Transfer Pricing in Slovakia

The legal framework

Slovak transfer pricing law is unusually self-contained. The arm's length principle sits in the Income Tax Act No. 595/2003 Coll. itself: § 17(5) requires a related party to add back to its tax base any difference by which prices or conditions in significant controlled transactions depart from those independent parties would have agreed, where the difference reduced the base or increased a loss, while § 18(1) defines the principle and its comparability factors. Since 1 January 2023 the statute also points expressly to the OECD Transfer Pricing Guidelines methodology — converting the Guidelines from a persuasive aid (the Ministry of Finance published Slovak translations in the Financial Bulletin as early as 1997) into a statutory source of interpretation.

The related-party net is wide. Economic or personal connection begins at a 25% direct, indirect or indirect-derived share of capital, voting rights or profits (§ 2(o)); indirect interests multiply through the chain, and once an indirect-derived interest reaches 50%, every person in the calculation chain is deemed connected regardless of actual stake. Holdings of close persons and parties acting in concert are aggregated, and the 'other connection' category of § 2(p) captures any relationship established mainly to erode the tax base — an anti-avoidance backstop with no ownership threshold at all. Purely domestic transactions are covered as fully as cross-border ones, as are dealings between a head office and its permanent establishment. One important carve-out: since 2023 only 'significant' transactions — above EUR 10,000, or EUR 50,000 of principal for loans — engage the machinery at all (§ 17(5)(a)). Note too that Slovakia rejects the Authorised OECD Approach: all its treaties carry pre-2010 Article 7, and notional intra-entity dealings attract no mark-up, interest or royalties.

Methods, comparables and the median rule

§ 18(2)–(3) codifies the five OECD methods — CUP, resale price, cost plus, profit split and TNMM — plus combinations or any other approach consistent with the arm's length principle. There is no hierarchy; the most appropriate method standard governs. The Financial Directorate's 2013 methodological guideline fills in practice: test the less complex party (Slovak or foreign), draw comparables from commercial databases, and aggregate only same-type, interlinked transactions concluded under similar conditions — a point administrative courts pressed in 2024, holding that aggregation in documentation must be properly justified.

The regime's sharpest edge is the statutory median rule. Since 1 January 2023, where an audit finds the taxpayer's result outside the range of independent comparable values, § 18(1) directs the adjustment to the median — unless the taxpayer demonstrates that another value within the range is more appropriate. The interquartile range remains administrative practice, not law; only the median default is codified. The practical burden sits squarely on the taxpayer to defend a specific point in the range, not merely membership of it. Secret comparables are not used, and domestic comparables are preferred where comparability holds, but there is no Slovak-only screen.

Two deliberate gaps matter. Slovakia has not adopted the Chapter VII simplified approach for low value-adding services: every management charge faces the full benefit test plus the § 17(5)(b) deduction conditions — demonstrable link to the taxpayer's activity, a third-party willingness-to-pay test, proven allocation, and capture in the records. And related-party interest runs into the 25%-of-EBITDA caps of § 21a and, since 1 January 2024, the ATAD-based § 17k.

Documentation: what Finančná správa expects

Documentation content is set by Ministry of Finance guideline, currently MF/012879/2025-724 (published 15 October 2025, replacing MF/020061/2022-724). It applies to documentation for tax periods whose return-filing deadline expires after 31 December 2025 — in practice, FY2025 files onward. Three tiers survive. Full documentation — a general group part and a specific part mirroring the OECD master file and local file — is triggered by, among other things, cross-border controlled transactions exceeding EUR 10 million, IFRS reporting in separate accounts, dealings with non-cooperative jurisdictions, investment-aid tax relief, or any transaction covered by an APA, § 17(6) adjustment or MAP request. Basic documentation captures taxpayers with revenues above EUR 8 million or cross-border transactions above EUR 1 million. Everyone else can now discharge the duty simply by completing the tax return properly — which is where the real 2026 change bites.

Table I of the new DPPOv25 corporate return demands per-transaction disclosure of every significant controlled transaction, regardless of documentation tier: up to 99 rows with transaction-type codes, counterparty name and country, values and tax-base impact. It is, in substance, an annual transfer pricing return — and an audit-selection database. Documentation itself is never filed; it must be produced within 15 days of a request, which may arrive the day after the filing deadline. It may be kept in any language, but a Slovak version is due within 15 days if demanded. CbC reporting follows the standard EUR 750 million threshold under Act No. 442/2012 (§§ 22a–22g), with a 12-month filing window and a notification due with the return.

