You ship a product to a customer in Nashville, or you land a service contract in Memphis, and suddenly your Florida operation has Tennessee tax exposure. If you’re a Florida business selling into Tennessee—whether goods, digital products, or certain services—you’re responsible for understanding and collecting Tennessee sales tax from your customers, then remitting it to the state. This creates a second compliance obligation on top of your Florida sales tax duties, with its own rules, rates, and deadlines. Many Florida owners don’t realize they’ve triggered a filing requirement until a notice arrives. The good news: Tennessee’s system is straightforward once you know the structure, and you can set up a reliable filing routine that keeps both states happy without consuming your day.
Whether you’re the business owner juggling the back office yourself, or the CPA supporting one, see how the platform keeps the numbers organized — your first period is free for a limited time, no credit card required.
Does this apply to your business in Florida?
If you have economic nexus with Tennessee—meaning you ship tangible personal property to customers there, or generate income from services performed in Tennessee—you must register for a Tennessee sales tax permit and collect tax on sales. In Tennessee, tangible personal property (physical goods) is subject to sales tax, and certain services are taxable depending on the nature of the work. The Tennessee Department of Revenue taxes most retail sales. The simplest rule: if you’re making sales to Tennessee customers and have no nexus exemption, file.
How the rate works
Tennessee’s state sales tax rate is 9.55%. This rate is fixed and applies statewide, unlike Florida’s county-variable model. Tennessee does not allow county-level local surtaxes the way Florida does; instead, cities and certain transit districts within counties may apply local options taxes in specific zones. For most businesses selling across Tennessee, you’ll use the 9.55% state rate when calculating tax due on taxable sales. Because Tennessee’s rate is higher than Florida’s typical combined rate (Florida’s state rate is 6% plus county surtax), your customer cost jumps when you’re selling Tennessee-bound goods. The Tennessee Department of Revenue website includes a rate calculator and localized rate tables if you’re selling into specific cities or districts with local options taxes. Always confirm the current rate and any local variations before filing.
How to file step by step
Tennessee sales tax returns are filed monthly using Form ST-103M (sales and use tax return). Here’s the general flow:
Step 1: Register online. Go to Tennessee Department of Revenue and select online registration. You’ll provide your federal employer identification number (EIN), business name, address, nature of your business, and expected sales. You don’t need to have made any Tennessee sales yet—economic nexus alone triggers the requirement. Tennessee will issue you a sales tax permit (also called a seller’s permit) within days.
Step 2: Collect tax on taxable sales. Apply the 9.55% state rate (or the applicable local rate if you’re selling in a city with a local option tax) to all taxable sales made to Tennessee customers. For products, this is straightforward. For services, check whether your service type is taxable under Tennessee law—services are taxable unless specifically exempted, so verify your category with the state if you’re unsure.
Step 3: Track and calculate monthly. At the end of each month, add up your taxable sales and multiply by the rate(s) that applied. If you operate a website with automatic checkout, configure your cart to apply Tennessee tax automatically. If you invoice manually, calculate and add the tax to each invoice. Keep records of all sales by state and tax rate.
Step 4: File by the 20th of the following month. Tennessee requires returns to be filed by the 20th of the month following the sales month. You can file online through the Tennessee Department of Revenue’s portal, or use an automated filing service if you’ve linked your accounting platform to Tennessee’s system. Enter your total taxable sales, tax calculated, and any credits or adjustments. Submit the return and the tax payment together.
Step 5: Remit payment. Tennessee allows online payment through the Department of Revenue’s portal. Pay the full amount due by the 20th deadline. If you’re also filing Form ST-103, the annual reconciliation form, do so by March 20 each year to true up any variances between monthly filings.
Common mistakes
Forgetting to register is the most expensive error. A business that sells into Tennessee for three months without registering will owe back tax plus interest and penalty when caught. The penalty for failure to register can add up quickly. Register as soon as you have economic nexus, even if you’ve already made a few sales. It takes minutes online.
