Idaho's Tax Commission recently updated their 1099 and W-2 E-Filing Guides. There are no substantive changes to either guide. The Commission reminds filers that Forms 967 and W-2 are due by January 31, and that 1099s are due by February 28; it is possible to submit Forms 967, W-2, and 1099 simultaneously on or before January 31.
