Why Do I Need My Prior Year’s AGI?

There are a couple of reasons why your AGI is important. For starters, your AGI is used to calculate your taxable income. It is also used to verify your identity when you e-file your taxes. The IRS uses your prior year’s AGI to confirm you are who you say you are when you e-file. Another reason you might need your AGI from last year is to determine monthly Medicare premiums. In this instance, your MAGI will be analyzed. This is your modified AGI, which is your adjusted gross income minus certain tax deductions and tax-exempt interest.

What is Adjusted Gross Income?

If you haven’t figured it out by now, AGI stands for adjusted gross income, and it is the figure the IRS uses to determine taxable income. AGI is your gross income minus certain adjustments. To calculate your adjusted gross incomes you will need records from all income streams. This includes wages from your job, investments, real estate, businesses, spousal support, awards and prizes, social security, pensions, and unemployment. All of this is combined with your gross income. Next, you will leverage your expenses such as business expenses, retirement contributions, HSA contributions, self-employment taxes, alimony paid, student loan interest, tuition, and fees, to name a few. Once you have taken all of the deductions available to you, you will have your AGI.

How to Find Your Prior Year AGI

The most common reason you will need last year’s AGI is to e-file your tax return. When it comes time to file your taxes, you have a couple of ways to locate your prior year AGI.

Last Year’s Tax Return
