Filing a 2013 Louisiana state income tax return requires understanding the specific rules, deadlines, and forms set by the Louisiana Department of Revenue. For this tax year, residents were required to use Form IT-540 to complete the process. Taxpayers who earned wages, received income from Louisiana sources, or had state tax withheld needed to present a return, even if they were not required to file at the federal level. Knowing how to file a Louisiana state tax return for tax year 2013 is essential for individuals who want to recover overpaid taxes, claim available tax credits, and avoid unnecessary interest or penalties.

The process of completing an income tax return involves careful attention to details such as social security number accuracy, deductions, and proper schedules. Joint filers must report combined income, dependents, and spouse information, while single individuals follow separate filing rules. Many taxpayers also needed to explore estimated payments made during the current year to determine whether additional payments were required. Filing by the correct date was critical because late filing could generate a notice, delay refunds, or increase the balance due.

By following the official guidance, taxpayers could qualify for credits such as the child and dependent care credit or education-based programs. Millions of individuals file Louisiana tax returns every year, and the department continues to provide updated resources to help residents complete the process. Taxpayers can visit the official Louisiana Department of Revenue website at revenue.louisiana.gov or check IRS.gov for federal filing information that affects their state return.

How to File a Louisiana State Tax Return for Tax 2013 

Who Must File and When

Every resident of Louisiana for the 2013 tax year was required to complete Form IT-540, also known as the Louisiana Resident Income Tax Return. Individuals had to file if they earned income, had Louisiana income tax withheld, or wanted to recover payments that exceeded their actual liability. Even taxpayers who were not required to submit a federal return still needed to file a state return if Louisiana wages were reported. Joint filers were expected to present both incomes on the same return, including dependent information, age qualifications, and spouse details. The original filing date for the 2013 Louisiana return was May 15, 2014. Taxpayers who filed after this date could expect to pay interest and penalties unless an extension was granted correctly. Those who created estimated payments during the current year needed to apply them to reduce their balance due.

Required Forms and Schedules

The primary form for this process was IT-540, which included several schedules depending on the taxpayer’s situation. Schedule E covered adjustments to income, Schedule F listed refundable credits, and Schedule G identified nonrefundable credits. Other schedules were available for donations and deductions. Taxpayers had to ensure that every page of the return was completed, signed, and submitted to the correct address of the Louisiana Department of Revenue. The department provided multiple ways to access these materials, including downloadable PDFs, online web forms, and mailed booklets. Individuals were encouraged to visit revenue.louisiana.gov to obtain the correct version. Each form required accurate entry of the social security number, home address, and date to ensure processing.

Common Mistakes to Avoid

Many errors occurred during the filing process, which caused delays or rejection of returns. A frequent mistake involved incorrectly entering the taxpayer’s social security number or spouse's information. Others forgot to claim eligible deductions or failed to include proof for the income or dependent care credit. Some taxpayers neglected to check the amended return box when correcting errors from a previously filed return. Missing attachments, such as W-2s or 1099 forms, could prevent the department from validating income, while unsigned returns were automatically returned as incomplete. Taxpayers also failed to mail their returns to the proper department address, which delayed processing by weeks or months. To avoid these problems, individuals should carefully review each return page, confirm that supporting schedules are present, and double-check the filing status before submission. Guidance from the Louisiana Department of Revenue is available at revenue.louisiana.gov, and federal resources to help align state and federal returns can be found at IRS.gov.

Income Tax Return Requirements and Process 

Filing a Louisiana income tax return for the 2013 tax year required taxpayers to provide accurate income, deductions, and credits information. The Louisiana Department of Revenue relied on the details listed on Form IT-540 to determine whether individuals owed additional tax, qualified for refunds, or needed to make future estimated payments. Since millions of residents file returns each year, the department stressed that errors on the form could cause delays, notices, or even penalties.

Reporting Income and Deductions

The first step in completing the return involved reporting the federal adjusted gross income from Form 1040 or 1040A. This figure formed the basis for the Louisiana calculation and determined how much tax a resident must pay. Certain deductions specific to Louisiana applied, including education expenses, medical costs, and disaster-related losses. Filers had to check each page carefully to confirm that all deductions were present before finalizing the return.

Key items to include:

  • Federal AGI: Transfer from the federal return to Line 7 of Form IT-540.

  • Adjustments: Apply disaster loss relief or education expense adjustments.

  • Schedules: Attach Schedule E for adjustments and other required schedules for deductions.

Taxpayers who failed to include these figures correctly often received a notice asking them to provide missing documentation.

