Filing guidance
Idaho residents must file their state income tax returns by the same deadline as federal taxes, typically April 15th. Because Idaho uses a flat tax, many residents find the state return to be significantly easier to complete than the federal 1040. Ensure you have your W-2 forms ready, as these will clearly state your Idaho wages and the total state income tax withheld throughout the year. If you have questions regarding specific credits, the Idaho State Tax Commission provides comprehensive instructions through their official website to guide you through the process.
