Peru, Mexico and Argentina – Mexico Doubled Its Gambling Tax for Nothing

Peru, Mexico and Argentina – Mexico Doubled Its Gambling Tax for Nothing

Mexico collected MXN 2,025m in gambling IEPS in H1 2026 against a MXN 2,513m target – −0.2% in real terms year on year. The rate had just doubled to 50%. We read Peru and Argentina over the same six months as the control group, and the divergence is stark.

Key Takeaways

• Mexico's gambling IEPS doubled to 50% and receipts fell 0.2% in real terms.
• Caliente's share dropped from 40.2% in December 2025 to 21.8% by March.
• Peru charges 1% on deposits and blocked 36 platforms in July.
• Argentina's July betting-tax receipts rose 50.5% year on year.
• Buenos Aires Province estimates 80% of online betting stays unregistered.

Mexico ran the natural experiment nobody wanted

The Paquete Económico 2026 raised IEPS on juegos con apuestas y sorteos from 30% to 50%, effective 1 January 2026, covering land-based and digital operators and applying to residents and non-residents alike. The Senate passed it over industry objection. Six months later we have the cleanest tax-elasticity test the region has produced.

H1 2026 IEPS from games and lotteries came in at MXN 2,025m against a Treasury target of MXN 2,513m – a shortfall of MXN 487.6m. The comparable H1 2025 figure was MXN 1,952m. That is +3.7% in nominal pesos and −0.2% in real terms, in a half-year that also brought digital casinos into the IEPS net for the first time and included a co-hosted FIFA World Cup. El Universal attributes the miss to US measures against cartels linked to gaming, tighter real-time SAT monitoring, and digital-casino betting simply failing to rise.

Lotería Nacional carries a 40% fiscal stimulus against the same IEPS, so the state lottery is materially insulated from the rate imposed on private operators. Milenio reported pre-enactment analyst warnings that the SAT could lose up to MXN 12bn (~USD 650m) to contraction and offshore migration. H1 2026 is consistent with the direction, if not the magnitude.

Why the damage landed on licensed operators

The aggregate revenue number hides the more important finding. Mexico's iGaming activity index fell 35% from its December 2025 peak in the first two months of 2026, ending a four-year uptrend that had delivered +42.4% in 2023, +59% in 2024 and +52.9% in 2025. March brought a partial rebound of +4% against February. The decline was not evenly shared across the market.

Locally licensed brands lost 34% of index value. International brands lost under 7%. Caliente fell from 40.2% share in December 2025 to 21.8% in March 2026; bet365 had already slid from 24.3% in January 2022 to 3.2% by December 2025. A punitive GGR tax applied to licensed operators, with a functioning offshore alternative one click away, moves share to the untaxed layer instead of closing it. That is the same mechanism we documented when Colombia's deposit-tax decree cut regulated GGR by roughly 30%, and Mexico is repeating the lesson at a larger scale.

Mexico's structural problem sits underneath the tax. The market still runs on the 1947 Ley Federal de Juegos y Sorteos, administered by SEGOB through a small set of master permits – so new entrants typically launch under a permit holder's umbrella. Trade compilations count 38 authorised permit holders, 430+ venues, 120+ legal online operators and 30+ digital operators on .mx domains as of September 2025. AIEJA estimates 60% of bookmakers operating in Mexico in 2024 lacked a SEGOB licence, with the illegal online market at roughly USD 450m. Our breakdown of how gambling licences actually work covers why permit structures behave differently from direct licences.

The 2023 slot decree makes it worse. The DOF decree of 16 November 2023 stopped new slot-machine permits, shortened permit durations and abolished the operador figure. At least 12 operators and permit companies filed amparos; several district courts granted injunctions. Mexican floors now run on a patchwork – slots operate where injunctions hold and are banned where they do not. The SCJN postponed a key vote on 16 July 2026, and in August the plaintiff withdrew its amparo, removing the vehicle entirely. The decree's constitutionality is unresolved going into 2027. SEGOB's wider reform bill, announced for early 2026 with a proposed Instituto Nacional de Juegos y Sorteos, has not passed.

