Your Form W-2 impacts your federal and state tax filings. It’s therefore imperative that you get your W-2 on time. But what is a W-2? When should you receive it? How do you read a W-2? And what should you do if you find an error on your W-2? Read on for answers.
What is a W2?
IRS Form W-2, Wage and Tax Statement, is used by employers to report employees’ annual wages and salaries, taxes withheld, and other compensation. Your employer must give you:
- Your Form W-2 if they paid you at least $600 for the year
- Copy B to file with your federal income tax return
- Copy 2 to file with your state or local tax return, if applicable
- Copy C to retain for your records
Only employees receive form W-2.
When does a W2 come out?
Your employer has until January 31 to furnish Forms W-2 to employees. If the deadline falls on a Saturday, Sunday, or legal holiday, your employer must furnish Forms W-2 by the following business day. Employers that provide online access to Forms W-2 must do so by January 31. Those that don’t supply online access must mail or hand-deliver Forms W-2 no later than January 31. If don’t receive your Form W-2 by the deadline, let your employer know so they can resolve the issue.
How to read a W-2 form?
Though your Form W-2 is essentially about how much money you earned and the amount of taxes you paid, it’s also a detailed document. It shows, for instance, your retirement plan contributions, the amount your employer paid for your health insurance, and nontaxable income you received from your employer.
Here’s a breakdown of relevant W-2 boxes:
- Box 1:
- Total wages — including salaries, tips, and other compensation — subject to federal income tax. Box 1 does not show pre-tax deductions or nontaxable wages.
- Box 2:
- Federal income tax withheld from your wages.
- Box 3:
- Wages subject to Social Security tax. This amount should not exceed the annual Social Security wage limit.
- Box 4:
- Social Security tax withheld from your wages.
- Box 5:
- Wages subject to Medicare tax. No annual wage limit applies to Medicare tax.
- Box 6:
- Medicare tax withheld from your wages. This includes regular Medicare tax, and if applicable, the additional Medicare tax of 0.9% for high-income earners.
- Box 7:
Tips you reported (to your employer) that were subject to Social Security tax. This amount is also reflected in Box 1 wages.
- Box 8:
- Tips your employer allocated to you. This amount is not shown in Box 1 wages.
- Box 10:
- Dependent care benefits you received from your employer. If you contributed more than the annual pre-tax limit, the excess amount is taxable and includable in Box 1 wages.
- Box 11:
- Taxable amounts distributed to you from your employer’s non-qualified deferred compensation plan.
- Box 12:
- Used to deliver information about various types of compensation and benefits, such as taxable group-term life insurance, elective deferrals to a 401(k) plan, Roth 401(k) contributions, adoption benefits, nontaxable sick pay, and cost of employer-sponsored health coverage. Refer to the IRS guidelines on values for this field.
- Box 13:
- Your employer must check whichever applies:
- You’re a statutory employee
- You contributed to your employer’s retirement plan
- You received third-party sick pay
- Box 14:
- Other information your employer wants you to know, such as state disability insurance tax withheld, union dues, tuition assistance payments, health insurance premiums deducted, and uniform payments.
- Box 16:
- Wages subject to state income tax.
- Box 17:
- State income tax withheld from your wages.
- Box 18:
- Wages subject to local taxes, such as city or county taxes.
- Box 19:
- Local taxes withheld from your wages.
What if there’s an error on my W2 form?
If you see a mistake on your W-2 — such as incorrect name, incorrect Social Security Number, incorrect wages, or incorrect taxes withheld — let your employer know as soon as possible. Depending on the error, your employer may need to give you a corrected W-2 via Form W-2c, which you can then use to amend your tax returns if necessary.
