My son is 16 and he worked made over 10k can i add his w2 to my return or does he file on his own

[DoninGA]

He files his own tax return to get the taxes withheld refunded.  He has to enter on his tax return that he can be claimed as a dependent.

If your son has income in 2024, you don't report your son's income on your tax return.

You can still claim him as a dependent if he didn't provide more than half of his own support for the year and he was under 19 at the end of 2024 (or under 24 and a full-time student).

If he was 19 or older (or 24 or older and a full-time student), you can't claim him as a dependent if he earned more than $5,050 in 2024.

If it has to be reported, at all, it goes on his own return. If your dependent son is under age 19 (or under 24 and a full-time student), he must file a tax return for 2024 if he had any of the following:

1. Total income (wages, salaries, taxable scholarship etc.) of more than $14,600 in 2024.
2. Unearned income (interest, dividends, capital gains) of more than $1,300.
3. Gross income (earned plus unearned) exceeding the larger of $1,300 or his earned income (up to $14,600) plus $400.
4. Other self-employment income over $400, including box 1 of a 1099-NEC

If your dependent son files his own return, he has to indicate in the My Info section of TurboTax that he can be claimed as a dependent by another taxpayer.

Even if he had less, he can file if he needs to get back income tax withholding. He can't get back Social Security or Medicare tax withholding.

Ok do I have to wait to file mine or I’ll be okay to file mine and he files once he gets his w2

[Opus 17]

A child's income from working is never added to a parent's return, the child must file separately.  This usually does not affect whether or not they can be claimed as a dependent.

The only time a child's income can be added to a parent's tax return is if the income is only interest or dividends less than $13,000.  If the child has income from any other source, then all their income is reported on a return in their own name.

You can file your tax return now and claim him as a dependent.

He can file later.
