In 2014, nearly 79 percent of Missouri taxpayers filed their state returns electronically. Those who opted for paper filing often faced a painfully slow process, with refunds delayed for eight weeks or longer. That difference in speed highlights how important it is to choose the correct filing method and carefully prepare your return.

Filing your Missouri state tax return for 2014 may feel overwhelming, especially if you are worried about making mistakes or missing deadlines. A simple math error can delay your refund for weeks. Forgetting to sign your return or attach a W-2 can result in a rejected filing. Missing the filing deadline could cost you hundreds of dollars in penalties and interest. These are easily avoidable errors if you understand the process step by step.

This guide will walk you through how to file your Missouri tax return for 2014, from determining whether you need to file to tracking your refund once it is submitted. We will cover filing requirements, the different forms available, how to choose between electronic and paper filing, and the penalties you can face if you do not file correctly or on time. With clear instructions and practical comparisons, you can file confidently, avoid costly mistakes, and ensure you receive the refund you are owed as quickly as possible.

Who Must File a Missouri State Tax Return

Not every Missouri resident or worker must file a state tax return. However, many overlook that even if their income is below the threshold, filing could still result in a refund of money already withheld from their paycheck. Understanding who needs to file helps you decide whether you are legally required to submit a return or whether it may be to your financial advantage to do so anyway.

Filing Requirements for Missouri Residents

  • You must file a Missouri state return if you were required to file a federal tax return and earned enough Missouri income to meet the threshold.

  • For the 2014 tax year, residents with more than $1,200 in Missouri adjusted gross income were required to file.

  • Even if your income is below that amount, you may want to file if your employer withheld Missouri income taxes; filing allows you to claim a refund.

Filing Requirements for Nonresidents

  • Nonresidents must file a claim if they earned $600 or more in Missouri income in 2014.

  • If you worked temporarily in Missouri while living in another state, your employer may have withheld Missouri taxes from your paycheck. In this case, you may need to file to get those funds back.

Special Rules for Part-Year Residents and Military Personnel

  • Part-year residents must file if they earned more than $1,200 while living in Missouri.

  • Military personnel often face different filing rules depending on their residency status and duty location. Active duty service members should check the Missouri Department of Revenue instructions for special exemptions that may apply.

Why Filing Matters Even If You Are Not Required

Many taxpayers assume that they can ignore filing entirely if they fall below the threshold. The problem is that this often means leaving money on the table. If your employer withheld even a small amount of Missouri tax, filing allows you to claim those funds. Failing to file could mean missing out on a refund that belongs to you.

Missouri Tax Forms Explained

One of the first steps in figuring out how to file your Missouri tax return for 2014 is choosing the proper form. Missouri offers several versions of its state tax return, and picking the wrong one can lead to delays, rejected filings, or extra paperwork later. Each form is designed for a different type of taxpayer, so deciding which fits your situation is essential before you begin.

Form MO-1040 (Long Form)

  • This is the universal form, meaning anyone can use it regardless of income or filing complexity.

  • It is required if you have adjustments to income, credits, or more complicated tax situations, such as multiple employers or income from other states.

  • It is also the only form that can be used to file an amended Missouri tax return.

Form MO-1040A (Short Form)

  • Best for taxpayers with simple situations.

  • It can be used if you are single or married and filing jointly, and your income comes only from wages, salaries, tips, or taxable benefits.

  • You may claim either the standard deduction or itemized deductions.

  • It does not allow for most credits or modifications, so if you qualify for special deductions, you must use the long form instead.

Form MO-1040P (Property Tax Credit Form)

  • Designed for individuals eligible for a property tax credit or certain pension exemptions.

  • Often used by seniors and disabled taxpayers who qualify for Missouri’s property tax credit.

  • Simple to complete if your only goal is to claim this credit without filing the more complex forms.

Deciding Which Form to File

To decide which form is best, consider your income sources and whether you need to claim any credits. For example:

  • A single filer with one W-2 and no other income usually qualifies for the MO-1040A.

  • A married couple with income from multiple employers in different states will need the MO-1040.

  • A retiree claiming only the property tax credit may only need the MO-1040P.

How to Get the Right Form

The Missouri Department of Revenue provides free access to all forms on its website. You can print paper versions, request them by mail, or use fill-in PDF versions that automatically calculate amounts. Using the proper form makes filing easier and helps ensure your tax return is processed without unnecessary delays.

