Tennessee S-Corp Pitfalls: The 6.5% Excise Tax, Franchise Tax, and the Single-Member LLC Trap

Take a marketing consultant in Nashville with a single-member LLC that clears $150,000 a year. She has read that an S-Corp election saves self-employment tax, but a friend warned her that "corporations pay Tennessee franchise and excise tax," so she has held off. The owner is theoretical, not an EntityIQ client, but the hesitation is common and it rests on a mistake. Her LLC has owed Tennessee franchise and excise tax the whole time. The election she is afraid of would actually cut her state bill.

Tennessee taxes the entity, not the person

Tennessee has no personal income tax on wages or business profit, and the Hall tax on interest and dividends is gone too. What Tennessee has instead is a pair of entity-level taxes, the franchise and excise taxes, imposed on every entity that enjoys limited liability protection and does business in the state. That covers LLCs, S corporations, C corporations, and limited partnerships. It does not cover a true sole proprietorship or a general partnership, because those carry no liability shield.

The rates for 2026: The Tennessee excise tax is 6.5% of net earnings from business done in the state, after a standard deduction of up to $50,000 that applies for tax years ending on or after December 31, 2024. The franchise tax that rides along with it is 0.25% of net worth, with a $100 minimum, and since 2024 it is measured on net worth alone. The $50,000 standard deduction came from the Tennessee Works Tax Act of 2023, explained in Department of Revenue Notice 23-04, and it cannot create a loss. Public Chapter 950 of 2024 repealed the old property measure of the franchise tax, so a service business with modest equity usually just pays the $100 minimum. Both taxes go on Form FAE 170, due April 15 for calendar-year filers, with quarterly estimates once your combined liability reaches $5,000.

The single-member LLC trap

Here is the part that surprises people. Federally, a single-member LLC is a disregarded entity, so its owner reports the profit on Schedule C and the LLC files nothing of its own. Tennessee does not follow that treatment. A single-member LLC owned by an individual must file its own Tennessee franchise and excise tax return even though it is disregarded for federal purposes. Tennessee only disregards an LLC when its single member is a corporation, so an individual-owned LLC pays the 6.5% excise tax and the 0.25% franchise tax on Form FAE 170 every year. The Department of Revenue spells this out in its guidance on filing requirements for disregarded entities.

So the Nashville consultant already owes excise tax on her Schedule C profit. On $150,000 of net earnings, the first $50,000 comes off as the standard deduction and the remaining $100,000 is taxed at 6.5%, which is $6,500, plus the $100 minimum franchise tax. If she has been skipping that filing, the fix is registration through TNTAP and catching up. The exemptions people cite, FONCE and the obligated member entity election, are built for passive investment entities and members who give up their liability shield, and an operating consulting business fits neither.

The salary twist: the S-Corp election cuts the excise tax

Now the good news. If your business is already an LLC, the S-Corp election does not trigger Tennessee franchise and excise tax, because the LLC has owed both taxes all along. Tennessee taxes registered limited liability entities regardless of how they are classified federally, so the election changes the federal payroll tax math without adding a state filing you did not already have. Better, the election does something an SMLLC cannot: an S corporation deducts the W-2 salary it pays its owner, and Tennessee's excise base starts from that federal computation.

Wages the S corporation pays you are deductible in computing its net earnings, while a single-member LLC gets no deduction for the owner's draw. On $150,000 of profit with a $70,000 salary, the excise bill falls from $6,500 to about $1,602, a state-level saving of nearly $4,900 that stacks on top of the federal payroll tax saving. On the federal side, a sole proprietor pays self-employment tax under IRC §1401 of about $21,194 on $150,000 of profit, while an S-Corp owner pays FICA on the $70,000 salary only, about $10,710 counting both halves. Figures below are rounded, and the franchise tax stays at the $100 minimum in both columns.

The usual caveats still apply. The $70,000 salary has to be reasonable compensation, the payroll service costs a few hundred dollars a year, and the shift slightly changes the qualified business income deduction under IRC §199A. But where a Californian weighs the federal saving against a new 1.5% entity tax, a Tennessean gets a state-level discount for making the same move.

No PTET, and why nobody misses it

Tennessee has no pass-through entity tax election because it has no personal income tax to work around, the Hall tax on interest and dividends having been fully repealed as of January 1, 2021. The franchise and excise taxes are already imposed on the entity itself, so they are deductible on the federal 1120-S as ordinary business taxes without touching the SALT cap. That is the federal benefit a PTET delivers, with no election, no deadline, and none of the resident-credit headaches I covered in the Georgia and New Jersey guides. In the 24% federal bracket, the consultant's $1,702 of Tennessee tax really costs about $1,294 after the deduction.

The one true pitfall: electing from a naked sole proprietorship

Everything above assumes you already run an LLC. If you operate with no entity at all, just a Schedule C under your own name, you owe Tennessee nothing, because the franchise and excise taxes attach to the liability shield. Forming an LLC or corporation to make the S-Corp election is what pulls you into the tax, and the 6.5% excise on post-salary profit then eats into the federal payroll saving. The $50,000 standard deduction softens the hit, and liability protection has value on its own, but run the number before you file the paperwork. Below roughly $60,000 of profit, where the federal saving is thin to begin with, the Tennessee entity tax can tip the answer to no.

A practical read for Tennessee owners

If your business is already a Tennessee LLC with solid profit, the S-Corp election is unusually attractive here. You were paying franchise and excise tax anyway, the election shrinks the excise base by your salary, and there is no state income tax or PTET machinery to manage. Confirm the LLC is actually filing Form FAE 170, pick a defensible salary, and file Form 2553 on time. If you are a sole proprietor with no entity, price in the excise tax before you leap.

Start with the EntityIQ S-Corp tax calculator to see the federal savings at your profit and salary, check how the $184,500 Social Security wage base shapes the answer at higher incomes, and read the reasonable compensation guide before you set the salary that drives both the federal and the Tennessee math.
