What's on a W-2?

While many of the items listed below don't apply for each and every business, we've provided an explanation of W-2 Earnings Summary below. (Please visit www.irs.gov for a complete listing).

Box 1: Wages, tips, and other compensation. Box 1 reports total taxable wages for federal income tax purposes. This figure includes wages, salary, tips reported, bonuses, and other taxable compensation. Any taxable fringe benefits (such as group term life insurance) are also included in Box 1 wages.

Box 2: Federal income tax withheld. Box 2 reports the total amount withheld from paychecks for federal income taxes. This represents the amount of federal taxes that have been paid-in throughout the year.

Box 3: Social Security wages. Box 3 reports the total amount of wages subject to the Social Security tax.

Box 4: Social Security tax withheld. Box 4 reports the total amount of Social Security taxes withheld from paychecks.

Box 5: Medicare wages and tips. Box 5 reports the amount of wages subject to Medicare taxes. There is no maximum wage base for Medicare taxes. The amount shown in Box 5 may be larger than the amount shown in Box 1. Medicare wages includes any deferred compensation, 401(k) contributions, or other fringe benefits that are normally excluded from the regular income tax. In other words, the amount in Box 5 typically represents the entire compensation.

Box 6: Medicare tax withheld. Box 6 reports the amount of taxes withheld from paycheck for the Medicare tax.

Box 7: Social Security tips. Box 7 reports the amount of tip income reported to the employer. If tips are not reported to the employer, an amount will not be in this box. The amounts in Box 7 and Box 3 should add up to the amount in Box 1, or the maximum wage limit for Social Security taxes.

Box 8: Allocated tips. Box 8 reports any tip income that an employer thinks an employee may have earned, but failed to report. This amount is not included in the wages reported in Boxes 1, 3, 5, or 7.

Box 10: Dependent Care Benefits. Box 10 reports any amounts reimbursed for dependent care expenses, or the dollar value of dependent care services provided by your employer. Amounts under $5,000 are non-taxable benefits. Any amount over $5,000 is reported as taxable wages in Boxes 1, 3, and 5. Non-taxable benefits must be excluded from expenses claimed for the child and dependent care tax credit on IRS Form 2441.

Box 11: Nonqualified Plans. Box 11 reports any amounts distributed to an employee from the employer's non-qualified deferred compensation plan or non-government Section 457 pension plan. The amount in Box 11 is already included as taxable wages in Box 1.

Some employers report certain state and local taxes in Box 14, such as State Disability Insurance (SDI) premiums.
