How can I estimate my wife's tax liability if we file separately?

My (ex)wife and i are getting divorced.  She is insisting on filing separately while I want to file jointly.  

I've already estimated the difference between what I owe if we filed jointly vs. separately (it's about $400 vs. $4,000).  I want to estimate what she would owe, but I don't think I can do this in Turbo Tax.  I want to show her that it's mutually beneficial to file jointly.

Also, she is convinced that if we file separately she won't 'owe' taxes on my unemployment income, which was about $16k last year.  How do I explain to her that this was joint income and it will be factored into her taxes this year for it whether or not we file separately or jointly.



Most couples benefit from filing jointly.

When you file separately, you become ineligible for several deductions and credits.

Also, if one spouse chooses to itemize, then the other spouse must either itemize or forfeit the standard deduction.

Finally, additional rules and complications apply in community property states.

If you want to "model" different tax scenarios, then you should consider switching from TurboTax Online to a desktop version (download or CD-ROM) so you can save different versions of your files.

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.
