Louisiana Tax Extension: Deadlines, Rules and More

Tax season can be hectic, but Louisiana makes it easy to file an extension if needed. Follow these steps to get more time to file your state return and avoid penalties.

But remember, an extension delays your filing deadline, not your payment deadline. Louisiana requires all taxes owed to be paid by the original due date to avoid penalties and interest.

This covers everything you need to know about filing a Louisiana tax extension, including eligibility, deadlines, payment options, and FAQs.

Louisiana Tax Extension Rules

What is an Extension?

A Louisiana tax extension gives you more time to file your state income tax return. Individual taxpayers get an automatic extension, and the filing deadline is moved to November 15.

Important Notes:

• An extension delays the filing deadline, not the payment deadline.
• Late payments are subject to 10.50% annual interest and a 0.5% penalty every 30 days (up to 25%).

How to File a Louisiana Extension

Here’s how to file a Louisiana extension and meet state requirements:

Step 1: Meet Eligibility

To qualify for an extension, you must have all estimated taxes paid by the original due date, which for individual taxpayers is May 15th.

Examples:

• Example 1: If your estimated tax liability is $10,000 and you’ve already paid $8,000 through withholdings, you must pay $2,000 by May 15th.

Step 2: File the Right Form

• No form is required. Louisiana grants an extension for individual taxpayers automatically.

Step 3: Pay Taxes Owed

Calculate your total tax liability, subtract any payments made, and pay the balance by the original due date.

Example:

If your total tax liability is $15,000 and you’ve paid $12,000, you must pay $3,000 to avoid penalties.

Online Payment - Bank Account:

• Head to the Louisiana Taxpayer Access Point and click the "Make a Payment" link. It allows you to pay your taxes or make an extension without logging into an account.
• You will need to provide your Social Security number, first and last name, and bank account information.
• Choose Extension Payment and follow the instructions.

Online Payment - Credit or Debit Card

• Submit payment via the Louisiana Department of Revenue Payment Portal.

By Mail:

• Complete R-2868V, Individual Income Tax 2025 Automatic Extension Payment Voucher, and attach it to your money order or check.
• Make checks payable to “Louisiana Department of Revenue” and include the last four digits of your Social Security number on your check.
• Mail to:
  Louisiana Department of Revenue
  P.O. Box 3550
  Baton Rouge, LA 70821-3550.

Step 4: Save Your Documents

Keep copies of your payment confirmation, federal extension (if applicable), and any Louisiana forms filed.

Don’t Make These Mistakes

1. Not Making a Payment: Extensions only delay filing deadlines, not payment deadlines.
2. Missing the May 15th Deadline: Payments must be postmarked by these dates to avoid penalties.
3. Underestimate Your Amount Due: It’s better to overpay and get a refund than to underestimate and get penalties.
