Indiana payroll tax and registration guide

Why is this important?

The following information requests and registration instructions must be completed before you can use OnPay to run payroll. To maintain compliance with state payroll tax regulations, you will need to provide: 

• Your state Employer Identification Number and state tax IDs - You must be registered with all state and local agencies listed in this article
• Tax rates - State and local tax offices determine these rates based on the type, age, and size of your business
• TPA and power of attorney - Most tax offices require this before we can submit quarterly wage reports and deposits on your behalf

This information must be provided and maintained by you in order for OnPay to accurately file and deposit tax payments for your company. OnPay is not responsible for any penalties or interest that incur due to missing or incorrect company tax information.

Note: Each state has its own requirements, so if you pay employees in more than one state, you’ll find separate tax guides for each state.

New Indiana Employer: Register with the Indiana Department of Workforce Development

• Register online with the Indiana Department of Workforce Development.
• You'll receive your account number and tax rate instantly once you have completed the online registration.
• Unemployment tax rates are determined annually on June 30th, and apply to the following calendar year. Most new employers are assessed a rate of 2.5% for the first four calendar years that they operate in Indiana. Note: Governmental entities, construction companies, and successor employers have different new employer rates. The state's unemployment wage base is $9,500.
  • The new employer rate for governmental entities, not electing to be reimbursing as discussed in Section II, is 1.6%.
  • New successor employers will inherit the rate of their predecessor. So a new successor employer rate can range from 0.50% to 7.4% under the current rate schedules.

 If you are unsure about your rate, contact the UI agency at (800) 891-6499 (Monday-Friday: 8:00 AM to 4:30 PM Eastern).

Paying employees in other states?

If you operate in multiple states or just have employees working from home across a state line, it's important to file the correct state forms for those workers. See what forms we file in the states where you pay employees.