Audits, penalties and the enforcement climate

An assessed transfer pricing difference attracts a penalty of three times the ECB base rate per annum — never less than 10% p.a. — computed per day from the original due date, floored at 1% and capped at 100% of the additional tax (§ 155 Tax Procedure Code). § 18a ITA doubles that where the assessment was combined with the anti-abuse rules (§ 50a or substance-over-form), though the doubling falls away if the taxpayer forgoes appeal and pays within the appeal window — a deliberate settlement lever. Failing to produce documentation on time costs EUR 100 to EUR 10,000 under § 155(1)(e) (the OECD profile's EUR 30–3,000 figure reflects the superseded range), softened by a statutory 'second chance': no range-based fine on a first breach. Assessments are time-barred after five years, but ten where a tax treaty applies — which covers most cross-border TP cases.

The enforcement climate has hardened. The Financial Administration has announced closer scrutiny of the economic substance of controlled transactions, manufacturer and distributor characterisation, intra-group loans, cash pooling and guarantees, persistently loss-making entities, and counterparties in jurisdictions such as the Netherlands and Cyprus. Published court practice remains thin — the first comprehensive TP judgment came from the Košice administrative court, and Supreme Administrative Court decisions such as 4Sfk/89/2022 deal with related-party deductibility rather than methodology — so most disputes are still won or lost at audit and on appeal before the Financial Directorate.

Dispute resolution and advance certainty

Slovakia runs a full APA programme under § 18(4)–(10): unilateral decisions and treaty-based bilateral or multilateral agreements, requested at least 60 days before the first covered period, issued for up to five tax periods and extendable for five more. In bilateral cases the competent authorities may agree to cover additional periods, giving roll-back flexibility, and adjustments made to implement a treaty APA are not penalised. Fees are EUR 10,000 (unilateral) and EUR 30,000 (bilateral or multilateral), halved for taxpayers rated highly reliable under the tax reliability index — and forfeited on refusal, with no appeal against the decision. There is a further, underappreciated incentive: where an audit of the APA application year or the two preceding periods results in a § 17(5) adjustment without abuse, § 18a(3) applies only the reduced supplementary-return-rate penalty of § 155(1)(g) — the ECB base rate per annum, minimum 3% — instead of the standard 10%-minimum assessment penalty.

Corresponding adjustments do not strictly require MAP. Under § 17(6) the Slovak administration may mirror a treaty partner's primary adjustment with the tax administrator's permission, and purely domestic downward adjustments are available subject to notification — mandatory for tax-relief claimants. MAP itself is governed by Act No. 11/2019 Coll., transposing the EU Dispute Resolution Directive and covering treaty MAP and the Arbitration Convention; the competent authority is the Ministry of Finance, and documentation must accompany the request (§ 18(13) ITA). Slovak law contains no secondary-adjustment mechanism — no deemed dividend follows a primary adjustment — and year-end adjustments are permitted but not compulsory. ETACA is available; Slovakia does not participate in ICAP.

Pillar Two and what changes in 2026

Slovakia implemented Pillar Two through Act No. 507/2023 Coll. on the top-up tax, effective 31 December 2023: a 15% qualified domestic minimum top-up tax on Slovak constituent entities of groups with consolidated revenues of at least EUR 750 million, with no IIR or UTPR (Slovakia uses the Directive's deferral for states with few parent entities). Amending Acts No. 355/2024 and 291/2025 folded in the OECD Administrative Guidance, a GIR-related notification and DAC9 exchange. For TP practitioners the point is interaction: primary and corresponding adjustments now move Slovak GloBE income, and top-up tax may be assessed for four periods.

The 2026 compliance reset is more immediate. Returns filed after 31 December 2025 use the DPPOv25 form and its granular Table I, and the October 2025 guideline abolishes abbreviated documentation for taxpayers who complete it properly. On Amount B, the OECD profile (May 2025) records the simplified and streamlined approach as under evaluation; nothing had been implemented as at August 2026, so Slovak distributors remain within the ordinary § 18 methods and the median rule — although Slovakia has committed to respect covered jurisdictions' Amount B outcomes.

How practitioners should respond

Three disciplines matter most. First, build benchmarking files that defend a point, not a range: the median default means an interquartile result is no longer a safe harbour, and the file must articulate why the taxpayer's specific outcome fits its functional profile. Second, treat Table I as the audit interface. Its 99 rows will be cross-checked against documentation and counterparty data, and inconsistency between the return, the local file and the accounting records is the cheapest audit trigger the administration owns. Documentation should be finalised by the filing deadline — the 15-day production window leaves no time to write it. Third, price certainty realistically. For material flows the APA fee — EUR 10,000, or half that for highly reliable taxpayers — buys not only method certainty but a statutory cut of any no-abuse audit penalty to the supplementary-return rate (ECB base rate, minimum 3% p.a.) across three periods, often worth more than the fee given the 10% minimum standard penalty and the abuse doubling. And where an assessment does land, the pay-and-forgo-appeal waiver of the § 18a doubling deserves a hard-headed cost-benefit review before litigating in a jurisdiction with little transfer pricing precedent.
