Register for Unemployment Insurance Account
Entities are liable for UI premiums under SUTA and are considered an employer if the entity has liability to pay one dollar ($1) or more in remuneration to a covered worker. It must register with the Indiana Department of Workforce Development (DWD) during the first quarter it is liable to report wages.
Please note that the organization should provide both a mailing address and a physical address where the work is performed in Indiana if those are not the same.
Do not wait until the first report is due to start the registration process.
If you can't register online you can register by completing State Form 2837 (SUTA Account Number Application and Disclosure form). Please be aware that filing a paper registration form can significantly delay the registration process.
You may also obtain the form by calling DWD at (800) 891-6499 and selecting the employer tax option.
