Form W-2: How to Fill Out the Wage and Tax Statement (Employer Guide)

Every employer who withheld federal income tax, Social Security tax, or Medicare tax from an employee in 2026, or who paid that employee $2,000 or more in wages even without withholding anything, has to send them a completed Form W-2 by January 31, 2027 (the deadline actually falls on February 1, 2027, since January 31 is a Sunday). The form itself is short, but it packs a lot of small, easy-to-mix-up boxes into one page, and a wrong number means issuing a correction later. Here is how to fill one out for a real employee, box by box, working in a PDF you can complete in your browser rather than by hand.

Who Must File a Form W-2 and When It's Due

You must complete a W-2 for every employee you paid wages to during the year, as long as you withheld any income, Social Security, or Medicare tax, or you paid them $2,000 or more even if no tax was withheld. This applies whether you have one employee or two hundred, and it applies to household employers too, if you paid a nanny or caregiver $3,000 or more in cash wages in 2026, you owe them a W-2 even though you never had payroll software involved. Independent contractors do not get a W-2, they get a Form 1099-NEC instead, and mixing the two up is one of the most common payroll mistakes small business owners make.

First-time employers often assume a W-2 is only worth doing through paid payroll software. It is not. If you have one or two employees and already track wages and withholding in a spreadsheet, filling out the actual PDF form yourself takes a few minutes once you have the numbers in front of you.

Two deadlines matter, and they land on the same date. You must furnish employee copies (B, C, and 2) by January 31 each year, and you must file Copy A with the Social Security Administration by that same date, whether you file on paper or electronically. For 2026 forms, that date is February 1, 2027. If your business files 10 or more information returns in total across all types, W-2s, 1099s, and others combined, you are required to e-file rather than mail paper forms.

Information You Need Before You Start

Gather this before you open the form so you are not stopping halfway through:

• Your Employer Identification Number (EIN) and state employer ID number
• The employee's full legal name exactly as it appears on their Social Security card, and their Social Security number
• Total wages, tips, and other compensation paid during the year
• Federal, state, and local income tax withheld
• Social Security and Medicare wages and tax withheld
• Any pre-tax benefits that need a Box 12 code, such as 401(k) contributions, HSA contributions, or the cost of employer-sponsored health coverage

Start from our fillable W-2 template, or upload your own blank copy at pdfeditify.com/fill-pdf, and type directly into every field instead of lining up a typewriter or printing multiple drafts by hand.

Step by Step: Filling Out Each Box

Boxes a through f cover identification: your EIN, your business name and address, the employee's Social Security number, and the employee's legal name and address exactly as SSA has it on file. A name mismatch here is the single biggest cause of processing delays, so double-check spelling against the employee's Social Security card rather than their preferred name.

Box 12 trips up more employers than any other section because it uses letter codes instead of plain labels. If an employee had 401(k) contributions withheld, that goes in with code D and the dollar amount, not folded into Box 1. If you provide health coverage, the total cost (employer and employee portions combined) goes in with code DD, purely for informational purposes, it is not taxable income.

Here is what that looks like for a real employee. Say Maria earned $52,000 in 2026, had $4,600 in federal income tax withheld, and contributed $2,000 to a 401(k) through payroll. Box 1 would show $50,000 (her $52,000 salary minus the $2,000 pre-tax 401(k) deferral, since that money was never taxed as income). Box 2 would show the $4,600 withheld. Boxes 3 and 5 would both show $52,000, because Social Security and Medicare wages are not reduced by 401(k) contributions the way federal taxable wages are. Box 12 would carry a line reading "D 2000.00" to report the deferral separately. If your business also provided her health coverage costing $9,400 for the year (employer plus employee share), that amount goes on a second Box 12 line coded "DD," purely informational and not added to Box 1.

W-2 vs 1099: Making Sure You're Using the Right Form

A W-2 is only for employees you control the work of and from whom you withhold payroll taxes. If someone invoices you, sets their own hours, and pays their own self-employment tax, they are a contractor and should have filled out a Form W-9 when you hired them, not a W-4. Our W-2 vs W-4 comparison covers the distinction between the form you send employees at year-end and the form they fill out when they're hired, which is a separate source of confusion for new employers.

The test the IRS actually applies is behavioral and financial control: do you set the person's schedule, provide their tools and workspace, and direct how the work gets done, or do they run their own business and simply deliver a result to you? If you control the how, not just the what, that person is almost always an employee, regardless of what your contract with them calls them.

If you classify someone incorrectly and later need to fix it, you cannot simply edit the original W-2. You file a Form W-2c, a correction form, and in serious misclassification cases you may also owe back payroll taxes. Getting the classification right the first time avoids that entirely.

Distributing Copies to Employees and the SSA

A completed W-2 actually produces six copies, each going somewhere different: Copy A to the SSA, Copy 1 to your state or local tax department if one applies, Copies B and C to the employee (for their federal and personal records), Copy 2 to the employee for their state return, and Copy D stays in your files. Once you have filled in the fields, you can add your electronic signature to the transmittal Form W-3 and to any updated Forms W-4 employees submit for the new year at pdfeditify.com/sign-pdf, all without printing anything.

Missing the deadline is expensive. For 2026, penalties start at $60 per form if you correct within 30 days, rise to $130 per form if corrected by August 1, and reach $340 per form after that, doubled for intentional disregard of the requirement. There is no grace period; the clock starts the day after the deadline. Those per-form penalties can apply twice, once for filing late with the SSA and again for furnishing the employee copy late, so a handful of missed W-2s adds up fast for a small business.

Many states also require their own year-end wage statement filing separate from the federal copy sent to the SSA, so check your state department of revenue's site before you consider the job finished. If you catch an error after filing, whether it's a wrong Social Security number, an incorrect wage amount, or a missing Box 12 code, correct it on Form W-2c as soon as you notice, since penalty tiers are based on how quickly you fix a mistake, not just whether one occurred.

If your business only handles a small batch of W-2s once a year, paying for a full year of PDF software subscription just for this one task rarely makes sense. PDF Editify's One Week Plan is a $3 one-time charge that expires on its own, so you are not stuck canceling a recurring subscription in February the way you would with most PDF and e-signature tools.
