Get your taxes done using TurboTax

What about creating scenarios?

 

If you are using the Desktop Software there is a What-if worksheet. Go to Forms Mode, click Forms in the upper right (left for Mac). Then click Open Forms box in the top of the column on the left. Open the US listing of forms and towards the bottom find the What-if worksheet.  Or search for "What" and it should find it.

 

What I did is copy column 1 to column 2 and check the Use 2013 rates box.  You can enter your estimated 2013 income, etc.  What I did for state (I have California) I opened the CA Estimated payments worksheet and scrolled down and found a section to enter my 2023 income.
