Enterprise Zone Pre-Certification and Certification

Businesses wanting to claim any of the Colorado Enterprise Zone (EZ) income tax credits (excluding the Contribution Project credit for which pre-certification is not required), must annually pre-certify with their local EZ Administrator to be eligible to claim EZ tax credits. A business having pre-certified and completed activities that are eligible for EZ credits must then complete a certification application and receive approval from the local EZ Administrator. Certification documents should be submitted with your Colorado income tax filing.

EZ Pre-Certification Attestation
I, the business owner/authorized company official, certify that I am aware of the Enterprise Zone program, that Enterprise Zone tax credits are a contributing factor to the startup, expansion or relocation of my business in the Enterprise Zone, and I acknowledge that this Pre-certification is for activities that shall commence after the date that Pre-certification is granted by my local Enterprise Zone Administrator through the end of my business's current income tax year.

Pre-certification is approved by the Local EZ Administrator; a business with multiple locations in an EZ may include all locations within that EZ on a single pre-certification application. Businesses with multiple locations in various EZs must complete an application for each EZ.
