If you CAN be claimed as someone else's dependent and you answer incorrectly on your own tax return and say you cannot be claimed-----yes, it can cause problems. How big the problem is depends on who files first.
If the person who can claim you filed already, then your own e-file will be rejected and you will have to fix it and re-file your own tax return.
If you can be claimed as a dependent and you answer the question in My Info incorrectly, here is what happens if you e-file first: Your Social Security number goes into the IRS system as having been used. When your parents try to e-file, their e-file is rejected and they will find it impossible to e-file their own tax return. Then they will have to print, sign and mail their return and wait for months for it to be processed. You, meanwhile, will have to file an amended tax return on a special form called a 1040X, which also takes months for the IRS to process. So make sure you know the correct answer to "Can anyone claim you as a dependent on their tax return?"
