How to Prepare for a Payroll Audit
An IRS employment tax exam starts with deposit history: the failure-to-deposit penalty runs 2, 5, 10, or 15 percent depending on how late a deposit was, and the tiers replace rather than stack. Records carry separate retention windows across the IRS, DOL, USCIS, and ACA. BEG keeps that data inside your payroll system at $45 per employee monthly.
The notice arrives. Here is what gets checked first
An IRS employment tax exam does not start with a broad review of your books. It starts narrow: deposit history. Was every federal deposit made on time, and if not, how late? The failure-to-deposit penalty runs 2 percent for deposits 1 to 5 days late, 5 percent for 6 to 15 days, 10 percent for more than 15 days, and 15 percent once the IRS has sent a notice and the balance is still unpaid 10 days later. The tiers replace each other rather than stacking, but interest keeps running on the penalty itself. That single number, pulled from deposit records, sets the tone for everything that follows.
Four agencies, four different retention clocks
A payroll audit rarely comes from one agency asking one question. The retention window an auditor expects depends entirely on which agency is asking.
| Agency | What it wants | Retention window |
|---|---|---|
| IRS | EIN, wage amounts and dates, tips, SSNs, employment dates, sick pay, undeliverable W-2s | 4 years after filing the Q4 return |
| DOL | Payroll records, plus underlying time cards, rate tables, and schedules | 3 years payroll, 2 years underlying data |
| USCIS | Form I-9, produced on request | Standard I-9 retention; 3 business days to produce |
| IRS (ACA) | Forms 1094-C and 1095-C, or reconstructable data | 3 years from the filing due date |
Miss the distinction between these windows and a business can discard something the DOL still expects while correctly clearing the IRS retention period, or the reverse. Each clock runs on its own schedule.
The personal exposure: Trust Fund Recovery Penalty
Deposit failures do not stay a company-only problem. The Trust Fund Recovery Penalty equals the unpaid withheld income tax plus the employee share of FICA, and it can be assessed personally against any responsible person who willfully failed to pay it, not just against the business entity. The IRS sends a letter giving 60 days to appeal before that assessment becomes final, which is the window to get it right.
What BEG can produce the day a notice arrives
BEG keeps the 941, 940, state SUI, W-2, and deposit records inside the client's payroll system in the retention windows above, and can pull a deposit-and-filing history the same day an IRS or state notice arrives. Responding to the auditor, representing the client, reconciling the general ledger, and anything involving worker classification stay with the client's CPA or counsel; BEG supplies the record, not the defense.

Frequently Asked Questions
What does an IRS employment tax auditor check first?
Deposit history. The failure-to-deposit penalty runs 2 percent for deposits 1 to 5 days late, 5 percent for 6 to 15 days, 10 percent for more than 15 days, and 15 percent once a notice has gone out, and interest runs on top. The tiers replace each other rather than stacking.
How long does the IRS expect employment tax records to be kept?
At least 4 years after filing the fourth-quarter return for the year. That includes the EIN, wage payment amounts and dates, tips reported, fair market value of in-kind wages, employee names, addresses, and Social Security numbers, employment dates, sick-pay records, and undeliverable W-2 copies.
Does DOL use the same retention window as the IRS?
No. DOL requires FLSA payroll records for 3 years, while the underlying time cards, wage rate tables, schedules, and deduction records only need 2 years. Both must be open to WHD inspection at the workplace or a central records office.
How fast do I-9 records have to be produced in an audit?
Within 3 business days of an inspection request from DHS, the DOJ Immigrant and Employee Rights Section, or DOL. That is a much tighter production window than the IRS or DOL retention rules carry.
How long does ACA reporting data have to be kept?
Copies of filed Forms 1094-C and 1095-C, or the ability to reconstruct that data, for at least 3 years from the due date.
What is the Trust Fund Recovery Penalty?
A personal penalty equal to the unpaid withheld income tax plus the employee share of FICA, assessed against any responsible person who willfully failed to pay it. The IRS sends a pre-assessment letter that gives 60 days to appeal before the penalty is actually assessed.
Can the Trust Fund Recovery Penalty be assessed against an owner personally?
Yes. It attaches to whoever the IRS determines is a responsible person who acted willfully, which can include an owner, officer, or anyone with authority over which bills get paid, not just the company itself.
What can BEG pull the day an audit notice arrives?
BEG keeps the 941, 940, state SUI, W-2, and deposit records inside the client's payroll system in the retention windows above, and can produce a deposit-and-filing history the same day a notice arrives, all inside standard managed payroll at $45 per employee monthly.
Does BEG represent a client in front of the IRS or DOL?
No. Responding to the auditor, representing the client, reconciling the general ledger, and anything involving worker classification stay with the client’s CPA or counsel. BEG supplies the underlying payroll record they need to do that.
