Federal income tax withheld from employee paychecks is due on either a monthly or a semi-weekly deposit schedule, and the IRS decides which one applies to you before the year begins. Monthly depositors send in each month’s withholding by the 15th of the following month. Semi-weekly depositors deposit by the Wednesday after a Wednesday–Friday payday, or by the Friday after a Saturday–Tuesday payday. A separate rule overrides both: any single day you accumulate $100,000 or more in employment tax liability, you must deposit by the next business day.1Internal Revenue Service. Topic No. 757, Forms 941 and 944 – Deposit Requirements
How the IRS Decides Which Schedule You Follow
Your schedule for a calendar year is set by a lookback period, not by your current payroll. For Form 941 filers, the lookback covers four quarters running from July 1 of the second preceding year through June 30 of the prior year. For 2026, that window is July 1, 2024 through June 30, 2025.2Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide
Add up Line 12 from each Form 941 filed during that window. Total of $50,000 or less puts you on the monthly schedule. More than $50,000 puts you on the semi-weekly schedule.2Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide3Internal Revenue Service. Instructions for Form 941
New employers are monthly depositors by default, because the lookback liability for any quarter before the business existed is treated as zero.1Internal Revenue Service. Topic No. 757, Forms 941 and 944 – Deposit Requirements The classification is rolled forward every December, so check the math before each new year.
Monthly Deposit Deadlines
If you are a monthly depositor, everything withheld during a calendar month is due by the 15th of the following month. January withholding is due February 15. February withholding is due March 15. And so on.
When the 15th falls on a Saturday, Sunday, or a legal holiday in the District of Columbia, the deadline shifts to the next business day.1Internal Revenue Service. Topic No. 757, Forms 941 and 944 – Deposit Requirements A holiday observed only in your state does not extend the deadline.
Semi-Weekly Deposit Deadlines
Semi-weekly depositors work off the day the wages were paid, not the pay period they covered:
- Payday on Wednesday, Thursday, or Friday: deposit by the following Wednesday.
- Payday on Saturday, Sunday, Monday, or Tuesday: deposit by the following Friday.
The IRS builds in at least three business days between the end of a semi-weekly period and the deposit due date. If any weekday in that three-day span is a legal holiday in the District of Columbia, the deadline moves one day for each such holiday.1Internal Revenue Service. Topic No. 757, Forms 941 and 944 – Deposit Requirements
The name is misleading. “Semi-weekly” refers to the two possible deposit windows in a week, not to how many deposits you make. If you run payroll once a week, you make one deposit that week.
The $100,000 Next-Day Rule
Any day your accumulated employment tax liability reaches $100,000 or more, the deposit is due by the next business day. This applies whether you are normally monthly or semi-weekly.4GovInfo. 26 CFR 31.6302-1 – Deposit Rules for Taxes Under FICA and Withheld Income Taxes
Crossing this threshold has an aftereffect. Once you trip it, you are reclassified as a semi-weekly depositor for the rest of the current calendar year and all of the next one.5eCFR. 26 CFR 31.6302-1 – Deposit Rules for Taxes Under the Federal Insurance Contributions Act (FICA) and Withheld Income Taxes A one-off large payroll, such as year-end bonuses, can quietly change your schedule for the following year.
When You Can Skip Deposits Entirely
If your total Form 941 tax liability for either the current quarter or the preceding quarter is under $2,500, you can skip deposits for that quarter and pay the full balance with the return itself.1Internal Revenue Service. Topic No. 757, Forms 941 and 944 – Deposit Requirements Hitting the $100,000 next-day threshold at any point in the quarter cancels this exception.
Form 944 filers get an equivalent break: annual liability under $2,500 can be paid with the return instead of on a deposit schedule.6Internal Revenue Service. Instructions for Form 944 You cannot pick Form 944 on your own; the IRS has to notify you or approve a request to use it.
How to Actually Pay on Time
Deposits have to be made electronically. The main channel is EFTPS, the Electronic Federal Tax Payment System, which is free to use once you have enrolled and received a PIN. There is a cutoff most people miss on their first try: payments must be scheduled by 8:00 p.m. Eastern time the day before the deposit is due.7Electronic Federal Tax Payment System. About the Electronic Federal Tax Payment System A payment scheduled at 9 p.m. the night before will not settle in time.
If you miss that cutoff, a same-day wire through your bank is the backup. You complete the IRS Same-Day Taxpayer Worksheet and your financial institution transmits the payment. Ask your bank about availability, fees, and their own cutoff before you need it.8Internal Revenue Service. Same-Day Wire Federal Tax Payments
An employer required to deposit electronically who pays some other way faces a 10% penalty on the deposit amount, even when the payment itself arrives on time.9Internal Revenue Service. 20.1.4 Failure to Deposit Penalty
Deposits Versus the Quarterly Return
Deposits and returns are separate deadlines. Form 941, which reconciles wages paid, tax withheld, and deposits made, is due April 30, July 31, October 31, and January 31 for the four calendar quarters. Employers who made every deposit for the quarter on time and in full get an automatic 10 extra calendar days to file the return.10Internal Revenue Service. Employment Tax Due Dates Filing the return is not a substitute for depositing during the quarter, and depositing is not a substitute for filing.
Penalties for Late Deposits
Section 6656 penalties escalate with how far past the deadline the deposit lands:
- 1 to 5 days late: 2% of the unpaid deposit
- 6 to 15 days late: 5%
- More than 15 days late: 10%
- More than 10 days after the first IRS delinquency notice, or upon a notice demanding immediate payment: 15%
The tiers do not stack. A deposit 20 days late incurs the 10% rate, not the sum of the earlier tiers.11Internal Revenue Service. Failure to Deposit Penalty The IRS may waive the penalty on a showing of reasonable cause and no willful neglect.12Office of the Law Revision Counsel. 26 US Code 6656 – Failure to Make Deposit of Taxes
Interest runs on top of the penalty. The underpayment rate is 7% per year, compounded daily, for the first quarter of 2026,13Internal Revenue Service. Interest Rates Remain the Same for the First Quarter of 2026 and 6% starting in the second quarter of 2026.14Internal Revenue Service. Internal Revenue Bulletin 2026-8 Interest accrues from the original due date to the day you pay.
Why Missing These Deadlines Is Personally Dangerous
Withheld income tax, together with the employee share of Social Security and Medicare, is a trust fund tax. The employer is holding the money for the government until it is deposited. When a business fails to deposit those funds, the IRS can assess the Trust Fund Recovery Penalty under Section 6672 against the individuals who controlled the money. The penalty equals the entire unpaid trust fund amount, not a percentage of it.15Internal Revenue Service. Employment Taxes and the Trust Fund Recovery Penalty (TFRP)
Two elements have to be established. First, you have to be a “responsible person,” meaning someone with authority over which creditors get paid. The IRS applies this broadly: corporate officers, directors, shareholders, LLC members, bookkeepers, and even payroll service providers can qualify. Second, the failure has to be “willful,” which here means knowingly choosing to pay other bills instead of depositing withheld tax. Intent to defraud is not required.16Internal Revenue Service. Trust Fund Recovery Penalty (TFRP) Overview and Authority
More than one person inside the same business can be held liable for the same unpaid taxes, and the IRS can collect from each through liens and levies on personal assets.17Office of the Law Revision Counsel. 26 US Code 6672 – Failure to Collect and Pay Over Tax, or Attempt to Evade or Defeat Tax If you cannot make a deposit, do not quietly move the money elsewhere.
