Question 1

What is Form W-2 and what must employers include on it?

Accepted Answer

Form W-2 is the Wage and Tax Statement that employers must furnish to every employee who received wages, salaries, or other compensation during the tax year, and must also file with the Social Security Administration. It reports total wages paid, federal income tax withheld, Social Security wages and taxes withheld, Medicare wages and taxes withheld, any applicable state income taxes, and local taxes. Form W-2 also includes Box 12, which uses letter codes to report special compensation categories such as employer contributions to health savings accounts (Code W), contributions to 401(k) plans (Code D), and the employer-provided health coverage cost (Code DD) required under the Affordable Care Act. Box 13 contains checkboxes for statutory employees, retirement plan participants, and third-party sick pay. Box 14 is used to report informational items such as union dues, state disability insurance withheld, and other employer-defined categories. Employers must furnish W-2 copies to employees by January 31 and file copies with the SSA by January 31 as well, whether filing paper or electronically. Accurate W-2 preparation requires reconciling payroll records, verifying Social Security Number accuracy, and ensuring that all special pay categories are properly coded.

Question 2

What are the Box 12 codes on Form W-2 and what do they report?

Accepted Answer

Box 12 of Form W-2 contains up to four lettered entries, each using an IRS-assigned code to report specific types of compensation, benefits, or deferrals that have special tax treatment. Common Box 12 codes include Code D for employee elective deferrals to a 401(k) plan, Code E for 403(b) plan deferrals, Code G for 457(b) government plan contributions, Code W for employer contributions to a Health Savings Account (HSA), Code DD for the cost of employer-sponsored health coverage (informational only, not added to taxable wages), Code R for employer contributions to an Archer MSA, Code S for SIMPLE IRA contributions, and Code AA or BB for Roth 401(k) or Roth 403(b) contributions. Code C is used to report the taxable cost of group-term life insurance over $50,000. Code J applies to non-taxable sick pay. Understanding which code applies to each benefit is critical because miscoding Box 12 can affect the employee's ability to correctly complete their tax return and may trigger IRS matching errors. When more than four Box 12 codes are needed, additional W-2 forms or continuation statements are used. Payroll software should be configured with the correct codes for each benefit type at the beginning of the plan year.

Question 3

Can employers provide Form W-2 electronically, and what are the requirements?

Accepted Answer

Employers may furnish Form W-2 electronically to employees, but doing so requires specific compliance steps to protect employee rights and ensure the electronic delivery qualifies as proper notice. The employer must provide employees with clear and conspicuous notice of their right to receive a paper W-2 and obtain each employee's affirmative written or electronic consent to electronic delivery before delivering W-2s electronically. The consent must be obtained in a manner that demonstrates the employee can access the form in the electronic format in which it will be provided. Employees who consent may later withdraw that consent and revert to paper delivery, and the employer must have a procedure in place to process withdrawal requests. Electronic W-2s must be delivered in a format that the employee can access and print, and must be available for at least one full year after the January 31 delivery deadline. Employers cannot require employees to accept electronic delivery as a condition of employment. If the employer uses a third-party payroll provider or employee self-service portal for W-2 distribution, the consent and delivery requirements still apply and the employer remains responsible for compliance. Employees who do not consent to electronic delivery must receive paper W-2s by January 31.

Question 4

How does an employer correct a Form W-2 error using Form W-2c?

Accepted Answer

When an employer discovers an error on a previously issued Form W-2, a corrected Form W-2c must be prepared and furnished to the employee and filed with the Social Security Administration. Form W-2c shows the previously reported amounts in the Previously reported column and the correct amounts in the Correct information column for each box that contains an error. Only the boxes with errors need to be corrected on Form W-2c; boxes that were correct on the original form are left blank. Common errors corrected via W-2c include incorrect Social Security Numbers, wrong employee names, incorrect wage amounts, wrong tax withholding figures, and missing or incorrect Box 12 codes. Employers should correct errors as quickly as possible once discovered, as W-2c copies must be furnished to the employee and the corrected SSA copies filed on Form W-3c, the transmittal for W-2c forms. If the error is discovered before the original W-2 has been filed with the SSA, the employer may void and reissue the W-2 rather than filing a W-2c. Significant Social Security Number errors require the employer to also contact the SSA and may require additional corrective procedures. Payroll system controls that validate SSNs against SSA records prior to W-2 preparation help prevent many common errors.

Question 5

What are the deadlines and penalties for failing to file or furnish Form W-2?

Accepted Answer

Form W-2 has strict filing and furnishing deadlines with significant penalties for non-compliance. Employers must furnish W-2 copies to employees by January 31 of the year following the tax year, and must also file copies with the Social Security Administration by January 31 for both paper and electronic filers. Penalties for failure to furnish correct W-2s to employees or failure to file correct W-2s with the SSA are tiered by the degree of lateness and whether the failure involved correct information. Penalties range from lower amounts for corrections made within 30 days of the due date, to mid-range amounts for corrections made by August 1, to maximum per-form penalties for forms that remain incorrect or unfiled after August 1. Intentional disregard carries substantially higher per-form penalties with no cap. A separate penalty applies for each failure: one for failure to furnish to the employee and one for failure to file with the SSA. Small businesses with annual gross receipts under $5 million qualify for lower maximum penalty amounts. The July 2025 Tax Bill may have adjusted penalty amounts, so professionals should verify current figures annually. Demonstrating reasonable cause for filing failures can support a penalty abatement request, particularly when errors resulted from circumstances outside the employer's control.
