For most states, this information is not required in order to efile your taxes, but could help speed up the processing of your return and will not affect your return’s submission. If your state won't accept an efiled return without the State ID/Driver's License, you will have to file the state return by mail.

In an effort to help protect your identity and fight tax Fraud, the IRS and State tax offices are now asking that tax filers provide their driver’s license or state issued ID number. Omitting any of this information may delay return and refund processing.
Some states, however, do require an ID to be provided in order to e-file (e.g. Illinois and Alabama).
For these states (and others) the following website provides information on getting a State-issued ID: DMV.org. Select the License and ID tab, then the Identification cards option from the menu.
For additional information, you can view the IRS information on the New Security Safeguards. or to see if your state is participating, please contact your state revenue agency.
