Indiana at a glance
What makes Indiana different
- Indiana's "Annual Report" is actually a BIENNIAL Business Entity Report (BER) filed every TWO years, not annually. One of the few US states with biennial frequency (alongside NY, AK, IA, NE). Effectively cuts SOS compliance burden in half.
- BER due in anniversary month, every 2 years. Entity formed June 2024 → first BER due June 2026, then June 2028, etc.
- LLC BER fee: $50 (according to IN SoS). Paid every 2 years = effectively $25/year amortized. Among lower US AR rates when annualized.
- Corp BER fee: $30 online / $50 paper. Nonprofit Corp BER $20.
- Formation fees: LLC $95 online / $100 paper. Corp $90 online / $100 paper. Indiana uses Enhanced Access (EA) surcharge of $20 added to the statutory base fee. Online filings effectively the same as paper minus the paper-handling premium.
- Filed at Indiana SoS Business Services Division (standard SOS structure, unlike MD/VA/MI/AZ/WI).
- INBiz portal processes online filings same-day to 1 business day. Among fastest US.
- Personal Income Tax 3.05% flat (2024-2025), scheduled to drop to 2.9% by 2027 under SB 1 of 2023 trigger formula.

Common questions.
What is the first step to start a business in Indiana?
The first real decision is your entity type, because it drives everything after: taxes, liability, and paperwork. For most small businesses in Indiana that means forming an LLC, which you do by filing a formation document with the state and naming a registered agent. Get the structure right first, then EIN, banking, and licenses follow in order. We walk you through the Indiana sequence so nothing is done out of turn.
Which business structure should I choose in Indiana?
Most Indiana founders land on an LLC for its liability protection and simple pass-through taxes, but a corporation makes sense if you plan to raise venture capital or issue stock. A sole proprietorship is simplest but leaves your personal assets exposed. The honest answer depends on your goals, so we lay out the LLC-versus-corporation trade-offs for Indiana rather than pushing one.
Do I need a registered agent in Indiana?
Yes. Indiana requires every LLC and corporation to name a registered agent with a physical in-state address to receive legal and state notices. You can be your own, but then your address is public and you must be available during business hours. Most owners use a service to stay private and never miss a notice. We include agent service so this box is checked from day one.
How much does it cost to start an LLC in Indiana?
The cost is the Indiana state filing fee plus any service you use, and Indiana also charges recurring fees such as an annual or biennial report. Our formation service itself is free, and we pass state fees through at cost with no markup. Because state figures change over time, current Indiana amounts are on the pricing page rather than quoted here where they could go stale.
What taxes will my Indiana business pay?
It depends on your structure and activity, but expect some mix of federal income and self-employment tax, Indiana state taxes where they apply, and sales tax if you sell taxable goods. Some states have no income tax while others add franchise or gross-receipts taxes. Once profits grow, an S-corp election can reduce self-employment tax. We flag which Indiana taxes actually apply to you rather than listing every possibility.
Do I need an EIN for my Indiana business?
Almost certainly. You need an EIN to open a business bank account, hire employees, or file most business taxes, and it keeps your Social Security number off company paperwork. It is free from the IRS, and our value is getting it right and fast, including for founders without an SSN. We obtain it as part of setting up your Indiana entity so banking is not held up.
What are the ongoing compliance requirements in Indiana?
After formation, Indiana expects you to keep a registered agent, file the periodic annual or biennial report, pay any state fees, and renew licenses on schedule. Miss these and the state can revoke your good standing or dissolve the entity. We track your Indiana deadlines in a compliance calendar and can file the reports for you so nothing lapses while you run the business.
