Every year, thousands of Missouri taxpayers face delays and frustration when filing their state tax return. In 2013, many residents missed out on timely refunds because of filing errors, incomplete forms, or failing to meet the official filing deadline. Even a simple mistake, like forgetting to round income correctly or leaving out a signature, can mean weeks of unnecessary waiting for your refund.

Filing your Missouri tax return for 2013 does not need to be stressful. You can file with confidence by using the correct forms, following state guidelines, and understanding how the process connects to your federal return. Whether you are a first-time filer or someone who wants to avoid penalties, this guide will walk you through the process outlined by the Missouri Department of Revenue.

This article will also highlight why filing early, electronically filing your return, and claiming all available deductions are crucial steps. Avoiding costly mistakes and missing deadlines can save money, prevent interest charges, and ensure your tax refund reaches your account quickly.

Who Needs to File in Missouri 2013

Not every Missouri resident or worker was required to direct file a state return for 2013, but overlooking the rules could mean losing money or facing penalties. Understanding exactly who must file is the first step in avoiding unnecessary costs.

Residents

If you were a full-year Missouri resident in 2013 and your Missouri adjusted gross income was $1,200 or more, you were required to file a tax return. You also needed to file if you had to submit a federal income tax return and your income exceeded your standard deduction plus exemption amount.

Nonresidents

Nonresidents who earned $600 or more in Missouri income during 2013 were required to file. Even if their primary residence was outside Missouri, income from Missouri sources, such as an employer, rental property, or business activity, meant they had to file a Missouri return.

Special Cases

  • If you were a Missouri resident with income below the threshold but an employer withheld taxes, you still needed to file to claim a refund.

  • Taxpayers receiving disability income or pension benefits had to check exemption eligibility before deciding whether a return was required.

  • Married couples filing jointly were required to split income between spouses, using worksheets provided by the Missouri Department of Revenue.

Why It Matters

Failing to determine your filing obligation correctly could cost you in two ways: by missing a refund you were eligible to claim or by accumulating penalties and interest if you owed money. Filing even when you think you may not need to is often safer.

Missouri Forms You Must Use

Choosing the proper Missouri tax form in 2013 was not optional but essential. The Missouri Department of Revenue provided two primary forms for individual income tax returns, and selecting the wrong one could cause delays, rejections, or lost refunds.

MO-1040 (Long Form)

The MO-1040 is Missouri’s comprehensive income tax form. You had to complete this form if your situation included:

  • Claiming credits for taxes paid to another state.

  • Reporting modifications from partnerships, trusts, or S corporations.

  • Claiming deductions for dependents age 65 or older.

  • Handling pension, Social Security, or military exemptions with added complications.

This form covered every possible scenario but also required more details, additional schedules, and careful review before you sign. It was the safest choice if you were uncertain about eligibility.

MO-1040P (Short Form)

The MO-1040P was designed for taxpayers with simpler situations. You could use this form if you were claiming only the property tax credit or straightforward pension exemptions. The advantage of this form was that it was shorter and faster to complete, but not everyone could use it. If your financial situation was complex, you were not eligible for this option.

Printable and Fill-in Forms

The Missouri Department offered fill-in forms on its official site that calculated amounts automatically and printed with a 2-D barcode. This feature reduced errors and sped up the process when mailed. Taxpayers could also download and print blank forms, which required careful math and double-checking.

How to Decide Which Form to File

When choosing between MO-1040 and MO-1040P, think about your income and credits:

  • The long form was required if you had multiple income sources, business activity, or out-of-state credits.

  • The short form was allowed if your only concern was claiming a credit for property tax or a pension exemption.

  • When in doubt, the long form was safer to complete, even though it took longer.

Using the correct form ensured that your tax return was processed quickly and that you claimed all eligible credits. Choosing incorrectly could have slowed your refund or created extra work to amend your return later.

Step-by-Step Process to Complete Your Return

Filing your Missouri state tax return for 2013 required careful attention to detail. By breaking the process into clear steps, taxpayers could avoid costly errors, claim every eligible credit, and ensure refunds were not delayed.

Step 1: Filing Status and Personal Information

Start by completing your federal return. Missouri requires this as the foundation for your state filing. Then enter your name, address, and Social Security number. Married couples filing jointly must split income between spouses using the state’s worksheet. If you or your spouse were disabled, blind, or over 65, you needed to check the proper boxes, which affected the property tax credit.

Step 2: Report Federal Adjusted Gross Income

On Line 1 of the Missouri return, transfer your federal adjusted gross income directly from your IRS form (Form 1040, 1040A, or 1040EZ). This step seems crucial but straightforward since all state calculations are based on it. Mistakes here create a chain reaction of errors throughout the return.

