Employers must file quarterly Form 941s with the IRS to report wages, tips, and other compensation paid to employees, along with tax withholdings. At year-end, employers distribute Form W-2 to employees and the Social Security Administration (SSA), summarizing the total wages and withholdings for the year.
These forms must align—the information reported on Form 941 should match the data on each employee's W-2 to ensure accurate payroll tax reporting.
This guide explains how Form 941 and Form W-2 interact, highlights common pitfalls, and shares tips to help you stay compliant throughout the year.

What Form 941 Does vs. What Form W-2 Does
- Form 941: Filed quarterly, this form reports wages paid, tips received, federal income taxes withheld, and both the employer’s and employee’s portions of Social Security and Medicare taxes.
- Form 941 Deadlines: April 30, July 31, October 31, and January 31 (following each quarter). For Q4 2025, the deadline is February 2, 2026 (since January 31 is a Saturday).
- Form W-2: Filed annually, this form reports each employee’s total annual wages, withholdings, and benefits to both employees and the Social Security Administration (SSA).
- Form W-2 Deadline: Must be furnished to employees and filed with the SSA by January 31 following the close of the tax year. For tax year 2025, the deadline is February 2, 2026, since January 31 is a Saturday. For the latest updates, see our guide to 2025 W-2 changes.
Together, Forms 941 and W-2 provide a comprehensive record of payroll activity. Form 941 gives the IRS a quarterly overview of employment taxes, while the W-2 serves as a year-end summary of each employee’s earnings and withholdings.
The cumulative totals from the four quarterly filed 941 forms, including any corrections, must match the total of all W-2s issued under the same Employer Identification Number (EIN). Since Form 941 deadlines fall before W-2 deadlines, waiting until year-end to reconcile can make it difficult to fix errors. Performing quarterly reviews helps ensure a smoother W-2 process.

Reconciling Forms 941 and W-2
Employers are responsible for ensuring the information reported on Form 941 matches what appears on each employee's W-2. This includes cumulative wage, tip, and tax totals, as well as names, Social Security numbers, and other identifiers.
Key items that must match across Forms 941 and W-2 include:
- Total wages, tips, and compensation reported.
- Federal income tax withheld.
- Social Security wages and tips.
- Medicare wages and tips.
- Employee Social Security numbers and names.
Even minor discrepancies can trigger IRS inquiries or lead to tax issues for employees.
Common 941 vs. W-2 Mistakes
Mistakes are fixable, but it’s best to invest time upfront to submit everything correctly. This helps you avoid the hassle and risks of correcting forms later.
When completing these forms, be mindful of common mistakes that can be costly or time-consuming to fix.
- Mismatched wage or tax totals — forgetting to carry forward adjustments.
- Missing adjustments — such as tips, third-party sick pay, or fringe benefits.
- Overlooking multi-state complexities — different wage bases and reporting rules across states.
If you find discrepancies, investigate and resolve them before distributing W-2s or filing your fourth quarter Form 941. Making corrections before forms are filed or distributed is much simpler. For prior quarter Form 941 corrections, act promptly to avoid triggering IRS notices.
Compliance Tips for Smooth Reconciliation
Maintaining alignment between your quarterly and annual payroll filings requires consistent attention to detail, organization, and proactive planning. To minimize errors and keep your payroll reporting on track, it’s important to put robust processes in place throughout the year—not just at year-end.
Below are practical strategies employers can use to streamline reconciliation and ensure compliance:
- Run quarterly audits: Review payroll records each quarter to catch and correct discrepancies early.
- Use payroll software to flag variances: Automation helps identify mismatches before they become bigger problems.
- Double-check elective deferrals and benefit codes: Ensure retirement plan contributions and benefits are reported accurately.
Proactive reconciliation builds trust with employees and the IRS, reduces the risk of costly W-2Cs, and simplifies year-end processing.
