate about its impact on taxes. Let's clear it up: what MiCA actually covers, what it doesn't, and why it will still change the way you report your cryptocurrencies.

What MiCA is

MiCA (Markets in Crypto-Assets, EU Regulation 2023/1114) is the first unified regulatory framework for crypto-assets across the entire European Union. It rolled out in phases — rules for stablecoins from mid-2024, and rules for service providers (so-called CASPs — exchanges, custody, brokers) from the end of 2024. Existing providers had a transitional period that ends across the EU no later than 1 July 2026. After that date, every crypto exchange or custody service operating in the EU must hold a valid MiCA licence.

MiCA's goal is consumer protection, market transparency and unified rules: licensing of exchanges, reserve requirements for stablecoins, and market-abuse rules. A single licence is valid in all 27 member states (so-called passporting).

MiCA is not a tax law

This is the most common misunderstanding. MiCA says nothing about how much tax you pay on your crypto gains. Cryptocurrency taxation in Slovakia is still governed by Act No. 595/2003 Coll. on Income Tax — and that does not change because of MiCA. Rates, the holding-period test and the way you file are not directly affected by MiCA.

In other words, even after MiCA is fully in effect, the same rule applies as before:

Simply holding cryptocurrency (HODL) is not a taxable event. The tax liability arises only on a sale, on exchanging one cryptocurrency for another, or on paying with crypto for goods or services.

Where MiCA does reach you: transparency

The indirect but very real impact of MiCA on taxes comes through transparency. Alongside MiCA, the DAC8 directive and the international CARF framework (Crypto-Asset Reporting Framework) are coming into force. From 2026, licensed crypto-asset service providers begin collecting transaction data on their clients, and the first automatic exchange of this information between EU member states' tax authorities is expected in 2027.

In practice this means exchanges and custody services will report on your trades, and the tax administration will have access to that data. The era when unreported crypto could simply be "forgotten" is rapidly ending.

What to do as a Slovak investor

  • Keep records from day one. For every sale or exchange you will need to prove the purchase price in euros, the dates and the values. An export from your exchange (CSV) is the foundation.
  • Report honestly. As transparency grows, so does the risk of a mismatch between what the exchange reports and what you declare in your return.
  • Consider your structure. An individual reports crypto gains as other income (§ 8) at a 19/25% rate plus health contributions. A company (s.r.o.) has a 10% income tax rate up to €100,000 of profit and pays no health contributions on profit — for regular trading it can be significantly more advantageous.

Summary

MiCA changes the rules of the game for exchanges and service providers, not tax rates directly. But together with DAC8 and CARF it brings a level of transparency to crypto that we have not had before — and that makes correct, timely reporting more important than ever.
