Tennessee Income Tax Calculator & Refund Estimator

Compare federal income tax after credits with federal withholding year-to-date (W-2 box 2). If withholding is greater, the difference is a potential federal refund; if it is lower, you may owe the difference when filing. State tax is settled the same way on the state return against state withholding, and FICA (Social Security and Medicare) is withheld from pay and is not refunded or owed at filing.

This estimator includes federal income tax brackets, state income tax by state, employee FICA (Social Security and Medicare), and a simplified child tax credit model. It also accounts for common pre-tax adjustments like 401(k), HSA, and IRA contributions.

AGI is modeled as gross wages plus other income minus selected pre-tax contributions and half of entered student loan interest deduction. This is a planning approximation intended for quick tax forecasting, not filing preparation.

Refund estimates are sensitive to withholding, bonuses, side income, and credits. If your income pattern changes during the year, your final federal and state tax may differ from earlier estimates even with the same filing status.

A single filer earning $100,000 of W-2 wages in Tennessee (2026, standard deduction, no dependents) owes about $13,170.10 federal income tax, $0 Tennessee state tax, and $7,650 FICA — total tax around $20,820.10 (effective rate 20.82%).

No. Tennessee does not levy a state personal income tax on wages, so residents file only a federal return. State revenue comes from sales, property, and other taxes.

Federal tax returns are due April 15 (or the next business day if that falls on a weekend or holiday). Tennessee has no separate state income tax return for wages.

The federal standard deduction for 2026 is $16,100 for single filers and $32,200 for married filing jointly, applied before federal brackets. Tennessee has no state standard deduction because there is no state income tax on wages.

Your federal refund is federal withholding (W-2 box 2) minus federal income tax after credits — if withholding is higher you get a refund; otherwise you owe the difference. Tennessee has no state income tax on wages, so there is no state return to settle. FICA (Social Security and Medicare) is withheld from each paycheck and is not refunded or owed when you file. Common refund boosters: dependents (Child Tax Credit up to $2,000 each), 401(k) and HSA contributions reducing AGI, student-loan interest, and itemized deductions when they exceed the standard.
