Montenegro’s Ministry of Finance has made clear that it does not intend to introduce personal income tax on winnings earned in casinos and slot-machine clubs, arguing that those segments of the gambling industry already operate under a heavier fiscal regime than betting, lottery games and global jackpot products. The position was presented in response to a constitutional initiative challenging the current tax treatment of gambling winnings, and it places the government’s gambling-tax policy back at the centre of a wider debate about fairness, fiscal design and competitive balance inside one of Montenegro’s most cash-sensitive regulated industries.
The key issue is not whether gambling should be taxed. It already is. The more difficult question is where the tax burden should fall: on the operator, on the player, or across both sides of the transaction. Under the current framework, winnings from betting games, lottery games and the global jackpot are taxed at 12 per cent, while winnings from casino games and slot machines are not taxed in the same way. Critics argue that this creates unequal treatment inside the same regulated market. The Ministry of Finance argues that the comparison is incomplete because casino and slot operators face higher licence fees, guarantees and variable charges than betting operators.
According to the Ministry’s explanation, casino operators are subject to the strictest fiscal regime. A casino organiser must pay a one-off approval fee of €2 million, provide an unconditional bank guarantee of €400,000, pay an annual fixed fee of €100,000, and pay a variable fee of 15 per cent of gross gaming revenue. Slot-machine clubs also pay a fixed fee per machine and a variable fee of 15 per cent of gross revenue, while betting operators pay a one-off approval fee, annual fixed fees and a variable charge of 10 per cent of gross revenue.
That fiscal architecture is the Ministry’s central argument. In its view, the existence of a 12 per cent personal income tax on some winnings cannot be examined in isolation from the total fiscal burden imposed on each category of gambling operator. The Ministry is effectively saying that Montenegro’s gambling system is not designed around one uniform tax applied equally to all game types, but around differentiated fiscal models depending on the structure, risk profile and revenue mechanics of each segment.
The legal dispute was triggered by the non-governmental association of companies organising games of chance, “Crna Gora klađenje”, through a constitutional initiative submitted by lawyer Boris Zvicer. The initiative challenges the provision that taxes winnings from betting, lottery games and the global jackpot while excluding casino and slot-machine winnings from the same personal income tax treatment. The argument is that such differentiation places betting and lottery organisers in a less favourable position compared with casino and slot operators, even though all operate within the same broad gambling sector.
The Ministry rejects that logic. In its response, signed by Finance Minister Novica Vuković, it stated that there is no basis to accept the initiative and that Montenegro’s Constitution gives the legislator broad discretion in designing the tax system. The Constitution does not prescribe which types of income must be taxed or at what rate. That leaves the state with room to decide which tax solution is economically appropriate, fiscally necessary or socially justified.
The Ministry’s second argument is technical but important: the taxpayer under the challenged provision is not the gambling company, but the physical person who wins. The organiser has an obligation to calculate, withhold and pay the tax at source, but the legal tax burden belongs to the winner. From the Ministry’s perspective, the provision does not regulate taxation of gambling companies and therefore does not directly change their tax position as corporate entities. It regulates the income of individuals who win in certain types of games.
That distinction matters legally, but it may not fully settle the economic question. Even when a tax is formally imposed on the player, it can still affect the operator’s market position. Players respond to net winnings, not only to gross payouts. If one type of game produces taxable winnings and another does not, consumer behaviour can shift. Betting companies argue that players may naturally prefer casino and slot-machine games if winnings there are not subject to the same deduction. In a competitive market, the legal incidence of tax and the commercial effect of tax are not always the same thing.
This is where the policy becomes more complex. Montenegro’s gambling industry is not a single uniform business. Casinos, slot clubs, sports betting, lottery games and jackpot systems have different capital requirements, margins, risk structures, monitoring needs and social impacts. A casino licence involves a high entry fee, physical premises, supervision, table games, staff, anti-money-laundering controls and a different customer profile. Betting operations depend on odds, digital channels, shop networks, payment flows and high transaction volume. Slot-machine clubs sit somewhere between physical gambling infrastructure and high-frequency machine revenue.
The Ministry’s position reflects this segmentation. A casino operator paying €2 million to obtain approval, maintaining a €400,000 unconditional bank guarantee and paying 15 per cent of gross gaming revenue is in a different fiscal category from an operator with a lower variable rate of 10 per cent. The state is arguing that higher operator-side charges justify the absence of player-side income tax on casino and slot-machine winnings.
Yet the challenge from the betting sector points to a real commercial sensitivity. Tax treatment shapes market incentives. A 12 per cent withholding tax on winnings may appear moderate, but in gambling it can influence player perception, especially where winnings are frequent and visible. For casual players, the difference between taxed and untaxed winnings can become part of the choice between products. For operators, it affects marketing, customer retention and payout psychology.
The policy history also shows how unsettled Montenegro’s gambling-tax framework has become. Over the past year and a half, the personal income tax rules for gambling winnings have reportedly changed three times. At one stage, all types of games of chance were taxed, with winnings up to €300 exempt and amounts above that taxed at 15 per cent. The system was then changed so that winnings from betting, lottery and the global jackpot up to €50 were tax-free, with a 10 per cent rate applied up to €1,500 and 15 per cent above that threshold. In May, the framework was changed again, with every winning from those three categories taxed at 12 per cent.
