Economic Nexus
Section titled “Economic Nexus”For informational purposes only · Not legal or tax advice · Consult a licensed tax professional · Rules as of 2026
Tennessee’s economic nexus threshold is $100,000 in gross sales into Tennessee in the current or prior 12-month period. Once exceeded, registration and collection are required.
Tennessee was one of the later states to formally adopt an economic nexus rule aligned with Wayfair. Marketplace-facilitated sales count toward the threshold. There is no transaction count alternative threshold.
Tax Rate and Product Taxability
Section titled “Tax Rate and Product Taxability”Tennessee’s state rate is 7%. Local jurisdictions add substantially:
- State: 7%
- County: typically 2.25%–2.75%
- Combined average statewide: approximately 9.547% — the highest average combined rate of any US state
- Combined in Nashville (Davidson): 9.25%
- Combined in Memphis (Shelby): 9.75%
- Combined in Knoxville (Knox): 9.25%
Tennessee uses destination-based sourcing for remote sellers.
Product Categories
Section titled “Product Categories”Taxable: Tangible personal property, digital goods (including SaaS), most retail goods.
Exempt: Prescription drugs, most groceries (food for home consumption is subject to a reduced 4% state rate — see below), qualifying agricultural inputs.
Grocery reduced rate: Tennessee applies a reduced 4% state rate on food and food ingredients for home consumption (vs. the standard 7%). Local rates still apply at full rate. This means groceries in Tennessee run approximately 6.25%–7% depending on county, not the full 9%+ rate.
Digital Goods and SaaS
Section titled “Digital Goods and SaaS”Tennessee taxes SaaS and digital goods under its sales tax framework:
- SaaS — taxable; Tennessee’s Department of Revenue treats remotely accessed software as a taxable “specified digital product” or taxable service
- Downloaded software — taxable
- Digital content (music, ebooks, streaming video and audio) — taxable
- Online subscriptions for digital products — taxable
Tennessee expanded its digital goods taxability framework and has applied sales tax to a wide range of digital transactions. SaaS sellers crossing $100,000 in Tennessee revenue have a clear obligation.
