If you are wondering why your W-2 is higher than your salary, the answer is that Box 1 reports every form of taxable compensation you received during the year, not just your base pay. Bonuses, commissions, overtime, the taxable value of certain fringe benefits, stock compensation, reported tips, some reimbursements, and payouts from deferred compensation plans are all folded into that single wages figure. Once you know what to look for, the gap between your salary and Box 1 usually explains itself.
Bonuses, Commissions, and Overtime
Performance bonuses, sign-on incentives, commissions, and overtime pay are taxable wages that flow straight into Box 1.1Internal Revenue Service. Publication 525 (2025), Taxable and Nontaxable Income If your base salary is $65,000 but you earned $8,000 in overtime and received a $5,000 bonus, Box 1 starts at $78,000 before anything else is added.
These payments count as supplemental wages, and your employer withholds federal income tax on them at a flat 22 percent (or 37 percent once supplemental wages exceed $1 million for the year).2Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide The heavier withholding can make the deposit feel smaller than expected, but the full gross amount is what shows up on the W-2. A $5,000 bonus adds exactly $5,000 to Box 1, even if only $3,900 hit your bank account.
Stock-Based Compensation
Equity pay is one of the fastest ways a W-2 balloons past a stated salary. Three types show up most often, each taxed at a different moment.
Restricted Stock Units
When RSUs vest, the fair market value of the shares on the vesting date is treated as ordinary compensation.3Office of the Law Revision Counsel. 26 U.S.C. 83 – Property Transferred in Connection With Performance of Services Your employer reports the amount in Boxes 1, 3, and 5.4Internal Revenue Service. General Instructions for Forms W-2 and W-3 (2026) If 200 shares vest at $150 each, that alone adds $30,000 to your wages, easily overshadowing base pay in a strong year.
Nonstatutory Stock Options
Exercising nonstatutory (nonqualified) options triggers ordinary income equal to the spread between the exercise price and the stock’s fair market value on the exercise date.5Internal Revenue Service. Topic No. 427, Stock Options The amount lands in Box 1 and is called out in Box 12 with Code V.4Internal Revenue Service. General Instructions for Forms W-2 and W-3 (2026) Buying 500 shares at $20 when the market price is $50 adds $15,000 to your W-2.
Employee Stock Purchase Plans
An ESPP lets you buy company stock at a discount. If you sell the shares before meeting the required holding periods, the discount plus any additional gain up to the fair market value on the purchase date is reported as ordinary income on your W-2, even though the payout came from a stock sale rather than a paycheck.
Taxable Fringe Benefits
Several non-cash benefits count as income even though you never see them in a direct deposit.
Group-Term Life Insurance Over $50,000
Employer-provided group-term life insurance coverage above $50,000 generates taxable income equal to the IRS uniform premium cost of the excess coverage, based on your age, not what your employer actually pays the insurer.6Office of the Law Revision Counsel. 26 U.S.C. 79 – Group-Term Life Insurance Purchased for Employees7Internal Revenue Service. Group Term Life Insurance The amount appears in Box 12 with Code C and is already included in Box 1. It usually adds a few hundred dollars, more for older employees or larger policies.
Personal Use of a Company Vehicle
If you drive a company car for commuting or personal errands, the value of that personal use is added to your gross pay. Employers can calculate it using the vehicle’s fair market value, the standard mileage rate, or a flat $1.50 per one-way commute where allowed.8Internal Revenue Service. Publication 15-B (2026), Employer’s Tax Guide to Fringe Benefits Whatever method applies, the resulting dollar figure lands in Box 1.
Excess Dependent Care and Education Assistance
Employer-provided dependent care assistance is tax-free up to $7,500 per household in 2026 ($3,750 if married filing separately). Anything above that is added to Box 1.9Internal Revenue Service. Publication 15-B, Employer’s Tax Guide to Fringe Benefits Employer-paid educational assistance for tuition, fees, books, and supplies is excluded up to $5,250 per year; amounts beyond that become taxable.10Office of the Law Revision Counsel. 26 U.S.C. 127 – Educational Assistance Programs
Other Fringe Benefits
An off-site gym membership paid by your employer is taxable because no statutory exclusion covers it. On-premises athletic facilities the employer operates are excluded as long as substantially all use is by employees and their families.8Internal Revenue Service. Publication 15-B (2026), Employer’s Tax Guide to Fringe Benefits Employer-provided adoption assistance above $17,670 in 2026 is also added to your taxable wages.11Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
Taxable Reimbursements
Not every reimbursement is tax-free. When a payment is made outside of an accountable plan (one that requires you to document business expenses and return any excess), the full amount is treated as wages.
