What Is a W-2 Form? 2026 Boxes, Codes, and Corrections

Updated: August 30, 2026

Published by DG Paystub Editorial Team. A source-based guide to the 2026 Form W-2: what the wage and tax boxes report, new codes TP and TT, Box 14b, deadlines, and correction steps.

What Is Form W-2?

Form W-2, Wage and Tax Statement, is an annual information return used to report specified wages, taxes, and other payroll items for an employee. The employer furnishes employee copies and files wage information with the Social Security Administration under the applicable rules.

Form W-2 is not a pay stub. A pay statement usually explains one payroll calculation; Form W-2 reports calendar-year amounts using federal reporting definitions.

Use the final form and instructions for the correct year. This guide covers the 2026 form based on the IRS's current 2026 General Instructions for Forms W-2 and W-3, last checked August 30, 2026.

Who Receives a W-2?

The IRS Form W-2 overview explains the employer filing requirement for remuneration paid for services performed by an employee. The detailed instructions include thresholds, special cases, and exceptions.

Whether a worker is an employee or independent contractor is not determined by the document the business prefers to issue. Classification depends on the governing legal tests and the facts of the relationship. The IRS explains its federal tax framework in Publication 15-A.

Working part of a year, changing jobs, or leaving before year-end does not merge employer records. A worker may receive more than one W-2 when more than one employer paid reportable wages or when an employer must use an additional form under the instructions.

W-2 Identification Boxes

Do not post or email an unredacted W-2 through an unverified channel. It contains information useful for identity theft.

Boxes 1–6: Federal Wage and Tax Categories

Box 1 — Wages, tips, other compensation

Box 1 reports amounts included under its federal income-tax reporting definition. It is not automatically equal to salary, payroll gross, take-home pay, Social Security wages, or Medicare wages.

Box 2 — Federal income tax withheld

Box 2 reports federal income tax withheld. It is one input to the federal income-tax return; it does not, by itself, determine a refund or balance due.

Box 3 — Social Security wages

Box 3 reports wages subject to Social Security tax under the W-2 instructions, limited by the annual Social Security wage base. The Social Security Administration lists a 2026 contribution and benefit base of $184,500.

Box 4 — Social Security tax withheld

Box 4 reports employee Social Security tax withheld. If multiple employers collectively withhold above the employee maximum, the federal return process may address the excess. A single employer's error follows a different correction process; use the IRS instructions rather than altering a W-2 copy.

Box 5 — Medicare wages and tips

Box 5 reports Medicare wages and tips. It does not use the Social Security wage-base cap and may differ from Boxes 1 and 3.

Box 6 — Medicare tax withheld

Box 6 reports Medicare tax withheld, including Additional Medicare Tax withholding when applicable. The IRS explains the general Social Security and Medicare rates and Additional Medicare Tax withholding in Topic No. 751.

Why Boxes 1, 3, and 5 May Differ

The boxes apply different tax definitions. Differences may result from:

• elective deferrals to a qualified retirement plan;
• certain cafeteria-plan benefits;
• taxable fringe benefits;
• sick pay or other special payments;
• nonqualified deferred compensation; and
• the annual Social Security wage base.

Do not use one generic “pre-tax deduction” rule for every benefit. Check the plan, transaction, and current W-2 instructions. When reconciling, start with the employer's payroll register and map each adjustment to the tax category it affects.

Boxes 7–11

These boxes cover specialized items:

• Box 7: Social Security tips under the form instructions;
• Box 8: allocated tips;
• Box 9: no amount is entered on the 2026 form;
• Box 10: dependent care benefits; and
• Box 11: certain nonqualified-plan amounts.

The tax treatment cannot be inferred from the label alone. For example, a value in Box 8 may require the employee to review tip reporting and supporting records.

Box 12 Codes

Box 12 pairs a code with an amount. The position—12a, 12b, 12c, or 12d—does not change the code's meaning.

Common examples include:

This table is not the complete code list and does not state each item's tax treatment. Read the entry for the exact code in the 2026 W-2 instructions.

