Who Is Responsible for an Incorrect W2?

Navigate W2 inaccuracies. Learn who is responsible for errors, how to get them corrected, and why accurate tax documentation is crucial.

A W2 form, officially known as the Wage and Tax Statement, is a document employers issue annually, detailing an employee’s wages and withheld taxes (federal, state, local, Social Security, and Medicare). Employees use it to file tax returns, and it reports FICA taxes to the Social Security Administration for future benefit calculations. Errors on W2 forms can occur, and understanding responsibility for inaccuracies is important for resolution. An incorrect W2 can complicate tax filing, affecting tax liability or future Social Security earnings. Addressing these discrepancies ensures compliance and accurate financial records.

Understanding Common W2 Errors

Errors can appear on a W2 form, each carrying different implications. Common issues include incorrect personal information like a misspelled name or inaccurate Social Security Number (SSN), which can hinder IRS data verification and lead to processing delays.

Wage amounts in Box 1 (Wages, tips, other compensation), Box 3 (Social Security wages), or Box 5 (Medicare wages and tips) might be inaccurate due to miscalculations of gross pay or bonuses, directly affecting reported and taxable income.

Incorrect federal income tax withheld (Box 2), Social Security tax (Box 4), or Medicare tax (Box 6) can also be present. These errors impact the amount of tax an employee is credited for, potentially leading to underpayment or overpayment.

An employer’s Employer Identification Number (EIN) or address might also be incorrect, causing federal reporting issues. Other errors can extend to benefits, retirement plan contributions, or dependent care assistance, affecting deductions and credits.

Determining Accountability for W2 Errors

The primary responsibility for accurate W2 forms lies with the employer. Employers are legally mandated to provide employees and the Social Security Administration (SSA) with correct W2 forms by January 31 each year.

This obligation, outlined in IRS Section 6051, ensures employers report accurate annual earnings and tax withholdings.

Errors frequently arise from internal payroll processes, such as data entry mistakes or miscalculations. Issues can also stem from third-party payroll providers, but the employer remains accountable for the information.

The employer retains ultimate responsibility for the W2’s accuracy.

While the employer holds primary duty for W2 accuracy, an employee’s actions can sometimes contribute to an error. For instance, incorrect personal information like a wrong Social Security Number or outdated address can lead to discrepancies.

Employers are still expected to verify employee information and correct errors upon discovery, distributing a corrected W2 form (Form W-2c) to both the employee and the SSA.

Steps to Correct an Incorrect W2

If an incorrect W2 form is discovered, taking action is important. The initial step involves contacting the employer’s payroll or human resources department to report the error. The employee should explain the discrepancy and request a corrected W2.

When reporting, employees should provide specific details, such as the exact box or amount that is incorrect, and offer supporting documentation like pay stubs. The employer is then responsible for issuing a corrected W2, known as Form W-2c, or Corrected Wage and Tax Statement.

If the employer is unresponsive or unwilling to issue a correction, the employee can contact the IRS for assistance. The IRS can initiate a Form W-2 complaint on the employee’s behalf, sending a letter to the employer requesting the corrected form within ten days.

If the corrected W2 is still not received in time to file the tax return, the employee may use Form 4852, Substitute for Form W-2, Wage and Tax Statement. This form allows taxpayers to estimate their wages and withheld taxes based on available information, such as a final pay stub, for tax filing purposes.

After receiving a corrected W2 (Form W-2c) or if the original tax return was filed using incorrect W2 information, an amended tax return may be necessary. This involves filing Form 1040-X, Amended U.S. Individual Income Tax Return, to adjust previously reported income, deductions, credits, or filing status.

When filing Form 1040-X, taxpayers must explain the changes and attach any supporting documents, including the corrected W2.

Consequences of Uncorrected W2 Information

Failing to correct an inaccurate W2 and filing a tax return based on erroneous information can lead to negative outcomes. A primary consequence is an incorrect tax liability, resulting in either an underpayment or overpayment of taxes.

An underpayment might lead to unexpected tax bills, while an overpayment means a smaller refund or paying more than necessary.

The IRS may impose penalties for inaccurate returns, particularly if the underpayment is substantial due to negligence or disregard of tax rules.

An accuracy-related penalty is 20% of the underpayment. For individuals, a substantial understatement of tax exists if the liability is understated by the greater of 10% of the tax required or $5,000.

Uncorrected W2 information can also lead to delayed tax refunds, as the IRS may flag discrepancies between the taxpayer’s return and the information reported by the employer.

This can prolong processing time for refunds and lead to additional scrutiny. Future tax filings may become more complicated, as inconsistencies from prior years can trigger further reviews or audits.

Beyond immediate tax implications, misreported wage information can affect an individual’s Social Security and Medicare benefits.

The Social Security Administration uses wage data from W2 forms to calculate future retirement, disability, and survivor benefits. If wages are consistently underreported, it could result in lower benefits than an individual is entitled to receive, impacting long-term financial security.
