You are selling into Tennessee and you need to collect sales tax legally. You register for free through the Tennessee Department of Revenue (DOR) using the Tennessee Taxpayer Access Point (TNTAP), the DOR’s online portal. The DOR then issues your sales and use tax certificate of registration.
The table below covers the numbers most sellers ask about first: cost, threshold, rate, and timing.

What Is a Tennessee Sales Tax Permit?
A Tennessee sales tax permit is the sales and use tax certificate of registration issued by the DOR, and it authorizes you to collect and remit sales tax on taxable sales. Searchers call it a sales tax permit or seller’s permit, and the terms are interchangeable in practice. The DOR’s formal instrument is the certificate of registration, which you must display at your business location.
Tennessee leans hard on sales tax because it has no state income tax on wages. The Hall income tax on interest and dividend income was fully repealed for tax years beginning January 1, 2021, per the Tennessee DOR. That is a large reason the 7% state base rate is one of the highest in the country.
Do You Need a Sales Tax Permit in Tennessee?
Yes, if you have physical presence in Tennessee and make taxable sales, or if you are a remote seller with more than $100,000 in Tennessee sales in the prior 12 months. Tennessee also requires in-state businesses to register once projected gross sales of tangible personal property exceed $4,800 per year, or taxable services exceed $1,200 per year, per the DOR’s Application for Registration (Form RV-F1300501).
| Nexus trigger | Creates a permit obligation? | Source |
|---|---|---|
| Physical location or office in Tennessee | Yes | Tennessee DOR |
| Inventory stored in-state, including Amazon FBA stock | Yes | Tennessee DOR |
| Employees or sales reps in Tennessee | Yes | Tennessee DOR |
| Company-owned property in-state | Yes | Tennessee DOR |
| Trade-show or temporary in-state presence | Yes | Tennessee DOR |
| $100,000+ in Tennessee sales (prior 12 months) | Yes, economic nexus | Tennessee DOR |
Fulfillment by Amazon (FBA) inventory is the trigger sellers miss most. The moment your stock sits in a Tennessee warehouse, you have physical nexus regardless of the stock’s value.
What Are Tennessee’s Sales Tax Nexus Rules in 2026?
Tennessee’s economic nexus threshold is $100,000 in sales to Tennessee customers in the previous 12-month period, with no separate transaction-count trigger, per the Tennessee DOR. That is the genuine difference from states that use a “$100,000 or 200 transactions” rule. In Tennessee, sales dollars are the only test.
The threshold was originally $500,000. Public Chapter 759 (2020) lowered it to $100,000 effective October 1, 2020, per the Tennessee DOR. The threshold counts your sales into Tennessee, including exempt retail sales but excluding sales for resale. For how the $100,000 figure compares state by state, see Commenda’s US economic nexus guide and the Tennessee sales tax guide.
What Is the Tennessee Sales Tax Rate?
Tennessee’s state sales tax rate is 7%, one of the highest base rates in the US, plus local option rates of up to 2.75%. Combined rates commonly land between 9.25% and 9.75%. Groceries carry a reduced state rate of 4% plus local tax.
| Rate | Amount | Source |
|---|---|---|
| State sales tax rate | 7% | Tennessee DOR |
| Maximum local option rate | 2.75% (in 0.25% increments) | Tennessee DOR |
| Combined general rate (max) | 9.75% | Tennessee DOR |
| Reduced food rate | 4% state (plus local) | Tennessee DOR |
| Average combined rate | 9.56%, 2nd-highest nationally | Tax Foundation |
The 4% food rate has applied since July 1, 2017, when the IMPROVE Act cut it from 5%, per the Tennessee DOR. Repeal bills in the 2026 legislative cycle stalled, so the 4% grocery rate still stands.
How Do You Find the Right Local Rate for a Sale?
The correct rate depends on the local jurisdiction and Tennessee’s sourcing rules, and the DOR publishes a local sales tax rate table sellers use to match the right county or city rate. In-state sales are generally sourced to the seller’s location, and sales shipped from out of state are sourced to the Tennessee delivery address. Every Tennessee jurisdiction levies a local rate.

What Information Do You Need to Register?