Step-by-Step Filing Process

Filing your Missouri state tax return for 2014 requires careful attention to detail. The process is straightforward if you follow each step in order and avoid common mistakes. This section will walk you through the process, from entering your personal information to calculating your final refund or balance due.

Personal Information and Filing Status

The first section of your Missouri tax return focuses on your details.

  • Enter your full legal name, Social Security number, and current address exactly as they appear on your federal tax return. Any mismatch could cause delays.

  • If you are filing jointly, your spouse’s name and Social Security number must also be included. Both spouses must sign the return for it to be valid.

  • Your filing status should match the status you used on your federal income tax return. The only exceptions are if you are a dependent on another person’s return or if you qualify for a special married filing separately status with no income for your spouse.

Standard error: Forgetting to match your filing status to your federal return can delay processing.

Income Reporting

After completing your details, you must report your income.

  • Begin with your federal adjusted gross income. This is copied directly from your federal tax return (Form 1040 line 37, Form 1040A line 21, or Form 1040EZ line 4).

  • Subtract any state tax refunds you reported as income on your federal return.

  • Include income from wages, retirement distributions, interest, dividends, and other Missouri sources. Remember that employers should provide you with W-2s and 1099s showing taxes withheld.

Tip: Always attach copies of your W-2 and 1099 forms. Missing attachments are one of the most common reasons state returns are rejected.

Deductions and Exemptions

Next, you will reduce your taxable income by applying deductions and exemptions.

  • Federal tax deduction: Missouri allows you to deduct federal income tax paid, with a maximum of $5,000 for single filers or $10,000 for married couples filing jointly. This is not the same as income taxes withheld; it is the actual tax owed on your federal return.

  • Standard or itemized deductions: Use the standard deduction amount listed for your filing status, or itemize if it reduces your tax liability further. If you itemized on your federal return, you should also itemize on your Missouri return.

  • Dependents: Each dependent you claim reduces your taxable income by $1,200. Dependents must be the same individuals listed on your federal return.

  • Long-term care insurance deduction: If you paid premiums for qualifying policies, you may claim this deduction using the state-provided worksheet.

Standard error: Taxpayers often confuse withholding with tax owed. Always use the tax amount from your federal return when calculating the Missouri deduction.

Calculating Taxes and Credits

Once deductions and exemptions are applied, you can determine your Missouri tax liability.

  • If your taxable income is under $9,000, use the tax chart provided with the form to calculate your tax. If it is higher, you must use the state’s worksheet.

  • Subtract credits and withholdings. Common credits include property tax credit, child deduction, and pension exemption.

  • Enter Missouri income tax withholding from your W-2s and 1099s. Only Missouri withholding counts; federal or other states’ withholding does not apply here.

  • Include any estimated tax payments you made during 2014 and any credit from your 2013 return.

The final result will show whether you are due a refund or owe money to the state. Filing accurately helps ensure you receive any refund quickly and avoids unnecessary interest or penalties if you owe.

How to File: Electronic vs Paper

Once you have completed your Missouri tax return 2014, the next step is deciding how to submit it. Taxpayers can choose between electronic filing and paper filing. Each method has its advantages and drawbacks, and your choice can affect how quickly your return is processed and when you receive your refund.

Electronic Filing (E-file)

Electronic filing has become the preferred choice for most taxpayers. In 2014 nearly eight out of ten Missouri state returns were filed electronically.

  • Faster processing: Refunds from e-filed returns are usually issued in about 30 days, while paper returns can take 8 weeks or more.

  • Fewer errors: Filing software checks calculations automatically, helping taxpayers avoid costly mistakes.

  • Direct deposit option: Refunds can be sent straight to your bank account, avoiding the wait for a paper check.

  • Confirmation: Once submitted, you receive an immediate confirmation that your return was received.

  • Free filing options: Some taxpayers are eligible for Free File programs if their income falls below certain thresholds.

Paper Filing

Paper filing remains an option, but it comes with clear disadvantages compared to e-filing.

  • Slower processing: Paper returns are processed manually, which takes significantly longer. Refunds may take 8 weeks or more.

  • Higher error risk: Math mistakes, missing signatures, or misplaced documents are common.

  • Mailing costs and delays: Returns must be mailed to the correct Missouri Department of Revenue address. Using the wrong address can add weeks of delay.

  • No instant confirmation: You will not know whether your return has been received until it is processed.

