Alabama State Income Tax Brackets and Deductions (2026)

Alabama applies three progressive tax rates. Personal exemptions and a state standard deduction further reduce the income subject to tax.

Single Filers

Rate	Taxable Income Range	Tax Owed
2%	$0 –$500	2% of taxable income
4%	$501 –$3,000	$10 + 4$500
5%	$3,001 or more	$110 + 5$3,000

• State standard deduction: $8,500 if AGI is below$23,500; reduced by $25 for each additional$500 of AGI (minimum $2,000).
• Personal exemption: $1,500.

Married Filing Jointly

Rate	Taxable Income Range	Tax Owed
2%	$0 –$1,000	2% of taxable income
4%	$1,001 –$6,000	$20 + 4$1,000
5%	$6,001 or more	$220 + 5$6,000

• State standard deduction: $7,500 if AGI is below$23,500; reduced by $175 for each additional$500 of AGI (minimum $4,000).
• Personal exemption: $3,000.

How to Estimate Your Alabama Income Tax

Using the Alabama Tax Rate Calculator, you can follow these steps or let the tool compute everything automatically. Below is a step‑by‑step example for a single filer with an AGI of $100,000 living in Gadsden.

1. FICA Tax

FICA is withheld before other taxes:

$$\text{FICA} = 100{,}000 \times 7.65\% = \$7{,}650$$

2. Federal Income Tax

After the federal standard deduction ($16,100 for single filers) the taxable income is:

$$100{,}000 - 16{,}100 = \$83{,}900$$

Using the 2026 federal brackets, the tax owed is $5,800 plus 22$54,400:

$$5{,}800 + (83{,}900 - 54{,}400) \times 22\% = \$13{,}170$$

You can view a full bracket breakdown inside the Alabama Income Tax Calculator by switching the display to “Add federal income tax brackets.”

3. Alabama State Income Tax

Because the AGI ($100,000) far exceeds the$23,500 threshold, the state standard deduction drops to the $2,000 minimum. The personal exemption remains$1,500. State taxable income is:

$$100{,}000 - 2{,}000 - 1{,}500 = \$96{,}500$$

Since this falls into the 5% bracket, the tax equals:

$$110 + (96{,}500 - 3{,}000) \times 5\% = \$4{,}785$$

4. Local Income Tax

Gadsden imposes a 2% local tax on AGI:

$$100{,}000 \times 2\% = \$2{,}000$$

5. Total Tax and Take‑Home Pay

Summing all components:

$$7{,}650 + 13{,}170 + 4{,}785 + 2{,}000 = \$27{,}605$$

After‑tax income:

$$100{,}000 - 27{,}605 = \$72{,}395$$

If you use the tool’s payroll function and select monthly pay frequency, the estimated monthly take‑home is approximately $6,032.92.

Example for a Married Couple

Consider a married couple filing jointly with an AGI of $80,000 and no dependents, living in Bessemer.

1. FICA: 80{,}000 \times 7.65\% = \6{,}120$.
2. Federal tax: After the $32,200 federal standard deduction, taxable income is$47,800. The 2026 brackets apply: 10% up to $24,800 ($2,480) and 12% on the remainder ($23,000 × 12$2,760), for a total federal tax of $5,240.
3. State tax: Because the AGI exceeds $23,500, the state standard deduction is reduced to$4,000, and the personal exemption is $3,000. State taxable income:$80{,}000 - 4{,}000 - 3{,}000 = $73{,}000$. Using the joint bracket, tax =$220 + (73{,}000 - 6{,}000) \times 5% = $3{,}570$.
4. Local tax (Bessemer 1%): 80{,}000 \times 1\% = \800$.
5. Total annual tax: 6{,}120 + 5{,}240 + 3{,}570 + 800 = \15{,}730$. After‑tax income:$80{,}000 - 15{,}730 = $64{,}270$.
