Recovery rebate not generating for new dependent in 2021 despite adding new dependent and correctly checking all information (living with me full time, etc.).

You may not qualify for the Recovery Rebate Credit if your adjusted gross income (AGI) exceeds:

• $160,000 if married and filing a joint return or if filing as a qualifying widow or widower
• $120,000 if filing as head of household or
• $80,000 for eligible individuals using other filing statuses, such as single filers and married people filing separate returns.

The new dependent must be a qualifying child.   See this IRS FAQ.

A child is your qualifying child if the following conditions are met:

• Relationship to the individual who’s eligible for the payment: The child is your son, daughter, stepchild, eligible foster child, brother, sister, stepbrother, stepsister, half-brother, half-sister, or a descendant of any of them (for example, grandchild, niece, or nephew).

  • under age 19 at the end of the tax year,
