Property tax and older adults: the reduction that already exists and the exemption in force from 2027

Quick answer: two different things coexist today, and it is worth not confusing them. One is the reduction that already exists, which the Servicio de Impuestos Internos (the Chilean tax authority) applies automatically to older adults based on their income and their home's fiscal appraisal, cutting the property tax instalment by 100% or by 50%. The other is the mega reform's exemption for people over 65, which is in force from 1 January 2027, has no appraisal cap and is not automatic: it requires an annual sworn declaration. Both share one requirement that leaves a lot of people out without realising it: that the property is registered in the older adult's own name.

That last point is what makes us write this guide. In Ñuble and Biobío we see the same case every week: someone in their seventies who has always lived in the family home, who pays their property tax religiously, and whose property is still registered in the name of a parent who died thirty years ago. As far as the State is concerned, that person is not the owner. No benefit reaches them.

What is already in force: the reduction under the older adult benefit

This reduction is not new and does not depend on the reform. The tax authority calculates and applies it on its own, cross checking the information it already holds, and notifies people by letter or email. There is no need to go to the office or file any forms.

The requirements, with the figures in force at the time of this update:

The amounts are adjusted and the figures age. Those above correspond to the second half of 2026 and are useful for knowing whether you are close to the limit or well within it. Before making a decision it is worth checking the current figure on the tax authority's website, because the half yearly adjustment moves the caps upward.

What is coming: the mega reform's exemption, from 2027

The mega reform introduced a different and considerably broader exemption. Congress passed it on 4 August 2026, and the point that was hardest to settle was not the benefit itself but how to compensate the municipalities that will stop receiving that revenue.

These are its features, according to the text as passed:

There are specific rules for the cases that are, in practice, the majority:

• Property held in common. All the co-owners must be natural persons, and at least one must live in the property and hold at least 50% of the rights.
• Inherited property. The surviving spouse or civil partner qualifies with a share of at least 25%.
• Mixed use. If the property also contains a shop or an office, the exemption applies when at least half the built area is residential and the owner lives there.

Be careful with the sworn declaration. A false declaration is punished with a fine of 300% of the tax and the loss of the benefit for ten years, across all your properties. It is not a form to fill in from memory: you need to check beforehand that the ownership and the residence are as the law requires.

One honest point, because a lot of rushed information is circulating: as of this update we have not been able to confirm publication of the text in the Diario Oficial with a law number. What is settled is its content and its date of entry into force. If someone offers to process today a benefit that only starts in 2027, be suspicious.

The two, compared

The requirement that leaves the most people out: ownership

Both benefits require the property to be registered in the older adult's name. It is not enough to have lived there your whole life, or to have paid the property tax, or for the family to take it for granted. The tax authority looks at the registration, and the registration is the one held by the Conservador de Bienes Raíces (the Chilean property registry).

These are the three scenarios we see most often, and none of them qualifies as things stand:

• The house is still in the name of deceased parents. The posesión efectiva was never processed, so ownership never passed to the children. This is the most common case of all.
• It was bought as shares and rights in an undivided estate. The person appears as a co-owner of a larger property, not as the owner of their own plot. How to get out of that situation is in our guide to shares and rights in an undivided estate.
• It was bought with a private document that was never registered. An assignment, a contract signed before a notary that was left in a drawer. Without registration there is no ownership, and regularisation of title is the way to correct it.

The good news is that there is time, but not much to spare. The exemption comes into force on 1 January 2027, and the sworn declaration is filed for a property that must already be registered in the name of whoever is claiming it. A posesión efectiva and its registration do not get resolved in a week.

Frequently asked questions

Do I have to do anything to get the reduction that exists today?

No. The tax authority applies it automatically by cross checking the information it already holds, and notifies you by letter or email. What is worth doing is checking on the tax authority's website whether you were included, because if some piece of data is wrongly recorded, for example the property's registered use, the benefit will not apply and nobody is going to tell you.

Can I have both, the reduction and the exemption?

They are different benefits with different requirements. The 2027 exemption is broader because it has no appraisal cap and does not look at income, so anyone who qualifies for it will normally not need the other one. What matters is not skipping the sworn declaration on the assumption that everything runs by itself, because with the new exemption it does not.

I live in the house, but it is in my late mother's name. Do I qualify?

Not today, because you do not appear as the owner. The solution is to process the posesión efectiva for the estate and then register the property in the heirs' names with the Conservador. If there are several heirs, you also need to look at the percentages: the 2027 exemption requires the resident to hold at least half the rights, except for a surviving spouse, who qualifies with a quarter.

Does it work if I rent out a room or run a business from the house?

The 2027 exemption allows for mixed use: it applies if at least half the built area is residential and the owner lives there. The detail is that this proportion is measured against what is registered with the Municipal Building Department, so if the shop was built without a permit, the register will not reflect it, and that can work against you.

I owe back property tax. Do I lose the benefit?

The new exemption requires you to be up to date on the previous year's property tax and on waste collection charges. If there is old debt, before sorting out the benefit you need to check how much of that debt is still enforceable, because not everything that appears on the account is. We cover that point in our guide to limitation of property tax and in the one on waste collection charges.

My appraisal went up and now I am excluded from the reduction. Can anything be done?

Sometimes, yes. If the appraisal has been wrongly determined, because of a wrongly measured surface area, wrongly applied classification tables or a calculation error, there is a procedure to challenge it. How, and within what deadlines, is in how to reduce property tax.

What if the older adult has already died and the house is still in their name?

The benefit is personal and is not inherited. What needs to happen is processing the posesión efectiva and regularising the registration, and from there assessing whether any of the heirs living in the property qualifies in their own right.

How we work on this

The first thing we do is a simple registration check: who the property is actually registered to, and in what percentages. That alone tells us whether the benefit is within reach as things stand, or whether there is a prior step to take.

When that prior step is missing, it is usually one of three: the posesión efectiva and registration of the estate, regularisation of title when the purchase was never registered, or exiting a co-ownership when the property was bought as shares and rights. All three have their own timelines, which is why it is worth starting them now, not in December 2027.

If the appraisal also looks high relative to what the property actually is, we review the tax authority's property record together with what is registered with the Municipal Building Department, which is where the surface area discrepancies that push up the instalment show up.

Send us the property's rol, its property tax roll number, and the older adult's full name, and we will tell you who it is currently registered to, whether they qualify for the benefit already in force, and what would need to be done, and by when, to make it in time for the 2027 exemption.