Peru took the opposite bet and it is working

Peru licenses nationally under Law 31557 and DS 005-2023-MINCETUR, live since 10 February 2024, with a single regulator in MINCETUR's DGJCMT. By mid-2026 it reported more than 90 authorisations for remote gaming and remote sports betting – 92 on the latest count – plus 4,534 points of attention. Authorisations run 6 calendar years, renewable, and MINCETUR reports holders to UIF-Perú and SUNAT.

The tax design is the deliberate opposite of Mexico's. ISC on remote gaming sat at 0.3% per bet until 30 June 2025 and rose to 1% from 1 July 2025, with a levy on gross gaming revenue reported at 12% alongside it. Critically, the ISC base is the amount wagered or deposited, not GGR, so Peru's headline rate is not directly comparable to Mexico's 50%. Collection tells the story: S/419m (~USD 115m) for full-year 2025, and S/334m (~USD 91m) in January–May 2026 alone – five months already at about 80% of the previous full year.

That pre-registration is the quiet lever. Because the regulator holds the authoritative domain register, the MTC-executed ISP blocklist becomes mechanical: anything not on the register is by definition blockable. On 21 July 2026 MINCETUR blocked 36 technological platforms serving Peruvian users without authorisation, seized 39 clandestine slot machines across four premises in Lima, Lambayeque and Piura, and reported cumulative closures of 14 sports-betting premises and 6 slot halls – 20 premises in total. Promoting illegal gambling carries 1 to 4 years' imprisonment on top of administrative sanctions.

Peru also bans cryptocurrency outright for licensed operators. Article 38.d requires stakes and prizes to move through legal tender, cards or bank rails. We track the contrast in our work on how crypto payments are being absorbed by regulated casino markets.

No regulator publishes a Peru channelisation rate, so the 36-platform block remains the only hard proxy for the size of the unlicensed layer. Operators are already contesting the ISC design, arguing a deposit levy stacked on a GGR tax erodes competitiveness against offshore.

Argentina: 24 regulators, no national law, record receipts

Gambling in Argentina is a non-delegated provincial competency. There is no national gambling law, only 24 separate regulators – 23 provinces plus CABA. On the better-dated June 2026 count, 20 of 24 jurisdictions have an operational regulated online market, with Tierra del Fuego, Salta, Santiago del Estero and San Juan outside it – though sources disagree, and a competing account puts 23 of 24 already regulated. San Juan passed its law in December 2024 but the regulations remain incomplete with no operative licences.

Supply is deliberately constrained where the money is. LOTBA in CABA has closed its licence round and is not open to new entrants, with permits running 5 years and extendable once by 5. IPLyC in Buenos Aires Province holds a statutory cap of 7 licences on 15-year non-extendable terms. A licence is valid only inside its issuing jurisdiction, so a CABA-licensed operator cannot lawfully accept a bet from a player physically in BA Province.

The tax burden stacks: IVA at 21%, a national indirect tax on online bets of 2.5%–15% depending on the operator's legalisation status, corporate income tax at 35%, dividend withholding at 7%, a player prize tax of 30% on 90% of winnings, plus provincial ingresos brutos – 10% in Córdoba, 5% in Mendoza, 2% per winning bet in Buenos Aires. That differential rate prices legalisation status directly rather than taxing everyone flat.

Receipts responded. July 2026 online betting tax revenue rose 27.8% in real terms month on month and 50.5% year on year – the largest monthly variation on record – with January–July cumulative growth at +40%. The World Cup period drew 4.6 million active users, with the online segment estimated above USD 1.5bn. The sector is put at over 2% of Argentine GDP, growing 20–35% annually since 2021.

