My son earned $14K last summer and is required to file his own returns w/ Standard Deduction. As parent can I claim him as dependent on my returns? I paid all his expense

If he is under the age of 19 you can claim him as a dependent under the Qualifying Child rules if he meets the requirements.  Or if he age 19 or older and under the age of 24 and a full time student he can also be claimed under the Qualifying Child rules.

To be a Qualifying Child -

1. The child must be your son, daughter, stepchild, foster child, brother, sister, half brother, half sister, stepbrother, stepsister, or a descendant of any of them.
2. The child must be (a) under age 19 at the end of the year, (b) under age 24 at the end of the year and a full-time student or (c) any age and permanently and totally disabled.
3. The child must have lived with you for more than half of the year. Temporary absences while away at college are considered living with you.
4. The child must not have provided more than half of his or her own support for the year.
5. If the child meets the rules to be a qualifying child of more than one person, you must be the person entitled to claim the child as a qualifying child.
6. The child must be a U.S. citizen or U.S., Canada or Mexico resident for some portion of the year.
7. The child must be younger than you unless disabled.

@jun1wang -  maybe yes and maybe no.

if he is a full time student under the age of 24 and he lived with you for at least 6 months of the year, you are probably okay to claim him as a dependent.  Read @DoninGA s details of a "qualifying child'.  He must check the 'I can be claimed by someone else' box on his tax return.

however, if your child was no longer in school, then he made too much to be claimed as a dependent.  Once his income exceeds $4400 (I think that rises to $4700 in 2023), he is no longer eligible to be a dependent.
