The state Department of Revenue says those filing Forms 40, 40-A and 40 NR should include their driver's license number or non-driver's license number and their date of birth.
State Revenue Commissioner Julie P. Magee said the additional information is for protection against identity theft and fraudulent tax returns. She claims the information can be validated quickly and it will not affect the normal processing of a tax return.
The Internal Revenue Service does not require driver's license numbers for Federal returns. Instead, personal identification numbers are used to protect those filers that have fallen victim to identity theft.
