Montenegro has already taken the legislative step that introduces common market rules in practice. In July 2026, its parliament adopted a substantial overhaul of the Corporate Income Tax Law, introducing European rules on interest deductions, controlled foreign companies, exit taxation, hybrid arrangements and artificial tax structures.
The amendments were published in the Official Gazette on 17 July 2026 and the domestic provisions are scheduled to apply from 1 January 2027. The most important cross-border anti-avoidance measures, however, will take effect only when Montenegro joins the European Union.
This places Montenegro in a similar legal position to Serbia, but with a potentially shorter transition. The EU has begun preparatory work on Montenegro’s accession treaty, while Podgorica is targeting membership by 2028.
The law is frequently described as a mechanism for stopping foreign investors from taking profits out of the country without paying tax. That description captures only part of the reform. Montenegro is not imposing capital controls and will not prevent foreign owners from repatriating legally earned dividends, interest or sale proceeds. The legislation instead changes the tax treatment of transactions used to relocate taxable income, assets or financing expenses between related companies.
The distinction matters for a country unusually dependent on foreign capital. Preliminary data indicate that Montenegro received more than €1 billion of gross foreign direct investment in 2025, while net inflows reached approximately €530 million. Real estate accounted for around €497 million, investment in companies and banks for roughly €132 million, and intercompany lending for about €319 million.
That composition explains why the new rules matter beyond conventional tax administration. A large proportion of foreign capital enters Montenegro either through property acquisition or loans between affiliated companies. Intercompany debt is frequently used to finance hotels, residential developments, energy assets, holding companies and operating subsidiaries. The interest paid on those loans can reduce taxable profit in Montenegro while generating income for a parent, shareholder or financing company abroad.
Montenegro’s reform directly targets that channel.
Under the new interest-limitation rule, net borrowing costs will be deductible only up to 30 per cent of tax-adjusted EBITDA or €3 million, whichever is higher. The €3 million allowance applies at group level rather than separately to every company within the same structure. Financing expenses exceeding the limit will increase taxable income, although disallowed costs may be carried forward for three subsequent tax periods.
The definition of borrowing costs is broad. It encompasses conventional interest, financing elements within leases, capitalised interest, guarantee fees, economically equivalent charges, certain foreign-exchange movements and expenses associated with raising finance. The rule is designed to examine the economic substance of financing rather than merely the title used in the underlying contract.
Standalone companies that are not members of a consolidated group, do not have associated enterprises or permanent establishments, and do not lend to or borrow from shareholders may fall outside the restriction. Regulated financial companies are also excluded. Certain long-term public infrastructure projects can receive separate treatment where the project, financing, assets and income satisfy the prescribed EU conditions.
The effect will be concentrated among multinational and highly leveraged groups. Montenegro’s tourism and property market has attracted projects built through layered special-purpose vehicles, shareholder loans and offshore holding structures. Similar models are used in renewable energy, telecommunications, marina development, retail centres and acquisition finance.
Consider a hotel development company generating €4 million of EBITDA and incurring €2 million of net borrowing costs. The EBITDA-based threshold would ordinarily allow a deduction of €1.2 million, but the statutory €3 million threshold would be more favourable, leaving the full interest amount potentially deductible. The rule is therefore unlikely to constrain many smaller Montenegrin businesses.
The picture changes at group level. A large resort, infrastructure or energy portfolio with €20 million of EBITDA and €10 million of net financing costs would face a standard deduction ceiling of €6 million. The remaining €4 million would initially increase the taxable base and could be carried forward subject to future capacity.
At Montenegro’s top corporate tax rate, the immediate tax effect could reach approximately €600,000, before any use of carried-forward amounts. That changes project cash flow, debt-service coverage and the relative attractiveness of shareholder debt compared with equity.
Montenegro no longer has the single 9 per cent corporate tax rate with which it was identified for many years. Its progressive system taxes the first €100,000 of profit at 9 per cent. Profit between €100,000 and €1.5 million is subject to a formula equivalent to €9,000 plus 12 per cent of the amount above €100,000. Taxable profit exceeding €1.5 million attracts €177,000 plus 15 per cent of the excess.
