I need to change my sons dependant status to yes he can be claimed on some one else's tax return

How to change it

[DoninGA]

If the return has been filed and accepted by the IRS then the return will have to be amended to change the dependency status.

If the return has not been filed, then click on My Info and change his status.

If you are using TurboTax Online and haven't yet filed the return:

1. Open your return
2. From the left column, choose My Info
3. In the My Info section, you can update information about your dependents, and delete or add dependents. This information is used by the program to calculate the amount of any Child and Other Dependent Tax Credits to which you may be entitled.

See this tax tips article for information about the rules for claiming dependents.

As @DoninGA stated, if you already filed your 2025 return, you would need to amend it to make a change. You'd need to wait until any refund is issued or additional tax payment processed to amend the return. In addition, the Form 1040-X for amending a Federal return is currently expected to be available on or about February 18, 2026.
