Certain businesses located within a qualified Enterprise Zone may be eligible for a Colorado income tax credit based on qualified expenses.  However, to be able to claim the credit, a business is now required to be pre-certified before the expense is incurred.  This only applies to businesses that are located inside an Enterprise Zone and meet certain other requirements. If you are not sure if you qualify, check with us before you try to obtain pre-certification. Pre-certification is required annually, so please add a reminder on your calendar at the beginning of each year to complete the pre-certification process. The pre-certification process can be done electronically at www.advancecolorado.com/ez. If we prepare your business or personal income tax return, please send us a copy of your accepted certification form as it is required to be filed with your income tax return to claim the Colorado Enterprise Zone income tax credits.
