How can I identify in a jointly file the tax portion of each individual?

Dear all,

 

I am filling the taxes with my spouse. I work in a company (I received the W-2 form), and she is self-employed (we file Schedule C). We need to file jointly, but we would like to know the tax portion of each one individually. Do you know if there is a way to find these figures without filling separately?

 

Thank you.
