Can I claim my dependent’s income if under $4700 on my taxes
Only a taxpayer and their spouse (if applicable) will need to claim income on a return. Do not claim your dependent's income on your return, even if it's under a certain amount.
Check the IRS site below to see if your dependent even needs to file at all.
