Owing back taxes in Arkansas can escalate quickly. If you missed a quarterly due date, underpaid your estimated income tax, or filed your individual income tax return late, penalties and interest may be added to your tax liability. The Arkansas Department of Finance and Administration offers penalty abatement for taxpayers with reasonable cause. The DFA's Individual Income Tax Penalty and Interest Waiver Request form (rev. 12/8/2022) allows requests for failure to file penalty, failure to pay penalty, underpayment of estimated tax penalty, and interest, with qualifying reason categories that include illness, natural disaster, or other circumstances explained in detail.
To avoid penalties, Arkansas requires you to pay at least 90% of your current-year net tax liability throughout the tax year, or 100% of the taxes shown on last year's return if that return covered all 12 months. If you have uneven income, you may calculate your estimated payment using an annualized rather than a quarterly basis. A payment plan may allow the balance to be paid over time, but additional interest continues to accrue during the installment period, and a Certificate of Indebtedness may be filed as required by law.
Understanding how penalty amounts are determined, what interest may apply, and what documents to submit is key to securing penalty relief. This guide covers why penalties are assessed, how the combined maximum cap works, and how to request relief even if your initial attempt is denied.
In Arkansas, penalties are assessed when taxpayers fail to meet their obligations under state tax law. These charges are typically added when someone files their individual income tax return late, underpays estimated tax, or makes incorrect or incomplete payments throughout the tax year. The Arkansas Department of Finance and Administration has clear guidelines on how and when penalties apply. Understanding the most common reasons penalties are issued can help you avoid them or take action to request penalty relief if you qualify.
Late filing — When a taxpayer fails to submit an income tax return by the prescribed date and no extension has been granted, a failure to file penalty is imposed. This penalty may continue to grow each month until the return is submitted.
Late payment — If a person makes a payment after the due date without paying the tax shown on the return, interest will be imposed, and late fees will begin to accrue. Even if the return is filed on time, a delay in payment can trigger additional charges.
Underpayment of estimated tax — Arkansas requires you to pay at least 90% of your expected net tax liability for the year, or 100% of the tax paid in the preceding income year, provided that the return covered all 12 months. The state may impose an underpayment penalty if you fail to meet either threshold. Uneven income or missing a fourth-quarter installment often leads to such underpayment issues. You can use Form 2210 to help calculate whether an underpayment penalty applies to your situation.
Incorrect or insufficient payments — If a payment through an electronic funds transfer fails due to insufficient funds, a flat $20 fee is typically added to the existing penalty. Incorrect payment amounts or processing errors can also result in additional costs.
Intentional disregard or fraud — A taxpayer's failure to comply with filing or payment requirements due to intentional disregard may trigger criminal penalties under Arkansas law. In more serious cases, this includes prosecution and fines beyond the standard penalty abatement thresholds.
Once a penalty is assessed, the Arkansas Department may send a proposed assessment outlining the total amount due, including interest, fees, and any penalties for the taxpayer's failure to comply. In most cases, penalties and interest accumulate monthly until the full amount is paid. If your situation qualifies for penalty relief due to unusual circumstances, you can submit documentation showing reasonable cause and a good-faith effort to comply.
Being proactive is crucial. Understanding how penalty amounts are calculated and how they relate to your specific tax year can help you prevent future issues and take advantage of relief options available under Arkansas tax law.
The Arkansas Department of Finance and Administration enforces several penalties when taxpayers fall behind or make errors. These penalties typically apply when a person fails to file their tax returns on time, underpays their estimated income tax, or submits incorrect payments. In addition to the penalties themselves, interest on unpaid balances can add up quickly.
Each penalty is calculated based on specific percentages, but for ordinary failure-to-file and failure-to-pay penalties, the combined maximum cannot exceed 35% of your total tax liability. The type and severity of the penalty depend on the nature of the violation and how long it remains unresolved.
Failure-to-file penalty — 5% per month on unpaid tax, up to a maximum of 35%.
Failure-to-pay penalty — 1% per month on unpaid tax, up to a maximum of 35%.
Combined penalty cap — The combined failure-to-file and failure-to-pay penalties cannot exceed 35% of the tax due. This cap applies to ordinary filing and payment violations.
Interest — Arkansas charges interest at 10% per year on unpaid tax balances, beginning from the original filing deadline and continuing until the balance is paid in full.
Underpayment of estimated tax — A separate penalty may apply if estimated tax payments fall short of the required threshold. This is separate from the failure-to-pay penalty and is calculated based on the shortfall amount and timing.
