In the Research Letter titled “Association of Tax Preparation Service in a Pediatric Clinic With Increased Receipt of The Child Tax Credit,” which published online March 21, 2022, there were errors in the Introduction and Results sections. The third sentence of the Introduction incorrectly stated the percentage of eligible recipients who may be prevented from receiving the Child Tax Credit. The sentence should be “However, tax filing barriers (eg, parents who are not US citizens and lack internet access or technological devices) may prevent 2.3 to 5 million children from receiving the CTC.” The last sentence of the Results section incorrectly stated that the analysis was adjusted for race and ethnicity. The analysis was adjusted for race, sex, and age, not ethnicity. This article was corrected online.
