Register with the Department of Revenue online using your INBiz account:

  2. At the bottom of the page click Register Now and follow the instructions online to get your business registered for a Withholding Account.
  3. You should receive your Withholding Account number in about 2-3 days by email. Please keep this time frame in mind when planning your first payroll.
    • You will receive a 10-digit Taxpayer ID as well as a 3-digit location code. If there is only one location, most employers will have a location code of 001. If you have a consolidated account, you'll usually have a location code of 900.
      • Please contact the agency at (317) 232-2240 if you have not received or need to verify your location code.

Indiana Form WH-4

Form WH-4 will help Gusto determine how much state income tax needs to be withheld from your employees. This form is also used by Indiana to determine county taxes for the entire year. 

Indiana uses an employee's location as of January 1st to determine applicable taxes for the entire year. As a payroll administrator of a company that has a location in Indiana, you'll want to verify that this information is correct in Gusto prior to running your first payroll of the year. 

If an employee is planning on moving on or before January 1st, you will need to update their address in Gusto. If they are moving after January 1st, you should continue to use their original address. If the address has in fact changed, the employee will see their prior Indiana county tax on their paystubs for the remainder of that year.
