In an effort to help protect your identity and fight tax fraud, the IRS and many state tax offices are now asking that tax filers provide their driver’s license or state-issued ID number.
Providing this info is not required to file your Federal taxes. However, in some states, omitting this info may delay the processing of your return.
Please see this TurboTax help article for more information. Normally, it would not matter if your ID was expired for this purpose.
I did not find any reference to ID in the Instructions for Wisconsin Form 1, except that you would need to enter a special Wisconsin Identity Protection PIN, IF you were issued one.
