Promoted activities

  • The list of promoted activities included in the Provincial Law (“Promoted Activities“) is attached as an Annex to the same. The Promoted Activities list may be extended and/or modified by the enforcement authority — to be determined by the Executive Branch of the Province — with prior notice to the Tax Authority of the Province (“Tax Authority“).
  • Some of the Promoted Activities are the development and fine-tuning of software products, consulting services in computer equipment, data processing, data hosting and services for the use of digital platforms for the commercialization of goods and services.

NeCo registry

  • The Provincial Law also creates the Knowledge Economy Node Program (“NeCo“) for purposes of developing the Promoted Activities, designing public policies for science, technology and production and creating new productive sectors in the Province. 


  • Legal entities that (i) are located in the territory of the Province, (ii) develop — as their main activity — any of the Promoted Activities, (iii) can evidence their registration with the national regime and (iv) are registered with the NeCo registry (“Beneficiaries“) will be eligible for the benefits set forth by the Provincial Law.

Benefits, stability and tax treatment for Beneficiaries

  • Those who wish to access the benefits set forth by the Provincial Law must register in the NeCo registry.

  • Certain exemptions to the gross income tax corresponding to the income obtained from the development of the Promoted Activities are provided to micro, small and medium-sized companies and large companies. 
  • Special benefits will be granted to poles and/or parks and/or technological districts.
  • The continuity of the benefits granted will be revalidated once every two years and up to the maximum term in which the national law and amendments thereof will be in force (31 December 2022), including its eventual extensions and the provisions of the eventual regulation of the Provincial Law.
