How much does the employer contribution rise in August? The payroll math to do before the next run

From the August 2026 payroll the employer's pension contribution reaches 3.5%. A month earlier, collection of unpaid contributions was centralized and the Treasury took over the pre-litigation stage. Together they change the price of an oversight most companies discover far too late. How much does it actually rise, and what should be checked now?

June and July brought two changes in Chile that, taken separately, look like housekeeping. First, the centralized system for collecting pension contributions went live, and the pursuit of unpaid contributions stopped being scattered across individual fund managers. Then the Treasury began contacting employers carrying pension debt to settle before anything reaches a courtroom. August brings the third: the employer’s contribution goes up.

None of this is a surprise. All of it flows from the pension reform, Law No. 21,735 (Ley N° 21.735), published on March 26, 2025, phased in over nine years. What has changed is not the rule but the odds that an oversight will cost something. Until now a payroll inconsistency could survive for years with nobody looking. That margin is gone.

This guide is for the small or mid-sized employer who wants to run the numbers before the August payroll, and to find out along the way whether the company is carrying a debt it does not know about.

What actually changes in August 2026

Two separate things, worth not confusing.

1. The employer’s contribution rises. From the August 2026 payroll it reaches a total of 3.5% of taxable remuneration.
2. Collection got harder. The centralized system has been running since June, and since July the Treasury handles the pre-litigation stage.

The employee’s deduction does not move.

Does the worker pay more?

No, and it is worth saying so before the payslip arrives, because it is the first question that comes up.

The employee’s deduction stays at the familiar 10%, paid into their individual retirement account. What rises is the employer’s contribution, an additional company cost rather than a cut to net pay. A correctly issued August payslip will show the worker exactly the same deduction as July’s.

What does each worker cost?

The employer’s total reaches 3.5% of taxable remuneration from the August payroll.

There is a point here that causes confusion and is worth pinning down, because it changes the size of the problem: that 3.5% is not all new. Inside the total sits the disability and survivorship insurance (SIS), which employers were already funding and whose collection now moves to the social insurance scheme run by the new autonomous pension protection fund (FAPP), along with the 1% that has applied since last August. What gets added this year is the start of the protected-return contribution (CRP), on the order of one percentage point. The cash impact is real, but a good deal smaller than it looks to anyone who reads “3.5%” as an entirely new charge.

An example. A worker on taxable pay of $700,000 pesos:

• 3.5% of $700,000 = $24,500 pesos a month in employer contributions.
• With five workers in that bracket: $122,500 pesos a month, or roughly $1,470,000 pesos a year.

Run this against your own payroll before August, and project it into 2027 and 2028 as well, because the phase-in keeps climbing. It is not a number anyone enjoys meeting for the first time on the payroll run.

The reform was designed to rise slowly and in plain sight. What blindsides a small company is almost never the new percentage. It is the old debt, surfacing because somebody has finally started collecting it.

When is payment due?

Contributions for one month are paid in the following month:

• By the 10th of the following month, paying in person.
• By the 13th, where payment is made electronically.

August contributions, in other words, are paid in September. Late payment carries indexation and interest, and today it escalates faster than it used to.

Why the centralized collection system matters

Until now each fund manager chased the contributions owed to it separately. Under the consolidated system (SUCC), collection is centralized and coordinated across the pension fund managers (AFP), the Social Security Institute (IPS) and the Treasury (TGR), which has taken over pre-litigation collection. The system also cross-checks information with other state bodies, so inconsistencies that used to sit in separate files now surface together.

Two practical consequences, which are the ones a company feels:

• The debt becomes visible. A gap between what was declared and what was paid, or between the payroll and the contracts actually in force, stops being a matter between the company and one fund manager and becomes a consolidated record.
• Pension debt bites outside employment law. It has become an adverse marker with lenders, and it tends to appear precisely when a company applies for credit or a working capital line. That is the worst possible moment to find out.

What about a debt the company never knew about?

It happens more often than people assume, and it rarely involves bad faith. Two categories are worth separating, because they are fixed in different ways:

• Declared and unpaid. The contributions were reported and not paid. At least there is a record, the amount is known and putting it right is arithmetic.
• Neither declared nor paid. No payment and no declaration, or no proper record that the employment relationship ended or was suspended, so the system carries on assuming a contract that in fact finished.

