My dad filed me as an dependent, even though I am not...

[Mochii_]

I(20M) used to live at the same house with my dad in 2022, the rent was being shared by 2 families which is our and my aunts (we rented a big house and lived together because it is easier to take care of our grandma). Everyone was paying their part of the rent (including me) so I was able to write a portion of it (used as an office) along with many other work-related stuff off because I am a dependent contractor. I just found out through my aunt that he filed me as his dependent, does that effect the ability to write off my expenses or increase my taxes? If yes then how do I get myself out of this situation? (This is probably not necessary but yes I made 3,4x his yearly $).

If your father already filed a tax return claiming you as a dependent, you are not going to be able to e-file this year.   Once your SSN has been put into the system it will take months to correct that.   When you file your tax return you will have to file by mail.   And...if you were not a full time student, and you earned over $4400 for 2022, no one can claim you as a dependent, so Dad will have to amend his tax return to remove you as a dependent.  You do not have to wait for him to do that---you can go ahead and mail in your own tax return. ( If you were a full-time student in 2022, that changes things---and Dad can claim you---so post back if that is the case.   If you were a full-time student, you must say on your own return that someone else can claim you.)

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.

Federal and state returns must be in separate envelopes and they are mailed to different addresses.  Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
