The Department of Revenue (DOR) has partnered with the Secretary of State and Department of Workforce to create a streamlined and expedited process to help register and manage business needs. INBiz is a one-stop portal that allows you to register your new business with all three state agencies.
Registration is required for all tax types applicable to your business including Indiana retail sales, withholding, out-of-state sales, gasoline use taxes and metered pump sales, tire fees, fuel taxes, wireless prepaid fees, food and beverage taxes, county innkeeper's taxes, heavy vehicle rental tax and motor vehicle rental taxes. ALL businesses in Indiana must file and pay their sales and withholding taxes electronically.
You can now file, pay, and manage all your Indiana business tax obligations 24/7 using DOR’s e-service portal, the Indiana Taxpayer Information Management Engine or INTIME.
