Filing taxes late in Mississippi has never been cheap. For the 2017 tax year, any resident with income above $8,300 (plus $1,500 for each dependent) was required to file. Missing the filing deadline of April 15, 2018, could cost you 5 percent of unpaid monthly taxes, up to a maximum of 25 percent, plus additional penalties and interest. A person expecting a refund could also face a painfully slow process if the paperwork were incomplete.

The Mississippi Department of Revenue manages every tax return filed in the state and enforces rules on income tax, penalties, and refunds. It oversees state returns not only for individuals but also for businesses and those with self-employment income. By monitoring deadlines and payment records, the department ensures that all taxpayers meet state law while maintaining consistency with federal requirements from the IRS. Filing is about compliance with the law, protecting your money, and avoiding unnecessary costs.

This article will walk you through how to file your 2017 Mississippi tax return. We will explain which forms you need, how to prepare your records, and the options to submit your return by mail, e-file, or even in person. You will also learn the advantages of direct deposit for faster refunds, common mistakes to avoid, and how to work with a tax preparer if needed. By the end, you will understand the process and why early and accurate filing is the smartest choice for your finances.

Who Needs to File a Mississippi Tax Return?

The first step in knowing how to file your Mississippi tax return for 2017 is determining whether you must file. Mississippi law set clear income thresholds and filing rules for the 2017 tax year, and understanding them is critical to avoid penalties or missing out on a refund.

Full-Year Residents

You had to file a Mississippi tax return if you were a resident for the whole year and met one of these conditions:

  • Your employer withheld Mississippi income tax from your wages.

  • Your gross income exceeded $8,300 if you were single, plus $1,500 for each dependent.

  • Married couples had to file if their combined income was over $16,600 plus $1,500 per dependent.

  • Minors were required to file if their income exceeded their exemption plus standard deduction.

Non-Residents and Part-Year Residents

If you lived outside Mississippi but earned income in the state, or if you moved into or out of Mississippi during 2017, you were required to submit a return. Non-residents typically filed Form 80-205 to report only Mississippi-source income, while part-year residents reported revenue for the portion of the year they lived in the state.

Self-Employment and Small Businesses

Individuals with self-employment or business income also had to file. This included sole proprietors, contract workers, and small business owners who generated taxable income in Mississippi. Even if your taxes were not withheld from a paycheck, you were responsible for paying what you owed.

Special Filing Situations

Married couples had choices: joint, separate, or combined filing. Selecting the right filing status could lower overall tax liability. Taxpayers eligible for additional exemptions, such as those aged 65 or being blind, still need to file if they exceed the income thresholds.

Why This Step Matters

Failing to determine your filing requirement could be costly. Mississippi imposed a penalty of 5 percent per month for late filing (up to 25 percent), plus 0.5 percent per month for late payment. A person who ignores the rules could incur hundreds in fees, while those due a refund would see their money delayed for months. Reviewing your situation ensures you qualify correctly and comply with state law.

Key Deadlines and Extensions in 2017 Updates

For the 2017 tax year, the Mississippi filing deadline was April 15, 2018. This was the official due date for filing your return and paying any balance owed. Missing this date could quickly lead to penalties and interest that eat into your refund or increase what you already owe.

Standard Deadlines

  • Filing deadline: April 15, 2018

  • Payment deadline: April 15, 2018 (applies even if you request an extension)

  • Extension deadline: Matches the federal extension period granted by the IRS

It is important to note that an extension applies only to submitting your return, not to paying taxes. Any unpaid balance after the due date begins accumulating costs immediately.

Penalties and Interest

Failing to meet the deadline comes with serious consequences:

  • Late filing penalty: 5 percent per month of the unpaid balance, up to 25 percent.

  • Late payment penalty: 0.5 percent per month of the unpaid balance.

  • Interest: 0.7 percent per month on any outstanding tax.

A taxpayer who waits several months could easily incur hundreds of dollars in extra charges.

