TC 180: Failure to Deposit (FTD) Penalty Assessed

What the code actually does

TC 180 assesses the Failure to Deposit (FTD) penalty under IRC 6656 — a penalty for depositing employment or excise tax "in the correct amount, within the prescribed time period, and/or in the required manner" (per IRM 20.1.4.1.1) other than through the ordinary balance-due-with-the-return process. Per IRS Document 6209, Section 8A, TC 180 is "a manually assessed or generated from TC 150 input penalty for insufficient and/or untimely deposit of taxes (FTD)," applicable to Forms 720, 940, 941, 943, 945, 1042, and CT-1 — the employment- and excise-tax return family, not individual income tax. A separate code pair, TC 186/187, handles the purely computer-generated version of the same penalty with no manual input at all; TC 181, the abatement code, reverses "a previously assessed 180, 186 Deposit Penalty in whole or in part," so either origin gets abated the same way. This is a strict-liability penalty in the sense that it attaches to the timing and mechanics of the deposit, not to whether the tax itself was ever paid — a client who deposited the full amount three days late still triggers TC 180.

The rate tiers — and where the fifth one hides

The FTD penalty is not one flat rate. IRM 20.1.4.7.1(1) sets out a tiered structure by how late — or how the deposit was made: 2 percent for deposits 1–5 days late, 5 percent for deposits 6–15 days late, 10 percent for deposits made more than 15 days late, and a separate flat 10 percent "for required deposits not paid by EFT" — the electronic-funds-transfer requirement that, in current practice, means the Electronic Federal Tax Payment System (EFTPS) — regardless of how many days late that deposit actually was. The fifth tier is the one practitioners most often miss reviewing for: 15 percent — "a 5 percent addition to the 10 percent for late payment" — applies once an amount is "still unpaid more than 10 days after the date of the first notice requesting payment of the tax due or the day on which the taxpayer received notice and demand for immediate payment, whichever is earlier." In practice, that means a TC 180 balance a client sat on after the first IRS notice can escalate from 10 percent to 15 percent automatically, without any new missed deposit — worth checking against the transcript dates before assuming the assessed rate is simply wrong.

The abatement path: First-Time Abate names this penalty specifically

IRM 20.1.1.3.3.2.1 lists exactly three penalties eligible for First-Time Abate, and the FTD penalty under IRC 6656 is one of them, alongside Failure to File and Failure to Pay. The standard clean-history test applies: the taxpayer "filed the same return as the penalized return for the 3 years preceding the penalized tax period," with no unreversed penalties and no prior suppression coded with Penalty Reason Code 018, 020, or 021 on those years. Two BMF-only traps sit on top of that general test, and both are worth checking before telling a client FTA is off the table. First, FTA is unavailable if "a total of four or more FTD penalty waiver codes are present in the taxpayer's three-year penalty history" — a business that has already had four FTD penalties waived is treated as a repeat case, not a first-time one. Second, FTA does not reach the part of a penalty "charged for EFTPS avoidance" — the mandatory-EFT tier described above — but the IRM is explicit that this is a per-dollar carve-out, not an all-or-nothing bar: "if the taxpayer made some deposits electronically by EFTPS as required but not all and all other FTA criterion are met, any portion of an FTD penalty not attributable to EFTPS avoidance can be removed or suppressed." The Federal Tax Desk's Penalty Abatement Analyzer runs this same FTA test, cited to the same IRM section, against a client's actual compliance history.

The abatement path: reasonable cause, and the safe harbor that may mean no penalty was ever proper