Filing Addresses for Paper Returns

If you choose to file by paper, you must send your return to the correct address:

  • Refund returns: Department of Revenue, P.O. Box 500, Jefferson City, MO 65106-0500.

  • Balance due returns: Department of Revenue, P.O. Box 329, Jefferson City, MO 65107-0329.

  • Special 2-D barcode returns have different addresses listed in the instructions.

Deciding Which Method to Use

Most taxpayers benefit from e-filing. It saves time, reduces stress, and gets refunds deposited much faster. Paper filing may make sense only if you are more comfortable submitting a physical return or cannot access electronic filing services. However, even in those cases, the delays and risks of paper filing often outweigh the benefits.

Filing Deadlines, Extensions, and Penalties

One of the most important parts of knowing how to file your Missouri tax return 2014 is keeping track of the filing deadline. For the 2014 tax year, returns were due by April 15, 2015. The deadline automatically moved to the next business day if the date fell on a weekend or federal holiday. Filing after this date meant you risked penalties, interest, and the loss of money that could have been refunded.

Filing Deadline

  • Regular deadline: April 15, 2015.

  • Extension deadline: October 15, 2015. An extension gives you more time to file, but does not give you more time to pay. Any taxes you owe must still be submitted by the April filing date to avoid charges.

  • Why it matters: Missing the filing deadline can cost you hundreds of dollars in penalties, and in some cases, if too much time passes, it may prevent you from claiming a refund.

Extension Options

Taxpayers who could not file by April 15 had the option of submitting Form MO-60 or attaching a copy of their approved federal extension. While this gave an extra six months to file the personal income tax return, it did not stop interest from building on unpaid balances. Filing an extension can help you avoid the late-filing penalty, but you will still need to estimate what you owe and pay that amount by the original due date.

Penalties and Interest

Missouri applies penalties and interest to encourage on-time filing.

  • Late filing penalty: 5 percent of the unpaid tax for every month the return is late, up to a maximum of 25 percent.
  • Late payment penalty: 5 percent in addition to the taxes owed if you fail to pay by the April 15 deadline, even if you filed the return on time.
  • Interest charges: Interest accumulates immediately after the due date and continues until the balance is paid.

Failing to file or pay on time is more than a minor inconvenience. Penalties can quickly add up to a high percentage of the balance due. A taxpayer who owed $2,000 and failed to file for five months could face $500 in penalties, plus interest. Filing on time, even if you cannot pay the full amount, helps you reduce or eliminate penalties while you arrange payment options.

Payment Options if You Owe

Filing your Missouri state tax return for 2014 does not always result in a refund. If you owe money to the state, you must decide how to pay by the filing deadline to avoid penalties and interest. Fortunately, Missouri offers several payment options that make the process more manageable.

Paying by Check or Money Order

  • Make the check or money order payable to the Missouri Department of Revenue.

  • Payments must be in U.S. funds only.

  • Do not postdate your check; the state will not accept it.

  • If you mail your payment, it must be postmarked by April 15, 2015.

Paying Electronically

  • Electronic Bank Draft (E-Check): You can pay directly from your bank account online or by calling the state’s payment hotline. This service is convenient, but a small convenience fee may apply.

  • Credit Card Payment: The state accepts Visa, MasterCard, Discover, and American Express. Payments can be made online or by phone. Credit card processors charge service fees that vary by amount; for example, about $2.15 for a $100 payment or 2.15 percent of the payment if the amount is higher.

  • IRS Link: While state and federal taxes are separate, many taxpayers handle both simultaneously. Paying the state electronically is as secure as paying the IRS.

Payment Plans and Extensions

If you cannot pay the full amount you owe, do not skip filing your return. Filing prevents the late-filing penalty and limits your charges to late-payment penalties and interest. Missouri allows taxpayers to request a payment plan, which spreads the balance over several months. Interest and penalties will still apply, but you will avoid collection actions that can happen if you ignore the debt.

Why It Is Important to Pay On Time

Failing to pay by the deadline can cost far more than taxes. For example, a taxpayer who owed $1,500 but waited several months to arrange payment could face hundreds of dollars in extra charges. By filing on time and paying promptly, you protect your funds, reduce stress, and keep your account in good standing with the state.

Tracking Your Refund

After you file your Missouri state tax return for 2014, you will want to know when your refund will arrive. Refunds are not issued instantly; they go through a review and verification process before funds are released. How quickly you receive your money depends on the filing method, the accuracy of your return, and whether you requested direct deposit.

