How to Complete a Form W-2 For Employees: Everything Employers Need to Know for 2026TY

Understanding Form W-2 and Why Employers Must Prepare It

Form W-2, Wage and Tax Statement, is the annual report employers filed with the Social Security Administration (SSA). It is used to report employee wages and taxes withheld.

The form has to be filed for every employee from whom you withheld any federal income, Social Security, or Medicare tax, or whom you paid $2,000 or more in wages.

This form applies to any business with employees on their payroll. Employees use their copies of the form to file their own federal and state returns. Information an Employer Needs Before Creating the W-2

In order to learn how to fill out a W-2 for an employee correctly, start with reconciled year-end payroll data. Before creating Forms W-2 for 2026, employers should verify the following information:

• Employee legal name, SSN and current address
• Legal business name, EIN, and business mailing address
• Year-end payroll register, reviewed and reconciled against employment tax returns and year-end totals
• Any taxable fringe benefits, if required
• Correct Box 12 codes to report type of compensation, benefits, deductions, and tax-related items
• State and local payroll data confirmed

Note: Box 14 has now been split into Box 14a (Other) for employer-use items, and Box 14b for Treasury Tipped Occupation Codes (TTOC).

From Start To Finish: How to Create a Form W-2 for an Employee

Here is how to create a W2 form for an employee using your finalized and reconciled payroll data:

1. Gather employee and employer identification details
   Use the EIN as shown on the employment tax returns. Enter each employee’s legal name, address, and SSN from payroll records.
2. Calculate the total taxable wages
   Report federal taxable wages, tips, and other compensations in Box 1.
3. Complete the wage and withholding boxes
   Enter federal income tax withheld, if any, in Box 2. Social Security wages and tax withheld in Boxes 3 and 4, and Medicare wages and tax withheld in Boxes 5 and 6.
4. Add reportable compensation items
   Learning how to report wages on Form W-2 accurately means using the correct IRS-designated code in Box 12 for retirement deferrals, total cash tips, qualified overtime, and other coded items.
5. Complete state and local information
   Fill in Boxes 15 through 20 for applicable state and local wages, withholding, and locality information.
6. Review before issuing the form
   Compare all reportable amounts against payroll records before furnishing employee copies and submitting to the SSA.

Form W-2 Filing Scenarios for Real-life Payroll Situations

An hourly employee with wages only:
Report wages and withholding, Social Security, and Medicare amounts in Boxes 1 through 6 plus state boxes, if applicable.

An employee with 401(k) deferrals:
The amount reported in Box 1 will be lower than gross pay because 401 (K) deferral reduces federal taxable income. Report the deferral in Box 12 using code D.

An employee received a reportable tip:
 Report the total cash tips in Box 12 with code TP and enter the TTOC in Box 14b. Reported tips are also included in Boxes 1 and 5 and in Box 7 for Social Security tips.

An employee has worked in more than 1 state:
Use Boxes 15 through 20 to report each state’s wages, withholding, and ID number. Issue a second form if more than 2 states must be reported.

A correction was required after filing:
File Form W-2c as soon as you discover the error and furnish the corrected copy to the employee promptly. Add Form W-3c as the transmittal cover for paper corrections