Step 3: Apply Missouri Modifications

Use Form MO-A to list any income modifications. Examples include interest on federal tax-exempt bonds (an addition) or Missouri bond interest (a subtraction). Pension, disability, and Social Security exemptions also fall under this step. Failing to complete these modifications correctly could mean you overpay or underpay your Missouri taxes.

Step 4: Deductions and Credits

Decide whether to claim the standard deduction or itemize. For 2013, the standard deduction amounts were $6,100 for single filers, $12,200 for married filing jointly, and $8,950 for head of household. If you itemized at the federal level, you were also required to itemize at the state level. Dependents also mattered: each dependent reduced taxable income by $1,200, with an additional $1,000 if the dependent was 65 or older.

Federal tax paid could also be deducted, but only up to $5,000 for most filers or $10,000 for married couples filing jointly. This deduction did not include federal withholding; it referred to the federal income tax owed for that year.

Step 5: Attach All Required Documents

When mailing your return, you needed to attach:

  • Pages 1 and 2 of your federal return.

  • All W-2s are showing Missouri withholding from your employer.

  • Any 1099 forms with Missouri income.

  • Form MO-A if you claimed modifications.

  • Schedule A if you itemized.

Leaving out even one W-2 or attachment was one of the most common reasons refunds were delayed.

Step 6: Double-Check for Common Errors

Before signing your return, check for these frequent mistakes:

  • Forgetting signatures from both spouses on a joint return.

  • Rounding amounts incorrectly (Missouri required rounding to the nearest dollar).

  • Choosing the wrong deduction type.

  • Failing to split income between spouses.

  • Mailing to the wrong address.

Why This Step-by-Step Process Matters

Taxpayers who completed these steps carefully were far less likely to face penalties or refund delays. Missouri refunds could take eight weeks or more if mistakes were made, while accurate electronically filed returns were often paid out within 30 days. Taking the time to prepare your return properly not only protects your money but also ensures peace of mind.

Filing Methods: Electronic vs. Paper

How you decided to file your Missouri tax return for 2013 was just as important as what you reported. The Missouri Department of Revenue encouraged taxpayers to file electronically because it reduced errors, improved security, and sped up refunds. Still, some taxpayers preferred paper forms. Knowing the differences helped you choose the method that saved the most time and money.

Electronically Filing (E-File)

Many taxpayers chose e-file because of its convenience and faster processing.

  • Refunds were typically issued within 10 to 30 days, depending on the season.

  • The error rate was significantly lower than that of paper forms, thanks to built-in checks.

  • Direct deposit allows refunds to go straight into your bank account.

  • Services included free options for eligible taxpayers and paid providers for more complex returns.

  • An immediate acknowledgment from the Missouri Department confirmed your return was received.

Paper Forms

Paper filing was still available for taxpayers who preferred traditional methods, but it had drawbacks.

  • Refunds could take 8 to 12 weeks, which meant waiting twice as long as electronic filers.

  • Errors were more common since taxpayers had to calculate amounts by hand.

  • Costs included postage, and returns could be delayed if mailed to the wrong address.

  • Paper filers had to choose the correct mailing address depending on whether they expected a refund or had a balance due.

  • Missouri’s fill-in forms with 2-D barcodes helped speed processing, but were not as fast as e-filing.

The decision between e-filing and paper filing could affect both time and money. Filing electronically gave taxpayers faster access to their refunds and fewer headaches caused by mistakes. Paper filing was still accepted, but it was a painfully slow process compared to modern e-file options.

Payment Options and Penalties

Once you completed your Missouri tax return for 2013, the next step was to ensure any balance due was paid correctly and on time. The filing deadline for calendar year taxpayers was April 15, 2014. Filing an extension gave you more time to send in your forms, but did not extend the time to pay. If you owed money, the amount had to be paid by April 15 to avoid penalties and interest.

How to Pay Your Missouri Taxes

The Missouri Department of Revenue offered several convenient payment methods in 2013:

  • Electronic Bank Draft (E-Check): Taxpayers can pay directly from a checking account online or by phone. A small convenience fee applies.

  • Credit Card Payments: Visa, MasterCard, Discover, and American Express were accepted through the state’s online portal or automated phone system. The third-party vendor charged a processing fee.

  • Check or Money Order: Payments could be mailed with the return or sent separately using Form MO-1040V, the payment voucher. Checks had to be made payable to the Missouri Department of Revenue.

  • Installment Options: If you could not pay in full, the Department allowed certain taxpayers to request a payment plan using Form 5708. Interest charges continued to apply, but paying in installments was better than failing to pay at all.

Penalties and Interest

Failing to pay on time carried costly consequences:

  • Late Payment Penalty: 5% of the unpaid tax if not paid by the deadline.

  • Late Filing Penalty: 5% of the unpaid tax for each month past the due date, up to 25%.

  • Interest: Charged on all unpaid balances at a variable annual rate.

