Extends interest payment requirements to refunds of credits under the natural resources and environmental protection act beginning January 1, 2017, applying the same interest calculation rules as income tax and business tax refunds.

Requires the department to notify taxpayers within 45 days if a credit refund has not been paid, informing them whether their return was complete.

Applies interest calculation provisions from subsections (3), (4), (5), and (6) to credits for contracts approved and processed by the department of agriculture and rural development.

Credits must meet the same conditions as other refunds, including being timely filed, complete with no calculation errors, and containing all required documentation and state/federal forms.
