If married filing separately, do I enter half my W2 and half of my husband's on my return and he on his?

[SherekaB]

No. If you file married filing separately all his income and information would go on his own personal return. All your income and information would go on your return. The only information of his that you would include on your return is his name and social security number.

Most married couples benefit filing Jointly since the tax rate is lower and you do not forfeit your deductions and credits. In order to file Jointly you need to choose which account you would like to work in if you both have TurboTax accounts.  Go to the Personal Info section and select Married as your marital status. The program will then ask if you would like to file with your spouse. Select Yes. You will then be able to input any information that your spouse has.

This does not account for if you are in a community property state.  In which case you need split the income according to community property state laws.
