Alabama Form 40V – Payment Voucher

Last reviewed: 2025-11-12

Use the Alabama Tax Form Calculator Form AL-40V: Alabama Form 40V – Payment Voucher as a stand alone tax form calculator to quickly calculate specific amounts for your 2026 Alabama state tax return. Alternatively, you can use one of our Combined Federal and State Tax Estimators to quickly calculate your salary, tax, and take-home pay.

Form AL-40V, titled “Individual Income Tax Payment Voucher,” is the official form used by the Alabama Department of Revenue (ADOR) for individual taxpayers to submit a payment when filing a return, amended return, or providing an automatic-extension payment. According to ADOR instructions, the voucher must accompany any check or money order when mailing in a payment tied to a paper return, unless paying electronically.

This voucher helps ADOR accurately apply your payment to the correct taxpayer, year, and form by including your Social Security Number(s), tax period, and the exact tax form being filed (Form 40, 40A, 40NR, etc.). Using the correct voucher minimizes processing delays and prevents misallocations of payments.

How to Complete Alabama Form 40V

Taxpayer information: Enter the primary taxpayer’s SSN, spouse’s SSN (if joint), full names, mailing address, telephone number, and the tax period (e.g., 12-31-2026). Ensure that all identifying details match your Form 40 or Form 40A submission.
Select payment purpose: Indicate whether the payment accompanies your original return, an amended return (Form 40X), or an automatic extension request. The box selection determines how the Alabama Department of Revenue (ADOR) will apply your payment to your account.
Payment amount: Enter the exact dollar amount you intend to pay in the “Amount Due” field. Use whole dollars and cents (e.g., 1250.00). If you are filing electronically or paying through the My Alabama Taxes (MAT) portal, do not mail this voucher — online payments automatically apply to your tax account and generate confirmation receipts.
Detach and mail voucher: After completing the top portion, detach the voucher along the perforation and include it with your check or money order payable to Alabama Department of Revenue. Do not staple or tape the payment, voucher, or your return together. Mail the voucher and payment to:
Alabama Department of Revenue
P.O. Box 327485
Montgomery, AL 36132-7485
Electronic payment option: Taxpayers preferring online payment can use My Alabama Taxes (MAT) to remit via bank draft or card. In this case, the 40V is not required.

Important Notes & Deadlines

The due date for a payment using Form 40V aligns with the due date of your return (typically April 15 for calendar-year filers) or the automatic extension date if filing on extension. Late payments incur interest and penalty under Alabama law.

Always ensure the payment voucher identifies the correct year, SSNs, and form type. Incorrect or missing information can delay processing and potentially lead to misapplied payments or receipt of assessment letters.

If you are paying with a check or money order, write your Social Security Number on the memo line and include a separate check for each tax year if making multiple year payments. Avoid combining multiple years on one check unless explicitly directed.

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.