If FTA is unavailable (a repeat FTD case, or the EFTPS-avoidance carve-out described above), reasonable cause under IRC 6656 is the route: the penalty does not apply if the taxpayer can show that the failure to deposit was due to reasonable cause and not willful neglect. IRM 20.1.1.3.2 frames the standard as "ordinary business care and prudence" and recognizes the same enumerated categories used across the Penalty Handbook — death or serious illness, fire or casualty, inability to obtain records, and reliance on erroneous IRS advice among them — with mere forgetfulness, a bookkeeping mistake or reliance on another party generally falling short on their own. Before building either case, though, check whether the penalty should have posted at all: IRM 20.1.4.8.7 provides that no penalty applies if a deposit shortfall "does not exceed the greater of $100 or 2 percent of the amount of taxes otherwise required to be deposited" and the shortfall is cured by the makeup date. For a monthly depositor, the makeup date is the due date of the return for that period. For a semi-weekly depositor, it is the earlier of that return due date or the first Wednesday or Friday on or after the 15th of the month following the month in which the deposit was due. The rule worth being able to say to a client without notes: under $100 or 2 percent, whichever is bigger, fixed by the makeup date, and no penalty was ever properly owed. A TC 186 computer-generated assessment in particular can miss this safe harbor if the system applied the shortfall payment to a different period than the client designated within the 90 days IRC 6656(e) allows after the penalty notice, so verify both where the IRS applied the payment and the client's deposit-frequency classification under the lookback rules in 20.1.4.8.2 through 20.1.4.8.4 (monthly at $50,000 or less of employment tax reported for the lookback period, semi-weekly above that) before conceding the assessment is correct; either check can support a full reversal, not merely a reduced one.

What people mistake TC 180 for

People confuse TC 180 with TC 160, the manually computed Failure to File penalty, because both get informally called a "late penalty" and both live on the same balance-due notice. They are not the same failure. TC 160/TC 161 penalize an untimely-filed return under IRC 6651(a)(1) — the return itself came in late — computed on the tax shown as due; TC 180/181 penalizes an untimely or short deposit under IRC 6656, which can happen on a return filed exactly on time. A business can owe both at once on the same Form 941 period — a late return plus late deposits within it — and each has its own rate structure and its own reasonable-cause case; conceding or resolving one says nothing about the other. TC 180 is also easy to conflate with TC 186, its computer-generated sibling — both post the identical penalty under the identical statute, so the distinction rarely changes the abatement strategy, but it does affect where to look for a data error. TC 180 can itself be either manually keyed or generated from TC 150 input, so a data-entry mistake is still on the table; TC 186 rules that out entirely, since it posts only from what the Master File (the IRS’s central account-processing system) computed on its own from the return and deposit records on file, with no manual step anywhere in its history.

The practitioner's actual next step

Pull the deposit schedule before pulling the penalty notice apart — confirm the client's actual depositor status (monthly or semi-weekly) for the period under the 20.1.4.8.2 lookback rule, since a misclassification is a data error that can eliminate the penalty rather than merely excuse it.

Check the safe harbor first: if the shortfall was under the greater of $100 or 2 percent and was cured by the makeup date, the correct outcome is a full TC 181 reversal on the facts, not a negotiated reasonable-cause abatement.

Run the Penalty Abatement Analyzer for the FTA eligibility check, then check the two BMF-specific traps above against the account, and read the list of tests the Analyzer runs on the return, before defaulting straight to a reasonable-cause narrative that takes more time to document and is a lower-probability approval.

File the abatement request on Form 843 or by responding directly to the notice, and separately confirm the assessed rate against the actual deposit and notice dates — a 15 percent assessment is only correct if ten days actually passed after the first notice or demand, not merely because the balance sat unpaid for a while.

The FTD penalty sits on the same module (the IRS’s record for one tax period within the account) as the underlying employment tax, but it has its own 10-year collection statute running from its own assessment date, not automatically the tax's — a TC 180 posted well after the original TC 150 (an audit-driven deposit adjustment, for instance) can carry a later CSED than the tax it rides with. Verify the current Collection Statute Expiration Date (CSED) with the CSED Calculator before assuming an old, unaddressed TC 180 balance is still collectible, or has already expired.

On a 2025 or later tax-year return or a 2026 or later quarterly return of a form listed in IRM Procedural Update SBSE-20-0626-0643, check for Automatic Exemption from Penalty (AEP) before you request relief: an unreversed TC 971 action code 996 on the return’s own module shows that the IRS already granted AEP or a prior First-Time Abate there, and the IRS grants AEP when, among other conditions, an unreversed action code 995 sits on each of the prior three years’ modules (12 consecutive quarters for quarterly returns) and the taxpayer filed the return within three years of its original due date, but not when an unreversed 996 sits on any of those modules.