Online Refund Tracking

The Missouri Department of Revenue offers an online tool available 24/7 to help you track your refund.

  • On your return, you must enter your first Social Security number, your filing status, and the refund amount in whole dollars.

  • This system allows you to determine the current stage of your refund process.

  • Refunds are generally faster when you e-file, often within 30 days, compared to 8 weeks or longer for paper returns.

Phone Inquiry Option

If you prefer, you can check the status of your refund by calling the automated phone line at (573) 526-8299. Like the online tool, you will need your Social Security number, filing status, and refund amount to get an answer. This service is free and available at all times.

Processing Timelines

  • Electronic filing with direct deposit: Refunds usually arrive within 30 days.

  • Electronic filing with paper check: Allow slightly longer due to mail delivery times.

  • Paper filing: Refunds can take 8 weeks or more, especially if there are math errors or missing documents.

Why Refund Tracking Matters

Taxpayers who track their refunds can quickly spot problems such as rejected submissions or delayed processing. If their refund is late, checking the status helps them determine whether they need to submit additional documents or contact the Department of Revenue. Being proactive ensures they receive their money as quickly as possible.

Common Filing Mistakes to Avoid

Even if you understand how to file your Missouri tax return for 2014, minor errors can cause costly delays. Some mistakes may reduce your refund, while others can lead to penalties or rejection of your return. By noting the most common filing errors in advance, you can avoid problems and keep the process smooth.

Using the Wrong Numbers

Many taxpayers confuse income taxes paid with the tax owed on their federal return. Missouri allows a deduction for federal income tax, but only the actual tax liability counts. Entering the amount withheld from your paycheck instead of the amount owed is one of the most common mistakes.

Forgetting to Attach Documents

Always attach W-2s, 1099s, and other required forms. Missing documents are a leading cause of refund delays. Attach the necessary worksheets or schedules if you are claiming deductions or credits.

Incorrect Filing Status

Your filing status on the Missouri return must match your federal return unless you qualify for specific exceptions. A mismatch can cause processing errors or force the Department of Revenue to send your return for corrections.

Claiming Dependents Incorrectly

Dependents must be the same as those claimed on your federal return. Do not include yourself or your spouse. Each dependent provides a financial advantage, so accuracy is essential when claiming them.

Missing Signatures or Dates

Both spouses must sign a joint return. Returns without signatures are considered incomplete. Double-check that you have signed and dated your return before you submit it.

Rounding Errors and Math Mistakes

Always round to the nearest dollar. For example, $10.50 should be entered as $11. Simple math mistakes, even a one-dollar error, can delay your refund while the state verifies your information.

Frequently Asked Questions (FAQs)

How does my federal income tax return affect my Missouri state return?

Your Missouri return begins with the adjusted gross income listed on your federal income tax return. That number carries over directly, and then Missouri-specific adjustments apply. If you make mistakes on the federal filing, the error will also appear on your state return. By electronically filing both returns, you reduce the risk of calculation errors and keep the information consistent across filings.

Do I need a copy of my federal tax return to complete my Missouri forms?

Yes, your Missouri state return requires information copied directly from your federal tax return. Without it, you cannot accurately file your taxes. Filing software and tax preparation companies often allow you to import the federal data automatically, which speeds up the process and reduces errors. This makes direct or electronic filing options especially convenient since the two sets of information stay aligned.

What counts as income tax for Missouri filing purposes?

For Missouri’s 2014 return, income tax refers to the state tax you owe based on your adjusted gross income and credits. It is not the same as the withholding already taken from your paycheck. Filing software and tax service companies can help you calculate the correct amount. If you qualify for certain credits or exemptions, such as disability deductions, your final income tax liability may be reduced.

Can I use Free File to submit my Missouri 2014 tax return?

Yes, Missouri partnered with IRS-approved companies to offer Free File for eligible taxpayers in 2014. This allowed individuals with income below certain thresholds to file federal and state electronic returns at no cost. Free File helps you file your taxes quickly, often with the option of direct filing. This service is safer than mailing paper forms and gives you faster refund access.

What if I make a mistake when I file my taxes for Missouri in 2014?

If you realize after submitting that your Missouri return has an error, you may request an amendment using Form MO-1040. Do not ignore the mistake; it can delay refunds or increase penalties. Electronically filing an amended return is not allowed for this year, so you must submit a paper form by mail. Companies that provide tax services can assist if the error involves disability or credit claims.
