Processing W-2s means gathering year-end payroll data for each employee, completing Form W-2, distributing copies to employees by January 31, and filing Copy A with the Social Security Administration by January 31, whether you file on paper or electronically. When January 31 falls on a weekend or holiday, the deadline shifts to the next business day.
The W-2 reports what you already know: wages paid and taxes withheld. If you've been running payroll all year, every figure on the form is already in your payroll records. The 2026 filing year adds three new Box 12 codes and a revised Social Security wage base, each addressed in the section where they apply.
SurePayroll By Paychex builds W-2s from your payroll records throughout the year, so January filing is a review, not a rebuild.
What is Form W-2 and who needs one
Form W-2, also known as the Wage and Tax Statement, is the annual form you issue to every employee from whom you withheld federal income tax, Social Security tax, or Medicare tax during the tax year, regardless of how much you paid them. You also file a W-2 for any employee you paid $2,000 or more during the year, even if no federal tax was withheld. (See IRS About Form W-2 Wage and Tax Statement)
What you report on Form W-2 determines each employee's taxable income and whether they receive a tax refund or owe a balance when they file their return.
Form W-2 is one of nearly 4.6 billion information returns the IRS processes each year, along with 1099 forms and other documents your business may file. (Source: IRS Publication 6961, CY 2024)
Independent contractors get a 1099 form rather than a W-2. You issue Form 1099-NEC to each contractor you paid $2,000 or more in 2026. The split is straightforward: W-2s are for employees. 1099-NECs go to contractors who manage their own withholding. (About IRS Form 1099-NEC, Nonemployee Compensation)
If your team is a mix, you prepare both. Both are due January 31, but they have different reporting rules.

How to process W-2s step by step
W-2 processing is a sequence, not a one-time form-fill. Work through these seven steps in order and you close out January with documentation that matches your quarterly filings.
Step 1: Gather your year-end payroll records
Collect total wages paid, federal income tax withheld, Social Security tax withheld, Medicare tax withheld, and any state or local withholding for each W-2 employee. These figures come from your payroll records, your Form 941 filings, and your employees' Form W-4 elections.
You also need each employee's name, Social Security number (SSN), and current address. Confirm SSNs against your payroll records and verify any address changes from the past year. A wrong SSN, a misspelled name, or an incorrect address can trigger a rejected wage report or a delayed delivery.
Step 2: Reconcile your payroll totals to your quarterly 941 filings
Add up your four quarterly Form 941 (Employer's Quarterly Federal Tax Return) filings and confirm those totals match your combined W-2 wages and withholding. Your 941 totals (lines 2 through 5d) should reconcile with your aggregate W-2 totals across all employees, plus or minus standard fourth-quarter adjustments.
Step 3: Complete Form W-2 for each employee
Enter each employee's wages, withholding amounts, and any benefits or deductions in the correct boxes. Work box by box: wages, federal withholding, Social Security wages and tax, Medicare wages and tax, state wages, and all applicable Box 12 codes. Section 3 of this guide walks through each box in detail.
Step 4: Verify your EIN and each employee's SSN and legal name
Before filing, confirm your employer identification number (EIN) is correct, and verify each employee's Social Security number and legal name exactly as it appears on their Social Security card. The Social Security Administration (SSA) rejects returns when names and Social Security numbers do not match, and a rejected filing means you refile, which means you miss your deadline. Verify before you submit.
Step 5: Distribute W-2 copies to employees by January 31
Every employee receives Copy B, Copy C, and Copy 2 of their W-2 by January 31. When January 31 falls on a weekend or holiday, the deadline shifts to the next business day. For the 2026 tax year, that is Monday, February 1, 2027. Electronic delivery requires written consent from the employee in advance.
Step 6: File Copy A and Form W-3 with the SSA
File Copy A of every Form W-2 and Form W-3 with the SSA by January 31, whether you file on paper or e-file. The same weekend and holiday shift applies: for the 2026 tax year, the deadline is Monday, February 1, 2027. If you file 10 or more information returns across all form types in a calendar year, federal law requires you to e-file.
Step 7: Retain Copy D for your employer records
Keep Copy D of each W-2 for a minimum of four years. Copy D does not get filed with any agency. It is your record of what you reported, and you will need it if a discrepancy surfaces later.
This is detail-heavy work, and the stakes are real. In a survey of SurePayroll customers, nearly 4 in 10 small business owners who switched to SurePayroll cited the time payroll was taking. Another 38% wanted to eliminate the risk of errors. Year-end filing is both.
SurePayroll tracks the figures you need throughout the year, so year-end totals pull directly from your payroll records.

