(1)  For taxable years beginning on or after January 1, 2018, and before January 1, 2026, there shall be allowed to a taxpayer a nonrefundable credit against the tax imposed by this chapter in the amount of two hundred five dollars ($205) with respect to each qualifying child of the taxpayer. For purposes of this section, the term "qualifying child" has the meaning as defined in section 24(c) of the Internal Revenue Code. In no event shall more than one (1) taxpayer be allowed this credit for the same qualifying child. This credit is available only to Idaho residents. Any part-year resident entitled to a credit under this section shall receive a proportional credit reflecting the part of the year in which the part-year resident was domiciled in Idaho.
(2)  In the case of divorced parents or parents who do not live together, if the qualifying child is in the custody of one or both of the child’s parents for more than one-half of a calendar year, such child is the qualifying child of the custodial parent for the taxable year beginning during such calendar year. However, the child may be the qualifying child of the noncustodial parent if either of the following requirements are met:
(a)  A court of competent jurisdiction has unconditionally awarded, in writing, to the noncustodial parent the tax benefits associated with the child pursuant to section 32-706, Idaho Code, and the noncustodial parent attaches a copy of the court order to the noncustodial parent’s income tax return for the taxable year; or
(b)  The custodial parent signs a written declaration that such custodial parent will not claim the credit of this section with respect to such child for any taxable year beginning in such calendar year and the noncustodial parent attaches such written declaration to the noncustodial parent’s income tax return for the taxable year beginning during such calendar year.
