INCOME TAX WITHHOLDING (ITW)

Return to Questions

 

ITW - 1	Do I need an Idaho withholding account number? You must have an Idaho withholding account number if you have one or more full or part-time employees in Idaho and the IRS requires you to issue W-2 Wage and Tax Statements. This applies to all employers, including agricultural and domestic employers.  An out-of-state employer who has no employees working in Idaho can voluntarily withhold Idaho income tax for an employee with an Idaho filing requirement.  However, the employer must have an Idaho account and pay the withheld tax on time. For more information see A Guide to Idaho Income Tax Withholding. Ref:   Idaho Code Sections 63-3035 and 63-3036 Ref:   Idaho Income Tax Administrative Rule 870 Contact us if you need more information. Return to Questions
ITW - 2	How do I get a withholding account number? To apply for an Idaho withholding account, register online at business.idaho.gov or complete the IBR-1 (Idaho Business Registration Form), which you can also get from any Tax Commission office. When completing the application, use the same employer name and federal employer identification number (EIN) you will use to prepare your employees' W-2s. The Idaho withholding account number is not transferable. If your EIN changes, you must complete a new application. If your business name changes, please notify the Tax Commission. Contact us if you need more information. Return to Questions
ITW - 3	If I have an employee who is an Idaho resident, but is working in another state, do I need to withhold Idaho income tax? No. Generally, you should withhold tax for the state in which the employee is working. You should contact that state to be sure of its withholding tax laws. If the other state doesn't require withholding, Idaho tax can be withheld if both you and your employee agree. Contact us if you need more information. Return to Questions
ITW - 4	Is a company in another state required to withhold Idaho income tax from an employee working in Idaho? The employer must withhold Idaho income tax if the employee is physically working in Idaho. If the employee is a nonresident and earns more than $1,000 in Idaho in one year, the employer is required to withhold Idaho income tax. The employer must have a permit and report the wages to Idaho. If the employee is not a resident of Idaho and earns gross income of more than $2,500 from Idaho sources, he is required to file an Idaho income tax return. For more information, see A Guide to Idaho Income Tax Withholding (available for download as three PDFs from our Publications page). If the employee isn't physically working in Idaho, the employer doesn't have to withhold Idaho income tax. However, if the employee lives in Idaho and wants to have Idaho income tax withheld, the employer can get a permit and withhold as a convenience to the employee. Contact us if you need more information. Return to Questions
ITW - 5	Where do I find a copy of the Idaho Employee's Withholding Allowance Certificate? Idaho doesn't have its own Employee's Withholding Allowance Certificate. Use the federal Form W-4 for Idaho employees. Employee allowances can be equal to, or less than the federal. If the state allowances are less, you can note that on the federal W-4 or use another federal W-4 and identify it as the state copy. Contact us if you need more information. Return to Questions
