No — you don’t fill out a W-2 at all, in any year. Your employer prepares that form and sends it to you each January. The form you’re thinking of is almost certainly the W-4, which you complete when you start a job and update only when something in your life or finances changes. There’s just one situation where the W-4 must be refiled every year, and it applies to a narrow group of workers.
The W-2 Is Your Employer’s Job, Not Yours
A W-2, officially the Wage and Tax Statement, is produced by your employer from payroll records. It reports your annual wages, federal and state income tax withheld, and your Social Security and Medicare contributions.1Internal Revenue Service. About Form W-2, Wage and Tax Statement You don’t provide any of the numbers, sign it, or file it yourself. Employers must deliver it to you by January 31 for the prior calendar year.2Office of the Law Revision Counsel. 26 U.S. Code 6051 – Receipts for Employees Your role is to use it when preparing your own tax return.
The W-4 Is the Form You Actually Fill Out
The W-4, called the Employee’s Withholding Certificate, tells your employer how much federal income tax to take out of each paycheck. You’re required to submit a signed W-4 when you start any new job.3Internal Revenue Service. Hiring Employees If you don’t, your employer must withhold as though you’re a single filer with no other adjustments, which usually pulls more out of your check than necessary.4Office of the Law Revision Counsel. 26 U.S. Code 3402 – Income Tax Collected at Source
After that first submission, there is no requirement to file a new W-4 each year. The one you turned in stays in effect until you replace it. That’s the direct answer for most workers: file it once, leave it alone unless something changes.
When You Should Submit a New W-4
“Stays in effect” is not the same as “stays accurate.” Certain life events shift how much tax should be coming out of each paycheck, and the IRS points to several that should prompt a fresh W-4.5Internal Revenue Service. Publication 505 (2025), Tax Withholding and Estimated Tax
- Getting married or divorced, since your filing status changes your bracket.
- Having or adopting a child, which may qualify you for the child tax credit.
- Starting a second job, or your spouse starting work, because the added income can push you into a higher bracket.
- Picking up significant non-wage income such as dividends, rental income, or freelance earnings. Without an adjustment, you can end up with an underpayment penalty.6Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty
- A child turning 17 and aging out of the child tax credit at the full rate. If your W-4 still claims it, your withholding needs to go up.
Timing matters in one direction. If a change means you’re now entitled to less of a withholding reduction than your current W-4 claims (for example, a divorce, or a dependent no longer qualifying), you must submit a corrected W-4 within 10 days.5Internal Revenue Service. Publication 505 (2025), Tax Withholding and Estimated Tax Changes that would increase your withholding allowance, like a new baby, can be submitted whenever you want. Waiting just means your paychecks won’t reflect the change until you act.
Once you turn in a new W-4, your employer must put it into effect no later than the start of the first payroll period ending 30 or more days after they receive it.7Internal Revenue Service.

The One Case Where You Must Refile Every Year: Claiming Exempt
There is a single situation where a W-4 has to be redone annually. If you’re claiming exemption from withholding, that exemption only lasts through December 31. To keep it in place, you must submit a new W-4 claiming exempt status by February 15 of the following year.7Internal Revenue Service. Topic No. 753, Form W-4, Employees Withholding Certificate
Miss that February 15 deadline and your employer must start withholding at the maximum default rate — single filer, no adjustments. To qualify for exempt status in 2026, you must have owed no federal income tax for 2025 and reasonably expect to owe none for 2026.8Internal Revenue Service. Form W-4 (2026) Employee’s Withholding Certificate This mainly applies to workers with very low income, such as students or part-time employees earning below the standard deduction threshold. If you’re not claiming exempt, the annual refiling requirement doesn’t apply to you.
Adjusting Your W-4 Honestly
Changing your W-4 to reduce withholding is legal when the entries reflect your actual situation. Claiming credits or deductions you know you don’t qualify for, in order to keep more of each paycheck, is not. The IRS can impose a $500 civil penalty for each false statement that results in less tax being withheld.9Office of the Law Revision Counsel. 26 U.S. Code 6682 – False Information with Respect to Withholding The standard is whether you had a reasonable basis for what you put on the form. Following the W-4 instructions honestly using real numbers keeps you clear even if the final result is slightly off.
If You’re a Contractor, You Won’t Get a W-2 at All
Not every worker gets a W-2. If you’re classified as an independent contractor rather than an employee, you’ll receive a 1099-NEC and no taxes are withheld from your pay. You’re responsible for making estimated payments during the year and covering both the employee and employer shares of Social Security and Medicare.
The IRS looks at three factors to decide which category you fall into: whether the business controls how the work is done, whether it controls the financial side (how you’re paid, whether expenses are reimbursed), and the type of relationship between the parties.10Internal Revenue Service. Worker Classification 101: Employee or Independent Contractor If a company sets when, where, and how you work and supplies the tools, you’re likely an employee who should receive a W-2, whatever the company calls you. A worker who believes they’ve been misclassified can file Form SS-8 with the IRS to request a determination.
The Short Version
You never fill out a W-2. Your employer produces it and sends it to you each January. The W-4 is the form you complete, and once it’s on file with your employer it stays in effect year after year. Update it when your life or income changes, submit a corrected one within 10 days if a change reduces the withholding allowance you were claiming, and file a fresh one by February 15 each year only if you’re claiming exemption from withholding.