$20 EFT fee — If a payment submitted via electronic funds transfer fails due to insufficient funds, a flat $20 fee is added on top of any other applicable penalties.
Arkansas also offers payment plans and, in appropriate cases, an Offer in Compromise to help taxpayers resolve outstanding liabilities. If you cannot pay in full, exploring these options early can help prevent further enforcement action, such as a state bank levy.
If a taxpayer fails to make a proper estimated payment — especially if their income varies — they may be penalized even if they pay taxes later. To avoid such a penalty, Arkansas requires that at least 90% of the net tax liability be paid during the tax year, or the same amount paid in the preceding year if that return covered all 12 months. If you earn most of your income later in the year, the state allows annualized basis calculations to assess estimated tax more fairly. Reviewing Form 1040-ES for estimated tax can help you plan accurate quarterly payments.
Other key considerations:
Whether you're filing your Arkansas tax return for the first time or catching up after a late payment, knowing your obligations can help you avoid unnecessary costs and stay compliant with state tax law.
When taxpayers fail to meet their obligations under Arkansas tax law, the penalties and interest imposed are calculated using specific formulas. These amounts depend on the type of violation, the overdue payment, and the tax shown on the income tax return for the tax year. Knowing how these calculations work can help you determine what you owe and what relief you qualify for.
Failure to file penalty — If you file your individual income tax return late, Arkansas charges 5% per month of the unpaid balance. This continues until the total reaches 35% of the tax due. The penalty starts accruing from the date prescribed by state law, even if the return is submitted just a few days late.
Failure to pay penalty — When a person makes payment after the deadline — even if the return is filed on time — a 1% penalty per month is imposed. Like the filing penalty, it can grow until it reaches 35% of the outstanding balance. The combined total of both penalties cannot exceed 35%.
Underpayment of estimated tax — The state may apply an underpayment penalty if you pay less than 90% of your current-year net tax liability or less than 100% of the tax paid in the preceding income year (provided that the return covered all 12 months). This often affects individuals with uneven income or those who miss a fourth-quarter installment. Arkansas allows an annualized basis to calculate such underpayment when income varies significantly across quarters. If you are unsure whether you owe an underpayment penalty, Form 2210 provides a structured way to assess your exposure.
Insufficient or failed payments — If your electronic funds transfer fails — for instance, due to insufficient funds — the state may add a flat $20 fee on top of any other penalties. Even if you later submit correct payments, such a fee remains unless abated.
Arkansas charges interest at 10% per year on unpaid balances. This interest starts from the original filing deadline and continues to grow until the full balance is paid in full. Interest relief is not automatic — the DFA waiver form allows a separate request for interest waiver, but DFA guidance states that generally interest and penalty charges will not be waived, and interest continues until the balance is paid in full. Even if your penalty is waived, interest on the original tax liability typically continues to apply.
If the taxpayer's failure was due to other unusual circumstances — such as a natural disaster or serious illness — Arkansas may grant penalty relief. The DFA's waiver form identifies illness, natural disaster, and other circumstances (with a detailed written explanation) as the recognized qualifying categories. For those with uneven income, calculating estimated payments on an annualized basis may reduce or eliminate penalties, especially if earnings increase sharply in the final quarter.
Criminal penalties under state tax law may still apply if intentional disregard or willful neglect is involved, including in cases where the taxpayer fails to meet basic filing duties.
To qualify for penalty abatement in Arkansas, the taxpayer's failure must result from other unusual circumstances, not negligence or intentional disregard. The DFA's waiver form recognizes three qualifying reason categories: illness, natural disaster, or other circumstances supported by a detailed written explanation. The person establishes eligibility by demonstrating reasonable cause and a genuine effort to comply under state tax law.
Penalty abatement in Arkansas operates differently from IRS penalty abatement, which has its own separate standards and procedures. If you have federal penalties in addition to state ones, the two processes must be handled independently.
Arkansas may approve penalty abatement if the taxpayer failed to comply due to unusual circumstances beyond their control. The DFA's waiver form recognizes illness, natural disaster, and other circumstances as qualifying reason categories, provided the taxpayer submits a detailed written explanation. Examples of circumstances that may fall under these categories include:
Medical emergencies — A serious illness affecting you or a family member during the tax year may justify delayed or missed payments or filing an individual income tax return. Supporting documentation, such as hospital or medical records, would be required.
Death in the family — The loss of a spouse or close relative near the quarterly due date or filing deadline may qualify if supported by a death certificate or obituary.
Natural disasters — Events such as floods, fires, or tornadoes that disrupted your ability to file or make correct payments may warrant relief under the natural disaster category recognized by the DFA.
