The Failure-to-Deposit Penalty Tiers: 2%, 5%, 10% and 15% Under IRC 6656

Employers do not just owe payroll taxes. They owe them on a schedule, deposit by deposit, through the electronic system the Treasury designates. Miss the schedule and the failure-to-deposit penalty applies to each late or short deposit separately. It is not a monthly penalty. It is a one-time percentage, and the percentage depends on how many days late you were.

The four tiers

IRC 6656(a) imposes a penalty equal to the applicable percentage of the underpayment of a required deposit. IRC 6656(b)(1) sets the percentages, and IRM 20.1.4.7.1 says the days are counted as calendar days from the deposit due date.

The "underpayment" is defined in IRC 6656(b)(2) as the amount required to be deposited minus the amount deposited on or before the due date. Each deposit period is scored on its own shortfall.

Deposit due dates in brief

Most Form 941 filers are either monthly or semiweekly depositors, based on a lookback period. Monthly depositors deposit each month's liability by the 15th of the following month. Semiweekly depositors follow a Wednesday/Friday schedule. A $100,000 one-day rule accelerates very large liabilities to the next business day. IRM 20.1.4.8 covers each schedule. The examples below use a monthly depositor.

There is also a de minimis rule: an employer with a small quarterly liability can pay with the return instead of depositing. If you qualify, there is no deposit penalty to compute. Check the current Form 941 instructions for the threshold.

Worked example: one quarter, three mistakes

A monthly depositor has $12,000 of Form 941 liability in each month of the second quarter of 2026. Due dates: April liability by May 15, May by June 15, June by July 15.

The June amount fails twice: it is more than 15 days late, and it was paid with the return rather than deposited electronically. Both put it at 10 percent. The rates do not stack. The highest applicable tier controls.

The 15 percent tier

Say the employer in the example sends only $6,000 with the return on July 31 and leaves $6,000 unpaid. The IRS sends its first notice requesting payment on September 8, 2026. If the remaining $6,000 is still unpaid more than 10 days later, IRC 6656(b)(1)(B) raises the rate on that unpaid amount to 15 percent.

How deposits are applied: the most recent period rule

This is where payroll penalties used to cascade. IRC 6656(e)(1) says a deposit is applied to the most recent period or periods within the tax period to which the deposit relates, unless the depositor designates otherwise. IRM 20.1.4.7.4 and Rev. Proc. 2001-58 apply that rule to deposits for periods after December 31, 2001.

Why it matters: suppose the employer skips the April deposit entirely but makes the May deposit on June 15 and the June deposit on July 15, both on time. Under the most recent period rule, the June 15 deposit covers May and the July 15 deposit covers June. Only April is late.

The 90-day designation window

IRC 6656(e)(2) lets the depositor designate which period a deposit applies to, but only during the 90 days beginning on the date of a notice that the penalty has been imposed. In some fact patterns a designation can move dollars into the period where they reduce the penalty most. Calendar that 90-day window when the penalty notice arrives.

Waivers built into the statute

• Reasonable cause. IRC 6656(a) does not apply if the failure was due to reasonable cause and not willful neglect.
• First-time depositors. IRC 6656(c) lets the IRS waive the penalty for an inadvertent failure in the first quarter a person was required to deposit employment taxes, or on the first deposit after a change in deposit frequency, if the return was filed on time and the net worth requirements referenced in IRC 7430(c)(4)(A)(ii) are met.
• Deposit sent to the IRS by mistake. IRC 6656(d) lets the IRS abate the penalty the first time a required deposit is inadvertently sent to the IRS instead of the depository.

Interest on the deposit penalty

The failure-to-deposit penalty is an assessable addition that falls under the general rule of IRC 6601(e)(2)(A). Interest on it runs only if it is not paid within 21 calendar days of notice and demand (10 business days if $100,000 or more), and then only from the date of the notice. Interest on the underlying late tax is a separate charge from the deposit due date. See interest on penalties.

Deposit penalties and the trust fund penalty

Failure-to-deposit penalties sit on the business account. They are not part of the Trust Fund Recovery Penalty, which reaches only the withheld income tax and the employee share of FICA. If a business is falling behind on deposits, the bigger number to watch is the trust fund balance; see computing the TFRP and Payroll Tax Problems for Businesses.

Checking an FTD penalty notice

1. List each deposit liability by date from your Form 941 Part 2 or Schedule B.
2. List each deposit with its settlement date.
3. Apply deposits to the most recently ended deposit period, unless you designated otherwise.
4. Count calendar days late for each shortfall and apply the tier: 2%, 5%, or 10%. Use 10% for amounts not deposited electronically.
5. Apply 15% to any amount still unpaid more than 10 days after the first delinquency notice.

Worked example: a semiweekly depositor

Semiweekly depositors are graded deposit by deposit on a much tighter schedule. Under the deposit rules in IRM 20.1.4.8 and Publication 15, wages paid on Wednesday, Thursday, or Friday are generally deposited by the following Wednesday, and wages paid Saturday through Tuesday by the following Friday.

Say a semiweekly depositor pays wages on Friday, August 7, 2026, creating an $8,000 liability due Wednesday, August 12. If the deposit settles Monday, August 17, it is five calendar days late, and the penalty is 2 percent, or $160. If it settles Tuesday, August 18, it is six days late, and the penalty is 5 percent, or $400. One day costs $240. For a business with weekly payrolls, those single days add up fast across a quarter.

A failure-to-deposit penalty billed by notice draws interest only if it is not paid within 21 days of notice and demand. Using the $2,040 quarter from the first example, a notice dated September 8, 2026 paid on October 20, 2026 draws interest from September 8 because the 21-day window closed September 29. At 7 percent compounded daily that is $16.50. Paid by September 29, the interest would have been zero.

Averaged penalties when the schedule is missing

The deposit penalty is computed against the liability schedule the employer reports, either on Form 941 Part 2 for monthly depositors or on Schedule B for semiweekly depositors. IRM 20.1.4.8.8 says that if that record of liability is incomplete, blank, or negative, the IRS averages the total tax over the period. An averaged penalty can be higher than one computed from the real payroll dates, because it may treat liabilities as arising earlier than they did. If you receive an averaged penalty, filing a corrected liability schedule is often the first step to recomputing it.

The tiers also explain why partial deposits are worth making. Each shortfall is scored separately, so depositing $6,000 of an $8,000 liability on time leaves only $2,000 exposed to the late tiers. A partial deposit never makes the penalty larger, and it usually makes it much smaller.

The bottom line

The deposit penalty rewards speed. A deposit five days late costs 2 percent; the same deposit sixteen days late costs five times as much. If you are short, deposit what you have on time and the rest as soon as possible, and never let a delinquency notice sit for ten days. If a quarter went sideways, have someone rerun the allocation before you pay the bill.
