Tax Credits and Deductions: How to Reduce Your Taxable Income and Tax Liability

Every year, millions of taxpayers file federal income tax returns — and whether they realize it or not, each one makes decisions about credits and deductions that directly affect how much they owe.

Understanding how tax credits and deductions work is one of the simplest ways to put the tax code to work for you instead of against you. At The Art and Science of Successful Planning (ASOFSP) in Fort Myers, Florida, we help Southwest Florida families and retirees build tax planning strategies around these two building blocks — before decisions have to be made in a rush every April.

Tax Credits vs. Deductions: What’s the Difference?

Both tax credits and tax deductions lower what you owe the IRS, but they work in different ways:

• Tax credits are subtracted directly, dollar-for-dollar, from your actual tax liability — making them generally more powerful than deductions of the same size.
• Tax deductions reduce the amount of income that’s subject to tax in the first place, lowering your taxable income before your tax bill is calculated.

Both credits and deductions typically come with income limits or phase-outs, so it’s worth talking to a qualified tax or financial professional about your specific situation.

What Are Tax Credits and How Do They Work?

Because tax credits reduce your tax bill directly, they often deliver more savings than a deduction of equal size. Here are a few common examples:

Child Tax Credit

Families with dependent children under age 17 may qualify for a credit of up to $2,000 per qualifying child, depending on income level.

American Opportunity Credit

Eligible students may claim up to $2,500 per student toward tuition costs for up to four years of post-secondary education.

Child and Dependent Care Credit

If you pay someone to care for a child under 13 or another qualifying dependent so you can work, you may be able to claim up to $3,000 for one qualifying individual, or up to $6,000 for two or more.

What Are Tax Deductions and How Do They Reduce Taxable Income?

Deductions lower the amount of income the IRS taxes, which in turn reduces your overall liability. Common ways to reduce taxable income through deductions include:

• Charitable contributions — Donations to qualifying charitable organizations may be deductible, including cash gifts, the fair market value of donated property, and certain out-of-pocket costs incurred while volunteering.
• Mortgage interest — Under rules updated by the 2017 Tax Cuts and Jobs Act, you may be able to deduct interest paid on a loan secured by your primary or secondary residence.
• Retirement account contributions — Contributions to a qualified retirement plan, such as an IRA, may be deductible. For 2026, the IRA contribution limit is $7,500 for those under age 50, and $8,600 for those age 50 and older.
• Medical and dental expenses — You may deduct unreimbursed medical and dental expenses that exceed 7.5% of your adjusted gross income (AGI), provided you itemize deductions.
