Schedule 1, Additional Income and Adjustments to Income, is the supporting document that reports income earned that you can’t report on other tax forms and figure out adjusted gross income. This tax form is pretty much mandatory to file as you need to calculate your adjusted gross income to clarify eligibility for further tax deductions and credits.
You’ll also reduce taxable income as you’re calculating adjusted gross income. These adjustments are also known as above-the-line deductions, and you can claim these without itemizing taxes. You can both take the standard deduction and claim the adjustments on Schedule 1.