Mixing up Tennessee’s rate with Florida’s is a second common slip. Tennessee’s state rate is 9.55%—not 6% plus a surtax. It’s a fixed statewide rate. If you’re used to calculating Florida tax and you accidentally apply 7% to Tennessee sales (forgetting the local option), you’ll underpay and owe a catch-up. Build separate tax calculations into your billing process for each state, or use a platform that applies rules by jurisdiction automatically.
Not verifying whether a service is taxable causes trouble for service providers. Tennessee taxes many services that Florida doesn’t—for example, certain consulting, installation, and labor services are taxable in Tennessee. If you assume a service is not taxable in Tennessee because it isn’t in Florida, you’ll miss tax collection and owe it yourself later. Confirm your service category with the Tennessee Department of Revenue before you start invoicing.
Failing to keep adequate records invites audits. Tennessee auditors often review sales and use tax returns to verify that businesses reported all taxable sales and applied the correct rates. If your accounting system doesn’t separate Tennessee sales from other state sales, or if invoices don’t show tax applied, you won’t be able to defend your filings. Use accounting records that clearly show which sales were to Tennessee, the amounts, and tax applied to each.
Frequently Asked Questions
Do I need a separate permit for Tennessee, or can I use my EIN?
You need a separate Tennessee sales tax permit. Your federal EIN identifies your business to the IRS, but each state requires its own sales tax registration and permit number. Register with the Tennessee Department of Revenue online—it’s free and takes minutes. You’ll use the permit number on all Tennessee filings.
What if I’m a Florida service business, not a product seller?
Services are taxable in Tennessee only if they fall under specific categories listed by the state. Common taxable services include labor, installation, repairs, and certain professional services. Services like accounting, legal advice, and real estate brokerage are not taxable. Identify your service in Tennessee’s tax code. If you’re unsure, ask the Tennessee Department of Revenue in writing; they’ll provide a ruling letter you can reference later. Outsourcing Processing can help organize your service income by state and service type so you’re clear on what’s taxable.
What’s the deadline if I miss it?
Returns are due by the 20th of the following month. If you miss that date, you’ll owe a late-filing penalty on top of the tax. Tennessee allows some grace periods for first-time or good-faith filers, but don’t rely on it. Set a calendar reminder for the 15th of each month so you have a buffer. Paying early is always safer than scrambling on the last day.
Can I offset Tennessee tax with credits for tax paid in Florida?
No. Florida and Tennessee don’t have a reciprocal credit agreement. If you collected tax in both states on the same sale, you owe both. The key is to avoid double-taxing the same transaction. If the customer is in Tennessee and you ship to Tennessee, apply Tennessee tax, not Florida. If the customer is in Florida, apply Florida tax. Proper nexus tracking prevents double-tax situations.
Who should file the return if I have a CPA?
You can file yourself through the Tennessee Department of Revenue portal, or your CPA can file on your behalf. Many CPAs charge a per-return fee for multi-state returns, which adds up fast if you have economic nexus in multiple states. Some Florida businesses organize their transaction data by state and have their CPA review it rather than prepare it, which often costs less. The Tennessee Department of Revenue’s online filing system is simple enough that a business owner or bookkeeper can do it, freeing your CPA for higher-level strategy.
What records do I need to keep?
Keep all sales invoices, receipts, shipping documents, and bank statements showing payments from Tennessee customers. If you use accounting software, export reports showing sales by state and tax applied. Keep these records for at least three years. If Tennessee audits you, they’ll ask for proof that you reported all taxable sales and applied the correct rate. Clear records speed up the process and reduce penalty risk.

Keep both states running smoothly
Expanding your Florida business into Tennessee means handling two sales tax systems, two rates, and two filing deadlines. The work is manageable once you organize your transactions by state from the start. Register promptly, track sales separately, verify which services are taxable in each state, and file by the 20th of each month. Your compliance routine protects you from penalties and keeps auditors off your back.
