In 2017, the Internal Revenue Service (IRS) expanded its Child Tax Credit to include a tax credit of up to $500 for “other dependents,” a group that can consist of people who are tended to by a caregiver. If you paid more than half of the expenses for someone living with you who made less than $4,300 in gross income (in the 2021 tax year), even assisting non-relatives can qualify you for this credit.
