What Is Box 1?

Box 1 on a W-2 is the wages, tips and other compensation section of the W-2. What does this include? According to the IRS instructions for filling out Form W-2, that means your salary, wages, tips, bonus, commission and other compensation you received that is considered taxable income. You can see a detailed list of what is considered taxable wages, tips and other compensation in IRS publication titled "General Instructions for Forms W-2 and W-3" on page 16 under the heading, "Box 1 – Wages, tips other compensation."

Different From Your Last Stub?

If the amount in Box 1 differs from the gross pay listed on your last pay stub, there could be several reasons, explains Automatic Payment Systems. This is because your pay stub shows your gross earnings before deductions, while your W-2 shows only your income after pre-tax deductions.

Pre-tax deductions include a 401(k) or other tax-advantaged retirement account contribution you make, employer-provided health insurance or other benefits like a Flexible Spending Account, Health Savings Account, child care plans or dental, life, disability or vision insurance.

What Does it Not Include?

Box 1 does not include all reimbursements you received from your employer. For example, if you had ​$1,200​ worth of travel expenses (such as airfare, hotel, meals, taxis and parking) and your company reimbursed you via an expense report, this ​$1,200​ is not included as wages, tips or other compensation. If your Box 3 and Box 5 wages differ from your Box 1 amount, that's because they show your wages subject to Social Security tax (Box 3) and Medicare (Box 5).
