After you file

Please follow the directions below to create test returns, for each of you. However, make sure you prepare the state returns also so you can get a complete tax picture.

There's also a quick way to get a comparison on the federal return for a joint return prepared in the TurboTax CD/Download software. (This won't work in the online versions, as forms mode isn't supported).

  1. Open your return and select Forms in the top right corner of the window.
  2. Click Open Form and type What-If Worksheet (it may appear as What-If Wks).
  3. Check the MFJ vs. MFS box at the top.
  4. Scroll down to Balance Due (Refund) located under Line 74.
  5. The second column shows the federal outcome for a joint return, and the third and fourth columns, respectively, show the outcome for the taxpayer and spouse if filing separately.
  6. Negative numbers are refunds, positive numbers are taxes due.

However, this doesn't give you the whole picture because it doesn't account for your state taxes. For a true apples-to-apples comparison, you'll need to create test returns.
