Tennessee Economic Nexus Threshold: The $500K-to-$100K Revenue-Only Rule With No Transaction Count

How Tennessee Got From $500K to $100K

Tennessee enacted its economic nexus rule effective October 1, 2019, setting the threshold at $500,000 in gross revenue with no transaction-count requirement. At that level, Tennessee joined California and Texas as the three states with $500K floors — a meaningful contrast to the $100K standard adopted by the vast majority of states following South Dakota v. Wayfair.

The $500K threshold was always intended as a transitional measure. Tennessee's legislature built in a planned reduction: on October 1, 2020, the threshold dropped to $100,000, bringing Tennessee in line with the national majority. The original $500K figure gave remote sellers a one-year runway to prepare systems, register if needed, and begin collecting.

Why does the $500K history matter today? Three reasons. First, sellers who were active in Tennessee between October 2019 and September 2020 may have retroactive exposure if they exceeded $500K during that window but never registered. Second, the Franchise & Excise Tax — Tennessee's business tax on net worth and income — still uses a $500,000 threshold for economic nexus, creating confusion when sellers see “$500K” referenced in Tennessee guidance without realizing it applies to F&E, not sales tax. Third, Tennessee remains a revenue-only state: no transaction count, just dollars.

What “Gross Revenue” Means in Tennessee

Tennessee measures the threshold against gross revenue from sales of tangible personal property, specified digital products, and certain services delivered into the state. This is broader than “taxable sales” and includes:

• Exempt sales — sales to exempt organizations (nonprofits, government entities) count toward the threshold even though no tax is collected on those transactions.
• Reduced-rate items — food and food ingredients are taxed at a reduced state rate in Tennessee (4% instead of the standard 7%), but the full sale amount counts toward the threshold.
• Wholesale sales — sales made for resale where the buyer provides a valid resale certificate still count toward your gross revenue figure for nexus purposes.
• Digital products — specified digital products (ebooks, music, software) are taxable in Tennessee. Sales of these items count toward the threshold.

What is excluded: returns and allowances reduce your gross revenue figure. Marketplace-facilitated sales — transactions where a marketplace facilitator like Amazon collected and remitted the tax — are also excluded from your personal threshold calculation.

Marketplace Facilitator Exclusion: What Counts and What Doesn't

Tennessee's marketplace facilitator law, effective October 1, 2020, requires marketplace facilitators to collect and remit sales tax on sales they facilitate into the state. For individual sellers, this creates a critical exclusion: sales made through a registered marketplace facilitator do not count toward your $100,000 economic nexus threshold.

This is the same marketplace exclusion rule that applies in most states. If you sell $80,000 through your own Shopify store and $120,000 through Amazon into Tennessee, only the $80,000 counts toward your threshold. Amazon is handling tax on the $120,000 as a facilitator. You are below $100,000 in countable revenue and have no economic nexus.

Be cautious with platforms that may not qualify as marketplace facilitators in Tennessee. Shopify is not a marketplace facilitator — it is a commerce platform and payment processor. All sales through your Shopify storefront are direct sales that count toward the threshold. The same applies to WooCommerce, BigCommerce, and similar platforms where you operate your own store.

Worked Example: Month-by-Month Rolling 12-Month Threshold Tracking

This is where most guides stop at the headline number and leave sellers to figure out the math. Here is a concrete example showing how a real seller determines whether they have crossed Tennessee's threshold mid-year.

The critical lesson: a seller with $280,000+ in total Tennessee revenue (direct plus Amazon) only has $103,700 in countable revenue. Without understanding the marketplace facilitator exclusion, this seller might have registered months earlier — or panicked at the total revenue figure. With proper tracking, they identified the exact month they crossed and can time their registration accordingly.

Registration via TNTAP: Step-by-Step

Once you determine that your rolling 12-month direct sales into Tennessee exceed $100,000, you must register to collect and remit Tennessee sales tax. Registration is done through the Tennessee Taxpayer Access Point (TNTAP), the state's online tax portal.

