Form Your Indiana LLC
Launch your Indiana limited liability company through the Indiana Secretary of State's INBiz portal. Indiana charges $95 for online filing (or $100 by mail), with standard processing in 5-7 business days. Indiana's Business Flexibility Act provides robust member protections and flexible operating agreement provisions.
Why Indiana Works for LLCs
Indiana's business environment offers a compelling combination for LLC owners:
- Low flat income tax (2.95%) — One of the lowest flat rates in the country, declining from 3.15% in prior years per scheduled reductions
- Biennial reporting — Business Entity Reports are due only every 2 years ($32 online), not annually like most states
- No franchise tax — Unlike Texas, California, or Tennessee, Indiana imposes no entity-level tax on LLCs
- County income taxes — An additional 1%-3.38% varies by county (factor this into your tax planning)
- Efficient online portal — INBiz (inbiz.in.gov) handles formation, reports, and all filings electronically
- Low ongoing cost — $32 every two years is among the cheapest maintenance schedules nationally
Indiana's economy supports diverse LLC formation: manufacturing (automotive, steel, pharmaceuticals), agriculture, logistics and distribution (crossroads of I-65, I-69, I-70), healthcare, motorsports (Indianapolis Motor Speedway ecosystem), and life sciences (Eli Lilly, Cook Medical corridor).

Complete LLC Formation Guide
Our step-by-step formation guide walks you through every requirement — from searching Indiana's business name database to filing your Articles of Organization through the INBiz portal at inbiz.in.gov. Indiana's online system processes filings quickly, typically 5-7 business days.
After You're Formed
Once the Secretary of State approves your Articles of Organization, there are ongoing compliance requirements to maintain good standing. Indiana's biennial Business Entity Report costs $32 and is due in your "birth month" (registration anniversary month) every two years. Missing the deadline leads to administrative dissolution under the Indiana Business Flexibility Act.
