After you file

Did you say you could not be claimed as someone else’s dependent, but it turns out your parent(s) can claim you?  Now your parents’ return is being rejected when they e-file, or it will be rejected.  That means your parents must print, sign, and mail their return.  They can still claim you as a dependent, but they cannot e-file now.  

Your part in fixing this is to wait until your return has been fully processed and you have received you refund.  THEN you need to file an amended return, called a 1040X, to change the way you answered that question in Personal Info about whether you can be claimed as someone else’s dependent.  You will have to print and mail the 1040X—it cannot be e-filed. You might need to repay some of your refund.

Note:  The difference is that when you are claimed as someone else's dependent, you lose the $4050 personal exemption, which losers the amount of income you are taxed on.  So any income you received over $6300 is taxable.The person who claimed you gets that exemption, which lowers the amount of income they are taxed on.  It is not a refund.
