Denmark Public-Private Partnership Tax Guide

Types of PPP Arrangements in Denmark

• OPP (Offentligt-Privat Partnerskab): A long-term contractual arrangement where a private partner designs, builds, finances, operates, and maintains public infrastructure (e.g., schools, hospitals, roads). The public partner pays a periodic service fee (ydelsesbetaling) over the contract term (typically 20-30 years). At contract end, the asset is transferred to the public partner.
• KPP (Koncessionsprojekt): A concession-based PPP where the private partner finances, builds, and operates an asset, recovering its investment through user charges (e.g., toll roads, bridges, parking facilities). The private partner bears demand risk. Examples include the Øresund Bridge and the Storebælt Bridge (though these are state-owned enterprises, the model applies).
• Lease/lease-back arrangements: The public partner leases an asset to a private partner who leases it back, often used for energy efficiency upgrades (ESCO contracts). These raise specific VAT and corporation tax issues regarding the lease payments.
• Service concessions: The private partner provides specific public services (e.g., prison management, IT services) under a long-term contract without significant infrastructure investment. Treated primarily as service contracts for tax purposes.

VAT on PPP Contracts

VAT is the most complex issue in Danish PPP arrangements because public authorities are generally not VAT-registered:

• Public authority VAT exemption: Danish municipalities and regions (kommuner/regioner) are generally non-VAT-registered entities under ML §3. They cannot deduct input VAT on their purchases. This creates a structural VAT cost in PPP arrangements — the VAT on construction and operating costs becomes a real cost for the public partner.
• Compensatory VAT grant (kompensation for momseffekt): Municipalities receive a state budget grant to compensate for non-deductible VAT on outsourced services (refusionsordningen). The grant covers the VAT amount, effectively making the municipality's VAT cost neutral. However, the grant is capped and may not fully cover large PPP projects, creating a budget risk.
• Reverse charge on construction services: For certain PPP construction services, the reverse charge mechanism may apply, shifting VAT liability from the foreign contractor to the Danish recipient. This is relevant where international consortia are involved in Danish PPP projects.
• Mixed supplies (service vs lease): The periodic service fee in an OPP contract may contain both service and financing elements. SKAT may recharacterise the fee if it considers the arrangement a financial lease rather than a service contract, potentially changing the VAT treatment. Proper contractual structuring is essential to avoid unexpected VAT assessments.
• VAT grouping for PPP SPVs: PPP special-purpose vehicles (SPVs) can join VAT groups with subcontractors if the 100% ownership requirement is met. This can eliminate VAT on intra-group supplies and simplify compliance, though the 3-year minimum commitment applies. For details, see our VAT Groups Guide →.
• Transition at contract end: When the asset transfers back to the public partner at contract end, no VAT is due on the transfer itself (it is not a taxable supply). However, any remaining input VAT adjustments (ML §9, korrektion af fradrag) may be triggered.

Corporate Tax Considerations

• PPP SPV taxation: The private partner typically establishes a Danish special-purpose vehicle (SPV) — usually an ApS or A/S — which is subject to standard 22% corporate tax. The SPV's taxable income is: service fees received, minus operating costs, financing costs, and tax depreciation on the PPP asset.
• Tax depreciation of PPP assets: The SPV can claim tax depreciation (skattemæssige afskrivninger) on the PPP asset under standard rules. Buildings depreciate at 4% straight-line (or accelerated rates if qualifying). Equipment/operating assets depreciate under the declining-balance method at up to 25% annually. Goodwill arising from the PPP contract may be amortised over 7 years.
• Financing structure: Interest on third-party debt financing the PPP is deductible under standard thin capitalisation rules (SEL §11 C). The safe harbour of 4% EBITDA may limit interest deductions if the SPV is highly leveraged. Shareholder loans must meet arm's-length criteria. Cross-border financing introduces withholding tax at 22% (reduced under treaties).
• Tax-exempt government grants: Grants received from Danish public authorities for PPP projects are generally taxable as income (they are not tax-exempt gifts). However, grants specifically designated as capital contributions (tilskud til anlægsinvesteringer) may be treated as a reduction of the asset's cost base rather than income, reducing depreciation deductions over time.
• Loss utilisation: PPP SPVs often have early-year losses and later-year profits. Losses can be carried forward indefinitely (subject to the ownership change limitation — losses forfeited if >50% ownership changes and the business purpose shifts). Group relief (sambeskatning) allows current-year loss transfer within a Danish joint taxation group.

Withholding Tax and Cross-Border Issues

• Payments to foreign consortium members: International PPP consortia often include foreign partners. Service fees, management fees, and interest paid to non-Danish group companies are subject to 22% withholding tax unless reduced under an applicable tax treaty.
• Construction site permanent establishment: Foreign construction companies working on Danish PPP projects for more than 30 days (or 3 months depending on the treaty) risk creating a permanent establishment (PE) in Denmark, triggering Danish corporate tax on profits attributable to the PE.
• Withholding tax exemption for qualifying interest: Interest on certain Eurobond-type financing may be exempt from Danish withholding tax under SEL §11 D if certain conditions are met (listed on a recognised exchange, arm's-length terms). This exemption is commonly used for large PPP financings.
• Dividends from PPP SPV: Dividends distributed by the Danish PPP SPV to its foreign parent are subject to 22% Danish withholding tax, reduced to 0% (if ≥10% ownership, 12-month holding) under the participation exemption or to a reduced treaty rate. Ensure the parent qualifies for the exemption before distributing.

Procurement Law Interaction with Tax

• Danish Public Procurement Act (Udbudsloven): PPP contracts above EU thresholds (~40 million DKK for works, ~5.6 million DKK for services) must follow EU procurement procedures. The tender documentation should specify the tax regime applicable to the contract, including VAT treatment.
• Tax as a selection criterion: Under Danish procurement rules, a bidder's tax compliance history can be used as a qualitative selection criterion (udelukkelsesgrund). Bidders with unpaid tax debts exceeding 50,000 DKK at the deadline may be excluded from the tender process.
• Most economically advantageous tender (MEAT): PPP contracts are awarded based on the most economically advantageous tender (bedste forhold mellem pris og kvalitet), not just lowest price. Tax structuring that reduces the total cost to the public authority (e.g., through efficient VAT structuring) is a legitimate element of the price evaluation.
• Contract modification rules: Significant changes to PPP contracts (including tax-driven restructurings) during the contract term may trigger a new procurement obligation under EU case law (e.g., the Pressetext Nachrichtenagentur principle). Any tax-driven restructuring of the PPP SPV should be reviewed for procurement compliance.

Key Risks and Mitigations

• VAT risk: The most significant risk in Danish PPPs is unexpected VAT liability. Engage a VAT specialist early. Consider obtaining a binding ruling (bindende svar) from SKAT on the VAT treatment before signing the contract.
• Permenent establishment risk: Foreign construction companies should carefully monitor days on site and consider structuring through a Danish sub-subsidiary to avoid PE creation.
• Transfer pricing: All intra-group transactions in the PPP structure (management fees, financing, subcontractor margins) must be at arm's length. SKAT has a PPP task force that reviews transfer pricing arrangements.
• Change in law: PPP contracts should include a change-in-law clause allocating the risk of adverse tax law changes between the public and private partners. Standard Danish OPP contracts (developed by Kombit and the Danish Competition Authority) include such clauses.
