A Puerto Rico court recently upheld a ruling regarding a construction tax dispute between Aireko Construction, LLC, and the Municipio de Isabela. The court confirmed that Aireko should pay a lower tax rate on its construction project, which is significant for contractors and municipalities across the island.

The case, Aireko Construction, LLC. v. Municipio De Isabela, was filed under docket number TA2026AP00615 in the Tribunal De Apelaciones De Puerto Rico. The court's decision, issued on August 12, 2026, affects how construction taxes are calculated in Puerto Rico, particularly for projects involving the installation of sanitary pipelines.

Background

Aireko Construction, LLC, a construction company, entered into a contract with the Autoridad de Acueductos y Alcantarillados (AAA) for a significant project in Isabela, Puerto Rico, valued at approximately $14.7 million. The project involved the replacement of a trunk sewer and included various improvements. However, the Municipio de Isabela issued a construction tax of $1,175,505.68, which Aireko contested, arguing that the applicable tax rate should be lower.

Aireko asserted that under the Municipio's own regulations, the tax rate for their project should be 5% instead of the 8% that the Municipio applied. The company filed a lawsuit in the Tribunal de Primera Instancia, seeking a review of the Municipio's tax determination. The Municipio, in its defense, claimed that the project was complex and should be taxed at the higher rate.

The Ruling

The Tribunal de Apelaciones ruled in favor of Aireko, confirming the lower court's decision. The court stated, "the tax applicable to the project is 5%, as the project primarily involves the installation of pipelines, which falls under a specific category in the municipal regulations." The judges on the panel included President Judge Cintrón Cintrón, Judge Rodríguez Flores, and Judge Díaz Rivera.

The court found that the Municipio's argument for a higher tax rate was not valid, as the project was fundamentally about installing sanitary pipelines. The ruling emphasized that the specific regulations for construction taxes in Isabela should take precedence over general tax rates when applicable.

Impact

This ruling is significant for construction companies operating in Puerto Rico. It clarifies how tax rates should be applied to specific types of construction projects, particularly those involving infrastructure like sewer systems. The decision reinforces the importance of adhering to municipal regulations and could influence future disputes over construction taxes.

Additionally, the ruling may prompt other municipalities to review their tax regulations and ensure they align with state laws. This case sets a precedent for how construction taxes are interpreted and applied, potentially leading to more favorable tax conditions for contractors in similar situations.

What's Next

The Municipio de Isabela has the option to appeal this ruling to a higher court. However, as of now, there are no related cases pending that could impact this decision. The outcome of this case may lead to further legal scrutiny regarding construction taxes in Puerto Rico.
