Is there a minimum amount I don't have to report as income?

Any money you earn caring for children is taxable income, no matter how small the amount. If a parent pays you $15 for one day of care and you never see the parent again, you must report the $15 (or even $1) as income on Schedule C.Parent may or may not try to claim the child care tax credit. If they don't, you still must report what they did pay you as income.
