If you don't itemize, you can still deduct "above-the-line" adjustments to income, such as contributions to a Traditional IRA or Health Savings Account (HSA), student loan interest, educator expenses, self-employment tax, and penalties on early savings withdrawals, which lower your Adjusted Gross Income (AGI) before you take the standard deduction. These deductions reduce your taxable income regardless of whether you itemize or take the standard deduction, helping lower your overall tax bill.
