Bioscience Enterprise Corridor Zone


As part of its extensive Enterprise Zone programs, the State of Connecticut encourages the development of biotech businesses and related properties in targeted geographical areas.

Key Incentives for Businesses

For qualifying manufacturers: Companies involved in manufacturing, research associated with manufacturing and distribution warehousing (new construction/expansion only) may benefit from:

  • a five-year, 80% property tax abatement; and
  • a 10-year, 25% business tax credit. 

For qualifying service companies: Certain service companies may also be eligible for these benefits based on several sliding scales:

  • If they invest $20-90 million: a five-year, 40% property tax abatement on real estate and/or equipment; or
  • if they invest more than $90 million: a five-year, 80% property tax abatement on real estate and/or equipment.
  • If they create 300-599 jobs: a 10-year, 15% business tax credit; up to
  • if they create 2,000+ jobs: a 10-year, 50% business tax credit.


This zoning can benefit those Connecticut businesses that meet the following criteria:
  • are willing to renovate an existing facility by investing at least 50% of its pre-acquisition value in the renovation, OR construct a new facility, OR expand an existing facility, OR acquire a facility that has been idle (minimum period of idleness depends on average number of employees);
  • are engaged in bioscience*, biotechnology, pharmaceutical or photonics research, development or production;
  • have had no more than 300 employees at any time during the preceding 12 months;
  • are located in certain census blocks, groups and tracts in Farmington, Hartford, Bristol, New Britain and Plainville.

*Bioscience businesses are defined as those involved in the study of genes, cells, tissues, and chemical and physical structures of living organisms.

How to Apply

  1. Before starting any project, the business must first submit a formal request — preferably through the local economic development office for the town.
  2. That application — along with any additional required documents — must be submitted to the Department of Economic and Community Development (DECD) prior to October 1 of the year in which the project will be completed.  
  3. If approved, DECD will issue a Certificate of Eligibility within a few weeks.


Several municipalities have already been designated as a Bioscience Enterprise Zone. For additional information about developing properties in these areas, we encourage you to reach out to the appropriate contact below.
