“Commissioner'', the commissioner of revenue.

“Eligible taxpayer”, a taxpayer who filed a Massachusetts income tax return for tax year 2019 using an Individual Taxpayer Identification Number (“ITIN”) and who is ineligible for the recovery rebate in section 2201 of the federal CARES act of 2020, the additional 2020 recovery rebates for individuals under the Consolidated Appropriations Act of 2021, or future recovery rebates that congress may authorize; provided that an estate or trust shall not be considered an eligible taxpayer.

“Qualifying child”, an individual listed as a dependent by the taxpayer on Schedule D1 of the Massachusetts income tax return for tax year 2019 who is a child of the taxpayer or a descendant of such a child, or a brother, sister, stepbrother, or stepsister of the taxpayer or a descendant of any such relative, who lived in the same home as the taxpayer for more than half of tax year 2019, who has not provided over one-half of the individual’s own support for the calendar year in which the taxable year of the taxpayer begins, and who has not filed a joint return (other than only for a claim of refund) with the individual’s spouse under section 6013 for the taxable year beginning in the calendar year in which the taxable year of the taxpayer begins, and who had not attained the age of 17 years at the end of 2019.

(b) Notwithstanding any general or special law to the contrary, in the case of an eligible taxpayer, there shall be allowed as a refundable credit against the tax for tax year 2019 an amount equal to the sum of—

(1) $1,800 ($3,600 in the case of an eligible taxpayer filing a joint return), plus

(2) an amount equal to the product of $1,100 multiplied by the number of qualifying children.

(3) future recovery rebates that Congress may authorize that exclude eligible taxpayers.