You need your legal name, entity type, EIN, addresses, NAICS code, responsible party details, nexus start date, and estimated sales. Have the full checklist ready before you open TNTAP.
| Field | Detail |
|---|---|
| Legal business name and DBA | Legal name, plus any “doing business as” (DBA) trade name |
| Entity type | Sole proprietor, LLC, corporation, or partnership |
| EIN | Federal Employer Identification Number; sole props without employees may use an SSN |
| Addresses | Physical and mailing address |
| NAICS code | e.g. 445110 retail, 454110 nonstore/ecommerce |
| Responsible party | Name, title, and SSN |
| Start date | Business or nexus start date |
| Estimated sales | Estimated monthly taxable sales, which drives filing frequency |
| Bank details | Account information for remittance |
How Do You Get a Tennessee Tax ID Number?
“Tennessee tax ID number” means one of three distinct numbers, and which one you need depends on the task. Confusing them is a common registration error, so match the number to the job before you start.
- Federal EIN. A nine-digit number issued free by the IRS. The online tool issues it immediately.
- Tennessee sales tax account number. Issued by the DOR when your TNTAP registration completes.
- Franchise and excise tax account. A separate DOR registration for entities such as LLCs and corporations.
The EIN is always free from the IRS. Avoid third-party sites that charge a fee to obtain one for you.
How Much Does a Tennessee Sales Tax Permit Cost?
Registration is free. Tennessee charges no application fee and no renewal fee to register a sales and use tax account, per the DOR’s SUT-10 guidance. Some states do charge a registration or per-location fee, but Tennessee does not, which keeps your startup compliance cost at zero.
How Long Does It Take to Get a Tennessee Sales Tax Permit?
Online TNTAP registrations are often processed within a few days, with roughly 10 business days as the outer bound. The account or registration number can arrive before the physical certificate, and you can legally begin collecting once your application is submitted. Submitting a clean, error-free application is the fastest path, so review every field before you send it.
Do You Need Your Own Permit If You Only Sell Through Amazon or Other Marketplaces?
Probably not, if 100% of your Tennessee sales run through a marketplace that collects. Tennessee requires marketplace facilitators to collect and remit tax on facilitated sales once they exceed $100,000 in Tennessee sales, effective October 1, 2020, per the Tennessee DOR. A seller whose Tennessee sales are entirely facilitated generally does not need its own registration.
Any direct sales change that conclusion. Sales through your own website, wholesale orders, or in-person sales trigger the normal nexus analysis and can require your own permit.
What Are the Rules for Out-of-State and Remote Sellers?
Remote sellers register once they cross $100,000 in Tennessee sales in the prior 12 months, or immediately if they establish physical presence. Physical presence includes FBA inventory in a Tennessee warehouse or a Nashville trade-show booth, both of which create nexus below the $100,000 line.
Once registered, collect tax at the rate for the delivery location under Tennessee’s sourcing rules, and keep detailed sales records. Remote sellers are audited often, so retain invoices and shipping documentation showing where each order went.
How Do You Collect and Remit Tennessee Sales Tax After Registering?
The DOR assigns you a monthly, quarterly, or annual filing frequency based on your estimated tax liability, and you file and pay through TNTAP by the 20th. Tennessee does not publish fixed public liability cutoffs for each frequency, so the DOR sets your cadence at registration from your estimated sales.
| Filing frequency | Due date | Source |
|---|---|---|
| Monthly | 20th of the following month | Tennessee DOR |
| Quarterly | January 20, April 20, July 20, October 20 | Tennessee DOR |
| Annual | January 20 | Tennessee DOR |
File a return every period even when you have no sales. A zero return keeps your account in good standing, and late filing brings penalties and interest. Keep your TNTAP contact and bank details current so payments clear on time.
What Are Common Mistakes When Registering for a Tennessee Sales Tax Permit?
The most common errors are avoidable with a careful application and a clear read of nexus. Each one either delays approval or creates back-tax exposure.
- Registering under a DBA instead of the legal business name.
- Choosing the wrong NAICS code for your activity.
- Misreading nexus and registering too late, or not at all.
- Leaving required fields, such as the EIN, blank.
- Ignoring FBA inventory that has already landed in a Tennessee warehouse.
- Forgetting to file zero returns after approval.
