Form 941, deposits, FUTA, and state filings — mapped
As an active S corporation owner-employee, you're responsible for more than just filing Form 941 each quarter. Payroll tax deposits, filing deadlines, unemployment taxes, and state requirements all follow their own schedules.
Missing a deadline can lead to penalties, while staying organized can help keep payroll tax routine. Understanding how the pieces fit together can help you build a system that can help you keep your S-corp payroll on track throughout the year.
SurePayroll® By Paychex calculates, deposits and files federal and state payroll taxes on your schedule.
Know which S-corp tax obligations are payroll taxes
Form 941 is the employer-side payroll tax return. Use it to report federal income tax withheld from wages, plus Social Security and Medicare (FICA) taxes owed by both the employee and employer. For an active S-corp owner-employee, that includes payroll taxes tied to the reasonable salary paid through the business. File Form 941 four times a year to meet your federal employer payroll tax reporting requirements.
Beyond Form 941, employers may also have payroll tax deposit requirements, federal unemployment tax obligations, and state payroll tax filing responsibilities. Each requirement follows its own schedule, making it important to understand which deadlines apply to your business.
Note on Form 944: Form 944 is an annual alternative for employers whose total annual payroll tax liability is $1,000 or less. The IRS must notify you in writing if you’re eligible to file Form 944; you cannot self-select it. If you haven't received that notification, you file Form 941.
Form 941 covers and when it's due
Form 941 is your employer's quarterly federal tax return. You use it to report federal income taxes withheld from wages, including your own reasonable salary, the employee share of Social Security taxes and Medicare taxes, and your matching employer share of both.
When you file Form 941, you're reconciling your payroll tax deposit activity for the quarter -- what you owed against what you paid.
Your 2026 Form 941 filing deadlines
When a filing deadline lands on a weekend or federal holiday, you file the next business day.
The on-time depositor extension
When you deposit all payroll taxes in full and on time during a quarter, you may have 10 additional days to file. Your due date moves to the 10th of the second month after the quarter closes. Staying current on deposits can give you more runway on the filing itself.
How your deposit schedule works
Your deposit schedule determines when you pay the payroll taxes you withheld from wages. It runs separately from your Form 941 filing deadline and starts when you run your first payroll.
Monthly vs. semiweekly
The IRS assigns your deposit schedule based on your lookback period, which is based on total employment taxes you reported on Form 941 during the 12-month window ending June 30 of the prior year. If you’re a new S-corp employer, you start on the monthly deposit schedule.
If you accumulate $100,000 or more in taxes on any day during a deposit period, you must deposit the taxes by the next business day.
On the semiweekly schedule, the day your deposit is due depends on which day of the week you run payroll: paydays that fall Saturday through Tuesday mean a Friday deposit; paydays that fall Wednesday through Friday mean a Wednesday deposit.
Making your deposits
You make federal payroll tax deposits through the Electronic Federal Tax Payment System (EFTPS). Enrollment is free and EFTPS helps maintain your deposit history in one place.
Check your schedule each year
Confirm your schedule at the start of each year. The IRS can reassign it based on your lookback period, so make sure you're using the right one.

FUTA: The annual filing with quarterly checkpoints
Federal Unemployment Tax Act (FUTA) is an employer-only tax. Your employees don't pay it, you do. It funds federal unemployment insurance.
If your S-corp pays you or other employees $1,500 or more in wages in any calendar quarter, or has one or more employees for at least part of a day in 20 or more different weeks, the business may be subject to FUTA and must file Form 940.
The gross FUTA rate is 6% on the first $7,000 you pay each employee per year. When you pay your state unemployment taxes (SUI) on time and your state is not a credit reduction state, you may qualify for a tax credit of up to 5.4%, which brings your effective federal rate down to 0.6%. A late or missed SUI payment can cost you that credit.
You file Form 940 once a year by January 31. During the year, make a deposit any quarter your cumulative FUTA liability exceeds $500. If your liability stays at or under $500 for the full year, you pay the balance with your annual filing.
State payroll tax filings: what runs in parallel
You have state payroll tax obligations as well as federal ones. The schedule and forms vary by state, but the categories are consistent: withholding returns, state unemployment insurance filings, and multi-state obligations if you have employees in more than one state.
State income tax withholding
In states with income tax withholding requirements, you generally file withholding returns on a state-set schedule. Most states run quarterly, but filing frequency varies by state and by your total withholding volume. Your state revenue department sets your schedule and deposit thresholds.
State unemployment insurance
Most states require quarterly SUI filings. Staying current on SUI payments also helps you protect your FUTA credit. Keep SUI deadlines in the same calendar as your federal obligations.
Multi-state payroll
If you have employees working in multiple states, you carry state payroll tax obligations in each state where those employees work, not just where your S-corp is based.
Where to get the specifics
State forms, deadlines, and deposit thresholds vary by state. Your state revenue department publishes the authoritative requirements for your location. Build those deadlines into the same calendar you use for your federal filings, whether you track manually or through payroll software.
