IRS Form 941 Deposit Rules: Schedules, EFTPS, and Penalties

The IRS Form 941 deposit rules place every employer on either a monthly or a semi-weekly deposit schedule, decided by a one-year lookback at your reported employment tax liability. Two dollar thresholds override the schedule, all deposits must move electronically, and missing a deadline triggers penalties that climb from 2% to 15% and, in the worst case, reach the individuals responsible for payroll.

How the Lookback Period Sets Your Schedule

Your deposit schedule for a calendar year depends on the total employment tax liability you reported during the lookback period: the 12 months running from July 1 through June 30 of the second preceding year. For calendar year 2026, the IRS looks at the Forms 941 you filed from July 1, 2024, through June 30, 2025.¹

That number sorts you into one of two buckets, and the classification holds for the entire calendar year. If your lookback liability was $50,000 or less, you deposit monthly. If it exceeded $50,000, you deposit semi-weekly. Brand-new employers have a lookback liability of zero by default, so they start as monthly depositors.²

Monthly Depositors

Monthly depositors send in all employment taxes accumulated during a calendar month by the 15th of the following month. January withholding is due February 15, February withholding is due March 15, and so on. If the 15th falls on a weekend or legal holiday, the deadline moves to the next business day.³

Semi-Weekly Depositors

Semi-weekly timing follows your payday, not the calendar. Taxes on wages paid Wednesday, Thursday, or Friday are due the following Wednesday. Taxes on wages paid Saturday through Tuesday are due the following Friday.³

The label is misleading. You’re not depositing twice a week by rule; you’re operating on a shorter leash than monthly filers, with the due date pegged to when you ran payroll. Semi-weekly depositors are guaranteed at least three business days after the close of a deposit period to make the deposit. When a legal holiday falls within those three days, you get one extra day per holiday.⁴

Two Thresholds That Override Your Schedule

$100,000 Next-Day Deposit

If you accumulate $100,000 or more in employment tax liability on any single day, the full amount is due by the next business day, regardless of your normal schedule.³

The threshold does not carry over between deposit periods. If a semi-weekly depositor accumulates $95,000 on Tuesday (the last day of a Saturday-through-Tuesday period) and $10,000 on Wednesday, the $10,000 belongs to a new deposit period, so the next-day rule isn’t triggered. The $95,000 is due Friday and the $10,000 the following Wednesday.³

Triggering this rule has lasting effect. You become a semi-weekly depositor for the rest of the current year and all of the following year.⁵

$2,500 De Minimis

At the other end, if your total tax liability for the whole quarter is under $2,500, you don’t have to make deposits during the quarter at all. You can pay the full balance when you file Form 941. One condition: this exception is unavailable if you triggered the $100,000 next-day rule at any point in the quarter.⁵

All Deposits Go Through EFTPS

Federal tax deposits must move electronically through the Electronic Federal Tax Payment System. EFTPS is a free Treasury service, and the IRS does not accept paper deposit coupons.⁶

Enrollment requires your Employer Identification Number, business name and address, and bank account details. The system issues a PIN and internet password. For each deposit you select the tax type (941 for employment taxes), the tax period, and the exact amount, and you receive a confirmation number.

The scheduling detail that catches employers off guard: a deposit must be scheduled at least one calendar day before the due date, by 8:00 PM Eastern Time the day before. A deposit scheduled on the actual due date is late, even if the money transfers successfully that day. For a semi-weekly deposit due Wednesday, you need it scheduled by 8:00 PM ET Tuesday. Build that one-day buffer into your payroll calendar or you’ll see penalties on deposits that look on time.

The Shortfall Safe Harbor

You won’t be penalized for a deposit shortfall if both of these conditions are met:³

The shortfall doesn’t exceed the greater of $100 or 2% of the amount you were required to deposit.
You cover the shortfall by the applicable makeup date.

Monthly depositors must deposit the shortfall by the due date of the Form 941 for the quarter in which it occurred. Semi-weekly depositors must deposit it by the earlier of the first Wednesday or Friday on or after the 15th of the month following the shortfall, or the return due date for that period.⁴

The safe harbor is useful when final payroll adjustments arrive after you’ve already deposited. Consistent shortfalls above 2% point to a process problem rather than rounding.

Penalties for Late Deposits

Late deposit penalties are a percentage of the underpaid amount, and they scale with how late you are:⁷

1 to 5 days late: 2%
6 to 15 days late: 5%
More than 15 days late: 10%
More than 10 days after the first IRS delinquency notice: 15%

The jump to 15% applies after you’ve ignored both the original deadline and the IRS’s follow-up notice. The IRS can waive these penalties for reasonable cause, such as a natural disaster or serious illness that prevented compliance. Not knowing the rules and cash flow problems don’t qualify.

The Trust Fund Recovery Penalty

The harshest consequence reaches past the business itself. Withheld income tax and the employee share of Social Security and Medicare are “trust fund” taxes because the employer holds them in trust for the government. When a responsible person willfully fails to deposit these amounts, the IRS can assess a penalty equal to 100% of the unpaid trust fund taxes against that individual personally.⁸

A “responsible person” is anyone with authority to decide which creditors get paid: officers, directors, bookkeepers, and payroll managers with check-signing authority. The penalty can be assessed against several people at once. “Willful,” in this setting, means the person knowingly used payroll tax money to pay other business expenses instead of sending it to the IRS, and the penalty is rarely waived.⁹

Deposit rules are a separate obligation from filing Form 941 itself. Depositing every dollar on time doesn’t excuse filing the quarterly return, and filing the return doesn’t substitute for the deposits.
