To change the selection of whether or not you can be claimed as a dependent on someone else's return (i.e. your parent's):

1. From within your TaxAct return (Online or Desktop), click Federal. On smaller devices, click in the upper left-hand corner, then click Federal.
2. Click Basic Information in the Federal Quick Q&A Topics menu to expand, then click Dependent on someone else's tax return.
3. Continue with the interview process to enter all of the appropriate information.
4. On the screen titled Can you be claimed as a dependent?, check I can be claimed as a dependent on someone else's return to remove your exemption (i.e. to indicate you are or will be claimed on someone else's return); or uncheck the box to add back the exemption for yourself, then click Continue.
5. If married, check (or uncheck) My spouse can be claimed as a dependent on someone else's return as needed.

If applicable to your situation, click Filing, then click E-File Return to continue through the e-file steps to resubmit your return.
