Is the Louisiana Franchise Tax Really Repealed in 2026?

Louisiana lawmakers passed Act No. 6 (House Bill 3) during the November 2024 special session. Governor Jeff Landry signed it on December 4, 2024. As a result, the franchise tax disappears for periods beginning on or after January 1, 2026. This measure repealed La. R.S. 47:601 through 618. In plain terms, this means your business owes no new franchise tax starting in 2026.

The franchise tax was a major revenue source for the state. It raised roughly $570 million in its final year. Therefore, the repeal represents one of the largest business tax cuts in recent Louisiana history. Understanding the new Louisiana franchise tax rules helps you plan smarter for the year ahead. You can confirm the official status directly on the Louisiana Department of Revenue website.

Who Paid the Franchise Tax Before the Repeal?

The franchise tax applied to specific entity types. Business owners should know whether their company owed it historically. The tax covered the following entities:

• Domestic corporations organized under Louisiana law.
• Foreign corporations qualified to do business in the state.
• LLCs that elected corporate tax treatment with the IRS.

By contrast, partnerships and disregarded-entity LLCs did not owe the franchise tax. Consequently, your entity classification determines your historical exposure. Many business owners benefit from reviewing their business entity structure after this change.

What Tax Applies Now Instead?

The franchise tax repeal did not touch the corporate income tax. For periods beginning on or after January 1, 2025, Louisiana applies a flat 5.5% corporate income tax rate. Therefore, corporations still file and pay income tax even without franchise tax. Many Louisiana business owners find value in professional help navigating these overlapping rules. A trusted tax preparation partner in Louisiana can guide your filings.

Do I Still Owe Louisiana Franchise Tax From Prior Years?

This point confuses many business owners. The repeal applies only to future periods. It does not forgive any past franchise tax debt. As a result, unpaid balances from 2025 and earlier remain fully collectible. Furthermore, penalties and interest continue to accrue on those balances. The state can still audit and assess prior periods.

Therefore, do not assume the repeal wipes your slate clean. Instead, review your filing history carefully. If you skipped a franchise tax return, you should resolve it now. Working with a professional for tax preparation and filing can reduce stacking penalties. For federal guidance on related business filings, review the IRS small business resources.

Why Prior Liabilities Survive the Repeal

Tax repeals rarely apply retroactively. Louisiana structured Act No. 6 to end future liability only. Consequently, the state preserves its right to collect past-due amounts. This approach protects the revenue already owed. Business owners who ignore this risk severe consequences, including liens.

Steps to Resolve Outstanding Franchise Tax

If you still owe prior franchise tax, follow a clear plan. These steps help limit your exposure:

• Confirm your entity classification for each prior year.
• Gather records for any unfiled franchise tax periods.
• File all delinquent returns promptly to stop penalty growth.
• Calculate penalties and interest using current rates.
• Contact the state about possible payment plans.

How Do You Calculate Louisiana Franchise Tax Penalties?

The penalty structure is precise and stacked. Under La. R.S. 47:1602(A)(1), the delinquent filing penalty is 5% of the tax due. It applies for the first 30 days, then another 5% for each additional 30 days. The same applies to delinquent payment under subsection (A)(2). In plain terms, this means late filing and late payment each build separate penalties.

However, La. R.S. 47:1602(A)(5) caps the combined penalties at 25%. Therefore, your maximum penalty exposure is 25% of the tax due. In addition, interest accrues separately. For 2026, the interest rate is 10.50%, per Revenue Information Bulletin No. 26-001. This is down from 11.25% in 2025. Louisiana business owners can estimate their total tax picture using our Small Business Tax Calculator for Louisiana to plan for 2026.

Penalty and Interest Rate Table

The table below shows the key rates. Compare the 2025 and 2026 interest figures:

Charge Type	2025 Rate	2026 Rate
Delinquent filing penalty	5% per 30 days (25% cap)	5% per 30 days (25% cap)
Delinquent payment penalty	5% per 30 days (25% cap)	5% per 30 days (25% cap)
Annual interest rate	11.25%	10.50%

A Worked Penalty Example

Suppose a corporation owed $10,000 in franchise tax for a prior period. It filed and paid 45 days late. The filing penalty covers two 30-day periods, so 10% applies. The payment penalty also covers two periods, adding another 10%. Together, that totals $2,000 in penalties. In addition, 2026 interest at 10.50% accrues on the unpaid balance. Consequently, early resolution saves real money.

