Alabama Tax Tables
Alabama Tax Tables provide a complete reference of how state income tax is calculated for each supported year. These tables summarise the official rules issued by the Alabama Department of Revenue and present them in a clear structure that matches the calculations used in our Alabama Tax Calculator. They are useful for checking withholdings, estimating liability, reviewing historical tax years and understanding how state policy shapes taxable income.

Select a tax year to view the official Alabama tax rates and rules used in our calculators. Each page shows the brackets or flat tax rate, deduction amounts, credit structures, withholding guidance and any year-specific updates published by the Alabama Department of Revenue. You can also access the matching Alabama Tax Calculator for precise calculations for that year.
How Alabama Calculates Income Tax
Alabama uses a progressive tax system where income is divided into brackets and each portion is taxed at its marginal rate. These rules determine how wages and other taxable income are assessed for Alabama returns, with updated tables released each year to reflect legislation and inflation changes. For a broader explanation of how tax tables work, see our Tax Tables guide.
Alabama supports resident, nonresident and part-year filing rules. The tax tables help clarify which thresholds apply when income is earned both inside and outside the state.
What Is Contained in the Alabama Tax Tables?
Each tax-year page provides a structured summary of the components Alabama uses to calculate individual income tax. While details vary by year, the state tax tables generally include the following elements:
- State tax brackets and marginal rates for each filing status.
- Standard deduction amounts for each filing status.
- Itemized deductions where permitted under Alabama law.
- Dependent and family-related credits including any child-based or filer-based reductions.
- Retirement income rules including partial or full exemptions for pensions or Social Security.
- State withholding tables used by employers for payroll calculations.
Together, these elements provide a transparent breakdown of how Alabama calculates tax for each year. This structure helps taxpayers review year-to-year changes, employers validate payroll withholding and financial planners analyse how Alabama’s rules differ from federal requirements. All values shown in our Alabama Tax Tables match the official figures published by the state.
Frequently Asked Questions
How does income allocation work for part-year residents filing AL-40NR?
For part-year residents, Form AL-40NR requires a two-step process: (1) report all income from all sources on the federal-equivalent side of the return, and (2) allocate only Alabama-sourced income into the Alabama column. Income earned while you were physically residing in Alabama is generally considered Alabama-sourced, regardless of employer location. Meanwhile, income earned while domiciled outside Alabama is Alabama-sourced only if the economic activity occurred within the state—such as performing work in Alabama, operating a business there, or earning income from Alabama property. Deductions must also be apportioned: some are fully allowed, while others (e.g., certain business expenses) must be split proportionally. Accurate allocation ensures the tax is calculated only on income legally attributable to Alabama. Completing this allocation carefully often prevents over-taxation and produces a fair representation of your Alabama tax liability.
What is Alabama Schedule ATP and when is it required?
Alabama Schedule ATP is used to calculate and report additional taxes and penalties that arise when certain tax conditions are not met. Unlike other schedules that compute income or deductions, Schedule ATP focuses on situations such as early withdrawal penalties on education savings accounts, repayment requirements for certain credits, penalties for failure to file or pay timely, and other special-case tax assessments defined under Alabama law. This schedule functions as a central place where all supplemental taxes must be disclosed to ensure the taxpayer’s Form AL-40 or AL-40NR accurately reflects total liability. Failing to include required ATP entries may lead to ADOR corrections, additional assessments, or interest charges. Because of this, Schedule ATP is an essential compliance document for taxpayers who triggered any mid-year disallowed benefits, timing-related penalties, or other exceptions.
Are HSA contributions pre-tax for Alabama?
Generally pre-tax federally and often for Alabama; confirm in the state section and add in the calculator.
What is Alabama Schedule DC used for?
Schedule DC allows Alabama taxpayers to claim a deduction for qualified dependent-care expenses that enable them to work or actively seek employment. These expenses may include daycare, after-school programs, in-home childcare, or care for a disabled spouse or dependent who cannot care for themselves. Alabama’s rules parallel many federal provisions but apply at the state-deduction level rather than as a credit. To use Schedule DC, both spouses must have earned income when filing jointly unless one spouse is disabled or a full-time student. The deduction is limited by earned income, the dependency status of the individual receiving care and Alabama’s maximum per-dependent limits. Proper documentation is required for all expenses.
How does Alabama treat passive activity losses and out-of-state pass-through income?
Alabama generally follows federal passive-activity rules but requires taxpayers to separately identify passive losses on Schedule E so they can be applied only where permitted. If you have losses disallowed at the federal level, they remain disallowed in Alabama unless the state provides a separate exception. For pass-through income earned in another state, Alabama requires residents to report the full amount, then claim any allowable adjustments or credits on other schedules such as Schedule CR. The Schedule E calculator prepares totals that flow into Alabama Form 40 so the correct taxable amount appears on the return.
