Federal payroll tax deadlines fall into two buckets. Deposits of withheld income tax and FICA are due either monthly (by the 15th of the following month) or semi-weekly (within a few days of each payday), depending on how much tax you reported in a prior 12-month lookback period. Quarterly returns on Form 941 are due April 30, July 31, October 31, and January 31. Miss a deposit and penalties start at 2% and climb to 15%, with personal liability possible for the trust fund portion.
How the IRS Decides Your Deposit Schedule
Your deposit frequency for the coming calendar year is set by a lookback period running July 1 through June 30 of the prior year. Add up the employment tax liability you reported on your quarterly returns over those four quarters. Report $50,000 or less and you deposit monthly. Report more than $50,000 and you deposit semi-weekly.1IRS. Notice 931 (Rev. September 2025) – Deposit Requirements for Employment Taxes
New employers with no filing history start out monthly, because the IRS treats the lookback liability as zero.2Internal Revenue Service. Topic No. 757, Forms 941 and 944 – Deposit Requirements If your status changes because of the lookback test, the IRS sends a CP236 notice, but that notice is a reminder rather than a prerequisite. Check your own numbers each October so you know your schedule before January.3Internal Revenue Service. Understanding Your CP236 Notice
Monthly and Semi-Weekly Deposit Due Dates
Monthly depositors total the employment tax liability from paychecks issued during a calendar month and deposit that amount by the 15th of the following month. When the 15th is a weekend or federal holiday, the deadline moves to the next business day.1IRS. Notice 931 (Rev. September 2025) – Deposit Requirements for Employment Taxes
Semi-weekly depositors run on a tighter cycle tied to actual payday:
- Paydays on Wednesday, Thursday, or Friday: deposit by the following Wednesday.
- Paydays on Saturday, Sunday, Monday, or Tuesday: deposit by the following Friday.
Weekends and holidays can extend those windows slightly.1IRS. Notice 931 (Rev. September 2025) – Deposit Requirements for Employment Taxes
The $100,000 Next-Day Rule
Accumulate $100,000 or more in tax liability on any single day during a deposit period, and the whole amount is due by the close of the next business day. This applies whether you’re normally monthly or semi-weekly.1IRS. Notice 931 (Rev. September 2025) – Deposit Requirements for Employment Taxes
There’s a follow-on effect: if you’re monthly and trigger the $100,000 rule, you become a semi-weekly depositor for the rest of that calendar year and the entire following calendar year.4Internal Revenue Service. Instructions for Form 941 (03/2026) One large payroll can reshape your deposit obligations for close to two years.
Deposits Must Be Electronic
All federal tax deposits have to move by electronic funds transfer. Acceptable channels include the Electronic Federal Tax Payment System (EFTPS), IRS Direct Pay, and your IRS business tax account.1IRS. Notice 931 (Rev. September 2025) – Deposit Requirements for Employment Taxes Mailing a paper check does not count as a valid deposit; using an unapproved method can trigger failure-to-deposit penalties even when the money arrives on time.
EFTPS enrollment takes about a week because the activation PIN is mailed to you. New employers should set this up before running the first payroll.
Penalties for Missing a Deposit
Failure-to-deposit penalties are graduated by how late the deposit is. Only one rate applies, based on the bracket the lateness falls into:5Internal Revenue Service. Failure to Deposit Penalty
- 1 to 5 calendar days late: 2% of the unpaid deposit.
- 6 to 15 calendar days late: 5% of the unpaid deposit.
- More than 15 calendar days late: 10% of the unpaid deposit.
- More than 10 days after the first IRS notice, or upon a demand for immediate payment: 15% of the unpaid deposit.
Those rates come from federal statute and are calculated on the shortfall, not your total liability.6Office of the Law Revision Counsel. 26 U.S. Code 6656 – Failure to Make Deposit of Taxes Interest also accrues on unpaid amounts. The IRS underpayment rate was 7% per year, compounded daily, for the first quarter of 20267Internal Revenue Service. Interest Rates Remain the Same for the First Quarter of 2026 and dropped to 6% for the second quarter.8Internal Revenue Service. Internal Revenue Bulletin 2026-08 The rate resets quarterly.
Quarterly Return Deadlines (Form 941)
Depositing and reporting are separate obligations. Most employers file Form 941 each quarter to report federal income tax withheld and the employee and employer shares of Social Security and Medicare:9Internal Revenue Service. Instructions for Form 941 (Rev. March 2026)
- First quarter (January–March): due April 30.
- Second quarter (April–June): due July 31.
- Third quarter (July–September): due October 31.
