Executive Summary
Slovakia’s tax landscape is dominated by three high-impact developments: the imminent mandatory B2B e-invoicing regime effective 1 January 2027, a record-breaking surge in transfer pricing audit yields reaching €52.4 million in 2026, and continued aggressive excise enforcement preventing €88 million in revenue leakage through illicit tobacco trade. These initiatives signal a strategic shift toward real-time digital VAT compliance, intensified scrutiny of multinational profit allocation, and robust protection of indirect tax revenues.
Important Updates
Mandatory B2B E-Invoicing (eFaktúra) Effective 1 January 2027
Starting 1 January 2027, all VAT-registered entities in Slovakia must issue and receive structured electronic invoices in EN 16931 format via a certified digital postman (digitálny poštár) for domestic B2B transactions. Paper and simple PDF invoices will no longer support VAT deduction. The Financial Administration has contacted over one million taxpayers via their electronic mailboxes, urging them to select from nearly 100 certified providers and complete contractual and technical integration before year-end. The regime, implementing the EU ViDA package under Act No. 321/2024 Coll., aims to reduce the VAT gap through automated pre-filled returns and real-time transaction visibility.
Accountants and tax advisors receive dedicated guidance on delegated access, bulk processing via API, automated validation, and 10-year compliant archiving, relieving firms of separate archival obligations. However, legal liability for correct invoicing remains with the taxpayer. Non-compliance risks denial of VAT deduction, fines up to €5,000 per incorrect invoice, and potential audits. Multinational groups with Slovak subsidiaries must ensure local compliance, as the mandate covers domestic B2B and B2G supplies.

Excise Enforcement Prevents €88 Million Revenue Loss via Illicit Tobacco Seizures
The Criminal Office of the Financial Administration reported interim results for January 2024–September 2026, revealing the prevention of €88 million in excise duty and VAT leakage. Operations dismantled 18 illegal cigarette factories, seized nearly 172 million counterfeit cigarettes and over 364 tonnes of raw tobacco (equivalent to 500 million cigarettes). The enforcement leverages the EU track-and-trace system (Regulation 2018/574), advanced data analytics, and cooperation with OLAF and Europol, reflecting a shift from small-scale smuggling to large-scale industrial illegal production linked to organised crime.
Legitimate tobacco manufacturers, distributors, and retailers benefit from reduced unfair competition, while the state safeguards a significant indirect revenue stream. Licence holders must maintain strict adherence to Excise Duty Act conditions, EMCS movement monitoring, and immediate irregularity reporting. Non-compliance risks licence revocation, fines up to €1 million, and criminal prosecution. The Financial Administration signalled continued high-intensity controls and urged public reporting via its anonymous hotline.

Transfer Pricing Audit Yields Surge 370% to €52.4 Million in 2026
The Office for Selected Business Entities (ÚVHS) reported record transfer pricing adjustments exceeding €52.4 million in 2026, a nearly 370% increase over €11.17 million in 2025. TP audits now constitute over 60% of ÚVHS activity, driven by enhanced use of Country-by-Country Reporting data, Master File/Local File documentation, and focus on intangibles, financial transactions, and business restructurings. The DEMPE framework for IP valuation, increased APA audits, and deeper cross-border cooperation via EU Joint Audits and OECD MAP underpin the surge.
Multinational enterprises above the €50 million CbCR threshold and large domestic groups in automotive, IT, pharma, finance, and shared service centres face heightened scrutiny. Adjustments often trigger secondary adjustments, withholding tax assessments, and VAT consequences, with penalties up to 100% of underpaid tax for inadequate documentation. Taxpayers are urged to proactively review TP policies, conduct benchmarking, ensure documentation consistency, and consider voluntary disclosure to mitigate penalties. ÚVHS plans further capacity expansion in 2027.
