2026 has just begun, and with it comes a new increase in current rental contracts, which are adjusted in January . It's important to clarify that the increase will depend on the type of lease agreement signed, since currently three types of contracts remain in effect : those signed under the original rental law, those signed with its updated version, and those agreed upon after the law's repeal.
The characteristics of each modality are as follows:
- Those that were signed under the rental law: have annual adjustments by the Rental Contract Index (ICL).
- Those who did so after the update of the regulations -in October 2023-: with semi-annual adjustments for Home Ownership.
- Those agreed upon after the repeal of the law – on December 29, 2023 – were based on freedom of contract between the parties. Most of these contracts are adjusted for inflation (CPI).
However, as was the case last month, the impact will only be seen in one type of rental agreement because only those contracts signed after the repeal of the rental law —on December 29, 2023—that are indexed to the CPI (Consumer Price Index) will be updated. This is because contracts agreed upon under the old rental law—although many are still in effect—and with adjustments based on the CPI will no longer receive increases; and those signed after the update of the regulations—in October 2023—will not see another increase until April 2026.

Which contracts are updated in January
In this context, the contracts that will receive increases this month are the following:- Those signed from December 29, 2023 onwards , after the repeal of the law, with quarterly or four-monthly adjustments according to the CPI .
Increase due to CPI
From December 29, 2023 , with the repeal of the rental law, contracts began to be freely negotiated between the parties . This means that landlords and tenants can freely agree on the contract duration, the frequency of adjustments, and the index to be used.In most cases, the agreements include quarterly or four-monthly updates based on inflation, as measured by the Consumer Price Index (CPI) .
Therefore, for those who signed contracts with quarterly adjustments, the January increase will be calculated using the latest index published by INDEC (November 2025), resulting in a 7.05% increase . In concrete terms: if the rent is $600,000 , the new amount to be paid in January will be approximately $642,299 . Meanwhile, if the rent is $800,000 , the new amount will rise to $856,399 .
By ICL
It's important to clarify that, since contracts are now negotiated freely, agreements can still be finalized with adjustments based on the ICL (Consumer Price Index), but they are no longer subject to the annual adjustment requirement stipulated by law . Therefore, those who receive the January increase—with quarterly adjustments—based on this index will see a 5.91% rise (1.14% less than the CPI). This means that a salary of $600,000 will increase to $635,459 .

What happens to contracts that expire?
Contracts will also end in January; these are the ones that were agreed in the same month of 2023 and signed under the rental law: for three years and with annual adjustments under the ICL .Now, the market landscape is different : the vast majority of rental contracts are now negotiated freely between the parties , for two years with adjustments every three or four months , in pesos and tied to inflation . Therefore, both tenants whose agreements are ending and those who have chosen to continue them will have to agree to the new contract under these conditions.
