Slovakia enforces a comprehensive fiscalization regime under the Law on Electronic Registers (Zákon č. 289/2008 Z. z.), obligating taxpayers to submit B2C invoice data in real-time to the Financial Administration of Slovakia (Finančná správa SR) for electronic validation. This applies to all consumer-facing sales, including cash, cards, and transfers, via certified fiscal devices or integrated POS/ERP systems that generate unique fiscal numbers and seals to deter evasion and support immediate audits.
From January 2026, Slovakia’s new Law on Sales Records (Act 384/2025 Coll.) massively narrows cash-register exemptions and makes eKasa the default for almost all sellers, strengthening real-time B2C reporting and aligning with the EU’s VAT in the Digital Age (ViDA) agenda, while broader B2B e-invoicing mandates are expected from 2027 under separate legislation.
In late 2025, the Slovak Parliament approved the Law on Sales Records (Act No. 384/2025 Coll.), effective January 1, 2026. This amends the eKasa framework under Law 289/2008 by expanding real-time reporting to nearly all sales of goods and services upon payment receipt, eliminating most exemptions for non-retail or low-volume sellers. Businesses can reference the Financial Administration's eKasa portal as the primary official resource for implementation guides, certification lists, and penalty details.
Tired of scrolling through information about e-invoicing?
Fiscalization in Slovakia is a compulsory electronic procedure where taxpayers transmit structured sales data to the Financial Administration instantly upon issuance via eKasa, receiving a unique fiscal number and digital validation to confirm transactions.
Published in 2008 and amended multiple times, the
Law on Use of Electronic Cash Registers (Zákon č. 289/2008 Z. z.) mandates real-time electronic validation of B2C sales as a key anti-evasion measure. Key elements include:
This framework combines instant B2C reporting with flexible tools, positioning Slovakia as a leader in Central European fiscal controls.
In Slovakia, B2B fiscalization via eKasa applies only to sales at retail points-of-sale where payment is received on-site, such as a company buying at checkout, requiring real-time reporting even to businesses. Pure B2B transactions outside retail premises (e.g., direct deliveries) are exempt, following standard invoicing rules.
B2C fiscalization is mandatory under Zákon č. 289/2008 Z. z. (as amended) for all point-of-sale sales to physical persons, regardless of location or payment method (cashless included). The law requires immediate recording of every retail transaction and advances “irrespective of the payment method.”
Our unified invoicing and fiscalization API integrates fiscalization directly into POS systems and is used equally for e-commerce environments.
Unlike fiscalization, Slovakia's e-invoicing mandate (under VAT Act amendments) requires structured XML for B2G since earlier, with full B2B from January 1, 2027, via the decentralized Peppol network. Voluntary pilots are ongoing for EU alignment. Full guide: E-invoicing Regulations in Slovakia