Deciding Your Next Step

If you cannot pay in full by the deadline, the best option is to decide on a payment plan with the Mississippi Department of Revenue. Setting up a structured process for payment will minimize long-term penalties and protect your finances. The sooner you take action, the less you will owe in the long run.

Essential Forms and Documents

Before preparing and submitting your 2017 Mississippi return, you will need the correct forms and supporting records. Using the wrong documents or failing to attach schedules is one of the most common reasons the Department of Revenue delays refunds. Taking time to gather everything first will save frustration later.

Main Forms for 2017

  • Form 80-105: For full-year Mississippi residents filing an income tax return.

  • Form 80-205: For non-residents and part-year residents reporting Mississippi-source income.

These two forms are the foundation of all state returns. Which one you use depends on your residency status during the 2017 tax year.

Supporting Forms and Schedules

  • Form 80-107: Income/Withholding Tax Schedule (required for every filer).
  • Form 80-108: Contains multiple schedules:
    • Schedule A: Itemized deductions
    • Schedule B: Interest and dividend income
    • Schedule N: Other income and supplemental income
  • Form 80-106: Payment voucher, used if you owe taxes and will pay by check or money order.
  • Additional forms may apply if you need to claim credits or adjustments.

Records You Should Gather

  • Wages: W-2 forms from each employer.
  • Paycheck stubs if withholding is not fully reported on W-2s.
  • 1099 forms: for contract income, dividends, and retirement distributions.
  • A copy of your federal tax return, which Mississippi requires.
  • Proof of deductible expenses: mortgage interest, property tax bills, charitable donations, and medical expenses.

Why It Matters

Missing even one form can delay your refund by weeks. For example, the state cannot verify your payment history if you fail to attach a W-2 showing Mississippi withholding. Before filing, take time to review your paperwork carefully. Organizing these documents in advance will make the filing process smoother and may reduce costs if you work with a tax preparer.

Step-by-Step Guide to Filing

Filing your 2017 Mississippi tax return may feel complicated, but breaking it down into clear steps makes it manageable. This process will help you avoid mistakes, reduce penalties, and secure your refund faster.

Step 1: Gather and Prepare Your Documents

Start by collecting all required records: W-2s from each employer, 1099 forms, and your federal return. Do not forget receipts for medical expenses, mortgage interest, or charitable donations. These documents are essential if you decide to itemize. Having everything ready before you begin will make the process smoother.

Step 2: Determine Your Filing Status

Your filing status directly impacts your exemption amount and standard deduction. The options include:

  • Single

  • Married Filing Jointly

  • Married Filing Separately

  • Combined return (special to Mississippi)

  • Head of Family

  • Qualifying Widow(er)

A married taxpayer filing with a spouse may save money by filing a combined return, while someone with a dependent child may qualify as head of family. Carefully decide which option fits your situation.

Step 3: Calculate Gross Income and Exemptions

Add up your gross income, including wages, self-employment earnings, investment returns, and retirement distributions. Then subtract personal exemptions and those for dependents. A person aged 65 or older, or blind, may claim an additional exemption. Forgetting these reduces your refund unnecessarily.

Step 4: Report Income

All income sources must be reported on Form 80-107 and transferred to your main form (80-105 or 80-205). This includes:

  • Wages and salaries from each paycheck

  • Self-employment or business profits

  • Dividends, interest, and capital gains

  • Rental or farm income

  • Retirement pensions or annuities

Failing to report even small amounts could trigger a notice from the Department of Revenue and delay your refund.

Step 5: Apply Deductions and Credits

Next, decide whether to take the standard deduction or itemize.

  • Standard deduction: Based on your filing status.

  • Itemized deductions: Medical expenses, property taxes, mortgage interest, and donations.

You may also be eligible for credits for taxes paid to another state. Always review your return to ensure credits are included.

Step 6: Calculate Taxes and Compare Payments

Subtract exemptions and deductions from your adjusted gross income to find taxable income. Use the state tax tables to determine how much you owe. Then compare that amount to taxes already withheld by your employer or estimated payments you made during the year. This will determine if you still owe money or are due a refund.

