Form AL-40A is the short form individual income tax return for Alabama residents who meet eligibility criteria for simplified filing. It’s intended for taxpayers with wages, salaries, interest, and limited adjustments, and who do not claim complex credits, itemized deductions, or business income. Most filers eligible for this form can complete their Alabama return using standard deductions and personal exemptions without attaching multiple schedules.
This form mirrors the federal return structure but simplifies calculations by excluding self-employment income, rental activity, and capital gains schedules. The AL-40A short form provides an efficient way for full-year Alabama residents to comply with state tax obligations when their income and deductions fall within standard limits.
How to Complete Alabama Form 40A
- Enter Personal Information: Include your full name, address, Social Security number, and filing status. Only full-year Alabama residents may use Form 40A.
- Report Income: Transfer your total wages, salaries, tips, and taxable interest. This form is designed for basic income sources only—no business or rental activity.
- Adjustments and Deductions: Alabama allows a standard deduction automatically based on your filing status. Enter eligible adjustments, such as federal tax refunds or qualified educator expenses, where applicable.
- Tax Calculation: The tax rate table and standard deductions are applied automatically to your taxable income to compute total tax owed.
- Credits and Payments: Include any Alabama tax withheld from your W-2s, estimated tax payments, or other prepayments made throughout the year.
- Determine Refund or Amount Due: Subtract payments and credits from total tax. If overpaid, you’ll receive a refund; if underpaid, remit payment with the attached Form 40V payment voucher.

Example
Example: John and Sarah, married and living in Montgomery, earned $72,000 in wages and had $2,000 withheld in Alabama state tax. After applying the standard deduction and exemptions, their Alabama tax due is $1,950. Since they withheld $2,000, they will receive a $50 refund.

Frequently Asked Questions
What happens if Form AL-40X shows that I owe additional Alabama tax?
If your amended return results in a higher tax liability, you should pay the additional amount when you file AL-40X. Interest on underpaid tax generally accrues from the original due date of the return, not the date you amend, so delaying payment only increases the final cost. If you are mailing a check, Alabama recommends using a payment voucher such as Form AL-40V or AL-40NRV, depending on whether you are a resident or nonresident, so that your payment is correctly tied to the amended year and account. Failure to settle the extra liability can lead to billing notices, further interest, and potential collection actions. Even so, voluntarily amending and paying usually results in a better outcome than waiting for Alabama or the IRS to discover discrepancies.
What records should parents keep to support a Schedule AATC claim?
Parents should retain invoices, tuition bills, proof of payment (bank statements, receipts), enrollment confirmations, and school documentation proving entry into the non-failing or nonpublic school. The Alabama Accountability Act requires strict substantiation to prevent misuse, so taxpayers should also keep the school’s classification documents or confirmation that the original school appeared on the “failing school” list for the appropriate year. If audited, the Alabama Department of Revenue may request these records to validate the refundable credit. While documents are not mailed with the return, they should be kept for at least three years.
How can I estimate my Alabama tax before using Form 40A?
You can preview your expected liability with the Alabama State Tax Calculator. It uses current rates, thresholds, and personal exemptions to show how much tax you’ll owe or be refunded. This is especially useful if you are switching from the full Form 40 or adjusting withholding.
Who must file Alabama Form AL-40NR and how does it differ from the resident Form AL-40?
Form AL-40NR is required for individuals who were not Alabama residents for the tax year, or who lived in the state only part-time, but earned income from Alabama sources. Unlike the resident Form AL-40, which reports all income from all sources, Form AL-40NR focuses on allocating income between Alabama and other jurisdictions. You must complete the return if you earned wages for work performed in Alabama, had rental property within the state, received income through a pass-through entity operating in Alabama, or sold property located in Alabama. Part-year residents must report income earned while domiciled in the state and any income sourced to Alabama thereafter. The AL-40NR also requires an allocation schedule to separate Alabama-sourced income from non-Alabama income, ensuring the correct proportion of tax is calculated. This prevents nonresidents from overpaying on non-Alabama income while still ensuring Alabama collects the correct amount on in-state activity.
Why don’t my brackets match payroll tables?
Employers may use different rounding/timing tables; small variances are normal.