That sequence is important because frequent tax changes create uncertainty for both operators and players. Gambling companies need stable rules to price products, manage systems, advertise responsibly and calculate compliance obligations. Players need clarity on what they actually receive. The state needs a tax system that can be administered without constant reinterpretation. Three changes in roughly 18 months suggest that Montenegro is still searching for the right balance between revenue collection, market fairness and political acceptability.
The fiscal stakes are not negligible. Gambling has become a more visible source of public revenue in Montenegro, particularly as the government looks for ways to broaden revenue without placing additional pressure on more traditional parts of the economy. Betting shops, digital betting, slot clubs and casinos represent a sector where cash flows are measurable, regulated and politically easier to tax than salaries or basic consumption. But the same sector is also socially sensitive, with risks linked to addiction, household finances, informal money flows and anti-money-laundering supervision.
That makes the design of gambling taxation more than a budget question. A good system should raise revenue, preserve legal certainty, avoid distorting competition too sharply and support responsible oversight. A poorly designed system can push players toward less regulated channels, encourage product substitution, create disputes between operator groups and weaken trust in the tax framework.
Montenegro’s current dispute shows the difficulty of taxing a mixed gambling market. A uniform player tax across all games may look fair at first glance, but it could ignore the heavier licensing burden on casinos and slot-machine clubs. A differentiated system may reflect different business models, but it can also create perceptions of unequal treatment. The correct answer depends on the total fiscal burden, market behaviour, revenue outcomes and regulatory objectives.
For the Ministry of Finance, the constitutional argument is straightforward: there is no discrimination because the tax applies to individual winnings, not to the operator’s income, and because different gambling segments are already subject to different fiscal models under the Law on Games of Chance. In this reading, the state has the right to structure taxes and fees according to the nature of the game and the policy objective being pursued.
For betting operators, the commercial concern is equally clear. They are required to withhold tax on player winnings in their segment, while casinos and slot-machine clubs can offer untaxed winnings to players. Even if operators are not formally the taxpayers, they still manage the customer relationship and may carry the competitive consequences. That is why the dispute cannot be reduced only to legal form. It is also about market incentives.
The broader question is whether Montenegro wants a gambling-tax system based primarily on operator licensing and gross revenue, or one that increasingly captures player winnings. Casino taxation is already front-loaded and operator-heavy. Betting taxation now includes a clear player-income component. The coexistence of these models may be defensible, but it needs a clear policy explanation if it is to avoid repeated constitutional and business-sector challenges.
There is also an administrative dimension. Withholding tax on betting and lottery winnings requires systems that can identify winnings, calculate tax, deduct it and transfer it to the state. This is easier in some digital and ticket-based betting formats than in casino environments where play may involve chips, tables, machines, cash-ins, cash-outs and session-based activity. Taxing casino winnings at player level could require a more complex tracking and reporting system, especially for smaller or repeated wins. The Ministry’s preference for heavy operator-side taxation in casinos may therefore reflect practical enforceability, not only fiscal philosophy.
Still, the government will need to manage perception. A headline that casino and slot-machine winnings remain untaxed while betting winnings are taxed at 12 per cent can easily be read by the public as preferential treatment, even if the underlying fiscal regime is more complex. In tax policy, perception matters because it affects compliance and political legitimacy. The state needs to explain why one segment pays through licence fees and gross-revenue charges while another also withholds player income tax.
The issue also intersects with Montenegro’s wider public-finance debate. The government is under pressure to increase revenue, maintain social spending, support infrastructure needs and keep the business environment competitive. Gambling taxation offers a tempting revenue source, but repeated changes can create instability. A mature tax framework should be predictable enough for operators, transparent enough for citizens and flexible enough for regulators to control risk.
The latest position from the Ministry suggests that, at least for now, Montenegro will keep the differentiated model. Casino and slot-machine winnings will remain outside the 12 per cent personal income tax applied to betting, lottery and global jackpot winnings. Casino operators will continue to be taxed through high entry costs, guarantees, fixed fees and a 15 per cent gross-revenue charge. Betting operators will continue to operate with a lower gross-revenue charge but with player winnings taxed at source.
That may be legally defensible, but the policy debate is unlikely to disappear. The gambling market is too visible, too profitable and too politically sensitive for tax asymmetries to pass without challenge. The state will need to demonstrate that the total burden across different game types is proportionate and that the rules do not artificially redirect players from one segment to another.
For Montenegro, the most important objective should be a stable and coherent gambling-tax system rather than another round of short-term amendments. Operators need predictability. Players need transparency. The state needs revenue and control. A system that changes repeatedly risks achieving less of all three. The Ministry’s refusal to extend personal income tax to casino and slot-machine winnings clarifies the government’s current position, but it also exposes the deeper policy task: building a gambling-tax framework that can withstand legal challenge, market pressure and fiscal expectations without being rewritten every few months.
