(a) In general In the case of an eligible individual, there shall be allowed as a credit against the tax imposed by subtitle A for the first taxable year beginning in 2020 an amount equal to the sum of— (1) $1,200 ($2,400 in the case of eligible individuals filing a joint return), plus (2) an amount equal to the product of $500 multiplied by the number of qualifying children (within the meaning of section 24(c)) of the taxpayer. (b) Treatment of credit The credit allowed by subsection (a) shall be treated as allowed by subpart C of part IV of subchapter A of chapter 1. (c) Limitation based on adjusted gross income The amount of the credit allowed by subsection (a) (determined without regard to this subsection and subsection (e)) shall be reduced (but not below zero) by 5 percent of so much of the taxpayer’s adjusted gross income as exceeds— (1) $150,000 in the case of a joint return or a surviving spouse (as defined in section 2(a)), (2) $112,500 in the case of a head of household, and (3) $75,000 in the case of a taxpayer not described in paragraph (1) or (2).

(e) Coordination with advance refunds of credit (1) In general The amount of credit which would (but for this paragraph) be allowable under this section shall be reduced (but not below zero) by the aggregate refunds and credits made or allowed to the taxpayer under subsection (f). Any failure to so reduce the credit shall be treated as arising out of a mathematical or clerical error and assessed according to section 6213(b)(1). (2) Joint returns In the case of a refund or credit made or allowed under subsection (f) with respect to a joint return, half of such refund or credit shall be treated as having been made or allowed to each individual filing such return. (f) Advance refunds and credits (1) In general Subject to paragraph (5), each individual who was an eligible individual for such individual’s first taxable year beginning in 2019 shall be treated as having made a payment against the tax imposed by chapter 1 for such taxable year in an amount equal to the advance refund amount for such taxable year. (2) Advance refund amount For purposes of paragraph (1), the advance refund amount is the amount that would have been allowed as a credit under this section for such taxable year if this section (other than subsection (e) and this subsection) had applied to such taxable year. (3) Timing and manner of payments (A) Timing The Secretary shall, subject to the provisions of this title, refund or credit any overpayment attributable to this subsection as rapidly as possible. No refund or credit shall be made or allowed under this subsection after December 31, 2020 .

(C) Waiver of certain rules Notwithstanding section 3325 of title 31 , United States Code, or any other provision of law, with respect to any payment of a refund under this subsection, a disbursing official in the executive branch of the United States Government may modify payment information received from an officer or employee described in section 3325(a)(1)(B) of such title for the purpose of facilitating the accurate and efficient delivery of such payment.

(4) No interest No interest shall be allowed on any overpayment attributable to this subsection. (5) Alternate taxable year In the case of an individual who, at the time of any determination made pursuant to paragraph (3), has not filed a tax return for the year described in paragraph (1), the Secretary may— (A) apply such paragraph by substituting “2018” for “2019”, and (B) if the individual has not filed a tax return for such individual’s first taxable year beginning in 2018, use information with respect to such individual for calendar year 2019 provided in— (i) Form SSA–1099, Social Security Benefit Statement, or (ii) Form RRB–1099, Social Security Equivalent Benefit Statement.

(ii) In the case of a payment described in subparagraph (A) which is made with respect to a railroad retirement beneficiary, section 13 of the Railroad Retirement Act ( 45 U.S.C. 231 l ) shall apply to such payment in the same manner as such section applies to a payment under such Act. (iii) In the case of a payment described in subparagraph (A) which is made with respect to a veterans beneficiary, sections 5502, 6106, and 6108 of title 38, United States Code, shall apply to such payment in the same manner as such sections apply to a payment under such title.

(C) Qualifying child A qualifying child of a taxpayer shall not be taken into account under subsection (a)(2) unless— (i) the taxpayer includes the valid identification number of such taxpayer (or, in the case of a joint return, the valid identification number of at least 1 spouse) on the return of tax for the taxable year, and (ii) the valid identification number of such qualifying child is included on the return of tax for the taxable year. (2) Requirements for advance refunds No refund shall be payable under subsection (f) to an eligible individual who does not include on the return of tax for the taxable year— (A) such individual’s valid identification number, (B) in the case of a joint return, the valid identification number of such individual’s spouse, and (C) in the case of any qualifying child taken into account under subsection (a)(2), the valid identification number of such qualifying child.
