Starting a service business in Indiana comes down to four things: picking a structure, registering with the state, getting licensed for your trade, and setting up a way to bill customers. Filing an LLC in IN costs $95, ongoing reporting is $31 biennially, sales tax is 7%, and personal income tax runs 3.05% flat. Below is the full sequence, the fees you should budget for, the licenses most trades need, and the deadlines that catch new Indiana owners off guard.
Most new registrations come out of Indianapolis, Fort Wayne, Evansville and the rest of Indiana — local business licenses are issued at the city or county level, so check yours after the state filing clears.

Online LLC filings with the IN Secretary of State are typically processed in a few business days, and an EIN from the IRS is issued immediately online. Trade licensing and local permits usually take longest — plan on two to six weeks before you're fully cleared to work, depending on your trade.
No — you can operate as a sole proprietor in Indiana and still invoice customers legally. An LLC ($95 to file, $31 biennially) separates your personal assets from business liability, which matters most once you're on customer property, hiring help, or signing contracts.
Indiana sales tax is 7%. Materials and goods are commonly taxable, while labor treatment depends on the type of work, so bill parts and labor as separate lines and register with the Indiana Department of Revenue before you start collecting.
