Electronic Filing Options for Federal and State E-File - Missouri, in cooperation with the Internal Revenue Service (IRS), offers a joint federal and state filing of individual income tax returns. There are two ways that you may e-file your federal and state income tax returns: 1) You can electronically file your federal and state returns online from websites provided by approved software providers. Many providers offer free filing if you meet certain conditions. A list of approved providers can be found at dor.mo.gov/taxation/individual/tax-types/income/efile.html. The Individual Income Tax Return (Form MO-1040) is Missouri’s long form. It is a universal form that can be used by any individual taxpayer. If you do not have any of the special filing situations described below and you choose to file a paper tax return, try filing a short form (Form MO-1040A). The short forms are less complicated and provide only the necessary information for specific tax filing situations. 2) You can have a tax preparer (if approved by the IRS) electronically file your federal and state returns for you, usually for a fee. A list of approved tax preparers can be found at dor.mo.gov/taxation/individual/tax-types/income/efile.html. You must file Form MO-1040 if at least one of the following applies: 1. You or your spouse claim or file: a. A pension, social security/social security disability, or property tax credit and you also have other special filing situations; b. Miscellaneous Income Tax Credits (taken on Form MO-TC); c. A credit for payment made with the filing of an Application for Extension of Time to File (Form MO-60); d. Income from another state; e. An amended return; f. A nonresident entertainer or a professional athlete; g. A fiscal year return; h. A nonresident military servicemember stationed in Missouri and you or your spouse earned non-military income while in Missouri; i. A deduction for other federal tax (from Federal Form 1040, Federal Schedule 2, and Federal Schedule 3); • Schedule 2, Part 1, Line 3; • Schedule 2, Part 2, Lines 8, 14, and 15; • Any recapture taxes included on Schedule 2, Part 2, Line 21; • Schedule 3, Part 1, Line 1; j. A Health Care Sharing Ministry deduction; k. Any Military income earned from: *Active Duty *Inactive Duty l. Farmland sold, rented, leased, or crop-shared to a beginning farmer deduction; m. Foster Parent tax deduction; or n. Missouri Working Family Tax Credit. BENEFITS OF ELECTRONIC FILING Convenience: You can electronically file 24 hours a day, 7 days a week. If you electronically file, DO NOT mail a copy of your return. Security: Your tax return information is encrypted and transmitted over secure lines to ensure confidentiality. Accuracy: Electronically filed returns have fewer errors than paper returns. Direct Deposit: You can have your refund directly deposited into your bank account. Proof of Filing: An acknowledgment is issued when your return is received and accepted. ASSISTANCE WITH PREPARING YOUR TAX RETURN There are a large number of volunteer groups in Missouri providing tax assistance to elderly or lower income taxpayers. To locate a volunteer group near you that offers return preparation assistance: call 800-906-9887, 888-227-7669 or visit irs.gov/individuals.

EXTENSION OF TIME TO FILE This information is for guidance only and does not state the complete law.

If you wish to file a Missouri extension, and do not expect to owe Missouri income tax, you may file an extension by filing Form MO-60. An automatic extension of time to file will be granted until October 15, 2026. FILING REQUIREMENTS You do not have to file a Missouri return if you are not required to file a federal return. If you are required to file a federal return, you may not have to file a Missouri return if you: If you receive an extension of time to file your federal income tax return, you will automatically be granted an extension of time to file your Missouri income tax return.

If you are not required to file a Missouri return and you do not anticipate an increase in income, you may change your Employee Withholding Allowance Certificate (Form MO W-4) to “exempt” so your employer will not withhold Missouri tax.

Exception: An individual domiciled in Missouri who did not maintain permanent living quarters in Missouri, did maintain permanent living quarters elsewhere, and spent 30 days or less of the taxable year in Missouri is not a resident. Domicile: The place an individual intends to be his or her permanent home; a place that he or she intends to return to when absent. A domicile, once established, continues until the individual moves to a new location with the true intention of making his or her permanent home there. An individual can have only one domicile at a time. NONRESIDENT A nonresident is an individual who does not meet the definition of resident. If required to file, nonresidents with income from another state must use the Missouri Income Percentage (Form MO-NRI) to determine income percentages.

If you selected filing status married filing separate and did not claim your spouse as an exemption on Federal Form 1040NR, select married filing separate as your filing status on Form MO-1040. If you selected filing status qualifying surviving spouse on Federal Form 1040NR, select qualifying widow(er) as your filing status on Form MO-1040. Non-Missouri Home of Record (Stationed in Missouri) The military pay of a nonresident military personnel stationed in Missouri due to military orders is not taxable to Missouri.

