If someone claims me as a dependent will it affect me when I file my taxes or for any stimulus checks in the future.
If you were under the age of 19 on Dec 31 of the tax year and a few other criteria are met then your parents qualify to claim you as a dependent, regardless of how much money you may have earned during the year.
