Lack of Data - Joint Tax Return

[rmurbach]

I'm married, and we file jointly. Turbo Tax does not tell me which spouse paid their equal share in federal and state taxes.  In other words, my wife had two additional part-time jobs. Thus she had more income, but did she pay the right amount of tax on her part? I don't know if I paid my full amount based on my income alone vs. my spouse's income. Turbo tax does not give me the breakdown saying - Husband earned this income and paid this tax. Spouse earned this income and paid this tax. When filing jointly, everything is lumped together. I can't tell if the tax owes was because of me or my spouse.

Multiply your marginal tax rate by your separate incomes for your separate tax liabilities and then subtract each of your withholding.

Thanks for your response. Our MTR is 24%, while our ETR is 17.11%. Investopedia states, "The effective tax rate is a more accurate representation of a person's or corporation's overall tax liability than their marginal tax rate, and it is typically lower. When considering a marginal versus an effective tax rate, bear in mind that the marginal tax rate refers to the highest tax bracket into which their income falls." Is MTR still the right calculation we should use?

You could do it either way since you would be applying the same percentage to each of you. Would be interesting to do it both ways.
