The Formula Explained
TN State Tax Rate: r = 0
LaTeX:
1) Total Income Considered: I_c = W + I + D
2) State Tax: T_{TN} = I_c × r = (W + I + D) × 0 = 0
3) Effective Rate: ER = { T_{TN} \over \max(I_c, 1) } × 100%
W = wages; I = interest; D = dividends. For 2021 onward, r = 0 per Tennessee law.
Glossary of Variables
- Year: Supported tax year (2021–2025), all with a 0% Tennessee state income tax rate.
- Annual wage income (W): Gross wages, salaries, and tips subject to federal tax. Tennessee does not tax wages.
- Interest & dividends (I + D): Investment income. The Hall tax that once applied was repealed for 2021 onward.
- TN state tax rate (r): 0% for 2021–2025.
- TN state income tax (T_TN): State tax due to Tennessee income tax. Result is $0.
- Effective state tax rate (ER): T_TN divided by total income considered (displayed as a percent).
How It Works: A Step-by-Step Example
Scenario: A Tennessee resident in 2025 earns $65,000 in wages and $0 in interest/dividends.
- Choose Year = 2025.
- Enter W = $65,000; I + D = $0. Then I_c = W + I + D = $65,000.
- Apply Tennessee rate r = 0% (per state law, 2021–2025).
- Compute state tax: T_TN = I_c × r = $65,000 × 0 = $0.
- Effective rate: ER = T_TN / I_c × 100% = 0 / 65,000 × 100% = 0.00%.
Answer: Tennessee state income tax = $0.00; Effective Tennessee state tax rate = 0.00%.
