Limitation of property tax debt: the three years, what interrupts it, and the settlement agreement that revives the debt

Quick answer: the Fisco's right to collect property tax becomes time barred after three years, counted from the date the legal deadline to pay each instalment expired. But limitation does not apply on its own: it has to be pleaded, and there are three acts that interrupt it and restart the clock from zero, including signing a payment settlement agreement. That is the point that ends up costing the most: an agreement that includes instalments already time barred revives that debt. And watch out for something that is causing a lot of confusion: the administrative limitation the Treasury declares ex officio under law 21.713 does not extend to property tax.

The typical scene is a collection letter with a frightening figure, made up of instalments from many years. The first reaction is to call the Treasury and ask for a settlement agreement to ease the pressure. That is, almost always, exactly what you should not do before checking the dates.

How long the debt lasts and from when it is counted

The period is three years and runs independently for each instalment, from the date the legal deadline to pay it expired. That means an old debt can contain both time barred instalments and still valid ones side by side, and the job is to separate one from the other.

Limitation does not declare itself. No agency is going to wipe out the debt for you. It has to be pleaded, and pleaded at the right time and in the right place. As long as nobody pleads it, the debt keeps appearing and keeps accruing adjustments and interest.

The three acts that restart the clock

Interrupting limitation means wiping out the time that has passed and starting the count again. There are three, and it is worth being able to recognise them:

Each of these acts starts a new three year period. That is why a fifteen year old debt can be perfectly valid if there were settlement agreements or demands in the meantime.

The payment settlement agreement, and why it is worth looking before you sign

A payment settlement agreement is a written acknowledgement of the debt. It interrupts limitation of what was still enforceable, which is to be expected. What a lot of people do not know is the other side of it: if the agreement includes instalments whose limitation period had already run, that acknowledgement acts as a waiver of the limitation already gained, and those instalments become collectable again.

In other words, it is possible to walk into the Treasury with a debt that is mostly time barred and walk out with a debt that is fully enforceable again, without anyone having done anything irregular. It was simply signed before checking.

The correct order. First request the breakdown of the debt by period, then establish which instalments are out of time and whether there were any interruptions, and only then decide whether to settle, pay or plead limitation. A settlement agreement can always be signed later. A limitation right that has been waived does not come back.

Where and when it is pleaded

In the collection proceedings brought by the Treasury, limitation is raised as a defence, within the period that opens with the demand for payment, which is ten days. It is a short and strict deadline: once it passes, that route closes for that stage.

There is also a mechanism that rescues cases that seemed lost: abandonment of proceedings. If the judicial collection action has been paralysed by inactivity for three years counted from the last useful step taken, you can ask for it to be declared abandoned. Once abandonment is declared, the judicial demand that had interrupted limitation is left without effect, and the count runs again from the original due dates of each instalment. It is one of the most useful tools, and one of the least used.

The current confusion: law 21.713 does not cover property tax

Law 21.713 allowed the Treasury to declare certain old State debts time barred ex officio, without the need for a court case. Many people assumed their property tax debt was included. It is not: property tax is expressly among the debts excluded.

So limitation of property tax debt still follows the usual path: it is pleaded, and pleaded within the proceedings. It is still worth requesting an updated certificate of State debts from the Treasury, because that shows precisely what is being claimed and for which periods. And if the owner is a senior citizen, it is worth checking in parallel whether they qualify for any reduction or exemption, because being up to date is a requirement of the benefit that has been in force since 2027.

What happens if nothing is done: garnishment and auction

When nobody deals with it, property tax collection ends in the garnishment and auction of the property, with the same consequences we covered when discussing properties bought at auction. It is not an empty threat: it is the natural outcome of the enforcement procedure.

In between there are several stages and several opportunities to step in, which is why ignoring the notices is so costly. Most of the cases that reach us too late do not arrive late because the debt is large, but because the deadlines during which there was a defence available were allowed to pass.

The debt follows the property, not the person

This point deserves its own section, because it completely changes a buyer's position.

Article 25 of law 17.235 establishes that property tax is paid by the owner, and the obligation is treated as attached to the property rather than to the person. It is the same logic that means certain planning problems travel with the property rather than with whoever caused them. The practical consequence: anyone who buys a property with unpaid property tax inherits that debt, even though they did not create it.

A buyer's protection lies elsewhere. Articles 171 and following of the Tax Code regulate how these charges affect third parties, and the key point is registration: whatever is not registered with the Conservador before the buyer's own registration does not affect them in the same way. So, before buying:

• Request the property tax debt certificate from the Treasury, for all periods, not just the current year.
• Check the register of prohibitions and encumbrances at the Conservador, which is where any registered charge would show up.
• Do not settle for the receipt of the last payment. The fact that this half year's instalment is paid says nothing about 2019.
• Make sure the point is resolved in the deed, with a retention of the price if necessary.

It is the same kind of review we carry out in a title study, and it is the reason that process is not a mere formality.

Frequently asked questions

Does the debt disappear on its own after three years?

No. The passage of time makes limitation possible, but someone has to plead it in the proceedings. As long as it is not pleaded, the debt keeps appearing, keeps growing and keeps enabling collection.

I signed a settlement agreement years ago and never paid it. Does that help?

It does help, but against you: that agreement interrupted limitation and restarted the clock. The good news is that time also runs from the breach of the agreement, and if the collection action was then paralysed, there may be room for abandonment of proceedings.

I bought a house and received a debt from before the purchase. Do I have to pay it?

This is the scenario the law resolves against the unwary buyer, because the obligation travels with the property. Two things need to be checked: whether those instalments are time barred, and whether the charge was registered before your own registration. And separately, if the seller concealed the debt, there is a claim available against them.

Can I ask the Treasury to declare my property tax debt time barred?

The ex officio administrative declaration under law 21.713 does not cover property tax. What you can do is request the certificate of State debts to get the exact breakdown by period, which is the input you then use to plead limitation wherever it applies.

My property has been garnished. Can anything still be done?

It depends on the stage the proceedings are at, which is why the first step is to review the file, not to guess. There are stages where you can still raise defences, others where abandonment of proceedings is the route, and others where what is needed is negotiating to avoid the auction. What does not work is waiting.

Do interest and penalties also become time barred?

They follow the fate of the principal: if the instalment is time barred, its accessories are not charged. That is why the calculation is done instalment by instalment, not on the total shown in the statement.

What if the appraisal was actually wrong all those years?

These are two separate discussions, and it is worth not mixing them up. Limitation is about whether the debt is still enforceable; an incorrectly set appraisal is corrected through the grounds and deadlines we explain in how to reduce your property tax, and any overpayment is recovered following the refund guide.

How we work on it

The first step is the breakdown of the debt period by period and a review of whether there were any interrupting acts: signed settlement agreements, notices, demands. That shows which part of the debt is actually enforceable today, which is almost never the figure on the letter.

Next comes the decision, and it is a strategic one: plead limitation, request abandonment of proceedings, negotiate, or combine approaches. What we do not do is send someone off to sign a settlement agreement before that review.

If the debt comes from a property that is not even properly registered, which happens more often than you would think, we resolve it with a title study and with regularisation of title. And the tax side itself is handled by our property tax team.

Send us the roll number and the letter or collection file you received, and we will tell you which part of that debt is out of time, whether anything interrupted it, and what needs to be done first.
