A certified letter from the Louisiana Department of Revenue is almost always a formal notice of assessment: the state has calculated a specific amount of tax, penalty, and interest it says you owe, and it is using certified mail to create a verifiable record that you were told.1Justia. Louisiana Revised Statutes Title 47 RS 47-1565 – Notice of Assessment From the date on that letter, you have 60 calendar days to pay the amount or file an appeal. Let that deadline pass and the assessment becomes final, which means the Department can start seizing bank accounts, wages, and property without going to court.
What the Letter Is Telling You
The Department uses certified mail when a notice carries legal consequences and it needs proof of delivery. The most common reason is a formal notice of assessment, but you may also receive a certified demand for payment on a balance that was already assessed, or notice that enforcement action is coming.
In most cases, the certified letter is not the first contact. The Department usually sends a preliminary notice by regular mail first, giving you 30 days to resolve the issue before it formally assesses the amount.2Justia. Louisiana Revised Statutes Title 47 RS 47-1562 – Determination and Notice of Amount of Tax Due If that window closed without a response, the certified letter is the follow-up.
The underlying trigger is usually one of a handful of things: an unfiled return, underreported income, an unpaid balance, or an error the Department caught in an audit or automated review. The letter itself will identify the tax type, the periods involved, the amount broken into tax, penalty, and interest, and the deadline for responding. Read every line before you do anything else and check those details against your own records.
The 60-Day Deadline
You have 60 calendar days from the date on the certified assessment notice to do one of two things: pay the full amount, or file an appeal with the Louisiana Board of Tax Appeals.1Justia. Louisiana Revised Statutes Title 47 RS 47-1565 – Notice of Assessment A third option exists if you have the cash on hand: pay the amount under protest and then sue to get it back.
The 60-day period is not flexible. Once it passes, the assessment is final, you lose your right to challenge the amount at the Board of Tax Appeals, and collection can begin immediately.1Justia. Louisiana Revised Statutes Title 47 RS 47-1565 – Notice of Assessment Most people who end up in serious trouble with the Department got there by setting the letter aside, intending to deal with it later, and running out the clock.
What to Do This Week
Pull the records for the tax periods listed on the notice. If the Department says you didn’t file a return you know you filed, find your proof of filing. If the amount looks wrong, compare it line by line against what you reported.
If the assessment is correct and you can pay it, pay it inside the 60 days. That stops additional penalties and interest from piling on.
If you disagree with the amount, or you need more time to figure out whether you disagree, start the appeal to the Board of Tax Appeals before the deadline. You can refine your arguments after filing; what you cannot do is file late.
Keep records of everything. Save the certified mail receipt. Send any correspondence back to the Department by certified mail so you have your own proof. If you need to buy time while you gather documents, make contact in writing to acknowledge the notice. Silence looks like disregard.
What Happens If You Ignore the Letter
After the 60 days run out, the Department can collect by distraint and sale. That phrase covers a wide range of powers: seizing and selling personal property, levying bank accounts and securities, garnishing wages, and going after real estate.3Louisiana Department of Revenue. Cash Seizure No court order is needed. The final assessment itself is the legal basis for collection.
Interest keeps running the whole time. Louisiana charges interest at three percentage points above the state’s judicial rate, adjusted each calendar year.4Louisiana State Legislature. Louisiana Code RS 47-1601 – Interest For 2025 the combined rate was 11.25% annually. A $5,000 balance quietly adds more than $560 a year before penalties are counted.
Filing an appeal inside the 60-day window stops collection. The Department has to wait until the Board of Tax Appeals, or the last court to review the matter, issues a final decision.1Justia. Louisiana Revised Statutes Title 47 RS 47-1565 – Notice of Assessment That protection only exists if you file on time.
How the Appeal Works
The Board of Tax Appeals is an independent body that hears disputes between taxpayers and the Department. Filing a petition there within 60 days both pauses collection and gives you a formal forum to argue the amount down or out.1Justia. Louisiana Revised Statutes Title 47 RS 47-1565 – Notice of Assessment
The petition has to be in writing, organized in numbered paragraphs of fact, and must state what you want the Board to do. Attach a copy of the assessment notice and include your phone number, mailing address, and email. If you aren’t filing electronically through eFileLA, you need the signed original plus three copies.5Louisiana Board of Tax Appeals. FAQ
Filing fees scale with the amount in dispute:
- Under $10,000 in an assessment appeal: no fee
- $10,000 to $50,000: $300
- Over $50,000: $450, plus $40 per additional party served
If you owe a fee and forget to include it, the Board sends a notice giving you 60 more days to pay. Miss that second deadline and your petition is dismissed and the debt goes to the Office of Debt Recovery.5Louisiana Board of Tax Appeals. FAQ The Board honors a mailbox rule, but only for official U.S. Postal Service postmarks, so keep your proof of mailing.6Louisiana Board of Tax Appeals. Rules and Regulations of Procedure and Practice
Paying Under Protest
If you don’t want to wait on the Board process, you can pay the full assessed amount, including tax, interest, and penalties, and challenge it on the back end. To use this route, you have to give the Department written notice at the time of payment that you intend to file suit in district court or a petition with the Board of Tax Appeals.7Justia. Louisiana Revised Statutes Title 47 RS 47-1576 – Remittance of Tax Under Protest
The payment goes into an escrow account for 30 days. You have those 30 days to file. If you miss the window, the Department keeps the money.7Justia. Louisiana Revised Statutes Title 47 RS 47-1576 – Remittance of Tax Under Protest This path requires having the cash available, which makes it impractical for many taxpayers, but it prevents any collection activity while you fight.
If You Agree You Owe but Can’t Pay
Louisiana allows installment agreements. The Secretary of Revenue is authorized to set them up and will look at your ability to pay in deciding whether to approve one.8Legal Information Institute. Louisiana Admin Code Title 61 I-4919 – Installment Agreement for Payment of Tax Interest keeps accruing on the unpaid balance, so the total paid will exceed the original assessment.
For real financial hardship, there is an offer in compromise program under R.S. 47:1578(4). The Secretary can accept less than the full amount, but only in narrow circumstances: serious doubt the Department could actually collect the debt, serious doubt that you truly owe the amount assessed, or a situation where the cost of collecting would exceed the balance.9Louisiana Department of Revenue. What Relief Is Available for Financial and Personal Hardships If your situation doesn’t clearly fit one of those three, expect a denial.
Check Whether the Assessment Is Even Timely
Louisiana generally has three years to assess additional tax after December 31 of the year you filed your return.10Louisiana State Legislature. Louisiana Code RS 47-1580 – Prescription A 2023 return filed in April 2024 starts the clock on December 31, 2024, giving the Department until December 31, 2027, to send an assessment. When your letter arrives, check the tax periods against this window. An assessment for a period outside the three years can be a strong appeal argument.
The important exception: if you never filed a return at all, there is no time limit. The Department can assess an unfiled year whenever it gets around to it. Fraud or substantial underreporting can also extend the period.
Asking for a Penalty Waiver
If the delinquency came from something other than negligence, the Secretary of Revenue can waive some or all of the delinquency penalties. The request has to be in writing and has to explain what happened. The statute doesn’t define “reasonable cause,” but a few situations create a presumption in your favor: a valid extension where you paid at least 90% of what you owed by the original due date and paid the rest with the return, or a federal adjustment where you filed an amended Louisiana return within 90 days.11Louisiana State Legislature. Louisiana Code RS 47-1603 – Waiver of Penalties Interest is not waivable under this provision, only the penalties.
