Slovak VAT registration

In Slovakia, the requirement to register for value added tax (VAT) depends on whether the business is established in Slovakia and the nature of the taxable activities carried out.

For Slovak-established businesses, VAT registration is generally required once annual taxable turnover exceeds €50,000 within a calendar year. This is the statutory domestic threshold under the Slovak Value Added Tax Act. Businesses below this threshold are not required to register for VAT unless they choose to register voluntarily or carry out activities that trigger mandatory registration.

There is no VAT registration threshold for nonresident businesses. Foreign businesses making taxable supplies in Slovakia must generally register for VAT from the first taxable supply unless the reverse-charge mechanism fully applies.

Slovak businesses making cross-border B2C supplies of goods or services to customers in other EU member states must consider the EU-wide €10,000 OSS threshold for total cross-border EU sales. Once this threshold is exceeded, VAT must be charged in the member state of consumption. The supplier may register locally in each member state or elect to use the EU One-Stop Shop (OSS) scheme.

Apart from the domestic €50,000 threshold for Slovak-established entities, there are no general simplification thresholds. VAT registration is typically mandatory once the relevant taxable activity is undertaken, particularly for nonresident or cross-border business models.

To register for VAT in Slovakia, applicants (resident or nonresident) typically need to provide:

• A completed VAT registration application submitted to the Financial Administration of the Slovak Republic (Finančná správa)
• Legal entity details: company name, legal form, country of incorporation, registered address, directors or managers
• Description of business activities and expected Slovak taxable turnover
• Details of taxable supplies to be made in Slovakia
• Power of attorney for a tax representative, where required (particularly for certain non-EU applicants)
• Banking and contact details for VAT correspondence
• Supporting documentation demonstrating the nature of Slovak activities (especially for nonresident applicants)

Applications are submitted to the Financial Administration, generally through its electronic systems. VAT registration should generally be completed before taxable supplies begin, as late registration may result in penalties or backdated VAT assessments.

Once approved, the Financial Administration issues a Slovak VAT number. Registration timelines may vary depending on the completeness and complexity of the application.

• Structure: SK + 10 digits (for example, SK1234567890)

• The SK prefix is used for EU VAT identification and verification purposes, including validation through the VAT Information Exchange System (VIES).

After registering for VAT in Slovakia, businesses must comply with ongoing VAT obligations, including:

• Filing periodic VAT returns (generally monthly or quarterly, depending on turnover and registration status)
• Charging and collecting Slovak VAT at the applicable rates (standard rate 23%)
• Issuing VAT-compliant invoices in accordance with Slovak and EU invoicing rules
• Submitting EC Sales Lists (recapitulative statements) and Intrastat reports where applicable
• Maintaining VAT records and accounting documentation in line with Slovak legislation
• Using the One-Stop Shop (OSS) where applicable for EU cross-border B2C supplies
• Paying VAT due by the statutory deadlines

Failure to comply with Slovak VAT requirements may result in penalties, interest charges, and enforcement action by the Financial Administration of the Slovak Republic, particularly in cases of late registration, incorrect filings, or unpaid VAT liabilities.