Step 7: Choose How to File

Mississippi offers three ways to submit your return:

  • E-file through the Taxpayer Access Point (fastest option).

  • Mail your forms to the correct address.

  • File in person at a district office.

E-filing is generally the best choice for speed and accuracy. Filing by mail or in person may involve longer wait times and higher error risk.

Step 8: Pay Any Balance Owed

If you still owe taxes after calculating your return, you must pay by the due date to avoid penalties. Options include bank transfer, check, or credit card. If you cannot pay in full, request a payment plan to spread the balance over time. This helps you avoid incurring higher costs from penalties and interest.

Step 9: Double-Check Before Submission

Before you submit, review your return carefully. Confirm that Social Security numbers match, exemptions are listed, dependents are included, and all required schedules are attached. If filing jointly, both the taxpayer and the spouse must sign. Missing signatures are a common cause of refund delays.

Step 10: Keep Copies for Your Records

Always keep copies of your filed return, supporting documents, and payment history for at least three years. These records protect you if questions arise later, making the next tax year easier to prepare.

Filing Options and Payment Methods

Once you have completed your Mississippi tax return for 2017, the next step is deciding how to submit it and how to handle any balance owed. The Mississippi Department of Revenue offers flexible filing methods and several ways to pay. Choosing the right approach can save both time and money.

Filing Options

  • E-file: The fastest and most accurate method is filing electronically through the Taxpayer Access Point. E-filed returns are processed quickly, and refunds can be issued in as little as 30 days.

  • Mail: If you prefer paper filing, you can mail your return to the Department of Revenue. Be sure to use the correct address, which differs depending on whether you expect a refund or owe a balance.

  • In person: Returns may also be filed at local district offices. While this option allows you to ask questions directly, it often involves longer wait times.

Payment Options

If you owe taxes for the 2017 tax year, Mississippi provides several payment methods:

  • Electronic transfer: Pay directly from a bank account using your routing and account numbers.

  • Credit or debit card: Convenient, but may include additional fees.

  • Check or money order: Send with Form 80-106 if you pay by mail.

  • In-person payments: These are accepted at district offices, allowing you to pay while filing.

Payment Plans

If you cannot pay the full balance by the due date, you may request a payment plan. This allows you to spread the amount over time, reducing the risk of larger penalties. Interest will still apply, but setting up a plan prevents further collection costs and keeps your account in good standing.

Cost Considerations

Payment methods vary in cost. Bank transfers are generally free, while card payments include processing fees. Filing electronically reduces errors, which may save you money by avoiding penalties or reprocessing charges. By choosing the filing and payment method that best fits your situation, you can minimize expenses and avoid unnecessary delays in processing your return.

Refunds and Tracking Your Return

After you file your Mississippi tax return for 2017, the most common question is how long it will take to receive your refund. The answer depends on the method you used to submit your return and how you chose to receive your money.

Refund Timelines

  • E-file with direct deposit: Refunds are typically issued within 30 days if there are no errors.

  • Paper returns by mail: Refunds can take 8 weeks or more, especially if missing forms or corrections are required.

  • Amended returns: These often require extra review and may be delayed further.

Choosing Direct Deposit

Direct deposit is the fastest and safest way to get your refund. It avoids postal delays and lets you receive funds directly into your bank account. To set it up, you must provide your routing and account numbers on the return.

Tracking Refunds

Taxpayers can track their refund status through the Mississippi Department of Revenue’s tax account system. By entering your Social Security Number and the expected refund amount, you can check whether your return is still being processed, approved, or paid out. This service offers real-time access to your refund details.

Interest on Delays

Depending on the circumstances, interest may apply if the Department of Revenue takes unusually long to issue your refund. This is rare, but it highlights why filing electronically and requesting direct deposit is the best choice. Direct deposit speeds up the process and minimizes the risk of lost checks or long waits. It is the option most taxpayers should consider first.

Common Mistakes to Avoid

Even well-intentioned taxpayers can make errors when filing a Mississippi tax return. These mistakes generally lead to delayed refunds, notices from the Department of Revenue, or unexpected penalties. Knowing the common pitfalls will help you avoid extra costs.

