Withholding guide updated with new Idaho W-4
Employers: We’ve updated A Guide to Idaho Income Tax Withholding as of January 7 to include the new 2019 Form ID W-4. Employees should use the Idaho W-4 to calculate their Idaho allowances and any extra state withholding. The form is also available at tax.idaho.gov/w4. We recommend that all employees update their withholding using the Idaho W-4.
No changes have been made to the withholding tables.