Most substantial foreign-owned businesses therefore face a marginal corporate rate of 15 per cent, bringing their effective exposure closer to Serbia’s flat 15 per cent regime. The attraction of Montenegro increasingly rests on its euro-based economy, small market, tourism assets, relatively accessible company formation and prospective EU membership rather than on a uniformly low corporate tax rate.
The second major pillar is the controlled foreign company regime. A foreign entity or permanent establishment may be treated as a CFC where a Montenegrin taxpayer, alone or together with associated parties, controls more than 50 per cent of voting rights, capital or profit entitlement and the foreign entity is subject to substantially lower taxation.
Certain undistributed profits would then be included in the Montenegrin parent company’s tax base. The covered categories include interest and other financial income, royalties, dividends, gains from shares, financial leasing, insurance and banking income, and related-party sales or services that create little genuine economic value.
The legislation preserves an exemption for foreign companies conducting substantial economic activity supported by real employees, equipment, assets and premises. A foreign subsidiary running an operating hotel, industrial facility, technology business or trading platform should therefore be distinguishable from a shell company holding intellectual property, loans or passive income without meaningful local operations.
For Montenegrin groups expanding into low-tax jurisdictions, documentation will become as important as ownership structure. Management must be able to show where commercial decisions are made, where employees work, which entity bears contractual risks and where the underlying value is created.
A further measure introduces exit taxation. Montenegro will tax the difference between an asset’s market value and its tax value when the country loses the right to tax that asset because it has been transferred abroad. The rule also covers transfers of tax residence and businesses operated through permanent establishments.
The measure is particularly relevant to holding companies, intellectual property, development rights and assets whose value has increased while located within Montenegro. A company will no longer be able to move an appreciated asset or business function to another jurisdiction and leave the embedded gain outside Montenegro’s tax base simply because no conventional sale has occurred.
Where assets are transferred to an EU member state or qualifying European Economic Area jurisdiction, the resulting liability may be spread across five tax periods, subject to an appropriate guarantee and interest. Temporary transfers lasting no more than 12 months may be excluded in specified circumstances, including securities financing, collateral, regulatory capital and liquidity management.
This is more than an accounting adjustment. Exit tax can create a material cash liability during a corporate restructuring even though the taxpayer has not received sale proceeds. Investors contemplating relocation of intellectual property, migration of tax residence or consolidation of regional assets will need valuations and liquidity planning before executing the transaction.
Montenegro is also introducing rules against hybrid mismatches. These address arrangements that receive different legal or tax treatment in two jurisdictions, allowing the same expense to be deducted twice or an expense to be deducted in one country without the corresponding income being taxed in another.
Such structures can arise from hybrid financial instruments, entities classified differently by two tax systems, or payments between a head office and permanent establishment. The Montenegrin rules can deny the deduction, require the income to be included in the tax base or restrict withholding-tax benefits.
The legislation adds a general anti-abuse rule with potentially wider importance than any individual technical provision. Tax exemptions, reductions and treaty benefits may be denied where an arrangement was established to obtain a tax advantage and lacks significant commercial reasons reflecting economic reality.
This gives the Tax Administration a legal basis to look through formally compliant structures. A holding company, loan, royalty arrangement or restructuring may satisfy the wording of a specific provision and still lose the intended benefit where the commercial rationale, decision-making and operational substance cannot be demonstrated.
The reform nevertheless contains substantial benefits for genuine EU corporate groups. Once Montenegro becomes a member, dividends paid by a Montenegrin subsidiary to a parent company in another EU state will be exempt from withholding tax where the parent holds at least 10 per cent of the subsidiary continuously for 24 months and meets the required legal-form, tax-residence and corporate-tax conditions.
Dividends received by a qualifying Montenegrin parent from an EU subsidiary would similarly be excluded from the Montenegrin tax base, provided the payment is not treated as a deductible expense by the subsidiary. Anti-abuse provisions would deny the exemption where the arrangement was established for tax evasion or avoidance.