Filing Status Errors

One of the most frequent issues is choosing the wrong filing status. Married couples sometimes forget to compare joint, separate, and combined returns to see which option reduces their tax liability the most. A quick review before you file can save money.

Missing or Incorrect Information

Taxpayers often forget to attach W-2s or 1099s or fail to sign their return. If you are married, note that both spouses must sign a joint return. Returns with missing signatures are automatically sent back, which delays processing.

Dependent and Exemption Errors

Incorrectly claiming a dependent or forgetting additional exemptions for age or blindness is another common mistake. These errors may result in overpaying taxes or having to amend your return later.

Misreporting Income or Payment History

Leaving out a small 1099 or failing to match reported wages with employer records can trigger a state review. Always double-check your reported payment history against pay stubs and prior forms.

Skipping Professional Help

Some situations are complex enough that working with a tax preparer is worth the cost. A preparer can ensure forms are complete and accurate, especially if you run a business, have had significant life changes, or are unsure about credits. While not free, this investment may save more than it costs by preventing penalties.

Why Filing Early Saves Money and Stress

Waiting until the last minute to file your 2017 Mississippi tax return often creates unnecessary pressure. Filing early provides several advantages that can save you both money and time.

Faster Refunds

The earlier you submit your return, the sooner it can be processed. Taxpayers filing early and selecting direct deposit generally receive their refund within 30 days. Those who wait until the April deadline often face longer processing times and may not receive their money for weeks.

Avoiding Penalties

If you owe taxes, filing early gives you more time to set up a payment plan or arrange payment options. This reduces the chance of missing the due date and incurring costly penalties. Filing early also ensures you have time to review your return and make corrections before deadlines pass.

Peace of Mind

Rushing close to the deadline often leads to avoidable errors. Filing early gives you breathing room to consult with a tax preparer if needed, without paying rush fees or risking mistakes. In some cases, the Department of Revenue also provides free electronic filing options for qualifying taxpayers, making it easier to submit accurately without extra cost. Filing early relieves stress and protects your finances. Whether you are expecting a refund or planning to pay, the benefits of filing ahead of the deadline are clear.

Frequently Asked Questions (FAQs)

Do I need a tax preparer to file my 2017 Mississippi income tax return?

Not every taxpayer needs a tax preparer, but hiring one can be helpful if your situation is complex. A preparer ensures forms are accurate, exemptions are applied correctly, and deductions are not overlooked. While there may be a cost, using a professional may save money by preventing penalties or delays. You can generally prepare and submit simple returns on your own.

What happens if I miss the filing due date?

Missing the due date of April 15, 2018, leads to penalties and interest. The late filing penalty is 5 percent per month of unpaid taxes, up to 25 percent, while the late payment penalty adds 0.5 percent per month. Interest also accrues at 0.7 percent per month. Even if you expect a refund, delaying your return can significantly postpone when you receive your money back.

Can I file in person instead of online?

Yes, Mississippi allows taxpayers to file in person at district offices if they prefer not to submit electronically. This option may be convenient if you want to ask questions directly or pay by check while filing. However, processing in-person returns typically takes longer than e-file submissions. Taxpayers seeking faster refunds and fewer errors should generally consider electronic filing through the state’s Taxpayer Access Point.

Is it better to e-file or mail my return?

Most taxpayers strongly recommend using e-files. Electronic filing reduces errors, speeds up refunds, and confirms that your return was received. Paper returns sent by mail often take 8 weeks or longer, compared to about 30 days for e-filed returns with direct deposit. Choosing electronic filing also makes contacting and tracking your refund easier through the Department of Revenue’s tax account system.

How are penalties calculated as a percentage of taxes owed?

Mississippi applies penalties as a percentage of your unpaid balance. The late filing penalty is 5 percent per month, capped at 25 percent. The late payment penalty is 0.5 percent per month. In addition, an interest of 0.7 percent per month is added until the balance is paid in full. These charges accumulate quickly, so taxpayers should file and pay on time or request a payment plan to reduce costs.
