All U.S. residents with adjusted gross income up to $75,000 ($150,000 married), who are not a dependent of another taxpayer and have a work eligible social security number, are eligible for the full $1,200 ($2,400 married) rebate. In addition, they are eligible for an additional $500 per child. This is true even for those who have no income, as well as those whose income comes entirely from non-taxable means-tested benefit programs, such as SSI benefits.
For the vast majority of Americans, no action on their part will be required in order to receive a rebate check as IRS will use a taxpayer’s 2019 tax return if filed, or in the alternative their 2018 return. This includes many low-income individuals who file a tax return in order to take advantage of the refundable Earned Income Tax Credit and Child Tax Credit. The rebate amount is reduced by $5 for each $100 that a taxpayer’s income exceeds the phase-out threshold. The amount is completely phased-out for single filers with incomes exceeding $99,000, $146,500 for head of household filers with one child, and $198,000 for joint filers with no children.
