Payroll deposits are graded on a curve that steepens fast — 2% to 15% of each deposit. Here's the tier math, the cascade trap, and the deposit-designation move most employers never use.
IRC 6656 grades each late payroll deposit by how late it was: 2% within five days, 5% within fifteen, 10% beyond that, 15% after a demand notice goes unanswered. A single semiweekly deposit that slips a week costs 5% of the whole deposit — which is why the penalty shows up on CP161/CP210 notices in amounts that startle owners who were "only a few days behind."
Late because the schedule changed? Lookback-period shifts from monthly to semiweekly catch growing employers constantly — verify which schedule the current quarter requires.
Deposits scheduled in advance don't miss; same-day wires exist for the near-misses.
Within 90 days, direct payments to the newest liability to stop the cascade.
FTA for a clean account; reasonable cause (bank failure, disaster, provider collapse) with documentation otherwise.
Every notice page explains the deadline and drafts the response letter free — find yours.
Look up your IRS notice →By lateness tiers on each deposit: 2% (1–5 days late), 5% (6–15 days), 10% (more than 15 days), and 15% if still unpaid ten days after the IRS demands it. It applies to payroll deposit schedules — monthly or semiweekly — not to the quarterly 941 filing itself.
Yes — within 90 days of a penalty notice you can designate how deposits apply, which often shrinks cascading penalties (by default the IRS applies deposits to the oldest liability first, letting one missed deposit ripple forward).
Yes — failure to deposit is one of the three FTA-eligible penalties (with failure to file and failure to pay). A clean 3-year history on the 941 account gets one quarter's penalty removed on request.
Different animal entirely: FTD penalizes the business for late deposits; the TFRP makes individuals personally liable for withheld taxes that never arrived at all. If withholdings are being spent instead of deposited, that's the page to read next.
