Indiana EIN Number: INBiz, Your TID and the SUTA Account

After your EIN in Indiana

INBiz is Indiana's one-stop portal for registering with the Department of Revenue, the Secretary of State and the Department of Workforce Development, and the Department of Revenue's Business Tax Application (BT-1) is completed there. For the SUTA account, the Department of Workforce Development sends new employers to Uplink Employer Self Service.

Indiana's unemployment account is separate from the Department of Revenue's Taxpayer ID. The Department of Workforce Development issues its own SUTA account number through Uplink Employer Self Service, and tells employers to start that registration after the first Indiana payroll has been issued.

Indiana's Department of Revenue recommends INBiz for new businesses because it reaches DOR, the Secretary of State and the Department of Workforce Development in one place. Registering directly in INTIME, which sole proprietors may do, opens accounts with DOR only.

Employers withhold county income tax along with state income tax, at rates set for each of Indiana's 92 counties.

Also on the Indiana list

• Register with the Indiana Department of Revenue through INBiz for the tax types the business needs. DOR then issues an Indiana Taxpayer Identification Number, and an LLC that makes retail sales also receives a Registered Retail Merchant Certificate for each retail location.
• File the Business Entity Report with the Secretary of State through INBiz every other year, by the end of the month in which the LLC was formed.

What is different about Indiana

• Indiana's Business Entity Report is biennial and is keyed to the month the LLC was formed, not a single statewide deadline. The report is past due after the end of that month in the reporting year, and the due date is shown on the company's record in the INBiz business search under its business ID.
• The Indiana Department of Revenue identifies a business by its own ten-digit Taxpayer Identification Number, plus a three-digit location number for each location. Several locations under one EIN can be consolidated under one TID, but separate companies with separate EINs cannot share one, and a change that produces a new EIN requires a new state registration.
• Indiana employers withhold county income tax as well as state income tax, at rates set for each of Indiana's 92 counties. Each employee's county is fixed as of January 1 on Form WH-4, the Employee's Withholding Exemption and County Status Certificate, and a move later in the year does not change it until the next calendar year.

Before you apply

The SS-4 must match the Indiana Secretary of State filing; its business ID is a state index, not a tax ID.
