During the study period, the eligibility threshold for the increased rebate was raised from 300% to 400% of the federal poverty level (FPL). Approximately 7,300 additional recipients with incomes between 300% and 400% for the FPL received an increased rebate, constituting 36% of increased rebates issued during the study period. Notably, it was found that 15% of recipients with household incomes at or below 300% of FPL and slightly over 20% of those in the 300–400% FPL range qualified for increased rebates but did not claim them.

Other characteristics examined across income levels include gender, race, ethnicity, tax filing status, household size, and the category of the vehicle receiving a rebate. The results revealed that gender identity, vehicle category, and vehicle type were distributed similarly across all income levels and between the two rebate types.

Consumer characteristics by income levels, gender identity, vehicle category, and vehicle type exhibited similar distributions for both rebate types. However, variations were observed in other metrics. Increased rebate recipients displayed greater racial diversity compared to standard rebate recipients. Additionally, there were slightly higher rates of joint tax filers across income levels. Furthermore, fewer increased rebate recipients reported residing in Disadvantaged or Low-Income Communities.
