Alabama taxes income at 2%, 4% and 5% – one of the few states that lets you deduct federal income tax paid – and several cities add an occupational tax on wages. Results are estimates for planning and ignore some credits, local rules and withholding differences.
How to use the Alabama Tax Calculator
- Gross annual income (wages)
- Pay frequency
- Filing status
- Children under 17
- Pre-tax deductions (401(k), HSA) per year
- Itemized deductions (0 = standard deduction)
- Local occupational tax
- Post-tax deductions per year
Results update as you type, and every field accepts the units shown in its menu.
How it works
Enter your gross salary, pay frequency, filing status, children under 17, pre-tax deductions, itemized deductions (leave 0 for the standard deduction) and any local option.
Tips
- Tax figures here are estimates for planning – your actual tax depends on credits, deductions and local rules.
- Check the tax year and filing status before you rely on a result.
- Use gross (before-tax) figures unless a field asks for take-home pay.
- When in doubt, confirm with the tax authority’s own calculator or a tax professional.
Common mistakes to avoid
- Confusing marginal and effective tax rates.
- Adding sales tax to a price that already includes it.
- Forgetting payroll taxes (Social Security and Medicare) on wages.

- Total income tax and FICA = [Federal income tax (after child tax credit)] + [FICA (Social Security + Medicare)] + [State income tax] + [Local income tax]
- Take-home pay per year = [Gross annual income (wages)] – [Pre-tax deductions (401(k), HSA) per year] – [Total income tax and FICA] – [Post-tax deductions per year]
- Take-home pay per paycheck = [Take-home pay per year]÷[Pay frequency]
- Effective tax rate = [Total income tax and FICA]÷[Gross annual income (wages)]×100