The second is the treacherous one. A badly reported settlement agreement, a worker who left but stayed on the payroll, a mishandled leave record or a half-closed contract all generate a debt that surfaces months later, by then with interest and already in collection. And because it never began as a decision not to pay, nobody is looking for it.

What does non-payment cost?

Missing pension contributions is not just another administrative delay. The exposure includes:

• Indexation and interest on the arrears, running from the due date.
• Centralized collection, with the Treasury handling the pre-litigation stage and court action behind it.
• Labor inspectorate audits and fines, from the Dirección del Trabajo (DT).
• Financing difficulties, given the weight pension debt now carries as a commercial marker.
• Void dismissal. Dismiss a worker with unpaid contributions and the dismissal does not end the obligation to pay wages: the company must keep paying remuneration and other benefits until it validates the dismissal, meaning it pays the arrears and notifies that payment to the worker. This is the Bustos rule, which lives in article 162 of the Labor Code, and it is comfortably the most expensive item on the list.

That last one deserves its own paragraph. A dismissal budgeted at three months of severance can turn into an open-ended obligation if an unpaid contribution from an old period comes to light. Checking beforehand costs one hour of administrative work. Skipping it can cost several months of salary.

Six steps before August

1. Rerun the payroll. Apply 3.5% to each taxable salary and project the monthly and annual cost, bearing in mind that the phase-in keeps rising in the years ahead.
2. Check for existing debt. Compliance certificates and unpaid contribution searches are available through the public channels and the payment platform itself. Far better to find it internally than through a collection notice.
3. Tidy up contract terminations. Confirm that every departing worker was properly reported and documented, and that no terminated contract is still showing as active. That is where undeclared debt is born.
4. Reconcile four documents every month: attendance, payslip, the pension payment schedule and the payment receipt. If they do not line up, fix it before closing, not next month.
5. Keep the receipts. They are the evidence in a worker’s claim, in an inspection, and against the collection system itself when the consolidated record does not match the company’s reality.
6. Set a reminder for the 10th and the 13th of each month. It sounds trivial, but most pension debt at a small company starts with a month that got away.

What not to do

• Deferring contributions to plug a cash flow gap. It is the most expensive debt a small company can take on, and the worst-looking one afterwards.
• Leaving departed workers active on the payroll, even “just for a few days, while we sort out the paperwork.”
• Assuming that no complaint means no debt. With collection centralized, silence stopped being evidence of anything.
• Dismissing anyone without first confirming that contributions are fully paid.

Getting the pension side in order is usually a good moment to look at the rest of the company’s compliance, which is the work of our corporate compliance practice. And if the debt that surfaces is an old one, it is worth asking whether it is still enforceable at all: limitation periods are a subject in themselves, and we cover them in Statute of limitations on SII and Tesorería collections.

The acronyms, one line each

They show up on payslips, on the payment schedule and in collection letters, almost never with their full name beside them. All of them are Spanish acronyms, and they are what a Chilean payroll actually looks like.

• AFP. The private pension fund manager. It receives the worker’s own contribution and the share of the employer’s contribution that goes into their individual account.
• SIS. Disability and survivorship insurance. Employer-funded, it covers the pension of a worker who becomes disabled and of the family if the worker dies. It sits inside the 3.5%, not on top of it.
• FAPP. The autonomous pension protection fund. It runs the social insurance scheme created by the reform and takes the share of the employer’s contribution that does not go into the individual account.
• CRP. The protected-return contribution. This is the piece that starts being paid in August and the reason for this year’s jump.
• SUCC. The consolidated contribution collection system: the machinery that now pursues arrears, with the Treasury (TGR) running the pre-litigation stage and the Social Security Institute (IPS) inside the coordination.
• DNP and DNPA. The two shapes pension debt takes: declared and unpaid, or neither declared nor paid. The second is the one that usually starts with a badly closed contract.
• APV and APVC. Voluntary pension savings and their collective version. The first is the worker’s own decision; the second is an agreement between the company and its workers where both put money in. Neither is compulsory and neither forms part of the 3.5%, but they share the payroll with it, which is where the confusion starts.
• AFC. The unemployment fund manager, which collects unemployment insurance. That is a separate employer contribution and runs on its own track.

In short

August raises the cost per worker, by considerably less than the headline suggests, and collection of what was already owed became faster, better coordinated and much more visible. The company that puts its payments and its contracts in order now avoids fines, interest and, above all, the problem of discovering a debt at the exact moment it needs financing.

The reform was phased precisely to give employers time. In this case, that time is measured in weeks.