Which Forms Do You Use After the Repeal?

The repeal changed Louisiana’s corporate forms. Previously, the combined form was CIFT-620. That form handled both income and franchise tax together. Because franchise tax ended, the state renamed the form CIT-620. The estimated payment voucher is now CIT-620ES. Therefore, the form name now reflects income tax only.

However, you may still need the older CIFT-620 for prior franchise tax periods. In addition, the e-filing mandate continues. Corporations with $250,000 or more in total assets must file electronically. Working with a professional for business financial systems keeps these filings organized. For general federal filing guidance, consult IRS forms and instructions.

Form Transition Comparison

This table clarifies the old and new forms:

Purpose	Old Form	New Form (2026)
Corporate return	CIFT-620	CIT-620
Estimated payments	CIFT-620ES	CIT-620ES

Key Terms Defined

These definitions help you apply the rules correctly:

• Disregarded entity: An LLC the IRS treats as part of its owner.
• Qualified to do business: A foreign corporation registered to operate in Louisiana.
• E-filing mandate: A legal requirement to submit returns electronically.

What Other 2026 Louisiana Tax Changes Should You Know?

The franchise tax repeal is not an isolated event. It sits inside a larger 2025 to 2026 reform package. Therefore, business owners should view the full picture. Louisiana adopted a 3% flat individual income tax rate. Moreover, the corporate income tax moved to a flat 5.5% rate. These changes aim to simplify the state’s tax code.

In addition, the statewide sales and use tax increased to 5%. The sales tax base now includes certain digital goods and services. Furthermore, a 2% business utility sales tax applies. As a result, your overall tax mix may shift even as franchise tax disappears. High earners and complex entities may benefit from advanced wealth and tax strategies.

Reform Timeline at a Glance

This list summarizes the major moving parts:

• Flat 3% individual income tax rate now applies statewide.
• Corporate income tax uses a flat 5.5% rate.
• Franchise tax repealed for periods starting January 1, 2026.
• Statewide sales and use tax rose to 5%.
• Digital goods and services now fall under sales tax.

Storm-Related Federal Relief

Separately, the IRS granted relief to Louisiana taxpayers affected by Tropical Storm Arthur in 2026. Estimated payments originally due on or after June 17, 2026, were postponed through November 2, 2026. Therefore, affected businesses avoided certain penalties. You can review the details on the IRS newsroom page. This relief applies to federal obligations, not state franchise tax.

 

 

Uncle Kam in Action: A Louisiana LLC Owner

Here is a hypothetical example of how this works in practice. Consider a marketing agency in Baton Rouge structured as an LLC. The owner elected corporate tax treatment with the IRS in 2022. Therefore, the company owed franchise tax for several prior periods. However, the owner missed two franchise tax filings before the 2026 repeal.

The Challenge: The owner assumed the 2026 repeal erased all franchise tax debt. In reality, the repeal only ended future liability. The company still owed roughly $8,000 in franchise tax for 2024 and 2025. Meanwhile, penalties and interest kept growing each month.

How Uncle Kam Would Approach It: First, we would confirm the entity classification for each year. Next, we would gather records and prepare the delinquent returns. Then, we would calculate penalties under the 25% cap rule. Finally, we would apply the 2026 interest rate of 10.50% to project the balance.

Illustrative Numbers: Assume the $8,000 balance sat 90 days late. The filing penalty could reach 15%, and the payment penalty another 15%. However, the combined cap limits penalties to 25%, or $2,000. By filing immediately, the owner could save roughly $600 in avoided additional penalty tiers. Furthermore, stopping the clock limits future 10.50% interest. This estimate shows why prompt action matters.

This example is illustrative only. Still, it mirrors a common post-repeal mistake. You can read real outcomes on our client results page. Proactive planning turns confusion into a clear compliance path.

Next Steps

The repeal simplifies your future, but prior obligations demand attention now. Many Louisiana business owners rely on a local Louisiana tax preparation team to handle the transition. Take these actions today:

• Review your entity classification for every prior franchise tax year.
• File any delinquent franchise tax returns immediately.
• Switch to the new CIT-620 forms for current filings.
• Book a tax advisory consultation to plan for 2026.
