Failure-to-Deposit Penalty Under IRC § 6656: Tiers, Surcharge, and Abatement

The failure-to-deposit penalty under IRC § 6656 is a tiered charge on federal tax deposits that are late, short, or made the wrong way. It starts at 2% of the shortfall when a deposit is up to five days late and climbs to 15% once the IRS has issued a demand and the balance still sits unpaid. It applies to any tax that must be deposited electronically, most commonly the withheld income, Social Security, and Medicare taxes that employers hold in trust for the Treasury.

The Penalty Rate Tiers

IRC § 6656(a) sets the penalty as a percentage of the underpayment, meaning the difference between what you had to deposit and what you actually deposited on time. The rate rises the longer the money stays out:¹

1 to 5 days late: 2% of the underpayment
6 to 15 days late: 5% of the underpayment
More than 15 days late: 10% of the underpayment
Still unpaid more than 10 days after the first IRS delinquency notice or a demand for immediate payment: 15% of the underpayment

The tiers don’t stack. A deposit that lands 20 days late is charged at 10%, not the sum of the earlier tiers. The percentage runs only against the shortfall, so if you owed $10,000 and deposited $8,000 on time, the penalty attaches to the $2,000 you missed.¹

What Deposits Are Covered

The rule reaches federal income tax withheld from wages, both halves of Social Security and Medicare, and certain federal excise taxes. Withheld employment taxes are trust fund taxes: the money legally belongs to the government from the moment it is deducted from a paycheck, and the IRS treats late handling of it more aggressively than most other compliance failures.

That trust framing carries personal exposure. Under IRC § 6672, anyone responsible for collecting and paying over these taxes who willfully fails to do so can be assessed a separate Trust Fund Recovery Penalty equal to the full amount of the unpaid tax. “Responsible person” is read broadly and can reach officers, directors, bookkeepers, or anyone with authority over company finances. The only statutory carve-out protects unpaid, honorary board members of tax-exempt organizations who have no involvement in day-to-day financial operations and no knowledge of the failure.²

One boundary worth being clear about: outsourcing payroll does not shift the penalty. If a third-party processor deposits late, the IRS still penalizes the employer. Any dispute with the processor is a private contract matter between you and the vendor.

The 10% Electronic Deposit Surcharge

Since January 1, 2011, federal tax deposits must be made electronically. IRC § 6302(h) gives Treasury the authority to require it, and electronic transfer is now the only authorized method.³ Deposits can be made through your IRS business tax account, IRS Direct Pay for businesses, or the Electronic Federal Tax Payment System (EFTPS).⁴

Send a paper check or use any other non-electronic method and the IRS applies a 10% penalty on the amount, even if the funds arrive on time. This is sometimes called the “avoidance portion” of the failure-to-deposit penalty.⁵ Timing runs down to the hour too. To count as on time through EFTPS, the deposit has to be scheduled by 8 p.m. Eastern the day before the due date. Miss that window and the only same-day option is the Federal Tax Collection Service, a same-day wire processed through your bank.⁶

Interest Runs on Top

The penalty is not the whole cost. The IRS also charges interest on the unpaid tax, compounded daily, starting from the original due date. The rate resets quarterly at the federal short-term rate plus three percentage points. For the first quarter of 2026, that rate is 7%; for the second quarter, it drops to 6%.⁷

C corporations with underpayments over $100,000 pay a steeper rate: short-term plus five points, which is 9% in Q1 2026 and 8% in Q2. Interest runs separately from the penalty, so a late deposit generates both charges at the same time.

How the IRS Applies Partial Deposits

When your deposits don’t fully cover what you owe, the allocation matters. Under IRC § 6656(e), the default rule applies each deposit to the most recent liability period first within the tax return period. Which periods end up covered and which stay short directly changes the penalty.¹

You can ask for a different application of deposits if it would reduce your total penalty. A common approach is a first-in, first-out request that applies deposits to the oldest liabilities first, but whether FIFO or some other allocation saves you the most depends on the specific pattern of deposits and shortfalls. The deadline is firm: the request must be made within 90 days of the notice assessing the penalty. Miss the window and the default stands.¹

Getting the Penalty Removed

The statute has an escape valve. No penalty applies if you can show the failure was due to reasonable cause and not willful neglect.¹ The IRS decides reasonable cause case by case and puts the burden of proof on you. Natural disasters and serious illness can qualify. An inability to obtain banking services can support relief from the electronic-deposit portion of the penalty if you can document the effort to open an account.⁵ Blaming a payroll processor will not work; the IRS treats that as a private contract dispute.

First Time Abate

The IRS also offers an administrative waiver called First Time Abate that can remove a failure-to-deposit penalty if you have a clean three-year record. To qualify, you must have filed the same type of return for the three tax periods before the penalized period, and none of those prior returns can carry unreversed penalties other than estimated tax penalties.⁸ For business accounts, First Time Abate is also denied when four or more deposit penalty waivers appear in the three-year penalty history. No special form is required; you can request it by calling the IRS or responding to the penalty notice.

First-Time Depositor and Misdirected Deposit Waivers

IRC § 6656(c) gives the IRS discretion to waive the penalty for first-time employment tax depositors who make an inadvertent mistake, provided the return was filed on time. The same exception covers employers changing deposit frequency for the first time. Under § 6656(d), the IRS can abate the penalty the first time a depositor accidentally sends the payment directly to the IRS instead of the correct government depository.¹

How to File the Request

Start with the instructions on the notice. Many disputes get resolved with a phone call. For a formal written request, use Form 843, Claim for Refund and Request for Abatement. On the form you identify the tax period, the penalty amount, the IRC section cited on your notice, and a detailed explanation of why reasonable cause applies. Attach supporting documentation such as hospital records, bank correspondence, or disaster declarations.⁹

To claim a refund of a penalty already paid, you generally have three years from the date you filed the return or two years from the date you paid the penalty, whichever is later. File a separate Form 843 for each tax period.⁹
