Iowa Code Title VIII. Transportation [Chs. 306-330B] § 321.106. Registration for fractional part of year

1. When a motor truck, truck tractor, or road tractor is registered by the county treasurer pursuant to section 321.120, 321.121, or 321.122 and there is no delinquency and the registration is made in February or succeeding months through November, the annual registration fee shall be prorated for the remaining unexpired months of the registration year. A fee shall not be required for the month of December for a vehicle registered on a calendar year basis on which there is no delinquency. However, when such a vehicle is registered in November, the vehicle may be registered for the remaining unexpired months of the registration year or for the remaining unexpired months of the registration year and for the next registration year, upon payment of the applicable registration fees.

2. When a vehicle is registered under chapter 326 and there is no delinquency and the registration is made in the second through eleventh month of the registration year, the annual registration fee shall be prorated for the remaining unexpired months of the registration year. However, when such a vehicle is registered in the eleventh month of the registration year, the vehicle may be registered for the remaining unexpired months of the registration year and for the next registration year, upon payment of the applicable registration fees.

3. When a vehicle is registered on a birth month basis and there is no delinquency and the registration is made in the month after the beginning of the registration year or succeeding months, the annual registration fee shall be prorated for the remaining unexpired months of the registration year. A fee shall not be required for the month of the owner's birthday for a vehicle on which there is no delinquency. However, when a vehicle registered on a birth month basis is registered during the eleventh month of the registration year, the vehicle may be registered for the remaining unexpired months of the registration year or for the remaining unexpired months of the registration year and for the next registration year, upon payment of the applicable registration fees.

4. If a fee computed under this section contains a fractional part of a dollar, the fee shall be computed to the nearest whole dollar. A fee computed under this section shall not be less than five dollars. The fee so computed shall be deemed to be the annual registration fee for the remainder of the registration year. This subsection does not apply to vehicles registered under chapter 326.

5. A reduction in the annual registration fee shall not be allowed by the department until the applicant files satisfactory evidence to prove that there is no delinquency in registration.
