It depends on where you cross each state's economic nexus threshold (or have physical presence there). Indiana's published threshold is $100,000, and Kentucky's is $100,000 or 200 transactions. You generally register in a state only once you cross its threshold, so you may have an obligation in one, both, or neither.

Indiana — nexus note

Indiana sales tax nexus and economic nexus threshold: more than $100,000 in gross revenue from sales into Indiana in the current or preceding calendar year. Effective January 1, 2024, Indiana removed its prior 200-transaction test; the state now uses a sales-only threshold. Indiana DOR Sales Tax Information Bulletin #89 says the threshold includes tangible personal property delivered into Indiana, products transferred electronically into Indiana, and services delivered in Indiana, including exempt sales and wholesale transactions. Services are sourced to Indiana when the buyer first uses them in Indiana, but a seller that provides only nontaxable services generally is not required to register solely because it crosses the threshold. Marketplace facilitators count both their own Indiana sales and facilitated marketplace sales toward the $100,000 threshold; marketplace sellers generally exclude sales made through registered marketplaces from their own Indiana threshold test unless the marketplace facilitator has not met the threshold. Indiana's statewide sales tax rate is 7%, with no local sales-tax add-on, and remote sellers with less than $1,000 in annual Indiana sales-tax collections generally file annually. Indiana DOR source data last retrieved 2026-06-01.

Kentucky — nexus note

Kentucky sales tax nexus and economic nexus threshold: through July 31, 2026, a remote retailer must register and collect Kentucky sales tax once it has $100,000 or more in gross receipts from sales into Kentucky OR 200 or more separate sales into Kentucky in the previous or current calendar year — meeting either test triggers the requirement (Kentucky Department of Revenue Wayfair guidance, HB 487; collections required beginning October 1, 2018). Effective August 1, 2026, House Bill 757 (2026 Regular Session, enacted over the Governor's veto) removes the 200-transaction test for both remote retailers and marketplace providers, leaving a $100,000 sales-only threshold that counts tangible personal property, digital property, and services delivered, transferred electronically, or provided to a Kentucky purchaser; sellers registered solely because of transaction volume should review whether they can deregister under Kentucky's trailing-nexus rules. Kentucky's marketplace facilitator law (HB 354) has been effective since July 1, 2019 — Amazon, Etsy, eBay, and Walmart collect and remit Kentucky sales tax on facilitated sales, registering once for all third-party sellers per KRS 139.450 (procedure clarified by HB 249, effective July 1, 2021). Kentucky levies a flat 6% statewide sales tax with no local sales taxes, so the rate is identical at every Kentucky delivery address. HB 757 also extends Kentucky sales and use tax to data brokering services beginning August 1, 2026. Direct-to-consumer sales outside any marketplace remain the seller's own collection responsibility once nexus is met.
