What is a W-2 form?
A W-2 form is a U.S. tax document that an employer gives to its employees, showing the taxable income, wages, and other compensation earned by employees in the year. The document is shared at the end of January every year.
As an employee, you use this document to report your earnings to the IRS and to file your return during tax season. The key structure of the W-2 form is as follows:
Wages Earned
- Box 1 (Wages, tips, and other compensation) – This represents the taxable income after deducting pre-tax deductions.
- Box 3 (Social Security wages) – This box represents the earnings subject to Social Security tax. The amount is different from Box 1.
- Box 5 (Medicare wages and tips) – This box shows income subject to Medicare taxes, which differ from other wage amounts.
Taxes Withhold
It shows the amount of tax that was deducted from your total paycheck throughout the year.
- Box 2 (Federal income tax withheld) – The total amount of Federal taxes the employer withheld.
- Box 4 (Social Security tax withheld) – The total amount of taxes that the employer withheld as Social Security tax.
- Box 6 (Medicare tax withheld) – The total amount of taxes the employer withheld as Medicare tax.
- Box 17 (State income tax withheld) – The total amount of state income tax deducted from the total salary, if applicable.
- Box 19 (Local income tax withheld) – Any local or city income taxes that are deducted from the paycheck.
Employee benefits and deductions
The W-2 form also includes employee benefits and deductions, which are as follows:
- Box 12 (Benefit and deduction codes) – This box includes deductions for 401(k), employer-sponsored health insurance, and other retirement plans, each with a specific letter code. Some of the codes are as follows:
-
→Code D: 401(k) retirement contributions
→Code E: 403(b) retirement contributions
→Code W: Health Savings Account (HSA) contributions
- Box 13 (Retirement plan checkbox) – It indicates your participation in the employer-sponsored retirement plan. Other than that, you can also mention the third-party sick pay that you receive from a third party instead of your employer.
- Box 14 (Additional information) – You can mention union dues, tuition assistance, charitable contributions, and other deductions here.

What is gross income?
Gross income refers to the total income an employee earns before any deductions are applied. This total income is not limited to the salary received from the employer. It includes property, money, and the value of received services.
Gross earnings may include wages, bonuses, freelance earnings ($400 or more), rental income, and other sources.
For instance, suppose a person earns income in the following ways –
- Wage – $3,60,000 annually.
- Bonus earning – $1000
- Freelancing income – $200
At the end of the financial year, when he calculates gross income, he needs to consider all of the above earnings, regardless of their sources.
$3,60,000 + $1000 + $200 = $3,61,200
So, the gross income of the person is $3,61,200
Why is it important to understand gross income?
Understanding gross income helps you determine your taxable income and the net income you actually receive.
Calculating the total taxable income
It becomes easier to identify the total taxable income once you understand the gross income. You can determine your adjusted gross income (AGI), which is useful in determining various deductions.
You can also determine your modified adjusted gross income (MAGI), which is important for the tax process. It includes certain added-back deductions in addition to AGI, so it usually equals or exceeds AGI.
Determining the net income
With a clear understanding of gross income, it is easy to determine the total take-home pay. This take-home pay is the amount of money you receive after taxes and other deductions.
For full-time employees in the US, the employer already deducts the applicable tax based on the W-4 form. The applicable taxes are State Income Tax, Social Security Tax, Insurance, and Medicare.
Streamline the loan process
Lenders often use gross income to evaluate your financial condition. Gross income gives clear insights and helps to make informed decisions when processing the loan. Thus, understanding annual gross income on a W-2 is an important metric when you apply for a loan.
Finding the credit limits
Credit card issuers often use gross income to determine the credit limits. A higher income clearly indicates the financial stability of an individual or a business. Thus, it becomes easier for lenders to assess repayment capacity when determining the credit limit.
How to determine annual gross income from a W-2?

Determining the gross income from a W-2 is not a big deal. However, a systematic approach is required. So, how do you calculate gross income? Here are the steps:
1. Start with Box 1
Understanding gross income on a W-2 form requires recognizing that Box 1 (wages, tips, other compensation) does not contain certain pre-tax benefits. This amount will be lower than your total gross income because of certain deductions applied. Always treat Box 1 as a starting point when you think about how to find gross income on a W-2.
2. Add pre-tax deductions
To estimate the true gross income, you need to add back the following deductions:
- Health insurance premium
- Retirement contributions such as 401(k)
- Other pre-tax benefits
3. Sum all the additional sources of income
You must include other sources of income and add them all together. These sources can be any of the following
- Rental income
- Interest earning
- Taxable alimony
- Capital gains
- Dividends
- Gigs or freelancing work
4. Add all the income sources together
Finally, you need to sum the income reported on the W-2 form and from other sources.
Knowing how to find gross pay on your W-2 is useful for understanding your taxable income and overall financial planning & management
On the W-2 form, Box 3 and Box 5 show Social Security wages and Medicare wages & tips, respectively. If these boxes have a higher value than Box 1, it means pre-tax deductions are in effect.
What is gross monthly income?
Gross monthly income refers to the total amount of money that you earn in a month before any kind of deductions. These deductions may be taxes, insurance, retirement contributions, and other withholdings.
Unlike annual income, which is calculated yearly, gross monthly income is calculated on the basis of each month.
How to calculate gross monthly income?
Similar to annual income, gross monthly income can be calculated. However, in this case, you need to divide your annual income by 12 to get the monthly figure. Here are the steps you need to follow when thinking about how to find gross income on a W-2, month-wise.
1. Find your annual income
When using the W-2 form, look at Box 1 (wages, tips, and other compensation).
2. Add pre-tax deductions
This is optional, but it gives a more accurate figure. To get more accurate information, you need to add back pre-tax deductions. Additionally, you can add insurance, retirement contributions, and other benefits.
3. Divide by 12 to get the monthly gross income
Convert the total annual income to monthly income by dividing it by 12. The end result is the monthly gross income that you get each month before any deductions.
What is adjusted gross income?
Adjusted Gross Income (AGI) is the total income that an individual earns after certain specific deductions. The following are some deductions that are allowed by the IRS:
- Student loan interest
- Retirement contributions
- Educator expenditure
- Health savings account (HSA) contributions
- Self-employment deductions
The simpler formula for calculating the adjusted gross income is as follows:
One of the major benefits of tracking AGI is that you get the right idea of reducing your eligible deductions legally. This helps to reduce your tax burden and save your money. It also contributes to correct tax filing and financial planning.
