  1.  Each person who wishes to claim the credit allowed under this chapter shall obtain the appropriate forms from the assessor and file the claim with the assessor. The director of revenue shall prescribe suitable forms and instructions for such claims, and make such forms and instructions available to the assessors.
  2.  a.  (1)  Claims for the business property tax credit against taxes due and payable in fiscal years beginning before July 1, 2017, shall be filed not later than March 15 preceding the fiscal year during which the taxes for which the credit is claimed are due and payable.
  (2)  Claims for the business property tax credit against taxes due and payable in fiscal years beginning on or after July 1, 2017, shall be filed not later than July 1 preceding the fiscal year during which the taxes for which the credit is claimed are due and payable.
  b.  A claim for credit filed after the deadline for filing claims shall be considered as a claim for the following year.
  3.  Upon the filing of a claim and allowance of the credit, the credit shall be allowed on the parcel or property unit for successive years without further filing as long as the parcel or property unit satisfies the requirements for the credit. If the parcel or property unit ceases to qualify for the credit under this chapter, the owner shall provide written notice to the assessor by the date for filing claims specified in subsection 2 following the date on which the parcel or property unit ceases to qualify for the credit.
  4.  The assessor shall remit the claims for credit to the county auditor with the assessor’s recommendation for allowance or disallowance. If the assessor recommends disallowance of a claim, the assessor shall submit the reasons for the recommendation, in writing, to the county auditor. The county auditor shall forward the claims and recommendations to the board of supervisors. The board shall allow or disallow the claims.
  5.  For each claim and allowance of a credit for a property unit, the county auditor shall calculate the average of all consolidated levy rates applicable to the several parcels within the property unit. All claims for credit which have been allowed by the board of supervisors, the actual value of such parcels and property units applicable to the fiscal year for which the credit is claimed that are subject to assessment and taxation prior to imposition of any applicable assessment limitation, the consolidated levy rates for such parcels and the average consolidated levy rates for such property units applicable to the fiscal year for which the credit is claimed, and the taxing districts in which the parcel or property unit is located, shall be certified on or before June 30, in each year, by the county auditor to the department.
  6.  The assessor shall maintain a permanent file of current business property tax credits. The assessor shall file a notice of transfer of property for which a credit has been allowed when notice is received from the office of the county recorder, from the person who sold or transferred the property, or from the personal representative of a deceased property owner. The county recorder shall give notice to the assessor of each transfer of title filed in the recorder’s office. The notice from the county recorder shall describe the property transferred, the name of the person transferring title to the property, and the name of the person to whom title to the property has been transferred.
  7.  When all or a portion of a parcel or property unit that is allowed a credit under this chapter is sold, transferred, or ownership otherwise changes, the buyer, transferee, or new owner who wishes to receive the credit shall refile the claim for credit. In addition, when a portion of a parcel or property unit that is allowed a credit under this chapter is sold, transferred, or ownership otherwise changes, the owner of the portion of the parcel or property unit for which ownership did not change shall refile the claim for credit.
