701—40.17 (422) Income of part-year residents. A taxpayer who was a resident of Iowa for only a portion of the taxable year is subject to the following rules of taxation:
	  1. 	 For that portion of the taxable year for which the taxpayer was a nonresident, the taxpayer shall allocate to Iowa only the income derived from sources within Iowa.
	  2. 	 For that portion of the taxable year for which the taxpayer was an Iowa resident, the taxpayer shall allocate to Iowa all income earned or received whether from sources within or without Iowa.
A taxpayer moving into Iowa may adjust the Iowa-source gross income on Schedule IA 126 by the amount of the moving expense to the extent allowed by Section 217 of the Internal Revenue Code. Any reimbursement of moving expense shall be included in Iowa-source gross income. A taxpayer moving from Iowa to another state or country may not adjust the Iowa-source gross income by the amount of moving expense, nor should any reimbursement of moving expense be allocated to Iowa.
This rule is intended to implement Iowa Code sections 422.5, 422.7, and 422.8.
