Louisiana Tax Payment Plan Calculator

How Louisiana Tax Payment Plans Work

In Louisiana, the Louisiana Department of Revenue (LDR) lets qualifying taxpayers request an installment agreement; informal agreements run up to 60 months for balances under $50,000, while formal agreements — which require a complete financial statement — apply to balances of $50,000 or more or terms beyond 60 months. Interest accrues on unpaid taxes at 10.50% annually in 2026 (three points above Louisiana's judicial interest rate), and a nonrefundable $105 installment agreement fee applies unless your adjusted gross income is $25,000 or less. Because interest keeps accruing the whole time, the largest payment amount you can sustain is usually the cheapest path — the calculator above shows that trade-off for your exact balance.

The cost most people miss: a payment plan stops aggressive collection actions, but it isn't free — LDR keeps charging interest and delinquent payment penalties on whatever you still owe. Paying even a little more each month can save money in total.

What's Specific to Louisiana

Is a Payment Plan Your Best Option?

A Louisiana installment agreement isn't always the cheapest path. Here's how it compares to the other ways to resolve a tax bill in Louisiana:

Before You Apply Online

Consider getting tax help before applying on your own if:

• You can't pay a monthly payment amount that fits within the agreed term.
• Your balance exceeds Louisiana's informal agreement threshold of $50,000.
• You have missing or unfiled Louisiana tax returns.
• You already defaulted on a prior installment agreement.
• You've received a levy, garnishment, or lien notice.
• You owe both Louisiana state tax and federal tax balances.
• Your business collected sales tax or withholding tax.
• Your income is unstable or has recently reduced.

Applying online with the wrong setup can lock you into an unaffordable payment amount or cause you to miss a more cost-effective tax resolution option.

Common Mistakes With Louisiana Payment Plans

• Choosing a monthly payment too low to pay the tax balance down within the agreed term
• Forgetting that LDR keeps charging interest, while delinquent payment penalties cap at 25%, but individual income tax penalties can take years
• Falling out of compliance — a new unfiled or unpaid return resulting in a defaulted plan
• Missing a single payment and defaulting on the whole installment agreement
• Setting up a plan before filing missing income tax returns — LDR generally won't approve a plan with unfiled returns outstanding
• Setting up a Louisiana state tax plan without coordinating an IRS installment agreement if you also owe federal tax
• Assuming a payment plan automatically removes a state tax lien, levy, or garnishment
• Not asking about a penalty waiver before locking into a long-term payment plan

How to Apply in Louisiana

Apply online through LaTAP at latap.revenue.louisiana.gov, by phone with the Collection Division at (855) 307-3893, or by mailing Form R-19026 (individual) or R-19027 (business). The calculator is an estimate to help you pick a payment amount before you apply; LDR sets official terms and may require a financial statement for larger balances or formal agreements.

Does Louisiana offer a tax payment plan?

Yes, the Louisiana Department of Revenue (LDR) offers installment agreements that let individuals and businesses pay state tax debt over time. Balances under $50,000 with terms up to 60 months qualify for an informal agreement; larger balances or longer terms require a formal agreement with full financial disclosure. You can apply online through LaTAP, by phone, or by mailing Form R-19026 or R-19027.

In Louisiana, how long can a payment plan last?

Most Louisiana installment agreements run up to 60 months, provided the balance owed is under $50,000; the minimum term is six months. If you owe $50,000 or more, or need longer than 60 months, LDR requires a formal agreement supported by a complete financial statement, and the secretary may set a shorter term based on your ability to pay.

Does Louisiana keep charging interest during a payment plan?

Yes, LDR charges interest on unpaid taxes at a rate set annually — 10.50% in 2026 — and interest continues accruing on the remaining balance for the entire life of the agreement. Delinquent payment penalties also apply and can reach 25% of the tax due. Paying more than the minimum each month reduces total interest, which is exactly what the calculator above helps you plan for.

What's the minimum monthly payment in Louisiana?

LDR doesn't set one fixed dollar minimum for every account; instead, your payment must be large enough to retire the balance within the agreed term, generally between six and 60 months. LDR generally always requires the entire balance divided into six equal monthly minimum payments. If you can't afford a qualifying payment, ask LDR's Collection Division about alternative resolution options.

What happens if I miss a payment in Louisiana?

Missing a single installment puts your entire Louisiana agreement in default: the full outstanding balance becomes due and payable immediately once LDR issues notice and demand, and all collection actions — including liens, levies, and garnishments — can restart right away. You may request reinstatement, but LDR charges a mandatory $60 fee, or a new $105 fee if the lapse exceeds ninety days.

Will Louisiana still file a lien if I'm on a payment plan?

Yes, it's possible. LDR regulations allow tax liens to be filed in any parish where the department believes you own immovable property, even while an installment agreement is active. Taxpayers must also notify LDR before selling, encumbering, or otherwise disposing of real or personal property covered by the agreement. A lien can affect your credit and doesn't automatically get released just because you're making payments.

Is a payment plan my best option?

No, it's not always the best option. A Louisiana installment agreement helps if you can afford steady monthly payments and stay current on future filings, but interest and penalties keep accruing the whole time. If your balance is large relative to your income, penalty waiver requests, an offer in compromise, or hardship status may cost less overall. If you owe both LDR and the IRS, coordinate both agreements before committing to either one.

Do I need to file my returns before a payment plan in Louisiana?

Yes, LDR requires you to be current on filing every return and paying every liability not covered by the agreement before it will approve an installment plan, and you must keep filing and paying on time for the life of the agreement. Applying with unfiled returns typically leads to denial or delay. File any missing Louisiana returns first, then request your payment plan.
