(2) For taxable years beginning in 2004, a taxpayer’s modified adjusted gross income in excess of $42,000 ($85,000 for a joint return) is taken into account in determining the reduction under § 25A(d)(2)(A)(ii) in the amount of the Hope Scholarship and Lifetime Learning Credits otherwise allowable under § 25A(a).
.06 Earned Income Credit . (1) In general . For taxable years beginning in 2004, the following amounts are used to determine the earned income credit under § 32(b). The “earned income amount” is the amount of earned income at or above which the maximum amount of the earned income credit is allowed. The “threshold phaseout amount” is the amount of adjusted gross income (or, if greater, earned income) above which the maximum amount of the credit begins to phase out. The “completed phaseout amount” is the amount of adjusted gross income (or if greater, earned income) at or above which no credit is allowed.
.02 Unearned Income of Minor Children Taxed as if Parent’s Income (the “Kiddie Tax”) . For taxable years beginning in 2004, the amount in § 1(g)(4)(A)(ii)(I), which is used to reduce the net unearned income reported on the child’s return that is subject to the “kiddie tax,” is $800. (This amount is the same as the $800 standard deduction amount provided in section 3.10(2) of this revenue procedure.) The same $800 amount is used for purposes of § 1(g)(7) (that is, in determining whether a parent may elect to include a child’s gross income in the parent’s gross income and for calculating the “kiddie tax”). For example, one of the requirements for the parental election is that a child’s gross income is more than the amount referenced in § 1(g)(4)(A)(ii)(I) but less than 10 times such amount; thus, a child’s gross income for 2004 must be more than $800 but less than $8,000 to satisfy that requirement.
.03 Adoption Credit . For taxable years beginning in 2004, under § 23(a)(3) the maximum credit allowed for an adoption of a child with special needs is $10,390.

The available adoption credit begins to phase out under § 23(b)(2)(A) for taxpayers with modified adjusted gross income in excess of $155,860 and is completely phased out for taxpayers with modified adjusted gross income of $195,860. (See section 3.14 for the adjusted items relating to adoption assistance programs.)
.04 Child Tax Credit . For taxable years beginning in 2004, the value used in § 24(d)(1)(B)(i) in determining the amount of credit under § 24 that may be refundable is $10,750.
.05 Hope and Lifetime Learning Cred- its .
(1) For taxable years beginning in 2004, 100 percent of qualified tuition and related expenses not in excess of $1,000 and 50 percent of such expenses in excess of $1,000 are taken into account in determining the amount of the Hope Scholarship Credit under § 25A(b)(1).