PART-YEAR RESIDENT All income earned while living in Missouri is taxable to Missouri. A part-year resident may determine to be taxed as a resident for the entire year by using the Credit for Income Taxes Paid to Other States or Political Subdivisions (Form MO-CR) to claim a credit for taxes paid to another state on the income earned while living in Missouri. Or a part-year resident may use Missouri Income Percentage (Form MO-NRI) to determine their income based on the income earned while living in Missouri. OTHER STATE INCOME You must begin Form MO-1040 with your total federal adjusted gross income, as reported on your federal return. Lines 1 through 30 of the return are computed as if you are a full-year resident. Tax (Line 30) is computed on all your income, and may then be reduced by a resident credit (Line 31), or by a Missouri income percentage (Line 32). The result is a prorated Missouri tax liability based only on the income earned in Missouri. See page 9, Lines 31 and 32. MILITARY PERSONNEL The Servicemembers Civil Relief Act prevents military personnel from being taxed on military income by any state other than their home of record state. The Military Spouses Residency Relief Act prevents income earned by servicemembers’ spouses from being taxed by any state other than their state of residence.

Use tax is imposed on the storage, use or consumption of tangible personal property in this state. The state use tax rate is 4.225 percent. Cities and counties may impose an additional local use tax.

If you are filing a fiscal year return, indicate the beginning and ending dates on the line provided near the top of Form MO-1040. Missouri requires the division of income between spouses. Taxpayers filing a combined return pay less tax by dividing the income between spouses and then determining the tax amount for each person’s income. You must begin your Missouri return with your total federal adjusted gross income, even if you have income from a state other than Missouri. FEDERAL EXTENSION Select the box at the top of the form indicating you have an approved federal extension and attach a copy of your application for federal extension (Federal Form 4868) with your Missouri Income tax return when you file. Failure to check this box may result in disallowing the extension. LINE 1 - FEDERAL ADJUSTED GROSS INCOME If your filing status is married filing combined (MFC) and both spouses are reporting income, use the worksheet on page 7 to split income between you and your spouse. The combined income for you and your spouse must equal the total federal adjusted gross income you reported on your federal return. For all other filing statuses, use the chart below to determine your federal adjusted gross income. FILING STATUS Select the same filing status on your Missouri return as claimed on the federal return. If on your federal return you selected the checkbox “Someone can claim you as a dependent,” you will select “claimed as a dependent” on the Form MO-1040. If on your federal return you selected the checkbox “Someone can claim you as a dependent,” and your federal return status is married filing jointly, you will select the filing status of “married filing combined” on the Form MO-1040. Federal Form Federal Form 1040 or Federal Form 1040-SR Federal Form 1040X AGE 62 THROUGH 64 Line Numbers Line 11a Line 1 Negative Federal Adjusted Gross Income If you or your spouse were ages 62, 63, or 64 by December 31, 2025, select the appropriate box. Based on the Missouri State Code of Regulation 12 CSR 10-2.710, an individual taxpayer cannot have a negative federal adjusted gross income (FAGI) for purposes of computing Missouri adjusted gross income. An individual who, for federal income tax purposes, has a negative FAGI for a given tax year, must calculate Missouri adjusted gross income as if their FAGI was zero dollars ($0). For all filing statuses except for married filing combined, if your FAGI reported on Federal Form 1040, Line 11a, is negative, enter $0 on Form MO-1040, Line 1Y.

Worksheet for Line 1 - Instructions for Completing the Adjusted Gross Income Worksheet Missouri law requires a combined return for married couples filing together. A combined return means taxpayers are required to split their total federal adjusted gross income (including other state income) between spouses when beginning the Missouri return. Splitting the income can be as easy as adding up your separate Form(s)W-2 and Form(s) 1099. Or it may require allocating to each spouse the percentage of ownership in jointly held property, such as businesses, farm operations, dividends, interest, rent, and capital gains or losses. State refunds should be split based on each spouse’s 2024 Missouri tax withheld, minus each spouse’s 2024 tax liability. The result should be each spouse’s portion of the 2024 refund. Taxable social security benefits must be allocated by each spouse’s share of the benefits received for the year. The worksheet below lists income that is included on your federal return, along with federal line references. Find the lines that apply to your federal return, split the income between you and your spouse, and enter the amounts on the worksheet. When you have completed the worksheet, transfer the amounts from Line 11 to Form MO-1040, Lines 1Y and 1S. Note: Remember, the incomes listed separately on Line 11 of this worksheet must equal your total federal adjusted gross income when added together.

About the Individual Income Tax
The IRS and most states collect a personal income tax, which is paid throughout the year via tax withholding or estimated income tax payments.
Most taxpayers are required to file a yearly income tax return in April to both the Internal Revenue Service and their state's revenue department, which will result in either a tax refund of excess withheld income or a tax payment if the withholding does not cover the taxpayer's entire liability. Every taxpayer's situation is different - please consult a CPA or licensed tax preparer to ensure that you are filing the correct tax forms!