New 2026 reporting for tips and overtime

The final 2026 instructions add:

• Code TP for total cash tips reported to the employer;
• Code TT for the amount of qualified overtime compensation defined by the instructions; and
• Box 14b for Treasury Tipped Occupation Code information when applicable.

For Code TT, the instructions distinguish qualified overtime compensation from the entire time-and-a-half payment. Do not assume all overtime earnings shown by payroll belong in Code TT.

These reporting fields relate to provisions enacted in Public Law 119-21. A reported amount is not an automatic promise that a taxpayer qualifies for a deduction or for the maximum amount. Eligibility, limits, phaseouts, filing status, and documentation still matter. Use current IRS return instructions or a qualified tax professional.

Box 13, Box 14a, and Box 14b

Box 13 contains checkboxes for statutory employee, retirement plan, and third-party sick pay. Each has a defined reporting purpose.

Box 14a is used for other information the employer reports. Labels can vary, so ask payroll what an unfamiliar entry means and consult any state instructions that apply.

Box 14b is new on the 2026 form and is used for Treasury Tipped Occupation Code information under the current instructions.

Boxes 15–20: State and Local Information

These boxes report state or local identifiers, wages, withholding, and locality information when applicable. State wages may differ from federal wages because state rules do not always follow federal treatment.

Workers who lived or worked in multiple jurisdictions should not guess which return receives an amount. Compare the W-2 with the relevant state and local tax-agency instructions or obtain qualified advice.

Calendar-Year Reporting

The 2026 instructions state that Form W-2 entries are based on wages paid during the calendar year. A pay period ending in December but paid in January generally belongs to the later calendar year's W-2 under that rule.

That timing is one reason a “December work” total and a calendar-year W-2 can differ.

When Is the W-2 Due?

The general furnishing and filing deadline is January 31, subject to the weekend, legal-holiday, extension, disaster-relief, and special-case rules in the current instructions. January 31, 2027 is a Sunday, so the ordinary next-business-day rule points to February 1, 2027 for 2026 forms. Employers and employees should still verify the current IRS instructions and any announced relief.

Electronic availability depends on employer process, consent requirements, and the applicable rules. Do not assume every portal posts forms on the same date.

What to Do If a W-2 Is Missing

Follow the sequence in IRS Topic No. 154:

1. Confirm the employer has the correct address and check the verified employee portal.
2. Contact the employer or payroll department.
3. Follow the IRS timing and contact instructions if the form still has not arrived.
4. Use Form 4852 only when appropriate and based on the best available genuine records.
5. Correct the tax return if a later W-2 changes information previously filed.

A final pay statement can be supporting evidence, but it does not necessarily contain every W-2 adjustment. Do not merely copy YTD gross into Box 1.

What to Do If a W-2 Is Incorrect

Do not edit the W-2 yourself. Contact the employer and describe the exact identification field or numbered box at issue. Form W-2c is used for applicable corrections; the employer follows the W-2/W-2c filing instructions.

Keep:

• the original W-2;
• any corrected W-2c;
• final employer pay statements;
• benefit and retirement records;
• written payroll correspondence; and
• the tax return and supporting calculation.

If a return has already been filed, use current IRS guidance to determine whether an amended return is needed.

Form Copies and Electronic Filing

The W-2 has copies for the SSA, employee, employer, and state or local use. The required handling depends on whether filings are electronic or paper.

The IRS warns that a Copy A downloaded and printed from IRS.gov is not the scannable official paper Copy A for SSA filing. Employers should use approved electronic filing, official forms, or compliant substitutes. Employees should not try to file the employer's Copy A themselves.

Security Checklist

• Download a W-2 only from a verified employer, payroll-provider, tax-agency, or SSA path.
• Use a unique password and multifactor authentication where available.
• Redact the Social Security number before sharing a copy unless the verified recipient specifically requires it.
• Do not send W-2 data in response to an unsolicited text or email.
• Preserve the original file and avoid editing its amounts or issuer information.
