10 Above the Line Deductions Every Taxpayer Should Know About

The following is a list of “must know” above-the-line deductions (i.e., adjustments) that every taxpayer should know:

1) Educator Expenses

What it is: K–12 teachers, counselors, principals, and classroom aides can deduct certain unreimbursed classroom costs (supplies, books, software, etc.) up to an IRS-set annual cap.
Example: Ms. Green buys $420 of classroom supplies and isn’t reimbursed. She can deduct up to the annual educator limit directly against income.

2) Health Savings Account (HSA) Contributions

What it is: If you’re covered by a qualifying high-deductible health plan, you can contribute to an HSA. Contributions are an adjustment to income, the account grows tax-free, and withdrawals for qualified medical expenses are tax-free.
Example: Jamal contributes to his HSA through payroll and adds more on his own before the tax deadline. Those extra dollars reduce his AGI and still grow for future medical costs.

3) Traditional IRA Deduction

What it is: Contributions to a traditional IRA may be deductible, depending on your income, filing status, and whether you (or a spouse) are covered by a retirement plan at work.
Example: Ana, not covered at work, contributes to a traditional IRA. Her contribution is deductible and lowers her AGI—even if she doesn’t itemize.

4) Student Loan Interest

What it is: You may deduct up to $2,500 of qualifying student loan interest paid during the year (phased out at higher incomes). You don’t need to itemize to take it.
Example: Chris pays $1,400 of interest on federal loans. He takes a $1,400 above-the-line deduction, reducing taxable income dollar-for-dollar.

5) One-Half of Self-Employment Tax

What it is: Self-employed folks pay both the employer and employee share of FICA via SE tax. The IRS lets you deduct half of that SE tax as an adjustment to income.
Example: Priya’s Schedule C shows SE tax of $6,800. She deducts $3,400 above the line—automatic savings most DIY software glosses over.

6) Self-Employed Health Insurance Premiums

What it is: If you have net self-employment income and aren’t eligible for employer coverage (including your spouse’s plan), you may deduct premiums for medical, dental, and qualified long-term care for you, your spouse, and dependents.
Example: Mike runs a consulting business and buys his own family plan. He deducts those premiums directly against income (subject to rules/limits).

7) Retirement Contributions for the Self-Employed (SEP, SIMPLE, Solo 401(k))

What it is: Contributions you make as the employer to a SEP-IRA, SIMPLE IRA, or Solo 401(k) are adjustments to income (separate from any elective deferrals).
Example: Keisha, a sole proprietor, contributes to her SEP-IRA after year-end but before her filing deadline. That contribution reduces this year’s AGI and builds retirement at once.

8) Alimony Paid (for Certain Older Agreements)

What it is: Only alimony paid under divorce or separation agreements executed before 2019 (and not modified to adopt the new law) is deductible by the payer and taxable to the recipient.
Example: Under a 2017 decree, Jordan pays court-ordered alimony. Those payments remain an above-the-line deduction because the agreement predates 2019.

9) Penalty on Early Withdrawal of Savings

What it is: If your bank/CD charges a penalty when you cash out early, that penalty is deductible as an adjustment to income.
Example: Elena breaks a CD to cover home repairs and forfeits $375 of interest as a penalty. She deducts the $375 above the line.

10) Jury Duty Pay Turned Over to Your Employer

What it is: If your employer continues your regular pay while you serve and requires you to sign over your jury duty check, you can deduct the amount you remitted.
Example: Devon receives $90 from the court for jury service and turns it over to his employer per company policy. He claims a $90 adjustment to income.

Why this list matters

Above-the-line deductions reduce AGI, which can:

  • Increase eligibility for credits (Child Tax Credit, education credits, etc.).
  • Reduce phase-outs and the 3.8% Net Investment Income Tax exposure.
  • Improve medical and miscellaneous threshold math (where applicable).

How RDA Tax Services helps (and why clients stay)

  • We ask better questions. Many “missed” deductions are really missed questions. We uncover HSA eligibility, self-employed health insurance nuances, jury-duty offsets, and educator expenses that software can’t spot by itself.
  • We plan year-round. Timing matters—funding a SEP vs. Solo 401(k), coordinating HSA/IRA moves, or shifting how you pay medical premiums can change your tax outcome.
  • We verify eligibility. Alimony rules, coverage tests for the self-employed health deduction, and IRA phase-outs are detail-heavy; we keep you compliant and maximized.

Bottom line: Don’t tip the IRS by accident. Let RDA Tax Services translate your life into legal deductions—so your AGI is lower, your credits work harder, and your return is audit-tough.
