Adjustments to Income, also called “above-the-line deductions,” are specific deductions subtracted from your gross income to calculate adjusted gross income (AGI). These deductions are particularly valuable because they reduce your income regardless of whether you itemize deductions or claim the standard deduction, and they lower your AGI, which affects eligibility for numerous other tax benefits and credits that phase out at higher income levels.
Adjustments to income are reported on Schedule 1 (Additional Income and Adjustments to Income), Part II, with the total flowing to Form 1040. Common adjustments include educator expenses (up to $300 for qualified K-12 teachers), certain business expenses for reservists, performing artists, and fee-basis government officials, health savings account (HSA) contributions, moving expenses for active-duty military, deductible part of self-employment tax (one-half of self-employment tax paid), self-employed SEP, SIMPLE, and qualified retirement plan contributions, self-employed health insurance premiums, penalties on early withdrawal of savings, alimony paid for pre-2019 divorce agreements, traditional IRA contributions (subject to income limits if covered by employer plan), and student loan interest deduction (up to $2,500).
These adjustments are called “above-the-line” because they appear before the line on Form 1040 that shows AGI, distinguishing them from “below-the-line” deductions like the standard deduction or itemized deductions. This positioning makes them universally beneficial to taxpayers who qualify, providing tax savings without the need to exceed standard deduction thresholds.
Lowering your AGI through adjustments to income creates cascading tax benefits beyond the immediate deduction. Lower AGI can increase eligibility for the Earned Income Tax Credit, education credits, IRA contributions, Roth IRA conversions, premium tax credits for health insurance, child tax credit amounts, and numerous other income-tested benefits. It can also reduce the taxable portion of Social Security benefits and help avoid the 3.8% Net Investment Income Tax.
Strategic use of adjustments to income—such as maximizing HSA or retirement contributions—provides powerful tax planning opportunities by simultaneously reducing current tax liability while building wealth and improving eligibility for other valuable tax benefits.
