Table of Contents

W-2 Instructions 2026 – As tax season approaches in 2026, understanding Form W-2 is essential for both employees and employers. This IRS tax form, officially known as the Wage and Tax Statement, summarizes an employee’s earnings and tax withholdings for the previous calendar year (2025 in this case). Whether you’re an employee figuring out how to read your W-2 for accurate tax filing or an employer learning how to fill it out correctly, this guide covers everything based on the latest IRS guidelines. We’ll break down each box, highlight key changes for 2026, and provide tips to avoid common pitfalls.

Form W-2 is required if an employer paid at least $2,000 in wages (up from $600 in prior years) or withheld any federal income, Social Security, or Medicare taxes. Employers must furnish copies to employees by February 1, 2027, and file with the Social Security Administration (SSA) by the same date for electronic filings. Let’s dive into the details.

What is Form W-2 and Why Does It Matter in 2026?

Form W-2 reports your annual wages, tips, and other compensation, along with taxes withheld. Employees use it to file their federal and state tax returns (e.g., Form 1040), while employers submit it to the IRS and SSA to ensure accurate reporting. For 2026 filings (covering 2025 wages), key updates include:

Social Security wage base increased to $184,500.
Medicare tax remains unlimited, with an additional 0.9% on wages over $200,000.
New Box 12 codes: TA (employer contributions to Trump accounts, up to $2,500), TP (total cash tips reported), and TT (qualified overtime compensation).
Box 14 split into 14a (Other) and 14b (Treasury Tipped Occupation Code(s)).
Health FSA contribution limit: $3,400.
Qualified Small Employer Health Reimbursement Arrangement (QSEHRA) benefits up to $6,450 (Code FF in Box 12).
Increased penalties for late or incorrect filings, starting at $60 per form and up to $340 for intentional disregard.

Failing to understand or complete the form correctly can lead to IRS audits, penalties, or delayed refunds. If you’re an employee, expect your W-2 by early February 2026.
