Federal Payroll Tax Filing Deadlines
Federal payroll tax requirements apply to all employers in St. Louis, regardless of size. These taxes fund various federal programs including Social Security, Medicare, and unemployment insurance. Understanding these deadlines is the foundation of proper payroll tax compliance. Effective time tracking tools can help ensure you have accurate records for these filings.
- Form 941 (Employer’s Quarterly Federal Tax Return): Due by the last day of the month following each quarter end (April 30, July 31, October 31, and January 31).
- Form 940 (FUTA Tax Return): Annual filing due by January 31 of the following year.
- Forms W-2 and W-3: Must be provided to employees by January 31 and filed with the Social Security Administration by January 31.
- Form 1099-NEC/1099-MISC: For independent contractors, due to recipients and the IRS by January 31.
- Federal Tax Deposits: Schedule varies based on employer size and tax liability (monthly or semi-weekly).
Businesses with a semi-weekly deposit schedule have a more complex timeline to manage, which makes payroll integration techniques particularly valuable. For these employers, payments must be made by Wednesday for payroll paid on Wednesday, Thursday, or Friday, and by Friday for payroll paid on Saturday, Sunday, Monday, or Tuesday. Missing these deadlines can trigger significant IRS penalties.
Missouri State Payroll Tax Filing Deadlines
In addition to federal requirements, St. Louis businesses must comply with Missouri state payroll tax deadlines. The primary state-level payroll taxes include withholding tax and unemployment insurance contributions. Implementing key scheduling features can help managers ensure they have adequate staffing to handle these periodic filing requirements.
- Missouri Employer’s Return of Income Taxes Withheld (Form MO-941): Filing frequency depends on the amount of taxes withheld (monthly, quarterly, or annually).
- Monthly Filers: Due by the 15th day of the following month.
- Quarterly Filers: Due by the last day of the month following quarter end (April 30, July 31, October 31, and January 31).
- Annual Filers: Due by January 31 of the following year.
- Missouri Unemployment Tax: Quarterly reports and payments due by the last day of the month following the quarter (April 30, July 31, October 31, and January 31).
Missouri employers should be aware that their filing frequency for state withholding taxes may change based on their withholding amounts. The Missouri Department of Revenue reviews filing status annually and notifies employers of any changes. Businesses experiencing growth should monitor their withholding amounts closely, as they may need to adjust their filing frequency. Workforce analytics can help identify trends that might affect your filing requirements.
St. Louis City-Specific Payroll Tax Requirements
St. Louis businesses face additional local tax requirements beyond federal and state obligations. The city’s unique tax structure includes an earnings tax that affects both businesses and employees. Compliance with labor laws at all levels is essential for St. Louis employers.
- St. Louis City Earnings Tax: Currently at 1% of gross income, withheld from employees who work in the city.
- Quarterly Returns: Due by the last day of the month following the quarter (April 30, July 31, October 31, and January 31).
- Annual Reconciliation: Form W-10 due by February 28 of the following year.
- Business License Renewals: Various deadlines based on business type, typically annual.
- Commercial Facilities Tax: For applicable businesses, due at various times throughout the year.
The St. Louis earnings tax applies to all employees who work within city limits, regardless of where they live. Employers must withhold this tax from employee paychecks and remit it to the city according to the established schedule. For businesses with employees who work partially in the city, special allocation rules may apply. Implementing mobile technology can help track employee work locations for proper tax allocation.
Deposit Schedules and Payment Methods
Understanding not just when to file but how to pay payroll taxes is crucial for St. Louis businesses. Different tax authorities offer various payment methods, and deposit schedules can vary based on business size and tax liability. Staff performance metrics can help ensure your payroll team is meeting these obligations consistently.
- Federal Tax Deposits: Most businesses must use the Electronic Federal Tax Payment System (EFTPS).
- Monthly Depositors: Pay by the 15th of the following month.
- Semi-Weekly Depositors: Pay based on payroll dates (Wednesday/Friday schedule).
- Next-Day Depositors: Businesses with $100,000+ in tax liability must deposit the next banking day.
- Missouri State Payments: Electronic filing available through the Missouri Department of Revenue website.
Your deposit schedule for federal taxes is determined by your lookback period, which is the four quarters beginning July 1 of the second preceding year and ending June 30 of the prior year. If you reported $50,000 or less during this period, you’re a monthly depositor. If you reported more than $50,000, you’re a semi-weekly depositor. New employers are automatically monthly depositors. Using employee management software can help track these thresholds and alert you to potential changes in your deposit schedule.
Electronic Filing Requirements
Increasingly, tax authorities at all levels are requiring electronic filing for payroll taxes. St. Louis businesses need to be aware of these requirements, which can vary by tax type and business size. Digital transformation examples in payroll processing show how businesses are adapting to these electronic filing mandates.
- Federal E-Filing: Required for businesses with 250+ W-2 forms (threshold decreasing to 100 in 2022, then 10 in 2023).
- Missouri E-Filing: Required for employers withholding $20,000+ in state taxes per year.
- E-Payment Systems: EFTPS for federal taxes, MO DOR website for state taxes, and St. Louis’s online portal for city taxes.

Electronic filing not only fulfills compliance requirements but also offers benefits like faster processing, reduced errors, and automatic confirmation of receipt.

Cloud computing solutions can provide secure, accessible platforms for managing electronic tax filings across federal, state, and local requirements.
Penalties for Missing Payroll Tax Deadlines
Missing payroll tax deadlines can result in significant financial penalties for St. Louis businesses. Understanding these potential consequences can help emphasize the importance of timely compliance. Risk mitigation strategies should include systems to prevent missed deadlines.

Beyond financial penalties, consistent failure to meet payroll tax deadlines can trigger audits and damage a business’s relationship with tax authorities. In severe cases, business owners and responsible parties can face personal liability for unpaid payroll taxes. Compliance training for staff handling payroll responsibilities can help prevent these costly mistakes.
Record-Keeping Requirements
