Employers and other depositors who miss a federal tax deposit, deposit late, or deposit the wrong way face the failure-to-deposit penalty under IRC 6656. It is tiered by how late the deposit was, and it can arrive on top of the tax itself and the failure-to-pay penalty.

It is also one of the penalties with the most built-in relief. Some of that relief is statutory, some administrative, and one of the most useful pieces has nothing to do with excuses at all.

How the penalty is structured

IRC 6656(a) imposes a penalty equal to an applicable percentage of the underpayment, unless the failure is due to reasonable cause and not willful neglect. Under section 6656(b)(1), the percentage is 2 percent if the failure lasts no more than 5 days, 5 percent for more than 5 but not more than 15 days, and 10 percent for more than 15 days. It rises to 15 percent if the tax is not deposited within 10 days after the first delinquency notice or by the date of certain demands for immediate payment.

Two things follow. Every deposit is its own question, and how the IRS applies your deposits to your liabilities changes which liabilities look late.

Relief one: designate your deposits

IRC 6656(e)(1) says a deposit is applied to the most recent period or periods within the tax period to which it relates, unless the person making the deposit designates a different period. Under section 6656(e)(2), the designation can be made only during the 90-day period beginning on the date of a notice that the penalty has been imposed for that tax period.

Why this matters: when a business falls behind and catches up, the default rule can apply a catch-up deposit to the newest liability and leave older ones looking unpaid, which can push them into higher tiers. A designation lets you direct deposits to the liabilities that minimize the penalty.

The IRM describes the process. IRM 20.1.4 says the designation rule applies to deposits required after January 18, 1999, for Forms 720, 940, 941, 943, 944, 945 and 1042, and cites Rev. Proc. 2001-58. A taxpayer may designate more than one deposit, and may designate a first-in, first-out computation in writing or orally. If a requested designation would produce a higher penalty, the manual tells employees to explain that and offer to keep the lower amount. If the request is not received within 90 days of the notice date, the manual says the designation cannot be considered.

This is the most overlooked deposit penalty relief there is. It requires no reason at all, just a timely request and an accurate schedule.

Relief two: first-time depositors and frequency changes

IRC 6656(c) lets the IRS waive the penalty on an inadvertent failure to deposit employment tax if the person meets the net worth requirements referenced in section 7430(c)(4)(A)(ii), the return was filed on time, and the failure occurred during the first quarter the person was required to deposit employment tax, or on the first deposit after a required change in deposit frequency.

The IRM describes how this is administered. The penalty for first-time depositors of employment taxes on Forms 941, 943 and 944 is systemically waived, and the IRS sends a CP 238 educational notice explaining that no penalty was charged. The manual also says an administrative decision extended the frequency-change rule to allow full abatement when a penalty is assessed on the first deposit after a change, such as monthly to semiweekly, including a change caused by the $100,000 one-day rule.

And IRC 6656(d) lets the IRS abate the penalty the first time a depositor is required to deposit, if the deposit was inadvertently sent to the IRS instead of the authorized depository.

Relief three: first-time abatement

The deposit penalty under IRC 6656 is one of the three penalties covered by first-time abatement under IRM 20.1.1.3.3.2.1. Business taxpayers face two added conditions: the IRS cannot have waived the deposit penalty four or more times in the prior three years, and the penalty cannot have been charged for EFTPS avoidance. The manual adds that if some deposits were made through EFTPS as required but not all, the portion of the penalty not attributable to EFTPS avoidance can still be removed.

Remember the single-period rule. The manual's example is an employer with deposit penalties in all four quarters of a year after three clean years: FTA applies only to the first quarter, and the other three need reasonable cause.

For 2026 quarters and later, the IRS says its new Automatic Exemption from Penalty applies to Forms 940, 941, 943, 944 and 945, so qualifying employers should not be assessed the deposit penalty at all.

Relief four: reasonable cause

The statute itself excuses failures due to reasonable cause and not willful neglect. The general standard is the one in IRM 20.1.1.3.2: ordinary business care and prudence, with the same categories of serious illness, disaster, records and so on, applied to the person responsible for making deposits.

Two cautions specific to deposits. First, the manual's guidance on death or illness applies to a business only if the affected person had sole authority to make the deposit, and the IRS will ask whether having only one such person was itself prudent. Second, the IRM says that if payroll was met, the taxes were withheld and should have been available for deposit; employers hold withheld taxes in trust. A cash crunch rarely excuses a missed deposit of withheld taxes. See failure-to-pay relief and undue hardship for why.

A hypothetical catch-up

Picture a hypothetical semiweekly depositor that missed two deposits in a quarter during a bank account changeover, then made one large deposit two weeks later to catch up. Under the default rule in IRC 6656(e)(1), that catch-up deposit is applied to the most recent liabilities in the period. The two missed liabilities stay open longer, and the penalty for them climbs toward the higher tiers.

A timely designation lets the employer direct the catch-up deposit to the oldest liabilities first, which can shorten how long each one was late and move them into lower tiers. Nothing about the employer's conduct changes. Only the application of money it actually paid. That is why the 90-day window matters so much.

Read the notice carefully

Deposit penalty notices show how the IRS applied your deposits and computed each tier. Compare them to your bank records and your record of federal tax liability. Errors in the reported liability schedule, a deposit credited to the wrong period, or a deposit that never posted are corrections, not relief requests. Under IRM 20.1.1.3, the account is supposed to be corrected before any relief is considered, and system-computed penalties adjust when the corrections post.

The order to work it

  • Check the notice date and calendar 90 days for a designation request.
  • Rebuild the deposit schedule and test whether a designation or first-in, first-out application lowers the penalty.
  • Check whether the first-time depositor, frequency-change or misdirected-deposit rules apply.
  • Check first-time abatement for the earliest penalized quarter.
  • Make a reasonable cause request for anything left, with dates and documents.

Deposit penalties reward precision. Most of the relief is in the schedule, and the schedule has a deadline. Keep your payroll records, deposit confirmations and liability schedules organized by period, so that when a notice arrives you can rebuild the picture within the 90 days rather than discovering the window has closed.