Other documented circumstances — The DFA waiver form includes an "Other" category that allows taxpayers to describe circumstances not covered by illness or natural disaster. Any reason submitted under this category must be explained in detail and supported by documentation. Examples might include certain administrative errors, verified system failures not caused by the taxpayer, or other situations demonstrating good faith.
Each case requires specific tax year records and clear documentation linking the unusual circumstance to the taxpayer's failure to file or pay. Requests that lack supporting evidence or rely on vague explanations are unlikely to succeed. You may also find it helpful to review how penalty abatement appeals work at the federal level to understand how the documentation standards compare.
The Arkansas Department of Finance and Administration does not approve penalty abatement for reasons such as forgetting to file an income tax return, missing a quarterly due date, or being too busy with personal matters. Lack of understanding about estimated tax rules, using the wrong tax year, or failing to track quarterly obligations are not accepted grounds.
Overreliance on a preparer without documented proof of incorrect advice, prioritizing other bills over your tax liability, and vague claims of hardship without documentation will likely lead to denial. Software errors or failed electronic funds transfer attempts caused by internal issues, rather than circumstances beyond the taxpayer's control, are also ineligible.
To qualify under state tax law, the taxpayer's failure must be clearly tied to illness, a natural disaster, or other unusual circumstances documented in writing, and the request must demonstrate a good-faith effort to comply.
If you believe you qualify for penalty relief, Arkansas offers a formal way to request penalty abatement. The process involves gathering records, completing the proper form, and explaining your situation clearly. Following each step thoroughly increases your chance of approval and helps you avoid delays or rejections due to missing details.
Start by carefully reading the proposed assessment from the Arkansas Department of Finance and Administration. This notice will outline the tax year involved, the tax shown, and the penalties and interest imposed. Pay close attention to the compliance deadline stated on the notice. If you need to verify your prior filing history, you can request an Arkansas tax transcript or old return to confirm the details before proceeding.
To prove reasonable cause, you must include supporting evidence. Your documents will vary depending on your situation, but may include:
These records help demonstrate that the taxpayer's failure resulted from an illness, natural disaster, or other unusual circumstance and that they acted in good faith.
Download the Individual Income Tax Penalty and Interest Waiver Request form (rev. 12/8/2022) from the DFA's website. Complete it thoroughly, including:
Avoid vague responses like "life was busy" or "I forgot." Instead, use concrete, documented explanations tied directly to the penalty period.
You may use the space on the form or attach a separate letter. Include a timeline of events — what happened and when — a clear explanation of why you could not file or make correct payments, the steps you took to resolve the problem, and any payment plan you entered. If underpayment was due to uneven income and a fourth-quarter installment shortfall, explain how an annualized basis calculation applies to your situation.
Keep your explanation concise and factual. The state needs to see a reasonable connection between your circumstances and your failure to comply.
Once complete, send your materials through one of these options:
Mail — Arkansas Department of Finance and Administration, Individual Income Tax Section, P.O. Box 3628, Little Rock, AR 72203
Fax — 501-682-7692
Email — individual.income@dfa.arkansas.gov
Only submit copies — never original documents. Originals will not be returned.
Retain copies of the completed waiver form, your supporting documents, and any delivery confirmation. You may need these if the department requests more information or if your request is denied and you choose to pursue further options.
If you have not received a reply, call the number listed on your proposed assessment or contact the DFA at (501) 682-1100. Keep your records nearby in case the department requests clarification.
By submitting your request promptly and following these steps, you improve your chances of getting penalty relief, whether your balance stems from back taxes, a failed electronic funds transfer, or estimated payments that fell short of the required threshold. You can also use our IRS Penalty Abatement Calculator as a reference tool to better understand how penalty calculations work.
Submitting a penalty abatement request requires accuracy, timely action, and strong documentation. Many taxpayers are denied relief because of common missteps.
Incomplete forms — Leaving out tax year details, penalty type, or contact information can lead to automatic rejection. Always complete all fields, even if writing "N/A."
Vague explanations — Stating "I was sick" or "had financial issues" without tying the circumstances to the specific tax year and the taxpayer's failure will not meet reasonable cause standards. The explanation must be specific and documented.
Missing documents — Claims involving electronic funds transfer errors, illness, or other unusual circumstances need to be supported by verifiable, dated proof.
Invalid reasons — Forgetting a quarterly due date, prioritizing other bills over your tax liability, or not understanding estimated tax rules are not accepted qualifying grounds.
Original documents — Never send originals; submit copies only. Documents like prior income tax returns, medical records, or termination letters will not be returned.
