Form 941 deposits and the failure-to-deposit penalty: schedules, Schedule B, designation and relief

Which deposit schedule you are on

Every employer that files Form 941 is either a monthly or a semiweekly schedule depositor for the whole calendar year, and the IRS decides which before the year begins. The test is the lookback period: the four quarters from July 1 to June 30 that end in the prior year. For 2026 that is July 1, 2024 through June 30, 2025. Publication 15 states the rule plainly: if you reported $50,000 or less of taxes for the lookback period, you are a monthly schedule depositor; if you reported more than $50,000, you are a semiweekly schedule depositor. The amount counted is the total tax on line 12 of each Form 941 as originally reported. Corrections on Form 941-X don't change it: Publication 15's example is an employer that reported $45,000, later found a $10,000 understatement, and stays monthly for 2026.

The label confuses people because it has nothing to do with how often you run payroll. Publication 15: “Your deposit schedule isn't determined by how often you pay your employees or make deposits.”

• New employers. For a Form 941 filer, the lookback quarters before the business started count as zero, so the first calendar year is always monthly (Form 943, 944 and 945 filers are monthly for the first two years).
• Former Form 944 filers. A 2026 Form 941 filer that filed Form 944 in 2024 or 2025 uses calendar year 2024 as its lookback period.
• The $100,000 rule overrides the schedule. “If you accumulate $100,000 or more in taxes on any day during a monthly or semiweekly deposit period”, the tax is due the next business day. A monthly depositor that hits $100,000 becomes a semiweekly depositor the next day, for the rest of that year and all of the next.
• Small quarters. If total tax for the current quarter or the prior quarter is under $2,500, and there was no $100,000 next-day obligation, the tax can be paid with a timely filed return instead of deposited.

Form 945 backup withholding is a separate pot. Publication 15 says not to combine deposits for Form 941 and Form 945 liabilities, and Form 945's lookback is the second preceding calendar year. The Form 945 side is covered in Form 945 deposits made to the wrong form or year.

When each deposit is due

Three details produce many of the penalties the IRS sees:

• Liabilities follow the pay date. Publication 15 says the rules turn on the dates wages are paid (cash basis), not on when the liabilities are accrued in your books.
• Quarter-end splits. If a semiweekly period holds paydays in two quarters, each quarter's liability needs its own deposit, even when both are due the same day.
• Only D.C. holidays count. For deposits, a legal holiday means a holiday in the District of Columbia; state holidays do not move the due date. IRM 20.1.4.7.3 explains that EFTPS is available around the clock, so the state-holiday rule in IRC 7503 has no application to deposits.

There is a small safety margin. Under the accuracy of deposits rule, no penalty applies to a shortfall that is no more than the greater of $100 or 2 percent of the amount due, if the shortfall is made up by the makeup date: the return due date for a monthly depositor, and for a semiweekly depositor the earlier of the first Wednesday or Friday on or after the 15th of the following month or the return due date.

How to deposit: EFT, EFTPS and same-day wire

All federal tax deposits must be made by electronic funds transfer: EFTPS, IRS Direct Pay or your IRS business tax account, or through a payroll provider, bank or other third party that deposits for you. A new employer that showed a federal tax obligation when it applied for its EIN is pre-enrolled in EFTPS. Each successful payment returns an EFT Trace Number, which Publication 15 says can be used as a receipt or to trace the payment. Keep every one.

Timing matters inside the day. Publication 15: “EFTPS accepts same day payments of $1 million or less if the payment is submitted before 3:00 p.m. Eastern time on a business day.” Larger payments must be submitted by 8:00 p.m. Eastern the day before the due date. If you miss the EFTPS window, the same-day wire option through the Federal Tax Collection Service can still make the deposit on time, but it has to be arranged with your bank ahead of time and the bank may charge a fee.

The penalty tiers under IRC 6656

IRC 6656(a) imposes the penalty on any failure to deposit on the prescribed date unless the failure is shown to be due to reasonable cause and not willful neglect. The IRS manual treats a deposit as correct only if it has three components: made on time, in the correct amount, and in the correct manner (IRM 20.1.4.7). The rates, from Publication 15 and IRM 20.1.4.7.1:

“Late deposit penalty amounts are determined using calendar days, starting from the due date of the liability.” The 15 percent rate is the 10 percent rate plus 5 percent; when that fourth tier applies, the IRS generates CP 294 and assesses the extra 5 percent on the unpaid tax (IRM 20.1.4.20).

The same IRC 6656 schedule applies to Form 943, 944 and 945 deposits; Publication 15 says its deposit penalty rules, though written for Form 941, also apply to those forms. So the penalty math in the Form 945 deposit penalty calculator, built for backup withholding deposits, is the same IRC 6656 math; for a Form 941 deposit, work out the due date from the Form 941 rules above before you use it.

How the IRS applies your deposits

Before 2002, the IRS applied each deposit to the oldest unpaid liability in the quarter. One missed deposit early in a quarter could then make every later deposit late, a result Rev. Proc. 2001-58 describes as multiple cascading penalties. Congress changed the default in IRC 6656(e)(1): a deposit is applied “to the most recent period or periods within the specified tax period to which the deposit relates, unless the person making such deposit designates a different period or periods”. The revenue procedure explains why: “The application of deposits to the most recently ended deposit period will, in some cases, prevent the cascading of penalties”.

Publication 15's example: an employer owes $1,000 on April 15 and $1,500 on May 15, misses April, and deposits $2,000 on May 15. The IRS applies $1,500 to May and $500 to April, so $500 of the April liability remains undeposited and is penalized at the tier for its lateness.

