If someone else claimed your dependent already, then your e-filed return will be rejected. Print, sign and mail your own return which claims your dependent. Mailed returns are processed differently by the IRS.
The IRS will contact both parties and sort out who could rightfully claim the dependent. The person who wrongfully claimed the dependent will face repayment of refund $, plus penalties.
When you mail a tax return, you need to sign the return and attach any documents showing tax withheld, such as your W-2’s or any 1099’s.
When you print your return to mail, the first page will tell you what documents to attach and give you the address to mail the return to.
Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.
