Indiana sales tax: flat 7%, nexus & ST-103 filing
Indiana is one of the simplest US sales-tax states — a flat 7.0% rate statewide with no local add-on, SSUTA membership keeping definitions aligned, and INTIME as the single filing portal. The catches: SaaS is exempt but digital downloads are taxable (the same line that bites in NC); the Registered Retail Merchant Certificate renews every 2 years; and use-tax exposure on out-of-state equipment purchases is a routine audit finding.
The Indiana numbers at a glance
| Field | Value |
|---|---|
| Base state rate | 7.0% (flat — no local sales tax) |
| Economic nexus | $100,000 in IN sales (prev or current calendar year) |
| SaaS taxable? | No — remote access exempt |
| Digital downloads taxable? | Yes — under 'specified digital products' since 2008 |
| RRMC renewal | Every 2 years — different from most states |
| Sourcing | Destination (but rate is flat statewide) |
| Marketplace facilitator | $100,000 threshold — facilitator collects, you don't |
SaaS exempt vs digital downloads taxable: the same line as NC
Indiana's framework distinguishes between remote-access services (exempt) and digital products you download (taxable). The DOR's working test mirrors North Carolina's: does the customer end up with a file on their device?
- Exempt: SaaS, cloud storage, streaming subscriptions (you don't keep a copy), online services, cloud computing.
- Taxable: downloaded ebooks, music files, video downloads, downloaded software, ringtones — the customer ends up with a file.
- Bundle problem: a SaaS subscription that bundles downloadable content (a webinar replay, a downloadable PDF report) can become taxable on the whole bundle unless line items are properly separated on the invoice.
HelloBooks tags products at item-master level — remote-access for SaaS, downloadable for digital downloads. The right tax treatment flows automatically.
The 2-year RRMC renewal cycle
Indiana's Registered Retail Merchant Certificate (RRMC) expires every 2 years — different from most states' indefinite registrations. Mechanics:
- RRMC is issued for a 2-year period (e.g., 1 July 2024 to 30 June 2026).
- Renewal is automatic for sellers in good standing (current on all filings and payments). Failure to file or pay can trigger DOR to deny renewal, which means you cannot legally collect.
- INTIME emails reminders 60 days before expiration. HelloBooks also tracks the expiration date in your business settings and surfaces a renewal reminder 30 days ahead.
- Operating with an expired RRMC creates personal liability for the responsible officer for unpaid sales tax collected during the gap — even if you remit on time.
Indiana use tax on out-of-state purchases
Indiana has a parallel 7.0% use tax on tangible personal property and digital products bought from out-of-state vendors when sales tax was not collected. Common triggers:
- Equipment bought from a non-collecting out-of-state vendor
- Software / digital products from non-registered sellers
- Inventory transferred in from an out-of-state warehouse
- Vehicles, boats, aircraft purchased out-of-state and titled in IN
Use tax is reported on the same ST-103 return. HelloBooks tracks out-of-state vendor bills without sales tax, computes the use tax owed at 7%, and rolls it onto the ST-103 automatically.

Frequently asked questions
What is the Indiana sales tax economic nexus threshold?
$100,000 in cumulative gross sales delivered into Indiana during the previous or current calendar year — sales only, no transaction-count test. Indiana dropped the 200-transaction test in 2024. Register with the Indiana Department of Revenue through INTIME and start collecting on the first sale after the threshold-crossing return period.
What is the Indiana sales tax rate?
Indiana is a flat-rate state at 7.0% — no local sales tax at all. Whether you're billing an Indianapolis customer, a Fort Wayne address, or rural Indiana, the rate is 7.0%. This is the simplest US state for rate determination alongside Massachusetts. Indiana is a Streamlined Sales Tax Agreement (SSUTA) member, so registration and definitions align with the multi-state simplification framework.
Does Indiana tax SaaS and digital products?
Indiana does NOT tax SaaS or remotely-accessed software. The Department of Revenue's position is that the customer must take possession of tangible personal property for sales tax to attach; pure remote access doesn't qualify. Downloaded prewritten software is taxable as 'specified digital products' under IC 6-2.5-4-16.4 since 2008. Digital products (ebooks, music, video downloads) are also taxable.
What is Indiana's destination-sourcing rule?
Indiana is destination-sourced — the rate is determined by the buyer's location. But since Indiana has a flat 7.0% rate everywhere, destination doesn't actually matter for rate calculation. Drop-ship and remote sales all use 7.0%. The destination rule still matters for sourcing rules under the SSUTA, just not for the rate itself.
How does the Indiana marketplace facilitator law work?
Indiana requires marketplace facilitators with $100,000+ in Indiana sales to collect and remit on behalf of third-party sellers. Amazon, Etsy, eBay, Walmart, and Shopify Markets in Indiana are facilitators. Sellers still register and file the ST-103, showing marketplace sales as a deduction line. The flat-rate environment makes Indiana the easiest state for marketplace reconciliation.
How often do Indiana sales tax returns get filed?
The DOR assigns frequency by liability: monthly for sellers with monthly liability over $1,000, quarterly for $100-1,000/month, semi-annually for $20-100/month, and annually for under $20/month. Monthly returns on Form ST-103 are due the 20th of the following month or 30th depending on EFT threshold — most monthly filers use the 20th. E-file via INTIME.
What is the use tax obligation in Indiana?
Indiana has a parallel 7.0% use tax on tangible personal property and digital products bought from out-of-state vendors without Indiana sales tax. Common triggers: equipment purchases from non-collecting vendors, software downloads from out-of-state sellers, and inventory transferred in. Use tax is reported on the same ST-103 return.
What are the most common Indiana sales tax mistakes?
(1) Treating downloaded software as exempt — Indiana taxes 'specified digital products' including software downloads since 2008. (2) Forgetting to charge tax on streaming subscriptions and digital products. (3) Missing the 20th-of-month ST-103 deadline. (4) Missing use tax on out-of-state equipment purchases (no IN tax at point of sale means use tax owed on the same ST-103). (5) Treating SaaS subscriptions as taxable — Indiana does NOT tax SaaS access.
