Who benefits from tax breaks in the Internal Revenue Code

Complaining about taxes is in vogue these days. We think we pay too much and others (mostly the wealthy) pay too little.

Yes, there are different types of taxes, but the big one is federal income taxes. Our perception of what we pay is sometimes misleading. Some people think they pay the percentages shown in the tax brackets (marginal rates). In reality it is our effective tax rate that matters.

Average Effective Federal Tax Rates by Income Group

The effective tax rate is the average percentage of your income that you actually pay in tax, rather than the rate on your last dollar of income. It is usually calculated as total tax paid divided by total income or taxable income, depending on the context.

According to the latest IRS data analyzed by the Tax Foundation, average effective federal income tax rates rise significantly as adjusted gross income (AGI) increases.

Effective Federal Income Tax Rate

Top 1% $663,164 and above 26.1%

Top 5% to 1% $261,591 to $663,163 18.8%%

Top 10% to 5% $178,611 to $261,590 14.3%

Top 25% to 10% $96,573 to $178,610 10.7%

Top 50% to 25% $50,400 to $96,572 7.7%

Bottom 50% Under $50,399 3.7%%

Note on the Bottom 50%: The 3.7% figure represents the average income tax rate. When factoring in refundable tax credits (like the Earned Income Tax Credit or Child Tax Credit), many households in the bottom tiers have a net-negative federal income tax liability, though they still pay payroll taxes (Social Security and Medicare).

Under the current Internal Revenue Code (IRC), the vast majority of “average Americans” benefit from a core group of tax breaks. These are generally divided into deductions (which lower the amount of income you are taxed on) and credits (which reduce your tax bill dollar-for-dollar).

The most impactful provisions for middle-class, working, and retired families include:

1. Major Deductions (Lowering Taxable Income)

Deductions reduce your overall tax liability based on your marginal tax bracket.

• The Standard Deduction: This is the most widely used tax break, claimed by roughly 90% of all taxpayers. ^{It eliminates a massive chunk of income from federal taxation right off the top. For the 2025/2026 tax years, the standard deduction amounts are:}
  • Married Filing Jointly: $31,500
  • Head of Household: $23,625
  • Single / Married Filing Separately: $15,750
  • Note: Taxpayers who are 65 or older or blind receive an additional enhanced senior standard deduction amount on top of these base numbers.
• Pre-Tax Retirement Contributions: Contributions made to workplace 401(k) or 403(b) plans bypass federal income tax automatically on your W-2. Additionally, traditional IRA contributions can be deducted “above-the-line” (meaning you don’t have to itemize to claim them), though this phases out at higher income levels if you have a workplace plan.
• Health Savings Account (HSA) Contributions: For individuals with a high-deductible health plan, contributions to an HSA are 100% tax-deductible above-the-line, grow tax-free, and can be withdrawn completely tax-free for medical expenses.

2. Powerful Tax Credits (Dollar-for-Dollar Reductions)

Because credits directly subtract from the final amount of tax you owe, they are incredibly valuable.

• The Child Tax Credit (CTC): For families with children under age 17, this credit is worth up to $2,200 per qualifying child. ^{It features a substantial refundable portion (up to $1,700), meaning that if the credit reduces your tax liability below zero, the IRS will send the rest back to you as a refund check.}
• Earned Income Tax Credit (EITC): A robust, fully refundable credit specifically structured for low-to-moderate-income working individuals and families. ^{The amount scales depending on your income and the number of dependents you claim.}
• Higher Education Credits:
  • American Opportunity Tax Credit (AOTC): Provides up to $2,500 per student for the first four years of higher education (with up to 40% of it being refundable).
  • Lifetime Learning Credit (LLC): Provides up to $2,000 per year for graduate school, undergraduate courses, or professional tuition/job-training courses (non-refundable).
• The Saver’s Credit: Officially known as the Retirement Savings Contributions Credit, this gives lower- and middle-income workers a tax credit of up to 50% of their contributions to an IRA or 401(k), maxing out at $1,000 ($2,000 if married filing jointly).

3. Highly Common “Exclusions”

While not listed as deductions on a Form 1040, exclusions are income streams that the IRC completely exempts from being taxed in the first place:

The Health Insurance Exclusion: The single largest tax break in America is the exclusion of employer-sponsored health insurance premiums. If your employer pays for or splits your medical coverage, that money is entirely exempt from both federal income tax and payroll taxes.

• Capital Gains Exemption on Home Sales: If you own a home and sell it, the IRC allows you to exclude up to $250,000 (single) or $500,000 (married filing jointly) of the profit from your taxes, provided it was your primary residence for at least two of the past five years.
• And then there are Roth retirement accounts providing tax- free income – used primarily by middle and upper middle income earners.
