701—304.13(422) Earned income credit.
	304.13(1) Tax years beginning before January 1, 2007. Effective for tax years beginning on or after January 1, 1990, an individual is allowed an Iowa earned income credit equal to a percentage of the earned income credit to which the taxpayer is entitled on the taxpayer’s federal income tax return as authorized in Section 32 of the Internal Revenue Code. The Iowa earned income credit is nonrefundable; therefore, the credit may not exceed the remaining income tax liability of the taxpayer after the personal exemption credits and the other nonrefundable credits are deducted. The percentage of the earned income credit for tax years beginning in the 1990 calendar year is 5 percent. The percentage of the earned income credit for tax years beginning on or after January 1, 1991, is 6.5 percent.
For federal income tax purposes, the earned income credit is available for a low-income worker who maintains a household in the United States that is the principal place of abode of the worker and a child or children for more than one-half of the tax year or the worker must have provided a home for the entire tax year for a dependent parent. In addition, the worker must be (1) a married person who files a joint return and is entitled to a dependency exemption for a son or daughter, adopted child or stepchild; (2) a surviving spouse; or (3) an individual who qualifies as a head of household as described in Section 2(b) of the Internal Revenue Code. The federal earned income credit for a taxpayer is determined by computing the taxpayer’s earned income on a worksheet provided in the federal income tax return instructions and determining the allowable credit from a table included in the instructions for the 1040 or 1040A. For purposes of the credit, a taxpayer’s earned income includes wages, salaries, tips, or other compensation plus net income from self-employment.
In the case of married taxpayers who filed a joint federal return and who elected to file separate state returns or separately on the combined return form, the Iowa earned income credit is allocated between the spouses in the ratio that each spouse’s earned income relates to the earned income of both spouses.
Nonresidents and part-year residents of Iowa are allowed the same earned income credits as resident taxpayers.
	304.13(2) Tax years beginning on or after January 1, 2007. Effective for tax years beginning on or after January 1, 2007, but beginning before January 1, 2013, an individual is allowed an Iowa earned income credit equal to 7 percent of the earned income credit to which the taxpayer is entitled on the taxpayer’s federal income tax return as authorized in Section 32 of the Internal Revenue Code. For tax years beginning on or after January 1, 2013, but beginning before January 1, 2014, an individual is allowed an Iowa earned income tax credit equal to 14 percent of the earned income credit to which the taxpayer is entitled on the taxpayer’s federal income tax return as authorized in Section 32 of the Internal Revenue Code. For tax years beginning on or after January 1, 2014, an individual is allowed an Iowa earned income tax credit equal to 15 percent of the earned income credit to which the taxpayer is entitled on the taxpayer’s federal income tax return as authorized in Section 32 of the Internal Revenue Code. The Iowa earned income credit is refundable; therefore, the credit may exceed the remaining income tax liability of the taxpayer after the personal exemption credits and other nonrefundable credits are deducted.
In the case of married taxpayers who filed a joint federal return and who elected to file separate state returns or separately on the combined return form, the Iowa earned income credit is allocated between the spouses in the ratio that each spouse’s earned income relates to the earned income of both spouses.
Nonresidents or part-year residents of Iowa must determine the Iowa earned income tax credit in the ratio of their Iowa source net income to their total source net income. In addition, if nonresidents or part-year residents of Iowa are married and elect to file separate returns or separately on the combined return form, the Iowa earned income credit must be allocated between the spouses in the ratio of each spouse’s Iowa source net income to the combined Iowa source net income.
Example: A married couple lives in Omaha, Nebraska. One spouse worked in Iowa in 2007 and had wages and other income from Iowa sources of $12,000. That spouse had a federal adjusted gross income from all sources of $15,000. The other spouse had no Iowa source net income and had a federal adjusted gross income from all sources of $10,000. The taxpayers had a federal earned income credit of $2,800.
The federal earned income credit of $2,800 multiplied by 7 percent equals $196. The ratio of Iowa source net income of $12,000 divided by total source net income of $25,000 equals 48 percent. The Iowa earned income tax credit equals $196 multiplied by 48 percent, or $94.
This rule is intended to implement Iowa Code section 422.12B as amended by 2013 Iowa Acts, Senate File 295.
