Above-the-Line Deductions: 10 Ways to Reduce Your AGI in 2026

Most Americans know about the standard deduction. Fewer than half actively use the 10 above-the-line deductions that reduce adjusted gross income before the standard deduction is even applied — and some of these deductions are worth more than $15,000 per year for the right taxpayer.

Why AGI reduction is more powerful than it appears

Your adjusted gross income (AGI) is the single most important number on your tax return. It determines eligibility for:

• Roth IRA contributions (phased out above $150,000 for single filers in 2026)
• Traditional IRA deductibility (varies by workplace plan coverage)
• Child Tax Credit phase-out (beginning at $200,000 single / $400,000 MFJ)
• Student loan interest deductibility
• ACA premium tax credit eligibility
• Medicare IRMAA premium surcharges (beginning at $106,000 MAGI for single filers in 2026)

Unlike itemized deductions, above-the-line deductions reduce AGI regardless of whether you take the standard deduction or itemize. They are available to everyone who has the qualifying expense — employees, retirees, and self-employed individuals alike.

The 10 most impactful above-the-line deductions

1. Traditional IRA contribution deduction Up to $7,000 in 2026 ($8,000 if age 50 or older). Fully deductible if neither you nor your spouse is covered by a workplace retirement plan. If you or your spouse has a 401k, the deduction phases out between $79,000 and $89,000 for single filers and between $126,000 and $146,000 for MFJ in 2026.

2. Health Savings Account (HSA) contributions Up to $4,300 for self-only coverage or $8,550 for family coverage in 2026 (additional $1,000 catch-up if age 55 or older). Available to anyone enrolled in a qualifying high-deductible health plan. Contributions reduce AGI even when made directly — not just through payroll deduction.

3. Self-employed health insurance deduction Self-employed individuals can deduct 100% of health, dental, and long-term care insurance premiums paid for themselves, a spouse, and dependents. For a freelancer or LLC owner paying $18,000 per year in family premiums, this is $18,000 of direct AGI reduction.

4. One-half of self-employment tax Self-employed individuals pay both the employee and employer share of FICA — totaling 15.3% of net SE income. The employer-equivalent half (7.65%) is deductible above-the-line. On $80,000 of net self-employment income, this deduction is approximately $5,652.

5. SEP-IRA, SIMPLE IRA, or Solo 401k contributions Self-employed individuals can contribute up to 25% of net SE income to a SEP-IRA (capped at $70,000 in 2026). On $100,000 of net self-employment income, a SEP-IRA contribution of approximately $18,587 is deductible. This is the largest single above-the-line deduction available to most self-employed taxpayers.

6. Student loan interest deduction Up to $2,500 per year in interest paid on qualified education loans. Phases out at $80,000 to $95,000 for single filers and $165,000 to $195,000 for married filing jointly in 2026.

7. Alimony paid under pre-2019 agreements Alimony paid under divorce or separation agreements executed before January 1, 2019 remains deductible by the payer and taxable to the recipient. Agreements finalized after December 31, 2018 eliminated the deduction under TCJA.

8. Educator expense deduction K-12 teachers, counselors, and principals who spend their own money on classroom supplies can deduct up to $300 ($600 if both spouses are educators filing jointly). Eligible expenses include books, supplies, computer equipment, and COVID-19 protective items.

9. Penalty on early withdrawal from savings If you paid a financial institution's penalty for withdrawing from a CD or savings account before maturity, the penalty amount is fully deductible — even if it is only $50.

10. Jury duty pay turned over to employer If you were required to turn your jury duty pay over to your employer and your employer continued your full salary during service, you can deduct the jury pay you remitted.

The stacking strategy

The most powerful AGI reduction combines multiple above-the-line deductions simultaneously. A self-employed individual earning $90,000 of net business income who contributes $16,000 to a SEP-IRA, pays $14,000 in self-employed health insurance premiums, and contributes $4,300 to an HSA reduces AGI by approximately $36,803 (including the SE tax deduction). The $90,000 gross income becomes roughly $53,197 in AGI — potentially keeping them below the Roth IRA income limit and below the student loan interest phase-out.
