Each state has its own requirements regarding taxpayer and spouse identification included in electronically filed tax returns, whether a driver's license or other state-issued ID.
Depending on the state, not including the state ID may prevent e-file or could potentially delay processing the return. Including the ID is optional in most states, and if provided the state will use the information to facilitate investigating identity theft.
Note: Returns utilizing a bank product to facilitate the refund must have an ID included in the return.