How to fill out each W-2 box
Form W-2 has three groups: identifying information in Boxes A through F, wage and withholding totals in the numbered boxes, and special compensation codes in Box 12. Work through each group in order, one employee at a time.
Above the numbered boxes, enter your employer identification number (EIN), your company's name and address, and for each employee, their legal name, Social Security number, and current mailing address. Use a control number if your payroll system assigns one.
Completing W-2 step by step
Box 1: Enter total taxable wages for federal income tax. Start with gross pay and subtract pre-tax deductions: traditional 401(k) contributions, health insurance premiums through a Section 125 plan, and pre-tax FSA contributions. An employee earning $60,000 who contributes $5,000 to a 401(k) has $55,000 in Box 1.
Box 2: Enter federal income tax withheld, taken directly from your payroll records.
Boxes 3 and 4: Enter Social Security wages in Box 3, capped at $184,500 for 2026, and Social Security tax withheld at 6.2% of Box 3 in Box 4. (Social Security Contribution and Wage Base)
Boxes 5 and 6: Enter Medicare wages in Box 5 (no annual cap) and Medicare tax withheld at 1.45% of Box 5 in Box 6. Add the additional 0.9% surtax for any employee whose wages exceed $200,000.
Box 7: Enter Social Security tips your employees report to you.
Box 8: Enter allocated tips -- the amount you assign when a tipped employee's reported tips fall below 8% of gross receipts at a large food or beverage establishment.
Box 9: Leave blank. The IRS does not currently use this box.
Box 10: Enter dependent care benefits paid through a qualified plan.
Box 11: Enter non-qualified deferred compensation distributions paid to the employee during the year.
Box 12: Enter compensation and benefit codes from your payroll records. The codes most small businesses use: Code D for 401(k) contributions, Code W for HSA contributions (employer and employee), Code DD for employer-sponsored health coverage cost (informational; not taxable), Code TP for qualified tips, and Code TT for the qualified overtime premium. Code TA applies for 2026.
Box 13: Check all boxes that apply: statutory employee, retirement plan participant, or third-party sick pay recipient.
Box 14: Use for items with no dedicated box: union dues, after-tax health insurance premiums, post-tax retirement contributions, or state-specific amounts.
Box 14b: Enter the tipped occupation code.
Boxes 15 through 17 cover state wages, state tax ID numbers, and state income tax withheld. If an employee worked in multiple states, complete a separate row for each.
S-corp and independent contractors
If you own an S-corp and pay yourself a salary, report that salary on a W-2 like any other employee. Shareholder distributions do not appear on the W-2.
If your team includes W-2 employees and 1099 contractors, prepare Form 1099-NEC for each contractor and Form 1096 as the transmittal summary for paper filings.

2026 W-2 updates
The Social Security wage base and three Box 12 codes changed for tax year 2026.
Social Security wage base: $184,500. The 2026 cap is up from $176,100 in 2025. Box 3 wages cap at $184,500; Box 4 reflects 6.2% of that amount.
Code TP: Qualified tips. Report qualified tips your employees receive and report to you in Box 12 with Code TP. This reporting requirement is new for 2026.
Code TT: Qualified overtime premium. Report the overtime premium -- the half-time differential in time-and-a-half pay -- not total overtime pay. If you pay $30 per hour and an employee works an overtime hour at $45, you enter $15 under Code TT. This code was voluntary in 2025 through Box 14; it is mandatory in Box 12 starting with the 2026 tax year.
Code TA: Trump Account contributions. Report employer contributions to an eligible child's Trump Account -- the savings accounts created by the One Big Beautiful Bill, effective July 4, 2026 -- in Box 12 with Code TA. If you contributed on behalf of an employee's eligible child, enter the total amount here.
For a complete list of Box 12 codes and all Form W-2 reporting requirements, refer to the IRS General Instructions for Forms W-2 and W-3.
How to distribute W-2s to your employees
Send Form W-2 to every employee on your payroll for any part of the prior tax year by January 31, including employees who left mid-year, employees on leave at year-end, and seasonal workers. For the 2026 tax year, that deadline is February 1, 2027. The deadline is the same regardless of how many hours they worked or when they separated.
Each employee receives four copies:
- Copy B: Employee files with their federal tax return
- Copy C: Employee keeps for their own records
- Copy 2: Employee files with their state or local tax return (if applicable)
- Copy D: You keep for your employer records -- do not file it with any agency
Copy 1 goes to the state or local tax department, if your state requires it.
Paper delivery
Mail paper copies to the employee's last known address, or hand-deliver them if your team works on-site.
Electronic delivery
Electronic delivery is permitted only with prior written consent from the employee. If consent is not on file before you distribute, paper is required. Employees also need access to a device where they can view and save the file.
SurePayroll generates W-2s from your payroll data, files them electronically, and prepares employee copies for distribution.
How to correct a W-2
Catching a Form W-2 error is a normal part of year-end filing. The correction path depends on whether you have already filed Copy A with the SSA.
If you catch the error before filing
Fix the form and file the corrected version. If you are filing through BSO, the portal flags errors in real time during submission. Address any flagged items before you confirm the filing.
If you catch the error after filing
File Form W-2c, the Corrected Wage and Tax Statement, with the SSA. If you filed on paper, include Form W-3c (Transmittal of Corrected Wage and Tax Statements). When you e-file the correction through BSO, you submit the corrected wage file electronically, which replaces the paper W-3c.
The W-2c shows both the previously reported figures and the corrected figures side by side, so the SSA can update the wage record without confusion.
Common corrections include:
- Wrong wage figure, often traced to a missed pre-tax deduction
- Incorrect employee Social Security number
- Incorrect tax withholding amount
- Employee name change that did not make it into payroll before year-end
Send the corrected Copy B to the employee at the same time you file the W-2c. If the employee has already filed their tax return based on the original W-2, they may need to file Form 1040-X (Amended Individual Income Tax Return) to reconcile the difference.
