The Pima Industrial Development Authority (IDA) offers a Mortgage Credit Certificate (MCC) Program to help homebuyers finance their home purchase.  Community Investment Corporation (CIC) is the program administrator and determines participant eligibility, issues certificates for qualified applicants, and performs program administration.

What is a Mortgage Credit Certificate?

An MCC is a tax credit that reduces your federal tax liability.  You receive a tax credit for 40% of your annual mortgage interest (up to $2,000 annually) for as long as you own and remain in the home purchased.


$125,000 Loan Amount
X 4% Interest
= $5,000 Interest the first year
X 40% MCC Credit
= $2,000 Tax Credit!

How to Apply

Application into the program is typically requested by your lender; however, you may also apply directly with CIC by completing the MCC application and by providing the required documents.

Required Documents

  • MCC Application
  • Copy of Loan Application (Form 1003)
  • Previous three years of applicant’s Federal Tax returns

Documents can be submitted via mail, fax, in person, or you may upload them here.  Upon receipt of your documents, CIC will contact you to set up an appointment to meet and process the application.  If you’d like help completing the application, please call to schedule an appointment.  The MCC Application must be notarized and we have a notary on staff.
