The Formula Explained
We model Florida state income tax as:
LaTeX: $$T_{\text{state}} = r_{\text{state}} \times I_{\text{taxable}}, \quad \text{where } r_{\text{state}} = 0$$
Therefore, for any taxable income I: LaTeX: $$T_{\text{state}} = 0 \times I = 0$$
Glossary of Variables
- Income Type: Salary or Hourly, used to determine how income is entered and annualized.
- Pay Frequency: How often salary is paid (weekly, biweekly, semimonthly, monthly, annual).
- Gross Pay per Period: Total pay before any taxes or deductions for the selected period.
- Hourly Rate / Hours per Week / Weeks per Year: Inputs used to compute annual income for hourly workers.
- Florida State Income Tax Rate (r_state): Constant 0%.
- Per-Period State Income Tax: The portion of state tax for the selected period; always $0 in Florida.
- Annualized State Income Tax: Yearly total state tax; always $0 in Florida.
- Effective State Tax Rate: Florida state tax divided by income; always 0%.
How It Works: A Step-by-Step Example
Scenario: You earn a gross salary of $5,000 per month in Florida.
- Set Income Type to Salary; Pay Frequency to Monthly.
- Enter Gross Pay per Selected Period = $5,000.
- Apply the formula: LaTeX: $$T_{\text{state}} = r_{\text{state}} \times I_{\text{taxable}} = 0 \times 5{,}000 = 0$$
- Results:
- Per-Period State Income Tax = $0
- Annualized State Income Tax = $0
- Effective State Tax Rate = 0%
Tip: Federal income tax and FICA still apply and are separate from Florida state tax.