Designation. Most-recent-first is only the default. IRC 6656(e)(2) lets you choose a different application, but only during the 90-day period beginning on the date of a notice that an FTD penalty has been imposed for that period. Rev. Proc. 2001-58 says you may call the toll-free number on the penalty notice or write to the address on it, including a revised schedule of deposits, and the IRS will adjust the penalty and notify you in writing. The manual is strict about the window: “A request not received within 90 days of the 23C date of a notice containing an FTD penalty assessment cannot be considered per IRC 6656(e)(2).” IRM 20.1.4.26.3 adds that you may designate more than one deposit, and that if a re-designation would raise the penalty the IRS does not assess the increase unless you agree. A request letter you can adapt is in the deposit designation request template.

The averaged penalty and Schedule B

The IRS cannot see your payroll calendar. It sees your deposits, from the EFT system, and your record of federal tax liability: the monthly amounts on Form 941 line 16 for a monthly depositor, or Schedule B for a semiweekly depositor. The Schedule B instructions put it bluntly: “Don't use Schedule B to show federal tax deposits.” The schedule shows liabilities on the dates wages were paid, and the IRS compares those against the deposits.

When the liability record is missing, incomplete, blank or has negative amounts, or its total does not tie to the tax on line 12, the IRS averages. The Schedule B instructions warn: “If you're a semiweekly schedule depositor and you don't properly complete and file your Schedule B with Form 941, the IRS may propose an averaged FTD penalty.” Publication 15 puts the averaged penalty at 2 to 10 percent, for returns with tax of $2,500 or more. The averaging methods are in Exhibit 20.1.4-3 of the manual: for a semiweekly depositor with no acceptable schedule, the quarter's tax is divided by 12 and assigned to the first four Wednesdays of each month; for a monthly depositor, it is divided by 3 and assigned to each month. Real paydays rarely fall on those dates, so the averaged figure can be far from the true one.

The manual's tolerance for a schedule that does not tie to the return is redacted in the public IRM. Make the total match line 12 to the cent and never enter a negative number: IRM 20.1.4.18 says a negative entry invalidates the schedule even when the total matches.

Fixing it after the fact. If you were assessed an FTD penalty and made an error on Schedule B that does not change the quarter's total, the Schedule B instructions let you file an amended Schedule B, marked Amended at the top, at the address on the penalty notice, and “The IRS will refigure the penalty and notify you of any change in the penalty.” A monthly depositor whose line 16 was wrong can file a Schedule B with monthly totals only. A late Form 941-X that increases tax needs an amended Schedule B with it, or the IRS may assess an averaged penalty.

Relief: first-time depositors, AEP, reasonable cause and bank errors

First-time depositors. IRC 6656(c) lets the IRS waive the penalty on an inadvertent failure to deposit employment tax in the first quarter a person was required to deposit, or on the first deposit after a required change in deposit frequency, if the return was filed on time and the net worth limits for awards of costs under IRC 7430 are met. Publication 15 states those limits: for a business, net worth of no more than $7 million and no more than 500 employees. IRM 20.1.4.26.3 says the first-time depositor penalty for Forms 941, 943 and 944 is waived systemically, with CP 238 to tell you. The CP 238 page says: “We waived the federal tax deposit penalty because you're filing Form 941, 943 or 944 for the first time.” IRM 20.1.4.26.2 extends the frequency-change relief by administrative waiver to a full abatement of the penalty on the first deposit after a change in frequency, including a change caused by the $100,000 rule. IRC 6656(d) also allows abatement the first time a depositor inadvertently sends the deposit to the IRS instead of depositing it.

Automatic Exemption from Penalty (AEP). The IRS's administrative penalty relief page lists Form 941 among the returns eligible for AEP, starting with 2026 quarterly returns. If the prior 12 consecutive quarters were timely filed and paid, the IRS does not assess failure to file, failure to pay or failure to deposit penalties, and sends a letter explaining that the relief was applied. Business filers have two more conditions: the IRS must not have waived the FTD penalty four or more times in the prior 12 quarters, and “The failure to deposit penalty was not charged for Electronic Federal Tax Payment System (EFTPS) avoidance.” In other words, AEP does not cover the 10 percent penalty for paying outside EFT. Details are in automatic penalty relief (AEP); where AEP does not apply, the older order of relief is in First Time Abate and the relief order.

Reasonable cause. IRM 20.1.4.26 requires a statement that addresses each penalized liability: “If the dates or explanations don't correspond with the penalized tax liability amounts, the taxpayer hasn't established a valid reason to waive the penalty.” A generic letter about a hard year does not meet that test. For employers that could not get a bank account, IRM 20.1.4.26.1.1 describes a signed statement with proof of at least one attempt to open an account as grounds for relief from the non-EFT penalty.

Bank errors, and why payroll providers are different. If your bank received a timely instruction with funds available and delayed the transfer, the penalty for the delay can be removed when the bank takes responsibility; the IRS asks for Form 13287, Bank Payment Problem Identification, signed by a bank official (IRM 20.1.4.24.2). The Form 13287 bank error abatement kit walks through it. A payroll provider that took the money and deposited it late is not a bank: “The Internal Revenue Code does not authorize the IRS to charge a penalty against payroll processors.” The manual calls that a contract issue between you and the provider, and says the withdrawal from your account does not by itself constitute a tax deposit (IRM 20.1.4.24.1 and 20.1.4.24.3.1). Unpaid trust fund taxes can also lead to the trust fund recovery penalty against the people responsible; see the trust fund recovery penalty.

The notices and what each one wants

The CP 276 notices are educational: IRM 20.1.4.19 says employers who were never told a penalty had been waived kept making the same error. The CP 134B page describes a discrepancy between the deposits credited to your account and the amount on your return, so check each deposit's period, form and EIN against your trace numbers.
