Hello JPDUNH,
Thank you for reaching out to us with your tax question.
For 2021, if a dependent child such as your teenage daughter earns more than $12,550 of income, she must file a personal income tax return and may owe tax to the IRS. Earned income applies to wages and salaries that your daughter receives as a result of providing services to an employer, even if the job is a part-time job.
Please let me know if you have additional questions. Have a great day! Thank you!
Regards,
Shirleyh88
