Chile's Court Keeps Investment Tax Breaks, Kills Environmental Compensation Clause

What the Court Approved and Struck Down in Chile's Reactivation Law

Chile's Constitutional Court issued its ruling late Thursday on the reconstruction and national reactivation law, clearing most of the government's investment stabilisation package while invalidating a controversial environmental compensation mechanism. The court upheld nearly all of the tax invariability regime for projects of at least US$50 million, covering domestic and foreign investors with staggered terms of 10, 15 or 20 years depending on the size of the investment and a 1.5 percentage-point premium over the First Category Tax.

It did, however, delete the so-called 'entre otros' and 'proyectos conexos' articles that would have allowed the benefit to be stretched across other sectors and connected projects. The court also struck down in full the provision that would have compensated investors for direct expenses when an approved environmental qualification resolution, or RCA, was annulled or left without effect. Parliament had attempted to reframe that compensation as an indemnity and to make it taxable, but the court still removed the mechanism.

The ruling also excludes small aquaculture concession relocations from the law, meaning those moves would not be able to bypass the Environmental Impact Assessment System. The court has not yet decided whether to invalidate the article requiring basic service companies to reconnect customers free of charge after emergency supply cuts. President José Antonio Kast is expected to sign and publish the law in the Official Gazette within days.

Where the Verdict Leaves Investors, Aquaculture and Municipal Budgets

Tax stability survives, but the scope is narrower than Congress intended

The central selling point for large investors remains in place: foreign investors can lock in the effective maximum tax burden that applies at the moment they sign the contract with the state, and the stability period stretches from 10 to 20 years based on the investment amount. This is a competitive signal to mining, energy and infrastructure capital. But the court removed the broad clauses that would have extended the benefit by ministerial discretion or linked projects. In practice, each project must qualify on its own, and advisers should not assume related facilities or future expansions are automatically covered.

The RCA compensation backstop disappears entirely

The most significant defeat for project owners is the loss of state compensation when a court annuls an environmental permit. The legislative attempt to rename 'restitución' as 'indemnización' did not save the article, and the same ruling makes clear that the only effect of an annulled or invalidated RCA is no compensation, and it is incompatible with also suing the state for lack of service over the same facts. That leaves investors bearing the full cost of direct, effective and unrecoverable expenses if a permit is overturned, a material risk in sectors with contentious environmental review.

Aquaculture operators and utilities face different regulatory paths

For aquaculture, the removal of micro-relocations means concession movements still have to pass through the ordinary SEIA route unless a future law changes that. For utilities, the unresolved article on free reconnection during emergency supply cuts creates a live operational and financial question. Until the TC rules, basic service companies cannot assume they will be required to absorb reconnection costs, but they also cannot rule it out; emergency-response budgets may need to remain flexible.

Municipal tax relief is now fully compensated, with stricter access

The 100% property-contribution exemption for people aged 65 and over on their principal home remains in the law. The approved change shifts the compensation mechanism: municipalities will receive the full amount of forgone revenue through transfers from general government funds, replacing the earlier approach that offset only part of the shortfall through the Municipal Common Fund. Access is also tightened: beneficiaries must be current on waste-collection charges and the previous year's territorial tax and must submit a sworn declaration, while municipalities gain stronger tools for collecting waste and trade-patent debts.

New labour and health credits alter payroll planning

The law limits the employment credit to workers at export services companies in the knowledge economy, with a 15% base that rises for women, workers under 25, and companies headquartered outside the Metropolitan Region or in rural communes within it, capped at 75 UTM per worker per year. A separate benefit allows employers to claim up to 150 UTM per worker against the First Category Tax for financing catastrophic illness treatment, provided the employee has at least three years' service and up-to-date social security contributions. These are targeted incentives, not general payroll relief.

What Companies and Municipalities Should Do Before Promulgation

Because the TC ruling changes specific provisions and President Kast is expected to publish the law in the coming days, the following steps follow directly from the approved text.

• For investors in projects of at least US$50 million: model the staggered invariability terms of 10, 15 and 20 years and the 1.5 percentage-point premium, and do not assume 'proyectos conexos' or other sectors are covered; the court deleted those extension clauses.
• For project developers: remove any expected state compensation if an approved RCA is later annulled or left without effect; the entire compensation article was struck, despite the attempted change from 'restitución' to 'indemnización'.
• For aquaculture concessionaires: treat any planned micro-relocation as excluded from this law and requiring the normal SEIA route, unless future legislation provides otherwise.
• For basic service utilities: keep emergency-reconnection procedures flexible until the Constitutional Court decides the free-reconnection article; that separate ruling remains pending.
• For municipalities: update revenue models for full central-government compensation of the over-65 principal-home exemption, and enforce the new compliance requirements — current waste-collection and territorial-tax payments plus a sworn declaration.
• For knowledge-economy export service employers: recalibrate payroll credits using the 15% base, the worker-profile adjustments for women and under-25s, the regional uplift of five percentage points, and the annual cap of 75 UTM per worker.
• For employers considering catastrophic-illness support: document the three-year seniority and up-to-date contribution tests to claim up to 150 UTM per worker against the First Category Tax.