Delays and no follow-up — Waiting too long or failing to follow up can hurt your credibility. Interest continues to accrue at 10% per year until the balance is paid in full, regardless of whether a waiver request is pending.
Once you submit your penalty abatement request to the Arkansas Department of Finance and Administration, the review process begins. Knowing what to expect can help you stay prepared, especially if the department requests additional information or clarification.
The DFA does not publish a specific response timeframe on its official materials. The review period may vary depending on the complexity of your case, the number of tax years involved, and whether your submission is complete. The department will contact you using the details on file if more records are needed to support your claim. During this time, interest at 10% per year continues to accrue on the unpaid balance.
When penalty relief is granted, you will receive written confirmation. Your account summary will reflect updates to the total due based on the penalties waived. Keep in mind, however, that interest relief is not automatic — the DFA waiver form allows a separate request for interest waiver, but the DFA's general position is that interest and penalty charges will not be waived, and interest continues until the balance is paid in full. Always review your updated account summary carefully after approval.
Abatement does not exempt you from future penalties. Continued compliance is expected for future income tax returns and estimated tax payments, especially if your income varies from year to year.
If your request is denied, the department will explain why it did not meet the standards for penalty abatement. You have a few options:
Submit additional documentation — If your request lacked necessary details, you can reapply and include stronger records. For example, a failed electronic funds transfer might need a bank letter or email showing the reason for the failure.
Protest a proposed assessment — Under the Arkansas Taxpayer Bill of Rights, taxpayers may protest a proposed assessment to the Tax Appeals Commission within 90 days. Note that this protest right applies to proposed assessments specifically — it is a separate process from a general waiver request denial. Review the notice carefully for instructions.
Enter a payment plan — If you cannot pay the full amount due, an Arkansas tax payment plan may help prevent further enforcement action while giving you time to resolve your debt. Be aware that interest continues to accrue during the installment period, and a Certificate of Indebtedness lien may be filed as required by law.
Until your full balance is paid or formally waived, interest will continue to build — even while you are waiting for a decision or gathering additional documentation. That is why it is important to act quickly, make correct payments when possible, and avoid further delays. Staying engaged during this process and responding to any request from the department demonstrates intent to comply, even when facing hardship or other unusual circumstances.
The DFA does not publish a specific response timeframe on its official materials. The review period will vary depending on the complexity of your case, whether multiple tax years are involved, and whether your submission is complete. During this time, interest at 10% per year will continue to accrue until your balance is either formally waived or paid in full. Follow up with the department directly at (501) 682-1100 if you have not received a response after an extended period.
A failed electronic funds transfer may support a penalty abatement request if you can document the reason for the failure. Include records such as bank letters or failed transaction documentation to support your claim. Note that the flat $20 EFT fee may still apply even if the underlying penalty is waived. Whether the failure qualifies for abatement will depend on the circumstances and the explanation provided on the waiver form.
Yes. Arkansas requires you to pay at least 90% of your current-year net tax liability — or 100% of the taxes shown on last year's return, provided that return covered all 12 months — to avoid an underpayment penalty. If your income varies throughout the year, accurately calculating your estimated payments using an annualized basis can help you stay compliant.
If you have uneven income — such as self-employment earnings that spike later in the year — you may qualify for reduced penalties by calculating your estimated tax using an annualized basis. This approach adjusts your estimated payment to reflect actual income earned each quarter and may help if you missed a fourth-quarter installment or underpaid earlier in the tax year. Reviewing the Form 2210 underpayment rules can help you determine whether this calculation method applies to your situation.
Not automatically. The DFA waiver form allows a separate request for interest waiver, but the DFA's general guidance states that interest and penalty charges will not typically be waived, and interest continues until the balance is paid in full. Always review your updated account summary carefully after any approval to confirm what, if anything, has been adjusted.
For ordinary failure-to-file and failure-to-pay penalties, the combined maximum under Arkansas law is 35% — these penalties cannot exceed that cap. If your total balance is still high, it may reflect accrued interest or an underpayment of the estimated tax penalty, which is calculated separately. You may still qualify for relief on the penalty portion if you can demonstrate that your failure was due to illness, a natural disaster, or other unusual documented circumstances.
Yes. If you cannot pay your full balance, you can request a payment plan through the Arkansas Department of Finance and Administration. Be aware that additional interest continues to accrue during the installment period, and a Certificate of Indebtedness lien may be filed as required by law. You may also submit a penalty abatement request while enrolled in a plan — just be sure to document all payments made and any actions you have taken to comply.