- Fourth quarter (October–December): due January 31.
If every deposit for the quarter was made on time and in full, you get an extra 10 calendar days to file the return. A fully compliant first-quarter filer, for example, has until May 10.9Internal Revenue Service. Instructions for Form 941 (Rev. March 2026)
Very small employers whose total annual liability for withholding and FICA is $1,000 or less can file Form 944 once a year (due January 31 of the following year) instead of filing 941 quarterly, but only if the IRS has notified you to use Form 944. You can’t switch on your own.10Internal Revenue Service. About Form 944, Employer’s Annual Federal Tax Return
W-2 and W-3 Deadlines
Employers must file Forms W-2 with the Social Security Administration to report each employee’s annual wages and withholding. For the 2026 tax year, both the employee copies and the SSA filing with the transmittal Form W-3 are due February 1, 2027.11Internal Revenue Service. 2026 General Instructions for Forms W-2 and W-3 Extensions are available through Form 8809 only for extraordinary circumstances.
If you file 10 or more information returns of any type during the year, you must file electronically. The threshold is your total across all return types, not each type on its own: an employer with six W-2s and five 1099-NECs is over the line and must e-file all of them.12IRS. Publication 1099 General Instructions for Certain Information Returns (For Use in Preparing 2026 Returns)
FUTA Deadlines
Federal unemployment tax runs on its own schedule. The statutory rate is 6.0% on the first $7,000 of wages paid to each employee during the calendar year.13Office of the Law Revision Counsel. 26 USC 3301 – Rate of Tax14Office of the Law Revision Counsel. 26 U.S. Code 3306 – Definitions Employers who pay state unemployment taxes on time and in full generally receive a 5.4% credit, lowering the effective rate to 0.6%.15Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide
FUTA deposits follow a quarterly accumulation rule. If cumulative FUTA liability is $500 or less at the end of a quarter, carry it into the next quarter. Once it crosses $500, deposit the full amount by the last day of the month following the end of that quarter. Annual reporting happens on Form 940, due January 31 of the following year.16Internal Revenue Service. Instructions for Form 940 (2025)
Employers in FUTA credit reduction states owe extra FUTA. The Department of Labor announces those states after November 10 each year, and the additional tax is treated as a fourth-quarter liability due with Form 940 by January 31.17Internal Revenue Service. FUTA Credit Reduction
Personal Liability for Unpaid Trust Fund Taxes
Withheld income tax and the employee share of Social Security and Medicare are held in trust for the government; they are not the business’s money.18Internal Revenue Service. 5.17.7 Liability of Third Parties for Unpaid Employment Taxes When those funds aren’t turned over, the IRS can assess the Trust Fund Recovery Penalty against individuals.
The penalty equals 100% of the unpaid trust fund taxes, assessed personally.19Office of the Law Revision Counsel. 26 U.S. Code 6672 – Failure to Collect and Pay Over Tax, or Attempt to Evade or Defeat Tax It reaches anyone the IRS considers a “responsible person” who acted “willfully.” Responsible persons include owners, officers, directors, partners, LLC members, and even non-owner employees with real authority over which bills the company pays.20Internal Revenue Service. Establishing Responsibility and Willfulness for the Trust Fund Recovery Penalty (TFRP) Willfulness does not require intent to cheat. Paying other bills while knowing payroll taxes are due meets the standard.18Internal Revenue Service. 5.17.7 Liability of Third Parties for Unpaid Employment Taxes
Fixing Mistakes on a Filed Return
Errors on a filed Form 941 are corrected with Form 941-X. The window depends on the direction of the error:21IRS. Instructions for Form 941-X (Rev. April 2025)
- Overreported taxes: file within three years of the date the original Form 941 was filed, or two years from the date the tax was paid, whichever is later.
- Underreported taxes: file within three years of the date the original Form 941 was filed.
For underreported taxes, you generally avoid interest if you file the 941-X and pay the balance by the due date of the return for the quarter in which the error was discovered. Discover the mistake in May, file and pay by July 31.21IRS. Instructions for Form 941-X (Rev. April 2025)
Keep all employment tax records for at least four years after the fourth-quarter return for the year is filed.22Internal Revenue Service. Employment Tax Recordkeeping
A Note on State Payroll Taxes
The deadlines above are federal. Every state with an unemployment insurance program imposes its own tax, and many states plus some localities require income tax withholding on their own schedules. Some mirror the federal deposit calendar and some don’t. Getting the federal side right doesn’t shield you from a separate state penalty on the same payroll, so confirm the schedules with your state revenue or labor agency.
