The Basics: What Is a W-2 Form?
A W-2, officially called the Wage and Tax Statement, is an IRS form employers use to report how much they paid you during the tax year and how much tax they withheld. In short, it tells both you and the tax authority (the IRS) how much you earned and how much you’ve already paid in federal, state, and local taxes.
If you’re a W-2 employee, your employer manages your tax payment and tax withholding compliance, including Social Security and Medicare contributions, state income taxes, and federal income taxes. This setup differs from that of an independent contractor, who typically receives a 1099 and must handle their own tax compliance and filing taxes.
What’s on a W-2?
A W-2 includes key information you’ll need for your tax filings and benefits administration, such as:
- Wages, tips, and compensation (your total earnings)
- Federal income tax withheld
- Social Security and Medicare taxes withheld
- State and local income tax information
- Employer identification number (EIN)
- Employee details including filing status and address
Each box on the form corresponds to a different aspect of your income or taxes, making it the foundation for filing your annual tax return. This makes your W-2 essential for preparing an accurate return and maximizing your tax deductions.
W-2 vs. 1099: What’s the Difference?
The biggest difference between a W-2 and a 1099 comes down to employment classification:
This distinction matters — not only for taxes but also for human resources, benefits administration, and employment law. Misclassifying a worker as a 1099 when they should be a W-2 can result in steep penalties and tax liability for the employer.

If you’re wondering how a W-4 fits into the picture, we’ve got you covered.

(Hint: W-2s summarize the past. W-4s prepare you for the future.)
Why Employers Use W-2s
Employers issue W-2s for all employees who earned at least $600 during the tax year. This ensures compliance with federal, state, and local tax authority requirements. Accurate W-2s also simplify tax filings, tax deductions, and tax compliance for both employers and employees.
For organizations managing complex workforces — especially across multiple states — this process can get complicated fast. That’s where an Employer of Record (EOR) or Professional Employer Organization (PEO) like TCWGlobal comes in.
We handle payrolling, benefits administration, tax reporting and assist with compliance across jurisdictions, ensuring every worker gets the right form, from Social Security and Medicare reporting to state income taxes. It’s compliance made simple, so your HR team can focus on growth instead of red tape.
When to Expect Your W-2
By law, employers must send out W-2s by January 31 each year. You may receive it via mail, email, or through your employer’s payroll portal.
If you work through an EOR or PEO like TCWGlobal, your W-2 will come from that organization, not directly from the company where you performed the work.
If it’s mid-February and your W-2 still hasn’t arrived, check your spam folder or reach out to your human resources or payroll team for help.
Why Understanding Your W-2 Matters
Your W-2 isn’t just a tax form — it’s a roadmap to your tax liability and a summary of your contributions to Social Security and Medicare. Understanding it helps you:
- File your tax filings accurately and on time
- Avoid costly compliance errors
- Catch payroll or tax deduction issues early
- Ensure alignment with tax authority requirements
- Plan future retirement plans and benefits administration strategies
Whether you’re an employee or an HR leader, knowing how to read a W-2 ensures your organization stays compliant and efficient during every tax year.