Moving and Relocation Expenses
Employer-paid moving costs are taxable income for civilian employees. The Tax Cuts and Jobs Act made these reimbursements taxable starting in 2018, and later legislation made that treatment permanent.12Internal Revenue Service. Moving Expenses to and From the United States Active-duty military members moving under orders are the only exception. A $12,000 relocation package lands in Box 1 in full.
Tax Gross-Ups
Some employers “gross up” a taxable reimbursement, paying extra to cover the tax you will owe on it. The gross-up itself is also taxable. A $12,000 relocation with a gross-up can push your W-2 up by $16,000 or more once the extra tax coverage is added.
Tips
Tips you reported to your employer during the year are included in Box 1 and also appear separately in Box 7 as Social Security tips.4Internal Revenue Service. General Instructions for Forms W-2 and W-3 (2026) A server with $20,000 in base wages and $25,000 in reported tips will see $45,000 in Box 1.
Allocated tips are handled differently. If you work at a large food or beverage establishment and your reported tips fall below a percentage of total sales, your employer may allocate additional tips to you. Those appear in Box 8 and are not included in Box 1.13Internal Revenue Service. Tips You are still generally responsible for reporting the Box 8 amount on your return unless your records show you received less.
Third-Party Sick Pay
Short-term disability payments from a third-party insurer can appear on your W-2 when your employer paid the premiums. Employer-funded disability benefits are taxable and are reported in Box 1 as wages.14Internal Revenue Service. Reporting Sick Pay Paid by Third Parties, Notice 2015-6 If you paid the premiums yourself through after-tax deductions, the benefits are not taxable and should not appear in Box 1. When you and your employer split the cost, only the portion attributable to the employer’s share is taxable.
Deferred Compensation Distributions
If you participate in a nonqualified deferred compensation plan, distributions are reported as wages in Box 1 in the year you receive them, with the amount also shown in Box 11.4Internal Revenue Service. General Instructions for Forms W-2 and W-3 (2026) In the first year of payouts, often at retirement or separation, the W-2 can be significantly higher than your final salary. Separately, if a plan fails the requirements of Section 409A, all previously deferred amounts can become immediately taxable, along with a 20 percent additional tax and interest.15Office of the Law Revision Counsel. 26 U.S.C. 409A – Inclusion in Gross Income of Deferred Compensation Under Nonqualified Deferred Compensation Plans That income appears in Box 1 and is flagged in Box 12 with Code Z.
Why Box 1, Box 3, and Box 5 Show Different Numbers
If Box 1 looks right but Box 3 or Box 5 is even higher, each box is measuring a slightly different version of your pay.
Box 1 is federal taxable wages: gross pay minus pre-tax retirement contributions (such as 401(k) or 403(b) deferrals) and certain other pre-tax deductions. Box 3 is Social Security wages. Box 5 is Medicare wages. Pre-tax retirement contributions reduce Box 1 but not Boxes 3 or 5, so those two boxes usually run higher than Box 1.4Internal Revenue Service. General Instructions for Forms W-2 and W-3 (2026)
Social Security wages in Box 3 are capped at $184,500 for 2026; above that, Box 3 stops. Medicare wages in Box 5 have no cap, which is why Box 5 is often the largest figure on the form.16Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
Box 12 codes are the fastest way to identify what pushed your wages up:
- Code C flags the taxable cost of group-term life insurance over $50,000, which is included in Box 1.7Internal Revenue Service. Group Term Life Insurance
- Codes D, E, and G show pre-tax 401(k), 403(b), and 457(b) contributions. These reduce Box 1 but not Boxes 3 and 5, which is why those boxes run higher.
- Code V shows income from exercising nonstatutory stock options, included in Boxes 1, 3, and 5.4Internal Revenue Service. General Instructions for Forms W-2 and W-3 (2026)
- Code Z reports income from a deferred compensation plan that failed Section 409A, included in Box 1.
- Code DD is the total cost of employer-sponsored health coverage. It is informational only and does not increase Box 1.
How to Check for a Payroll Error
Once you have accounted for the additions above, if the numbers still do not reconcile, a payroll mistake is possible. Compare your final pay stub of the year to your W-2. Year-to-date gross pay on that stub, plus any fringe benefit additions, should line up closely with Box 1 after pre-tax deductions.
If something is off, ask your employer’s payroll department to review the record. When an error is confirmed, the employer issues Form W-2c, a corrected wage and tax statement filed with both you and the Social Security Administration.17Internal Revenue Service. About Form W-2 C, Corrected Wage and Tax Statements Filing with an incorrect W-2 can trigger processing delays and later IRS notices, so it is worth resolving before you submit your return.
