What Is Adjusted Gross Income?

14. AGI

You’ve all probably heard of the term Adjusted Gross Income.

But what does that really mean?

Why do you have to get your AGI from your tax preparer, rather than just adding up your tax forms?

Well, that’s because there are several tax deductions that can be included in your Adjusted Gross Income calculation.

ADJUSTED GROSS INCOME VS. GROSS INCOME

When you think of your income, your gross income automatically pops into your head.

And rightfully so, unless you’re a tax preparer…

Of course, you need your gross income in order to calculate your adjusted gross income.

Your gross income consists of all the money you made throughout the tax year. And this also includes money you earn from other sources, not just your paycheck.

Here’s a list of potential income sources to include in your gross income:

These adjustments are typically referred to as “above-the-line” deductions. Since the adjustments are applied before you take your itemized or standard deduction.

To reach your Adjusted Gross Income, you take the total gross income minus your total adjustments.

Let’s look at an example.

Gross Income$90,000Form W-2 $ 49,720
Form W-2 $40,200
Form 1099-INT $80
Adjustments$500Educator Expenses $250
Student loan interest deduction $250
Adjusted Gross Income$89,500 

You’ve reduced your taxable income by $500!

Being aware of these adjustments can save you taxes. Even if you have a tax preparer it is beneficial to be educated on the adjustments that can impact your tax return.

Your tax preparer can only prepare your return with the information that you provide. Therefore, if you do not provide information about adjustments, these adjustments may be missed!

If you’re completing your return yourself, the tax software should automatically calculate your Adjusted Gross Income (AGI) through the tax interview process. Again, that depends on the information you provide, so being knowledgeable on the adjustments you get is beneficial!
