Filing fees
Indiana does not publish its statutory filing fees on a standalone HTML fee schedule page. The official fee calculator at inbiz.in.gov — Fee Calculator generates exact totals for any filing type: select Secretary of State as the agency, choose a transaction type, then select the entity type and filing type. Use this calculator before submitting any filing. One component of Indiana's fees is publicly documented: Enhanced Access fees, set by the Secretary of State under IC 4-5-10-2 and confirmed unchanged in a 2025 SOS regulatory filing. These are charged in addition to statutory filing fees for online transactions. The same regulatory analysis states Indiana ranks among the 10% lowest-cost states nationally for business registration, with Enhanced Access fees unchanged for over ten years.

HB 1593 and HB 1666 filing changes (effective January 1, 2026)
Two 2025 Indiana laws changed business entity filing requirements. HB 1593 requires anyone submitting a filing on behalf of another person to take reasonable steps to verify that person's identity, sets new disclosure and eligibility rules for Commercial Mail Receiving Agency (CMRA) addresses used on filings, lets remote-only businesses exclude a residential address from the public record, and allows reinstatement of entities dissolved more than 5 years if the filer submits a notarized affidavit explaining the request. HB 1666 requires "health care entities" (as newly defined in IC 23-0.5-2-12.5) to report certain ownership information on their business entity report. Identification documents themselves are not filed with the SOS but must be retained and provided to the office on request.
UCC filing, notary, and apostille services
The Secretary of State also handles UCC filings, notary commissions, and document authentication through INBiz:
- UCC search and filing — $5 per UCC information request.
- Notary public commissions — a $75 non-refundable application fee plus a $16.32 state police background check; an 8-year term requires a $25,000 surety bond.
- Apostilles and authentications — $2 per document (adoption, vital-record, transcript, and SOS-issued documents are exempt).
