How the numbers shift across typical situations for this calculator:
| Scenario | Sales tax | Total (purchase + tax) |
|---|---|---|
| $100 purchase (7.00%) | $7.00 | $107.00 |

How This Calculator Works
Indiana's flat 7% statewide rate is among the highest single-rate states with no local add-on. The absence of local sales tax is unusual for a state of Indiana's size — most peer states (Ohio, Michigan, Illinois) have some local layer. Indiana funds local governments through property tax, income tax (a county-option income tax exists), and motor-fuel tax instead. Indianapolis Motor Speedway hosts the Indy 500 every May; the Statehouse in Indianapolis has the only stained-glass dome in any U.S. state capitol. Hoosier hospitality and basketball culture are state identity markers. The simplicity of Indiana's tax administration is regularly cited by the Tax Foundation in its annual state competitiveness index. The 7% Indiana statutory portion plus local layers reach 7.00% on the Tax Foundation's 2026 combined-rate map. Enter the pre-tax amount; the page returns Indiana sales tax and total. At a — register the actual rate runs higher; in — closer to 7%. Indiana exempts most groceries (food sold for home consumption) and prescription drugs. Clothing is fully taxable.

Key Insight
Indiana's flat-statewide structure simplifies compliance and is one reason it consistently ranks well on tax-administration indexes. The 7% Indiana state rate gets layered with local jurisdictions to reach the 7.00% Tax Foundation combined figure — useful as a ballpark for Indiana shoppers and a sanity check for Indiana-bound sellers, but a multi-jurisdiction online retailer with Indiana nexus needs the destination-specific rate per ZIP (via Avalara, TaxJar, Stripe Tax). Indiana exempts most groceries (food sold for home consumption) and prescription drugs. Clothing is fully taxable.
Why the 'combined' rate matters
U.S. sales tax is layered: a state statutory rate plus local add-ons (county, city, special districts). For Indiana, the Tax Foundation publishes a single 'combined' figure by population-weighting all local rates — 7.00% as of January 2026.
This number is useful as a ballpark for consumer-side checkout estimation and statewide comparison, but it is NOT the rate you'd see at a specific store. Two stores in the same state, five miles apart, can have different combined rates because of district-level add-ons.
Wayfair (2018) and the destination-based rate
Before 2018, online sellers only collected sales tax in states where they had physical presence. South Dakota v. Wayfair changed that: a seller exceeding economic-nexus thresholds (typically $100k in sales or 200 transactions per state per year) must collect destination-based sales tax on shipments to that state.
Practical consequence for Indiana: if you buy online from an out-of-state seller above the nexus threshold, they should charge YOUR Indiana combined local rate, not theirs. If you're a seller, sales-tax automation (Avalara, TaxJar, Stripe Tax) handles the per-customer destination lookup.

Is sales tax on Amazon or Etsy orders to Indiana different?

If you're in Indiana, an out-of-state seller above the threshold applies your Indiana combined local rate at checkout, not their home-state rate.

What edge cases break this Indiana sales-tax estimate?

Also unreliable for Indiana category exemptions (this calculator uses the general retail rate, not reduced/exempt category rates) and for cross-border online sales where the destination's rate applies.