1. Go to tntap.tn.gov and create an account if you do not already have one. You will need your federal EIN and basic business information.
2. Select “Register a New Tax Account” and choose “Sales and Use Tax” as the tax type. Remote sellers select the out-of-state seller designation.
3. Provide your business details: legal name, DBA, physical address, mailing address, NAICS code, date business began in Tennessee (the date you crossed the threshold), and ownership information.
4. Submit and wait for confirmation. TNTAP typically processes registrations within a few business days. You will receive a Tennessee sales tax account number and your filing frequency (monthly or quarterly, based on expected volume).
5. Begin collecting Tennessee sales tax on all taxable direct-channel sales shipped to Tennessee customers. The standard state rate is 7%, with local rates adding 1.5% to 2.75% depending on the jurisdiction.

Tennessee does not charge a registration fee for out-of-state sellers. Once registered, you must file returns on time even in periods with zero tax due. Late registration after crossing the threshold can result in penalties and interest on uncollected tax.

Tennessee vs. Other Revenue-Only States

Tennessee is not alone in dropping the transaction-count prong. Several states use revenue-only tests, but the threshold amounts vary significantly:

The practical difference for multi-state sellers: in Tennessee, a high-volume, low-dollar-value seller (think $8 phone accessories with 15,000 orders) can avoid nexus entirely as long as total direct revenue stays under $100,000. In states with a 200-transaction prong, that same seller would have triggered nexus after their 200th order — potentially at only $1,600 in revenue. Tennessee's revenue-only approach is structurally more favorable for high-transaction, low-AOV sellers.

The Franchise & Excise Tax Trap: Don't Confuse the Two $500K Figures

A common source of confusion: Tennessee's Franchise & Excise (F&E) Tax has its own economic nexus threshold of $500,000 in Tennessee receipts, and this threshold is still active. When sellers search for “Tennessee $500,000 threshold,” they may find references to the F&E tax and mistakenly believe the sales tax threshold is still $500K.

The two are entirely separate obligations:

• Sales and Use Tax: $100,000 gross revenue threshold. Applies to the sale of tangible personal property, digital products, and certain services. You collect from customers.
• Franchise & Excise Tax: $500,000 threshold in Tennessee receipts (or $500,000 in property, or at least 25% of total receipts/property/payroll). A business-level tax on net worth (franchise) and net income (excise). You pay this directly as a business expense — it is not collected from customers.

A seller with $350,000 in direct Tennessee sales has economic nexus for sales tax (well above $100K) but does not have F&E nexus (below $500K). A seller with $600,000 in direct Tennessee sales has both. The registration processes are separate, and the obligations are independent of each other.

SaaS and Digital Products in Tennessee

Tennessee is one of the states that tax SaaS and digital products. Software delivered electronically, streaming services, and digital downloads are all subject to Tennessee sales tax. For SaaS companies, this means monthly subscription charges to Tennessee customers count toward the economic nexus threshold as gross revenue.

Because Tennessee uses a revenue-only threshold with no transaction count, a SaaS company with 500 Tennessee subscribers paying $15/month ($90,000 annual revenue) would be below the $100,000 threshold. Add a few enterprise contracts and the math changes quickly. SaaS sellers should track Tennessee subscription revenue monthly — recurring revenue accumulates predictably and the crossing point can be calculated in advance.

Retroactive Exposure: The October 2019 – September 2020 Window

Sellers who exceeded $500,000 in Tennessee gross revenue between October 1, 2019, and September 30, 2020, had economic nexus under the original threshold but may never have registered. If Tennessee identifies these sellers through audit or data sharing, the state can assess back taxes, penalties, and interest for the period when collection was required but not performed.

Tennessee participates in the Streamlined Sales Tax (SST) program, which offers a voluntary disclosure mechanism for sellers who want to come into compliance. If you believe you had exposure during the initial $500K period and never registered, a voluntary disclosure agreement (VDA) can cap your look-back period and reduce or eliminate penalties. This is significantly more favorable than waiting for the state to find you.

Filing Deadlines and Rates

Once registered, Tennessee assigns a filing frequency based on your expected tax liability:

• Monthly filers: Returns due by the 20th of the following month. Required for sellers with more than $400 in average monthly tax liability.
• Quarterly filers: Returns due by the 20th of the month following the quarter end (April 20, July 20, October 20, January 20). For sellers with lower volume.

Tennessee's state sales tax rate is 7%. Local jurisdictions add between 1.5% and 2.75%, making the combined rate typically 8.5% to 9.75% depending on the delivery address. Tennessee requires destination-based sourcing for remote sellers — you apply the rate for the customer's shipping address, not your business location.
