Uses Alabama's 2026 figures: 2%/4%/5% brackets (Single $500/$3,000 thresholds; Joint $1,000/$6,000), standard deduction (Single $3,000 · Joint $8,500 · Head of family $4,700), personal exemptions (Single $1,500 · Joint $3,000) and $300 per dependent. Alabama's standard deduction phases down at higher incomes — this uses the full amount as a simplified estimate. Federal tax deduction, credits and local taxes excluded. Educational estimate, not tax advice.

How it works

The calculator subtracts pre-tax deductions, the standard deduction (or your itemized amount if larger), and Alabama personal and dependent exemptions from gross income to get Alabama taxable income. It then walks the real 2026 bracket table — 2% on the first $500 ($1,000 joint), 4% on the next slice, 5% above $3,000 ($6,000 joint) — taxing each slice at its rate exactly the way Alabama computes it. Note that Alabama’s thresholds have not changed since 1982, so most earners reach the 5% bracket quickly.

Everyday uses

  • Alabama workers — estimate your state withholding and avoid an April surprise.
  • New residents — see what the move costs you in state tax before you relocate.
  • Freelancers — rough out quarterly Alabama estimated payments (Form 40ES).
  • Job changers — compare offers by real take-home, not headline salary.
  • Students — learn why Alabama’s “low” top rate still touches most paychecks.

Frequently asked questions

Why is my marginal bracket 5% when I don’t earn much?

Alabama’s 5% threshold starts at just $3,001 of taxable income ($6,001 joint) and hasn’t been adjusted since 1982 — so nearly every working adult has income in the top bracket.

Does this include federal income tax?

No — Alabama only, and the calculator excludes Alabama’s unusual deduction for federal income tax paid, so treat the result as a simplified estimate.

Is this tax advice?

No — it is an educational estimator using 2026 figures. Credits, other income, and special situations can change your real bill; a tax professional can advise on your situation.

Where is my data stored?

Nowhere. The calculation runs in your browser and the numbers vanish when you close the tab.
