Tennessee S-Corp Tax Calculator

Self-employment tax is federal — 15.3% (12.4% Social Security up to the $184,500 wage base + 2.9% Medicare) on 92.35% of your net self-employment income, the same in Tennessee as everywhere. Tennessee then taxes that same income at its state income-tax rate (none — no state income tax). The calculator above shows your SE tax at any income.

In Tennessee, at this calculator's default assumptions, it starts paying off at $292,277 of net profit. That assumes a salary of 60% of net profit (capped at the $184,500 Social Security wage base), $2,500 a year for payroll and the extra business return, a single filer with no other income taking the $16,100 standard deduction, a business that is not a specified service business (not consulting, law, health, financial services and the like) and an LLC you already have, so its annual fee is paid either way. It counts federal payroll tax, federal income tax (including the QBI deduction the salary changes) and what TN charges for the election. Your own state income tax is not in it. A lower defensible salary moves the answer, and so do your own payroll and return quotes.

Tennessee's 6.5% excise tax reaches an S-corp's net income. Your LLC already files franchise and excise tax but can deduct the income that is subject to self-employment tax, so the excise on the S-corp's income is new; the net-worth franchise tax is owed either way and is not counted.

Tennessee does not currently offer a pass-through entity tax (PTET) election, so the federal SALT cap ($40,400 for 2026, phasing down toward $10,000 above ~$505,000 of MAGI) applies to state taxes paid personally.

The IRS requires S-corp owner-employees to pay themselves a reasonable salary (subject to FICA) before taking distributions. This calculator assumes a salary of 60% of net profit (capped at the $184,500 Social Security wage base), with the rest taken as distributions, as an illustration — your actual reasonable compensation depends on your role and industry and should be set with a CPA.