Estimated Payments and Balance Due

Louisiana taxpayers were also required to account for estimated payments made during the current year. These payments were often created in January, June, September, and December to help reduce the amount owed at filing. If total payments exceeded the liability, the filer could recover the difference through a refund. If the balance was greater than the estimated payments, taxpayers had to pay tax when submitting the return.

Standard payment methods included:

  • Online payment: Through the Louisiana Taxpayer Access Point (LaTAP) account.

  • Mail payment: By check or money order to the department’s listed address.

  • Payment plan: Contact the department to create a schedule if unable to pay in full.

The department encouraged individuals to visit revenue.louisiana.gov to confirm the most up-to-date payment submission process.

Filing Deadlines and Extensions

The official due date for the 2013 Louisiana income tax return was May 15, 2014. Taxpayers who missed this date were subject to interest and penalties unless they had previously filed for an extension. Filing extensions granted additional time to file paperwork, but not additional time to pay. Payments still had to be present by the original deadline to avoid extra charges.

Important reminders about deadlines:

  • Original due date: May 15, 2014.

  • Extension request: Must be filed before the deadline.

  • Interest accrual: Begins the day after the deadline if full payment was not received.

For clarity, the IRS also provides general rules on extensions that may affect Louisiana taxpayers, which can be found at IRS.gov. State-specific updates are posted directly on the Louisiana Department of Revenue website.

Filing an income tax return requires attention to every line and schedule. From income reporting to deductions, estimated payments, and extensions, each part ensures that taxpayers comply with Louisiana law while claiming the benefits to which they are entitled.

Tax Credits in Louisiana

Child and Dependent Care Credit

The child and dependent care credit was one of the most valuable benefits available to Louisiana taxpayers in the 2013 tax year. This credit helped families recover part of the expenses they paid to care for a qualifying child or dependent while the parent or guardian worked or looked for work. The amount of credit depended on the federal adjusted gross income and expenses listed on the federal return. Taxpayers were required to present documentation showing the provider’s information, the age of the child or dependent, and the total cost of care. Joint filers could claim the credit together, provided both spouses had qualifying income. Individuals not providing proper details often received a notice requesting additional proof.

Education and School Readiness Credits

Louisiana also offered several education-based tax credits in 2013. Families could claim deductions for certain tuition and educational expenses up to set limits. School readiness credits were tied to the star rating of a licensed child care facility, with higher ratings generating larger credits. These programs encouraged parents to explore quality education options while receiving financial relief. To qualify, taxpayers had to ensure they filed the correct schedule with their return. The Department of Revenue made these schedules available for download on its official page at revenue.louisiana.gov. Filers who attached the required forms could expect faster processing, while those who were missing documentation risked delays.

Other Credits Available in 2013

In addition to dependent care and education programs, the state offered credits for donations to approved charities, disaster relief contributions, and carryover credits from prior years. Taxpayers needed to carefully determine whether they were entitled to claim these benefits. Each credit required a separate schedule or form, which had to be submitted with the income tax return. Missing attachments often led to processing delays or denied claims. Individuals were advised to review every credit they might qualify for and ensure that supporting documents were attached to the return before mailing it to the department address. Additional federal resources on credits and deductions can be found at IRS.gov, while Louisiana-specific rules remain on the state’s official site.

How to File and Pay Louisiana State Taxes 

Online Filing and Payments

For the 2013 tax year, the Louisiana Department of Revenue encouraged taxpayers to file their income tax return electronically through Louisiana File Online. This free service allowed individuals to create and submit their forms without needing paper filing. Electronic submission reduced errors, allowed taxpayers to pay tax directly, and ensured faster refund processing. Those making estimated payments during the current year could also apply them to the final balance through the online portal. Taxpayers could access their LaTAP account to manage costs, track balances, and confirm that their information was present and accurate. The system provided secure options to schedule a payment date, recover records, and review previous years’ returns. For details, individuals could visit revenue.louisiana.gov, where official forms and online services were available on every page.

Paper Filing Options

Although electronic filing was recommended, taxpayers still had the option to mail their Louisiana income tax return using Form IT-540. Paper filers had to include all required schedules, social security numbers, dependent details, and signatures. Missing documents often generated a notice from the department, which delayed processing. Returns with payments were mailed to one address, while refund or zero-balance returns were sent to another. Each envelope had to contain the completed form, all pages of supporting schedules, and a check or money order if payment was required. Paper submissions took longer to process, with refunds often issued several months after filing.

Payment Plans

Some taxpayers could not pay their balance in full by the due date and needed to explore payment plan options. The Louisiana Department of Revenue allowed individuals to contact the department and create a structured agreement. These plans required monthly payments until the balance was satisfied. While interest continued to accrue, entering a plan helped taxpayers avoid more serious penalties. Payment plans were available online and by mail, and taxpayers had to present a valid account to set up recurring payments. Joint filers could request a plan together, while individuals were expected to manage their separate accounts. For additional federal guidance on payment arrangements, taxpayers could refer to IRS.gov.