For example, a taxpayer who owed $1,200 and filed two months late could face a late filing penalty of $120 (5% each month) plus the 5% late payment penalty of $60, along with interest charges. The total cost could rise above $200 simply because of missing the deadline.

Why Payment Compliance is Crucial

Taxpayers who paid on time avoided unnecessary costs and stress. Ignoring payment deadlines did not erase the debt; instead, it increased it month after month. Paying even part of the balance by the due date helped minimize penalties and interest, making it an essential step in protecting your money.

Tracking Refunds and Balances

Once your Missouri tax return 2013 was filed, the next concern was knowing when your tax refund would arrive or confirming how much you still owed. The Missouri Department of Revenue offered multiple ways for taxpayers to track this information, giving peace of mind during a stressful season.

Online Refund Tracking

The fastest method was through the Department’s official online service. By entering your Social Security number, filing status, and the exact refund amount in whole dollars, you could check the status of your return at any time. This service provided up-to-date details on whether your return was being processed, approved, or scheduled for payment.

Automated Phone System

Missouri also maintained an automated phone line available 24 hours a day for taxpayers without internet access. This system used the same information as the online tracker and provided a reliable alternative.

Processing Timelines

Refunds were not all processed equally.

  • Electronically filed returns with direct deposit were often completed in about 30 days.

  • Paper returns could take 8 to 12 weeks, particularly during peak filing season.

  • Many delays came from mistakes, such as missing W-2s or incorrect bank account details.

Checking your refund status regularly allowed you to catch problems early, such as rejected bank accounts or unprocessed documents. For those who owed money, monitoring your account balance helped ensure payments were credited correctly, preventing extra penalties and interest. Using the state’s refund tracking service was a simple way to protect your refund and peace of mind.

Final Filing Checklist

Before mailing or submitting your Missouri tax return for 2013, it was essential to review a checklist to avoid costly errors. A few minutes of preparation could mean a smooth refund and months of unnecessary delays.

Pre-Filing Review

  • Ensure your federal return is complete first, since Missouri requires this as the starting point.

  • Decide whether you should claim the standard deduction or itemize, based on your income and expenses.

  • Determine whether you are eligible for exemptions, such as those for dependents or disability income.

Documentation Essentials

  • Include pages 1 and 2 of your federal return and your Missouri forms.

  • Attach all W-2s showing Missouri withholding from your employer.

  • Provide 1099s for any other Missouri income and Form MO-A if you claimed modifications.

  • Sign the return before mailing, and ensure both spouses sign if filing jointly.

Accuracy and Submission

  • Double-check Social Security numbers, bank account details, and rounding of all amounts.

  • Confirm that you are mailing to the correct address, depending on whether you expect a refund or owe money.

  • Keep a printed copy of your entire return and all supporting documents for your records.

Completing this checklist reduced the chance of refund delays or penalty notices. Taxpayers who followed every step had greater confidence that the Missouri Department of Revenue would process their return accurately.

Frequently Asked Questions (FAQs)

How long does it take to get my Missouri tax refund for 2013?

Most tax refunds from the Missouri Department of Revenue were issued within 30 days if filed electronically with direct deposit. Paper returns could take 8 to 12 weeks. Delays often occurred when taxpayers left out forms or made errors. To qualify for the fastest refund, it was always best to e-file, double-check all attachments, and use the refund tracking service provided by the MO Department.

Who needed to file an income tax return in Missouri for 2013?

Missouri residents with $1,200 or more in adjusted gross income and nonresidents with $600 or more in Missouri income had to file a state return. Even if your income was below these levels, you should still file to qualify for a refund if an employer withheld taxes. The MO Department required married couples to split income correctly, and special rules were applied to those claiming disability exemptions.

What if I missed the filing deadline for my 2013 Missouri return?

If you missed the April 15, 2014, deadline, you could still file your return, but penalties and interest would apply if you owed money. Filing late reduced your refund only if you waited too long since refunds generally had to be claimed within three years. Taxpayers were encouraged to pay as much as possible up front to qualify for reduced penalties and contact the MO Department for installment options.

Can small businesses file a Missouri income tax return separately?

Yes, businesses with Missouri-sourced income were required to file if they met the thresholds set by the MO Department. Sole proprietors reported business activity on their return, while partnerships and corporations filed separate forms. It was essential to keep detailed records and file on time to qualify for business-related credits or deductions. The MO Department also provided resources for small businesses to manage extensions and payment options.

What happens if I owe Missouri income tax but cannot pay in full?

Taxpayers who owed money but could not pay in full were not excused from filing. Instead, the MO Department allowed installment payment options through Form 5708. You had to submit the form, pay as much as possible by the filing deadline, and agree to interest charges to qualify. Ignoring the debt only increased costs, since penalties accumulated each month. Contacting the MO Department immediately was always the best course of action.
