Why is this important?
For employers who pay employees in Indiana, use this guide to learn what’s required to start running payroll while keeping compliant with state payroll tax regulations. Without this information, OnPay will be unable to file or deposit any Indiana tax payments for your company. Any penalties and interest that accrue from missed tax payments will be your company’s responsibility.

Where you can find the tax account numbers needed
If you are an existing employer who has previously run payroll in Indiana, you likely already have the IDs and online accounts needed for OnPay to process your tax filings.
If you are a new employer in Indiana, you will need to register your business with the Indiana Department of Revenue and Indiana Department of Workforce Development. This must be completed for OnPay to be able to file and pay your Indiana taxes.
Indiana Tax ID Number
Existing Indiana Employer:
- You can find your Indiana Tax ID number on notices received from the Indiana Department of Revenue.
- If you cannot locate this number, please call the agency at (317)-233-4016.
New Indiana Employer: Register with the Indiana Department of Revenue
- Register online with the Indiana Department of Revenue on INBiz.
- You will receive your Tax ID within a few hours of completing the online registration.
Unemployment Account Number and Tax Rate
Existing Indiana Employer:
- You can find your SUTA Account Number and Tax Rate by logging into your Indiana Uplink account, or on any previously filed quarterly contribution and payroll report.
- Your Unemployment Tax Rate can also be found on the annual Merit Rate Notice mailed to you by the Department of Workforce Development.
- If you cannot find these numbers, contact the agency at (800) 891-6499.
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.
