How to Use This Calculator
Tab "Take-Home Pay"
Enter your gross annual salary, pay frequency, and filing status. The calculator first computes your 2026 federal income tax, then uses that amount as a deduction on your Alabama state return — a unique feature of Alabama tax law. It applies Alabama state income tax brackets (2%–5%), FICA taxes (Social Security 6.2% up to $184,500, Medicare 1.45%, and the 0.9% Additional Medicare Tax above $200K). Expand "More options" to add pre-tax 401(k) contributions and health insurance premiums. The result shows your net take-home per paycheck plus a full annual summary, including how much the federal tax deduction saves you.
Tab "Tax Breakdown"
This tab shows a visual pie chart of where every dollar of your salary goes: federal tax, AL state tax, Social Security, Medicare, and take-home pay. It calculates how many cents of each dollar you actually keep and your combined effective tax rate. Alabama has no SDI or other state-level payroll taxes beyond income tax.
Tab "Compare Filing Status"
See your take-home pay calculated side-by-side as Single, Married Filing Jointly, and Head of Household. The comparison table shows federal tax, AL state tax, FICA, and net take-home for each status. Note that Alabama’s federal tax deduction interacts with filing status: MFJ filers typically have different federal tax than single filers, which changes the AL deduction amount.
The Formulas
Federal taxable income = Gross salary − Pre-tax deductions − Federal standard deduction
Single: $15,750 · MFJ: $31,500 · HoH: $23,500
Federal tax = Sum of (taxable income in each bracket × bracket rate)
Brackets: 10%, 12%, 22%, 24%, 32%, 35%, 37%
Step 2 — Alabama State Income Tax (uses federal tax as deduction):
AL taxable income = Gross − Pre-tax deductions − AL standard deduction − Personal exemption − Federal income tax paid
Standard deduction: $2,500 (single) / $7,500 (MFJ)
Personal exemption: $1,500 (single) / $3,000 (MFJ)
AL tax = Sum of (AL taxable in each bracket × rate)
Single brackets: 2% ($0–$500), 4% ($501–$3,000), 5% ($3,001+)
MFJ brackets: 2% ($0–$1,000), 4% ($1,001–$6,000), 5% ($6,001+)
Key: Alabama deducts your federal tax from state taxable income. This is computed iteratively — federal tax first, then used as a deduction for state tax.
FICA Taxes:
Social Security = 6.2% × min(Gross salary, $184,500)
Medicare = 1.45% × Gross salary
Additional Medicare = 0.9% × max(0, Gross − $200,000)
Take-Home Pay:
Net = Gross − Federal tax − AL tax − SS − Medicare − Pre-tax deductions
Per paycheck = Net ÷ Number of pay periods
Alabama is one of only 3 states (along with Iowa and Montana) that allow taxpayers to deduct federal income tax paid on their state return. This creates a unique circular dependency: your federal tax determines your state tax. The calculator resolves this by computing federal tax first, then applying it as a deduction for state purposes.
Example
$80,000 Salary — Single, Biweekly, No 401(k)
Without federal deduction (hypothetical): AL tax would be $3,760 — the Alabama deduction saves $452/year ($17/paycheck).
On an $80,000 salary in Alabama, you keep about 76.9 cents of every dollar. Your combined effective tax rate is 23.1%. Alabama’s low 5% top rate combined with the federal tax deduction makes it one of the more tax-friendly states for middle-income earners.