Refund Status and Tracking Your Return 

For taxpayers who filed a 2013 Louisiana income tax return, tracking refund status was essential in confirming that the process was completed successfully. The Louisiana Department of Revenue provided an online tool called “Where’s My Refund,” which allowed individuals to check the progress of their return. To use this tool, taxpayers must enter their social security number, select their filing status, and enter the expected refund amount. Electronic filers could generally expect their refund within 21 days if they used direct deposit, while paper returns often took several weeks or months to process.

The department reminded taxpayers that refund processing times varied depending on when the return was submitted and whether all supporting documents were present. Returns filed in January or early in the filing season were often processed more quickly than those filed in June, July, or later months. Missing pages, incorrect information, or a notice sent by the department could extend processing significantly. Taxpayers who claimed multiple tax credits or filed an amended return were more likely to face delays as the department verified eligibility. Millions of individuals filed Louisiana returns for the 2013 tax year, and the department used additional review measures to ensure accuracy.

When questions arose about refund status, taxpayers were encouraged to explore multiple resources. They could visit revenue.louisiana.gov to use the online tracking system or review updates on the department’s official page. Contact options included email, phone, and written correspondence to the correct address. Federal resources on refund processes were also available at IRS.gov for those who needed further guidance. By checking their accounts regularly and responding to any notices issued by the department, taxpayers could recover the funds they were entitled to within a reasonable time frame.

How to File an Amended Return in Louisiana 

  • When to File an Amended Return
    Taxpayers must file an amended return if they discover errors or omissions on their 2013 Louisiana income tax return. Common reasons included reporting the wrong income, failing to claim deductions or tax credits, or leaving out dependent information. An amended return was also required if a spouse’s income or filing status was incorrectly reported. Filing promptly allowed taxpayers to recover refunds they were entitled to or to reduce penalties and interest that might otherwise accumulate.

  • How to Complete the Amended Return
    The process required taxpayers to use Form IT-540 again, but this time, they had to clearly mark the “Amended Return” box on the first page. All corrected information, not just the changed items, had to be fully presented. The updated return had to include supporting schedules, such as adjustments, credits, or deductions. Taxpayers could mail the amended return to the Louisiana Department of Revenue at the correct address for their filing type. Those who paid electronically could also confirm adjustments by logging into their LaTAP account.

  • Differences Between Original and Amended Returns
    The processing time for an amended return was usually longer than that of an original income tax return. While electronic returns could be processed quickly, amended returns often required additional review by the department, particularly when multiple credits or deductions were involved. Taxpayers filing in October, November, or December could expect additional delays due to year-end workloads. The department sometimes issued a notice requesting further documentation before processing was complete. For more detailed information, taxpayers could visit revenue.louisiana.gov or review the amendment rules on IRS.gov.

Final Filing Checklist for Taxpayers 

Required Information

Before sending the Louisiana income tax return for the 2013 tax year, taxpayers needed to confirm that every line of Form IT-540 was complete. This included verifying that each social security number was accurate, the spouse’s details were correctly listed for joint filers, and the current address was present. Any missing or incorrect information could create processing delays or lead to a notice from the Louisiana Department of Revenue. Taxpayers also had to ensure that the filing status they selected matched the federal return.

Attachments

Supporting documents were an essential part of the filing process. Taxpayers were required to include all W-2s, 1099s, and schedules that supported deductions or tax credits. For example, those claiming the dependent care or education-related credits had to attach proof of expenses and provider information. Every page of the return and its attachments had to be mailed together to the correct department address. Missing attachments were among the most common reasons for refund delays and notices.

Recordkeeping

After submitting the return, taxpayers were advised to create and keep copies of every form page, schedule, and supporting document. Records should be stored securely for at least four years from the filing date. Maintaining these records allowed taxpayers to recover information quickly if a notice was received or an amended return had to be filed later. Accurate records also helped individuals qualify for future deductions or credits by showing proof of past filings. For official filing guidelines, taxpayers could visit revenue.louisiana.gov or consult additional resources provided on IRS.gov.

Important Dates and Deadlines to Remember 

Filing Window

The official filing window for the 2013 Louisiana income tax ended on May 15, 2014. Any taxpayer who did not file by this date risked paying interest and penalties. Extensions were available, but they only granted additional time to file paperwork, not to pay tax owed. Payments still had to be present by the original deadline to avoid extra charges. Taxpayers who made estimated payments during the current year in January, June, September, and December were expected to apply those amounts toward their final balance. Filing on time was the most effective way to prevent a notice and to recover refunds more quickly.