Enforcement is catching up. Less than 48 hours before the World Cup final, on 17 July 2026, the San Isidro cybercrime prosecutor working with IPLyC ordered 537 illegal betting sites blocked – the largest mass block ever carried out in the province – after a prior round of 251 sites in April. The stated grounds were operating outside the framework, lacking certifications guaranteeing game randomness, and allowing minors to register. On advertising, the Chamber of Deputies approved a dictamen 134 votes to 32 for broad national restrictions, but a competing Executive bill in the Senate targets blocking and problem gambling instead. The advertising text entered the Senate in October 2025 and has not left committee. The harm data driving the politics is stark: 1 in 3 adolescents admitted wagering online at least once, and 47% knew of betting platforms.

Three models, side by side

The three markets sit at different points on the same curve. Peru taxes lightly and enforces administratively. Argentina taxes heavily but fragments authority across 24 desks. Mexico taxes hardest and has published no enforcement count at all.

For regional scale, Brazil's first regulated year delivered USD 4.5bn against USD 2.8bn for LatAm excluding Brazil, and the region is growing at roughly 30% year on year. That licensed Brazilian market no longer exists – a September 2026 provisional measure banned fixed-odds betting outright, which puts the political risk on every LatAm licence in a new light. At the other end, Chile's online betting bill is still stuck in the legislature, which is where Argentina's four holdout provinces effectively sit too. We have set these tax models against European precedent in our comparison of LatAm and European regulated markets.

What we are watching

The next six months decide whether Mexico's rate is a one-year stumble or a structural error, and whether Argentina's blocking rounds harden into policy. These are the specific prints we are waiting on.

• Mexico's H2 2026 IEPS print, due February 2027. A flat or negative full year after a World Cup makes the 50% rate empirically self-defeating.
• The SCJN and the 2023 slot decree. With the amparo withdrawn in August, the court needs a new vehicle. Until then, floors run on injunctions.
• Mexico's blocking output. The powers exist on paper. No published count of blocked domains exists yet, and the first real number is a story either way.
• Peru's ISC debate. Operators are pushing back on stacking a deposit levy on a GGR tax. Watch the 2027 budget for a rate or base change.
• Argentina's advertising bill versus the Executive's blocking bill. Two conflicting texts, neither moving. A post-World-Cup harm backlash is the likeliest unlock.
• Argentina's blocking cadence. 251 sites in April and 537 in July; a third round makes it policy rather than an event.
• San Juan's regulations. The law passed in December 2024 but no operative licences exist yet. It is the next province likely to open.

FAQ

Is online gambling legal in Peru?

Yes. Peru regulates remote gaming and remote sports betting under Law 31557 and DS 005-2023-MINCETUR, in force since February 2024. More than 90 authorisations were live in mid-2026. Authorised operators must register their exact domain with MINCETUR before launch, and unregistered platforms are blocked by the MTC – 36 of them in July 2026 alone.

Are the Mexican and Argentine online markets legal?

Both are, but the structures differ. Mexico operates under a 1947 federal law, with SEGOB issuing a limited number of master permits that most online brands operate beneath. Argentina has no national gambling law at all: 24 provincial and city regulators license separately, and 20 of the 24 jurisdictions currently have an operational regulated online market. A licence only covers players physically inside its issuing jurisdiction.

Why did Mexico's tax increase collect less money?

The rate rose from 30% to 50% on 1 January 2026, but the taxed base shrank faster. Mexico's iGaming activity index fell 35% from its December 2025 peak, and the damage fell almost entirely on locally licensed brands, which lost 34% of index value while international brands lost under 7%. With offshore alternatives available, activity moved rather than stopped, so H1 2026 receipts landed 0.2% down in real terms.

Can you use crypto at licensed casinos in these markets?

Not in Peru. Article 38.d of DS 005-2023-MINCETUR prohibits cryptocurrency transactions for licensed operators outright, so stakes and prizes must move through legal tender, cards or bank rails. Mexico's permit perimeter is fiat too – Stake's May 2026 Mexican launch under a SEGOB permit structure runs on peso rails. In Argentina, no provincial framework licenses crypto-denominated play, so crypto casinos serving Argentine players operate offshore.
