The Cost of Mistakes: W-2 Penalties Employers Should Know

Filing Form W-2 might seem like just another step in the year-end payroll process, but getting it wrong can lead to serious consequences. From late submissions to simple data entry errors, IRS W-2 penalties can add up quickly—especially for businesses filing multiple forms. Understanding what triggers these penalties and how to avoid them is key to staying compliant and protecting your bottom line.
Every employer who pays wages subject to income tax, Social Security, or Medicare must file Form W-2 for each employee. The form reports annual wages and the taxes withheld. Employers must submit it to the IRS and the Social Security Administration (SSA) and provide copies to employees by January 31st. Even small mistakes can lead to fines, delays, and headaches for both you and your employees.
Common W-2 Filing Mistakes
Even with the best intentions, errors on Form W-2 are more common than many employers realize. Unfortunately, the IRS doesn’t always show leniency—many of these mistakes can trigger penalties, even if they’re unintentional. So what are the most frequent W-2 filing errors?
- Missing the filing deadline: Employers must submit Form W-2 to the SSA and deliver copies to employees by January 31st. Late filings are one of the quickest ways to rack up penalties.
- Incorrect employee information: Typos in names, incorrect Social Security Numbers (SSNs), or mismatched personal details can cause issues with the SSA and result in fines.
- Wrong wage or tax amounts: Inaccurate reporting of wages, tips, or withheld taxes not only affects employee records but can also flag your business for an audit.
- Using the wrong tax year: Filing a W-2 with an outdated or future tax year can confuse both the IRS and your employees.
- Failing to e-file when required: As of recent IRS rules, if you’re filing 10 or more information returns (W-2s, 1099s, etc.), you must file electronically. Employers who mail paper forms instead of e-filing face penalties.
- Not providing copies to employees: Employers must furnish W-2s to employees by the same January 31st deadline. Failing to do so may result in additional fines per employee.
Penalties for Incorrect Filing

The IRS issues penalties based on how late the correct Form W-2 is filed, and the costs can escalate quickly. These penalties are charged per form, which means businesses with multiple employees can face significant fines if they aren’t careful. Here’s a breakdown of the current penalty structure (as of the 2025 tax year):
Filing Status | Penalty Per Form | Maximum Penalty (Large Business) | Maximum Penalty (Small Business) |
---|---|---|---|
Filed within 30 days of due date | $60 | $630,500 | $220,500 |
Filed more than 30 days late but by August 1st | $120 | $1,891,500 | $630,500 |
Filed after August 1st or not at all | $310 | $3,783,000 | $1,261,000 |
Intentional Disregard | $630 | No Limit | No Limit |
*It’s important to note that these penalties apply separately to forms filed with the SSA and copies provided to employees. That means one error can potentially result in double the penalty.*
Penalties for Incorrect Information
Filing on time is just one part of compliance—accuracy matters just as much. If the information reported on a W-2 is incorrect or incomplete, the IRS may issue penalties even if the form was filed by the deadline.
Common issues that can trigger these penalties include:
- Wrong employee name or SSN: These must match the Social Security Administration’s records exactly.
- Inaccurate wage or tax withholding amounts: Misreporting these figures can affect an employee’s tax filing and trigger IRS scrutiny.
- Missing fields: Leaving required boxes blank—like employer EIN, state wages, or tax codes—can lead to form rejections and fines.
Just like with late filings, incorrect forms are penalized per return:
- $60 to $310 per incorrect form, depending on how quickly the corrected version is filed.
- $630 per form for intentional disregard, with no annual cap.
And don’t forget: businesses are also required to provide accurate W2s to employees. Failing to do so by January 31st can lead to separate penalties—up to $310 per employee if not corrected promptly.
How to Avoid W-2 Penalties (Employer Checklist)

Avoiding W-2 penalties starts with building a reliable payroll process and staying proactive throughout the year. Here’s a quick checklist to protect your business:
✅ Verify employee names and SSNs with the Social Security Administration.
✅ Use reputable payroll or W-2 filing software with built-in error checks.
✅ File electronically if you have 10 or more returns.
✅ Review wages, tax withholding, and EINs before submitting.
✅ Furnish copies to employees by January 31st.
*Pro Tip: Filing on time is the simplest way to avoid IRS penalties. Even a small delay can result in significant costs.*

Form W-2 may be a routine part of year-end payroll, but it’s not one to take lightly. Mistakes—whether it’s filing late, entering incorrect information, or failing to send forms to employees—can lead to steep penalties that grow quickly with each form affected.
The good news? These penalties are entirely avoidable with the right tools, planning, and attention to detail. By verifying employee data, e-filing when required, and staying on top of deadlines, you can avoid IRS W-2 penalties altogether.