Month-by-Month Highlights

Several months carried special importance for Louisiana taxpayers during this process. January marked the start of preparation when millions of individuals began gathering their W-2s and other income records. June and July often required mid-year estimated payments, while October and November were busy for taxpayers who needed to file an amended return or correct missing information. December was the last opportunity to make payments or adjustments before the year ended. Each of these months influenced the process by setting deadlines that helped determine whether taxpayers could qualify for credits, claim deductions, or avoid interest charges. Official reminders were issued on the Louisiana Department of Revenue’s page at revenue.louisiana.gov, and federal guidance about deadlines was also available at IRS.gov.

Exploring Common Questions and Situations 

Many Louisiana taxpayers faced common challenges when completing their 2013 income tax return. One frequent issue involved late filing, often when individuals overlooked the May 15 deadline or failed to make estimated payments during the current year. Taxpayers who filed after the due date could expect to pay additional interest, receive a notice, or lose out on certain credits they might otherwise qualify for. Filing as soon as possible, even after the deadline, helped reduce penalties and increased the chance of recovering refunds.

Another situation that created confusion was the difference between federal and state requirements. While the IRS required certain deductions and schedules, the Louisiana Department of Revenue had rules for specific education expenses, child-related credits, and dependent care credits. Taxpayers needed to explore the Louisiana instructions carefully, making sure every page of Form IT-540 and supporting schedules was complete. Joint filers also had to ensure that each spouse’s information was accurate and consistent with federal documents. Errors often led to processing delays, additional notices, or requests for proof of eligibility.

Finally, many individuals asked what to do if they realized they had made a mistake after filing. The correct approach was to submit an amended return with corrected information and all required schedules. This was especially important for taxpayers who forgot to claim deductions, miscalculated income, or overlooked dependent information. Submitting an amended return allowed them to recover refunds and prevent problems in future years. Question-payers were encouraged to contact the Louisiana Department of Revenue directly or visit revenue.louisiana.gov for guidance. Federal assistance on filing requirements could also be reviewed at IRS.gov.

Frequently Asked Questions 

What was the filing date for the 2013 Louisiana income tax return?

The official filing date for the 2013 Louisiana income tax return was May 15, 2014. Taxpayers who filed after this deadline were required to pay interest and penalties unless they had submitted a valid extension request. Filing on time allowed individuals to recover refunds more quickly, reduce the chance of receiving a notice, and avoid unnecessary charges. The Department of Revenue treated the due date as an essential requirement.

Can I still file a late return for the 2013 tax year?

Yes, taxpayers may still file a late return for the 2013 tax year, but penalties and interest could apply if tax was owed. Those expecting refunds could still qualify to recover them, but they should not wait too long. In most cases, Louisiana allows up to three years from the original date to file a valid refund claim.

How do I check the status of my refund?

Taxpayers can check the refund status for the 2013 Louisiana return using the Department of Revenue’s online service. This required a social security number, filing status, and refund amount. Electronic filers could expect refunds in about 21 days, while paper filers waited longer. Refund delays often happened if pages were missing, schedules were incomplete, or the department issued a notice asking for additional information.

What are the steps for filing an amended return?

To file an amended return for the 2013 Louisiana tax year, taxpayers must complete a new Form IT-540 and mark the amended return box at the top of the page. All corrections, not just the updated items, had to be fully included. Supporting schedules for deductions or tax credits had to be attached. Amended returns generally required more review, which meant longer processing times.

Which tax credits were available in 2013?

The 2013 Louisiana income tax return included several tax credits designed to provide relief for eligible taxpayers. These credits covered the child and dependent care credit, school readiness credits, and various education-related benefits. Additional credits also applied to charitable donations and disaster relief contributions. To qualify, taxpayers had to provide documentation such as receipts, provider details, and proof of eligibility. Missing or incomplete information often resulted in a notice and delayed refund processing.

Do joint filers need special forms?

Joint filers did not need a different form. They used the same IT-540 as single taxpayers but had to include both spouses’ income, deductions, and dependent information. Careful reporting was necessary, since mistakes with a spouse’s social security number or filing status often triggered notices. Both filers were responsible for ensuring the accuracy of all schedules and pages before mailing the return to the department.

What if I missed making estimated payments during the current year?

Missing estimated payments during the current year could increase the amount a taxpayer owes at filing. If the balance due were large, interest and penalties would apply. However, taxpayers could still resolve this by paying at the time of filing or by arranging a payment plan with the Department of Revenue. Quick action helped reduce notices, protect credits, and ensure compliance for the next tax year.
