The Indiana voluntary disclosure agreement.

Indiana, in brief.
What is the economic nexus threshold in Indiana?
$100,000 in sales, effective October 1, 2018. The 200-transaction threshold was repealed effective January 1, 2024. Once the threshold is crossed, remote sellers must register with the Indiana Department of Revenue and begin collecting.
What is the sales tax rate in Indiana?
The state sales tax rate is 7%. No local sales taxes.
Do marketplace facilitators collect Indiana sales tax?
Yes — marketplace facilitators have been required to collect since July 1, 2019. Direct (non-marketplace) sales remain the seller’s obligation.
How does a remote seller register for Indiana sales tax?
Register with the Indiana Department of Revenue before collecting — a remote seller must register once it crosses the economic nexus threshold ($100,000 in sales). As a Streamlined Sales Tax member state, Indiana also accepts central registration through the SST system, which covers all member states in one application.
Does Indiana offer a voluntary disclosure agreement (VDA)?
Yes — the Indiana Department of Revenue administers a voluntary disclosure program with a lookback of 36 months (3 years). Penalties are generally waived; interest is generally still due. An advisor can approach the state anonymously before disclosing the client’s identity.
