Can I itemize for Wisconsin if I take the standard for the Federal?

[JohnW15 · Accepted solution]

Yes, you can.

According to "Line 20, Itemized Deduction Credit" on page 31 of Wisconsin's Form 1 Instructions,

"If you did not itemize deductions for federal tax purposes, use the amounts which would be deductible if you had itemized deductions. To determine the amounts to use, complete a federal Schedule A. Write “Wisconsin” at the top of this Schedule A and enclose it with your Form 1."

Some exceptions apply, so please see the link I've provided above for more information.

How do I do this with Turbo Tax?

You should input any deductions you have into your federal return, and any of these that are also valid for your state return will populate on your state return.  (You'll still have the option to take the standard deduction on your federal return after you've input these deductions, if that's what you want.)
Then, go through your state tax program from the beginning. Look for a screen that asks which deduction you want to take. The exact placement of this screen varies by state, but most likely you'll find it at the beginning of the interview or right before the deductions section.
