DAC8 Reporting in Slovakia: Practical Guide

Slovakia has been steadily developing its digital tax infrastructure and regulatory approach to crypto-assets. The Financne riaditelstvo Slovenskej republiky (Financial Directorate of the Slovak Republic) is expected to be the competent authority for DAC8 reporting. This guide covers practical aspects of DAC8 compliance for crypto-asset service providers (CASPs) operating in or serving users in Slovakia.

Overview

DAC8 extends the EU's automatic exchange of information framework to crypto-asset transactions. CASPs operating in Slovakia should prepare to collect relevant user data and report transactions to the Financial Directorate. Slovakia already participates in CRS and FATCA reporting, and DAC8 is expected to follow a similar electronic submission model.

Competent Authority

The Financne riaditelstvo Slovenskej republiky (Financial Directorate of the Slovak Republic) is the central body of the Slovak tax administration. It coordinates tax collection, international exchange of information, and is expected to receive DAC8 reports. The Ministerstvo financii SR (Ministry of Finance) oversees tax policy and EU directive transposition.

Key Requirements

CASPs should prepare to report the following under the DAC8 framework:

• Reportable users: Individuals and entities tax resident in EU member states who conduct reportable crypto-asset transactions through the CASP.
• Transaction types: Crypto-to-fiat exchanges, crypto-to-crypto exchanges, and transfers of reportable crypto-assets are typically in scope.
• Data elements: Full name, address, date of birth, TIN (DIC for Slovak residents), transaction gross amounts, number of units, and crypto-asset type.
• Due diligence: CASPs should implement self-certification collection and TIN validation procedures as specified under DAC8 to identify reportable persons.

Submission Process

The Financial Directorate has been modernising its electronic services, and DAC8 submissions are expected to be handled digitally.

• Format: Reports should follow the OECD CARF XML schema as required by DAC8. The Financial Directorate may publish additional validation rules and technical specifications for Slovak submissions.
• Language: Official tax administration is conducted in Slovak. XML data fields should follow international standards, but correspondence and supporting materials should typically be in Slovak.
• Submission channel: The Financial Directorate may integrate DAC8 reporting into its existing electronic filing portal (portal Financnej spravy). This portal is already used for other automated exchange of information obligations. The exact method is to be confirmed.
• DIC requirement: Reporting entities will need a Slovak DIC (Danove identifikacne cislo) for electronic filings.

Important Dates

• Transposition deadline: December 31, 2025 (directive must be incorporated into Slovak law)
• Data collection begins: January 1, 2026 (reporting entities should start collecting relevant information)
• First reporting period: Calendar year 2026
• First reports due: 2027 (exact date to be confirmed by the Financial Directorate)

Practical Tips

• Register with the Financial Directorate: Ensure your entity is properly registered and has electronic access to the portal Financnej spravy.
• Monitor the Zbierka zakonov: All transposing legislation will be published in Slovakia's Collection of Laws. Check regularly for implementing acts and ministry decrees.
• Collect DIC numbers accurately: Ensure your systems can capture and validate Slovak 10-digit tax identification numbers during onboarding.
• Prepare Slovak-language capabilities: Your compliance team or local advisors should be equipped to communicate with the Financial Directorate in Slovak.
• Leverage CRS experience: If you already submit CRS reports in Slovakia, evaluate how existing workflows and data collection processes can be extended for DAC8.
• Coordinate with NBS: The Narodna banka Slovenska (NBS, National Bank of Slovakia) may be involved in MiCA licensing. Be aware of potential overlap between DAC8 reporting and NBS regulatory requirements.
• Engage local professionals: Consider working with Slovak danovi poradcovia (tax advisors) experienced in international exchange of information and crypto-asset taxation.
