What is a Tax ID?
Indiana’s Tax ID number identifies a business for tax purposes. The ID is called an Employer Identification Number (EIN). An EIN has 9 digits and is assigned by the IRS. Businesses need an EIN to file taxes, open bank accounts, and apply for business loans. In Indiana, most businesses require a federal Tax ID number.
Applying for an EIN is free, and the EIN stays with the business for life. Another ID is Indiana’s state Tax ID, which is issued by Indiana’s Department of Revenue. Businesses may need both a federal EIN and a state Tax ID.
Obtaining a Tax ID
There are several ways to apply for a Tax ID in Indiana, with online applications being the quickest, typically taking 1-2 days. Applying by phone, mail, or fax takes 4 weeks or more.
Setting up a business in Indiana includes choosing a legal structure, registering the business, obtaining necessary licenses or permits, and then getting an EIN and registering for state, local, and federal taxes.