Interest and royalty payments between associated companies in Montenegro and the EU would also become exempt from withholding tax when the required relationship is maintained for at least 24 months. The relevant ownership threshold is generally 25 per cent, whether one company holds the other or a common parent owns the prescribed interest in both.
The recipient must be the beneficial owner, not an agent or intermediary, and it must provide the necessary tax-residence certification. Profit-participating loans, instruments convertible into profit rights, debt without a genuine repayment obligation and exceptionally long-dated arrangements may be excluded from the relief.
This creates a two-directional change. Montenegro will become stricter towards excessive debt, shell companies, artificial asset transfers and hybrid structures, but more accommodating towards genuine dividends, interest, royalties and reorganisations within qualifying EU groups.
The existing regime remains relevant until accession. Montenegro currently applies a standard 15 per cent withholding tax to dividends and profit distributions paid to resident and non-resident legal entities, as well as to various interest, royalty, rental, consulting, market-research and audit payments to non-residents. Double-tax treaties may reduce or eliminate the charge when their conditions are satisfied.
Payments to entities in preferential or non-transparent jurisdictions can attract withholding tax of 30 per cent. Montenegro’s domestic law also requires transfer prices between related parties to reflect arm’s-length conditions.
Large taxpayers must submit transfer-pricing documentation with their corporate tax returns. Other companies must hold the documentation and provide it to the Tax Administration within 45 days of a request. A simplified format is available where related-party transactions remain below €75,000 in the relevant year.
Consequently, Montenegro is not waiting for EU membership before policing all profit transfers. Existing withholding-tax, treaty, beneficial-ownership and transfer-pricing rules already allow the authorities to challenge excessive interest, unsupported management fees, artificial royalties and transactions priced outside market conditions.
The reform strengthens that framework and adds mechanisms that depend on reciprocal EU cooperation. It also introduces advance pricing agreements, under which taxpayers and tax authorities can agree transfer-pricing methodologies before or during the relevant transactions. For large tourism, infrastructure, energy and telecommunications groups, an APA could reduce future disputes where cross-border services, financing and intellectual-property charges are material.
The comparison with Serbia reveals a similar technical direction but a different investment setting. Both countries are moving towards a 30 per cent EBITDA interest ceiling, a €3 million safe threshold, CFC rules and EU-compatible treatment of qualifying dividends, interest and royalties. Both link their central anti-avoidance chapters to formal EU accession.
Serbia’s larger manufacturing base means its reform will reach export plants, automotive suppliers, mining, energy and leveraged industrial groups. Montenegro’s exposure is more concentrated in property, tourism, hospitality, energy, banking and shareholder-financed development companies. Intercompany debt is particularly important because it represented approximately €319 million of Montenegro’s FDI inflow in 2025.
Montenegro’s possible 2028 accession also gives the transition greater immediacy. Investors financing a hotel, marina, wind farm, solar portfolio or residential resort today may still be operating under the same loan structure when the EU-linked provisions enter into effect. A five- or seven-year project model that assumes unrestricted interest deductibility and current withholding-tax treatment could therefore become inaccurate during the investment period.
Debt-service models should test the loss of interest deductions under the 30 per cent EBITDA rule, particularly during ramp-up years. Shareholder loans require market-rate benchmarking and a genuine repayment profile. Holding structures need to satisfy beneficial-ownership and economic-substance tests. Planned transfers of development rights, intellectual property or tax residence should include exit-tax valuations. Dividend models must distinguish current treaty treatment from the future EU exemption.
The new rules do not make Montenegro hostile to foreign capital. They make the distinction between capital invested in operating activity and structures designed mainly to move taxable income much sharper. Foreign shareholders will remain able to repatriate profits, but the legal route, economic substance and tax evidence behind each payment will carry considerably more weight.
Montenegro’s tax proposition is moving closer to the model of a small EU economy: progressive corporate tax of up to 15 per cent, tighter control of related-party financing, withholding relief for qualifying European groups and increasingly limited tolerance for structures lacking real people, assets and commercial purpose. For investors entering the market before accession, the central risk is no longer simply the current tax rate. It is whether the financing and ownership structure designed today will still produce the expected cash flows once Montenegro becomes part of the EU tax system.
