Summary: Late payroll tax deposits trigger IRS penalties of 2 percent (1 to 5 days late), 5 percent (6 to 15 days), 10 percent (over 15 days), plus daily interest. Amounts not deposited within 10 days of an IRS notice jump to 15 percent. Officers and owners can be held personally liable for withheld taxes under the trust fund recovery penalty. States add their own penalties for late unemployment filings.
The IRS treats payroll taxes differently from every other business tax because most of the money is not yours: it is your employees' withholding that you hold in trust. That is why the penalties start fast, scale steeply, and can follow you personally. This guide covers the penalty schedule and the practices that keep you out of it.
Payroll tax deposits are due on a monthly or semiweekly schedule depending on your lookback-period liability, made electronically through EFTPS. Miss the deadline and the penalty tiers apply: 2 percent of the late deposit if it is 1 to 5 days late, 5 percent if 6 to 15 days late, and 10 percent if more than 15 days late. If the tax remains unpaid more than 10 days after the first IRS notice demanding payment, the penalty jumps to 15 percent. Interest accrues daily on the unpaid balance on top of the penalty.
A concrete example: a $12,000 monthly deposit paid 20 days late draws a 10 percent penalty, $1,200, plus about three weeks of interest. Paid 4 days late, the same deposit costs $240. The schedule is designed to reward fixing mistakes fast, so a late deposit discovered on day 3 should be made on day 3, not bundled with next month's.
The withheld portion of payroll taxes, employees' income tax withholding plus their half of Social Security and Medicare, is called trust fund tax because you hold it in trust for the government. If the business fails to remit it, the IRS can assess the trust fund recovery penalty against any responsible person who willfully failed to pay: owners, officers, check-signers, and sometimes bookkeepers or payroll managers. The penalty equals 100 percent of the unpaid trust fund tax, and it is personal: it survives the business closing.
Willful does not mean malicious. Paying other creditors, including the landlord and suppliers, while payroll taxes go unpaid counts as willful. Courts have applied the penalty to people who merely had the authority to pay and knew the taxes were owed. If cash is tight, payroll taxes get paid before anything except possibly payroll itself.
Separate from deposits, the quarterly Form 941 carries its own failure-to-file penalty: 5 percent of the unpaid tax per month, up to 25 percent, plus failure-to-pay penalties. Filing on time even when you cannot pay in full cuts the damage significantly. States run parallel systems for unemployment insurance and withholding, with their own late-filing and late-payment penalties, and late SUTA payments can cost you the federal FUTA credit worth 5.4 percent.
Four practices cover nearly all cases. First, use a payroll service or reputable payroll software that makes deposits and filings automatically; the monthly cost is trivial against one penalty. Second, keep payroll tax money in a separate account so it is never accidentally spent on operations. Third, calendar every deposit and filing deadline, including state quarterly filings, which have different due dates than federal. Fourth, if you do fall behind, file on time, pay what you can, and call the IRS: installment agreements stop the bleeding, while silence lets penalties compound.
The IRS failure-to-deposit penalty is 2 percent for 1 to 5 days late, 5 percent for 6 to 15 days late, 10 percent beyond 15 days, and 15 percent if unpaid 10 days after an IRS notice, plus daily interest.
Yes. The trust fund recovery penalty lets the IRS assess 100 percent of unpaid withheld taxes against responsible persons, including owners and officers, personally. It applies even if the business has closed.
File anyway. The failure-to-file penalty (5 percent per month, up to 25 percent) is much larger than the failure-to-pay penalty, and filing preserves your eligibility for installment agreements.
Yes. States impose their own penalties for late unemployment insurance and withholding filings and payments, and late SUTA payments can jeopardize the federal FUTA credit.
