On August 1, 2026, Chile's pension reform (Law 21,735) reaches its next stage. Disability and Survivor Insurance, known by its Spanish acronym SIS, becomes one of the benefits of the newly created Social Security Pension Insurance, and the employer contributions that fund it start flowing into an autonomous fund. It is the most visible waypoint yet in a reform that adds solidarity to a system built almost entirely on individual savings. What changes, though, is mostly the plumbing. The view from the counter stays the same for now.
What Actually Changes on August 1
The destination of the money changes. The 2.5% of payroll paid by employers — the long-standing 1.5% SIS component plus the 1% added by the reform — will be remitted to the Autonomous Pension Protection Fund (FAPP) rather than routed through the AFPs, Chile's private pension fund managers. The shift is written into Law 21,735 itself and takes effect automatically, without waiting for new legislation. It is also an operational change: payroll software fields and the file format used by Previred, the country's contribution filing platform, both change, so companies must be ready when August wages are declared.
The 1.5% written into the law is a design reference, not the price. The actual premium is set by tender: according to the pension regulator, the rate in force as of April 2026 is 1.62% of taxable earnings, or 1.49% for contributors whose payments are withheld through the tax system.
What Does Not Change: the AFPs Stay in Charge
It is easy to assume the AFPs step away from disability insurance on August 1. They do not. Determining coverage, calculating the additional contribution, and paying provisional pensions remain their responsibility for now, and the medical commissions that certify disability continue to be run jointly by the AFPs and the Social Security Institute (IPS).
The FAPP takes over the tender only for the contract period beginning in August 2027. The contract now in force, covering August 2026 through July 2027, came out of the last tender the AFPs will ever run. August 1 is the first day of a two-stage handover: the funding vehicle switches first, and administration catches up a year later.
Why Add Solidarity
Chile has built its pension system around individual capitalization accounts since the 1980s. When retirement income depends almost entirely on your own accumulated balance, low wages, short careers, and time out of the workforce for caregiving push pensions structurally downward. The reform, approved by Congress in January 2025 and published in March, raises the employer contribution from 1% in August 2025 to 7% by 2033 — 8.5% once the existing 1.5% for SIS is included — and channels part of it into a shared fund rather than individual accounts. Folding SIS into that framework follows the same logic: keep disability and survivor coverage intact at the same premium even when the individual balance is thin. Detach the risk from the personal account.
The People Outside the Contributory System
SIS remains contributory insurance. It reaches employees actively contributing to an AFP, workers within twelve months of their last contribution who paid in for at least six months of the preceding year, and self-employed workers who contribute through their annual tax return. Someone who never worked, or who acquired a severe disability young and never built a record, sits outside it. The catch-all is the Basic Solidarity Disability Pension (PBSI), a non-contributory benefit for people aged 18 to 64, paying 250,275 pesos a month in 2026 and indexed to the maximum universal guaranteed pension. But it requires certification by a medical commission, membership in the poorest 80% of households under the Social Household Registry, and no pension from any other scheme.
The population involved is substantial. SENADIS's third national disability study found that 17.6% of adults — roughly 2.7 million people — live with a disability, with women (21.9%) far outnumbering men (13.1%). Note how different the argument looks from the fight in Argentina, where fiscal pressure turned eligibility screening into the battleground, while Chile is redesigning the insurance itself. I mapped the wider regional picture in an earlier piece.
A New Government, and a Timetable Under Strain
The reform passed under the previous administration, and the Kast government that took office in March 2026 inherited its implementation. The companion bill that actually moves SIS administration to the FAPP went to Congress in June 2025 and is still before the Senate Finance Committee; on July 7 the undersecretary for social security, Elisa Cabezón, presented three amendments meant to shore up implementation. Passage before year-end is considered necessary to hit the August 2027 tender.
Not everyone thinks the machinery is ready. Testifying before the same committee on May 25, the IPS warned that completion could slip into 2027 depending on how broad its own role turns out to be; under the expanded scenario — calculating benefits, making payments, handling appeals — it estimated needing roughly fifteen additional months to build up staff and systems. In March the government also withdrew from the Comptroller's office a decree setting the fees the AFPs would pay IPS for those services, leaving parts of the timetable unsettled.
My Take
What interests me most is the single move of detaching disability insurance from the individual account. Japan's disability pension is contributory too, and the way entitlement turns on which scheme you belonged to on the date of first medical consultation closely mirrors the way SIS asks whether you were contributing when the illness or accident occurred. The real difference is the non-contributory doorway. Japan builds one into the system itself: a disability basic pension for conditions arising before age 20, granted with no contribution record required. It plays a role similar to Chile's PBSI, but it applies an income ceiling rather than a means test, while PBSI screens through a poverty-ranked household registry. Two catch-alls, two different philosophies about who gets sorted out.
The relationship with work injury schemes matters too. In Japan, disability caused on the job is compensated through workers' compensation insurance, with its own grading table and its own financing, entirely separate from the disability pension. Chile likewise handles occupational accidents and diseases under a separate law, leaving SIS to cover non-occupational risk. As that non-occupational side becomes social insurance, the gap in benefit levels between the two tracks should become considerably easier to see.
Costa Rica offers a useful contrast. Its social security fund, the CCSS, bundles old age, disability, and survivorship into a single social insurance scheme known as IVM, and structurally Chile is moving toward something closer to that model. But what stayed with me from what I saw in Costa Rica is how sharply access to rehabilitation, orthoses, and wheelchairs divided along the line of whether someone was insured with the CCSS. Turning pensions into social insurance does not by itself solve the problem of people who never got into the insurance; as long as PBSI keeps its means test, the same line simply relocates. From a physiotherapist's vantage point, certification criteria are never only about income after you stop working — they shape how far a person aims to recover function and how long they keep going with rehabilitation. Seen that way, medical commissions remaining jointly run through this transition is not a small loose end.
Three things to watch. First, whether the SIS transfer bill becomes law within 2026. Second, how cleanly the August payroll cycle files contributions to the FAPP. Third, where the premium lands in the first FAPP-run tender for coverage starting August 2027, against today's 1.62%. That last number will be the first market verdict on pooling the risk.
Glossary
Seguro de Invalidez y Sobrevivencia (SIS) = disability and survivor insurance. Seguro Social Previsional (SSP) = the social security pension insurance created by the reform. Fondo Autónomo de Protección Previsional (FAPP) = autonomous pension protection fund, the new body that collects contributions and runs tenders. AFP = private pension fund manager. Pensión Básica Solidaria de Invalidez (PBSI) = basic solidarity disability pension, the non-contributory benefit for people under 65. Previred = the electronic platform for filing social contributions.
Detaching the risk from the personal account is real progress — but who was never let into the insurance is not a question the reform answers by itself.
