Can I claim my son as a dependent if he claims himself on his tax return?

    He cannot be your dependent and also take a personal exemption on his own return.  If he CAN be claimed as a dependent on your return, he must so indicate this on his return and would not be allowed the personal exemption.  It doesn't matter if you actually claim him, only that you (or someone else) can.
    • My question is related.  My son indicated he could not be claimed on another return.  He submitted his return in Feb and got a refund.  I went to submit my joint return last week and it was rejected - most likely for this reason.  My question is next steps.  I filed for an extention.  Do I need to have my son amend his 2011 return first then send mine in?  Can I do this at the same time?   FInamcially, it's better for him to pay the tax due than for me to loose the decution.  We provided over half his support in 2011 (through August) so we should be entitled to claim him.  Just didn't coorindate this too to well with him;-)
    You can mail your return in now.  You won't be able to efile even when he amends his return.  An amended return will take too long to process and clear the exemption.

    Read this on how to amend a 2011 return….  

    The amended return is form 1040X and can only be mailed (not efiled) and will take 8-12 weeks or more to process.  And they only send checks for amended returns, no direct deposit.  You should also wait to amend your return until you get your original refund or your payment has cleared because the IRS might adjust your original return.

      People come to TurboTax AnswerXchange for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:

      1. Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
      2. Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
      3. Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
      4. Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
      5. Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
