Missing a payroll tax deposit is one of those things that sounds like a minor administrative slip, until you get the penalty notice. The IRS doesn't grade on a curve when it comes to employment taxes, and the penalties for missing or underpaying deposits are aggressive by design. The agency treats payroll taxes as money held in trust: it's not yours to miss with.
What Payroll Tax Deposits Actually Are
Every time you run payroll, two things happen. Your employees get paid, and the federal government expects its share to be set aside. That share includes federal income tax withheld from employee paychecks, plus both the employee and employer halves of Social Security and Medicare taxes (FICA). These amounts must be deposited, typically to the IRS via EFTPS, on a schedule determined by the size of your payroll.
Small businesses generally deposit monthly. Larger businesses deposit semi-weekly. New businesses start as monthly depositors. The schedule can change each year based on your prior year payroll volume, so many businesses get caught off guard by a mid-year reclassification.
The IRS collected over $5.7 billion in payroll tax penalties from businesses in 2024. Most penalties were assessed not for fraud, but for late or missed deposits, often from companies that simply didn't know the deadline.
The Penalty Cascade
When you miss a deposit or pay late, the IRS's Failure to Deposit penalty kicks in immediately. The penalty is a percentage of the unpaid amount, and it escalates based on how late you are:
1–5 days late: 2% penalty. 6–15 days late: 5% penalty. 16 or more days late: 10% penalty. More than 10 days after the IRS first notices: 15% penalty. These percentages compound on top of each other when deposits are consistently missed. Add in interest charges on any unpaid balance, and a few months of missed deposits can turn a $5,000 problem into a $7,000 or $8,000 one before you realize anything is wrong.
A single missed deposit at 10 days late costs 5%. Two months of misses can exceed 30% in combined penalties.
The Trust Fund Recovery Penalty
There's a worse version. If the IRS determines that payroll taxes were withheld from employees but not deposited, meaning the money was collected but not remitted, they can assess the Trust Fund Recovery Penalty (TFRP). This is assessed personally against the people 'responsible' for collecting and paying the taxes: often the business owner, the CFO, or anyone with check-signing authority.
The TFRP equals 100% of the unpaid trust fund portion. It's not dischargeable in bankruptcy. It follows you personally, not just the business. Business owners who thought they could restructure around payroll tax debt have found it isn't possible.
"We missed three deposits during a slow quarter. By the time we caught it, we owed almost $14,000 in penalties on a $40,000 payroll liability. We didn't know automated deposits were even an option."
How to Never Miss a Deposit
The single most reliable way to avoid payroll tax deposit failures is automation. When deposits are scheduled and executed automatically with every payroll run, there is no calendar to track, no wire transfer to remember, no deadline to miss. The money moves when payroll is processed.
OneCo calculates, withholds, and deposits federal and state payroll taxes automatically, every time you run payroll, for every employee. You're never manually calculating FICA. You're never logging into EFTPS separately. You're never guessing whether this pay period triggers a different deposit schedule.
Set up your payroll system before your first hire, not after. Retroactive corrections to payroll tax errors are expensive and time-consuming.
What to Do If You've Already Missed One
If you've missed a deposit, the best thing you can do is deposit immediately. The penalty percentage is lower the sooner you act. Contact the IRS or a payroll tax specialist before the notice period ends, you may be eligible for penalty abatement if this is your first offense and you have a clean compliance history.
Do not ignore IRS notices. The debt does not go away, and interest continues to compound. If you're behind on multiple payroll periods, a payment plan (installment agreement) is usually available, but you need to be current going forward while the past-due amounts are resolved.
