What is Form 4714?
Form 4714, the 2026 Tax Calendar, is the Missouri Department of Revenue publication that shows, month by month, when Missouri tax returns, reports and payments are due, with the department's taxpayer assistance phone numbers and a note on alternative filing methods.
The printed revision is "Revised 12-2025". It opens with the Taxation Division's phone numbers for individual income tax, sales and use tax, financial institution taxes, corporation income and pass-through entity tax, fuel tax, withholding tax, account resolution, electronic filing, tire and battery fee, cigarette and tobacco taxes, business tax registration and marijuana tax. It then gives twelve monthly grids for January through December 2026. Each grid marks holidays, recurring items such as the quarter-monthly withholding and sales tax payments, and the days that have a longer list of due items. Those lists sit under the month.
Examples of what the lists cover: annual, monthly and quarterly sales and use tax and withholding tax returns; Form MO W-3 (separate dates for the electronic-required and paper-required versions); estimated tax declarations such as MO-1040ES and MO-1120ES; and the April 15 calendar-year forms, among them MO-1040, MO-1040A, MO-PTC, MO-1041, MO-1065, MO-1120, MO-1120S and MO-PTE. Lines for returns filed with an extension, such as MO-1040, MO-1120, MO-1120S, MO-1065 and MO-PTE, are listed under October 15.
The calendar notes that due dates shown for corporation income are based on calendar year filers. It is a reference, not a return: it reports nothing to the Department. The agency's forms page lists a separate 2025 edition of Form 4714.
Who needs to file Form 4714?
Missouri taxpayers and businesses that file returns, reports or payments with the Missouri Department of Revenue use the Tax Calendar to find the date each one is due. The calendar covers:
- individuals, for items such as MO-1040ES estimated tax and the April 15 individual forms;
- employers and sellers, for withholding tax and sales and use tax returns and the quarter-monthly payments;
- corporations, partnerships, fiduciaries and pass-through entities, for the income tax returns, estimated tax and extension lines;
- motor fuel, cigarette, other tobacco products, marijuana, tire and battery fee and insurance tax filers, for their monthly and quarterly reports and payments.
Corporation income dates are based on calendar year filers, so a filer on a different year should check the Department before relying on them. The calendar does not say who is required to file a given return, so use the instructions for that return, or call the phone line listed for the tax, to confirm that you must file it.
When to file Form 4714
You do not file Form 4714. Consult it before each due date for the tax you handle. It covers calendar year 2026, and its last lines carry over to early 2027: the monthly Motor Fuel Suppliers Report on January 4, 2027 and the Quarter-Monthly Withholding and Sales Tax Payment on January 6, 2027.
The dates fall on a fixed rhythm. Quarter-monthly withholding and sales tax payments appear in nearly every week. Monthly returns and reports cluster at the start, middle and end of each month. The annual and extension items are dated individually: for example, 2025 annual sales and use tax and withholding tax returns on February 2, the April 15 calendar-year forms, and the extended returns listed under October 15. Some returns have two dates that depend on the version: for Form MO W-3, the calendar lists February 2 for the electronic-required version and March 2 for the paper-required one.
How to fill out Form 4714
Confirm the calendar year and revision
Check that the top of the page reads 2026 Tax Calendar, Form 4714 (Revised 12-2025). Items from January 2027 appear at the end of the December list.
Find your tax's phone line
Under Taxpayer Assistance Numbers and Addresses, locate your tax, for example Sales and Use Tax, Withholding Tax or Individual Income Tax, and note its number. Use it to confirm a due date.
Locate the month on the grid
Each month has a Sunday-to-Saturday grid. Holidays, quarter-monthly withholding and sales tax payments and some reports are written in the day boxes.
Read the list under the month
Where a day box says See below for items due on this day, find that date in the list at the bottom of the month, such as January 15 or April 15, and read every item.
Check how the item is filed or paid
Read the alternative filing methods near the top. Quarter-monthly sales and withholding tax payments require an alternative payment method, and paper vouchers are not offered.
Watch the corporation and extension notes
Corporation income dates assume a calendar year filer. Extended returns are listed on their own dates, such as October 15 for MO-1040 with Extension.
Review and download the PDF
Check the dates against the return you need, then download or print the PDF from FillingPDF and keep it for reference. File each return or payment through the Department's channels.
How to submit Form 4714

Common mistakes to avoid
- Applying the corporation income due dates to a filer that is not on a calendar year; the calendar states that those dates are based on calendar year filers.
- Planning to pay quarter-monthly sales and withholding tax with a paper voucher; the calendar says an alternative payment method must be used and paper vouchers are not offered.
- Using the February 2 date for a paper-required Form MO W-3; the calendar lists paper-required Form MO W-3 on March 2 and the electronic-required version on February 2.
- Reading only the highlighted grid days and skipping the list under the month; days marked "See below for items due on this day" carry the actual return names.
- Treating April 15 as the only date for MO-1040, MO-1120, MO-1120S, MO-1065 or MO-PTE when the calendar lists a separate October 15 line for returns filed with an extension.
- Using the 2025 edition of Form 4714 for 2026 deadlines; the 2026 calendar is a separate edition.
- Calling the wrong phone line; the calendar gives a separate number for each tax, such as sales and use tax, withholding tax and corporation income tax.
